Item 1. Description of Business

General

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 2020, 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 2021 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 (AM) which owns the San Miguel concession of the Los Juarez property. USAMSA has three divisions, (1) the Madero smelter in Coahuila, (2) the Puerto Blanco flotation mill and oxide circuit in Guanajuato and (3) the Los Juarez mineral deposit.

1

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 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.

●

As a vertically integrated company, we will have more control over our raw material costs.

Following is a five year schedule of our antimony sales:

Schedule of Antimony Sales
	Lbs Metal		Average
Year	Contained	$	Price/Lb
2020	815,310	$2,942,628	$3.61
2019	1,566,585	$5,450,649	$3.48
2018	1,486,120	$6,113,014	$4.11
2017	1,891,439	$7,588,470	$4.01
2016	2,936,880	$8,744,170	$2.98

Concentration of Sales:

During the years ended December 31, 2020 and 2019, the following sales were made to our three largest customers:

	For the Year Ended
Sales to Three	December 31,	December 31,
Largest Customers	2020	2019
Mexichem Specialty Compounds Inc.	$633,846	$1,823,194
GE Chaplin, Inc.	589,384	-
Nyacol Nanotechnologies	417,501	1,099,504
Kohler	345,899	1,132,674
	$1,986,630	$4,055,372
% of Total Revenues	38%	49%

In July of 2020, following a major change in management, the Company temporarily halted its sale of antimony to a few of its customers in order to minimize its losses during a period for which the antimony price was below production costs. The company in 2021 has since resumed sale to most of these customers and is experiencing a marked increase in the price of antimony.

Marketing:We employ full-time marketing personnel and have negotiated various commission-based sales agreements with other chemical distribution companies.

2

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
	Metal
	Contained
Year	Price
2020	$3.61
2019	$3.48
2018	$4.11
2017	$4.01
2016	$2.98

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. We constructed a new warehouse in 2018 to expedite our shipping and packaging for customers.

We have no "proven reserves" or "probable reserves" 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.

☐

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.

3

☐

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, 2020 and 2019, we have accrued $100,000 to fulfill our environmental responsibilities.

BRZ

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, 2020.

4

General

Reclamation activities at the Thompson Falls Antimony Plant have proceeded 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, 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, 2020, we employed 14 full-time employees in Montana. In addition, we employed 15 people at our zeolite plant in Idaho, and 27 employees at our mining, milling and smelting operation in Mexico. We no longer employ any contract miners 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 un-asserted 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. The range of reasonably possible losses from our exposure to environmental liabilities in excess of amounts accrued to date cannot be reasonably estimated at this time.

5

We have accruals for asset retirement obligations and environmental obligations.

We have accruals totaling $291,719 on our balance sheet at December 31, 2020, 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 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 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, 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.

The mineral rights for the concessions San Miguel I and II were purchased by a USAC subsidiary, Antimonio de Mexico, S. A. de C. V (AM), 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)

2.

San Juan I and II are concessions owned by AM and include 466 hectares (1,152 acres)

3.

San Juan III is held by a lease agreement by AM 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).

6

The concessions collectively constitute 720 hectares (1,780 acres). The claims are accessed by roads that lead to highways.

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.

7

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.

8

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. 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.

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 twenty to thirty metric tons of direct shipping ore or concentrates per day, depending on the quality of the feedstock. If the feedstock is in the range of 45% antimony, 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 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 or finished oxide directly to customers or shipped to our Montana plant to produce finished Antimony products and precious metals. Access to the plant is by road and railroad. Set forth below are location maps:

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.

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

There are two lines to produce coarse products:

●

 Line 1 is a closed circuit with a 100 HP vertical shaft impactor and a 5 deck Midwestern Multi Vibe high frequency screen.

●

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.

11

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.

Overview

Company-wide

For the year ended December 31, 2020, we reported net loss of $3,286,804 after depreciation and amortization of $885,843, compared to a net loss of $3,672,891 for 2019 after depreciation and amortization of $895,990. Our company-wide EBITDA was a negative $2,400,961 for 2020, compared to a negative EBITDA of $2,776,901 for 2019.

Net non-cash expense items for 2020 totaled $1,317,644 and included $318,502 for the loss on mineral properties, $885,843 for depreciation and amortization, $106,108 for stock-based director compensation, and $7,191 for other items.

Net non-cash expense items for 2019 totaled $2,653,757 and included $1,410,736 for the loss on abandonment of mineral properties, $895,990 for depreciation and amortization, $54,112 for amortization of debt discount, $134,375 for stock-based director compensation, $136,000 for stock-based employee compensation, $16,396 for the write-down of inventory, and $6,148 for other items.

During the year ending December 31, 2020, the following transactions had a material impact on the Company’s net loss.

●

In July of 2020, USAMSA elected to relinquish its lease agreement with the Wadley mines. This decision, which resulted in a loss on mineral properties of $318,502 in 2020, was made principally because the exclusivity rights to purchase ore were not being honored. Antimony purchases were suspended for a time following this event and have been re-established in early 2021. Ore purchased from the Wadley mines is now on a net smelter return basis.

●

The Company was notified of delinquent export tax due associated with antimony production in Mexico prior to 2018. In 2020, the Company recognized an expense for the amount due of approximately $1.2 million which was paid in February 2021.

During the year ending December 31, 2019, the following transaction had a material impact on the Company’s net loss.

●

During the fourth quarter of 2019, it was decided to abandon two mining concessions in Mexico, known as the Guadalupe mine and the Soyatal mine. This decision was prompted by the low prices for antimony and the expected cost to develop the properties. The effect of abandoning the properties was a non-cash loss of $1,410,736 which was the carrying value of the mineral properties less the balance of related debt.

13

Antimony Sales

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 is, 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 are 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.

During 2019, we saw our average sale price decrease by $0.63 per pound from an average price of $4.11 per pound for 2018 to $3.48 per pound for 2019. During 2019, our raw material from our North American supplier increased by approximately 100,000 pounds and our supply of raw material from our Mexican mines decreased by approximately 20,000 pounds. Even though our sales volume increased, our total sales of antimony decreased due to the decrease in our sales price. This resulted in estimated decreased sales of approximately $662,000. Normal shipments from our North American supplier resumed in 2019 at a lower level than we expected, and we do not expect an increase from this supplier in the near future.

In the third quarter of 2019, we renegotiated our sodium antimonite supply agreement from our North American supplier to recognize that antimony prices were in a world-wide slump, and that our general and administrative costs were a larger percent of our revenues than they were under the previous agreement. The new price agreement was implemented in the third quarter of 2019, and resulted in lower antimony production costs and an improved cash flow for 2019 and better expectations for the North American operations going forward. The Company is currently engaged in a renewal of the contract with this supplier. The nature of the contract will likely be altered in order to establish a better agreement for both parties.

Zeolite Sales

Our sales volume of zeolite in 2020 was 3,019 tons less than we sold in 2019, a decrease of 22%. Our average sales price increased by approximately $6 per ton, from $192 per ton in 2019 to $199 per ton in 2020 (3.6%). During 2020, total sales of zeolite decreased by $504,294 from 2019. The zeolite division had an EBIDTA of $445,481 for 2020, compared to an EBITDA of $683,936 for 2019. Net income decreased from $497,470 in 2019 to $262,861 in 2020 ($234,609).

Our sales volume of zeolite in 2019 was 641 tons less than we sold in 2018, a decrease of 4.5%. Our average sales price increased by approximately $6 per ton, from $186 per ton in 2018 to $192 per ton in 2019 (2.7%). During 2019, total sales of zeolite decreased by $43,827 from 2018. The zeolite division had an EBIDTA of $683,936 for 2019, compared to an EBITDA of $638,764 for 2018. Net income increased from $449,961 in 2018 to $497,470 in 2019, approximately $47,000.

During the period ending December 31, 2020, the most significant factors affecting our financial performance were as follows:

●

The death of John Lawrence, the Company’s previous President and Chairman, which created the opportunity to renegotiate existing supply and processing contracts,

●

The continuing decline of antimony prices,

●

An assessment against US Antimony from the Mexican tax authority (SAT) in the amount of $1,120,730 regarding a lawsuit the Company had been in involved in since 2016.

●

A private placement of 5,742,858 shares of the Company’s common stock sold in July of 2020.

●

A 50% decrease in Canadian supply of sodium antimonate.

●

The consequences of the Covid-19 pandemic to antimony and zeolite sales and corresponding increase costs of freight.

During the period ended December 31, 2019, the most significant event affecting our financial performance was the continued low price of antimony. This decrease in prices caused us to re-evaluate our commitment to the two antimony mines we were purchasing in Mexico. We made the decision that with the depressed prices and the cost of developing the mines, it was in our best interest to abandon these properties and look at re-acquiring them in the future if antimony prices improved. It was decided that our resources should be directed to completing our precious metals facility at Puerto Blanco and starting precious metals production in 2021. In connection with the low antimony prices, we negotiated a lower cost agreement with our North American supplier which will help us with future cash flow.

Our plan for the remainder of 2021 is to process approximately:

●

1,300 tons of mined rock from the Los Juarez property. 2,000 tons have already been moved to the Puerto Blanco facility. It is estimated that we have 10,000 tons of mined rock at the Los Juarez property.

●

At least 720 tons of ore from the Wadley mines at the Madero Smelting facility.

●

300 tons of milled tailings at the Puerto Blanco facility.

●

60 tons of stibnite ore at Puerto Blanco facility for the generation of concentrates specifically for the production of antimony trisulfide for the Defense Logistic Agency (DLA).

In addition to the processing goals stated above, US Antimony intends to continue to improve its production capacity and sales of zeolite at its subsidiary Bear River Zeolite (BRZ). Funds obtained in early 2021 from two public placements of stock will assist greatly to this goal as well as the improvement of the facilities in Madero, Thompson Falls, Puerto Blanco, and Los Juarez.

In 2020, we only received 50% of our expected supply from North American sources. We anticipated increasing the raw material from Mexico and the resumption of normal shipments from our North American supplier in 2019, but these plans did not materialize due to low overall metal prices and the low antimony prices in particular.

In both 2020 and 2019, the Puerto Blanco mill circuits were utilized less than 2% of their capacity, but with the completion of the cyanide leach circuit we expect it to be fully utilized processing precious metals ore from the Los Juarez mine. Some antimony will be realized as a by-product of processing the Los Juarez ore. In 2020, US Antimony has been involved in renegotiating its supply contract with its North American source, that will likely result in a mutual improvement in the supply contract. Additionally, the price of antimony in early 2021 is double what it was in 2019.

17

The estimated recovery of precious metals per metric ton, after the caustic leach and cyanide leach circuits, is as follows at Los Juarez:

Schedule of Los Juarez

recovery values	Metal	Assay	Recovery	Value	Value/Mt
	Gold	0.035 opmt	87.40%	$1,732/oz	$52.98
	Silver	3.27 opmt	64.30%	$25.90/oz	$54.46
	Antimony	0.652%	41.80%	$5.23/lb	$31.41
	Total				$138.85

The following are highlights of the significant changes during 2020:

Antimony:

●

The sale of antimony during 2020 was 815,310 pounds compared to 1,566,585 pounds in 2019, a decrease of 751,275 pounds (48%).

●

The average sales price of antimony during 2020 was $3.61 per pound compared to $3.48 during 2019, an increase of $0.13 per pound (3.6%). During the beginning of 2021, the Rotterdam price of antimony is approximately $5.23 per pound.

●

The metallurgical problem with the Los Juarez concentrates has been solved with the cyanide and caustic leach plants, and initial production will begin. This allowed the preliminary testing of the cyanide leach circuit to occur in 2020. The Company plans to process both 1,300 tons of Los Juarez ore and 300 tons of milled tailings through this cyanide leach circuit during 2021.

●

The net loss for antimony sold was $4.46 per pound in 2020.

●

Our cost of goods sold for antimony decreased from $6,973,691 in 2019 to $3,147,954 in 2020. This was primarily due to the decrease in antimony production during 2020 in response to the lower price of antimony, and halting production at the Wadley facility.

●

Our cost of production for the years ended December 31, 2020 and 2019 included metallurgical testing at Puerto Blanco and Madero, Mexico, and to a lesser degree, our plant in Thompson Falls, Montana.

●

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 from ore from the Wadley mine in 2019. Production from Madero during 2020 and 2019 was primarily from our own Mexican properties, and although we only received 50% of expected raw materials from our North American supplier, we purchased a significant portion of the raw materials for our smelter in Montana.

●

We produced ingots of antimony metal to be shipped directly to customers from our Madero smelter in 2020. We intend to increase this for 2021 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.

Zeolite:

During 2020, the Company sold 10,661 tons compared to 13,680 tons in 2019, a decrease of 3,019 tons (22%). BRZ realized a net income of $262,862 in 2020 after depreciation of $182,620 compared to a net income of $497,470 in 2019 after depreciation of $186,466.

General and Administrative:

General and administrative costs, as reported in our statement of operations, include fees paid to directors through stock-based compensation, office expenses, and fees to the NYSE AMERICAN, and other non-operating costs. The combined general and administrative costs were 11.6%, and 8.2%, of sales for 2020 and 2019, respectively.

Current assets increased due to an increase in cash and cash equivalents. Our current liabilities increased by $501,862, which included a decrease of approximately $584,000 in accounts payables and payables to related parties, but an overall increase due to Mexican export tax liability. Capital improvements were paid for with cash and debt.

For the year ending December 31, 2021, we are planning to use funds acquired from the two stock offerings raised in Q1 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.

Going Concern Consideration

At December 31, 2020, the Company’s consolidated financial statements show negative working capital of approximately $2.7 million and an accumulated deficit of approximately $32.7 million.  With the exception of 2018, the Company has incurred losses for the past several years.  The net income in 2018 was primarily due to non-recurring events which contributed approximately $2.5 million to net income. The continuing losses are principally a result of the Company’s antimony operations due to both depressed antimony prices and production costs incurred in Mexico.  To improve conditions, the Company plans to continue searching for areas to reduce these production costs.   Management expects improvement in cash flow in 2021 from the sale of precious metals extracted from the leach circuit that came on line in Mexico in the second half of 2020.  

Over the past several years, the Company has been able to make required principal payments on its debt from cash generated from operations.  The Company is confident it can make debt payments when due.  In March 2020, the Company applied for and received funds from a note payable under the CARES Act for $443,400. In July 2020 the Company was successful in raising $1,813,068 from the sale of shares of common stock and warrants to fund capital projects in Mexico. In the first quarter of 2021, the Company raised $23,497,180 (net of $1,499,820 in agent’s fees) from sale of shares of its common stock and warrants that will be used for general corporate purposes, working capital, and to fund a geochemical, geological and geophysical program at the Los Juarez property. With the funds raised, management believes the Company has sufficient funds to sustain its operations and meet its financial obligations during the 12 months following the date of issuance of the consolidated financial statements.

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. At December 31, 2011, we made an estimate that the cost of the machine and man hours probable to be needed to put our properties in the condition required by our permits once we cease operations would be $134,000. For purposes of the estimate, we used a probable life of 20 years and costs that, initially, are comparable to rates that we would incur at the present. We are adding to (an accretion of 6%) the liability each year, and amortizing the asset over 20 years ($6,700 annually), which decreases our net income in total each year. 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.

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 Accounting 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 Accounting 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 Interim CEO and Interim President, 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, 2020. 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 Principal Executive 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 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.

21

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, 2020, 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, 2020.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the board of directors of United States Antimony Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of United States Antimony Corporation (the "Company") as of December 31, 2020 and 2019, the related consolidated statements of operations, changes in stockholders’ equity and cash flows for each of the years then ended, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, 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

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

F-1

Assessment of Properties, Plants and Equipment for Impairment

As described in Note 2 to the consolidated financial statements, management reviews and evaluates the net carrying value of properties, plants and equipment for impairment upon the occurrence of events or changes in circumstances that indicate that the related carrying amounts may not be recoverable. If deemed necessary based on this review and evaluation, management performs a test for impairment. The determination of whether an impairment has occurred is based on an estimate of undiscounted future net cash flows attributable to the assets as compared to the carrying value of the assets.

In its review and evaluation, management determined that the carrying amount of properties, plants and equipment located in Mexico (“Mexican PPE”), which has a carrying value of $8,438,413 as of December 31, 2020, may not be recoverable and prepared an undiscounted future net cash flows analysis to determine recoverability. Based on its analysis, management concluded that the undiscounted future net cash flow exceeded the net carrying value of the Mexican PPE and an impairment was not recognized.

The undiscounted future net cash flow analysis prepared by management is sensitive to assumptions including quantities of recoverable minerals, expected metal prices, production levels, and estimated operating costs of production and capital.

We identified the impairment assessment of the Mexican PPE as a critical audit matter due to the materiality of the Mexican PPE balance, the high degree of auditor judgment and an increased level of effort when performing audit procedures to evaluate the reasonableness of management’s assumptions in determining the undiscounted future net cash flows. The primary procedures we performed to address this critical audit matter included:

● Evaluation of the Company’s identification of significant events or changes in circumstances that have occurred indicating the underlying Mexican PPE may not be recoverable by performing an independent assessment.

● Discussion with management of future business plans for the Mexican PPE and assessment as to whether the undiscounted future net cash flow analysis was consistent with the plans.

● Comparison of key assumptions utilized in the current undiscounted future net cash analysis to assumptions used in past analyses and assessed whether the current analysis appropriately reflected the impact of changes to the Company’s business plans and operations, current metal prices, actual operating costs, and industry-specific events.

● In addition to ensuring key assumptions were consistent with evidence obtained in other areas of the audit, evaluation of the significant assumptions and judgements used in the Company’s analysis including:

o

estimated metal price through comparison to publicly available industry information,

o

estimated future operating and development costs through comparison to the Company’s historical costs, and

o

estimated quantities of recoverable minerals through comparison to historical data and based on our knowledge and experience with the Company.

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. As long as they are required, the operational practices implemented could have an adverse impact on our operating results due to deferred production and revenues or additional costs. The negative impact of COVID-19 remains uncertain, including on overall business and market conditions. The impact of these restrictions on our business has been minimal. It is possible that future restrictions could have an adverse impact on our operations or financial results beyond 2020.

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.

F-7

Summary of Significant Accounting Policies, continued:

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.

Restricted Cash

Restricted cash at December 31, 2020 and 2019 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, 2020 and 2019 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.

Going Concern Consideration

At December 31, 2020, the Company’s consolidated financial statements show negative working capital of approximately $2.7 million and an accumulated deficit of approximately $32.7 million.  With the exception of 2018, the Company has incurred losses for the past several years.  The net income in 2018 was primarily due to non-recurring events which contributed approximately $2.5 million to net income. The continuing losses are principally a result of the Company’s antimony operations due to both depressed antimony prices and production costs incurred in Mexico.  To improve conditions, the Company plans to continue searching for areas to reduce these production costs.   Management expects improvement in cash flow in 2021 from the sale of precious metals extracted from the leach circuit that came on line in Mexico in the second half of 2020.  

F-8

Summary of Significant Accounting Policies, continued:

Over the past several years, the Company has been able to make required principal payments on its debt from cash generated from operations. The Company is confident it can make debt payments when due. In March 2020, the Company applied for and received funds from a note payable under the CARES Act for $443,400. In July 2020 the Company was successful in raising $1,813,068 from the sale of shares of common stock and warrants to fund capital projects in Mexico. In the first quarter of 2021, the Company raised $23,497,180 (net of $1,499,820 in agent’s fees) from sale of shares of its common stock and warrants that will be used for general corporate purposes, working capital, and to fund a geochemical, geological and geophysical program at the Los Juarez property. With the funds raised, management believes the Company has sufficient funds to sustain its operations and meet its financial obligations during the 12 months following the date of issuance of the consolidated financial statements.

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.

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.

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.

Revenue Recognition

Products consist of the following:

●

Antimony: includes antimony oxide, sodium antimonate, antimony trisulfide, and antimony metal

●

Zeolite: includes coarse and fine zeolite crushed in various sizes

●

Precious Metals: includes unrefined and refined gold and silver

For antimony and zeolite products, revenue is recognized upon the completion of the performance obligation which is met when the transaction price can be reasonably estimated and revenue is recognized generally at the time when risk is transferred. 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.

Summary of Significant Accounting Policies, continued:

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.

Income (Loss) Per Common Share

Basic earnings per share is calculated by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. 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 2019, potentially dilutive common stock equivalents not included in the calculation of diluted earnings per share because they were anti-dilutive are as follows:

	December 31, 2020	December 31, 2019
Warrants	6,194,899	702,041
Convertible preferred stock	1,751,005	1,751,005
Total possible dilution	7,945,904	2,453,046

Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, certificates of deposits, restricted cash, due to factor (included in accrued liabilities), notes payable to bank, and notes payable. The carrying value of these instruments approximates fair value based on their contractual terms.

F-11

Summary of Significant Accounting Policies, continued:

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 1 uses 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.

Reclassifications

Certain reclassifications have been made to conform the prior year’s data to the current year’s presentation. These reclassifications have no effect on previously reported operations, stockholders’ equity or cash flows.

Recent Accounting Pronouncements

Accounting Standards Updates Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Auditing Standards Update (“ASU”) No. 2018-13 Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The update removes, modifies and makes additions to the disclosure requirements on fair value measurements. The update was adopted as of January 1, 2020, and its adoption did not have a material impact on the Company’s consolidated financial statements.

Accounting Standards Updates to Become Effective in Future Periods

In December 2019, the FASB issued 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 is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. Management is evaluating the impact of this update on the Company’s consolidated financial statements.

In August 2020, the FASB issued ASU No. 2019-12Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The update is to address issues identified as a result of the complexity associated with applying generally accepted accounting principles for certain financial instruments with characteristics of liabilities and equity. The update is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years and with early adoption permitted. Management is evaluating the impact of this update on the Company’s consolidated financial statements.

Accounts Receivable and Due to Factor

The Company factors designated trade receivables pursuant to a factoring agreement with LSC Funding Group L.C., an unrelated factor (the “Factor”).  The agreement is for a term of one year with automatic renewal for additional one-year terms. The agreement specifies that eligible trade receivables are factored with recourse. The performance of all obligations and payments to the factoring company was personally guaranteed by John C. Lawrence, the Company’s previous President and Chairman of the Board of Directors. The existing agreement will be addressed in 2021 to account for Mr. Lawrence’s death and that impact on the personal guarantee. Selected trade receivables are submitted to the Factor, and the Company receives 85% of the face value of the receivable by wire transfer. Upon payment by the customer, the remainder of the amount due is received from the Factor, less a one-time servicing fee of 2% for the receivables factored.  This servicing fee is recorded on the consolidated statement of operations in the period of sale to the Factor.  

Trade receivables assigned to the Factor are carried at the original invoice amount less an estimate made for doubtful accounts.  Under the terms of the recourse provision, the Company is required to reimburse the Factor, upon demand, for factored receivables that are not paid on time.  Accordingly, these receivables are accounted for as a secured financing arrangement and not as a sale of financial assets.  

Receivables, net of allowances, are presented as current assets and the amount potentially due to the Factor is included in current accrued liabilities.

Accounts Receivable	December 31, 2020	December 31, 2019
Accounts receivable - non factored	$222,034	$273,573
Accounts receivable - factored with recourse	16,600	10,880
Accounts receivable - net	$238,634	$284,453

The Company’s precious metals segment includes properties, plants and equipment in both the United States and Mexico. In the third quarter of 2020, the Company decided not to renew the lease at the Wadley Mining district in Mexico due to continuing low market price for antimony and to reduce Mexican antimony production while seeking other lower cost sources of antimony ore and concentrates. The net carrying value of the mineral lease of $318,502 was recognized as a loss on mineral properties during the year ended December 31, 2020.

In the fourth quarter of 2019, the Company abandoned the Soyatal and Guadalupe mineral properties in Mexico. The net carrying value of the mineral properties of $2,937,259 less the outstanding related notes payable balances, resulted in a loss on mineral properties of $1,410,736 which was recognized during the year ended December 31, 2019.

At December 31, 2020 and 2019, the Company had $755,978 and $1,306,579, respectively, of assets that were not yet placed in service and have not yet been depreciated.

Hillgrove Advances Payable

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 the past three years. The agreement requires the Company to pay the advance balance after Hillgrove issues a stop notice. Payments would begin 90 days after the stop notice issue date and be made in six equal and quarterly installments. The balance of the advance liability due to Hillgrove was $1,134,221 at both December 31, 2020 and 2019. Hillgrove was acquired by Red River Resources LTD (“Red River”) during 2019. Although the Company has not received a stop notice through the date these financial statements were issued, management has determined that one is likely forthcoming in 2021. Based on management’s assessment of likelihood and the payment terms of the agreement, $378,074 of the balance is classified as current as of December 31, 2020 and 2019.

At December 31, 2020 and 2019, the liquidation preference for Series D preferred stock was $5,084,770 and $5,043,622, 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.

2000 Stock Plan

In January 2000, the Company's Board of Directors resolved to create the United States Antimony Corporation 2000 Stock Plan ("the Plan"). 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, 2020 and 2019, 300,000 shares of the Company's common stock had been previously issued under the Plan. There were no issuances under the Plan during 2020 and 2019.

Income and Other Taxes

During the year ended December 31, 2020 and 2019, 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, 2020 and 2019, are as follows:

	2020	2019
Domestic	$564,424	$462,292
Foreign	(3,851,228)	(4,135,183)
Total	$(3,286,804)	$(3,672,891)

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, 2020 and 2019 due to the following:

	2020	2019
Tax benefit at federal statutory rate	$(690,229)	$(771,307)
State income tax effect	(120,541)	(177,435)

Income and Other Taxes, continued:

At December 31, 2020 and 2019, 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, 2020 and 2019.

At December 31, 2020, the Company has federal net operating loss (“NOL”) carry forwards of approximately $0.7 million that expire at various dates between 2034 and 2037. In addition, the Company has federal NOL carry forwards of $1.1 million 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 $3.4 million which expire between 2021 and 2027, and Idaho state NOL carry forwards of approximately $2.4 million, which expire between 2034 and 2039. The Company has approximately $7.9 million of Mexican NOL carry forwards which expire between 2024 and 2029.

In 2018, the Company acquired two subsidiaries have net operating loss carryforwards in Mexico of approximately $800,000. Due to tax code 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, 2020 and 2019, 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 2017 through 2019, and 2016 through 2019 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 Company engaged accountants and tax attorneys in Mexico to defend its position. 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 $821,000 USD as of December 31, 2020.

Management reviewed the 2019 assessment notice from SAT and, similar to the earlier assessment, believes the findings have no merit. The Company engaged a tax attorney in Mexico to defend its position. 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 2021.

At December 31, 2020, 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, 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.

Other Taxes

In 2016, the Company, through its wholly owned subsidiary USAMSA, imported coal from the United States to its smelter in Mexico to process Australian concentrates associated with the Hillgrove agreement (Note 10). At that time, the Company applied for and was granted a Maquiladora (IMMEX) which the Company believed provided an exemption from paying a 16% value-added tax (IVA) on imported goods to Mexico that were ultimately exported in altered form. With this understanding, the Company did not pay IVA on coal it imported to process the Australian concentrates. In 2020, the Company was informed by the SAT that it owed the 16% IVA for the coal it had imported from 2016 to 2018. The initial assessment from SAT included penalties and fees. In late 2020, the Company filed a motion before the Taxpayer's Defense Agency but the motion was denied. To avoid incurring additional 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. Upon payment in early 2021, the Company believes that this matter is settled.

14.

Related-Party Transactions

On June 16, 2020, John C. Lawrence, the Company’s previous Chief Executive Officer and Chairman of the Board of Directors, passed away. The Company’s Executive Vice-President, John C. Gustaven, has been appointed to interim Chief Executive Officer. Russell Lawrence, son of Mr. Lawrence, has been appointed the Company’s interim President and is the executor of Mr. Lawrence’s estate.

John Lawrence 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 and 2019 was $171,017 and $156,975, respectively. Expenses paid to Mr. Lawrence for the years ended December 31, 2020 and 2019 were $1,533 and $9,799, respectively

During 2019, John Lawrence made advances to the Company totaling $227,200, of which $170,985 had been repaid as of December 31, 2020, leaving a balance of $56,215. During 2020, a portion of this amount was in the form of 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.

John C. Gustaven advanced the Company $10,200 during 2019, of which $10,000 had been repaid as of December 31, 2020, leaving a balance of $200.

Commitments and Contingencies

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, 2020 and 2019, the Company had royalty expense of $224,875 and $266,388, respectively. At December 31, 2020 and 2019, the Company had accrued royalties payable of $434,981 and $280,314, 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. It is anticipated that the loan will be forgiven under the provisions of the CARES Act because the Company used the funds for qualifying expenses. Qualifying expenses included payroll costs, costs used to continue group health care benefits, rent, and utilities. The amount of the PPP loan will be recognized as gain on forgiveness of the CARES Act loan in the period the Company receives formal notification of forgiveness.

Subsequent Events

In the first quarter of 2021, the Company raised $23,497,180 (net of $1,499,820 in agent’s fees) in two separate transactions from sale of shares of its common stock and warrants for general corporate purposes, working capital, and to fund a geochemical, geological and geophysical program at the Los Juarez property.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

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. As long as they are required, the operational practices implemented could have an adverse impact on our operating results due to deferred production and revenues or additional costs. The negative impact of COVID-19 remains uncertain, including on overall business and market conditions. The impact of these restrictions on our business has been minimal. It is possible that future restrictions could have an adverse impact on our operations or financial results beyond 2020.

2. Summary of Significant Accounting Policies

Accounting Policies [Abstract]

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.

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.

Restricted Cash

Restricted cash at December 31, 2020 and 2019 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, 2020 and 2019 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.

Going Concern Consideration

At December 31, 2020, the Company’s consolidated financial statements show negative working capital of approximately $2.7 million and an accumulated deficit of approximately $32.7 million.  With the exception of 2018, the Company has incurred losses for the past several years.  The net income in 2018 was primarily due to non-recurring events which contributed approximately $2.5 million to net income. The continuing losses are principally a result of the Company’s antimony operations due to both depressed antimony prices and production costs incurred in Mexico.  To improve conditions, the Company plans to continue searching for areas to reduce these production costs.   Management expects improvement in cash flow in 2021 from the sale of precious metals extracted from the leach circuit that came on line in Mexico in the second half of 2020.  

Over the past several years, the Company has been able to make required principal payments on its debt from cash generated from operations. The Company is confident it can make debt payments when due. In March 2020, the Company applied for and received funds from a note payable under the CARES Act for $443,400. In July 2020 the Company was successful in raising $1,813,068 from the sale of shares of common stock and warrants to fund capital projects in Mexico. In the first quarter of 2021, the Company raised $23,497,180 (net of $1,499,820 in agent’s fees) from sale of shares of its common stock and warrants that will be used for general corporate purposes, working capital, and to fund a geochemical, geological and geophysical program at the Los Juarez property. With the funds raised, management believes the Company has sufficient funds to sustain its operations and meet its financial obligations during the 12 months following the date of issuance of the consolidated financial statements.

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.

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.

Revenue Recognition

Products consist of the following:

● Antimony: includes antimony oxide, sodium antimonate, antimony trisulfide, and antimony metal

● Zeolite: includes coarse and fine zeolite crushed in various sizes

● Precious Metals: includes unrefined and refined gold and silver

For antimony and zeolite products, revenue is recognized upon the completion of the performance obligation which is met when the transaction price can be reasonably estimated and revenue is recognized generally at the time when risk is transferred. 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.

Income (Loss) Per Common Share

Basic earnings per share is calculated by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. 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 2019, potentially dilutive common stock equivalents not included in the calculation of diluted earnings per share because they were anti-dilutive are as follows:

	December 31, 2020		December 31, 2019
Warrants		6,194,899		702,041
Convertible preferred stock		1,751,005		1,751,005
Total possible dilution		7,945,904		2,453,046

Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, certificates of deposits, restricted cash, due to factor (included in accrued liabilities), notes payable to bank, and notes payable. 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 1 uses 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.

Reclassifications

Certain reclassifications have been made to conform the prior year’s data to the current year’s presentation. These reclassifications have no effect on previously reported operations, stockholders’ equity or cash flows.

Recent Accounting Pronouncements

Accounting Standards Updates Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Auditing Standards Update (“ASU”) No. 2018-13 Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The update removes, modifies and makes additions to the disclosure requirements on fair value measurements. The update was adopted as of January 1, 2020, and its adoption did not have a material impact on the Company’s consolidated financial statements.

Accounting Standards Updates to Become Effective in Future Periods

In December 2019, the FASB issued 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 is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. Management is evaluating the impact of this update on the Company’s consolidated financial statements.

In August 2020, the FASB issued ASU No. 2019-12 Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The update is to address issues identified as a result of the complexity associated with applying generally accepted accounting principles for certain financial instruments with characteristics of liabilities and equity. The update is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years and with early adoption permitted. Management is evaluating the impact of this update on the Company’s consolidated financial statements.

4. Accounts Receivable and Due to Factor

Receivables [Abstract]

Accounts Receivable and Due to Factor

The Company factors designated trade receivables pursuant to a factoring agreement with LSC Funding Group L.C., an unrelated factor (the “Factor”).  The agreement is for a term of one year with automatic renewal for additional one-year terms. The agreement specifies that eligible trade receivables are factored with recourse. The performance of all obligations and payments to the factoring company was personally guaranteed by John C. Lawrence, the Company’s previous President and Chairman of the Board of Directors. The existing agreement will be addressed in 2021 to account for Mr. Lawrence’s death and that impact on the personal guarantee. Selected trade receivables are submitted to the Factor, and the Company receives 85% of the face value of the receivable by wire transfer. Upon payment by the customer, the remainder of the amount due is received from the Factor, less a one-time servicing fee of 2% for the receivables factored.  This servicing fee is recorded on the consolidated statement of operations in the period of sale to the Factor.  

Trade receivables assigned to the Factor are carried at the original invoice amount less an estimate made for doubtful accounts.  Under the terms of the recourse provision, the Company is required to reimburse the Factor, upon demand, for factored receivables that are not paid on time.  Accordingly, these receivables are accounted for as a secured financing arrangement and not as a sale of financial assets.  

Receivables, net of allowances, are presented as current assets and the amount potentially due to the Factor is included in current accrued liabilities.

Income Taxes

During the year ended December 31, 2020 and 2019, 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, 2020 and 2019, 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, 2020 and 2019 due to the following:

	2020			2019

Net deferred tax asset	$	-		$	-

At December 31, 2020 and 2019, 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, 2020 and 2019.

At December 31, 2020, the Company has federal net operating loss (“NOL”) carry forwards of approximately $0.7 million that expire at various dates between 2034 and 2037. In addition, the Company has federal NOL carry forwards of $1.1 million 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 $3.4 million which expire between 2021 and 2027, and Idaho state NOL carry forwards of approximately $2.4 million, which expire between 2034 and 2039. The Company has approximately $7.9 million of Mexican NOL carry forwards which expire between 2024 and 2029.

In 2018, the Company acquired two subsidiaries have net operating loss carryforwards in Mexico of approximately $800,000. Due to tax code 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, 2020 and 2019, 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 2017 through 2019, and 2016 through 2019 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 Company engaged accountants and tax attorneys in Mexico to defend its position. 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 $821,000 USD as of December 31, 2020.

Management reviewed the 2019 assessment notice from SAT and, similar to the earlier assessment, believes the findings have no merit. The Company engaged a tax attorney in Mexico to defend its position. 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 2021.

At December 31, 2020, 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, 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.

Other Taxes

In 2016, the Company, through its wholly owned subsidiary USAMSA, imported coal from the United States to its smelter in Mexico to process Australian concentrates associated with the Hillgrove agreement (Note 10). At that time, the Company applied for and was granted a Maquiladora (IMMEX) which the Company believed provided an exemption from paying a 16% value-added tax (IVA) on imported goods to Mexico that were ultimately exported in altered form. With this understanding, the Company did not pay IVA on coal it imported to process the Australian concentrates. In 2020, the Company was informed by the SAT that it owed the 16% IVA for the coal it had imported from 2016 to 2018. The initial assessment from SAT included penalties and fees. In late 2020, the Company filed a motion before the Taxpayer's Defense Agency but the motion was denied. To avoid incurring additional 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. Upon payment in early 2021, the Company believes that this matter is settled.

Segment Reporting [Abstract]

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. It is anticipated that the loan will be forgiven under the provisions of the CARES Act because the Company used the funds for qualifying expenses. Qualifying expenses included payroll costs, costs used to continue group health care benefits, rent, and utilities. The amount of the PPP loan will be recognized as gain on forgiveness of the CARES Act loan in the period the Company receives formal notification of forgiveness.

2. Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2020

Accounting Policies [Abstract]

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.

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.

Restricted Cash

Restricted cash at December 31, 2020 and 2019 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, 2020 and 2019 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.

Going Concern Consideration

At December 31, 2020, the Company’s consolidated financial statements show negative working capital of approximately $2.7 million and an accumulated deficit of approximately $32.7 million.  With the exception of 2018, the Company has incurred losses for the past several years.  The net income in 2018 was primarily due to non-recurring events which contributed approximately $2.5 million to net income. The continuing losses are principally a result of the Company’s antimony operations due to both depressed antimony prices and production costs incurred in Mexico.  To improve conditions, the Company plans to continue searching for areas to reduce these production costs.   Management expects improvement in cash flow in 2021 from the sale of precious metals extracted from the leach circuit that came on line in Mexico in the second half of 2020.  

Over the past several years, the Company has been able to make required principal payments on its debt from cash generated from operations. The Company is confident it can make debt payments when due. In March 2020, the Company applied for and received funds from a note payable under the CARES Act for $443,400. In July 2020 the Company was successful in raising $1,813,068 from the sale of shares of common stock and warrants to fund capital projects in Mexico. In the first quarter of 2021, the Company raised $23,497,180 (net of $1,499,820 in agent’s fees) from sale of shares of its common stock and warrants that will be used for general corporate purposes, working capital, and to fund a geochemical, geological and geophysical program at the Los Juarez property. With the funds raised, management believes the Company has sufficient funds to sustain its operations and meet its financial obligations during the 12 months following the date of issuance of the consolidated financial statements.

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.

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.

Revenue Recognition

Products consist of the following:

● Antimony: includes antimony oxide, sodium antimonate, antimony trisulfide, and antimony metal

● Zeolite: includes coarse and fine zeolite crushed in various sizes

● Precious Metals: includes unrefined and refined gold and silver

For antimony and zeolite products, revenue is recognized upon the completion of the performance obligation which is met when the transaction price can be reasonably estimated and revenue is recognized generally at the time when risk is transferred. 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.

Income (Loss) Per Common Share

Basic earnings per share is calculated by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. 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 2019, potentially dilutive common stock equivalents not included in the calculation of diluted earnings per share because they were anti-dilutive are as follows:

	December 31, 2020		December 31, 2019
Warrants		6,194,899		702,041
Convertible preferred stock		1,751,005		1,751,005
Total possible dilution		7,945,904		2,453,046

Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, certificates of deposits, restricted cash, due to factor (included in accrued liabilities), notes payable to bank, and notes payable. 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 1 uses 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

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 1 uses 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.

Reclassifications

Certain reclassifications have been made to conform the prior year’s data to the current year’s presentation. These reclassifications have no effect on previously reported operations, stockholders’ equity or cash flows.

Recent Accounting Pronouncements

Accounting Standards Updates Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Auditing Standards Update (“ASU”) No. 2018-13 Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The update removes, modifies and makes additions to the disclosure requirements on fair value measurements. The update was adopted as of January 1, 2020, and its adoption did not have a material impact on the Company’s consolidated financial statements.

Accounting Standards Updates to Become Effective in Future Periods

In December 2019, the FASB issued 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 is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. Management is evaluating the impact of this update on the Company’s consolidated financial statements.

In August 2020, the FASB issued ASU No. 2019-12 Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The update is to address issues identified as a result of the complexity associated with applying generally accepted accounting principles for certain financial instruments with characteristics of liabilities and equity. The update is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years and with early adoption permitted. Management is evaluating the impact of this update on the Company’s consolidated financial statements.

The Company factors designated trade receivables pursuant to a factoring agreement with LSC Funding Group L.C., an unrelated factor (the “Factor”).  The agreement is for a term of one year with automatic renewal for additional one-year terms. The agreement specifies that eligible trade receivables are factored with recourse. The performance of all obligations and payments to the factoring company was personally guaranteed by John C. Lawrence, the Company’s previous President and Chairman of the Board of Directors. The existing agreement will be addressed in 2021 to account for Mr. Lawrence’s death and that impact on the personal guarantee. Selected trade receivables are submitted to the Factor, and the Company receives 85% of the face value of the receivable by wire transfer. Upon payment by the customer, the remainder of the amount due is received from the Factor, less a one-time servicing fee of 2% for the receivables factored.  This servicing fee is recorded on the consolidated statement of operations in the period of sale to the Factor.  

Trade receivables assigned to the Factor are carried at the original invoice amount less an estimate made for doubtful accounts.  Under the terms of the recourse provision, the Company is required to reimburse the Factor, upon demand, for factored receivables that are not paid on time.  Accordingly, these receivables are accounted for as a secured financing arrangement and not as a sale of financial assets.  

Receivables, net of allowances, are presented as current assets and the amount potentially due to the Factor is included in current accrued liabilities.
