 Definitions
 bastnasite – a mixed lanthanide fluoro-carbonate mineral (LaCO 3 F) that currently provides the bulk of the world's supply of the LREEs. Bastnasite and monazite are the two most common sources of cerium and other REEs. Bastnasite is found in carbonatites, carbonate rocks of igneous derivation.
 beneficiation – operations that concentrate and separate mineral values in ore from waste material, and typically include, but are not limited to, crushing, grinding, washing, filtration, and leaching.
 cerium ("Ce") – a soft, silvery, ductile metallic element that easily oxidizes in air. Ce is the most abundant of the REEs and is found in a number of minerals, including monazite and bastnasite. Ce has two relatively stable oxidation states (Ce3+ and Ce4+), enabling both the storage of oxygen and its widespread use in catalytic converters. Ce is also widely used in glass polishing.

 concentrate – a mineral beneficiation product that generally describes the material that is produced after crushing and grinding ore, effecting significant separation of gangue (waste) minerals from the desired metal and/or metallic minerals, and discarding the waste minerals. The resulting "concentrate" of minerals typically has an order of magnitude higher content of minerals than does the beginning ore material.
 CREE – critical rare earth elements – Nd, Eu, Dy, Tb and Y were identified by the DoE as "critical" in its 2011 Critical Materials Strategy Report. CREEs are those projected by the DoE to have the greatest economic importance for clean energy development and the highest risk of supply disruption. The Company includes Pr as a CREE because of its use in conjunction with Nd in didymium as a raw material for high-intensity permanent magnets.
 didymium – a mixture of the elements Pr and Nd. Didymium is used as a raw material for the manufacture of high-intensity permanent magnets. It is used in safety glasses for glassblowing and blacksmithing, especially when a gas (propane) powered forge is used, where it provides a filter which selectively blocks the yellowish light at 589 nm emitted by the hot sodium in the glass, without having a detrimental effect on general vision, unlike dark welder's glasses.
 Dy – dysprosium (a soft metallic element of the lanthanide series, mainly used in high-performance, permanent magnets). Dy has a high melting point and absorbs neutrons well. It is therefore also used in nuclear control rods to help control nuclear reactions. Dy is also used in laser generating materials.
 Eu – europium (a very rare metallic element that is the softest member of the lanthanide series). It is used in making color television tubes and lasers and as a neutron absorber in nuclear research. It is desirable due to its photon emission. Excitation of the Eu atom, by absorption of electrons or by UV radiation, results in changes in energy levels that create a visible emission. Almost all practical uses of Eu utilize this luminescent behavior.
 fault – a surface or zone of rock fracture along which there has been displacement.
 Feasibility Study ("FS") – a comprehensive study of a mineral deposit in which all geological, engineering, legal, operating, economic, social, environmental, and other relevant factors are considered in sufficient detail that it could reasonably serve as the basis for a final decision to develop the deposit for mineral production.
 FMR – mineralization that includes iron oxide, manganese oxide and REE.
 Gd – gadolinium ( a malleable, ductile metallic element of the lanthanide series that has seven natural isotopes and 11 artificial isotopes). Two of the natural isotopes, Gd 155 and Gd 157, are the best-known neutron absorbers. Gd is used to improve the heat and corrosion resistance of iron, chromium, and various alloys in medicine as a contrast medium for magnetic resonance imaging and as a radioisotope in bone mineral analysis.
 geochemical – related to the distribution and amounts of the chemical elements in minerals, ores, rocks, solids, water and the atmosphere.
 geophysical – related to the mechanical, electrical, gravitational, and magnetic properties of the earth's crust.
 GHG – greenhouse gases
 grade – quantity of metal per unit weight of host material.
 HREEs – heavy rare earth elements – defined as the elements Tb, Dy, Ho, Er, Tm, Yb, Lu and Y.
 La – lanthanum ( the first metallic element of the lanthanide series). La is a strategically important rare earth element due to its use in fluid cracking catalysts ("FCC"), which are used in the production of transportation and aircraft fuel. La is also used in fuel cells and batteries.
 LREEs – light rare earth elements, defined as the elements La, Ce, Pr, Nd, Pm, Sm, Eu and Gd.

 mineral – a naturally occurring, inorganic crystalline material having a definite chemical composition.
 mineralization – a natural accumulation or concentration of one or more minerals in rocks or soil. Also, the process by which minerals are introduced or concentrated in rocks or soil.
 monazite – a reddish-brown rare earth phosphate mineral. Monazite-group minerals are typically accompanied by elevated concentrations of uranium and thorium. This has historically limited the processing of monazite. However, this mineral is becoming more attractive because it typically has elevated concentrations of HREEs.
 Nd – neodymium (a metallic element of the lanthanide series, occurring principally in REE fluorocarbonate and monazite minerals). Nd is a key constituent of Neodymium-Iron-Boron ("NdFeB") permanent magnets and an additive to capacitor dielectrics. NdFeB magnets maximize the power/weight ratio and are found in a large variety of motors, generators, sensors, and hard disk drives. Capacitors containing Nd are found in cellular telephones, computers and nearly all other electronic devices. A minor application of Nd is for lasers.
 NdFeB – Neodymium-Iron-Boron compound used to manufacture permanent rare earth magnets.
 NI 43-101 – National Instrument 43-101 – Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators.
 open pit – surface mining in which the ore is extracted from a pit or quarry. The geometry of the pit will vary with the characteristics of the ore body.
 ore – mineral-bearing rock.
 ore body – a mostly solid and fairly continuous mass of mineralization.
 Ox – oxide mineralization.
 OxCa – oxide carbonate.
 oxide – for purposes of the deposits found at the Bear Lodge Property, rare earth bearing mineralized material that results from the complete oxidation by natural processes of sulfide-bearing material.
 PFS – preliminary feasibility study or pre-feasibility study. Each mean a comprehensive study of the viability of a mineral project that has advanced to a stage where the mining method, in the case of underground mining, or the pit configuration, in the case of an open pit, has been established and an effective method of mineral processing and/or beneficiation has been determined. It includes a financial analysis based on reasonable assumptions of technical, engineering, legal, operating, economic, social, and environmental factors and the evaluation of other relevant factors that are sufficient for a Qualified Person, acting reasonably, to determine if all or part of any mineral resource may be classified as a Mineral Reserve under NI 43-101 standards.
 Pr – praseodymium (a metallic element that constitutes about 4% of the lanthanide content of bastnasite and has a few specific applications, based mainly on its optical properties). It is a common coloring pigment, and is used in photographic filters, airport signal lenses, and welder's glasses. Because it chemically and magnetically is so similar to its periodic chart neighbors Nd and La, Pr is typically found in small amounts in applications where Nd and La are important, such as NdFeB magnets and catalysts. These latter applications are actually the largest uses for Pr because the magnet and catalyst markets are so large. Thus, Pr plays an important role in extending the availability of the more widely used Nd and La.
 RC (reverse circulation) drilling – a rotary drilling method using either a hammer or a tri-cone bit to produce rock cuttings that are forced upward from the bottom of the drill hole to the surface through an inner tube, using liquid and/or air pressure moving downward through an outer tube.

 recovery – the percentage of contained metal actually extracted from ore in the course of processing and/or beneficiating such ore.
 REEs – rare earth elements. a group of metallic elements with unique chemical, catalytic, magnetic, metallurgical, and phosphorescent properties.
 Sm – samarium (a metallic element of the lanthanide series predominantly used to produce Sm cobalt magnets). Although these magnets are slightly less powerful than NdFeB magnets at room temperature, Sm cobalt magnets can be used over a wider range of temperatures and are less susceptible to corrosion.
 stockwork – complex system of structurally controlled or randomly oriented veins that can be standalone ore bodies or occur on the periphery of larger veins. They are also referred to as "stringer zones."
 strike – the direction or trend that a structural surface (e.g., an ore bedding or fault plane) takes as it intersects the horizontal.
 sulfide – a mineral combining sulfur and base metals, such as iron and less commonly copper, lead, zinc and/or molybdenum; metallic sulfur bearing mineral associated with primary REE mineralization.

 TRS – the technical report summary, dated February 29, 2024, relating to the Bear Lodge REE Project prepared in compliance with Item 601(b)(96) and Subpart 1300 of Regulation S-K, which was filed as Exhibit 96.1 to the Company's Current Report on Form 8-K filed on March 4, 2024.
 vein – a sheet like body of mineralized rock. On many properties, veins may consist largely of quartz gangue. However, on the Bear Lodge Property, veins can contain a variable assemblage that includes, but is not limited to, gangue minerals like iron and manganese oxides, quartz, calcite, clay, apatite and/or potassium feldspar with or without ore minerals.
 Y – Yttrium is primarily recovered from monazite resources and is used with iron in the manufacture of microwave communication equipment.

 ITEM 1. BUSINESS
 Rare Element was incorporated under the laws of the Province of British Columbia, Canada on June 3, 1999 as Spartacus Capital Inc. We are currently governed under the Business Corporations Act (British Columbia) (the "BCBCA"). Our executive office address is P.O. Box 271049, Littleton, Colorado 80127. The telephone number for our executive office is (720) 278-2460. We maintain a corporate website at www.rareelementresources.com.
 Originally organized as a "capital pool" company whose activities were focused on the identification and completion of a qualifying transaction as required by the rules of the TSX Venture Exchange ("TSX-V"), we transitioned to a "venture company" on July 25, 2003, coincident with (1) the completion of a reverse takeover acquisition of Rare Element Holdings Ltd. (the qualifying transaction), (2) a name change of "Spartacus Capital Inc." to "Rare Element Resources Ltd.", and (3) the completion of a private placement. The Company's main assets include its proprietary rare earth processing and/or beneficiation and separation technology and its 100% interest in a group of unpatented mining claims and repurchase rights to adjacent private property, together known as the Bear Lodge Property, owned through a wholly owned subsidiary, Rare Element Resources, Inc., a Wyoming corporation.

 SUBSIDIARIES
 We have one direct wholly owned subsidiary, Rare Element Resources, Inc., incorporated in 1997 in the state of Wyoming, USA, formerly known as Paso Rico (USA), Inc. ("Paso Rico"). Rare Element Holdings Ltd., formerly a direct wholly owned subsidiary of ours, was dissolved on August 16, 2023.
 DESCRIPTION OF BUSINESS
 We are focused on demonstrating the technical and economic feasibility of our proprietary processing and separation technology through the permitting and licensing, construction, and operation of a planned Demonstration Plant and advancing the Bear Lodge REE Project located near the town of Sundance in northeast Wyoming. The Bear Lodge REE Project consists of several large, disseminated REE deposits and a planned hydrometallurgical plant to be located near Upton, Wyoming. The Bear Lodge REE Project is one of the highest-grade REE deposits identified in North America containing a favorable distribution of CREE.
 In its development efforts for the Bear Lodge REE Project, the Company has done extensive laboratory bench-scale and pilot plant testing on metallurgical processes to recover saleable rare earth products and has been granted two patents on its metallurgical processing innovations. More specifically, the Company has pilot tested and received patent protection for a method for the removal of thorium from a rare earth element (REE)-containing acidic solution, as well as a method for the selective extraction of REEs from base metals in a pregnant liquid solution.
 Our near-term focus is on the progression of the Demonstration Plant as further described below. Assuming the Demonstration Plant operation is successful, the Company plans to evaluate the feasibility of processing and separating REEs from the Bear Lodge REE Project as well as other sources on a commercial scale.
 During the first quarter of 2016, we placed the Bear Lodge REE Project under care-and-maintenance due to financial resource constraints and market conditions, and all permitting and licensing activities were suspended at that time. Based on current permitting and licensing timetables and other factors, we anticipate that once formally recommenced, we could receive all permits and licenses for the Bear Lodge REE Project approximately 30 to 36 months after resuming permitting and licensing efforts. Commencement of those efforts may be dependent upon our Demonstration Plant's operating results.
 If and when a decision to resume the Bear Lodge REE Project development activities is made, our plan is to advance engineering in preparation for the FS, including an evaluation of a potential step approach to development beginning with a smaller initial production facility utilizing higher-grade material which could then be scaled up. Our ability to begin construction activities on the Bear Lodge REE Project may be subject to various factors including: (i) the availability of adequate capital, (ii) positive results from the Demonstration Plant's operations, (iii) an affirmative FS, (iv) securing off-take agreements with customers at adequate prices, (v) obtaining necessary permits and licenses, and (vi) approval from the Company's board of directors (the "Board of Directors" or the "Board").
 The Bear Lodge REE Project deposit is located near excellent mining infrastructure, including good road access and power lines within two kilometers of the Bear Lodge Property. Geographically, the Bear Lodge Property is located 100 kilometers east of Gillette, Wyoming, a major infrastructure, support, and logistics center for coal mines in the Powder River Basin that should provide for ready access to many of the required production supplies and materials as well as skilled labor. Additionally, the deposit is situated only 64 kilometers from the nearest railhead at Upton, Wyoming, where the Demonstration Plant is sited and the proposed hydrometallurgical plant is planned to be sited, allowing access to major distribution channels via the adjacent railhead as well as convenient access to utilities and other infrastructure.
 Additional information regarding the Bear Lodge REE Project and the Bear Lodge Property is included under the section heading "Item 2. Properties" in this Annual Report.

 RECENT CORPORATE DEVELOPMENTS
 Rare Earth Demonstration Plant Project

 Department of Energy Financial Award

 In January 2021, a consortium of companies, of which the Company is a part, received notice from the DoE that the consortium had been selected for negotiation of a potential financial award for the engineering, construction and operation of a rare earth separation and processing Demonstration Plant. The consortium of companies is led by General Atomics, an affiliate of Synchron, the Company's majority shareholder, and includes certain of General Atomics' affiliates, and LNV, an Ardurra Group, Inc. company, as engineering and construction subcontractor. A formal proposal was submitted by the consortium in response to a published Funding Opportunity Announcement in mid-2020 for the construction and operation of a rare earth separation and processing plant utilizing proprietary technology to produce commercial-grade products. The DoE finalized the award, and an agreement was executed by the DoE's grants/agreement officer on September 27, 2021, with an effective date of October 1, 2021. The Company, as a subrecipient of the award, along with the other consortium members, commenced work on the planning and design of the Demonstration Plant project in November 2021, with the Company's contractual arrangement with General Atomics finalized in December 2021. The DoE funding is in the amount of $21,900 and represents approximately one-half of the originally estimated costs for the Demonstration Plant. The Demonstration Plant will process already stockpiled high-grade mineralized materials from the Bear Lodge REE Project.

 During 2022 and 2023, the Company, along with the other consortium members, progressed work on the Demonstration Plant, and this work is expected to continue through the anticipated completion date of operations in the latter part of 2025. Through December 31, 2023, the Company had paid to General Atomics, as leader of the consortium, a total of $15,700 toward its share of the expected cost of the Demonstration Plant (see Note 4 to the Consolidated Financial Statements for a more complete discussion).
 In late December 2023, the Demonstration Plant project achieved the DoE's second go/no-go decision point, with the first being upon completion of engineering in December 2022. Also, in late December, the Demonstration Plant project received a continuation notice following receipt of the Nuclear Regulatory Commission (the "NRC") Source Material License and the DoE's Finding of No Significant Impact (FONSI) through its National Environmental Policy Act of 1969 ("NEPA") review. The completion of these milestones was a gating event for the DoE's continued sharing of the cost of the Demonstration Plant into construction as provided for in the 2021 financial award. The remaining gating milestone relates to the completion of construction and pre-operational inspections. Operations to process and separate the REEs from the stockpiled sample materials are expected to follow the completion of the Demonstration Plant's construction for an additional 12-to-15-month period.
 Wyoming Energy Authority Financial Award

 In November 2022, the Company received notice that it had been awarded a $4,400 grant from the WEA to be used toward the advancement of the Demonstration Plant, and a funding agreement was finalized in June 2023. The WEA grant is a cost-reimbursement award with payments tied to the achievement of certain predefined Demonstration Plant milestones. As of December 31, 2023, the WEA had been invoiced for the first $2,000 of the $4,400 grant total with the achievement of the first grant milestone, the DoE's continuation notice. The Company received payment of this $2,000 in January 2024. The remaining $2,400, which is conditioned on the achievement of other, future milestones, will be invoiced to the WEA once those milestones have been achieved, currently expected in the third quarter of 2024.
 Future Funding Needs

 As a result of its financing needs, the Company announced on December 5, 2023 its intention to launch a rights offering to raise gross proceeds of approximately $36,000. In March 2024, the Company completed the rights offering for gross proceeds of approximately $35,800 in which each holder of the Company's common shares as of the record date of December 15, 2023 was eligible to participate. Even with the funds raised in the rights offering and the expected receipt of the remainder of the DoE financial support and WEA grant monies, the Company will not have sufficient funds to

 progress certain activities, including the permitting, licensing, development, and construction related to the Bear Lodge REE Project. In the event the Company cannot secure additional financial resources or complete a strategic transaction in the longer term relating to the development of the Bear Lodge REE Project, it may need to suspend its operational plans or even have to liquidate its business interests, and investors may lose all or part of their investment.
 Current External Factors Impacting our Business

 Throughout 2023, we continued to monitor the general U.S. political climate and actions taken by the U.S. government to secure a domestic, rare earth supply chain. The U.S. federal government issued two Presidential Executive Orders in 2017 to encourage and support the establishment of a domestic rare earth supply chain and to strengthen the defense industrial base with respect to critical minerals including rare earths. In June 2019, the Department of Commerce released its report entitled "Federal strategy to ensure secure and reliable supplies of critical minerals." This was followed by four U.S. Presidential Determinations on July 22, 2019, directed to the Secretary of Defense. One Presidential Determination declared that "the domestic production capability for rare earth metals and alloys is essential to the national defense." Since then, four more Presidential Determinations/Waivers have been signed that support the critical mineral industry, which include rare earth elements. The "Supply Chain Resilience (Waiver)" signed February 27, 2023 allows funds to be directed towards industrial base supply chains critical to the Department of Defense, including rare earth mineral extraction, processing, and separation. These initiatives have increased the federal government's level of interest in the rare earth industry and our potential rare earth products as a critical upstream segment of the supply chain, potentially countering China's dominance in the global rare earth market.
 In addition, the impacts of the COVID-19 pandemic and other external influences (such as the Russia/Ukraine war and conflicts in the Middle East) have further focused the U.S. government on the importance of implementing secure domestic supply chains, including for rare earths, leading to a further Presidential Executive Order issued in February 2021 calling for an expedited 100-day review to address the strengthening of America's supply chains, specifically requiring the Department of Defense to (i) submit a report identifying "risks in the supply chain of critical minerals and other strategic materials including rare earth elements" and (ii) make policy recommendations to address the risks. The 100-day review led to another Executive Order on June 8, 2021, calling for an investment in sustainable domestic and international production and processing of critical minerals, including a recommendation that Congress take actions to recapitalize and restore the National Defense Stockpile of critical minerals and materials. The Company monitors and participates in these initiatives as they are critical to the production of rare earth magnets used in the United States to support the manufacturing of, among other things, defense technologies, electric vehicles, wind turbines, consumer electronics, and oil refining equipment. In December 2023, China announced it had banned the export of technology to make rare earth magnets, adding to their previous export ban of critical material extraction and separation technology.
 TRENDS AND DESCRIPTION OF THE REE MARKET
 Uses for REE Products
 Due to variations in physical, chemical, molecular and application characteristics, different rare earth metals possess their own market uses, drivers and challenges. REEs are used in computers, cellular telephones, television screens, wind turbines, fuel cells, automobiles, magnetic refrigeration, energy-efficient lighting, petroleum-refining catalysts, and numerous other modern specialty technologies including military applications. Lately, the major driver for the rare earth metals market has been the increasing consumption in the manufacture of permanent NdFeB rare earth magnets, in which rare earth metals such as Nd, Pr, Tb, and Dy are used. Specifically, these REEs are used in hybrid and electric vehicle motors as well as in wind turbines. Ce, La, and other REEs are widely used in applications such as metallurgy, catalysts, glass, ceramics, optical instruments, and polishing.
 Trends Affecting REE Supply, Demand and Prices
 In 2023, rare earth mine production increased by approximately 8% to 338,000 tonnes TREO relative to 2022 with refined production estimated to be 237,000 tonnes TREO, a 9% increase from 2022. Production from China, Australia, and the U.S. contributed to the increased mine production. Despite the production increases from Australia and the U.S., China still dominates the global supply of rare earths at both the mined and refined stages, accounting for 63% of global mine

 production and 84% of refined production in 2023. China's share of global refining is partly influenced by U.S. production of TREO concentrates which are sent to China.
 In the rest of the world, specifically in the U.S. and Australia, certain competitors form a second tier of rare earth concentrate producing companies, with 45,000 tonnes TREO mine production coming from the U.S. and approximately 46,000 tonnes TREO coming from Australia. A facility in Malaysia produces separated rare earths from TREO mined in Australia.
 The rapid growth in demand for certain REEs, specifically Nd and Pr used in permanent magnets for electric motors and generators, is expected to continue as these magnets give improved performance compared with other magnets. The increased focus on clean energy is driving the demand for wind turbines and electric vehicles, which in turn will drive the demand for rare earth magnets. Magnet demand now accounts for more than 40% of total rare earth demand and greater than 80% of REE market value. Near-term neodymium-praseodymium ("NdPr") oxide prices have trended downward, however, as a result of persistent market surpluses with capacity expansions at Chinese mines having been the largest source of supply growth since 2015. Longer-term, the NdPr price is expected to rise as a supply gap begins to take hold and existing sources of supply become more strained seeking to meet the projected growth in demand.
 The research and advisory firm, Wood Mackenzie Limited ("Wood Mackenzie"), is forecasting that magnet applications, particularly for electric vehicles, and offshore wind energy generation, will continue to increase their share of overall demand for rare earth magnets rising from 48% in 2023 to 54% in 2028. This increase in demand for magnet rare earths, namely Nd-Pr, Dy and Tb oxides, is expected to drive future growth above other rare earth compounds and support higher prices. Vehicle sales have experienced robust growth with every sixth vehicle now having a plug (battery-powered and plug-in hybrid electric vehicles) and every fourth being electrified (battery-powered, hybrid and plug-in hybrid electric vehicles). Global plug-in electric vehicles sales reached 14 million units in 2023, an increase of 35% compared to 2022. During 2023, the annual global demand for rare earth oxides for use in permanent magnets reached 81,600 tonnes TREO, representing 46% of total REE demand. (Source: Wood MacKenzie, Global Rare Earths Short-Term Outlook, Jan. 2024).
 Supply and demand factors for REE products that could positively impact future REE prices include the following, among other factors:

 the use of Nd, Pr, Tb and Dy in high-strength magnets that are critical to multiple defense applications, hybrid and electric vehicles and wind power generation facilities, particularly large off-shore installations;

 the use of high-strength NdFeB magnets in the miniaturization of electronic products;

 the use of La in the fluid catalytic cracking process used by refineries processing lower quality crude oil that consumes greater quantities of the catalysts;

 the increased use of REEs in the drive to reduce global carbon emissions;

 China consolidating its REE industry and closing small, inefficient, and polluting REE producers;

 the capping of production and the tightening of export volumes and imports by China;

 changes in trade policies, including changes in taxes or import/export duties for REE materials by the U.S. government and/or China;

 the use of Ce in glass, ceramics, glass polishing, and advanced water filtration applications;

 the continued research and commercialization of new applications for REE products; and

 the rising costs in China due to stricter environmental controls and rising wages.

 Supply and demand factors for REE products that could negatively impact future REE prices include the following, among other factors:

 the potential for oversupply of certain REEs due to new production inside and outside of China and/or increased exports from China;

 development or enhancements of alternative electric motor or generator technologies that may use less or no REE magnet materials;

 strong demand for selected REEs like magnet materials, driving overproduction of other co-product REEs and creating oversupply conditions for non-magnet REEs;

 the potential substitution of other materials for higher-priced REEs;

 the development of new, lower cost sources of supply that could reduce or eliminate the market for REEs;

 economization by intermediate and end-users to reduce the usage of REEs in end-products;

 the potential for increased recycling of higher-priced REEs;

 fluctuating oil, gas and coal prices that could reduce the demand for technologies using REEs;

 static or lower global economic growth, reducing overall demand growth for REEs; and

 potential by-product production of REEs that may increase supply irrespective of the economics of REE production from primary mines.

 The feasibility of the Bear Lodge REE Project and our ability to raise additional funds to develop the Bear Lodge REE Project may be impacted by global supply and demand and future prices of REEs.
 SEASONALITY
 At this stage, seasonality in the state of Wyoming is not a material factor to any future exploration, development, and operating activities on the Bear Lodge Property. Snowfall in the winter may temporarily limit our access to the Bear Lodge Property, limit work activities on the Demonstration Plant or limit future work on a commercial-scale processing facility from approximately November through June.
 COMPETITION
 The industry in which we operate is highly competitive. We compete with other mining and exploration companies, both within the U.S. and internationally, for the exploration and development of mineral properties and production of REEs as well as funding for projects. There is competition for the limited number of opportunities, some involving companies having substantially greater financial resources, staff, and facilities than we do, and some with rare earth operational experience. We also compete with other mining and exploration companies in our efforts to hire and retain experienced professionals. As a result, we may have difficulty attracting or retaining key personnel or securing outside technical resources.
 In 2023, China accounted for an estimated 63% of global REE mine production and 84% of global refined production. Wood MacKenzie has forecasted that China will remain the primary source of mine supply, although China's share of global mine production is projected to decline to 56% by 2028. China is also expected to remain the largest contributor of refined supply, but China's share of total refined production is projected to decrease to 70% by 2027. In similar fashion, demand will remain Asia driven, with China maintaining a dominant position. This gives the Chinese producers a continued competitive advantage in controlling the supply and processing of REEs and an opportunity to influence prices to discourage competition. Additionally, any increases in the quantities of REEs exported from other nations will likely only increase supply and may result in price reductions, reduced margins, and loss of potential market share, any of which could materially adversely affect our business. As a result of these factors, the Company may not be able to compete effectively against current and future competitors. See "Item 1A. Risk Factors" of this Annual Report.
 PATENTS, TRADEMARKS AND LICENSES
 We rely on a combination of trade secret protection, nondisclosure agreements, trademarks, and patents to establish and protect our proprietary intellectual property rights in our rare earth technology.
 As of December 31, 2023, we had on file U.S. provisional patent applications relating to processing methods, including (1) selective recovery of REEs from mixed chloride leach solutions using oxalic acid, and (2) separation of thorium from bulk REEs in a solvent extraction ("SX") process. These provisional applications provided the basis for the current patent portfolio, which includes two issued U.S. patents and one pending U.S. divisional patent application, and fifteen issued foreign patents across thirteen foreign jurisdictions. The issued U.S. patents have a term of 20 years measured from the filing date of the utility patent applications. We licensed our intellectual property, including patents and related technical

 information, to our majority shareholder, Synchron, in October 2017, and the license became exclusive to Synchron and its affiliates in October 2019. The Company retains a limited right to use its intellectual property and any enhancements thereto. See "Item 1A. Risk Factors" of this Annual Report. Several of these technologies have potential value for application in other industries.
 ENVIRONMENTAL REGULATION
 Our exploration and planned development, mining and processing activities are subject to extensive and demanding environmental laws and regulations under various federal, state, county and local laws relating to the protection of the environment, which generally includes air and water quality, hazardous waste management, radionuclide handling and reclamation. Failure to comply with these requirements can result in civil and/or criminal liability for non-compliance and governmental fines and penalties. Also, developments or changes in the law could require us to make environmental expenditures significantly greater than those we currently expect that could materially or adversely affect us. Environmental laws historically have evolved in a manner that requires stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects and a heightened degree of responsibility for companies and their officers, directors, and employees. Current and future laws, regulations and permits will impose significant costs, liabilities or obligations or could limit or prevent our ability to continue operations or undertake new operations. A future change in the U.S. presidential administration or in the composition of the Congress could result in more stringent environmental regulation of our operations. In addition, under various federal, state and local laws and regulations, a current or former owner or operator of a property may be liable for the cost to remove or remediate contamination resulting from the presence or discharge of hazardous or toxic substances, wastes or products on, under or from such property. Costs to address contamination can be substantial and liability under such laws may attach without regard to whether the owner or operator caused or was responsible for such contamination, and the liability may be joint and several. Moreover, the presence of contamination could expose us to third-party liability (e.g., for cleanup costs, bodily injury or property damage), subject our properties to liens in favor of the government, impose restrictions on the manner in which a property may be used, or materially or adversely affect our ability to sell, lease or develop properties.
 Our Bear Lodge Property in Wyoming is subject to federal and state environmental laws, regulations, and permits. The federal agency with primary regulatory jurisdiction is the U.S. Forest Service (the "USFS"), Bear Lodge Ranger District, Sundance, Wyoming. The state agency with regulatory jurisdiction is the Wyoming Department of Environmental Quality (the "WDEQ"). We operate under approvals and permits granted by these two agencies and have established a surety bond to ensure environmental reclamation of areas disturbed. As of December 31, 2023, the Company holds surety bonds with the state of Wyoming totaling $182. Prior to operating, we will require several other permits and licenses including those issued by the NRC, U.S. Army Corps of Engineers, and others.
 Our Demonstration Plant is subject to federal, state, county and local licenses and permits, including an NRC source material possession license, USFS road use permit and WDEQ air quality and storm water permits, among others. As of December 31, 2023, the Company held a surety bond, totaling $917, with the state of Wyoming for the reclamation of the Demonstration Plant.
 MINERALS EXPLORATION REGULATION
 Mining operations and exploration and development activities are subject to various national, state, county and local laws and regulations in the U.S. that govern prospecting, exploration, development, mining, production, processing, exports, taxes, labor standards, occupational health, waste disposal, protection of the environment, mine safety, hazardous substances, and other matters. The Company believes that it is in compliance in all material respects with applicable mining, health, safety and environmental statutes and regulations. There are no current orders or notices of violations relating to the Company under applicable laws and regulations.
 Compliance with these laws and regulations may impose substantial costs on the Company and could subject it to significant potential liabilities. Changes in these laws or regulations could require us to expend significant resources to comply with new laws or regulations, or changes to current requirements, and could have a material adverse effect on our business operations.

 MINE SAFETY AND HEALTH REGULATIONS
 Pursuant to Section 1503(a) of the Dodd–Frank Wall Street Reform and Consumer Protection Act (the "Dodd–Frank Act"), issuers that are operators, or that have a subsidiary that is an operator, of a coal or other mine in the U.S. are required to disclose in their periodic reports filed with the SEC information regarding specified health and safety violations, orders and citations, related assessments and legal actions, and mining-related fatalities. During the year ended December 31, 2023, our Bear Lodge Property was not subject to regulation by the federal Mine Safety and Health Administration under the Federal Mine Safety and Health Act of 1977.
 EMPLOYEES
 At December 31, 2023, we had two full-time employees and no part-time employees. Our employees are not covered by any collective bargaining agreements. When required, our employees will engage the services of third parties under consulting or service agreements.
 AVAILABLE INFORMATION

 ITEM 1A. RISK FACTORS
 The following sets forth certain risks and uncertainties that could have a material adverse effect on our business, financial condition and/or results of operations and the trading price of our common shares, which may decline, and investors may lose all or part of their investment. Additional risks and uncertainties that we do not presently know or that we currently deem immaterial may also impair our business operations. We cannot assure you that we will successfully address these risks. Our risk factors are grouped into the following categories:

 Risks Related to Our Business;

 Risks Related to the Mineral Exploration, Development, Mining and Processing Industries;

 Risks Related to Our Common Stock; and

 General Risk Factors.

 Risks Related to Our Business
 We may not be able to complete our Demonstration Plant project.
 The approved DoE schedule has one remaining go/no-go decision point prior to the start of operations. Should the project team and/or the DoE determine not to continue with the project, funding would be halted, and the project would be terminated or delayed, which could have a material adverse effect on our development and operations plans.

 Current inflationary conditions may adversely impact the ability to complete the Demonstration Plant construction and operations.
 We are subject to the impact of inflation on wages, capital equipment, general supplies and reagents in the construction and operation of our Demonstration Plant that are expected to require supplemental funding or a change in scope of the planned operation. If such supplemental funding need is in excess of our financial resources, including the proceeds from the March 2024 rights offering, and further funding cannot be secured, the Demonstration Plant may not be able to operate for a sufficient amount of time, or its scope could be reduced, either of which could adversely impact the intended results.
 We have no revenues from operations and expect to incur losses for a significant period of time. Any future revenues and profits are uncertain.
 We have incurred losses since our inception, and further losses are anticipated in the development of our business. As of December 31, 2023, we had cash and cash equivalents of $3,633. During the year ended December 31, 2023, we consumed cash of $11,706.
 We announced, on December 5, 2023, our intention to launch a rights offering to raise approximately $36,000 in gross proceeds. In March 2024, the Company completed the rights offering for gross proceeds of approximately $35,800 in which each holder of the Company's common shares as of the record date of December 15, 2023 was eligible to participate. Even with the funds raised in the March 2024 rights offering and the expected receipt of the additional $2,400 grant monies from the WEA, we will not have sufficient funds to progress our longer-term activities, including the permitting, licensing, development, and construction related to the Bear Lodge REE Project. Therefore, the achievement of these activities will be dependent upon the receipt of additional funds through financings, off-take agreements, joint ventures, strategic transactions, or sales of various assets. Ultimately, in the event that we cannot secure additional financial resources, or complete a strategic transaction in the longer term, we may need to suspend our operational plans or even have to liquidate our business interests, and investors may lose all or part of their investment.
 Our largest shareholder beneficially owns a majority of our common shares, has significant influence on, and control over the outcome of, our major corporate decisions, including veto power over some matters, and could take actions that may not be viewed favorably by certain other shareholders, any of which actions could adversely affect the market price of our common shares.
 As of March 14, 2024, Synchron owned approximately 70.6% of the issued and outstanding common shares of the Company. Additionally, Synchron has approval rights for certain corporate actions and the right to nominate three of seven directors to the Company's Board. Pursuant to the investment agreement, dated October 2, 2017, by and between the Company and Synchron ("the Investment Agreement"), Synchron has significant influence on, and control over the outcome of, certain of our major corporate decisions and matters requiring shareholder approval, including the election of directors, mergers, consolidations and acquisitions, the sale of all or substantially all of our assets and other decisions affecting our capital structure, the amendment of our certificate of incorporation and articles, and our winding up and dissolution. These rights, along with the concentration of ownership and voting power with Synchron, (i) may make it more difficult for any other holder or group of holders of our common shares to significantly influence the way we are managed or the direction of our business and (ii) may make it more difficult for another company to acquire us and for shareholders to receive any related takeover premium unless Synchron approves the acquisition. The interests of Synchron with respect to matters potentially or actually involving or affecting us, such as future acquisitions, financings, and other corporate opportunities, and attempts to acquire us, may conflict with the interests of our other shareholders.
 By granting a license in our intellectual property rights, we may be limited in our ability to protect our intellectual property rights, which could adversely impact our competitive position or results of operations.
 On October 2, 2017, we entered into an Intellectual Property Rights Agreement with Synchron pursuant to which Synchron and its affiliates were granted certain perpetual rights to the intellectual property of the Company relating to its rare earths' patents and related technical information. Upon the exercise of its option on October 16, 2019, Synchron and its affiliates' intellectual property rights became exclusive, subject to the Company's ownership and limited use rights in the intellectual property and any improvements made thereon. As a result of the Intellectual Property Rights Agreement, we may be forced

 to enforce or defend our intellectual property rights against infringement and unauthorized use, and to protect our trade secrets. Further, by granting a license to use our intellectual property, we may be limited in our ability to protect our intellectual property rights by legal recourse or otherwise. In defending our intellectual property rights, we may place our intellectual property at risk of being invalidated, held unenforceable, narrowed in scope, or otherwise limited, any of which could have a material adverse effect on our business and financial condition. Our inability to preserve or maintain an interest in certain intellectual property rights could adversely impact our competitive position or results of operations.
 We have suspended our federal and state licensing, permitting progression for our Bear Lodge REE Project, and there is a risk to the resumption of those efforts in a timely and cost-effective manner.
 During the first quarter of 2016, we placed the Bear Lodge REE Project on care-and-maintenance, and all licensing and permitting activities were suspended, including the environmental impact statement ("EIS") process, state permitting, and the NRC licensing process. The Company continued to hold the Bear Lodge REE Project on care-and-maintenance through 2023. In 2024, we plan to resume certain of these activities, including certain environmental data collection and technical report updates. However, our ability to obtain further financing to fund the full permitting and development of the Bear Lodge REE Project beyond what is allowed by the funds raised in the March 2024 rights offering is uncertain.
 Our ability and timing to exercise our right to purchase certain non-mineral lands for stockpile storage and processing operations is uncertain.
 Our current plan of operations for the Bear Lodge REE Project includes a waste rock storage site located on private property adjacent to the planned mine. This private property consists of 640 acres and was sold to a third party on October 26, 2016. Although we hold a repurchase option on the property until October 2024, our ability and the timing of our exercise of the repurchase option is uncertain. If we were unable to repurchase the property, we would have to update our planned operations to identify an alternative waste rock storage area. Additionally, we hold a land purchase option on private property located in Upton, Wyoming, which is the location for our planned processing operations. If we are unable to maintain or exercise the purchase option, we would have to locate and secure another site as a suitable rare earth processing location.
 We have no history of producing mineral products from our properties.
 We have no history of mining, recovering, or refining any mineral products, and our Bear Lodge REE Project is not in development or production. There can be no assurance that the Bear Lodge REE Project will be successfully developed and placed into production, produce minerals or products in commercial quantities or otherwise generate operating earnings. Advancing properties from the exploration stage into development and commercial production requires significant capital and time and will be subject to further feasibility studies, permitting and licensing requirements and construction of the mine, processing plants, roads and related works and infrastructure. We will continue to incur losses until such time, if ever, when our mining activities successfully reach commercial production levels and generate sufficient revenue to fund continuing operations. There is no certainty that we will produce revenue from any source, operate profitably, or provide a return on investment in the future. If we are unable to generate revenues or profits, our shareholders might not be able to realize returns on their investment in our common shares.
 The planned development of our Bear Lodge REE Project involves numerous uncertainties that could affect the feasibility or profitability of the project.
 Mine development projects typically require a number of years and significant expenditures during the exploration and development phases before production is possible. The economic feasibility of exploration and development projects is based on many factors, such as the following:

 completion of feasibility studies to evaluate mineral resources and mineral reserves and commercial viability;

 the timing and cost, which can be considerable, of further exploration, licensing, permitting and construction of infrastructure, mining, processing and/or beneficiation facilities;

 our ability to utilize our proprietary process technologies, which could encounter problems or unexpected costs in scale-up;

 securing commercially viable sales outlets for our REE products;

 the potential need to enter into joint venture or other partnership arrangements to develop the Projects;

 the availability and costs of equipment, supplies and skilled labor, as required;

 the availability and cost of appropriate processing and/or refining arrangements, if required;

 compliance with environmental and other governmental approval and permit requirements;

 the availability of funds to finance exploration, development, and construction activities, as warranted;

 future prices for rare earth minerals;

 potential opposition from non-governmental organizations, environmental, indigenous, or local groups or inhabitants that may delay or prevent development activities;

 potential increases in exploration, construction, and operating costs due to changes in the cost of labor, fuel, power, materials, or supplies;

 potential shortages of mineral processing and/or beneficiation, construction or other facilities-related equipment or supplies; and

 the ability to attract and retain talent for development and operation of the Bear Lodge REE Project.

 It is common in exploration programs and in development, construction, and mine start-ups to experience unplanned problems and delays. Accordingly, our activities may not result in profitable mining operations, and we may not succeed in establishing mining operations or profitably producing minerals from our Projects at all or in a reasonable timeframe.
 Joint ventures and other partnerships may expose us to risks.
 We will require additional capital through investment, joint ventures and/or other partnership arrangements with current investors or other parties for the development of our Projects. Although such arrangements may lessen our financial burden in exploring and developing the Projects, they will likely also dilute our interest therein or affect our ability to control development of any of the Projects. Our ability to attract additional capital may be limited by our majority shareholder Synchron, as it holds certain contractual approval rights pursuant to the Investment Agreement, and its approval may be required. In addition, Synchron has significant influence on, or the ability to control the outcome of, certain of our major corporate decisions and matters requiring shareholder approval. Any failure of a joint venture partner or other partner to meet its obligations to us or to third parties, or any disputes with respect to the parties' respective rights and obligations, could have a material adverse effect on the joint venture or other partnership arrangement and, in turn, on our business performance and on our ability to develop the Projects.
 Subject to further financing, and progression and outcome of the Demonstration Plant, we may commence a FS on our Bear Lodge REE Project, and the results of this FS are uncertain.
 In October 2014, we completed a PFS for our Bear Lodge REE Project that updated our mineral resource estimate and refined plans for our process technology. We subsequently updated the mineral resource and completed a TRS in 2024 (See "Item 2. Properties" of this Annual Report) and are in the process of completing an NI 43-101 compliance technical report for the Bear Lodge REE Project; however, the economic assessment of the Bear Lodge REE Project has not been progressed through an updated FS. Subject to further financing and the results of the Demonstration Plant, we may resume work on an FS. Whether the Company undertakes a FS in the future and, if so, the results of any such study, are uncertain and may indicate project economics that are more or less favorable than those previously reported in 2014 or in the TRS. As our project optimization efforts continue, we cannot ensure that the FS will be based upon all of the same inputs used in the PFS and TRS. As a result, we may need to update our processing and/or beneficiation technology, and/or project development plans to enhance economics or further study aspects of the Bear Lodge REE Project. This could result in significant additional delays and expenses or could make financing efforts with respect to such efforts more difficult or not possible. In addition, there is a risk that the Company may not resume work on a FS.
 Our viability as a rare earth company depends, in large part, on the financing, licensing, permitting, development and operation of our Bear Lodge REE Project, which is our only rare earth project.
 Our only rare earth project at this time is the Bear Lodge REE Project. Our continued viability is based, in large part, on successfully implementing our strategy, including completion of a FS, licensing, permitting and construction of a mine

 and processing and/or beneficiation facilities in a reasonable timeframe. If we are unable to secure additional capital or enter into a strategic transaction and implement our strategy, or in the event of the imposition of significant additional regulatory burdens or delays or a significant deterioration of the market for rare earth products, our ability to develop a sustainable or profitable business would be materially adversely affected. If the Bear Lodge REE Project does not proceed, then the viability of the Company may depend upon the ability to process REE from sources other than our Bear Lodge REE Project using our proprietary technology assuming the technology is successfully proven through the operation of the Demonstration Plant.
 Increased costs could affect our ability to bring the Bear Lodge REE Project into production and, once in production, to be profitable.
 We estimated the initial capital costs required to bring the Bear Lodge REE Project into commercial production in our historical PFS, dated October 9, 2014, at approximately $290,000. We did not evaluate the capital cost estimates in our TRS for the Bear Lodge REE Project. Our FS, if and when completed, could suggest that our estimated costs may be materially higher than those we previously anticipated, which could make it more difficult to finance the Bear Lodge REE Project or to successfully establish mining operations.
 We anticipate that our future operating costs at the Bear Lodge REE Project will vary from year to year due to a number of factors, such as changing grade, metallurgy, and revisions to mine plans in response to the physical shape and location of the ore body. In addition, costs are affected by the price of commodities such as oil, gas, reagents/chemicals, steel, rubber, and electricity. Such commodities are at times subject to volatile price movements, including increases that could make production less profitable or not profitable at all. A material increase in costs could also impact our ability to commence or maintain future development of mining operations.
 A future pandemic may have an adverse impact on our business.
 A future pandemic or similar public health issues, as seen in the COVID-19 pandemic, could have a material adverse effect on our ability to raise capital, construct or operate our Demonstration Plant, mine, or production facility, or execute our business plans. In addition, preventive measures we may voluntarily put in place may have a material adverse effect on our business for an indefinite period of time, such as decreased employee or contractor availability, unavailability of needed products or services, or disruptions to the businesses of our contracted service providers and others. Our suppliers may also face these and other challenges, which could lead to a disruption or delay in their services. Any pandemic and resulting economic slowdown may also impact the supply and demand for rare earths domestically and globally. Although these disruptions may continue to occur, the long-term economic impact and near-term financial impacts of a pandemic, its ongoing variants, and other possible public health threats cannot be reasonably estimated at this time due to the uncertainty of future developments.
 We expect to rely on our proprietary technology and processes to further our Bear Lodge REE Project.
 We rely on a combination of trade secret protection, nondisclosure agreements, trademarks, and patents to establish and protect our proprietary intellectual property rights in our rare earth technology. As of December 31, 2023, we had on file U.S. provisional patent applications relating to processing methods, including (i) selective recovery of REEs from mixed chloride leach solutions using oxalic acid, and (ii) separation of thorium from bulk REEs in a solvent extraction ("SX") process. These provisional applications provided the basis for the current patent portfolio, which includes two issued U.S. patents and one pending U.S. divisional patent application, and fifteen issued foreign patents across thirteen foreign jurisdictions. The issued U.S. patents have a term of 20 years measured from the filing date of the utility patent applications. We licensed our intellectual property, including patents and related technical information, to Synchron in October 2017, and the license became exclusive to Synchron and its affiliates in October 2019. See "Item 1A. Risk Factors" of this Annual Report. Several of these technologies have potential value for application in other industries, and the Company is evaluating this potential. The success of our business depends, in part, on our ability to utilize our proprietary process technologies, and we could encounter unforeseen problems or costs, or both, in scaling up our technologies to commercial applications.

 Our mineral resource estimate may be inaccurate and any material change in this estimate could affect the viability of placing our property into production.
 In March 2024, the Company announced the completion of a new mineral resource estimate based on maximizing the recovery of lanthanum (La) and the key magnet materials of neodymium (Nd), praseodymium (Pr), terbium (Tb), and dysprosium (Dy). The estimate was focused on the Bull Hill deposit at the Bear Lodge REE Project with long-term upside existing in the Carbon, Whitetail, and Taylor deposits. Unless otherwise indicated, our mineral resources are based upon estimates made by independent geologists. When making determinations about whether to advance the Bear Lodge REE Project to development, we must rely upon such estimated calculations as to the quantity and grades of mineralization contained in the property. Until mineralized material is actually mined and processed, mineral resources and grades of such mineralization must be considered estimates only, which may prove to be unreliable. Because we have not completed a FS on the Bear Lodge REE Project and have not commenced actual production, the mineral resource estimate for the Bear Lodge REE Project may require adjustments or downward revisions. In addition, the grade of material ultimately mined, if any, may differ from that indicated in our mineral resource estimate or in future feasibility studies. Our mineral resource estimate has been determined based on assumed cut-off grades that depend upon estimated REE prices and recovery rates. Any significant increase in cut-off grades could reduce our estimates of mineralization, or the amount of mineralization to be extracted, and could have a material adverse effect on our share price and the value of our Bear Lodge REE Project.
 The historical mineral resource estimates for our Projects are not considered current, need to be updated, and should not be relied upon.
 The 2014 and 2011 historical mineral resource estimates for our Projects have not been fully updated and, as such, should not be relied upon as they may be updated prior to further feasibility work. Furthermore, the TRS of 2024 did not evaluate the economics of the Bear Lodge REE Project or capital requirements. Accordingly, the previous mineral resource estimates from 2014 and 2011 for the Bear Lodge REE Project and the Sundance Gold Project, respectively, will require further updating and should not be relied upon. The Bear Lodge REE Project has been under care-and-maintenance since 2016, and the Sundance Gold Project is in the early exploration stage and has been on hold since 2014. Additionally, it is too early to estimate resources or the gold production potential of the Sundance Gold Project. We have not done sufficient work to classify the historical mineral estimates for our Projects as current estimates of mineral resources, and we are not treating the historical mineral estimates as current estimates of mineral resources.
 We depend on key personnel, and the absence of any of these individuals could adversely affect our business.
 Our success is currently largely dependent on the performance, retention and abilities of our directors, President and Chief Executive Officer ("CEO"), Chief Financial Officer ("CFO") and certain consultants. The loss of the services of these persons could have a material adverse effect on our business and prospects. On January 2, 2024, Mr. Berg notified the Company of his decision to resign as the President and Chief Executive Officer and as a director of the Company, in each case effective as of April 2, 2024, unless sooner terminated by the Company. On March 14, 2024, the Company and Mr. Berg agreed that such resignations would take effect on March 20, 2024. Also on March 14, 2024, the Board appointed (i) Kelli Kast, a current director of the Company, as the interim President and Chief Executive Officer of the Company, in each case effective as of March 20, 2024, and (ii) Kenneth Mushinski as the President and Chief Executive Officer and as a director of the Company, in each case effective as of May 1, 2024. There is no assurance that we can maintain the services of our directors, CEO, CFO, or other qualified personnel and consultants required to operate our business. Failure to do so could have a material adverse effect on us and our prospects. We do not maintain life insurance policies on our employees, directors, or consultants.
 U.S. investors may not be able to enforce their civil liabilities against us or our directors, controlling persons and officers.
 It may be difficult to bring and enforce suits against us. We are incorporated in the province of British Columbia, Canada under the BCBCA. Some of our directors may be residents of Canada, and a substantial portion of their assets are located outside of the U.S. As a result, it may be difficult for U.S. holders of our common shares to effect service of process on these persons within the U.S. or to recover in the U.S. on judgments rendered against them. In addition, a shareholder

 should not assume that the courts of Canada (i) would enforce judgments of U.S. courts obtained in actions against us or such persons predicated upon the civil liability provisions of the U.S. federal securities laws or other laws of the U.S., or (ii) would enforce, in original actions, liabilities against us or such persons predicated upon the U.S. federal securities laws or other laws of the U.S.
 We believe that we were a "passive foreign investment company" ("PFIC") for the year ended December 31, 2023, and could be a PFIC in subsequent years, which could have adverse U.S. federal income tax consequences for U.S. shareholders.
 An investor in our common shares that is a U.S. taxpayer (referred to as a U.S. shareholder) should be aware that we believe that we were a PFIC for the year ended December 31, 2023. We also expect that we will be a PFIC for the year ending December 31, 2024 and that we may be a PFIC in subsequent years. The tests for determining PFIC status are dependent upon a number of factors, some of which are beyond our control and can be subject to uncertainties. Accordingly, we cannot provide certainty that we were or were not a PFIC for the year ended December 31, 2023, or that we will or will not be a PFIC for the year ending December 31, 2024, or for any future year. We will use commercially reasonable efforts to provide information regarding our status as a PFIC, and the PFIC status of any subsidiary in which the Company owns more than 50% of such subsidiary's total aggregate voting power, to U.S. shareholders who make a written request for such information. Adverse rules apply to U.S. shareholders who own our common shares if we are a PFIC. Each U.S. shareholder should consult its own tax advisor regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, and U.S. state and local tax consequences of the PFIC rules and the acquisition, ownership, and disposition of our common shares if we are or become a PFIC. For additional information regarding PFIC tax consequences, see "Part II, Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities—Certain U.S. Federal Income Tax Considerations—Passive Foreign Investment Company Rules."
 Risks Related to the Mineral Exploration, Development and Mining Industries
 We may be adversely affected by fluctuations in demand for, and prices of, rare earth products.
 Because our primary focus currently is the advancement and development of a Demonstration Plant and ultimately the Bear Lodge REE Project, changes in demand for, and the market price of, REE products could significantly affect our ability to develop or finance the Bear Lodge REE Project, and eventually attain commercial production or profitability. REE product prices may fluctuate and are affected by numerous factors beyond our control such as interest rates, exchange rates, inflation or deflation, fluctuation in the relative value of the U.S. dollar against foreign currencies on the world market, global and regional supply, and demand for REE products, and the political and economic conditions of countries that produce and use REEs. Protracted periods of low prices for REE products could significantly reduce our ability to develop the Bear Lodge REE Project and, if we attain commercial production, to maintain profitable operations.
 Demand for REE products is impacted by demand for downstream products incorporating rare earths, including hybrid and electric vehicles, wind power equipment and other clean technology products, as well as demand in the general automotive and electronics industries. Lack of growth in these markets or the introduction of substitute products could adversely affect the demand for REE products, which would have a material adverse effect on our Bear Lodge REE Project and our business. In contrast, periods of high REE prices are generally beneficial to us; however, strong REE prices, as well as real or perceived disruptions in the supply of REE, also create economic pressure to identify or create non-REE alternate technologies that ultimately could reduce future long-term demand for REE products, and at the same time, may incentivize the development of otherwise marginal mining properties or the development of new, lower cost sources of supply that could reduce or eliminate the market for REEs altogether. For example, automobile manufacturers have announced plans to develop motors for electric and hybrid cars that do not require REE products due to concerns about the available supply of REEs. If the automobile industry or other industries reduce their reliance on rare earth products, the resulting change in demand could have a material adverse effect on our business. In particular, if prices or demand for REEs were to decline, our share price would likely decline, and this could also impair our ability to obtain the funding needed for our operations and our ability to find purchasers for our products at prices acceptable to us or at all.

 An increase in the global supply of rare earth products, dumping and/or predatory pricing by our competitors may materially adversely affect our ability to raise capital, develop our Bear Lodge REE Project or operate profitably.
 The pricing and demand for REE products is affected by a number of factors beyond our control, including growth of economic development and the global supply and demand for REE products. REE supply markets continue to be dominated by production from China, which produced an estimated 63% of the global REE mine production and 84% of refined product in 2023. China also dominates the manufacture of metals, NdFeB magnets and other products from REEs. The threat of increased competition may lead our competitors to engage in predatory pricing behavior or manipulation of the available supply of REEs. Advanced technology in recycling REEs may also impact supply and prices. Any increase in the amount of REE products exported from other nations and increased competition may result in price reductions, reduced margins, or loss of potential market share, any of which could materially adversely affect our business. As a result of these factors, we may not be able to compete effectively against our future competitors.
 The success of our business may depend, in part, on the establishment of new uses and markets for rare earth products.
 The success of our business may depend, in part, on the establishment of new markets by us or third parties for certain rare earth products. Although we plan to produce rare earth products for use in end-products such as NdFeB magnets, which are used in critical existing and emerging technologies (hybrid and electric vehicles, wind power turbines, oil refining catalysts and compact fluorescent lighting), the success of our business may depend on the creation of new markets in addition to the successful commercialization of REE products in existing and emerging markets. Any unexpected costs or delays in the commercialization of any of the foregoing products or applications could have a material adverse effect on our ability to develop our Bear Lodge REE Project or operate our business profitably.
 We are subject to significant governmental regulations, including permitting, licensing and approval processes, that affect our operations and could impact the cost and timing of conducting our business.
 Our current and future activities will be governed by laws and regulations, including the following, among others:

 laws and regulations governing mineral concession acquisition, prospecting, development, mining, processing, production, and decommissioning;

 laws and regulations related to exports, taxes, and fees;

 labor standards and regulations related to occupational health and mine safety;

 laws and regulations relating to environmental protections concerning, among other things, waste management, transportation, and disposal of toxic and radioactive substances, land use, water, air, and the protection of threatened and endangered species.

 We believe that we hold, or are in the process of obtaining, all licenses and permits necessary to carry on the activities that we currently are conducting or propose to conduct in the near term under applicable laws and regulations. Such licenses and permits are subject to changes in regulations and changes in various operating circumstances. There can be no guarantee that we will be able to obtain all necessary licenses and permits that may be required to maintain the current or planned exploration, development and mining activities, including constructing mines and/or processing and/or beneficiation facilities, and commencing operations at the Bear Lodge REE Project. In addition, if we proceed to production on the Bear Lodge REE Project, we will be required to obtain and comply with permits and licenses that may contain specific operating or other conditions. There can be no assurance that we will be able to obtain such permits and licenses or that we will be able to comply with any such conditions. Our Sundance Gold Project, previously in the exploration stage, but on hold since 2014, does not have any of the permits or licenses that would be necessary to carry on further activities on the project. Costs related to applying for and obtaining permits and licenses may be prohibitive and could delay planned exploration and development activities. Failure to comply with applicable laws, regulations and permitting and licensing requirements may result in enforcement actions, including orders issued by regulatory or judicial authorities causing operations to cease or be curtailed, and may include corrective measures requiring capital expenditures, installation of additional equipment or remedial actions.
 Parties engaged in mining operations may be required to compensate those suffering loss or damage relating to mining activities and may be subject to civil or criminal liability, fines or penalties imposed for violations of applicable laws or

 regulations. Amendments to current laws, regulations and permits governing operations and activities of mining companies, or more stringent implementation thereof, could have a material adverse impact on our operations, cause increases in capital expenditures or production costs, or require abandonment or delays in the exploration or the development of either of our Projects.
 Our activities are subject to environmental risks and compliance with environmental laws and regulations that are increasing and costly.
 Our business is subject to environmental regulation in the jurisdictions in which we operate. Environmental laws and regulations at the local, state, and federal level could evolve in a manner that may impose stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects, and a heightened degree of responsibility for companies and their officers, directors, and employees. These laws address, among other issues, emissions into the air, discharges into water, management of waste and hazardous substances, protection of natural resources, antiquities, endangered species, and reclamation of lands disturbed by mining operations. Compliance with environmental laws and regulations at the local, state, and federal level and future changes in these laws and regulations may require significant capital outlays and may cause material changes or delays in our current and planned operations and future activities. It is possible that future changes in these laws or regulations could have a significant adverse impact on our Projects or some portion of our business, causing us to reevaluate those activities at that time.
 Examples of some of the current U.S. federal laws that may affect our business and planned operations include, but are not limited to, the following:

 NEPA requires federal agencies to integrate environmental considerations into their decision-making processes by evaluating the environmental impacts of proposed actions, including issuance of permits to mining facilities, and assessing alternatives to those actions. Under NEPA, a federal agency must prepare an EIS detailing the environmental impacts of "major federal actions significantly affecting the quality of the human environment." The EPA will, and other federal agencies and any interested third parties can, review and comment on the scope of an EIS and the adequacy of and findings set forth in a draft and final EIS.

 We began, in 2012, to undertake the NEPA process for the Bear Lodge REE Project. However, in 2016, we placed the Bear Lodge REE Project under care-and-maintenance, and all permitting and licensing activities were suspended, including the EIS process. The NEPA process can cause delays in issuance of required permits or result in changes to a project to mitigate potential environmental impacts, which in turn can impact the economic feasibility of a proposed project, including the ability to construct or operate the Bear Lodge REE Project or other projects entirely.

 The NRC, pursuant to its authority under the Atomic Energy Act of 1954, as amended (the "Atomic Energy Act"), oversees the regulatory framework governing the control of radioactive materials, including processing and/or beneficiation of REE that contain radioactive source materials such as uranium and thorium. The NRC is responsible for issuing licenses for source material involving concentrations of uranium or thorium that exceed 0.05% by weight. If a proposed action, including waste generation, results in materials with concentrations of uranium and thorium that equal or exceed 0.05% by weight, a license to receive title to, possess, use, transfer, or deliver source and byproduct materials may be required. As our operations are expected to exceed this concentration, we are required to follow the regulations pertaining to a license application for the Demonstration Plant project and the Bear Lodge REE Project. The Demonstration Plant project received the necessary NRC license in the third quarter of 2023. The licensing process, including NEPA review relating to the NRC licensing, when initiated for the Bear Lodge REE Project may cause delays or result in changes to the Bear Lodge REE Project design to mitigate impacts as required under the license.

 Under the Comprehensive Environmental Response, Compensation, and Liability Act, as amended ("CERCLA") and similar state laws, responsibility for the entire cost of cleanup of a contaminated site, as well as natural resource damages, can be imposed upon current or former site owners or operators, or upon any party who released one or more designated "hazardous substances" at the site, regardless of the lawfulness of the original activities that led to the contamination or whether the owner or operator caused or knew of the release. CERCLA also authorizes the EPA and, in some cases, third parties to take actions in response to threats to public health or the environment and to seek to recover from the potentially responsible parties the costs of such actions. We may also be an owner or operator of facilities at which hazardous substances have been released by previous owners

 or operators. We may be responsible under CERCLA for all or part of the costs of cleaning up facilities at which such substances have been released and for natural resource damages. We have not, to our knowledge, been identified as a potentially responsible party under CERCLA, nor are we aware of any prior owners or operators of our properties that have been so identified with respect to their ownership or operation of those properties.

 The Resource Conservation and Recovery Act, as amended ("RCRA"), and comparable state statutes, regulate the generation, transportation, treatment, storage, and disposal of "solid" and "hazardous" waste and authorize the imposition of substantial fines and penalties for noncompliance, as well as requirements for corrective actions. Although certain mining, mineral processing and/or beneficiation wastes currently are exempt from regulation as hazardous wastes under RCRA, the EPA has limited the disposal options for certain wastes designated as hazardous wastes under RCRA. It is possible that certain wastes generated by our potential future operations that currently are exempt from regulation may in the future be designated as hazardous wastes and may therefore become subject to more rigorous and costly management, disposal, and clean-up requirements.

 The Clean Air Act, as amended ("CAA"), and comparable state statutes, restricts the emission of air pollutants from many stationary and mobile sources, including mining, processing and/or beneficiation activities. Our planned mining operations may produce air emissions, including fugitive dust and other air pollutants, from stationary equipment, storage facilities, and the use of mobile sources such as trucks and heavy construction equipment that are subject to review, monitoring, control requirements and emission limits under the CAA and state air quality laws. New facilities may be required to obtain permits before work can begin, and existing facilities may be required to incur capital costs to remain in compliance. In addition, permitting and licensing rules and issued permits may impose limitations on production levels or result in additional capital expenditures to comply with such rules or permits. In certain circumstances, private citizens may also sue sources of pollutants for alleged violations of the CAA.

 The Clean Water Act, as amended ("CWA"), and comparable state statutes impose restrictions and controls on the discharge of pollutants into waters of the U.S. The discharge of pollutants into regulated waters is prohibited, except in accordance with the terms of a permit issued by the EPA or an analogous state agency. These controls generally have become more stringent over time, and it is possible that additional restrictions will be imposed in the future. Violation of the CWA and similar state regulatory programs can result in civil, criminal, and administrative penalties for unauthorized discharges of hazardous substances and other pollutants. They also can impose substantial liability for the costs of removal or remediation associated with such discharges. The CWA also requires a discharge permit for certain activities and requires the implementation of a Pollution Prevention Plan establishing best management practices, training, periodic monitoring of covered activities, and monitoring and sampling of stormwater run-off. The CWA and regulations implemented thereunder also prohibit discharges of dredged and fill material in wetlands and other waters of the U.S. unless authorized by a permit issued by the U.S. Army Corps of Engineers.

 The Safe Drinking Water Act, as amended ("SDWA"), and the Underground Injection Control ("UIC") program promulgated thereunder regulate the drilling and operation of subsurface injection wells. The program requires that a permit be obtained before drilling a disposal well. The EPA directly administers the UIC program in some states, and in others the responsibility for certain aspects of the program has been delegated to the state. Violation of these regulations and/or contamination of groundwater by mining related activities may result in fines, penalties, and/or remediation costs, among other sanctions and liabilities under the SDWA and state laws.

 The Endangered Species Act ("ESA") regulates activities that could have an adverse effect on threatened and endangered species, including the habitat and ecosystems upon which they depend. The ESA protects threatened and endangered species primarily by prohibiting the unauthorized "taking" of listed species, which includes harassing or harming members of such species or significantly modifying their habitat. The ESA also requires consultation with other agencies in certain circumstances. Compliance with ESA requirements can significantly delay, limit, or even prevent the development of projects, including the development of mining claims, and can also result in increased development costs. In addition, the ESA authorized both civil and criminal penalties for ESA violations and authorizes citizen suits against any person alleged to be in violation of the ESA.

 Regulations and pending legislation governing issues involving climate change could result in increased operating costs that could have a material adverse effect on our business.
 A number of governments or governmental bodies have adopted or are contemplating regulatory changes in response to the potential impact of climate change. In the U.S., on December 15, 2009, the EPA published its findings that emissions

 of carbon dioxide, methane and other GHGs present an endangerment to public health and the environment because emissions of such gases are, according to the EPA, contributing to the warming of the earth's atmosphere and other climate changes. Based on these findings, the EPA has developed and implemented regulations that restrict GHG emissions under existing provisions of the CAA, including one rule that limits GHG emissions from motor vehicles beginning with the 2012 model year. The EPA has asserted that these final motor vehicle GHG emission standards trigger the CAA construction and operating permit requirements for stationary sources, commencing when the motor vehicle standards took effect on January 2, 2011. On June 3, 2010, the EPA published its final rule to address the permitting of GHG emissions from stationary sources under the Prevention of Significant Deterioration ("PSD") and Title V permitting programs. This rule "tailored" these permitting programs to apply to certain stationary sources of GHG emissions in a multi-step process, with the largest sources first subject to permitting. However, based on a decision of the U.S. Supreme Court, only facilities already required to obtain PSD permits for other criteria pollutants must also reduce GHG emissions that exceed certain thresholds consistent with guidance for determining "best available control technology" standards for GHG, which guidance was published by the EPA in November 2010.
 In addition, both houses of Congress have considered legislation to reduce GHG emissions and many states have already taken legal measures to reduce GHG emissions, primarily through the development of GHG inventories, GHG emission fees, GHG permitting and/or regional GHG "cap and trade" programs. Most of these "cap and trade" programs work by requiring major sources of emissions to acquire and surrender emission allowances, with the number of allowances available for purchase reduced each year until the overall GHG emission-reduction goal is achieved. The current U.S. presidential administration has made climate change legislation and regulation a priority, which increases the likelihood of increased regulation of GHG emissions. Although the U.S. had withdrawn from the Paris Agreement, the U.S. formally rejoined the Paris Agreement in February 2021, and, in April 2021, the Biden Administration set an economy-wide target of reducing its net greenhouse gas emissions by 50-52% below 2005 levels in 2030. With the U.S. recommitting to the Paris Agreement, additional executive orders may be issued, or federal legislation or regulatory initiatives may be adopted to achieve the Paris Agreement's goals.
 Legislation and increased regulation regarding climate change could impose significant costs on us and/or our suppliers, including costs related to increased energy requirements, capital equipment, environmental monitoring, and reporting and/or other costs to comply with such regulations. Any adopted future climate change regulations could also negatively impact our ability to compete with companies situated in areas not subject to such regulations. Alternatively, climate change legislation could potentially benefit our business by driving demand for products utilizing rare earth containing products. We cannot predict how legislation and regulation will affect our financial condition, operating performance, or ability to compete. Even without such regulation, increased awareness, or any adverse publicity in the global marketplace about the rare earth industry's potential impacts on the environment could harm our reputation and business. The potential physical impacts of climate change on our operations are highly uncertain and would be particular to the geographic circumstances in the areas in which we operate. These may include changes in precipitation, storm patterns and intensities, water shortages and changing temperatures. These factors may have an adverse impact on the cost, production, or financial performance of our operations.
 A shortage of equipment and supplies could adversely affect our ability to operate our business.
 We currently do and likely will depend on various supplies and equipment to carry out our activities, including those for the Demonstration Plant, and, if warranted, future exploration, development, mining, and processing operations. A shortage of such supplies, equipment or parts could have a material adverse effect on our ability to carry out our planned activities or increase our operating costs and expenses.
 Mineral exploration and development and mining are potentially hazardous and subject to conditions or events beyond our control, which could have a material adverse effect on our business or plans.
 Mineral exploration, development and mining involve various types of risks and hazards, including, but not limited to the following:

 environmental hazards;

 power outages;

 metallurgical and other processing problems;

 unusual or unexpected geological formations or conditions;

 personal injury, flooding, fire, explosions, cave-ins, earthquakes, landslides, and rock-bursts;

 mineral exploration, transportation, or mining accidents;

 concentrate losses;

 fluctuations in exploration, development, and production costs;

 labor disputes;

 supply interruptions;

 unanticipated variations in grade;

 mechanical equipment failure;

 periodic interruptions due to inclement or hazardous weather conditions; and

 regulatory delays, curtailments, or shutdowns.

 These risks could result in damage to, or destruction of, mineral properties, production equipment, facilities or other properties, personal injury, environmental damage, delays in mining, increased production costs, monetary losses, or possible legal liability. We may not be able to obtain insurance to cover these risks at economically feasible premiums or at all. Insurance against certain environmental risks, including potential liability for pollution or other hazards resulting from the disposal of waste products from production, may be prohibitively expensive or not available. Any losses we incur related to any significant events that are not covered by insurance policies may have a material adverse effect on our business.
 Mineral exploration and development is highly speculative, and certain inherent risks could have a negative effect on our business.
 Our long-term success depends primarily on our ability to develop mineral deposits on existing properties that can be developed into commercially viable mining operations. Resource exploration is a highly speculative business, characterized by a number of significant risks, including, among other things, unprofitable efforts resulting not only from the failure to discover mineral deposits but from finding mineral deposits which, though present, are insufficient in quantity and quality to return a profit from production. Substantial expenditures are required to establish proven and probable mineral reserves through drilling and analysis, to develop metallurgical processes to extract metal, and to develop the mining, processing and/or beneficiation facilities and infrastructure at any site chosen for mining. The marketability of minerals discovered by us may be affected by numerous factors that are beyond our control and cannot be accurately predicted, such as market pricing fluctuations, the proximity and capacity of milling facilities, mineral markets demand, available supply and processing equipment, and other factors such as government regulations, including regulations relating to royalties, allowable production, importing and exporting of minerals, and environmental protection. Any one or a combination of these factors may result in a failure to receive an adequate return on our investment capital. The decision to abandon a project may have a material adverse effect on the market value of our common shares or our ability to complete future financings.
 Title to our Bear Lodge Property may be subject to other claims, or we may lose our interest in our claims, which could affect our property rights and claims.
 There are risks that title to our Bear Lodge Property may be challenged or impugned. Our Bear Lodge Property is located in the state of Wyoming and may be subject to prior unrecorded agreements, transfers or native land claims, and title may be affected by undetected defects. There may be valid challenges to the title of our Bear Lodge Property which, if successful, could impair or result in the cessation of development and/or operations.
 The vast majority of the mineral rights to our Bear Lodge Property consist of "unpatented" mining claims created and maintained in accordance with the U.S. General Mining Act of 1872 ("U.S. General Mining Law"). Unpatented mining claims are unique property interests and are generally considered to be subject to greater title risk than are other real property interests because the validity of unpatented mining claims can be uncertain. This uncertainty arises, in part, out of the complex federal and state laws and regulations an owner of an unpatented mining claim must comply with to locate and maintain a valid claim. Also, unpatented mining claims are always subject to possible challenges by third parties or

 validity contests by the federal government. The validity of an unpatented mining claim, in terms of both its location and its maintenance, is dependent on strict compliance with not only a complex body of U.S. federal and state statutory law, but also administrative and judicial decisions interpreting those statutes and case law. In addition, there may be limitations as to the completeness of public records that determine prior claimants that could impact the validity or ownership of unpatented mining claims. The Company's right to continue activities on the Bear Lodge Property is dependent upon our ability to pay annual claim maintenance fees.
 Our operations are subject to significant uninsured risks that could negatively impact future profitability as we maintain limited insurance against our operations.
 Any exploration of our Bear Lodge Property will entail certain risks including unexpected or unusual operating conditions, such as rockslides, cave-ins, flooding, fire, and earthquakes. It is not always possible to insure against these risks. Should events such as these arise, they could reduce or eliminate our assets and shareholder equity as well as result in increased costs and/or a decline in the value of our assets or common shares. We expect to maintain general liability, director and officer insurance, and some insurance against our assets but not with the expectation of full replacement value. We may decide to update or amend our insurance portfolio in the future if coverage is available at economically viable rates.
 Increased competition could adversely affect our ability to attract necessary capital funding.
 The mining industry is intensely competitive, and we must compete with other individuals and companies, many of which have greater financial resources, operational experience, and technical capabilities than we have. This competition from other mining companies could adversely impact our efforts to hire experienced mining professionals. Competition for resources at all levels can be very intense, particularly affecting the availability of manpower, drill rigs, mining equipment and production equipment. Increased competition could adversely affect our ability to attract necessary capital funding or attract or retain key personnel or outside technical resources.
 Land reclamation requirements for our properties may be burdensome or expensive.
 Although land reclamation requirements vary depending on the location and governing authority, such requirements generally are imposed on mineral exploration companies as well as companies with mining and processing operations to minimize long-term effects of land disturbance.
 Reclamation requirements may include the following, among other things:

 control dispersion of potentially deleterious effluents;

 manage and control mine tailings and other processing wastes;

 reduce open pit mine slope angles;

 treat ground and surface water to drinking water standards; and

 reasonably re-establish pre-disturbance vegetation and land forms.

 To carry out reclamation obligations imposed on us in connection with the potential future development activities at the Demonstration Plant and the Bear Lodge Property, we must allocate financial resources that might otherwise be spent on further exploration and future development programs. We have set up a provision for reclamation obligations as currently anticipated for exploration completed on the Bear Lodge Property, as appropriate, but this provision may not be adequate. If we are required to carry out unanticipated reclamation work, our financial position could be adversely affected.
 Legislation and regulations have been proposed that would significantly affect the mining industry and our business.
 The U.S. Congress from time to time has considered proposed revisions to the U.S. General Mining Law. If Congress again considers and enacts any such revisions, such legislation could change the cost of holding unpatented mining claims or significantly impact our ability to develop mineralized resources on unpatented mining claims. Changes in the U.S. presidential administration or changes in the composition of Congress from time to time may increase the likelihood that Congress considers such revisions at some point. Past bills have proposed, among other things, to (i) impose a federal

 royalty on production from unpatented mining claims, (ii) impose a fee on the amount of material displaced at a mine, (iii) impose time limits on the effectiveness of plans of operation that may not coincide with mine life, (iv) impose more stringent environmental compliance and reclamation requirements on activities on unpatented mining claims, (v) establish a mechanism that would allow states, localities and Native American tribes to petition for the withdrawal of identified tracts of federal land from the operation of the U.S. General Mining Law, (vi) replace the location of mining claims with federal leases for locatable minerals, and (vii) allow for administrative determinations that mining would not be allowed where undue degradation of the federal lands in question could not be prevented. Although we cannot predict what legislated royalties might be, the enactment of a federal royalty or other provisions contained in any such proposed bills could adversely affect the potential for development of our unpatented mining claims, our ability to operate, or our financial performance. The effect of any proposed revision of the U.S. General Mining Law on operations cannot be determined until enactment. However, it is possible that revisions would materially increase the carrying and operating costs of mineral properties located on federal unpatented mining claims.
 Risks Related to Our Common Stock
 We may elect to deregister our common shares under the Exchange Act. Deregistration would result in less disclosure about us and may negatively affect the liquidity and trading prices of our common shares.
 Due to the relatively high cost of being a public company in the U.S., our Board of Directors may elect to voluntarily deregister our common shares under the Exchange Act and suspend our reporting obligations in the U.S., possibly in combination with an effort to list our common shares on a securities exchange. No Board approval of deregistration has taken place, but in the future, the Board may authorize the Company to file with the SEC a Form 15 to voluntarily deregister our common shares under Section 12(g) of the Exchange Act and suspend our reporting obligations under Section 15(d) of the Exchange Act. If the Board approves such deregistration, we would file a Form 15 and our obligations to file periodic reports, such as annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, would be suspended immediately upon the filing of the Form 15 with the SEC, and our proxy statement, Section 16 and other Section 12(g) reporting responsibilities would terminate effective 90 days after the filing of the Form 15. We believe that we are eligible to deregister under the Exchange Act. If we were to file a Form 15, we expect that our common shares, which currently trade on the OTCQB Venture Marketplace, would not continue to be quoted on the OTCQB Venture Marketplace. Following any deregistration, we would not expect to publish periodic financial information or furnish such information to our shareholders except as may be required by applicable laws or stock exchange rules. As a result of the foregoing factors, deregistration may result in less disclosure about us and may negatively affect the liquidity and trading prices of our common shares.
 We do not currently intend to pay cash dividends.
 We have not declared any dividends since our incorporation and do not anticipate that we will do so in the foreseeable future. Our present policy is to retain all available funds for use in our business development and operations. Payment of future cash dividends, if any, will be at the discretion of the Board of Directors and will depend on our financial condition, results of operations, contractual restrictions, capital requirements, business prospects and other factors that the Board of Directors considers relevant. In the absence of dividends, investors will only see a return on their investment if the value of our common shares appreciates.
 Future sales of our securities in the public or private markets could adversely affect the trading price of our common shares or our ability to continue to raise funds in new equity offerings.
 It is possible that we will sell common shares, or securities exercisable or convertible into common shares, in order to finance our planned development activities. Future sales of substantial amounts of our securities in the public or private markets would dilute our existing shareholders and potentially adversely affect the trading prices of our common shares or could impair our ability to raise capital through future offerings of securities. Alternatively, we may rely on debt financing and assume debt obligations that require us to make substantial interest and principal payments that could adversely affect our business or future growth potential.

 Price volatility of our publicly traded securities could adversely affect investors' portfolios.
 In recent years and months, the securities markets in the U.S. and Canada have experienced high levels of price and volume volatility, and the market prices of securities of many companies have experienced wide fluctuations that have not necessarily been related to the operating performance, underlying asset values or prospects of such companies. There can be no assurance that continual fluctuations in the market price of our common shares will not occur. It may be anticipated that any quoted market for the common shares will be subject to market trends and conditions generally, notwithstanding any potential success we have in creating revenues, cash flows or earnings. The price of our common shares has been subject to price and volume volatility in the past and will likely continue to be subject to such volatility in the future.
 Because our common shares are not listed on a national securities exchange, a broker-dealer may find it more difficult to trade our common shares, and an investor may find it more difficult to acquire or dispose of our common shares in the secondary market.
 We are subject to the so-called "penny stock" rules. The SEC has adopted regulations that define a "penny stock" to be any equity security that has a market price per share of less than $5.00, subject to certain exceptions, such as any securities listed on a national securities exchange. For any transaction involving a "penny stock," unless exempt, the rules impose additional sales practice requirements on broker-dealers, subject to certain exceptions. A broker-dealer may find it more difficult to trade, and an investor may find it more difficult to acquire or dispose of, our common shares on the OTCQB Venture Marketplace. These factors could significantly negatively affect the market price of our common shares and our ability to raise capital.
 General Risk Factors
 Market factors outside of our control could have significant adverse impacts on our business, operations and/or prospects.
 Operating in the volatile and cyclical natural resource industry subjects us to numerous market factors outside of our control that could have significant and sometimes adverse impacts on our business. Such factors could include significant price declines for key rare earth materials, inflationary impacts on capital and operating costs, public opposition, poor financial and operating performance of other companies in the same industry sector, environmental incidents from resource projects, major technological advances that reduce demand for key rare earth products, unforeseen regulation, military conflict, such as the Russia/Ukraine war, the conflicts in the Middle East, terrorism, banking institution stability, or other geopolitical events that broadly impact the global or domestic economy or natural resource industry. To the extent that such events affect attitudes toward investments in the natural resource sector generally or the rare earths industry specifically, or impact the overall economic climate, could affect our ability to raise the additional capital needed to continue to advance our Projects and business plan.
 Our directors, officers and consultants may be engaged in other businesses. Potential conflicts of interest or other obligations of directors, officers and consultants could interfere with corporate operations.
 Some of our directors, officers and consultants may be engaged in additional businesses, or situations may arise where our directors, officers and consultants could be in direct competition with us. Conflicts, if any, will be dealt with in accordance with the relevant provisions of applicable policies, regulations, and legislation. Some of our directors and officers are or may become directors or officers of other entities engaged in other business ventures. As a result of their other business endeavors, our directors, officers, and consultants may not be able to devote sufficient time to our business affairs, which may negatively affect our ability to conduct ongoing operations or to generate revenues.
 We are subject to the risk of litigation, the causes and costs of which are not always known.
 We are subject to litigation arising in the normal course of business and may be involved in disputes that may result in litigation. Although we are not aware of any material pending or threatened litigation or of any legal proceedings known to be contemplated which are, or would be, likely to have a material adverse effect upon us or our operations, taken as a whole, the causes of potential future litigation cannot be known and may arise from, among other things, business activities,

 environmental and health and safety concerns, share price volatility or failure to comply with disclosure obligations. The results of litigation cannot be predicted with certainty but could include costly damage awards or settlements, fines, and the loss of licenses, concessions, or rights, among other things. If we are unable to resolve a dispute favorably, either by judicial determination or settlement, it may have a material adverse effect on our financial condition, cash flows or results of operations.
 We depend upon information technology systems, which are subject to cyber-attacks, disruption, damage, or failure and have risks associated with implementation and integration.
 We depend upon information technology systems in the conduct of our operations. Our information technology systems are subject to disruption, damage, or failure from a variety of sources, including, without limitation, computer viruses, security breaches, cyber-attacks, natural disasters, and defects in design. Cybersecurity incidents, in particular, are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic security breaches that could lead to disruptions in systems, financial losses, unauthorized releases of confidential or otherwise protected information or the corruption of data. Furthermore, as artificial intelligence capabilities improve and are increasingly adopted, we may see cyber-attacks created through artificial intelligence. Various measures have been implemented to manage our risks related to information technology systems and network disruptions. However, given the unpredictability of the timing, nature and scope of information technology disruptions, we could potentially be subject to downtimes, operational delays, the compromising of confidential or otherwise protected information, destruction or corruption of data, security breaches, other manipulation or improper use of our systems and networks or financial losses from remedial actions, any of which could have a material adverse effect on our cash flows, competitive position, financial condition or results of operations. See "Item 1C. Cybersecurity" of this Annual Report for more information about the systems and processes we use to manage these risks.

 ITEM 1B. UNRESOLVED STAFF COMMENTS
 Not applicable.

 ITEM 1C. CYBERSECURITY

 We face cybersecurity risks due to the breadth of networks and systems we must defend against cybersecurity attacks and threat actors seeking to inflict harm on us; and the substantial level of harm that could occur to us were we to suffer impacts of a material cybersecurity incident. We are committed to maintaining robust governance and oversight of these risks and to implementing mechanisms, controls, technologies, and processes designed to help us assess, identify, and manage these risks. In the year ended December 31, 2023, we did not experience a material "cybersecurity incident" as such term is defined in Item 106(a) of Regulation S-K. However, there can be no guarantee that we will not experience such an incident in the future. Such incidents, whether or not successful, could result in us incurring significant costs related to, for example, implementing additional threat protection measures, defending against litigation, responding to regulatory inquiries or actions, paying damages, or taking other remedial steps with respect to third parties, as well as incurring significant reputational harm. In addition, these threats are constantly evolving, thereby increasing the difficulty of successfully defending against them or implementing adequate preventative measures. We seek to detect and investigate unauthorized attempts and attacks against our network, and to prevent their occurrence and recurrence where practicable through changes or updates to our internal processes and tools; however, we remain potentially vulnerable to known or unknown threats. In some instances, we and our suppliers may be unaware of a threat or incident or its magnitude and effects. Further, there is increasing regulation regarding responses to cybersecurity incidents, including reporting to regulators, which could subject us to additional liability and reputational harm. See "Item 1A. Risk Factors" of this Annual Report for more information on our cybersecurity risks and product vulnerability risks.
 We aim to incorporate industry best practices throughout our cybersecurity program. Our cybersecurity strategy focuses on implementing effective and efficient controls, technologies, and other processes to assess, identify, and manage material cybersecurity risks. Our cybersecurity program is designed to be aligned with applicable industry standards and is maintained by a third-party technology firm. The third-party firm has processes in place to assess, identify, manage, and address material cybersecurity threats and incidents. These include, among other things, annual and ongoing security

 awareness training for employees; mechanisms to detect and monitor unusual network activity; and containment and incident response tools.
 Our Board of Directors has ultimate oversight of cybersecurity risk, which it manages as part of our enterprise risk management program. That program is utilized in making decisions with respect to Company priorities, resource allocations, and oversight structures. The Board of Directors is assisted by the Audit Committee, which regularly reviews our cybersecurity program with management and reports to the Board of Directors.
 Our cybersecurity program is run by a third-party firm, which reports to our Chief Financial Officer ("CFO"). The third-party firm is informed about and monitors prevention, detection, mitigation, and remediation efforts through regular communication and reporting from professionals within its team and through the use of technological tools and software. Our CFO regularly reports directly to the Audit Committee or the Board of Directors on our cybersecurity program and efforts to prevent, detect, mitigate, and remediate issues. Cybersecurity reviews by the Audit Committee or the Board of Directors generally occur at least annually, or more frequently as determined to be necessary or advisable.

 ITEM 2. PROPERTIES
 Information concerning our mining property in this Annual Report has been prepared in accordance with the requirements of CFR Title 17, Subpart 229, Item 1300-1305 of Regulation S-K, which requires us to disclose our mineral resources and reserves as of the end of our most recently completed fiscal year for our material mining property.
 As used in this Annual Report, the terms "mineral resource," "measured mineral resource," "indicated mineral resource," "inferred mineral resource," "mineral reserve," "proven mineral reserve" and "probable mineral reserve" are defined and used in accordance with Subpart 229, Item 1300 of Regulation S-K. Under Subpart 1300 of Regulation S-K and NI 43-101, mineral resources may not be classified as "mineral reserves" unless the determination has been made by a qualified person that the indicated and measured mineral resources can be the basis of an economically viable project. We currently have no mineral reserves, and you are specifically cautioned not to assume that any part or all of the mineral resources will ever be converted into mineral reserves, as defined by the SEC. See "Item 1A. Risk Factors" of this Annual Report.
 You are cautioned that, except for that portion of mineral resources classified as mineral reserves, mineral resources do not have demonstrated economic value. Inferred mineral resources are estimates based on limited geological evidence and sampling and have too high of a degree of uncertainty as to their existence to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. It should not be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. A significant amount of exploration must be completed in order to determine whether an inferred mineral resource may be upgraded to a higher category. Therefore, you are cautioned not to assume that all or any part of an inferred mineral resource exists, that it can be considered when assessing the economic viability of a mining project, or that it will ever be upgraded to a higher category. Likewise, you are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted to mineral reserves. See "Item 1A. Risk Factors" of this Annual Report.
 The information that follows relating to the Bear Lodge REE Project is derived from, and in some instances is an extract from, the TRS relating to the Bear Lodge REE Project prepared in compliance with CFR Title 17, Subpart 229, Item 601(b)(96) of Regulation S-K. Portions of the following information are based on assumptions, qualifications and procedures that are not fully described herein. Reference should be made to the full text of the TRS, incorporated herein by reference and made a part of this Annual Report. We are in the process of completing an NI 43-101 compliant technical report for the Bear Lodge REE Project, and we do not expect that there will be any material differences between the NI 43-101 compliant technical report and the information set forth below and contained in the TRS.

 Individual Property Disclosure
 Bear Lodge Property
 The Bear Lodge Property, which is located in Central Crook County, Wyoming, contains two projects, the Bear Lodge REE Project and the Sundance Gold Project. The Bear Lodge REE Project consists of the Bull Hill and Whitetail Ridge deposits and the exploration targets of East Taylor ("Taylor") and Carbon Hill ("Carbon") deposits, all of which are located near Sundance, Wyoming. The Bear Lodge REE Project also includes the proposed processing and separation plant as well as the Demonstration Plant (under construction) in Upton, Wyoming. See the property location map below. Additional details on each of these areas are set forth below under the heading "Bear Lodge REE Project." We hold our interest in the Bear Lodge Property through our indirect wholly-owned subsidiary, Rare Element Resources, Inc., a Wyoming corporation.
 Bear Lodge Property – Location Map

 We control 100% of the mineral rights at the Bear Lodge Property, consisting of unpatented mining claims and a right of repurchase on adjacent private land (Section 16). We hold 499 unpatented mining claims located on land administered by the USFS. The Bear Lodge Property is located within parts of Sections 5, 6, 7, 8, 9, 14, 15, 16, 17, 18, 19, 21, 22, 23, 26, 27, 28, 29, 30, 31, 32, 33, 34 and 35 in Township 52 North and Range 63 West, Sixth Principal Meridian, Crook County, Wyoming. All of the public property mining claims are unpatented, such that the paramount title to the land is held by the U.S. All of the mineral resources identified in the TRS are located on mining claims that we hold.

 On October 25, 2021, the Company and Whitelaw Creek LLC, a Wyoming limited liability company ("Whitelaw Creek"), entered into an amendment (the "Amendment") to the asset purchase agreement dated October 20, 2016 between the Company and Whitelaw Creek (the "APA"). The Amendment modified certain provisions of the APA related to the terms and conditions of the Company's option to repurchase (the "Repurchase Option") approximately 640 acres of non-core real property located in Crook County, Wyoming, that is under consideration for a stockpile facility for the Bear Lodge REE Project. Pursuant to and subject to the terms of the Amendment, among other things, the term of the Repurchase Option (which was to expire on October 26, 2021) was extended for up to three additional years, subject to annual option extension payments from the Company to Whitelaw Creek of $25 in cash per year (each, a "Repurchase Option Extension Payment"); and the exercise price of the Repurchase Option was increased from $1,000 to a price to be determined by a mutually agreed upon real estate appraiser (the "Repurchase Price"), provided that (i) the Repurchase Price must not be less than $1,200 or greater than $1,850 and (ii) any Repurchase Option Extension Payments paid by the Company to Whitelaw Creek must be credited toward the Company's payment of the Repurchase Price if the Repurchase Option is later exercised. In October 2023, the Company made the $25 Repurchase Option Extension Payment to Whitelaw Creek to extend the term of the Repurchase Option through October 26, 2024.
 Our 100% interest in the 499 unpatented mining claims was, in part, acquired from Phelps Dodge Exploration Company (now a subsidiary of Freeport-McMoRan Copper and Gold Inc. ("Freeport") by way of a Mineral Lease and Option for Deed in 2000, and 404 claims were transferred from Newmont Mining Corporation ("Newmont") to us in May 2010.
 Some of our mining claims and a portion of a defined area of influence surrounding the claims were previously subject to a production royalty of 2% of net smelter returns ("NSR") royalty payable to Freeport, but the Company purchased the NSR royalty in March 2009. We hold an unencumbered REE project, including all 499 unpatented mining claims, free of third-party royalties for REE production.
 In order to maintain all claims in good standing, the Company is responsible for the payment of annual federal claim maintenance fees (currently $0.165/claim) and the recording of the annual claim maintenance and intent to hold notice with Crook County, Wyoming. All 499 unpatented claims included in the project are located on both federal and private lands and are subject to annual maintenance fees payable to the United States Bureau of Land Management. Mineral rights on the mining claims and the approximately 640-acre private parcel under the Repurchase Option provide the Company mineral and surface rights to explore, develop, and mine the Bear Lodge Property, subject to the prior procurement of required operating permits and approvals and compliance with applicable federal, state, and local laws, regulations, and ordinances.
 Infrastructure
 Exploration has been conducted on the Bear Lodge Property since 1949. In addition to Freeport, several mining companies have conducted exploration and drilling programs at or near the Bear Lodge Property since the discovery of mineralization. No mining operations were conducted at the Bear Lodge Property by any of the prior owners.
 Motels, restaurants, gas stations, and other services are available at Sundance, Upton, and other nearby towns, and a greater variety of accommodations are available to the east in Spearfish, South Dakota. All necessary infrastructure, such as housing, food, fuel, etc. would be available in these towns or further to the west in Gillette and southeast in Newcastle. Water rights at the mine site are available through permitting by the Wyoming State Engineer's Office; these water rights have not been secured at the time of reporting. Near the mine site, a power line, which requires upgrading, runs to within a mile of the Bear Lodge Property.
 Supplies can be trucked to the Bear Lodge Property 60 miles (100 kilometers) from Gillette, which is located on both U.S. Interstate Highway 90 and rail lines. A Burlington Northern Santa Fe rail transport line is also located at Moorcroft, 34 miles (54 kilometers) west of Sundance, and at Upton, 40 miles (64 kilometers) south. The Powder River Basin contains multiple power plants, and Gillette, the largest city in the basin, would be a major logistics center for any development at the Bear Lodge Property. The current size of the mine property is sufficiently large to support a mining operation, with no foreseeable obstacles to expansion, subject to a favorable outcome regarding permitting.

 Condition of the Property
 We are not aware of any outstanding environmental liabilities associated with the Bear Lodge Property, except for the required reclamation work associated with our exploration and drilling activities. Previous exploration activities were approved by both the USFS and the Wyoming Department of Environmental Quality. We have an approved reclamation plan and have posted surety bonds to cover the required reclamation.
 Additional local, state, and federal licenses and permits will be required for exploration, mining, processing and/or beneficiation operations, if we decide to proceed with further exploration or mine development and operations.
 The Bear Lodge Property is an exploration stage property with no proven or probable reserves. There has been no historical production from the property.
 The Bear Lodge REE Project
 The Bear Lodge REE Project is located in Central Crook County, northeastern Wyoming, in the northwestern portion of the Black Hills uplift. The property is situated in the central Bear Lodge Mountains, a relatively small northwesterly trending range. The project is flanked to the west by the Powder River Basin, famous for its extensive coal mining, and is adjoined by the Great Plains to the southeast. See the property location map below.
 The Bear Lodge REE Project lies about seven air miles (11 kilometers) or 12 road miles (19 kilometers) northwest of the town of Sundance (Wyoming), approximately 22 air miles (35 kilometers) west of the South Dakota state line, 55 air miles (89 kilometers) east of Gillette (Wyoming), and 230 miles (370 kilometers) north of Cheyenne, the Wyoming state capitol. Gillette is the headquarters for much of the Wyoming coal mining industry.

 General Property Location Map

 Geological Setting
 The Bear Lodge Mountains of northeast Wyoming are part of the Black Hills Uplift, which has a northwesterly orientation and extends from the western South Dakota – Nebraska border through northeastern Wyoming into southeastern Montana. The exposed basement consists of Precambrian schist, gneiss, and granite overlain by Paleozoic and Mesozoic clastic and carbonate sedimentary rocks eroded from higher elevations. Eocene (Tertiary) alkaline intrusive and extrusive bodies in the northern Black Hills form an N70 -80 W trending belt that extends from Bear Butte in South Dakota through the Bear Lodge Mountains, Devil's Tower, and Missouri Buttes in northeastern Wyoming. These alkaline igneous rocks are represented by dikes, sills, stocks, laccoliths, diatremes, and ring complexes are associated with REE-enriched carbonatite dikes in the Bear Lodge alkaline-igneous complex.
 The Bear Lodge alkaline-igneous complex is a northwest-trending alkaline intrusive dome with dimensions of approximately 10 kilometers NW-SE by six kilometers NE-SW. The complex consists predominantly of multiple intrusions of phonolite, trachyte, and other alkaline igneous rocks, and a variety of associated breccias and diatremes.
 Exploration and Drilling
 The Bear Lodge Mountains were initially prospected for gold during the late nineteenth and early twentieth century. Rare earth mineralization was first discovered in approximately 1949. Various companies conducted sporadic exploration of the area from the 1970s through the 1990s, both for rare earths and for gold. Commencing in 2004, we initiated REE exploration activities and from 2004 through 2013, a total of more than 160,000 feet of drilling was completed in over 200 core holes. These exploration activities included geochemical, geophysical, geological, and mineralogical modeling of the district and individual deposits.
 The 2013 drilling program involved infill drilling at the Whitetail Ridge deposit including 14 core holes for a total of 3,556.5 meters (11,698 feet). The second phase consisted of 21 core holes totaling 3,247 meters (10,651 feet) and six reverse circulation ("RC") twin holes totaling 832 meters (2,730 feet). The RC twin holes were drilled using a center return hammer with the objective of minimizing hole erosion and obtaining assay data directly correlative to that from the adjacent core holes.
 The 2014 program consisted of excavating a test trench along the southwestern flank of Bull Hill in August. The main mineralized zone was exposed and exploited to collect geological information, including dike dimension and structural continuity, grade variation, ore and gangue mineralogy, pit slope stability engineering and confirmation of parameters utilized in ore resource calculations. The program netted 700 tonnes of sample materials, the bulk of which is stored for current and future metallurgical work.
 No exploration drilling was conducted from 2013 through the end of 2023 and no drilling or exploration activities are currently planned for 2024.
 Mineralization
 The Bear Lodge REE Project comprises two main areas represented by the Bull Hill and Whitetail Ridge deposits, as well as the exploration targets of the Carbon Hill and East Taylor deposits (see map below). All the deposits have carbonatite-related dikes and veins that range in size from hairline fracture veinlets to dikes that may exceed 80 feet (24.4 meters) in width. Lower-grade stockworks of veinlets commonly surround the higher-grade REE-bearing dikes and veins. Oxidized mineralization (FMR and OxCa) extends to depths of 500 to 600 feet (152 to 183 meters). Oxide zone REE mineralization is dominated by REE minerals of the bastn site group, with variable and typically subordinate quantities of monazite and cerianite. Oxide-carbonate mineralization contains a variable mix of bastn site group minerals and ancylite, with varied and subordinate amounts of monazite and cerianite.

 Bull Hill District Grade Shells
 REE mineralization is widespread on the property. However, the area proximal to the Bull Hill and Whitetail diatreme bodies is believed to be the most prospective for significant REE mineralization.
 Bull Hill and Whitetail Ridge Deposits
 The Bull Hill deposit mineralized bodies occur as steeply dipping, FMR-carbonatite dike swarms, and associated stockwork. Geological interpretation of results from the 2010–2014 drill and trench programs indicates that the Bull Hill deposit area is dominated by northwest-striking mineralized bodies in the southern two-thirds of the resource area, while the northern part of the resource area exhibits a transitional change in strike from a north-westerly to a north-easterly direction. The dike swarm primarily intrudes heterolithic intrusive breccia of the Bull Hill diatreme and adjacent trachytic and phonolitic intrusive rocks. Carbonatite dikes at depth are interpreted to transition toward the surface into OxCa and FMR bodies. The mineralized structures range in size from veinlets to large dikes more than 30 meters in width. The Bull Hill deposit consists of one dominant dike set and several subsidiary dike sets in a swarm that has dimensions of more than 457 meters along strike and less than 100 meters in width. The dikes appear to pinch and swell in both strike and dip directions, and they can be traced in drill holes more than 305 meters down dip.
 The Whitetail Ridge deposit occurs about 700 meters northwest of the Bull Hill deposit. The REE mineralization consists of northwest- and north-striking FMR dikes, and an FMR stockwork zone that is also elongated northeasterly, with dimensions of roughly 380 meters by 290 meters. The enveloping gravity and radiometric geophysical anomalies and coincident soil geochemical anomalies are larger and may indicate a broader distribution of REE mineralization beneath the extensive soil and colluvial cover. Drilling conducted from 2011 through 2013 indicates that much of the mineralization is confined within the volume of the Whitetail Ridge diatreme.
 Other Exploration Target Areas at the Bear Lodge REE Project
 The discovery of high-grade REE mineralization at the East Taylor and the Carbon target areas expanded the area of known REE mineralization outside of the Bull Hill and Whitetail Ridge deposits. The data indicates that the Bear Lodge REE Project area covers a crudely elliptical area that extends approximately 1,750 meters northwest-southeast by 1,300 meters northeast-southwest. The Carbon exploration target area is located northwest of the Bull Hill deposit, and the East Taylor Target Area is located west of the Bull Hill deposit. Drill assay data from the East Taylor and the Carbon target areas identify these areas as zones of HREE-enrichment relative to the Bull Hill deposit. These two exploration target areas, along with the Whitetail Ridge deposit, are peripheral to the Bull Hill deposit. The discovery of these target areas indicates good potential for additional deposits of high-grade REE in the western half of the Bear Lodge REE Project, and those deposits appear to be particularly enriched in HREE.

 Permitting and Licensing
 The USFS is the lead agency in the NEPA process to prepare an EIS on the Bear Lodge REE Project. This process is essential to securing the permits and approvals necessary to move into production. In early 2012, we submitted the plan of operations for the Bear Lodge REE Project, which the USFS accepted as complete in May 2013. The USFS selected a project manager and prime contractor for the preparation of the draft EIS, published notice in the Federal Register and completed necessary scoping work. The USFS issued a draft EIS on January 15, 2016, outlining plan alternatives and proffering a preferred alternative. The U.S. Army Corps of Engineers and the appropriate state and local government agencies were involved in the EIS process as cooperating agencies. On January 22, 2016, our Board of Directors decided to conserve cash due to the difficult market conditions and suspended all permitting and licensing efforts, including the EIS process. We notified the USFS and cooperating agencies, the NRC, and the state of Wyoming of our decision to suspend permitting and licensing efforts, and the parties acknowledged receipt of the notice. During 2022, the Company undertook environmental sampling to update the baseline environmental data for the Bear Lodge REE Project.
 The Company will be required to obtain permits and licenses to further develop the Bear Lodge REE Project from the USFS, the Wyoming Department of Environmental Quality Land Quality Division (WDEQ-LQD), and the NRC.
 Processing and Decommissioning
 The Company is proceeding with the construction of a rare earth processing and separation Demonstration Plant. The Demonstration Plant is scheduled to be in operation in mid-2024. The Demonstration Plant is expected to advance the Company's proprietary processing and separation technology and generate the operational and economic data necessary for the design of a commercial-scale facility.
 Reclamation of mining-related facilities are planned to occur during mine operations, where applicable, and upon completion of mining and stockpiling of materials. Other facilities would be reclaimed as soon as the stockpiled materials are depleted.
 Mineral Resource Estimate
 In March 2024, the Company announced the completion of a new mineral resource estimate based on maximizing the recovery of La and the key magnet materials of Nd, Pr, Tb, and Dy. The estimate was focused on the oxide zone of the Bull Hill deposit at the Bear Lodge REE Project with long-term upside existing in the Carbon, Whitetail, and Taylor deposits. The resource estimate was based on 252 core holes drilled between 2009 and 2013, including 20,491 assay intervals that totaled 186,712 feet (56,910 meters) of drilling from the Company's drill hole database. The estimate also used the economic data generated from the 2021 pilot plant testing of the Company's proprietary processing and separation technology. The resource estimate focuses on the Ox and OxCa zones of the Bull Hill deposit, which are considered the best plant feed and are expected to have the best recoveries and costs by utilizing the Company's innovative technology.
 The Bull Hill deposit estimates of measured, indicated, and inferred mineral resources, based on a base-case cutoff grade for resource reporting of 2.18% TREO, are summarized in Table 1 below. The effective date of this mineral resource estimate is December 31, 2023 (Table 1).

 Data Verification
 The Company obtained the geological, exploration, and drilling data package from Phelps Dodge and Newmont Corporation, covering most of the work done on the property by various companies and claim owners through 1996. From 2006 until spring 2010, the Company conducted its own REE drilling programs throughout the Bear Lodge Property under a joint venture agreement with the Newmont Mining Corporation ("Newmont"), with the Company maintaining a separate database of REE drilling results. While the Company continued focusing on the exploration for REEs, Newmont's efforts

 continued in gold exploration. Separation of the two exploration drilling programs for REEs and gold, and their respective drilling data continued through the 2009 drill season when the Company assumed control of the program with the termination of Newmont's interest in the property in May 2010.

 Drill hole data prior to 2008 has not been used for resource estimates.

 From 2008 through 2010, the Company compiled analytical data in Excel, Access, and Datamine for use in GIS and 3D mapping software. Between 2010 and 2011, a drill data management system was implemented by EDM Solutions. The drill data management database was built on an MS SQL SERVER platform and was hosted on a secure "Cloud" server with restricted access. Security and backup features were built into the system and were considered industry standard. The data is currently maintained in the Company's archives.

 All on-site drilling programs conducted by the Company were supervised by experienced geology professionals. Company geologists and consultants from Ore Reserves Engineering conducted extensive reviews and verified data from the 2009 – 2013 drilling programs, for use in the TRS resource estimate.

 Drill hole collar surveys for all 2008 through 2013 core holes were surveyed by Bear Lodge Ltd., professional engineers and land surveyors based in Sundance, Wyoming. Down-hole surveys were conducted on all core holes drilled by Company personnel from the 2008 through 2013 drill programs.

 REE assays for the 2009, 2012, and 2013 programs were conducted by Activation Laboratories of Ancaster, Ontario, and assays for the 2010 and 2011 drill programs were done by ALS Laboratories. Both laboratories are independent, ISO 9001 accredited and operate to standards consistent with ISO 17025 methods.

 Dr. Jeffrey Jaacks of Geochemical Applications International Inc. conducted a review of the results for the quality assurance and quality control (QA/QC) program used in rare earth element assaying for the Bear Lodge exploration drill programs (2009-2013). Dr. Jaacks, in his review, concluded that the 2009-2013 drill program analysis/assays to be of an acceptable quality and appropriate for resource estimation.

 Rare Earth Processing and Separation Demonstration Plant Project
 A consortium of companies, of which the Company is a member, and which is led by General Atomics, has secured with the DoE a $21,900 Assistance Agreement for the engineering, construction, operation and decommissioning of a rare earth separation and processing Demonstration Plant to be located in Upton, Wyoming at a leased industrial site near infrastructure (the "Demonstration Plant"). The consortium created by General Atomics, an affiliate of Synchron, includes certain of General Atomics' affiliates, the Company, and LNV, an Ardurra Group, Inc. company, as engineering and construction subcontractor. The Company, as a subrecipient of the award, along with the other consortium members, commenced work on the planning and design of the demonstration project in November 2021, and the Company's contractual arrangement with General Atomics was finalized in December 2021. The DoE funding represents approximately one-half of the total originally estimated costs for the project.
 Pursuant to the Cost Share Funding Assumption Agreement, dated as of November 30, 2021, between the Company and General Atomics, the Company agreed to assume and pay for the approximately one-half non-federal costs incurred by General Atomics and the consortium for the design, construction, operation, and decommissioning of the Demonstration Plant. The original estimate for the non-federal cost-share funding for the Demonstration Plant was secured by the Company through the rights offering that closed in December 2021 and is more fully described in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" of this report as is the rights offering that closed in March 2024 and raised gross proceeds of approximately $35,800 to fund further Demonstration Plant activities and other Company initiatives.
 The purpose of the Demonstration Plant is to process and separate certain rare earth elements from previously stockpiled high-grade sample materials from the Bear Lodge REE P roject, utilizing the Company's proprietary extraction and separation processes. The Demonstration Plant has been designed as a demonstration-scale facility that will produce high-

 purity NdPr, as well as other rare earth oxides. Successful operation will serve as a precursor to a future full-scale production facility.
 Demonstration Plant Permitting and Licensing
 On July 31, 2023, the NRC issued the Company a Source Material License. This license is necessary to allow the processing of previously stockpiled material from the Bear Lodge REE Project at the Company's Demonstration Plant. In November 2023, the DoE's Office of Energy Efficiency and Renewable Energy finalized its NEPA review of the Company's Demonstration Plant issuing a FONSI, completing the federal permitting activity required for construction of the Demonstration Plant. Finally on December 21, 2023, the DoE's Office of Energy Efficiency and Renewable Energy issued a Project Continuation Notice following its approval of the budget for construction of the Company's Demonstration Plant. This approval, along with the completion of the DoE's NEPA review, allowed for the commencement of the construction of the Demonstration Plant.
 The Demonstration Plant will encompass the physical processing of the sample materials followed by chemical processing to extract selected elements. All chemicals will be managed in accordance with federal, state, and local environmental and safety regulations. The Company has obtained a source materials possession license from the NRC as well as an air quality permit from the WDEQ. A road use permit was secured from the USFS to improve the access road to the sample storage location. All licenses and permits required for the construction of the Demonstration Plant have now been secured.
 As part of the project licensing with the NRC, the Company has secured and maintains, on behalf of the Demonstration Plant project, a reclamation bond in the amount of $917 and has posted cash collateral of $183 as security for the bond. The ultimate clean-up and any associated decommissioning costs of the Demonstration Plant are the responsibility of the Company and payment of these costs will be handled through the Cost Share Funding Assumption Agreement.
 Demonstration Plant Project Schedule
 To achieve the Demonstration Plant project objectives, the schedule is divided into three distinct performance periods, which commenced on October 1, 2021. During the performance periods, there are three DoE go/no go decision points.

 Performance Period 1: Design, Permitting and Licensing Commencement – 15 months

 Performance Period 2: Procurement and Construction – approximately 15–17 months

 Performance Period 3: Operations – approximately 12 to 15 months

 The objective of Performance Period 1, which was achieved in December 2022, was the completion of the design of the facility and the establishment of requirements and standards to support the subsequent procurement of process equipment, as well as commencement of permitting and licensing. Licensing and permitting was extended into Performance Period 2 and achieved in early 2024. The objective of Performance Period 2, now underway, is the final procurement of the process equipment and the construction of the Demonstration Plant. The objective of Performance Period 3 is the actual operation of the Demonstration Plant itself in accordance with all local, state, and federal permits, licenses, and regulations.
 The first DoE go/no-go decision point occurred upon final design and was achieved in December 2022. The second go/no go decision point followed the completion of the NRC licensing and DoE NEPA review, and occurred in December 2023, and the third go/no go decision point is at the completion of construction of the plant and achieving readiness for operations and is expected in mid-2024.
 End-of-Project Goals
 The goal of the project is to build and operate a permitted and licensed Demonstration Plant that:

 demonstrates the separation of NdPr at commercially required purity levels;

 produces commercial-purity NdPr as well as mixed light/medium REE concentrate, subject to further refining;

 provides a path for the separation of other rare earths, including Sm, Dy and other essential heavy elements;

 provides a basis for economic scale-up to future commercial capacity;

 provides a basis for the demonstration of improved separation economics with expected fewer process steps and a smaller closed-cycle plant as compared with traditional processing methods; and

 demonstrates a process which may be capable of processing feed from other sources, either from the U.S. or other allied countries.

 Sundance Gold Project
 The Sundance Gold Project is the second project located on our Bear Lodge Property. The Sundance Gold Project consists of 288 unpatented lode mining claims adjacent to the Bear Lodge REE Project in Crook County, Wyoming. In 2011, we published an NI 43-101 compliant technical report that now contains dated estimates of inferred mineral resources on the Sundance Gold Project. As a result of the Company's current focus on the Bear Lodge REE Project, no drilling or exploration on the Sundance Gold Project has been conducted since the end of 2011 and none is currently planned. We have not done sufficient work to classify the historical estimate as a current estimate of mineral resources, mineral reserves, or exploration results, and we are not treating the estimate as a current estimate of mineral resources, mineral reserves, or exploration results.

 ITEM 3. LEGAL PROCEEDINGS
 We are not aware of any material pending or threatened litigation or of any proceedings known to be contemplated by governmental authorities which are, or would be, likely to have a material adverse effect upon the Company or our operations, taken as a whole.

 As used herein, the term "U.S. Holder" means a beneficial owner of our securities that is (a) an individual citizen or resident of the U.S. for U.S. federal income tax purposes; (b) a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the U.S. or any state thereof or the District of Columbia; (c) an estate the income of which is subject to U.S. federal income taxation regardless of its source; or (d) a trust, if (i) a court within the U.S. can exercise primary supervision over the administration of the trust and one or more U.S. persons are authorized to control all substantial decisions of the trust or (ii) a valid election is in effect under applicable Treasury Regulations to treat such trust as a U.S. person.
 Passive Foreign Investment Company Rules
 We will be classified as a passive foreign investment company (a "PFIC") in any taxable year in which, after taking into account the income and assets of certain subsidiaries, either (i) at least 75% of our gross income is passive income, or (ii) at least 50% of the average value of our assets is attributable to assets that produce or are held for the production of passive income. Whether we will be classified as a PFIC in any taxable year is a factual determination and will depend upon our assets, the market value of our common shares, and our activities in each year and is therefore subject to change.
 We believe that we were a PFIC for the year ended December 31, 2023. We expect that we will be a PFIC for the year ending December 31, 2024, and that we may also be a PFIC for subsequent years. The tests for determining PFIC status are dependent upon a number of factors, some of which are beyond our control and can be subject to uncertainties. Accordingly, we cannot provide certainty that we were or were not a PFIC for the year ended December 31, 2023, or that we will or will not be a PFIC for the year ending December 31, 2024, or for any future year. We will use commercially reasonable efforts to provide information as to our status as a PFIC and the PFIC status of any subsidiary in which the Company owns more than 50% of such subsidiary's total aggregate voting power to U.S. Holders who make a written request for such information.
 If we are classified as a PFIC for any taxable year, the so-called "excess distribution" regime will apply to any U.S. Holder of our common shares that does not make a QEF election or mark-to-market election, as described below. Under the excess distribution regime, (i) any gain the U.S. Holder realizes on the sale or other disposition of our common shares (possibly including a gift, exchange in a corporate reorganization, or grant as security for a loan) and any "excess distribution" that we make to such U.S. Holder (generally, any distributions to such holder in respect of our common shares during a single taxable year that are greater than 125% of the average annual distributions received by such U.S. Holder in the three preceding years or, if shorter, such holder's holding period for such common shares), will be treated as ordinary income that was earned ratably over each day in such U.S. Holder's holding period for such common shares; (ii) the portion of any such gains or distributions allocated to the current year or prior years before the first day of the first taxable year beginning after December 31, 1986, in which we became a PFIC would be includible by the U.S. Holder as ordinary income in the current year; (iii) the portion of such gain or distribution that is allocable to prior taxable years during which we were a PFIC will be subject to tax at the highest rate applicable to ordinary income for the relevant taxable years, regardless of the tax rate otherwise applicable to such U.S. Holder and without reduction for deductions or loss carryforwards; and (iv) the interest charge generally applicable to underpayments of tax will be imposed with respect of the tax attributable to each such year. The interest charge discussed above generally will be non-deductible interest expense for individual U.S. Holders.

 Certain elections may be available with respect to our common shares (the so-called "QEF," "mark-to-market," and "deemed sale" elections) if we are a PFIC, but these elections may accelerate the recognition of taxable income and may result in the recognition of ordinary income. If the Company is a PFIC for any tax year during which a U.S. Holder holds our common shares, and no such elections have been made, the Company will continue to be treated as a PFIC with respect to such U.S. Holder, regardless of whether the Company ceases to be a PFIC in one or more subsequent years.
 If a U.S. Holder makes a timely election to treat the Company as a "qualifying electing fund" or "QEF" (a "QEF election") with respect to such U.S. Holder's interest therein, the above-described rules regarding the excess distribution regime generally will not apply. Instead, the electing U.S. Holder would include annually in its gross income its pro rata share of our ordinary earnings and any net capital gain for each taxable year regardless of whether such income or gain was actually distributed. Special rules apply to U.S. Holders who own their interests in a PFIC through intermediate entities or persons.
 A U.S. Holder may make a QEF election only if the U.S. Holder receives certain information (known as a "PFIC annual information statement") from us annually. We will use commercially reasonable efforts to make available to U.S. Holders, upon written request, an accurate PFIC annual information statement for each year in which the Company is a PFIC. A QEF election with respect to our common shares is generally timely filed only if it is made on a timely filed federal income tax return for the first year in the U.S. Holder's holding period for our common shares in which we were a PFIC. A U.S. Holder for whom a QEF election would otherwise be untimely may be able to make a special "deemed sale" election pursuant to which the U.S. Holder recognizes any gain inherent in the U.S. Holder's common shares and restarts the U.S. Holder's holding period in our common shares for purposes of making a QEF election. A deemed sale election generally can be made only if the U.S. Holder owns common shares on the first day of our taxable year in which the election is to be effective.
 Alternatively, a U.S. Holder of our common shares may elect to recognize any gain or loss on its common shares on a mark-to-market basis at the end of each taxable year, so long as our common shares are regularly traded on a qualified exchange. The OTCQB Venture Marketplace, on which our common shares currently trade, may not be a qualified exchange for this purpose. Therefore, we cannot provide assurance that our common shares are regularly traded on a qualified exchange for PFIC purposes, and we provide no assurance that our common shares will be regularly traded on a qualified exchange for this or any subsequent year in which we may be a PFIC.
 If a mark-to-market election is made, the excess distribution regime will not apply to amounts received with respect to our common shares from and after the effective time of the election, and any mark-to-market gains or gains on disposition will be treated as ordinary income. Mark-to-market losses and losses on disposition will be treated as ordinary losses to the extent of the U.S. Holder's unrecovered prior net mark-to-market gains. Losses in excess of prior net mark-to-market gains will generally not be recognized. The mark-to-market election must be made by the due date (as may be extended) for filing the U.S. Holder's federal income tax return for the first year in which the election is to take effect. A mark-to-market election applies to all future years of an electing U.S. Holder during which the stock is regularly traded on a qualifying exchange, unless revoked with the IRS's consent.
 The QEF election and mark-to-market election rules are complex. U.S. Holders should consult their tax advisor regarding the availability and procedure for making these elections.
 Special adverse rules apply to U.S. Holders of our common shares for any year in which we are a PFIC and own or dispose of shares in another corporation that is also a PFIC (a "lower-tier PFIC"). A U.S. Holder who owned our common shares while we were a PFIC will be deemed to own its proportionate share of any lower-tier PFIC, and will be subject to U.S. federal income tax on (i) a distribution on the shares of a lower-tier PFIC and (ii) a disposition of shares of a lower-tier PFIC, both as if the U.S. Holder directly held the shares of such lower-tier PFIC. Moreover, a QEF election or mark-to-market election that is made for our common shares would not apply to a lower-tier PFIC. While a separate QEF election may be made for a lower-tier PFIC, we do not undertake to provide the financial information to U.S. Holders that would allow them to make a QEF election for any lower-tier PFIC. A mark-to-market election generally may not be made with respect to a lower-tier PFIC.
 A U.S. Holder who makes a QEF election for our common shares but not for shares of a lower-tier PFIC will be taxable under the excess distribution regime on gain that we recognize on the sale of shares of any such lower-tier PFIC. Any U.S.

 Holder who makes a mark-to-market or deemed sale election for our common shares could be subject to the PFIC rules with respect to income of a lower-tier PFIC, even though the value of such lower-tier PFIC already was subject to tax via mark-to-market or deemed sale adjustments.
 The IRS has issued proposed regulations that, subject to certain exceptions, would treat as taxable certain transfers of PFIC stock by a U.S. Holder that has not made a timely QEF election or mark-to-market election that are generally not otherwise taxed, such as gifts, exchanges pursuant to corporate reorganizations, and transfers at death. Generally, in such cases, the basis of our common shares in the hands of the transferee and the basis of any property received in the exchange for those shares would be increased by the amount of gain recognized. The specific tax effect to the U.S. Holder and the transferee may vary based on the manner in which the common shares are transferred. Each U.S. Holder should consult a tax advisor with respect to how the PFIC rules affect their tax situation prior to transferring PFIC shares.
 Special adverse rules that impact certain estate planning goals could apply to our common shares if we are a PFIC. Special rules apply with respect to the calculation of the amount of the foreign tax credit with respect to excess distributions by a PFIC.
 Each U.S. Holder that has a direct or indirect interest in our common shares for a year for which we were a PFIC, generally would be required to file an IRS Form 8621 ("Form 8621"), if, during such year, the U.S. Holder received distributions or recognized gain with respect to our common shares, or was deemed to receive an indirect distribution from a lower-tier PFIC or to recognize gain on an indirect disposition of lower-tier PFIC stock, or in such other situations as the IRS may require. Form 8621 is also used to make certain elections with respect to PFICs, including a QEF election and a mark-to-market election. Each U.S. Holder should consult its tax advisor regarding these and any other relevant information or other reporting requirements.
 If we are a PFIC in the taxable year in which we pay a dividend or the immediately preceding taxable year, dividends on our common shares will not be "qualified dividend income," and such dividends received by individual U.S. Holders generally will be taxed at ordinary income tax rates, subject to the tax rules that apply to excess distributions from PFICs, as discussed above.
 Sale or Other Disposition of Our Common Shares
 The tax treatment of a sale or other disposition of our common shares by a U.S. Holder will differ based upon whether the PFIC rules apply and whether the U.S. Holder has made any of the elections described above.
 If the excess distribution regime discussed above applies to the sale or disposition of our common shares, the rules regarding the taxation of excess distributions will generally apply upon a sale or other disposition of the common shares.
 If the excess distribution regime discussed above does not apply to the sale or disposition of our common shares, the difference between the amount received and the adjusted tax basis of the common shares will be a gain or loss. If, as usually is the case, the common shares are a capital asset in the hands of the U.S. Holder, such gain or loss will be a capital gain or loss. If the U.S. Holder has made a QEF election with respect to the shares, the adjusted basis will be increased by the U.S. Holder's proportionate share of income and capital gains taken into account each year as a result of the QEF election. If the U.S. Holder has made a mark-to-market election with respect to the shares, the adjusted basis will be increased by the net income recognized on the common shares as a result of the mark-to-market election. Capital gain or loss with respect to common shares generally will be long-term capital gain or loss if the holding period for the shares giving rise to such gain or loss exceeds one year. Under current law, long-term capital gains realized by individual U.S. Holders are taxed at reduced rates. Short-term capital gains are taxed at ordinary income rates. The deductibility of capital losses is subject to significant limitations.
 Distributions
 We do not expect to pay dividends in the foreseeable future. However, subject to the PFIC rules discussed below, a U.S. Holder must include in gross income as dividend income the gross amount of any distribution (including the amount of

 any Canadian withholding tax thereon) paid by the Company out of its current or accumulated earnings and profits (as determined for U.S. federal income tax purposes) with respect to our common shares. A distribution on our common shares in excess of current or accumulated earnings and profits will be treated as a tax-free return of capital to the extent of the U.S. Holder's adjusted basis in such common shares (thus reducing, but not below zero, the adjusted tax basis of such common shares), and thereafter as gain from the sale or exchange of common shares. See "Sale or Other Disposition of Our Common Shares" above.
 If we are a PFIC in the taxable year in which we pay a dividend or the immediately preceding taxable year, dividends received by individual U.S. Holders generally will be taxed at ordinary income tax rates, subject to the rules that apply to excess distributions from PFICs, as discussed above.
 If we are not a PFIC in the taxable year in which we pay a dividend or the immediately preceding taxable year, dividends received by individual U.S. Holders will be taxed to such U.S. Holder at the rates applicable to long-term capital gains as "qualified dividend income" if (i) we are eligible for benefits of the Treaty or (ii) our common shares are readily tradable on an established securities market. We have not determined if we are eligible for such benefits, and our common shares are not currently readily tradable on an established securities market. However, dividend income will not be qualified dividend income (and will be taxed at ordinary income rates) if the U.S. Holder has not held its common shares for at least 61 days during the 121-day period beginning 60 days before the ex-dividend date (or as noted above, if we are a PFIC for the taxable year in which the dividend is paid or in the preceding taxable year).
 Dividends paid to a corporate U.S. Holder will be taxed as ordinary income and will not generally be eligible for the dividends received deduction.
 Surcharge on Net Investment Income; Other Tax Rules
 A surtax of 3.8% (the "unearned income Medicare contribution tax") is imposed on the "net investment income" of certain U.S. citizens and resident aliens, and on the undistributed "net investment income" of certain estates and trusts, in each case in excess of a threshold amount. Net investment income generally includes dividends and net gain from the disposition of property (other than property held in a "non-passive" trade or business). Net investment income is reduced by deductions that are properly allocable to such income. Special rules determine when the unearned income Medicare contribution tax applies to distributions or income with respect to PFICs. U.S. Holders should consult with their U.S. tax advisors concerning how these rules would apply to an investment in our common shares.
 Foreign Currency Transactions
 Generally, amounts received by a U.S. Holder in foreign currency (including dividends paid in foreign currency) will be valued at the rate of exchange on the date of receipt. The subsequent disposition of any foreign currency received (including an exchange for U.S. currency) will generally give rise to ordinary gain or loss should the rate of exchange subsequently change.
 Foreign Tax Credit or Deduction
 A U.S. Holder who pays (or has withheld from distributions) Canadian income tax with respect to the ownership of our common shares may be entitled, at the election of the U.S. Holder, to either receive a deduction or a tax credit for U.S. federal income tax purposes with respect to such foreign tax paid or withheld. Significant and complex limitations apply to the foreign tax credit, including the general limitation that the credit cannot exceed the proportionate share of the U.S. Holder's U.S. income tax liability that the U.S. Holder's "foreign source" income bears to his or its worldwide taxable income. In applying this limitation, the various items of income and deduction must be classified as either "foreign source" or "U.S. source." Complex rules govern this classification process.
 In lieu of a credit, a U.S. Holder who itemizes deductions may elect to deduct all of such holder's foreign taxes in the taxable year. A deduction does not reduce U.S. tax on a dollar-for-dollar basis like a tax credit, but the deduction for foreign taxes is not subject to the same limitations applicable to foreign tax credits. U.S. Holders are urged to consult their own tax advisors regarding the availability of foreign tax credits.

 A U.S. Holder's ability to use foreign tax credits could be adversely affected if we are a PFIC.
 Information Reporting and Backup Withholding
 Certain U.S. Holders are required to report information relating to an interest in our common shares, subject to certain exceptions, by attaching a completed IRS Form 8938, Statement of Specified Foreign Financial Assets, with their tax return for each year in which they hold an interest in our common shares or warrants. U.S. Holders are urged to consult their own tax advisors regarding information reporting requirements relating to their ownership of our common shares.
 Dividend payments made with respect to our common shares and proceeds from the sale or other disposition of our common shares may be subject to information reporting requirements and to U.S. backup withholding.
 In general, backup withholding will apply, currently at a rate of 24%, with respect to reportable payments made to a U.S. Holder unless (i) the U.S. Holder is a corporation or other exempt recipient, and if required, demonstrates such exemption, or (ii) the U.S. Holder furnishes the payor with a taxpayer identification number on IRS Form W-9 in the manner required, certifies under penalty of perjury that such U.S. Holder is not currently subject to backup withholding and otherwise complies with the backup withholding requirements.
 Backup withholding is not an additional tax. Rather, the amount of any backup withholding imposed on a payment to a holder will be allowed as a refund or a credit against such holder's U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

 ITEM 6. [RESERVED]
 ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes appearing elsewhere in this Annual Report. This discussion and analysis contains forward-looking statements that involve risks, uncertainties, and assumptions. See "Cautionary Note Regarding Forward-Looking Statements." Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including, but not limited to, those set forth in "Item 1A. Risk Factors" and elsewhere in this Annual Report.
 The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our Consolidated Financial Statements and accompanying notes included in Item 8 of this Annual Report. This Management's Discussion and Analysis (this "MD&A") has been prepared based on information known to management as of March 19, 2024. This MD&A is intended to help the reader understand the consolidated audited financial statements of the Company.
 All currency amounts are expressed in thousands of U.S. dollars, except per share and common share amounts, unless otherwise noted.
 OVERVIEW AND OUTLOOK
 Our primary focus has been and continues to be the engineering, permitting, licensing, construction, and operation of the Demonstration Plant at the planned location site in Upton, Wyoming. If successful, this Demonstration Plant will show that our propriety extraction technology is able to process and separate certain REEs from high grade sample materials extracted from our Bear Lodge REE Project in a more efficient and economical manner than traditional processing methods and will serve as a precursor to inform the design and estimated cost for a future full-scale production facility.
 During 2023, the Company, along with the other consortium members, continued their work on the Demonstration Plant, and this work is expected to continue through the project's expected completion date in 2025. In December 2022, the

 Demonstration Plant achieved its final engineering design milestone marking the completion of the DoE's first go/no-go decision point. The completion of this milestone was a gating event for the DoE's continued funding of the project as provided for in the 2021 award grant. A second milestone was achieved with the completion of permitting activities in the fourth quarter of 2023, allowing for the Demonstration Plant's construction. Operations to process and separate the REE from the stockpiled mineral sample are expected to follow the completion of the Demonstration Plant's construction for an additional 12-to 15-month period.
 In June 2023, the Company entered into a Funding Agreement with the WEA for its previously announced award of a $4,400 grant from the WEA to be used toward the advancement of the Demonstration Plant. This award, along with the funds raised from the Company's 2021 rights offering, will be used to fund the Company's fifty percent (50%) share of the Demonstration Plant's originally estimated cost of approximately $43,800 with the other fifty percent of the funding coming from the DoE. Through December 31, 2023, the Company had paid a total of $15,700 toward its share of the expected cost of the Demonstration Plant (see Note 4 to our Consolidated Financial Statements for a more complete discussion). As of December 31, 2023, the Company had met the conditions allowing for the invoicing of $2,000 of the $4,400 WEA grant total but no grant funds had yet been received. This $2,000 was subsequently received on January 31, 2024 (see Note 14 – Subsequent Events).
 Since inception, the General Atomics-led consortium has seen increases in the Demonstration Plant project costs, including expected final equipment costs, due to, among other factors, inflation. Accordingly, the project team has commenced discussions with the DoE and other government agencies regarding further cost-sharing opportunities to offset the increase in the anticipated project costs and further project objectives. In part to fund the Company's share of these cost increases, the Company announced, during December 2023, its intention to launch a rights offering to raise approximately $36,000 in gross proceeds. In March 2024, the Company completed the rights offering for gross proceeds of approximately $35,800 in which each holder of the Company's common shares as of the record date of December 15, 2023 was eligible to participate. The proceeds from this rights offering will be used to progress the Company's business strategy to support commercialization and fund activities to support the advancement of the Bear Lodge REE Project, which includes funding the operation of the Demonstration Plant for a period of time that is expected to be sufficient to provide the information to support a commercialization decision, acquiring real property, updating the mineral resource model and technical reports, and advancing permitting, environmental support, and basic engineering, as well as for other general corporate purposes. Even with these funds, however, the Company will still require substantial additional funds for the full permitting, development, and buildout of the Bear Lodge REE Project. Ultimately, in the event the Company cannot secure additional financial resources, or complete a strategic transaction in the longer term, the Company may need to curtail or suspend its operational plans regarding the Bear Lodge REE Project or other initiatives, or potentially liquidate its business interests, and investors may lose all or part of their investment.
 RESULTS OF OPERATIONS
 Year Ended December 31, 2023 Compared with the Year Ended December 31, 2022
 Summary
 Our consolidated net loss for the year ended December 31, 2023 was $8,996, or $0.04 per share, compared with our consolidated net loss of $9,426, or $0.04 per share, for the same period in 2022. See our discussion below for the primary drivers of this change. As an exploration stage company, we had no properties in production and generated no revenues during either year.
 Exploration and Evaluation
 Our exploration and evaluation costs totaled $8,242 for the year ended December 31, 2023, compared with $4,155 for the same period in 2022. This increase of $4,087 was largely attributable to the activities associated with our Bear Lodge REE Project and the Demonstration Plant as work progressed under the Cost Share Agreement (as defined below). See Note 4 to the Consolidated Financial Statements for a more complete discussion of this Cost Share Agreement.

 Corporate Administration
 Our corporate administration costs decreased by $2,278 on a comparative year-over-year basis, falling from $5,106 in the year ended December 31, 2022 to $2,828 for the year ended December 31, 2023. This decrease was largely driven by a decrease in our stock-based compensation costs of $2,453.
 Interest Income
 For the years ended December 31, 2023 and 2022, the Company generated interest income of $476 and $258, respectively, on investments of its excess cash balances. The increase in 2023 interest income was primarily the result of the substantially higher short-term interest rates that existed during the year, partially offset by the lower average cash balances available for investment during the year ended December 31, 2023.
 Grant Income
 During December 2023, the Company recognized grant income of $2,000 with the achievement of the first milestone under the WEA Funding Agreement. There were no such transactions for the year ended December 31, 2022. See Note 5 to the Consolidated Financial Statements for a more complete discussion of the WEA Funding Agreement.
 Accretion Expense
 For the years ended December 31, 2023 and 2022, we recorded accretion expense of $283 and $284, respectively, related to the Company's option to repurchase approximately 640 acres of non-core real property in Wyoming for not less than $1,200 or greater than $1,850 in the form of cash, common shares of the Company, or a combination of cash and common shares of the Company. Accretion expense is recorded each reporting period to increase the Repurchase Option liability to the maximum exercise price of $1,850, less any annual option payments of $25. See Note 8 to the Consolidated Financial Statements for a more complete discussion of the Repurchase Option.
 FINANCIAL POSITION, LIQUIDITY AND CAPITAL RESOURCES
 Operating Activities
 Net cash used in operating activities increased by $2,307, rising to $11,706 for the year ended December 31, 2023 from $9,399 for the year ended December 31, 2022. This change was largely attributable to the $2,300 increase in cash advances paid under the Cost Share Agreement during the year ended December 31, 2023 as compared to the year ended December 31, 2022. For the years ended December 31, 2023 and 2022, the Company advanced funds of $9,000 and $6,700, respectively, under the Cost Share Agreement for work on the Demonstration Plant.
 Investing Activities
 Net cash used in investing activities of $4 for the year ended December 31, 2023 resulted from a $12 sale of non-essential equipment, offset by a $16 purchase of equipment. There were no similar transactions during the year ended December 31, 2022.
 Financing Activities
 During the year ended December 31, 2023, the Company received $31 from the exercise of 455,000 stock options. There was no cash received from stock option exercises during 2022 as all stock option exercises were net share settled. Additionally, during 2023 and 2022, the Company made payments of $25 each year to extend the Repurchase Option.
 Liquidity and Capital Resources
 At December 31, 2023, we had a working capital balance of $7,809 which represented a decrease of $9,819 from our December 31, 2022 working capital balance of $17,628. This decrease was largely the result of amounts paid by the

 Company during the year ended December 31, 2023 under the Cost Share Agreement of $9,000 and for the payment of other ongoing expenses being partially offset by the $2,000 increase in the WEA grant receivable balance.
 In June 2023, the Company entered into the WEA Funding Agreement for its previously announced award of a $4,400 grant from the WEA to be used toward the advancement of the Demonstration Plant. The WEA grant is a cost-reimbursement award that is available to the Company for the reimbursement of Demonstration Plant expenses. As of December 31, 2023, the WEA had been invoiced for the first $2,000 of the $4,400 grant total for the achievement of the first milestone under the WEA Funding Agreement. The Company received payment of this $2,000 in January 2024. The remaining $2,400, which is conditioned on the achievement of future milestones, will be invoiced to the WEA upon achievement of those milestones.
 Inclusive of amounts already advanced of $15,700 through December 31, 2023, the Company's share of the total costs under the Cost Share Agreement are expected to exceed $22,000 over the life of the Demonstration Plant project. As a result, the project team has commenced discussions with the DoE and other government agencies regarding further cost-sharing opportunities to offset the increase in the anticipated project cost and further project objectives. To address these further funding needs, the Company announced on December 5, 2023 its intention to launch a rights offering to raise approximately $36,000 in gross proceeds. In March 2024, the Company completed the rights offering for gross proceeds of approximately $35,800 in which each holder of the Company's common shares as of the record date of December 15, 2023 was eligible to participate.
 With the funds raised from the 2024 rights offering, the Company will have sufficient funds to complete construction and operation of the Demonstration Plant; however, even with these funds and the expected receipt of the remaining WEA grant monies, the Company will still require substantial additional funds to complete fully the permitting and licensing, and ultimate construction and operation of a commercial mine and plant for the Bear Lodge REE Project. Ultimately, in the event the Company cannot secure additional financial resources, or complete a strategic transaction in the longer term, the Company may need to curtail or suspend its operational plans regarding the Bear Lodge REE Project or other initiatives, or potentially liquidate its business interests, and investors may lose all or part of their investment.
 Off-Balance Sheet Arrangements
 We have no off-balance sheet arrangements required to be disclosed in this Annual Report.
 Contractual Obligations
 Cost Share Agreement – Related Party
 On November 30, 2021, the Company and General Atomics entered into a Cost Share Funding Assumption Agreement (the "Cost Share Agreement") pursuant to which the Company agreed to assume and pay for certain costs incurred by General Atomics and the consortium for the design, construction, and operation of a rare earth separation and processing Demonstration Plant near the Bear Lodge REE Project in Upton, Wyoming.
 As previously discussed, in January 2021, the DoE announced that a consortium of companies, which includes the Company, led by General Atomics, an affiliate of Synchron, and certain of its affiliates, and LNV, an Ardurra Group, Inc. company, as engineering and construction subcontractor, was selected for a potential financial award in the amount of $21,900 for the engineering, construction and operation of a rare earth separation and processing Demonstration Plant. The DoE award was finalized through a cooperative agreement dated October 1, 2021 (the "Cooperative Agreement") between General Atomics and the DoE with respect to the engineering, permitting, and licensing, construction, and operation of the Demonstration Plant. The Cooperative Agreement provides that up to approximately $43,800 in allowable costs for the Demonstration Plant would be funded on a cost-share basis, 50% by the DoE and 50% by a non-federal entity.
 Pursuant to the terms of the Cost Share Agreement, the Company is obligated to make payments totaling $21,900 to General Atomics, as leader of the consortium, for its share of the assumed costs for the Demonstration Plant, $15,700 of which had been paid through December 31, 2023.

 The term of the Cost Share Agreement will continue until the date of completion of the Demonstration Plant, unless terminated earlier by either party. Either party may terminate the Cost Share Agreement immediately upon written notice to the other party if any of the following events occurs: (a) the Cooperative Agreement is terminated for any reason prior to the completion of the Demonstration Plant; (b) the other party commits a material breach of its obligations under the Cost Share Agreement and fails to cure such breach within 30 days; or (c) the other party makes an assignment for the benefit of its creditors, files a petition in bankruptcy, is adjudicated insolvent or bankrupt, or commences any insolvency or bankruptcy proceedings. Upon any early termination of the Cost Share Agreement, the Company must pay for all costs incurred by or on behalf of General Atomics to wind down the Demonstration Plant other than any allowable costs for such wind-down paid for by the DoE.
 Intellectual Property Rights – Related Party
 During October 2017, the Company and Synchron executed an intellectual property rights agreement, whereby Synchron received rights to use and improve the Company's intellectual property relating to the Company's patents and related technical information. The Company retains the right to use any such improvements. See "Item 1A. Risk Factors" of this Annual Report.
 Land Purchase Option
 On October 25, 2021, the Company and Whitelaw Creek LLC, a Wyoming limited liability company ("Whitelaw Creek"), entered into an amendment (the "Amendment") to the asset purchase agreement dated October 20, 2016 between the Company and Whitelaw Creek (the "Asset Purchase Agreement"). The Amendment modified certain provisions of the Asset Purchase Agreement related to the terms and conditions of the Company's option to repurchase (the "Repurchase Option") approximately 640 acres of non-core real property located in Crook County, Wyoming, that is under consideration for a waste rock facility for the Bear Lodge REE Project. Pursuant to and subject to the terms of the Amendment, among other things, the term of the Repurchase Option (which was to expire on October 26, 2021) was extended for up to three additional years, subject to annual option extension payments from the Company to Whitelaw Creek of $25 in cash per year (each, a "Repurchase Option Extension Payment"); and the exercise price of the Repurchase Option was increased from $1,000 to a price to be determined by a mutually agreed upon real estate appraiser (the "Repurchase Price"), provided that (i) the Repurchase Price must not be less than $1,200 or greater than $1,850 and (ii) any Repurchase Option Extension Payments paid by the Company to Whitelaw Creek must be credited toward the Company's payment of the Repurchase Price if the Repurchase Option is later exercised. In October 2023, the Company made the $25 Repurchase Option Extension Payment to Whitelaw Creek to extend the term of the Repurchase Option through October 26, 2024.
 CRITICAL ACCOUNTING POLICIES

 For a summary of our significant accounting policies, including those discussed below, see Note 3 to our Consolidated Financial Statements.

 CRITICAL ACCOUNTING ESTIMATES
 The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. The amounts which involve significant estimates include reclamation obligations and income tax.
 Reclamation Obligations
 Our mining and exploration activities are subject to various laws and regulations, including legal and contractual obligations to reclaim, remediate, or otherwise restore properties at the time the property is removed from service. Reclamation obligations are recognized when incurred and recorded as liabilities at fair value. The reclamation obligation is based on when spending for an existing disturbance will occur. We reclaim the disturbance from our exploration

 programs on an ongoing basis and, therefore, the portion of our reclamation obligation corresponding to our exploration programs will be settled in the near term and is classified as a current liability. The remaining reclamation associated with environmental monitoring programs is classified as a long-term liability; however, because we have not declared proven and probable reserves as defined under Item 1300 of Regulation S-K, the timing of these reclamation activities is uncertain as the reclamation areas will be utilized once the project is operating. For exploration stage properties that do not qualify for asset capitalization, the costs associated with the obligation are charged to operations. For development and production stage properties, the costs are added to the capitalized costs of the property and amortized using the units-of-production method. We review, on a quarterly basis, unless otherwise deemed necessary, the reclamation obligation associated with our properties.
 Our Bear Lodge REE Project reclamation obligation is secured by a surety bond held for the benefit of the state of Wyoming in an amount determined by the applicable federal or state regulatory agency. We also maintain a surety bond for the reclamation of the Demonstration Plant property.
 Accounting for reclamation and remediation obligations requires management to make estimates unique to each mining and processing operation of the future costs the Company expects to incur to complete the reclamation and remediation work required to comply with existing laws and regulations. These estimates require considerable judgment and are sensitive to changes in underlying inputs and assumptions. Such changes, including, but not limited to, (i) changes to environmental laws and regulations, which could increase the scope and extent of work required, (ii) changes in the timing of reclamation and remediation activities, which could occur over an extended future period and (iii) changes in the methods and technology utilized to settle reclamation and remediation obligations, could have a material impact on our business, financial condition, results of operations and cash flows.

 Income Taxes
 The Company applies the provisions of Financial Accounting Standards Board Accounting Standard Codification ("ASC") 740 Income Taxes. The Standard requires an asset and liability approach for financial accounting and reporting for income taxes and the recognition of deferred tax assets and liabilities for the temporary differences between the financial reporting basis and tax basis of the Company's assets and liabilities at enacted tax rates expected to be in effect when such amounts are realized or settled. Due to losses from inception, the Company has no tax liability. Currently, the Company has no deferred taxes arising from temporary differences between income for financial reporting and income tax purposes as a full valuation allowance has been recorded against the deferred tax assets.
 The Company classifies tax-related penalties and net interest on income taxes as income tax expense. As of December 31, 2023 and 2022, no income tax expense had been incurred or accrued.

 New Accounting Pronouncements

 As of December 31, 2023, the Company had adopted all accounting pronouncements affecting the Company.

 ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 Not applicable.

 ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
 The following Consolidated Financial Statements and Reports of Independent Registered Public Accountants are filed as part of this Item 8 and are included in this Annual Report. Certain prior year amounts have been reclassified to conform to the current year presentation.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 To the Board of Directors and
Stockholders of Rare Element Resources, Ltd.
 Opinion on the Financial Statements
 We have audited the accompanying consolidated balance sheets of Rare Element Resources Ltd. (the Company) as of December 31, 2023 and 2022, and the related consolidated statements of operations, shareholders' equity (deficit), and cash flows for each of the years in the two-year period ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.
 Basis for Opinion
 These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
 We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.
 Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
 Critical Audit Matters
 The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
 Cost Share Agreement – Refer to Note 4 to the financial statements
 As discussed in Note 4 to the financial statements, the Company is a member of a consortium of companies, led by General Atomics, a related party, who are developing a Demonstration Plant (the project) that will process high-grade rare-earth material. In connection with the arrangement, the Company entered into a cost share agreement with General Atomics, in which the Company agreed to assume and pay for 50% of those costs incurred by, and on behalf of, General Atomics, as leader of the consortium, for the project.
 We consider management's assessment and accounting of the cost share agreement as a significant audit matter because of the significant judgements required by management to determine the activity completed in accordance with the agreements. This required a high degree of auditor judgement and an increased extent of effort to address these matters.
 Addressing the matter involved gaining an understanding of the process to account for the cost share agreement. We obtained and interpreted the cost share agreement and subcontracts to ensure the amounts were consistently applied. We evaluated management's analysis and compared that to applicable accounting guidance. Finally, we obtained the Company's fund flows and examined the costs used in their calculation to ensure they were in accordance with the agreements.

 1. NATURE OF OPERATIONS
 Rare Element Resources Ltd. ("we," "us," "Rare Element" or the "Company") was incorporated under the laws of the Province of British Columbia, Canada, on June 3, 1999.
 Rare Element holds a 100 % interest in the Bear Lodge rare earth elements project (the "Bear Lodge REE Project") located near the town of Sundance in northeast Wyoming. The Bear Lodge REE Project consists of several large, disseminated rare earth elements ("REE") deposits that comprise one of the highest-grade REE deposits identified in North America. In addition, to neodymium-praseodymium ("NdPr"), the Bear Lodge REE Project has a favorable distribution of a number of other critical rare earth elements. The Company also holds a 100 % interest in the Sundance Gold Project that is adjacent to the Bear Lodge REE Project and contains a historical inferred mineral resource primarily composed of three gold targets within the area of the Bear Lodge Property. Given the Company's longstanding focus on the Bear Lodge REE Project and the current interest in REE, the advancement of the Sundance Gold Project has been on hold since 2011 and will likely remain so for the foreseeable future.
 The Company is currently focused on the advancement of a rare earth processing and separation demonstration-scale plant (the "Demonstration Plant") project. In January 2021, a consortium of companies, of which the Company is a part, received notice from the Department of Energy ("DoE") that the consortium had been selected for negotiation of a potential financial award for the engineering, construction and operation of a rare earth separation and processing Demonstration Plant. The consortium of companies is led by General Atomics, an affiliate of Synchron, the Company's majority shareholder, and includes certain of General Atomics' affiliates, and LNV, an Ardurra Group, Inc. company, as engineering and construction subcontractor. A formal proposal was submitted by the consortium in response to a published Funding Opportunity Announcement in mid-2020 for the construction and operation of a rare earth separation and processing demonstration plant utilizing proprietary technology to produce commercial-grade products. The DoE finalized the award, and an agreement was executed by the DoE's grants/agreement officer on September 27, 2021, with an effective date of October 1, 2021. The Company, as a subrecipient of the award, along with the other consortium members, commenced work on the planning and design of the Demonstration Plant project in November 2021, with the Company's contractual arrangement with General Atomics finalized in December 2021. The DoE funding is in the amount of $ 21,900 and represents approximately one -half of the originally estimated costs for the Demonstration Plant. The Demonstration Plant will process already stockpiled high-grade sample materials from the Bear Lodge REE Project.

 To address the Company's funding needs, in December 2021, the Company completed a rights offering for gross proceeds of approximately $ 25,400. The Company is using the net proceeds from the rights offering for the permitting, licensing, engineering, and planned construction, and operation of the Demonstration Plant near the Company's Bear Lodge REE Project. The previously noted $ 21,900 financial award from the DoE was expected to fund approximately one -half of the originally expected total cost of the Demonstration Plant project, with the balance of the required funding being provided by the Company utilizing the proceeds from the rights offering, the $ 4,400 grant from the Wyoming Energy Authority (the "WEA") as discussed more fully in Note 5, and other funding sources, as necessary. Due to inflationary pressures, the initial Demonstration Plant project cost estimate of $ 43,800 has increased and as a result on December 5, 2023, the Company announced its intention to launch a rights offering to raise approximately $ 36,000 in gross proceeds. In March 2024, the Company completed the rights offering for gross proceeds of approximately $ 35,800 in which each holder of the Company's common shares as of the record date of December 15, 2023 was eligible to participate. The Company plans to use the net proceeds from the rights offering to progress the Company's business strategy to support commercialization and fund activities to support the advancement of the Bear Lodge REE Project, which includes funding the operation of the Demonstration Plant for a period of time that is expected to be sufficient to provide the information to support a commercialization decision, acquiring real property, updating the mineral resource model and technical reports, and advancing permitting, environmental support, and basic engineering, as well as for other general corporate purposes. Ultimately, in the event the Company cannot secure additional financial resources, or complete a strategic transaction in the longer term, the Company may need to curtail or suspend its operational plans regarding the Demonstration Plant or other initiatives, or potentially liquidate its business interests, and investors may lose all or part of their investment.

 (all amounts stated in thousands of U.S. dollars except share and per share amounts)

 During 2022 and 2023, the Company continued its work on the Demonstration Plant project. This work is expected to continue through the Demonstration Plant's expected completion date in 2025. In December 2022, the Demonstration Plant achieved its final engineering design milestone marking the completion of the DoE's first go/no-go decision point. A second go/no-go gating milestone was achieved in December 2023 with the issuance by the DoE of a Project Continuation Notice, allowing for the construction of the Demonstration Plant. The completion of these milestones were each gating events for the DoE's continued funding as provided for in the 2021 award grant. With the completion of this second gating event, the Demonstration Plant's construction is now underway and is expected to be completed in mid-2024. Operations to process and separate the REE from the sample materials are expected to follow the completion of the Demonstration Plant's construction for an additional 12 -to- 15 -month period.

 The Company has incurred losses since its inception, and further losses are anticipated in the development of its business. As of December 31, 2023, the Company had cash and cash equivalents of $ 3,633. During the year ended December 31, 2023, we consumed cash of $ 11,706, of which approximately $ 9,000 was used for the payment of costs associated with the Demonstration Plant project, with the remainder having been used for the payment of the Company's general and administrative expenses and other ongoing costs of sustaining its properties and mining claims.
 2. BASIS OF PRESENTATION
 Principles of Consolidation
 These consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles ("GAAP") and are inclusive of the accounts of Rare Element Resources Ltd. and its directly held wholly owned subsidiary, Rare Element Resources, Inc. All numbers in the consolidated financial statements are presented in U.S. dollars (in thousands), unless otherwise denoted.
 Reclassifications

 Certain amounts for the year ended December 31, 2022 have been reclassified to conform to the 2023 presentation. Total assets, liabilities, equity, and net loss did not change for the prior periods due to the reclassifications.

 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 Use of Estimates
 The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. The amounts that involve significant estimates include our reclamation obligations and stock-based compensation.
 Cash and Cash Equivalents
 Cash and cash equivalents consist of cash and liquid investments with an original maturity of three months or less. At December 31, 2023 and 2022, cash and cash equivalents consisted of $ 3,633 and $ 15,523, respectively, of funds held in bank and investment accounts with financial institutions in the United States.
 The Company continually monitors its cash positions with, and the credit quality of, the financial institutions with which it invests. The Company maintains balances in various U.S. financial institutions in excess of U.S. federally insured limits.

 (all amounts stated in thousands of U.S. dollars except share and per share amounts)

 Restricted Cash
 The Company periodically maintains cash deposits that are held and earmarked for a specific purpose. At December 31, 2023, the Company had $ 186 in restricted cash for amounts held by a third party as security for a surety bond for our Demonstration Plant.
 Mineral Properties and Exploration and Evaluation Costs
 Mineral property acquisition costs, including indirectly related acquisition costs, are capitalized when incurred. Acquisition costs include cash consideration and the fair market value of the Company's common shares (the "Common Shares") issued as consideration. Properties acquired under option agreements, whereby payments are made at the sole discretion of the Company, are capitalized as mineral property acquisition costs at such time as the payments are made. Exploration costs are expensed as incurred. When it is determined that a mining deposit can be economically and legally extracted or produced based on established proven and probable mineral reserves under Item 1300 of Regulation S-K, development costs related to such reserves and incurred after such determination will be considered for capitalization. The establishment of proven and probable reserves is based on results of feasibility studies. Upon commencement of commercial production, capitalized costs will be amortized over their estimated useful lives or units of production, whichever is a more reliable measure. Capitalized amounts relating to a property that is abandoned or otherwise considered uneconomic for the foreseeable future will be written off.
 The Company currently has no proven and probable reserves, and you are specifically cautioned not to assume that any part or all of our mineral resources will ever be converted into mineral reserves, as defined by the SEC or NI 43-101. See "Item 1A. Risk Factors" of this Annual Report.
 Reclamation Obligations
 The Company's mining and exploration activities are subject to various laws and regulations, including legal and contractual obligations to reclaim, remediate, or otherwise restore properties at the time the property is removed from service. Reclamation obligations are recognized when incurred and recorded as liabilities at fair value. The reclamation obligation is based on when spending for an existing disturbance will occur. The Company reclaims the disturbance from its exploration programs on an ongoing basis; therefore, the portion of its reclamation obligation corresponding to its exploration programs expected to be settled in the near term is classified as a current liability. The remaining reclamation associated with environmental monitoring programs is classified as a long-term liability; however, because we have not declared proven or probable mineral reserves as defined under Item 1300 of Regulation S-K, the timing of these reclamation activities is uncertain as the reclamation areas will only be utilized once the Bear Lodge REE Project is operating. For exploration stage properties that do not qualify for asset capitalization, the costs associated with the reclamation obligation are charged to operations. For development and production stage properties, the costs are added to the capitalized costs of the property and amortized using the units-of-production method. We review, on a quarterly basis, unless otherwise deemed necessary, the reclamation obligation associated with our Bear Lodge Property.
 The Company's reclamation obligation is secured by surety bonds held for the benefit of the state of Wyoming in amounts determined by the applicable federal or state regulatory agencies. The Company's reclamation obligation, which increased from $ 132 as of December 31, 2022 to $ 182 as of December 31, 2023, was due to a revision in this estimate.
 Depreciation
 Depreciation is computed using the straight-line method. The Company depreciates computer equipment, furniture and fixtures and geological equipment over a period of three to ten years. The Company depreciates vehicles over a period of five years.

 (all amounts stated in thousands of U.S. dollars except share and per share amounts)

 Stock-based Compensation
 The fair value of stock-based compensation awards is measured at the date of grant and amortized over the requisite service period, which is generally the vesting period, with a corresponding increase in additional paid-in capital. The Company uses the Black-Scholes option valuation model to calculate the fair value of awards granted.
 In the case of a share-based compensation award that is either cancelled or forfeited prior to vesting, the amortized expense associated with the unvested awards is reversed. The Company has elected to account for forfeitures as they occur.
 Income Taxes
 The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under the asset and liability method, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized if it is more likely than not that the entire or some portion of the deferred tax asset will not be recognized.
 Loss per Share
 Loss per share is computed using the weighted average number of shares outstanding during the period. To calculate diluted loss per share, the Company uses the treasury stock method and the if-converted method. Diluted loss per share is not presented, as the effect on the basic loss per share would be anti-dilutive. At December 31, 2023 and 2022, we had 4,725,000 and 4,160,000 of potentially dilutive securities, respectively, related to outstanding stock options.
 Fair Value
 GAAP defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price) and establishes a fair-value hierarchy that prioritizes the inputs used to measure fair value using the following definitions (from highest to lowest priority):

 Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

 Level 2 — Observable inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data by correlation or other means.

 Level 3 — Prices or valuation techniques requiring inputs that are both significant to the fair-value measurement and unobservable.

 (all amounts stated in thousands of U.S. dollars except share and per share amounts)

 Financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used in such measurements by major security type as of December 31, 2023 and 2022 are presented in the following table:

 4. RELATED PARTY
 Cost Share Agreement with General Atomics
 In January 2021, a consortium of companies, of which the Company is a part, received notice from the DoE that the consortium had been selected for negotiation of a potential financial award for the engineering, construction, and operation of the Demonstration Plant. The consortium of companies is led by General Atomics, an affiliate of Synchron (the Company's majority shareholder), and includes certain of General Atomics' affiliates, and LNV, an Ardurra Group, Inc. company, as engineering and construction subcontractor. A formal proposal was submitted by the consortium in response to a published Funding Opportunity Announcement in mid-2020 for the construction and operation of the Demonstration Plant utilizing proprietary technology to produce commercial-grade products. The DoE's share of the Demonstration Plant project funding is $ 21,900 and represents approximately one -half of the total originally estimated costs for the project. The Demonstration Plant is planned to process already stockpiled high-grade sample materials from the Bear Lodge REE Project. The DoE agreement was executed by the DoE's grants/agreement officer on September 27, 2021, with an effective date of October 1, 2021. The DoE award was finalized through a cooperative agreement dated October 1, 2021 (the "Cooperative Agreement") that was awarded by the DoE for the Demonstration Plant. The Cooperative Agreement provides that up to approximately $ 43,800 in allowable costs for the Demonstration Plant would be funded on a cost-share basis, 50 % by the DoE and 50 % by a non-federal entity.
 On November 30, 2021, the Company and General Atomics entered into a Cost Share Funding Assumption Agreement (the "Cost Share Agreement") pursuant to which the Company agreed to assume and pay for certain costs incurred by, and on behalf of, General Atomics for the design, construction, and operation of the Demonstration Plant near the Bear Lodge REE Project in Upton, Wyoming.

 (all amounts stated in thousands of U.S. dollars except share and per share amounts)

 Pursuant to the terms of the Cost Share Agreement, the Company has made payments to General Atomics, as leader of the consortium, totaling $ 15,700 through December 31, 2023, for Company-assumed costs for the Demonstration Plant, with the number and amount of additional payments to be subject to the mutual written agreement of the parties.
 The term of the Cost Share Agreement will continue until the date of completion of the Demonstration Plant project, unless terminated earlier by either party. Either party may terminate the Cost Share Agreement immediately upon written notice to the other party if any of the following events occurs: (a) the Cooperative Agreement is terminated for any reason prior to the completion of the Demonstration Plant project; (b) the other party commits a material breach of its obligations under the Cost Share Agreement and fails to cure such breach within 30 days; or (c) the other party makes an assignment for the benefit of its creditors, files a petition in bankruptcy, is adjudicated insolvent or bankrupt, or commences any insolvency or bankruptcy proceedings. Upon any early termination of the Cost Share Agreement, the Company must pay for all costs incurred by or on behalf of General Atomics to wind down the Demonstration Plant project other than any allowable costs for such wind-down paid for by the DoE.

 5. WYOMING ENERGY AUTHORITY GRANT
 In June 2023, the Company, and the WEA entered into a Funding Agreement (the "WEA Funding Agreement") pursuant to which the WEA agreed to fund, subject to certain conditions, a $ 4,400 grant to the Company, the proceeds of which are to be used for the Demonstration Plant. Pursuant to the WEA Funding Agreement, the grant is to be paid upon the WEA's receipt of invoices from the Company detailing its actual expenses relating to the Demonstration Plant (half of which funds will be allocated to two milestone periods during the development process), less a 10 % (or $ 440) retainer, the payment of which is conditioned upon the WEA's receipt following the commencement of the Demonstration Plant's operations of an invoice and the Company's final executive summary report in a form to be approved by the WEA. Pursuant to the WEA Funding Agreement, the funding for the Demonstration Plant will be provided to the WEA from the Energy Resources Council (the "ERC") and is further conditioned upon the availability of government funds that are appropriated or allocated for the payment of the grant and which may be limited for any reason, including congressional, legislative, gubernatorial, or administration action.

 (all amounts stated in thousands of U.S. dollars except share and per share amounts)

 The WEA Funding Agreement will terminate when the funding has been fully disbursed, but no later than December 31, 2025, unless terminated sooner by either party in accordance with the terms of the WEA Funding Agreement. The WEA Funding Agreement may be terminated (i) by either party if the WEA does not receive the requested funding from the ERC or if the grant funds are not allocated or available for the continued performance of the WEA Funding Agreement, or (ii) by the WEA immediately for cause if the Company fails to perform in accordance with the terms of the WEA Funding Agreement.

 The Company received payment in January 2024 of the $ 2,000 grant receivable balance at December 31, 2023. The remaining $ 2,400 of the $ 4,400 grant total, which is conditioned on the achievement of other, future milestones, will be invoiced to the WEA once those milestones have been achieved (expected in 2024).
 Because there is no specific guidance under U.S. GAAP that addresses the recognition and measurement of government assistance received by non-government entities, the Company has elected to account for the WEA grant by analogy to the guidance provided under U.S. GAAP for government assistance to non-business entities. Under this guidance, any recognition of the grant is deferred and only gets recorded in the grantee's financial statements if and when the applicable gating condition(s) have been substantially met. Accordingly, the Company has only recognized in its December 31, 2023 financial statements the $ 2,000 associated with the achievement of the first milestone.
 6. LEASES
 The Company accounts for leases in accordance with ASC 842 – Leases. This accounting standard requires all lessees to record the impact of leasing contracts on the balance sheet as a right to use asset and corresponding liability. This is measured by taking the present value of the remaining lease payments over the lease term and recording a right to use asset and corresponding lease obligation for lease payments. Rent expense is realized on a straight-line basis and the lease obligation is amortized based on the effective interest method. The amounts recognized reflect the present value of the remaining lease payments for all leases that have a lease term greater than 12 months. The discount rate used is an estimate of the Company's incremental borrowing rate based on information available at lease commencement in determining the present value of lease payments.
 In considering the lease asset value, the Company considers fixed or variable payment terms, prepayments, and options to extend, terminate or purchase. Renewal, termination, or purchase options affect the lease term used for determining lease asset value only if the option is reasonably certain to be exercised.
 Effective September 21, 2021, the Company entered into a lease agreement for real property, including land and buildings in Upton, Wyoming for the Demonstration Plant. The lease is a 12 -month lease with annual renewal terms. During June 2023, the lease was renewed, extending the termination date to September 30, 2024. The agreement, which is classified as an operating lease, generally provides for base rent, and requires the Company to pay all insurance, personal property taxes on any structure or improvements made by the Company and other maintenance costs. The lease agreement provides for an annual cost of living adjustment, but contains no residual value guarantees or restrictive covenants. For purposes of the following table, payments under the lease are assumed to run through September 30, 2025, the end of the lease renewal period most closely following the completion of Demonstration Plant operations. If the completion of the Demonstration Plant operations extends past September 2025, the Company may seek to extend the lease term accordingly.

 (all amounts stated in thousands of U.S. dollars except share and per share amounts)

 Total future minimum lease payments as of December 31, 2023 were as follows:

 For the years ended December 31, 2023 and 2022, $ 96 and $ 85, respectively, were included in operating cash flows for amounts paid for operating leases.
 As of December 31, 2023 and 2022, the weighted average lease terms for the Company's one operating lease were 1.75 years and 2.75 years (including renewal options), respectively, and the weighted average discount rate was estimated at 12 % for both years.

 7. MINERAL PROPERTIES
 Bear Lodge Property, Wyoming, USA
 The Company, through its wholly owned subsidiary, Rare Element Resources, Inc., holds a 100 % interest in 499 unpatented mining claims located on land administered by the USFS and a repurchase option (see Note 6) on approximately 640 acres ( 257 hectares) of fee property, together which contain (1) the Bear Lodge REE Project that contains REE mineralization; and (2) the Sundance Gold Project that contains gold mineralization. The property is situated in the Bear Lodge Mountains of Crook County, in northeast Wyoming.

The Company evaluates the recoverability of the carrying value of equipment when events and circumstances indicate that such assets might be impaired. No impairment charges were recorded during the years ended December 31, 2023 and 2022.
 Land
 On October 25, 2021, the Company and Whitelaw Creek LLC, a Wyoming limited liability company ("Whitelaw Creek"), entered into an amendment (the "Amendment") to the asset purchase agreement dated October 20, 2016 between the Company and Whitelaw Creek (the "APA"). The Amendment modified certain provisions of the APA related to the terms and conditions of the Company's option to repurchase (the "Repurchase Option") approximately 640 acres of non-core real property located in Crook County, Wyoming, that is under consideration for a stockpile facility for the Bear Lodge REE Project. Pursuant to and subject to the terms of the Amendment, among other things, the term of the Repurchase Option (which was to expire on October 26, 2021) was extended for up to three additional years, subject to annual option

 (all amounts stated in thousands of U.S. dollars except share and per share amounts)

 extension payments from the Company to Whitelaw Creek of $ 25 in cash per year (each, a "Repurchase Option Extension Payment"); and the exercise price of the Repurchase Option was increased from $ 1,000 to a price to be determined by a mutually agreed upon real estate appraiser (the "Repurchase Price"), provided that (i) the Repurchase Price must not be less than $ 1,200 or greater than $ 1,850 and (ii) any Repurchase Option Extension Payments paid by the Company to Whitelaw Creek must be credited toward the Company's payment of the Repurchase Price if the Repurchase Option is later exercised. In October 2023, the Company made the $ 25 Repurchase Option Extension Payment to Whitelaw Creek to extend the term of the Repurchase Option through October 26, 2024.
 For accounting purposes, the Company has treated this transaction as a financing arrangement where the value of the land has been reflected in the Company's financial statements as an asset ("Investment in Land") with a related liability ("Repurchase Option") recorded for the Company's obligation under the Repurchase Option. Accretion expense is recorded each reporting period to increase the repurchase option liability to the maximum exercise price of $ 1,850, less any annual option payments of $ 25 per year. For the years ended December 31, 2023 and 2022, the Company recorded accretion expense of $ 283 and $ 284, respectively, related to this Repurchase Option.
 At December 31, 2023, the balance of the Repurchase Option has been classified as a current liability given the final Repurchase Option extension provided for in the Amendment ending on October 26, 2024.
 9. SHAREHOLDERS' EQUITY
 Stock-based Compensation
 As of December 31, 2023 and 2022, the Company had issued and outstanding stock options of 3,455,000 and 3,910,000, respectively, that were issued under its 10 % Rolling Stock Option Plan, as amended, and restated (the "2011 Plan") and 1,270,000 and 250,000, respectively, that were issued under its 2022 Equity Incentive Plan (the "2022 Plan").
 The 2011 Plan was replaced in 2022 by the 2022 Plan, and as such, no additional stock options can be granted under the 2011 Plan. Under the 2011 Plan, our Board of Directors could from time-to-time grant stock options to eligible directors, officers, employees, and consultants. The maximum term of any stock option grant under the 2011 Plan was 10 years.
 Under the 2022 Plan, as approved by our shareholders at the annual meeting of shareholders on August 23, 2022, our Board of Directors is authorized to grant stock options, stock appreciation rights, restricted stock units, performance stock units and other cash and share-based awards to eligible directors, officers, employees, or consultants up to a maximum of 17,236,689 common shares. The maximum term of any grant under the 2022 Plan is 10 years.
 The Company estimates the fair value of its stock option grants using the Black-Scholes option valuation model and the closing price of our common shares on the grant date. The significant assumptions used to estimate the fair value of the 1,020,000 and 2,080,000 stock option awards granted during the years ended December 31, 2023 and 2022, respectively, were as follows:

 Rights Offering
 On February 14, 2024, the Company launched a rights offering for gross proceeds of approximately $ 35,800 in which each holder of the Company's common shares as of the record date of December 15, 2023 would be eligible to participate. Terms of the rights offering include the issuance of one and four-tenth (or 1.4) subscription right for each common share owned by each holder on the record date with each subscription right entitling the holder to purchase one common share of the Company at a subscription price of $ 0.12 per share (the "basic subscription privilege"). For any holder exercising its basic subscription privilege in full, the holder could also exercise an oversubscription privilege to purchase additional common shares for which were unsubscribed at the expiration of the rights offering, subject to availability and pro rata

 (all amounts stated in thousands of U.S. dollars except share and per share amounts)

 allocation of shares among persons exercising the oversubscription privilege. The rights offering closed on March 11, 2024 and the gross proceeds of $ 35,800 were received.
 The net proceeds from this rights offering will be utilized to progress the Company's business strategy to support the advancement of the Bear Lodge REE Project, which includes funding the operation of the Demonstration Plant for a period of time that is expected to be sufficient to provide the information to support a commercialization decision, acquiring real property, updating the mineral resource model and technical reports, and advancing permitting, environmental support, and basic engineering, as well as for other general corporate purposes.
 10. INCOME TAX
 The Company recognizes future tax assets and liabilities for each tax jurisdiction based on the difference between the financial reporting and tax bases of assets and liabilities using the enacted tax rates expected to be in effect when the taxes are paid or recovered. A valuation allowance is provided against net future tax assets for which the Company does not consider the realization of such assets to meet the required "more likely than not" standard.
 The Company's future tax assets and liabilities at December 31, 2023 and 2022 include the following components:

 The valuation allowance increased by $ 2,010 from the year ended December 31, 2022 to the year ended December 31, 2023. Since it is more likely than not that the deferred tax assets will not be realized, the Company has recorded a full valuation allowance against the deferred tax assets.

 (all amounts stated in thousands of U.S. dollars except share and per share amounts)

 At December 31, 2023, the Company had U.S. federal net operating loss ("NOL") carryforwards of approximately $ 102,949 with expiration dates ranging from 2024 to those not having an expiration date and U.S. state NOL carryforwards of approximately $ 87,485 with expiration dates ranging from 2031 to 2043.
 As a result of the Tax Cuts and Jobs Act, U.S. federal NOL carryforwards generated in years ending after 2017 have an indefinite carryforward period (no expiration date) rather than the 20-year carryforward period that applied to those NOL carryforwards generated in 2017 and earlier years.
 Section 382 of the Internal Revenue Code could apply and limit our ability to utilize a portion of our U.S. federal NOL carryforwards. However, since no Section 382 study has been completed, the actual usage of U.S. federal NOL carryforwards has not been determined.
 At December 31, 2023, the Company also had Canadian non-capital loss carryforwards of approximately C$ 13,625, which expire from 2026 to 2043, and Canadian capital loss carryforwards of C$ 59 having no expiration dates.

 Rare Element files income tax returns in the Canadian federal and provincial jurisdictions, while its wholly owned subsidiary, Rare Element Resources, Inc., files U.S. federal and state tax returns. The years still open for audit are generally the current year plus the previous three. However, because we have NOL carryforwards, certain items attributable to closed tax years are still subject to adjustment by applicable taxing authorities through an adjustment to tax losses carried forward to open years.

 11. COMMITMENTS AND CONTINGENCIES
 Potential Environmental Contingency
 The Company's exploration and development activities are subject to various federal and state laws and regulations governing the protection of the environment. These laws and regulations are continually changing and generally have become more restrictive. The Company conducts its operations to protect public health and the environment and believes that its operations are materially in compliance with all applicable laws and regulations. The Company has made, and expects to make in the future, expenditures to comply with such laws and regulations. The ultimate amount of reclamation and other future site-restoration costs to be incurred for existing mining interests is uncertain.
 Contract Commitment – Related Party
 Pursuant to the Cost Share Agreement between the Company and General Atomics and as discussed more fully in Note 4, the Company has agreed to assume and pay for approximately one -half of the costs incurred by General Atomics and the other consortium members for the design, construction, operation, and decommissioning of the Demonstration Plant.

 Asset Purchase Agreement
 On October 25, 2021, the Company and Whitelaw Creek LLC, a Wyoming limited liability company ("Whitelaw Creek"), entered into an amendment (the "Amendment") to the asset purchase agreement dated October 20, 2016 between the Company and Whitelaw Creek (the "Asset Purchase Agreement"). The Amendment modified certain provisions of the Asset Purchase Agreement related to the terms and conditions of the Company's option to repurchase (the "Repurchase Option") approximately 640 acres of non-core real property located in Crook County, Wyoming, that is under consideration for a waste rock facility for the Bear Lodge REE Project. Pursuant to and subject to the terms of the Amendment, among other things, the term of the Repurchase Option (which was to expire on October 26, 2021) was extended for up to three additional years, subject to annual option extension payments from the Company to Whitelaw Creek of $ 25 in cash per year (each, a "Repurchase Option Extension Payment"); and the exercise price of the Repurchase Option was increased from $ 1,000 to a price to be determined by a mutually agreed upon real estate appraiser (the "Repurchase Price"), provided that (i) the Repurchase Price must not be less than $ 1,200 or greater than $ 1,850 and (ii) any Repurchase Option Extension Payments paid by the Company to Whitelaw Creek must be credited toward the Company's payment of the Repurchase Price if the Repurchase Option is later exercised. In October 2023, the Company made the $ 25 Repurchase Option Extension Payment to Whitelaw Creek to extend the term of the Repurchase Option through October 26, 2024.
 12. SUPPLEMENTAL DISCLOSURE WITH RESPECT TO CASH FLOWS
 The Company did not have any significant non-cash transactions during the years ended December 31, 2023 or 2022.
 13. SEGMENT INFORMATION
 The Company operates in a single reportable operating segment; that segment being the exploration of mineral properties. The Company's chief executive officer, who is the chief operating decision maker, reviews financial information on an aggregate basis for evaluating financial performance. All of the Company's long-lived assets are located in the United States.

Based on the evaluation, the principal executive officer and principal financial officer concluded that the disclosure controls and procedures in place are effective to ensure that information required to be disclosed by the Company in reports that the Company files or submits under the Exchange Act is recorded, processed, summarized, and reported within time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is accumulated and communicated to our management, including our principal executive and financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.
 Management's Report on Internal Control over Financial Reporting
 Our management is responsible for establishing and maintaining adequate internal control over financial reporting of the Company. Internal control over financial reporting is defined in Rule 13a-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executive and principal financial officers, and effected by our Board of Directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Our internal control over financial reporting includes those policies and procedures that:

 pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

 provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

 provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

 Because of their inherent limitations, internal controls over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
 Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2023. In making this assessment, our management used the criteria set forth in the Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on management's assessment, we have concluded that, as of December 31, 2023, our internal control over financial reporting was effective. Because we are a smaller reporting company and a non-accelerated filer, our independent registered public accounting firm is not required to attest to or issue a report on the effectiveness of our internal control over financial reporting.
 Changes in Internal Control over Financial Reporting
 There were no changes in our internal control over financial reporting during the quarter ended December 31, 2023 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

 ITEM 9B. OTHER INFORMATION
 Insider Trading Arrangements and Policies
 During the quarter ended December 31, 2023, none of our directors or executive officers adopted or terminated a "Rule 10b5-1 trading arrangement" or a "non-Rule 10b5-1 trading arrangement" (as those terms are defined in Item 408 of Regulation S-K).

 ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS; AND DIRECTOR INDEPENDENCE
 Transactions with Related Persons
 Cost Share Agreement with General Atomics
 On November 30, 2021, the Company and General Atomics, a California corporation and an affiliate of Synchron ("General Atomics"), entered into a Cost Share Funding Assumption Agreement (the "Cost Share Agreement") pursuant to which the Company agreed to assume and pay for certain costs incurred by General Atomics and the consortium for the design, construction, and operation of the Demonstration Plant near the Bear Lodge REE Project in Upton, Wyoming.
 As previously discussed, in January 2021, the DoE announced that a consortium of companies, which includes the Company, led by General Atomics, an affiliate of Synchron, and certain of its affiliates, and LNV, an Ardurra Group, Inc. company, as engineering and construction subcontractor, was selected for a potential financial award in the amount of $21.9 million for the engineering, construction and operation of the Demonstration Plant. The DoE award was finalized through a cooperative agreement dated October 1, 2021 (the "Cooperative Agreement") between General Atomics and the DoE with respect to the engineering, permitting, licensing, construction, and operation of the Demonstration Plant. The Cooperative Agreement provides that up to approximately $43.8 million in allowable costs for the Demonstration Plant will be funded on a cost-share basis, 50% by the DoE and 50% by a non-federal entity.
 Pursuant to the terms of the Cost Share Agreement, the Company is obligated to make payments totalling $21.9 million General Atomics, as leader of the consortium, for its share of the assumed costs for the Demonstration Plant, $15.7 million of which had been paid through December 31, 2023.
 The term of the Cost Share Agreement will continue until the date of completion of the Demonstration Plant, unless terminated earlier by either party. Either party may terminate the Cost Share Agreement immediately upon written notice to the other party if any of the following events occurs: (a) the Cooperative Agreement is terminated for any reason prior to the completion of the Demonstration Plant; (b) the other party commits a material breach of its obligations under the Cost Share Agreement and fails to cure such breach within 30 days; or (c) the other party makes an assignment for the benefit of its creditors, files a petition in bankruptcy, is adjudicated insolvent or bankrupt, or commences any insolvency or bankruptcy proceedings. Upon any early termination of the Cost Share Agreement, the Company must pay for all costs incurred by or on behalf of General Atomics to wind down the Demonstration Plant other than any allowable costs for such wind-down paid for by the DoE.
 Professional Services Agreement with Ms. Kast
 Ms. Kast is, and has been since June 2015, a consultant of Rare Element Resources, Inc., a subsidiary of the Company, and has served as a Board member since August 2022. From July 2012 to May 2015, Ms. Kast served as the Vice President, General Counsel, Chief Administrative Officer, and Corporate Secretary of the Company. On February 17, 2021, Rare Element Resources, Inc. entered into an updated professional services agreement, effective as of March 1, 2021, with Ms. Kast (the "Professional Services Agreement") that has since been extended on an annual basis and which currently runs through December 31, 2024. Pursuant to the Professional Services Agreement, Ms. Kast performs business consulting and administrative oversight services for Rare Element Resources, Inc., and the Company. The Professional Services Agreement provides that Ms. Kast shall be paid a monthly retainer and shall be eligible for an annual performance bonus at the discretion of the Board. For the fiscal years 2023 and 2022, Ms. Kast was paid monthly retainers of $20,208 and $19,250, respectively, and received cash bonuses of $82,500 and $75,000, respectively. Ms. Kast's monthly retainer was adjusted to $21,250 in 2024.
 Ms. Kast is also eligible for stock option grants pursuant to the Company's equity incentive plan and as approved by the Board. On January 4, 2023, and January 5, 2022, Ms. Kast received stock option grants of 225,000 and 500,000, respectively, that vested (i) 50% each on July 4, 2023, and January 4, 2024 for the 2023 grant, and (ii) 50% each on July 5, 2022, and January 5, 2023 for the 2022 grant.

 Legal and Consulting Arrangements with Mr. Hickey
 In June 2022, Mr. Hickey was retained as a consultant to Rare Element Resources, Inc., a subsidiary of the Company, and was paid a monthly retainer of $5,000 during fiscal years 2023 and 2022 for business and community relations services. Mr. Hickey had previously served as an advisor to affiliates of Synchron, the Company's majority shareholder, in several capacities, including serving as registered agent in the state of Wyoming for which he receives compensation of approximately $5,000 annually. Prior to his retirement as a partner of Hickey & Evans, LLP, he served as counsel to General Atomics (an affiliate of Synchron) and certain of its affiliates for various matters from 1980 through 2022. Mr. Hickey's monthly retainer was adjusted to $6,000 in 2024.
 Mr. Hickey is also eligible for stock option grants pursuant to the Company's equity incentive plan and as approved by the Board. On January 4, 2023, Mr. Hickey received a stock option grant of 50,000 that vested (i) 50% on July 4, 2023 and (ii) 50% on January 4, 2024.
 Review, Approval or Ratification of Transactions with Related Persons
 The Company's written corporate governance policies generally discourage transactions involving a potential conflict of interest. The NCG&C Committee is generally responsible for overseeing compliance with the Company's corporate governance policies, which require that transactions that could reasonably be considered to present a conflict of interest be reported to the NCG&C Committee. However, the Audit Committee is responsible for overseeing compliance with the Code of Conduct contained in the Company's corporate governance policies. Specifically, the Audit Committee is responsible for reviewing and overseeing any transaction or contract exceeding or likely to exceed $120,000 involving the Company and a related party, including transactions subject to disclosure under Item 404 of Regulation S-K. Generally, in reviewing such transactions, the Audit Committee considers the relevant facts and circumstances available and deemed relevant to each determination.
 Except for the Cost Share Agreement with General Atomics referenced above, there are no material interests, direct or indirect, of any of the current directors, executive officers, or any shareholder that beneficially owns, directly or indirectly, more than 5% of the outstanding Common Shares, or immediate family members of such persons, in any transaction since January 1, 2022 or in any proposed transaction in which the amount involved exceeded $120,000.
 Director Independence
 The Board reviewed and determined independence under National Instrument 58-101 – Disclosure of Corporate Governance Practices ("NI 58-101") of each current director. In making its independence determination, the Board considered the circumstances described below.
 Based upon the positions of Ms. Kast and Mr. Hickey as consultants to the Company and Mr. Berg as executive officer of the Company, the Board determined that they are not independent. The Board concluded that each of Ms. Champine and Messrs. Grandey, Brundage, and Roberts are independent. As a result of these analyses, the Board has determined that the seven-member Board is comprised of a majority of independent directors, as required under NI 58-101.
