Description of Business General uamy_10k.htm PART I Explanatory Note: As used in this report, the terms “we,” “us” and “our” are used to refer to United States Antimony Corporation and, as the context requires, its management. Some of the information in this Form 10-K contains forward-looking statements that involve substantial risks and uncertainties. You can identify these statements by forward-looking words as “may,” “will,” “expect,” “anticipate,” “believe,” “estimate” and “continue,” or similar words. You should read statements that contain these words carefully because they: discuss our future expectations; contain projections of our future results of operations or of our financial condition; and state other “forward-looking” information. ☐ ☐ ☐ History United States Antimony Corporation, or USAC, was incorporated in Montana in January 1970 to mine and produce antimony products. In December 1983, we suspended antimony mining operations but continued to produce antimony products from domestic and foreign sources. In April 1998, we formed United States Antimony SA de CV or USAMSA, to mine and smelt antimony in Mexico. Bear River Zeolite Company, or BRZ, was incorporated in 2000, and it is mining and producing zeolite in southeastern Idaho. On August 19, 2005, USAC formed Antimonio de Mexico, S. A. de C. V. to explore and develop antimony and silver deposits in Mexico. Our principal business is the production and sale of antimony, silver, gold, and zeolite products. On May 16, 2012, we started trading on the NYSE MKT (now NYSE AMERICAN) under the symbol UAMY. Antimony Division Our antimony smelter and precious metals plant is located in the Burns Mining District of Sanders County, Montana, approximately 15 miles west of Thompson Falls, MT. We hold 2 patented mill sites where the plant is located. We have no “proven reserves” or “probable reserves” of antimony, as these terms are defined by the Securities and Exchange Commission. Environmental restrictions preclude mining at this site. Mining was suspended in December 1983, because antimony could be purchased more economically from foreign sources. For 2021, and since 1983, we relied on foreign sources for raw materials, and there are risks of interruption in procurement from these sources and/or volatile changes in world market prices for these materials that are not controllable by us. We have sources of antimony in Mexico but we are still depending on foreign companies for raw material in the future. We expect to receive raw materials from our owned and leased properties for 2022 and later years. We continue working with suppliers in North America, Central America, and South America. We currently own 100% of the common stock, equipment, and the leases on real property of United States Antimony, Mexico S.A. de C.V. or “USAMSA”, which was formed in April 1998. We currently own 100% of the stock in Antimony de Mexico SA de CV (ADM) which owns the San Miguel concession of the Los Juarez property. USAMSA has two divisions, (1) the Madero smelter in Coahuila, (2) the Puerto Blanco flotation mill and oxide circuit in Guanajuato. ADM possesses the Los Juarez mineral deposit. 3 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 5/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm In our existing operations in Montana, we produce antimony oxide, antimony metal, and precious metals. Antimony oxide is a fine, white powder that is used primarily in conjunction with a halogen to form a synergistic flame-retardant system for plastics, rubber, fiberglass, textile goods, paints, coatings and paper. Antimony oxide is also used as a color fastener in paint, as a catalyst for production of polyester resins for fibers and film, as a catalyst for production of polyethylene pthalate in plastic bottles, as a phosphorescent agent in fluorescent light bulbs, and as an opacifier for porcelains. We also sell antimony metal for use in bearings, storage batteries and ordnance. We estimate (but have not independently confirmed) that our present share of the domestic market and international market for antimony oxide products is approximately 4% and less than 1%, respectively. We are the only significant U.S. producer of antimony products, while China supplies 92% of the world antimony demand. We believe we are competitive both domestically and world-wide due to the following: · · · · · · We have a reputation for quality products delivered on a timely basis. We have the only two operating, permitted, antimony smelters in North and Central America. We are the only domestic producer of antimony products. We can ship on short notice to domestic customers. We are vertically integrated, with raw materials from our own mines, mills, and smelter in Mexico, along with the raw materials from exclusive supply agreements we have with numerous ore and raw material suppliers. Our smelter in Coahuila is the largest operating antimony smelter in Mexico or the United States with a current maximum capacity of about 32,600 pounds of feed per day and permitting for 50% to 70% expansion. Following is a five-year schedule of our antimony sales: Year 2021 2020 2019 2018 2017 Lbs Metal Contained Sales ($) Average Price/Lb 911,079 $ 4,815,524 $ 815,310 2,942,628 1,566,585 5,450,649 1,486,120 6,113,014 1,891,439 7,588,470 5.29 3.61 3.48 4.11 4.01 Concentration of Sales: During the years ended December 31, 2021 and 2020, the following sales were made to our four largest customers: Sales to largest customers Company A Company B Company C Company D % of Total Revenues For the year ended December 31, 2021 1,728,406 1,141,608 850,301 518,227 $ 4,238,542 2020 $ 417,501 589,384 - 638,846 $ 1,645,731 55% 31% Marketing: We employ full-time marketing personnel and have negotiated various commission-based sales agreements with other chemical distribution companies. 4 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 6/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm Antimony Price Fluctuations: Our operating results have been, and will continue to be, related to the market prices of antimony metal, which have fluctuated widely in recent years. The volatility of prices is illustrated by the following table, which sets forth the average prices of antimony metal per pound, as reported by sources deemed reliable by us. A five-year range of prices for antimony oxide and antimony metal, per pound, was as follows: USAC SALES Year 2021 2020 2019 2018 2017 Metal Contained Price $ Rotterdam 4.91 2.45 3.03 3.74 3.78 5.29 $ 3.61 3.48 4.11 4.01 Antimony metal prices are determined by a number of variables over which we have no control. These include the availability and price of imported metals, the quantity of new metal supply, and industrial demand. If metal prices decline and remain depressed, our revenues and profitability may be adversely affected. We use various antimony raw materials to produce our products. We currently obtain antimony raw material from sources in Canada and Mexico. Zeolite Division We own 100% of Bear River Zeolite Company, (BRZ, an Idaho corporation) that was incorporated on June 1, 2000. BRZ has a lease with Webster Farm, L.L.C. that entitles BRZ to surface mine and process zeolite on property located near Preston, Idaho, in exchange for a royalty payment. In 2010 the royalty was adjusted to $10 per ton sold. The current minimum annual royalty is $60,000. In addition, BRZ has more zeolite on U.S. Bureau of Land Management land. The Company pays various royalties on the sale of zeolite products. William Raymond and Nancy Couse are paid a royalty that varies from $1 to $5 per ton. On a combined basis, royalties vary from 8%-13% of sales. Shortly after inception BRZ constructed a processing plant on the property which improved its productive capacity. Ground-breaking for an additional warehouse to store additional inventory and a shop to service equipment started in 2021 and the warehouse and shop are expected to be completed by mid-2022. A vertical-shaft-impactor crusher was replaced by a hammer mill for crushing line number 1 in 2021 for increased production rate. A replacement jaw crusher was installed and put into service in 2021. The new jaw crusher was further improved with a variable-speed apron feeder in late 2021 and subsequent and substantial improvements have been made to the jaw crusher in 2022. In 2021, the Company purchased a house in Preston Idaho for the express purpose of housing workers for its zeolite operation. We have no reserves nor resources of zeolite, as these terms are defined by the Securities and Exchange Commission. “Zeolite” refers to a group of industrial minerals that consist of hydrated aluminosilicates that hold cations such as calcium, sodium, ammonium, various heavy metals, and potassium in their crystal lattice. Water is loosely held in cavities in the lattice. BRZ zeolite is regarded as one of the best zeolites in the world due to its high CEC of approximately 180-220 meq/100 gr., its hardness and high clinoptilolite content, its absence of clay minerals, and its low sodium content. BRZ’s zeolite deposits’ characteristics which make the mineral useful for a variety of purposes including: ☐ Soil Amendment and Fertilizer. Zeolite has been successfully used to fertilize golf courses, sports fields, parks and common areas, and high value agricultural crops ☐ Water Filtration. Zeolite is used for particulate, heavy metal and ammonium removal in swimming pools, municipal water systems, fisheries, fish farms, and aquariums. ☐ Sewage Treatment. Zeolite is used in sewage treatment plants to remove nitrogen and as a carrier for microorganisms. 5 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 7/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm ☐ ☐ ☐ ☐ Nuclear Waste and Other Environmental Cleanup. Zeolite has shown a strong ability to selectively remove strontium, cesium, radium, uranium, and various other radioactive isotopes from solution. Zeolite can also be used for the cleanup of soluble metals such as mercury, chromium, copper, lead, zinc, arsenic, molybdenum, nickel, cobalt, antimony, calcium, silver and uranium. Odor Control. A major cause of odor around cattle, hog, and poultry feed lots is the generation of the ammonium in urea and manure. The ability of zeolite to absorb ammonium prevents the formation of ammonia gas, which disperses the odor. Gas Separation. Zeolite has been used for some time to separate gases, to re-oxygenate downstream water from sewage plants, smelters, pulp and paper plants, and fish ponds and tanks, and to remove carbon dioxide, sulfur dioxide and hydrogen sulfide from methane generators as organic waste, sanitary landfills, municipal sewage systems, animal waste treatment facilities, and is excellent in pressure swing apparatuses. Animal Nutrition. According to other research, feeding up to 2% zeolite increases growth rates, decreases conversion rates, and prevents scours. BRZ does not make these claims. ☐ Miscellaneous Uses. Other uses include catalysts, petroleum refining, concrete, solar energy and heat exchange, desiccants, pellet binding, horse and kitty litter, floor cleaner and carriers for insecticides, pesticides and herbicides. Environmental Matters Our exploration, development and production programs conducted in the United States are subject to local, state and federal regulations regarding environmental protection. Some of our production and mining activities are conducted on public lands. We believe that our current discharge of waste materials from our processing facilities is in material compliance with environmental regulations and health and safety standards. The U.S. Forest Service extensively regulates mining operations conducted in National Forests. Department of Interior regulations cover mining operations carried out on most other public lands. All operations by us involving the exploration for or the production of minerals are subject to existing laws and regulations relating to exploration procedures, safety precautions, employee health and safety, air quality standards, pollution of water sources, waste materials, odor, noise, dust and other environmental protection requirements adopted by federal, state and local governmental authorities. We may be required to prepare and present data to these regulatory authorities pertaining to the effect or impact that any proposed exploration for, or production of, minerals may have upon the environment. Any changes to our reclamation and remediation plans, which may be required due to changes in state or federal regulations, could have an adverse effect on our operations. The range of reasonably possible loss in excess of the amounts accrued, by site, cannot be reasonably estimated at this time. We accrue environmental liabilities when the occurrence of such liabilities is probable and the costs are reasonably estimable. The initial accruals for all our sites are based on comprehensive remediation plans approved by the various regulatory agencies in connection with permitting or bonding requirements. Our accruals are further based on presently enacted regulatory requirements and adjusted only when changes in requirements occur or when we revise our estimate of costs to comply with existing requirements. As remediation activity has physically commenced, we have been able to refine and revise our estimates of costs required to fulfill future environmental tasks based on contemporaneous cost information, operating experience, and changes in regulatory requirements. In instances where costs required to complete our remaining environmental obligations are clearly determined to be in excess of the existing accrual, we have adjusted the accrual accordingly. When regulatory agencies require additional tasks to be performed in connection with our environmental responsibilities, we evaluate the costs required to perform those tasks and adjust our accrual accordingly, as the information becomes available. In all cases, however, our accrual at year-end is based on the best information available at that time to develop estimates of environmental liabilities. Antimony Processing Site We have environmental remediation obligations at our antimony processing site near Thompson Falls, Montana (“the Stibnite Hill Mine Site”). We are under the regulatory jurisdiction of the U.S. Forest Service and subject to the operating permit requirements of the Montana Department of Environmental Quality. At December 31, 2021 and 2020, we have accrued $100,000 to fulfill our environmental responsibilities. 6 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 8/67 2/26/23, 4:29 PM Table of Contents BRZ uamy_10k.htm During 2001, we recorded a reclamation accrual for our BRZ subsidiary, based on an analysis performed by us and reviewed and approved by regulatory authorities for environmental bonding purposes. The accrual of $7,500 represents our estimated costs of reclaiming, in accordance with regulatory requirements, the acreage disturbed by our zeolite operations, and remains unchanged at December 31, 2021. General Reclamation activities at the Thompson Falls Antimony Plant were performed under supervision of the U.S. Forest Service and Montana Department of Environmental Quality. We have complied with regulators’ requirements and do not expect the imposition of substantial additional requirements. We have posted cash performance bonds with a bank and the U.S. Forest Service in connection with our reclamation activities. We believe we have accrued adequate reserves to fulfill our environmental remediation responsibilities as of December 31, 2021 and 2020. We have made significant reclamation and remediation progress on all our properties over thirty years and have complied with regulatory requirements in our environmental remediation efforts. Employees As of December 31, 2021, we employed 17 full-time employees in Montana. In addition, we employed 25 people at our zeolite plant in Idaho, and 27 employees at our mining, milling and smelting operation in Mexico. The number of full-time employees may vary seasonally. None of our employees are covered by any collective bargaining agreement. Other We hold no material patents, licenses, franchises or concessions. However, we consider our antimony processing plants proprietary in nature. We are subject to the requirements of the Federal Mining Safety and Health Act of 1977, the Occupational Safety and Health Administration’s regulations, requirements of the state of Montana and the state of Idaho, federal and state health and safety statutes and Sanders County, Montana and Franklin County, Idaho health ordinances. Item 1A Risk Factors There may be events in the future that we are not able to accurately predict or over which we have no control. The risk factors listed below, as well as any cautionary language in this report, provide examples of risks, uncertainties and events that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements. If we were liquidated, our common stockholders could lose part, or all, of their investment. In the event of our dissolution, the proceeds, if any, realized from the liquidation of our assets will be distributed to our stockholders only after the satisfaction of the claims of our creditors and preferred stockholders. The ability of a purchaser of shares to recover all, or any portion, of the purchase price for the shares, in that event, will depend on the amount of funds realized and the claims to be satisfied by those funds. We may have unasserted liabilities for environmental reclamation. Our research, development, manufacturing and production processes involve the controlled use of hazardous materials, and we are subject to various environmental and occupational safety laws and regulations governing the use, manufacture, storage, handling, and disposal of hazardous materials and some waste products. The risk of accidental contamination or injury from hazardous materials cannot be completely eliminated. In the event of an accident, we could be held liable for any damages that result and any liability could exceed our financial resources. We also have one ongoing environmental reclamation and remediation project at our current production facility in Montana. Adequate financial resources may not be available to ultimately finish the reclamation activities if changes in environmental laws and regulations occur, and these changes could adversely affect our cash flow and profitability. We do not have environmental liability insurance now, and we do not expect to be able to obtain insurance at a reasonable cost. If we incur liability for environmental damages while we are uninsured, it could have a harmful effect on our financial condition and results of operations.

We have accruals totaling $298,649 on our balance sheet at December 31, 2021, for our environmental reclamation responsibilities and estimated asset retirement obligations. If we are not able to adequately perform these activities on a timely basis, we could be subject to fines and penalties from regulatory agencies. Global health crises may adversely affect our planned operations. Our business could be materially and adversely affected by the risks, or the public perception of the risks, related to a pandemic or other health crisis, such as the recent outbreak of novel coronavirus (COVID-19). A significant outbreak of contagious diseases in the human population could result in a widespread health crisis that could adversely affect our planned operations. Such events could result in the complete or partial closure of our operations. In addition, it could impact economies and financial markets, resulting in an economic downturn that could impact our ability to raise capital. Item 1B Unresolved Staff Comments Not Applicable Item 2 Description of Properties ANTIMONY DIVISION Our antimony smelter and precious metals plant is located in the Burns Mining District, Sanders County, Montana, approximately 14 miles west of Thompson Falls on Montana Highway 471. This highway is asphalt, and the property is accessed by cars and trucks. The property includes two five-acre patented mill sites that are owned in fee-simple by us. The claims are U. S. Antimony Mill Site No. 1 (Mineral Survey 10953) and U. S. Antimony Mill Site No. 2 (Mineral Survey 10953). We also own five-acre Black Jack millsite. The U. S. Antimony Mill Sites were used to run a flotation mill and processing plant for antimony that we mined on adjacent claims that have been sold. Presently, we run a smelter that includes furnaces of a proprietary design to produce antimony metal, antimony oxide, and various other products. We also run a precious metals plant. The facility includes 6 buildings and our main office. There are no plans to resume mining on the claims that have been sold or abandoned, although the mineral rights have been retained on many of the patented mining claims. The U. S. Forest Service and Montana Department of Environmental Quality have told us that the resumption of mining would require an Environmental Impact Statement, massive cash bonding, and would be followed by years of lawsuits. The mill site is serviced with three-phase electricity from Northwest Power, and water is pumped from a well. We claim no reserves nor mineral resources on any of these properties. Antimony mining and milling operations in the U.S. were curtailed during 1983 due to continued declines in the price of antimony. We are currently purchasing foreign raw antimony materials and producing our own raw materials from our properties in Mexico. We continue to produce antimony metal, oxide, sodium antimonite, antimony trisulfide, and precious metals from our processing facility near Thompson Falls, Montana. ANTIMONY MINERAL PROPERTIES Los Juarez Group We hold properties that are collectively called the “Los Juarez” property, in Queretaro, as follows: 1. 2. 3. San Miguel I and II were purchased by a USAC subsidiary, Antimonio de Mexico, S. A. de C. V (ADM), for $1,480,500, which was paid in full as of December 31, 2018. As of December 31, 2020, we have paid for the property and have incurred significant permitting costs. The property consists of 40 hectares (100 acres) San Juan I and II are concessions owned by ADM and include 466 hectares (1,152 acres) San Juan III is held by a lease agreement by ADM in which we will pay a 10% royalty, based on the net smelter returns from another USAC Mexican subsidiary, named United States Antimony Mexico, S. A. de C. V. or USAMSA. It consists of 214 hectares (529 acres). https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 11/67 2/26/23, 4:29 PM uamy_10k.htm 8 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 12/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm The concessions collectively constitute 720 hectares (1,780 acres). The claims are accessed by roads that lead to highways. 9 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 13/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm Part of the USAC Mexican property, including San Miguel I, II and part of San Juan III, was originally drilled by the Penoles Company in 1970, when antimony metal prices were high. They did not proceed with the property, due to the complex metallurgy of antimony. Subsequently, the Mexican Government did additional work and reported a deposit of mineralized material of 1,000,000 metric tons (mt) grading 1.8% antimony and 8.1 ounces of silver per metric ton (opmt) in Consejo de Recursos Minerales (Publicacion M-4e). Such a report does not qualify as a comprehensive evaluation, such as a final or bankable feasibility study that concludes legal and technical viability, and economic feasibility. The Securities and Exchange Commission does not recognize this report, and we claim no reserves. The mineralized zone is a classic jasperoid-type deposit in the Cretaceous El Doctor Limestone. The mineralization is confined to silicified jasperoid pipes intruded upwards into limestone. The zone strikes north 70 degrees west. The dimension of the deposit is still conjectural. However, the strike length of the jasperoid is more than 3,500 meters. The mineralization is typically very fine-grained stibnite with silver and gold. It is primarily sulfide in nature due to its encapsulation in silica. The mining for many years will be by open pit methods. Eventually it will be by underground methods. At the present time, mining has included hauling dump rock and rock from mine faces. https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 14/67 2/26/23, 4:29 PM uamy_10k.htm In October 2020, a 1000 meter initial drill program was conducted on the property with a total of 25 holes. The drilling was completed November 2020 and used a reverse-circulation drill rig. Samples were sent to a certified lab in Mexico for analysis. Drill hole location, depth, and angle were selected near mined pit areas and along suspected fault zones. A summary of the drill program was published in a news release of November 30, 2020 and subsequent news releases. This initial program was performed without the aid of a geophysical study. In 2022, the Company is engaged in a formal geological, geochemical, and geophysical study to help obtain subsurface mineralization data and better understand the system with an objective of partnering with a junior mining company with expertise in exploration/drilling. 10 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 15/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm USAMSA Puerto Blanco Flotation Mill, Guanajuato, Mexico The flotation plant has a capacity of 100 metric tons per day. It includes a 30” x 42” jaw crusher, a 4’x 8’ double-deck screen, a 36” cone crusher, an 8’x 36” Harding type ball mill, and eight No. 24 Denver sub A type flotation machines, an 8’ disc filter, front end loaders, tools and other equipment. The flotation circuit is used for the processing of rock from Los Juarez and other properties. The crushing equipment currently in place is adequate for both flotation mills. An oxide circuit was added to the plant in 2013 and 2014 to mill oxide ores from Los Juarez and other properties. It includes a vertical shaft impactor, 3 ore bins, 8 conveyors, a 4’ x 6’ high frequency screen, jig, 8 standard concentrating tables, 5 pumps, sand screw and two buildings. The capacity of the oxide circuit is 50 tons per day. We have installed a cyanide leach circuit and settling pond that will be used to recover precious metals from our Los Juarez mine. In 2019 a cyanide leach circuit for recovery of gold was built and permits were obtained for this circuit. Test batches of Los Juarez antimony concentrates containing precious metals have been processed through the cyanide leach system and the processing of 2,000 tons of mined rock from Los Juarez is underway. One of three batches of gold-bearing carbon (the end product of the cyanide leach) have been saturated and awaits separation and analysis. Preliminary results are that the gold-recovery is acceptable. USAMSA Madero Smelter, Estacion Madero, Parras De La Fuente, Coahuila, Mexico USAC, through its wholly owned subsidiary, USAMSA, owns and operates a smelting facility at Estacion Madero, in the Municipio of Parras de la Fuente, Coahuila, Mexico. The property includes 13.48 hectares (30 acres). Seventeen small rotating furnaces (SRF’s) and four large rotating furnaces (LRF) with an associated stack and scrubbers. Other equipment includes cooling ducting, dust collectors, scrubber, laboratory, warehouse, slag vault, stack, jaw crusher, screen, hammer mill, and a 3.5’ x 8’ rod mill. The plant has a feed capacity of 14-25 metric tons of direct shipping ore per day, depending on the grade of the feedstock. If the feedstock is in the range of 45% antimony or higher, the smelter could produce as much as 10MM pounds of contained antimony annually. Concentrates from our flotation plant, and hand-sorted ore from Mexico sources and other areas, are being processed. In 2019, we completed the installation of a caustic leach circuit to process concentrates from the Puerto Blanco cyanide leach plant containing precious metals from our Los Juarez Mining property. The Madero production is either sold as metal to customers directly or crude oxide shipped to our Montana plant to produce finished antimony products and precious metals. Plans to dramatically improve and update the infrastructure at the Madero Smelter include erecting a building around all the furnaces to aid in the control, consistency, and quality of product and ease of processing. Additionally, the Company is considering producing finished antimony oxide with this control and purchasing quality- control instrumentation for the option of selling all finished antimony products from Madero just as we currently do in Montana. We intend to use part of our 2021 capital raise for the buildings, improving equipment, relining furnaces, purchase of newer forklifts, scales, and general improvement. Access to the plant is by road and railroad.

The mine is located in the N ½ of section 10 and the W ½ of section 2, section 3, and the E ½ section 4, Township 15, Range 40 East of the Boise Meridian, Franklin County, Idaho. The plant and the initial pit are located on the Webster Farm, L.L.C., which is private land. Transportation The property is accessed by seven miles of paved road and about l mile of gravel road from Preston, Idaho. Preston is near the major north-south Interstate Highway 15 to Salt Lake City or Pocatello. Several Union Pacific rail sidings may be available to the mine. Bonida is approximately 25 miles west of the mine and includes acreage out of town where bulk rock could be stored, possibly in existing silos or on the ground. Three-phase power is installed at this abandoned site. Finished goods can also be shipped from the Franklin County Grain Growers feed mill in the town of Preston on the Union Pacific Railroad. The Burlington Northern Railroad can be accessed at Logan, Utah. 12 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 17/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm Location Map Property and Ownership BRZ leases 320 acres from the Webster Farm, L.L.C. The term of the lease is 15 years and it began on March 1, 2010. This includes the mill site and zeolite in the area of the open pit. The property is the NW ¼ and W ½ of the SW ¼ of section 3 and the N ½ of the W ¼ of section 10, Township 15 South, Range 40 East of the Boise Meridian, Franklin County, Idaho. The lease requires a payment of $10.00 per ton plus an additional annual payment of $10,000 on March 1st of each year. In addition, there are two other royalty holders. Nick Raymond and the estate of George Desborough each have a graduated royalty of $1.00 per ton to $5.00 per ton, depending on the sale price. In early 2021, Joe Bardswhich, a director and geologist, was able to renegotiate one of the royalty payments so that escalation due to the CPI that existed in the original contract was removed. The balance of the property is on Bureau of Land Management property and includes 480 acres held by 24, 20-acre Placer claims. Should we drop our lease with Webster Farms LLC., we will retain these placer claims. Geology The deposit is a very thick, sedimentary deposit of zeolitized volcanic ash of Tertiary age known as the Salt Lake Formation. The sedimentary interval in which the clinoptilolite occurs is more than 1000 feet thick in the area. Thick intervals of the zeolite are separated by thin limestone and sandstone beds deposited in the freshwater lake where the volcanic ash accumulated. The deposit includes an 800- foot mountain. Zeolite can be sampled over a vertical extent of 800 feet on more than 700 acres. The current pit covers more than 3 acres. Despite the apparent size of the deposit, we claim no reserves. Exploration, Development, and Mining Exploration has been limited to the examination and sampling of surface outcrops and mine faces. Mining Methods Depending on the location, the zeolite is overlain by 1 to 12 feet of zeolite-rich soil. On the ridges, the cover is very little, and in the draws the soil is thicker. The overburden is stripped using a tractor dozer, currently a Caterpillar D-8K. It is moved to the toe of the pit, and will eventually be dozed back over the pit for reclamation. Although near-surface rock is easily ripped, it is more economical to drill and blast it. Breakage is generally good. Initial benches are 20 feet high, and each bench is accessed by a road. Haulage is over approximately 4,000 feet of road on an uphill grade of 2.5% to the mill. On higher benches, the grade will eventually be downhill. Caterpillar 769 B rock trucks are being used. They haul 18 to 20 tons per load, and the cycle time is about 30 minutes. https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 18/67 2/26/23, 4:29 PM uamy_10k.htm 13 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 19/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm In 2021, we experimented with the idea of mining principally by ripping using the Caterpillar D-9. This method worked but rendered rock that sometimes had to be drilled and broken in order to fit in the jaw crusher bin at the mill. Consequently, the Company is certain that blasting is the preferred method of mining. We may elect to supplement mining production by updating our D-9 with a secondary ripper. With the trucks and the other existing equipment, the mine is capable of producing 80 tons per hour. MILLING Primary Crusher The primary crushing circuit is a conventional closed circuit, utilizing a Stephens-Adamson 42” x 12’ apron feeder, Pioneer 30” x 42” jaw crusher, Nordberg standard 3’ cone crusher, a 5’ by 12’ double deck Kohlberg screen, and has a self-cleaning dust collector. The rock is crushed to minus 1 inch and the circuit has a rated capacity of more than 50 tons per hour. Dryer There are two dryer circuits, one for lines one and two, and one for the Raymond mill. The dryer circuits include one 50 ton feed bin, and each dryer has a conveyor bypass around each dryer, a bucket elevator, and a dry rock bin. The dryers are 25 feet long, 5 feet in diameter and are fired with propane burners rated at 750,000 BTUs. One self-cleaning bag house services both dryers. Depending on the wetness of the feed rock, the capacity is in the range of 10 tons per hour per dryer. During most of the year, the dryers are not run. Coarse Products Circuit In Oct/Nov 2021 the primary jaw crusher pitman arm broke due to incorrect greasing procedures. A replacement jaw crusher was purchased, delivered, installed and began operations 1.5 months after delivery. A delivery chute was designed and fabricated along with necessary bins and skirting. The new jaw crusher was outfitted with a hydraulic hand-pump greaser for the main pitman-arm assembly and the correct grease and greasing procedure has been implemented. Plans to fix or replace the old jaw crusher exist but require a major refit. The Company was able to repair the engine on its crane, a Linkbelt 3-stage boom crane of about 50 ton nameplate capacity. The transmission is now being repaired. With this crane, the Company will pull the old jaw crusher and determine if it is salvageable. In any case, the Company has earmarked that location for an entirely new and secondary jaw crusher in the event that bulk zeolite purchase opportunities increase. There are two lines to produce coarse products: · · Line 1 is a closed circuit with a 100 HP hammer mill (that replaced the old vertical shaft impactor) and a 5 deck Midwestern Multi Vibe high frequency screen. The replacement of the VSI with the hammermill, also outfitted with a variable frequency drive has increased production over the VSI by about 50% so far and we are continuing to test feeds and speeds to enhance this production rate. Line 2 includes a Jeffries 30” by 24” 60 HP hammer mill in a closed circuit with two 5’ x 12’ triple deck Midwestern Multi Vibe high frequency screens. The circuits also include bucket elevators, (3) 125-ton capacity product silos, a 6 ton capacity Crust Buster blender, augers, Sweco screens, and dust collectors. Fine Products Circuit The fine products circuit is in one building and it includes (2) 3.5’ x 10.5’ Derrick 2 deck high frequency (3450 RPM) screens and various bucket elevators, augers, bins, and Sweco screens for handling product. Depending on the screening sizes, the plants can generate approximately 150 tons of granules and 125 tons of fines per 24-hour day. Raymond Mill Circuit The Raymond mill circuit includes a 6058 high-side Raymond mill with a double whizzer, dust collector, two 100 ton product silos, feed bin, conveyors, air slide, bucket elevators, and control booth. The Raymond mill has a rated capacity of more than 10 tons per hour.

During the year ending December 31, 2021, the most significant factors affecting our financial performance were as follows: · · · · · · · · · Two private placements of stock during the first quarter of 2021. A significant, steady, and pronounced increase of the London Metals Bulletin price of antimony. The efforts in sales of zeolite of our zeolite sales director, Gretchen Lawrence. The addition of an antimony sales director, Mitzi Hart. The complete restructuring of office and plant personnel and procedures at the Montana and BRZ facilities. Increased trucking prices and decreasing trucking availability Difficulties in sourcing labor due to the Covid pandemic and the relief funding to curtail the incentive to work. The renegotiation of various supply, treatment, royalty, and tolling agreements. The retirement of several outstanding, old, and significant debts. During the year ended December 31, 2021, the most significant event affecting our financial performance was the addition of over $23 million to our working capital via two capital raises of common stock. These funds allowed the Company to retire much of its outstanding debt. It also allowed the Company leverage to re-negotiate existing contracts and pursue previously prohibitive ventures. The fact that the Company could pay its bills on time resulted in a serious amount of restructuring and the ability to offer more to attract and retain labor. Our plan for 2022 is as follows: · · · · · · · · · · · · · Continue processing tons of mined rock from the Los Juarez property at our Puerto Blanco facility. Continue to process ores and concentrates at our Madero facility. Finish the removal of all the legacy slag at Madero (should be completed early Q2 of 2022). Begin substantial improvements at the Madero facility including the initiation of the construction of a large set of buildings to house the furnaces, filter bags, and cooling towers in order for ability to produce finished antimony oxide. The purchase of new forklifts and scales at Madero facility. The relining of many of the small rotary furnaces at Madero facility. The installation of two new electric furnaces at the Montana facility for increase production of antimony trisulfide. The completion of the geological, geochemical, and geophysical study at the Los Juarez property (currently underway) in order to ascertain more information about the mineralization. This study is being done on an area approximately 3km in length by about 0.8 km in width to cover the entire region extending from the western limits of our mining concessions all the way to the ejido of Los Juarez. The continued effort to source antimony from Honduras and Nicaragua and other sources in Mexico and the United States. Continued talks with Perpetua Resources detailing a tolling or treatment charge agreement in keeping with our existing collaboration agreement. Finalization of several negotiations with land and concession owners in Mexico regarding additional sources of antimony. Continuation of the mining of the Soyatal claims with a particular experiment of the processing of 40 tons of hand-sorted sulfide rock for flotation in the hopes of an auxiliary source of concentrates for the production of antimony trisulfide. Continuation of the supply of sized antimony metal to Ambri in accordance with our letter of intent of 2020. The Company also intends to formalize its collaboration agreement with Perpetua Resources in the event that the demand of antimony from Ambri follows predicted trajectory. 16 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 23/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm In addition to the processing goals stated above, the Company intends to continue to improve its production capacity and sales of zeolite at its subsidiary Bear River Zeolite. These goals will be aided by the additional 100’ by 50’ warehouse for the storage and stockpile of product and also its 60’ x 40’ shop building, both of which should be completed in the first half of 2022. Also, the purchase of a Caterpillar 740 haul truck is underway to replace the defunct haul truck we had. The Company plans to purchase a replacement front-end loader for the mine to replace its 988-B Caterpillar that is on its last legs. The Company plans to then update the rippers on both Cat D-8 and D-9 supplement mining. A secondary, winter-storage platform located between the mine and the mill is planned. Salt sheds for these ore storage locations are planned to eliminate the necessity of the use of tarps for keeping the zeolite dry during the winter and rainy seasons. The following are highlights of the significant changes during 2021: Antimony: · · · · · Zeolite: The sale of antimony during 2021 was 911,079 lbs. compared to 815,310 pounds in 2020, an increase of 11.7%. The average sales price of antimony during 2021 was $5.29/lb. compared with $3.61/lb. in 2020, an increase of $1.68/lb. (a 46.5% increase). During the beginning of 2022, the Rotterdam price of antimony is approximately $6.06/lb. per pound. We are producing and buying raw materials, which will allow us to ensure a steady flow of products for sale. Our smelter at Madero, Mexico, was producing primarily ores from the Wadley mines in 2021. Our smelter in Montana was producing material from both Mexico and our North American sources in 2021. Raw materials from our North American supplier was reduced in 2021 due to the effects of Covid and shipping difficulties. We produced ingots of antimony metal in 2021 to be shipped directly to customers from our Madero smelter starting in 2022. We intend to increase this for 2022 and beyond. This will significantly reduce our production and shipping costs. We are proceeding with the processing of Los Juarez ore in the 100 ton per day mill at Puerto Blanco. Due to the hardness of the jasperoid rock at Los Juarez, it has been determined that the actual through-put is more like 80 tons per day. During 2021, the Company sold 11,747 tons compared to 10,661 tons in 2020, an increase of 1,086 tons (10.1%). Bear River Zeolite (“BRZ”) realized a gross profit of $340,806 (13.1% of sales) in 2021 compared to a gross profit of $323,780 (15.3% of sales) in 2020. Net income for the BRZ segment was $193,675 for the year ended December 31, 2021 compared to $262,861 for the year ended December 31, 2020. Corporate-wide: During the year ending December 31, 2021, the following transactions had a material impact on the Company’s net loss: · · On April 20, 2020, the Company received a loan of $443,400 pursuant to the Paycheck Protection Program (the “PPP”) under Division A, Title I of the CARES Act, which was enacted March 27, 2020. During the year ended December 31, 2021, the Company received notification that the loan had been forgiven. The amount of the loan, $443,400, was recognized as gain on forgiveness of the CARES Act loan. On November 7, 2014, the Company entered into an advance and concentrate processing agreement with Hillgrove Mines Pty Ltd of Australia (Hillgrove) in which the Company was advanced funds from Hillgrove to build facilities to process Hillgrove antimony concentrate. The Company has not processed Hillgrove concentrate for more than two years. The balance of the advance liability due was $1,134,221 at December 31, 2020. In April 2021, the Company successfully negotiated a settlement with Red River for an agreed upon amount of $1,020,799 which was paid on paid on April 8, 2021. The Company recognized a gain on settlement of the advance in the amount of $113,422 during the year ended December 31, 2021 (Note 8) 17 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 24/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm · · · Starting in August of 2021, US Antimony negotiated with our Canadian feed source for a more favorable treatment charge contract to replace the previous one. This contract became effective in December of 2021 and represents an improvement from the previous treatment charge contract. Throughout 2021, the price of antimony increased steadily. Throughout 2021, the price of trucking, lumber (for pallets), fuel, and labor increased. The Company raised its starting wages twice at the facility in Montana and once at Bear River Zeolite. Operational and financial performance Antimony Sales Our sales volume of antimony for the year ended December 31, 2021 was as follows: Antimony - Combined USA and Mexico Total Revenue - Antimony Total Lbs of Antimony Metal Sold Average Sales Price/Lb Metal Average cost per Lb Metal Average gross profit per Lb Metal 2021 2020 $ $ 4,815,524 $ 2,942,628 815,310 3.61 3.86 (0.25) 911,079 5.29 $ 4.99 0.30 $ $ During 2021, we saw our average sale price for antimony increase by $1.68/lb from an average of $3.61/lb in 2020 to $5.29/lb in 2021. In the 4th quarter 2021, the Company renegotiated a treatment-charge contract with its North American supplier of sodium antimonate. This contract renegotiation became effective in December 2021 and will result in a more favorable price of purchased antimony contained that had previously existed. During 2020, we saw our average sale price increase by $0.13 per pound from an average of $3.48 per pound for 2019 to an average of $3.61 per pound for 2020. Following the change in management in June and the suppressed price of antimony, the Company temporarily suspended sale of antimony oxide. This decision was made principally in order to minimize the loss per pound in sales at a time for which our production acquisition contracts were being renegotiated. As consequence of these decisions, the Company was, as of the first quarter of 2021, obtaining its raw materials from its Mexican sources at a substantial savings as compared to the previous year. These savings were due to the withdrawal of overhead from the staff it had at the Wadley mine. Additionally, the Company is now processing antimony products at its Madero facility at a substantial savings compared with all previous years. These savings were due to the renegotiating of its natural gas contract for the Madero smelter which was completed in early 2021. Furthermore, the Company has been able to produce finished antimony ingots and will sell them directly from its Madero facility starting in 2022. This saves at least $0.29/lb in shipping to and the finishing costs at Montana. 18 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 25/67 2/26/23, 4:29 PM Table of Contents Zeolite Sales uamy_10k.htm Our sales volume of zeolite for the year ended December 31, 2021 was as follows: Zeolite Total Revenue - Zeolite Tons of zeolite sold Average Sales Price/Ton Average cost per ton Average gross profit per ton 2021 2020 $ $ 2,593,641 $ 2,118,823 10,661 198.75 168.37 30.37 11,747 220.78 $ 191.77 29.01 $ $ Our sales volume of zeolite in 2021 was 1,086 tons more than we sold in 2020, an increase of 10%.

Current assets increased due to an increase in cash and cash equivalents. Our current liabilities decreased by $2,456,690 which included a decrease of approximately $662,140 in accounts payables and payables to related parties, a decrease of $1,120,730 due to Mexican export tax liability. Capital improvements were paid for with cash. For the year ending December 31, 2022, we are planning to use funds acquired from the two stock offerings raised in 2021 to make significant improvements to our operations at Madero, Puerto Blanco, Bear River Zeolite, and Thompson Falls facilities with the goal of increasing production and decreasing costs. Critical Accounting Estimates We have, besides our estimates of the amount of depreciation on our assets, two critical accounting estimates. The percentage of antimony contained in our unprocessed ore in inventory is based on assays taken at the time the ore is delivered, and may vary when the ore is processed. Also, the asset recovery obligation on our balance sheet is based on an estimate of the future cost to recover and remediate our properties as required by our permits upon cessation of our operations, and may differ when we cease operations. · · The value of unprocessed ore is based on assays taken at the time the ore is delivered, and may vary when the ore is processed. We assay the ore to estimate the amount of antimony contained per metric ton, and then make a payment based on the Rotterdam price of antimony and the % of antimony contained. Our payment scale incorporates a penalty for ore with a low percentage of antimony. It is reasonably likely that the initial assay will differ from the amount of metal recovered from a given lot. If the initial assay of a lot of ore on hand at the end of a reporting period were different, it would cause a change in our reported inventory, but would not change our accounts payable, reported cost of goods sold or net income amounts. Our net income would not be affected. Direct shipping ore (DSO) purchased at our Madero smelter is paid for at a fixed amount at the time of delivery and assaying, and is not subject to accounting estimates. The amount of the accounting estimate for purchased ore at our Puerto Blanco mill is in a constant state of change because the amount of purchased ore and the per cent of metal contained are constantly changing. Due to the amount of ore on hand at the end of a reporting period, as compared to the amount of total assets, liabilities, equity, and the ore processed during a reporting period, any change in the amount of estimated metal contained would likely not result in a material change to our financial condition. The asset retirement obligation and asset on our balance sheet is based on an estimate of the future cost to recover and remediate our properties as required by our permits upon cessation of our operations, and may differ when we cease operations. We make periodic reviews of the remaining life of the mine and other operations, and the estimated remediation costs upon closure, and adjust our account balances accordingly. At this time, we think that an adjustment in our asset recovery obligation is not required, and an adjustment in future periods would not have a material impact in the year of adjustment, but would change the amount of the annual accretion and amortization costs charged to our expenses by an undetermined amount. 21 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 28/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm Item 7A Quantitative and Qualitative Disclosures about Market Risk Not Applicable. Item 8 Financial Statements The consolidated financial statements of the registrant are included herein on pages F1-F22. Item 9 Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None Item 9A Controls and Procedures Evaluation of disclosure controls and procedures At the end of the period covered by this Annual Report on Form 10-K, an evaluation was carried out under the supervision of and with the participation of our management, including the Principal Executive Officer and the Principal Financial Officer of the effectiveness of the design and operations of our disclosure controls and procedures (as defined in Rule 13a – 15(e) and Rule 15d – 15(e) under the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, the Principal Executive Officer and the Principal Financial Officer have concluded that our disclosure controls and procedures were not effective in ensuring that: (i) information required to be disclosed by the Company in reports that it files or submits to the Securities and Exchange Commission under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in applicable rules and forms and (ii) material information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow for accurate and timely decisions regarding required disclosure. Disclosure controls and procedures were not effective due primarily to material weaknesses in the Company’s internal control of financial reporting as discussed below. Internal control over financial reporting Management’s annual report on internal control over financial reporting The management of USAC is responsible for establishing and maintaining adequate internal control over financial reporting. This internal control system has been designed to provide reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of our published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. The management of USAC has assessed the effectiveness of our internal control over financial reporting as of December 31, 2020. To make this assessment, we used the criteria for effective internal control over financial reporting described in Internal Control-Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). As a result of our assessment, we concluded that we have material weaknesses in our internal control over financial reporting as of December 31, 2021. These weaknesses are as follows: · · · Inadequate design of internal control over the preparation of the financial statements and financial reporting processes; Inadequate monitoring of internal controls over significant accounts and processes including controls associated with domestic and Mexican subsidiary operations and the period-end financial reporting process; and The absence of proper segregation of duties within significant processes and ineffective controls over management oversight, including antifraud programs and controls. We are aware of these material weaknesses and will develop procedures to ensure that independent review of material transactions is performed. The chief financial officer will develop internal control measures to mitigate the inadequate documentation of controls and the monitoring of internal controls over significant accounts and processes including controls associated with the period-ending https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 29/67 2/26/23, 4:29 PM uamy_10k.htm reporting processes, and to mitigate the segregation of duties within significant accounts and processes and the absence of controls over management oversight, including antifraud programs and controls. We plan to consult with independent experts when complex transactions are entered into. Because these material weaknesses exist, management has concluded that our internal control over financial reporting as of December 31, 2021, is ineffective. Changes in internal control over financial reporting There were no changes in internal control over financial reporting for the quarter ended December 31, 2021. 22 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 30/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm PART III Item 10 Directors, Executive Officers, Promoters and Control Persons, Compliance with Section 16(a) of the Exchange Act Identification of directors and executive officers at December 31, 2021, is as follows: Name Age Affiliation Expiration of Term John C.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the years then ended, 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 Matter Evaluation of properties, plants, and equipment for impairment triggering events As discussed in Note 2 to the consolidated financial statements, the Company evaluates properties, plants, and equipment (“PPE”) to identify events or changes in circumstances, referred to as triggering events, that indicate the carrying value of PPE may not be recoverable. An impairment loss is recorded in the period in which it is determined that the carrying amount of PPE is not recoverable. As of December 31, 2021, the carrying value of properties, plants and equipment, net was approximately $11.1 million. We identified the evaluation of PPE for impairment triggering events as a critical audit matter. A high degree of subjective auditor judgment was required in evaluating the Company’s assessment of current operations, financial results and historical projections, current industry and market conditions, and relevant industry data for impairment indicators. The following are the primary procedures we performed to address this critical audit matter. · We evaluated the Company’s process of identifying and assessing potential triggering events, including the Company’s assessment of current operations, financial results and historical projections, current industry and market conditions, and relevant industry data. https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 43/67 2/26/23, 4:29 PM uamy_10k.htm · We evaluated the Company’s identification and assessment of triggering events by evaluating current period operations, financial results and historical projections, including current industry and market considerations. We compared relevant industry data used by the Company to external sources, including market index data. · We evaluated the Company’s analysis over the factors and considered whether the Company omitted any significant internal or external elements in its evaluation. /s/ Assure CPA, LLC Spokane, Washington March 31, 2022 We have served as the Company’s independent auditor since 1998.

Background of Company and Basis of Presentation AGAU Mines, Inc., predecessor of United States Antimony Corporation (“USAC” or “the Company”), was incorporated in June 1968 as a Delaware corporation to mine gold and silver. USAC was incorporated in Montana in January 1970 to mine and produce antimony products. In June 1973, AGAU Mines, Inc. was merged into USAC. In December 1983, the Company suspended its antimony mining operations when it became possible to purchase antimony raw materials more economically from foreign sources. The principal business of the Company has been the production and sale of antimony products. During 2000, the Company formed a 75% owned subsidiary, Bear River Zeolite Company (“BRZ”), to mine and market zeolite and zeolite products from a mineral deposit in southeastern Idaho. In 2001, an operating plant was constructed at the zeolite site and zeolite production and sales commenced. During 2002, the Company acquired the remaining 25% of BRZ and continued to produce and sell zeolite products. During 2005, the Company formed a 100% owned subsidiary, Antimonio de Mexico S.A. de C.V. (“AM”), to explore and develop potential antimony properties in Mexico. During 2006, the Company acquired 100% ownership in United States Antimony, Mexico S.A. de C.V. (“USAMSA”), which became a wholly-owned subsidiary of the Company. In 2018, the Company acquired 100% ownership in Stibnite Holding Company US Inc. (previously Lanxess Holding Company US Inc.), Antimony Mining and Milling US LLC (previously Lanxess Laurel US LLC), a Delaware limited liability company and Lanxess Laurel de Mexico, S.A. de C.V (“Lanxess Laurel Mexico”), a Mexico corporation, both of which became a wholly- owned subsidiary of the Company. COVID-19 Coronavirus Pandemic Response and Impact Following the outbreak of the COVID-19 coronavirus global pandemic (“COVID-19”) in early 2020, in March 2020 the U.S. Centers for Disease Control issued guidelines to mitigate the spread and health consequences of COVID-19. The Company implemented changes to its operations and business practices to follow the guidelines and minimize physical interaction, including using technology to allow employees to work from home when possible and altering production procedures and schedules, asset maintenance, and limiting discretionary spending. We continue to monitor guidance from federal, state, local and foreign governments and public health authorities and may need to take additional actions based on their recommendations. The extent of the impact of COVID-19 on our business and financial results will also depend on future developments, including the duration and spread of the outbreak and the success of the current vaccination programs, all of which are uncertain. 2. Summary of Significant Accounting Policies Principles of Consolidation The Company’s consolidated financial statements include the accounts of its wholly-owned subsidiaries BRZ, USAMSA, AM, Stibnite Holding Company US Inc., and Antimony Mining and Milling US LLC. All intercompany balances and transactions are eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 revenues and expenses during the reporting period. Significant and critical estimates include property, plant and equipment depreciation and potential impairment, metal content of mineral resources, accounts receivable allowance for uncollectible accounts, net realizable value of inventories, deferred income taxes, income taxes payable, environmental remediation liabilities and asset retirement obligations. Actual results could differ from those estimates. https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 49/67 F-6 2/26/23, 4:29 PM Table of Contents uamy_10k.htm United States Antimony Corporation and Subsidiaries Notes to Consolidated Financial Statements December 31, 2021 and 2020 Cash and Cash Equivalents The Company considers cash in banks and investments with original maturities of three months or less when purchased to be cash equivalents. At December 31, 2021 and 2020, restricted cash for reclamation bonds of $57,281 and $57,275 are included in cash and cash equivalents and restricted cash balances on the statements of cash flows Restricted Cash Restricted cash at December 31, 2021 and 2020 consists of cash held for reclamation performance bonds and is held in certificates of deposit with financial institutions. Accounts Receivable Accounts receivable are stated at the amount that management expects to collect from outstanding balances. Management provides for probable uncollectible amounts through an allowance for doubtful accounts. Changes to the allowance for doubtful accounts are based on management’s judgment, considering historical write-offs, collections and current credit conditions. Balances which remain outstanding after management has used reasonable collection efforts are written off through a charge to the allowance for doubtful accounts and a credit to the applicable accounts receivable. Payments received on receivables subsequent to being written off are considered a bad debt recovery. Inventories Inventories at December 31, 2021 and 2020 consisted of finished antimony products, antimony metal, antimony concentrates, antimony ore, and finished zeolite products, and are stated at the lower of first-in, first-out weighted average cost or estimated net realizable value. Finished antimony products, antimony metal and finished zeolite products costs include raw materials, direct labor and processing facility overhead costs and freight allocated based on production quantity. Stockpiled ore is carried at the lower of average cost or net realizable value. Since the Company’s antimony inventory is a commodity with a sales value that is subject to world prices for antimony that are beyond the Company’s control, a significant change in the world market price of antimony could have a significant effect on the net realizable value of inventories. The Company periodically reviews its inventories to identify excess and obsolete inventories and to estimate reserves for obsolete inventories as necessary to reflect inventories at net realizable value. Translations of Foreign Currencies All amounts in the financial statements are presented in U.S. dollars, which is the functional currency for all of the Company’s operations. Foreign translation gains and losses relating to Mexican subsidiaries are recognized as foreign exchange gain or loss in the consolidated statement of operations. Properties, Plants and Equipment Properties, plants and equipment are stated at historical cost and are depreciated using the straight-line method over estimated useful lives of two to thirty years. Vehicles and office equipment are stated at cost and are depreciated using the straight-line method over estimated useful lives of three to twelve years. Maintenance and repairs are charged to operations as incurred. Betterments of a major nature are capitalized. Expenditures for new property, plant, equipment, and improvements that extend the useful life or functionality of the asset are capitalized. When assets are retired or sold, the costs and related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in operations. The costs to obtain the legal right to explore, extract and retain at least a portion of the benefits from mineral deposits are capitalized as mineral rights in the year of acquisition. These capitalized costs are amortized on the statement of operations using the straight-line method over the expected life of the mineral deposit when placed into production. Mineral rights are assessed for impairment when facts and circumstances indicate that the potential for impairment exists. Mineral rights are subject to write down in the period the property is abandoned. Mineral properties are amortized over the estimated economic life of the mineral resource using the straight-line method, based upon estimated lives of the properties, or the units-of-production method, based upon estimated units of mineral resource. https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 50/67 2/26/23, 4:29 PM uamy_10k.htm F-7 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 51/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm United States Antimony Corporation and Subsidiaries Notes to Consolidated Financial Statements December 31, 2021 and 2020 Impairment of Long-lived Assets Management reviews and evaluates the net carrying value of its long-lived assets for impairment upon the occurrence of events or changes in circumstances that indicate that the related carrying amounts may not be recoverable. A test for recoverability is performed based on the estimated undiscounted future cash flows that will be generated from operations at each property and the estimated salvage value of asset. Although management has made what it believes to be a reasonable estimate of factors based on current conditions and information, assumptions underlying future cash flows, which includes the estimated value of assets, are subject to significant risks and uncertainties. Estimates of undiscounted future cash flows are dependent upon, among other factors, estimates of: (i) product and metals to be recovered from identified mineralization and other resources (ii) future production and capital costs, (iii) estimated selling prices (considering current, historical, and future prices) over the estimated remaining life of the asset and (iv) market values of property, if appropriate. It is possible that changes could occur in the near term that could adversely affect the estimate of future cash flows to be generated from operating properties. If estimated undiscounted cash flows are less than the carrying value of an asset, an impairment loss is recognized for the difference between the carrying value and fair value of the asset. Exploration and Development The Company expenses exploration costs as such in the period they occur. The mine development stage begins once the Company has determined an ore body can be economically developed. Expenditures incurred during the development stage are capitalized as deferred development costs. Costs to improve, alter, or rehabilitate primary development assets which appreciably extend the life, increase capacity, or improve the efficiency or safety of such assets are also capitalized. The development stage ends when the production stage of reserves begins. Deferred development costs are amortized over the estimated economic life of the mineral resource using the straight-line method, based upon estimated lives of the properties, or the units-of-production method, based upon estimated units of mineral resource. Asset Retirement Obligations and Reclamation Costs All of the Company’s mining operations are subject to reclamation and remediation requirements. Minimum standards for mine reclamation have been established by various governmental agencies. Costs are estimated based primarily upon environmental and regulatory requirements and are accrued. The liability for reclamation is classified as current or noncurrent based on the expected timing of expenditures. Reclamation differs from an asset retirement obligation in that no associated asset is recorded in the case of reclamation liabilities. It is reasonably possible that because of uncertainties associated with defining the nature and extent of environmental contamination, application of laws and regulations by regulatory authorities, and changes in remediation technology, the ultimate cost of remediation and reclamation could change in the future. The Company continually reviews its accrued liabilities for such remediation and reclamation costs as evidence becomes available indicating that its remediation and reclamation liability has changed. The Company records the fair value of an asset retirement obligation as a liability in the period in which the Company incurs a legal obligation for the retirement of long-lived assets if it is probable that such costs will be incurred and they are reasonably estimable. A corresponding asset is also recorded and depreciated over the life of the assets on a straight-line basis. After the initial measurement of the asset retirement obligation, the liability will be adjusted to reflect changes in the estimated future cash flows underlying the obligation. Determination of any amounts included in determination of fair value is based upon numerous estimates and assumptions, including future retirement costs, future inflation rates, and the Company’s credit-adjusted risk-free interest rates.

The Company has determined the performance obligation is met and title is transferred either upon shipment from the Company’s warehouse locations or upon receipt by the customer as specified in individual sales orders. The performance obligation is met because at that time, 1) legal title is transferred to the customer, 2) the customer has accepted the product and obtained the ability to realize all of the benefits from the product, 3) the customer has the significant risks and rewards of ownership to it, 4) it is very unlikely product will be rejected by the customer upon physical receipt, and 5) the Company has the right to payment for the product. Shipping costs related to the sales of antimony and zeolite products are recorded to cost of sales as incurred. For zeolite products, royalty expense due a third party by the Company is also recorded to cost of sales upon sale in accordance with terms of underlying royalty agreements. For sales of precious metals, the performance obligation is met, the transaction price is known, and revenue is recognized at the time of transfer of control of the agreed-upon metal quantities to the customer. Refining and shipping costs related to sales of precious metals are recorded to cost of sales as incurred. The Company has determined that its contracts do not include a significant financing component. Prepayments, which are not common, received from customers prior to the time that products are processed and shipped, are recorded as deferred revenue. For antimony and zeolite sales contracts, the Company may factor certain receivables and receive final payment within 30 days of the performance obligation being met. For antimony and zeolite receivables not factored, the Company typically receives payment within 10 days. For precious metals sales, a provisional payment of 75% is typically received within 45 days of the date the product is delivered to the customer. After an exchange of assays, a final payment is normally received within 90 days of product delivery. Common Stock Issued for Consideration Other than Cash All transactions in which goods or services are received for the issuance of shares of the Company’s common stock are accounted for based on the fair value of the common stock issued. Income Taxes Income taxes are accounted for under the liability method. Under this method, deferred income tax liabilities or assets are determined at the end of each period using the tax rate expected to be in effect when the taxes are actually paid or recovered. A valuation allowance is recognized on deferred tax assets when it is more likely than not that some or all of these deferred tax assets will not be realized. The Company applies generally accepted accounting principles for recognition of uncertainty in income taxes and prescribing a recognition threshold and measurement attribute for the recognition and measurement of a tax position taken or expected to be taken in a tax return.

Diluted earnings per share is calculated based on the weighted average number of common shares outstanding during the period plus the effect of potentially dilutive common stock equivalents, including stock options, warrants to purchase the Company’s common stock, and convertible preferred stock. For the years ended December 31, 2020 and 2020, potentially dilutive common stock equivalents not included in the calculation of diluted earnings per share because they were anti-dilutive are as follows: Warrants Convertible preferred stock Total possible dilution Fair Value of Financial Instruments December 31, 2021 December 31, 2020 12,489,922 6,194,899 1,692,672 1,751,005 14,182,594 7,945,904 The Company’s financial instruments include cash and cash equivalents, certificates of deposits, and restricted cash. The carrying value of these instruments approximates fair value based on their contractual terms. Fair Value Measurements When required to measure assets or liabilities at fair value, the Company uses a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used. The Company determines the level within the fair value hierarchy in which the fair value measurements in their entirety fall. The categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Level 1uses quoted prices in active markets for identical assets or liabilities, Level 2 uses significant other observable inputs, and Level 3 uses significant unobservable inputs. The amount of the total gains or losses for the period are included in earnings that are attributable to the change in unrealized gains or losses relating to those assets and liabilities still held at the reporting date.The Company has no financial assets or liabilities that are adjusted to fair value on a recurring basis. Contingencies In determining accruals and disclosures with respect to loss contingencies, the Company evaluates such accruals and contingencies for each reporting period. Estimated losses from loss contingencies are accrued by a charge to income when information available prior to issuance of the financial statements indicates that it is probable that a liability could be incurred and the amount of the loss can be reasonably estimated. Legal expenses associated with the contingency are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the financial statements when it is at least reasonably possible that a material loss could be incurred. Recent Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12 Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The update contains a number of provisions intended to simplify the accounting for income taxes. The update was adopted as of January 1, 2021, and its adoption did not have a material impact on the Company’s consolidated financial statements. Accounting standards that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have a material impact on the financial statements upon adoption.

At December 31, 2019, warrants for purchase of 250,000 shares of the Company’s common stock for $0.25 per share were outstanding. These warrants were owned by the Company’s previous President and Chairman, John Lawrence. The warrants were exercised on March 18, 2020 in exchange for a reduction in an amount payable to Mr. Lawrence. In July 2020, warrants for purchase of 5,742,858 shares of the Company’s common stock were sold with shares of common stock. The warrants have an exercise price of $0.46 per share and expire in 2025. The warrants can be exercised on a cashless basis. The warrants contain a repricing provision whereby if the Company raises at least $6,000,000 in gross proceeds from the sale of its common stock at an effective price per share less than the warrants’ exercise price, the exercise price of the warrants will be repriced to the lower price. In February 2021, concurrent with sale of common stock, the Company issued warrants to purchase 7,650,000 shares of common stock at an exercise price of $0.85 per share. The warrants are initially exercisable six months following issuance and expire five and one-half years from the issuance date. In connection with the February 2021 sales of common stock, the Company also issued 1,606,500 warrants with an exercise price of $0.85 and 804,000 warrants with an exercise price of $0.46 as commission to the placement agent.

Series B During 1993, the Board established a Series B preferred stock, consisting of 750,000 shares. The Series B preferred stock has preference over the Company’s common stock and Series A preferred stock (none of which are outstanding); has no voting rights (absent default in payment of declared dividends); and is entitled to cumulative dividends of $0.01 per share per year, payable if and when declared by the Board of Directors. During each of the years ended December 31, 2021 and 2020 the Company recognized $7,500 in Series B preferred stock dividend. In the event of dissolution or liquidation of the Company, the preferential amount payable to Series B preferred stockholders is $1.00 per share plus dividends in arrears. No dividends have been declared or paid with respect to the Series B preferred stock. The Series B Preferred stock is no longer convertible to shares of the Company’s common stock. At December 31, 2021 and 2020, cumulative dividends in arrears on the outstanding Series B shares were $202,500 and $195,000, respectively. Series C During 2000, the Board established a Series C preferred stock. The Series C preferred stock has preference over the Company’s common stock and has voting rights equal to that number of shares outstanding, but no conversion or dividend rights. In the event of dissolution or liquidation of the Company, the preferential amount payable to Series C preferred stockholders is $0.55 per share. Series D During 2002, the Board established a Series D preferred stock, authorizing the issuance of up to 2,500,000 shares. The Series D preferred stock has preference over the Company’s common stock but is subordinate to the liquidation preferences of the holders of the Company’s outstanding Series A, Series B and Series C preferred stock. Series D preferred stock carries voting rights and is entitled to annual dividends of $0.0235 per share. The dividends are cumulative and payable after payment and satisfaction of the Series A, B and C preferred stock dividends. No dividends have been declared or paid with respect to the Series D preferred stock. During the year ended December 31, 2021, 58,333 shares of Series D preferred stock was converted to 58,333 shares of the Company’s common stock. As part of this conversion, the shareholder was issued 64,184 shares of the Company’s common stock to satisfy cumulative dividends associated with the preferred shares. At December 31, 2021 and 2020, the cumulative dividends in arrears on the outstanding Series D shares were $747,952 and $707,258, respectively, payable if and when declared by the Board of Directors. In the event of dissolution or liquidation of the Company, the preferential amount payable to Series D preferred stockholders is $2.50 per share. At December 31, 2021 and 2020, the liquidation preference for Series D preferred stock was $4,979,632 and $5,084,770, respectively. Holders of the Series D preferred stock have the right, subject to the availability of authorized but unissued common stock, to convert their shares into shares of the Company’s common stock on a one-to-one basis without payment of additional consideration and are not redeemable unless by mutual consent. The majority of Series D preferred shares are held by the estate of John Lawrence, the previous President and Chairman of the Company.

The purpose of the Plan is to attract and retain the best available personnel for positions of substantial responsibility and to provide additional incentive to employees, directors and consultants to promote the success of the Company’s business. The maximum number of shares of common stock or options to purchase common stock that may be issued pursuant to the Plan is 500,000. At December 31, 2021 and 2020, 300,000 shares of the Company’s common stock had been previously issued under the Plan. There were no issuances under the Plan during 2021 and 2020. 11. Income and Other Taxes During the year ended December 31, 2021 and 2020, the Company recognized no income tax benefit (provision). Domestic and foreign components of net loss from operations before income taxes for the years ended December 31, 2021 and 2020, are as follows: The income tax benefit differs from the amount of income tax determined by applying the U.S. federal income tax rate to pre- tax net loss for the years ended December 31, 2021 and 2020 due to the following: At December 31, 2020 and 2019, the Company had net deferred tax assets as follows: F-17 https://www.sec.gov/Archives/edgar/data/101538/000165495422004348/uamy_10k.htm 62/67 2/26/23, 4:29 PM Table of Contents uamy_10k.htm United States Antimony Corporation and Subsidiaries Notes to Consolidated Financial Statements December 31, 2021 and 2020 At December 31, 2021 and 2020, the Company had deferred tax assets arising principally from net operating loss carry forwards for income tax purposes. As management cannot determine that it is more likely than not the benefit of the net deferred tax asset will be realized, a valuation allowance equal to 100% of the net deferred tax asset has been recorded at December 31, 2021 and 2020. At December 31, 2021, the Company has federal net operating loss (“NOL”) carry forwards of approximately $290,000 that expire at various dates between 2036 and 2037. In addition, the Company has federal NOL carry forwards of $666,000 that will never expire but utilization of which is limited to 80% of taxable income in any future year. The Company has Montana state NOL carry forwards of approximately $2.3 million which expire between 2022 and 2026, and Idaho state NOL carry forwards of approximately $1.4 million, which expire between 2033 and 2035. The Company has approximately $5.2 million of Mexican NOL carry forwards which expire between 2025 and 2030. In 2018, the Company acquired two subsidiaries have net operating loss carryforwards in Mexico of approximately $800,000. Due to limitations, it is likely that a portion of this carryforward will not be available to offset the Company’s future taxable income in Mexico. During the years ended December 31, 2021 and 2020, there were no material uncertain tax positions taken by the Company. The Company’s United States income tax filings are subject to examination for the years 2019 through 2021, and 2018 through 2021 in Mexico. The Company charges penalties on assessments to general and administrative expense and charges interest to interest expense. Mexican Tax Assessment In 2015, the Mexican tax authority (“SAT”) initiated an audit of the USAMSA’s 2013 income tax return. In October 2016, as a result of its audit, SAT assessed the Company $13.8 million pesos, which was approximately $666,400 in U.S. Dollars (“USD”) as of December 31, 2016. SAT’s assessment was based on the disallowance of specific costs that the Company deducted on the 2013 USAMSA income tax return. The assessment was settled in 2018 with no assessment against the Company. In early 2019, the Company was notified that SAT re-opened its assessment of USAMSA’s 2013 income tax return and, in November 2019, SAT assessed the Company $16.3 million pesos, which was approximately $795,000 USD as of December 31, 2021. Management reviewed the 2019 assessment notice from SAT and, similar to the earlier assessment, believes the findings have no merit. An appeal was filed by the Company in November 2019 suspending SAT from taking immediate action regarding the assessment. The Company posted a guarantee of the amount in March 2020 as is required under the appeal process. In August 2020, the Company filed a lawsuit against SAT for resolution of the process and, in December 2020, filed closing arguments. Management expects the appeal process to continue through 2022. At December 31, 2021, management assessed the possible outcomes for this tax audit and believes, based on discussions with its tax attorney in Mexico, that the most likely outcome will be that the Company will be successful in its appeal resulting in no tax due. Management determined that no amount should be accrued at December 31, 2021 or December 31, 2020 relating to this potential tax liability. There can be no assurance that the Company’s ultimate liability, if any, will not have a material adverse effect on the Company’s results of operations or financial position. If an issue addressed during the SAT audit is resolved in a manner inconsistent with management expectations, the Company will adjust its current net operating loss carryforward, or accrue penalties, interest, and tax associated with the assessment.

At that time, the Company applied for and was granted a Maquiladora (IMMEX), in accordance with a Manufacturing and Export Services Industry program offered by the Mexican government to attract and promote foreign investment in Mexico. With the IMMEX, all imported goods to Mexico that are also exported in altered form are exempt from the requirement of paying the 16% tax (IVA). The Company did not pay IVA on any of the imported coal used to process the Australian concentrates. In 2020, the Company was informed by the SAT that it owed the 16% IVA money for all the coal imported for the processing of the Australian concentrates. Additionally, there were penalties and fees that SAT added to the total amount. In late 2020, the Company filed a motion before the Taxpayer’s Defense Agency (PRODECON), but the motion was denied. To avoid exorbitant penalties, the Company elected to pay the assessed amount in early 2021. For the year ended December 31, 2020, the Company recognized an export tax expense of $1,120,730 and accrued a liability for this assessment. The amount was paid in early 2021. 12. Related-Party Transactions John Lawrence, the Company’s previous Chief Executive Officer and Chairman of the Board of Directors, rented equipment to the Company and charged the Company for lodging and meals provided to consultants, customers and other parties by an entity that Mr. Lawrence owned. The amount due to Mr. Lawrence as of December 31, 2020 was $171,017. During 2021, the Company paid the full amount of $171,017 to John Lawrence’s estate for reimbursement of these expenses. Expenses paid to Mr. Lawrence for the year ended December 31, 2020 were $1,533. During 2020, an advance of $56,215 due to John Lawrence was satisfied with the exercise of a warrant held by Mr. Lawrence for 250,000 shares of common stock at an exercise price of $0.25 or $62,500. During the year ended December 31, 2021, Russ Lawrence, President and Director, incurred expenses of $24,510 and charged the Company for lodging and meals provided to visiting Board of Directors by an entity that Russ Lawrence owns. During the year ended December 31, 2021, the Company paid Russ Lawrence $27,290, leaving a balance due of $1,846 which is included in accounts payable on the balance sheet. 13. Commitments and Contingencies From time to time, the Company is assessed fines and penalties by the Mine Safety and Health Administration (“MSHA”). Using appropriate regulatory channels, management may contest these proposed assessments. At December 31, 2021 and 2020, the Company had accrued liabilities of $Nil and $246, respectively, relating to such assessments. The Company pays various royalties on the sale of zeolite products. On a combined basis, royalties vary from 8%-13%. During the year ended December 31, 2021 and 2020, the Company had royalty expense of $262,861 and $224,875, respectively. At December 31, 2021 and 2020, the Company had accrued royalties payable of $346,242 and $434,981, respectively. The Company is currently in negotiations with certain royalty holders to modify the terms of the agreements.

Business Segments The Company is currently organized and managed by four segments, which represent the three operating units: United States antimony, Mexican antimony, United States zeolite, and precious metals. The Company’s other operating costs include general and administrative expenses, freight and delivery, and other non-production related costs. Other income and expense consist primarily of non-operating income and interest expense. The Madero smelter and Puerto Blanco mill at the Company’s Mexico operation brings antimony up to a finished product or an intermediate stage, which is then either shipped directly to customers or to the United States operation for finishing and sales at the Thompson Falls, Montana plant. The Zeolite operation produces zeolite near Preston, Idaho. Almost all of the sales of products from the United States antimony and zeolite operations are to customers in the United States. Precious metal recovered from the antimony process in the United States and Mexico is typically sold to customers in the United States and Canada. Segment disclosures regarding sales to major customers and for property, plant, and equipment are located in Notes 3 and 6, respectively.

CARES Act Loan On April 20, 2020, the Company received a loan of $443,400 pursuant to the Paycheck Protection Program (the “PPP”) under Division A, Title I of the CARES Act, which was enacted March 27, 2020. The loan, which was in the form of a Note dated April 20, 2020 had a maturity date on April 19, 2022 and an interest rate of 1% per annum. The loan was to be forgiven under the provisions of the CARES Act if the Company used the funds for qualifying expenses. Qualifying expenses included payroll costs, costs used to continue group health care benefits, rent and utilities. During the year ended December 31, 2021, the Company received notification that the loan had been forgiven. The amount of the loan, $443,400, was recognized as gain on forgiveness of the CARES Act loan. 16.
