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 2017, 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 developed sources of antimony in Mexico but we are still depending on foreign companies for raw material in the future. We expect more raw materials from our own properties for 2018 and later years. We continue working with suppliers in North America, Central America, Europe, Australia, 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 that is ramping up for 2018, and (3) mining properties that include the Los Juarez mineral deposit with concessions in Queretaro, the Wadley mining concession in San Luis Potosi, the Soyatal deposits in Queretaro, and the Guadalupe properties in Zacatecas.

In our existing operations in Montana, we produce antimony oxide, sodium antimonate, 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. Sodium antimonate is primarily used as a fining agent (degasser) for glass in cathode ray tubes and as a flame retardant. 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 two of the three operating antimony smelters in North and Central America.

●

We are the sole 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
2017	1,891,439	$7,588,470	$4.01
2016	2,936,880	$8,744,170	$2.98
2015	2,487,321	$9,863,933	$3.97
2014	1,727,804	$8,132,410	$4.71
2013	1,579,182	$8,375,158	$5.30

Concentration of Sales:

During the two years ended December 31, 2017, the following sales were made to our three largest customers:

Sales to	For the Year Ended
Largest Customers	December 31, 2017	December 31, 2016
Mexichem Specialty Compounds Inc.	$3,335,046	$2,108,998
East Penn Manufacturing Inc	512,621	1,147,854
Kohler Corporation	1,928,962	1,474,854
	$5,776,629	$4,731,706
% of Total Revenues	56.50%	39.80%

While the loss of one of our three largest customers would be a problem in the short term, we have numerous requests from potential buyers that we cannot fill, and we could quickly, in the present market conditions, be able to replace the lost sales. Loss of all three of our largest customers would be more serious and may affect our profitability.

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

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 price range of prices for antimony oxide and antimony metal, per pound, was as follows:

	USAC SALES
	Oxide	Metal	Combined	USA	Rotterdam
			(Metal Contained Price)
	Average	Average	Average	Average	Average
Year	Price/Lb	Price/Lb	Price/Lb	Price/Lb	Price/Lb
2017	$3.40	$3.41	$4.01	$3.77	$3.78
2016	$3.11	$2.62	$2.98	$2.99	$2.94
2015	$3.34	$3.71	$3.97	$3.41	$3.32
2014	$4.00	$4.18	$4.71	$4.40	$4.31
2013	$4.41	$4.69	$5.30	$4.73	$4.78

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. A company controlled by the estate of Al Dugan, a significant stockholder and, as such, an affiliate of USAC, receives a payment equal to 3% of net sales on 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%. BRZ has constructed a processing plant on the property and it has improved its productive capacity. In addition to a large amount of fully depreciated equipment that has been transferred from the USAC division, we have spent approximately $3,945,000 to purchase and construct the processing plant as of December 31, 2017.

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.

●

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 and animal waste treatment facilities.

●

Animal Nutrition. Feeding up to 2% zeolite increases growth rates, decreases conversion rates, prevents scours, and increases longevity.

●

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, 2017 and 2016, 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, 2017.

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, 2017. 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, 2017, we employed 27 full-time employees in Montana. In addition, we employed 16 people at our zeolite plant in Idaho, and more than 60 employees at our mining, milling and smelting operation in Mexico. The number of full-time employees may vary seasonally. None of our employees are covered by any collective bargaining agreement.

Other

We hold no material patents, licenses, franchises or concessions. However, we consider our antimony processing plants proprietary in nature.

We are subject to the requirements of the Federal Mining Safety and Health Act of 1977, the Occupational Safety and Health Administration's regulations, requirements of the state of Montana and the state of Idaho, federal and state health and safety statutes and Sanders County, Montana and Franklin County, Idaho health ordinances.

Item 1A Risk Factors

There may be events in the future that we are not able to accurately predict or over which we have no control. The risk factors listed below, as well as any cautionary language in this report, provide examples of risks, uncertainties and events that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements.

If we were liquidated, our common stockholders could lose part, or all, of their investment.

In the event of our dissolution, the proceeds, if any, realized from the liquidation of our assets will be distributed to our stockholders only after the satisfaction of the claims of our creditors and preferred stockholders. The ability of a purchaser of shares to recover all, or any portion, of the purchase price for the shares, in that event, will depend on the amount of funds realized and the claims to be satisfied by those funds.

We may have 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 projects 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.

We have accruals for asset retirement obligations and environmental obligations.

We have accruals totaling $271,572 on our balance sheet at December 31, 2017, 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.

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).

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 law suits. 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.	San Miguel I and II were purchased by a USAC subsidiary, Antimonio de Mexico, S. A. de C. V (AM), for $1,480,500. As of December 31, 2017, we have paid for the property, and have incurred significant permitting costs. The property consists of 40 hectares.
2.	San Juan I and II are concessions owned by AM and include 466 hectares.
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.

The concessions collectively constitute 720 hectares. 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.

The mineralized zone is a classic jasperoid-type deposit in the Cretaceous El Doctor Limestone. The mineralization is confined to silicified jasperiod 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.

Soyatal Mining District, Pinal De Amoles, Queretaro, Mexico

Soyatal

Reportedly, the Soyatal District was the third largest producer of antimony in Mexico. U. S. Geological Survey Bulletin 960-B, 1948, Donald E. White, Antimony Deposits of Soyatal District, State of Queretaro, Mexico records the production from 1905-1943 at 25,600 tons of antimony metal content. In 1942, the mines produced ore containing 1,737 tons of metal, and in 1943, they produced ore containing 1,864 tons of metal. This mining was performed primarily all by hand labor, with no compressors or trammers, and the ore was transported by mules, in sacks, to the railroad. Recoveries were less than 40% of the values. Mining continued throughout World War II.

Mr. White remarks p. 84 and 85, “In the Soyatal Mines, as in practically all antimony mines, it is difficult to estimate the reserves, for the following reasons:

●

The individual deposits are so extremely irregular in size, shape, and grade that the amount of ore in any one of them is unknown until the ore has been mined.

●

As only the relatively high grade shipping ore is recovered, the ore bodies are not systematically sampled and assayed…The total reserves are thus unknown and cannot be estimated accurately, but they probably would suffice to maintain a moderate degree of activity in the district for at least 10 years. The mines may even contain enough ore (mineralized deposit) to equal the total past production.”

Minimal ore, primarily through hand mining and sorting methods, has continued at the Soyatal properties since 1943. We do not claim any reserves at Soyatal as defined by the SEC.

USAMSA Puerto Blanco Flotation Mill, Guanajuato, Mexico

The flotation plant has a capacity of 140 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, Guadalupe, and other properties. We are in the process of installing a 400 metric ton per day flotation mill that will be dedicated to processing ore from our Los Juarez property. The crushing equipment currently in place is adequate for both flotation mills. An oxide circuit was added to the plant in 2013 and 2014 to mill oxide ores from Soyatal 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 are presently installing a cyanide leach circuit and settling pond that will be used to recover precious metals from our Los Juarez mine. During 2017 and 2016, less than 10% of the mill’s capacity was utilized.

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. Seventeen small rotating furnaces (SRF’s) and one large rotating furnace (LRF) with an associated stack and scrubber were permitted and installed by the end of 2015. 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 five to six metric tons of direct shipping ore or concentrates per day, depending on the quality of the feedstock. If the feedstock is in the mid-range of 45% antimony, the smelter could produce approximately 1.8 MM pounds of contained antimony annually. Concentrates from our flotation plant, and hand-sorted ore from Mexico sources and other areas, are being processed. During 2017, 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 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 and 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 were 20 to 30 foot, 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 multivibe 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.

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, 2017, we incurred a loss of $1,134,394 for 2017 after depreciation and amortization of $968,888, compared to a loss of $1,309,200 for 2016 after depreciation and amortization of $999,737, and an income tax provision of $298,138 for our Mexican operations. Our company-wide EBITDA was a negative $165,506 for 2017, compared to a negative $11,325 for 2016.

Net non-cash expense items totaled $1,275,000 for 2017 and included $968,888 for depreciation and amortization, $93,450 for amortization of debt discount, $175,000 for director compensation and $37,662 for other items.

Net non-cash expense items totaled $1,176,608 for 2016 and included $999,737 for depreciation and amortization, $70,590 for amortization of debt discount, $54,000 for stock-based compensation, $168,750 for director compensation and ($116,469) for other items.

Antimony Sales

During 2017, we saw our average sale price increase by $1.03 per pound to $4.01 per pound from an average price of $2.98 per pound for 2016. Due to the loss of our supply of antimony concentrates from Australia, the volume of antimony sold (metal contained) decreased from a record of 2,936,880 pounds sold in 2016 to 1,891,439 pounds sold in 2017, a decrease of 1,045,441pounds. During 2017 our production and sales from Mexican sources was approximately 530,000 pounds from our mines, and approximately 35,000 pounds from Australian concentrates. During 2017, the loss of raw material from Australia saw our gross sales of antimony decrease by $1,155,700 (13%). The antimony division had a negative EBIDTA of $1,094,579 for 2017, compared to a negative EBITDA of $1,131,971 for 2016. Our loss from antimony decreased from a loss of $2,171,611 in 2016 to a loss of $1,776,239 in 2017.

In November of 2017, we renegotiated our sodium antimonite supply agreement 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 December of 2017, and will result in lower antimony production costs and an improved cash flow for 2018 and the following years.

Zeolite Sales

Our sales volume of zeolite in 2017 was 766 tons less than we sold in 2016, a decrease of 6%. Our average sales price decreased by approximately $5 per ton, from $188 per ton in 2016 per ton to $183 per ton in 2017 (3%). During 2017, total sales of zeolite decreased by $206,458 from 2016. The zeolite division had EBIDTA of $554,201 for 2017, compared to EBITDA of $447,775 for 2016. Net income increased from $233,907 in 2016 to $331,472 in 2017, approximately $98,000.

During the two year period ended December 31, 2017, the most significant events affecting our financial performance were the fluctuation of antimony prices and the decrease in our sources of antimony raw material. During the first half of 2016, the price for antimony hit a seven year low, but recovered to approximately $4.00 per pound by the end of 2017. By the end of 2016, we stopped the processing of antimony concentrate for Hillgrove Mines, Ltd., of Australia and started production from our own mines in Mexico. There was no production from our own mines in Mexico, during 2016 due to the processing of concentrates from Hillgrove. We produced approximately 530,000 pounds from our Mexican properties in 2017. The Puerto Blanco mill circuits were utilized less than 10% of their capacity. Going forward, the increased supply of raw material from Mexico and the metal prices for both antimony and precious metals will be the most significant factors influencing our operations. Included in antimony cost of sales-Mexico are costs of approximately $276,000 and $358,000 for 2017 and 2016, respectively, relating to maintaining our mineral properties which were idle for 2016 and for a portion of 2017.

The following are highlights of the significant changes during 2017 and the two year period then ended:

Antimony:

●

The sale of antimony during 2017 was 1,891,439 pounds compared to 2,936,880 pounds in 2016, a decrease of 1,045,441 pounds (36%).

●

The average sales price of antimony during 2016 was $2.98 per pound compared to $4.01 during 2017, an increase of $1.03 per pound (35%). During the beginning of 2018, the Rotterdam price of antimony is approximately $3.75 per pound.

●

The metallurgical problem with the Los Juarez concentrates has been solved with cyanide and caustic leach plants, and pilot mining, milling, and smelting will resume. This will put the Puerto Blanco mill in operation during 2018. During 2017 and 2016, the Puerto Blanco mill was operating at less than 10% of capacity.

●

The net loss per pound of antimony was $0.94 in 2017 even though the price increased $1.03 per pound from 2016. The net loss per pound in 2016 was $0.74 per pound.

●

Our cost of goods sold for antimony decreased from $9,168,697 in 2016 to $8,145,846 in 2017. This was primarily due to the decrease in raw material from Australia. For the years ended December 31, 2017 and 2016, costs of goods sold include operating and non-operating production costs from Mexico operations.

●

Our cost of production for the years ended December 31, 2017 and 2016 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 concentrates from Australia in 2016. Production from Madero during 2017 was primarily from our own Mexican properties, and we purchased a significant portion of the raw materials for our smelter in Montana.

●

We are proceeding with the testing of the Los Juarez ore in the 100 ton per day mill at Puerto Blanco. A 400 ton per day flotation mill is permitted and is partially installed. This mill will be dedicated to processing rock from the Los Juarez mining property. We have adequate crushing capacity in place to feed the 450 ton per day mill and the existing mill.

●

Our principal smelter, precious metals recovery operation, and our Company headquarters remain in Montana.

Zeolite:

During 2017, BRZ sold 12,377 tons compared to 13,143 tons in 2016, down 766 tons (6%). BRZ realized a net income of $331,472 in 2017 after depreciation of $222,729 compared to a net income of $233,907 in 2016 after depreciation of $213,868. Production efficiency at the plant in Preston, Idaho, increased in 2017 due to repairs and new equipment. Sales activity in the early part of 2018 includes a number of new customers.

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 5.2%, and 5.7%, of sales for 2017 and 2016, respectively.

The decrease in professional fees for 2017 (approximately $91,000) was primarily due to attorney fees of approximately $72,000 paid in 2016 related to our former Investor Relations representative. Our accounting fees for 2017 related to our annual audit and our quarterly SEC filings decreased by approximately $15,000 from the prior year.

Factoring costs increased in 2017 from approximately $35,000 in 2016 to approximately $36,000 in 2017.

The discounts we gave for early payments were approximately $110,000 for both 2017and 2016.

Subsidiaries

The Company has a 100% investment in two subsidiaries in Mexico, USAMSA and AM, whose mineral property carrying values were assessed at December 31, 2017 and 2016 for impairment. Management’s assessment of the subsidiaries’ fair value was based on their future benefit to us.

Financial Condition and Liquidity

	2017	2016
Current assets	$1,562,270	$1,692,555
Current liabilities	(3,934,726)	(3,382,123)

Checks issued and payable	(7,434)	35,682
Net change in cash	$17,930	$(123,486)

Our net working capital decreased for the year ended December 31, 2017, from a negative amount of $1,689,568 at the beginning of the year to a negative amount of $2,372,456 at the end of 2017. Our current assets decreased primarily due to a decrease in our accounts receivable, which was partially offset by an increase in our inventories. Our current liabilities increased by approximately $550,000 primarily due to an increase in our accounts payable and the current portion of long-term debt, which were partially offset by the decrease in our liability for factored accounts receivable. Capital improvements were paid for with cash and debt.

For the year ending December 31, 2018, we are planning to finance our improvements with operating cash flow. Our 2018 improvements are expected to include improvements related to completing the cyanide leach circuit at Puerto Blanco.

The current portion of our long term debt is serviceable from the cash generated by operations.

Going Concern Consideration

At December 31, 2017, the Company’s financial statements show negative working capital of approximately $2.4 million and an accumulated deficit of approximately $26.5 million. In addition, the Company has incurred losses for the prior three years. These factors indicate that there may be doubt regarding the ability to continue as a going concern for the next twelve months.

The continuing losses are principally a result of the Company’s antimony operations and in particular to the production costs incurred in Mexico. The other two operating divisions, precious metals and zeolite, had gross profits of $310,373 and $408,403, respectively, in 2017.

Regarding the antimony division, in 2016 the Company endured some of the lowest prices for antimony in the past seven years, with an average sales price of only $2.98 per pound of metal contained. Prices improved during 2017 with an average sale price of $4.01. Through March 2018, our average sale price for antimony is approximately $4.10 per pound. Additionally, in November 2017, the Company renegotiated its domestic sodium antimonite supply agreement resulting in a lower cost for antimony per pound of approximately $0.44. With the new supply agreement in place, most of the market increase in antimony prices will result in increased Company cash flow in 2018 from its antimony division.

In 2017, the Company reduced costs for labor at the Mexico locations which has resulted in a lower overall production costs in Mexico which will continue through 2018. The reduction was due to a large reduction in the work force at the Madero smelter because of the decrease in antimony concentrates from Hillgrove (see Note 10). In the fourth quarter 2017, the Company also adjusted operating approaches at Madero that will likely result in a decrease in operating costs for fuel, natural gas, electricity, and reagents. Although total production activity in Mexico decreased in 2017 due to the lack of Hillgrove concentrates, the Company’s 2018 plan involves ramping up production at its own antimony properties in Mexico. In addition, a new leach circuit expected to come on line during 2018 in Mexico will result in more extraction of precious metals.

In 2017, management implemented wage and other cost reductions at the corporate level that will keep administrative costs stable in 2018. The Company expects to continue paying a low cost for propane in Montana, which in years past has been a major operating cost.

Over the past several years, the Company has been able to make required principal payments on its debt from cash generated from operations without the need for additional borrowings or selling shares of its common stock. The Company plans to continue keeping current on its debt payments in 2018 through cash flows from operations.

Management believes that the current circumstances and cost reduction actions taken will enable the Company to be actively operating for the next twelve months.

Critical Accounting Estimates

We have, besides our estimates of the amount of depreciation on our assets, two critical accounting estimates. The value of our unprocessed ore in inventory is assessed on assays taken at the time the ore is delivered, and may vary when the ore is processed and final settlement is made. 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 in our inventory at the Wadley mining concession and Puerto Blanco mill is based on assays taken at the time the ore is delivered, and may vary when the ore is processed and final settlement is made. 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 and accounts payable amounts, but would not change our reported cost of goods sold or net income amounts. At December 31, 2017, if we had overestimated the per cent of antimony in our total inventory of purchased ore by 2.5%, (a 10% correction to the amount of antimony metal contained if we assayed 25.0% antimony per metric ton), the amount of our inventory and accounts payable would be smaller by approximately $1,500. 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 (by $13,490 for 2017 and $12,155 for 2016). 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 Financial Officer of the effectiveness of the design and operations of our disclosure controls and procedures (as defined in Rule 13a – 15(e) and Rule 15d – 15(e) under the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, the Principal Executive Officer and the Principal Financial Officer have concluded that our disclosure controls and procedures were not effective in ensuring that: (i) information required to be disclosed by the Company in reports that it files or submits to the Securities and Exchange Commission under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in applicable rules and forms and (ii) material information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow for accurate and timely decisions regarding required disclosure.

Disclosure controls and procedures were not effective due primarily to material weaknesses in the Company’s internal control of financial reporting as discussed below.

Internal control over financial reporting

Management's annual report on internal control over financial reporting

The management of USAC is responsible for establishing and maintaining adequate internal control over financial reporting. This internal control system has been designed to provide reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of our published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The management of USAC has assessed the effectiveness of our internal control over financial reporting as of December 31, 2017. 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, 2017. These weaknesses are as follows:

●

Inadequate design of internal control over the preparation of the financial statements and financial reporting processes;

●

Inadequate monitoring of internal controls over significant accounts and processes including controls associated with domestic and Mexican subsidiary operations and the period-end financial reporting process; and

●

The absence of proper segregation of duties within significant processes and ineffective controls over management oversight, including antifraud programs and controls.

We are aware of these material weaknesses and will develop procedures to ensure that independent review of material transactions is performed. The chief financial officer will develop internal control measures to mitigate the lack of 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.

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, 2017, 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, 2017.

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 and Subsidiaries (the "Company") as of December 31, 2017 and 2016, the related consolidated statements of operations, changes in stockholders’ equity and cash flows for 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, 2017 and 2016, and the results of its operations and its cash flows for 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, anaudit 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.

DeCoria, Maichel & Teague, P.S.

We have served as the Company's independent auditor since 1998.

Notes to Consolidated Financial Statements

December 31, 2017 and 2016

1. 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.

2. Concentrations of Risk

The Company’s financial instruments that were exposed to concentrations consist primarily of sales and accounts receivable.

The Company's revenues from antimony sales are strongly influenced by world prices for such commodities, which fluctuate and are affected by numerous factors beyond the Company's control, including inflation and worldwide forces of supply and demand. The aggregate effect of these factors is not possible to predict accurately.

3. Summary of Significant Accounting Policies

Principles of Consolidation

The Company's consolidated financial statements include the accounts of BRZ, USAMSA and AM, all wholly-owned subsidiaries. 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, 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, 2017 and 2016 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, 2017 and 2016 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 our operations. Foreign translation gains and losses relating to our Mexican subsidiaries are recognized as foreign exchange gain or loss in our consolidated statement of operations.

3. Summary of Significant Accounting Policies, continued:

Going Concern Consideration

At December 31, 2017, the Company’s financial statements show negative working capital of approximately $2.4 million and accumulated deficit of approximately $26.5 million. In addition, the Company has incurred losses for the prior three years. These factors indicate that there may be doubt regarding the ability to continue as a going concern for the next twelve months.

Regarding the antimony division, in 2016 the Company endured some of the lowest prices for antimony in the past seven years, with an average sales price of only $2.98 per pound of metal contained. Prices improved during 2017 with an average sale price of $4.01. Through March 2018, the average sale price for antimony is approximately $4.10 per pound. Additionally in November 2017, the Company renegotiated its domestic sodium antimonite supply agreement resulting in a lower cost per antimony per pound of approximately $0.44. With the new supply agreement in place, most of the market increase in antimony prices will result in increased Company cash flow in 2018 from its antimony division.

In 2017, the Company reduced costs for labor at the Mexico locations which has resulted in a lower overall production costs in Mexico which will continue through 2018. The reduction was due to a large reduction in the work force at the Madero smelter because of the decrease in antimony concentrate from Hillgrove (see Note 10). In the fourth quarter 2017, the Company also adjusted operating approaches at Madero that will likely result in a decrease in operating costs for fuel, natural gas, electricity, and reagents. Although total production activity in Mexico decreased in 2017 due to the lack of Hillgrove concentrates, the Company’s 2018 plan involves ramping up production at its own antimony properties in Mexico. In addition, a new leach circuit expected to come on line during 2018 in Mexico will result in more extraction of precious metals.

Management believes that the current circumstances and cost reduction actions taken will enable the Company to be actively operating for the next twelve months.

Mineral Rights

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. No impairment has been indicated for the years ended December 31, 2017 or 2016 as a result of this assessment. Mineral rights are subject to write down in the period the property is abandoned.

3. Summary of Significant Accounting Policies, continued:

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. The Company capitalized $405,819 and $665,370 in plant construction and other capital costs for the years ended December 31, 2017 and 2016, respectively. These amounts include capitalized interest of $0 and $35,305, respectively. 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.

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.

Management of the Company periodically reviews the net carrying value of all of its long-lived assets. These reviews consider the net realizable value of each asset or group to determine whether a permanent impairment in value has occurred and the need for any asset write-down. An impairment loss is recognized when the estimated future cash flows (undiscounted and without interest) expected to result from the use of an asset are less than the carrying amount of the asset. Measurement of an impairment loss is based on the estimated fair value of the asset if the asset is expected to be held and used.

Exploration and Development

The Company records exploration costs as operating expenses in the period they occur, and capitalizes development costs on discrete mineralized bodies that have proven reserves in compliance with Securities and Exchange Commission Industry Guide 7, and are in development or production.

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

Sales of antimony and zeolite products are recorded either upon shipment or delivery dependent on the term, and when title passes to the customer. The Company's sales agreements do not provide for product returns or allowances. Prepayments, which are not common, received from customers prior to the time that products are processed and shipped, are recorded as deferred revenue. When the related products are shipped, the amount recorded as deferred revenue is recognized as revenue.

Sales of precious metals are recognized when pervasive evidence of an arrangement exists, the price is reasonably determinable, the product has been delivered, no obligations remain, and collection is reasonably assured.

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 consideration received or the fair value of the common stock issued, whichever is more readily determinable.

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. Management has determined that the calculation of diluted earnings per share for the years ended December 31, 2017, and 2016, does not add any shares to basic weighted average shares.

As of December 31, 2017 and 2016, potentially dilutive common stock equivalents not included in the calculation of diluted earnings per share are as follows:

	December 31, 2017	December 31, 2016
Warrants	250,000	250,000
Convertible preferred stock	1,751,005	1,751,005
Total possible dilution	2,001,005	2,001,005

Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, certificates of deposits, restricted cash, due to factor, and long-term debt. 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.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09 Revenue Recognition, replacing guidance currently codified in Subtopic 605-10 Revenue Recognition-Overall with various SEC Staff Accounting Bulletins providing interpretive guidance. The new ASU establishes a new five step principles-based framework in an effort to significantly enhance comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets. In August 2015, the FASB issued ASU No. 2015-14 Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. ASU No. 2015-14 defers the effective date of ASU No. 2014-09 until annual and interim reporting periods beginning after December 15, 2017. The Company has performed an assessment of the impact of implementation of ASU No. 2014-09, and concluded it will not change the timing of revenue recognition or amounts of revenue recognized compared to how revenue is recognized under current policies. ASU No. 2014-09 will require additional disclosures, where applicable, on (i) contracts with customers, (ii) significant judgments and changes in judgments in determining the timing of satisfaction of performance obligations and the transaction price, and (iii) assets recognized for costs to obtain or fulfill contracts.

In February 2016, the FASB issued ASU No. 2016-02 Leases (Topic 842). The update modifies the classification criteria and requires lessees to recognize the assets and liabilities on the balance sheet for most leases. The update is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the potential impact of implementing this update on the consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15 Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update provides guidance on classification for cash receipts and payments related to eight specific issues. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of implementing this update on the consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18 Statement of Cash Flows (Topic 230): Restricted Cash. The update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The Company does not expect this update to have a material impact on the consolidation financial statements.

3. Summary of Significant Accounting Policies, continued:

In January 2017, the FASB issued ASU No. 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business. The update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company will apply the provisions of the update to potential future acquisitions occurring after the effective date.

Other accounting standards that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption.

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.

4. 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 is personally guaranteed by John C. Lawrence, the Company’s President and Chairman of the Board of Directors. 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 presented as a secured financing in current liabilities.

Accounts Receivble	December 31, 2017	December 31, 2016
Accounts receivable - non-factored	$351,699	$401,720
Accounts receivable - factored with recourse	10,880	150,399
Accounts receivable - net	$362,579	$552,119

Factoring fees paid by the Company during the years ended December 31, 2017 and 2016, were $35,993 and $35,182, respectively. For the years ended December 31, 2017 and 2016, net accounts receivable of approximately $1.70 million and $1.80 million, respectively, were sold under the agreement.

Proceeds from the sales were used to fund inventory purchases and operating expenses.

10. 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) by which Hillgrove advanced the Company funds to be used to expand its smelter in Madero, Mexico, and in Thompson Falls, Montana, so that they may process antimony and gold concentrates produced by Hillgrove’s mine in Australia. The agreement required that the Company construct equipment so that it can process approximately 200 metric tons of concentrate initially shipped by Hillgrove. The parties agreed that the equipment will be owned by the Company. The agreement called for the Company to sell the final product for Hillgrove, and Hillgrove to have approval rights of the customers for their products. The agreement allows the Company to recover its operating costs at a rate approved by Hillgrove, and to charge a 7.5% processing fee and a 2.0% sales commission on each sale. The initial term of the agreement is five years; however, Hillgrove may suspend or terminate the agreement at its discretion. The Company may terminate the agreement and begin using the furnaces for their own production if Hillgrove fails to recommence shipments within 365 days of a suspension notice.

The terms of the agreement require payment of the advance upon Hillgrove’s issuance of a stop notice. Under terms of the agreement, if a stop order is issued after two years, the repayment obligation is 81.25% of the funds advanced at that point. As no stop notice was issued during the initial two year period ended November 7, 2016, the Company’s obligation to Hillgrove is 81.25% of total advanced funds. Through December 31, 2016, Hillgrove advanced the Company a total of $1,396,721, resulting in a net liability of $1,134,221 which is 81.25% of monies advanced. No funds were advanced in 2017. Based on conversations with Hillgrove, management does not anticipate receiving a stop notice in 2018 thus the entire amount is classified as long term.

Series D

During 2002, the Board established a Series D preferred stock, authorizing the issuance of up to 2,500,000 shares. The Series D preferred stock has preference over the Company’s common stock but is subordinate to the liquidation preferences of the holders of the Company’s outstanding Series A, Series B and Series C preferred stock. Series D preferred stock carries voting rights and is entitled to annual dividends of $0.0235 per share. The dividends are cumulative and payable after payment and satisfaction of the Series A, B and C preferred stock dividends. No dividends have been declared or paid with respect to the Series D preferred stock. At December 31, 2017 and 2016, the cumulative dividends in arrears on the 1,751,005 outstanding Series D shares were $583,812 and $542,664, respectively, payable if and when declared by the Board of Directors.

The majority of Series D preferred shares are held by John Lawrence, president of the Company.

12. 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, 2017 and 2016, 300,000 shares of the Company's common stock had been previously issued under the Plan. There were no issuances under the Plan during 2017 and 2016.

In addition, the Company has Montana state net operating loss carry forwards of approximately $3.5 million which expire between 2017 and 2024, and Idaho state net operating loss carry forwards of approximately $1.5 million, which expire between 2032 and 2038. The Company has approximately $5.1 million of Mexican net operating loss carry forwards which expire between 2023 and 2027.

At December 31, 2017 and 2016, 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, 2017 and 2016.

On December 22, 2017, the United States enacted the Tax Cuts and Jobs Act (the "Act") resulting in significant modifications to existing law. The Company completed the accounting for the effects of the Act during the quarter ended December 31, 2017. The Company did not incur any income tax benefit or provision for the year ended December 31, 2017 as a result of the changes to tax laws and tax rates under the Act. The Company’s net deferred tax asset was reduced by approximately $7,000 during the year ended December 31, 2017, which consisted primarily of the re-measurement of federal deferred tax assets and liabilities from 35% to 21%.

During the years ended December 31, 2017 and 2016, 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 2015 through 2017, and 2014 through 2017 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 Mexican pesos, which was approximately $666,400 in U.S. Dollars (“USD”) as of December 31, 2016. Approximately $285,000 USD of the total assessment is interest and penalties. SAT’s assessment is based on the disallowance of specific costs that the Company deducted on the 2013 USAMSA income tax return. These disallowed costs were incurred by the Company for USAMSA’s business operations. SAT claims that the costs were not deductible or were not supported by appropriate documentation. At December 31, 2017, the assessed amount is approximately $699,000 in U.S dollars.

13. Income Taxes, Continued:

Management has reviewed the assessment notice from SAT and believes numerous findings have no merit. The Company has engaged accountants and tax attorneys in Mexico to defend its position.

At December 31, 2016, management has estimated possible outcomes for this assessment and concluded the Company will ultimately pay an amount ranging from 30% to 100% of the total assessment. The 30% is based on the Company’s agreement with the tax professionals that the professionals will receive 30% of the amount of tax relief they are able to achieve. At December 31, 2016, the Company accrued a potential liability of $410,510 USD of which $285,048 was for unpaid income taxes, $75,510 was for interest expense, and $49,952 was for penalties. The amount accrued represented management’s best estimate of the amount that will ultimately be paid. The outcome could vary from this estimate.

During 2017, the Company filed grievance and legal arguments regarding the SAT audit and presented arguments to the court in September 2017. The Company is waiting for the court’s ruling on the matter and expects resolution in 2018. Based on this status, the Company concluded that the estimate of potential assessment determined at December 31, 2016 remains the most likely outcome at December 31, 2017. The December 31, 2016 income tax payable due of $410,510 was increased by $32,600 due to the change in exchange rate between the U.S. dollar and Mexican peso. Fluctuation in exchange rates will have an ongoing impact on the amount the Company will pay in U.S. dollars.

If an issue addressed during the SAT audit is resolved in a manner inconsistent with management expectations, the Company will adjust its net operating loss carryforward, or accrue any additional penalties, interest, and tax associated with the audit. The Company’s tax professionals in Mexico have reviewed and filed tax returns with the SAT for 2014, 2015, and 2016, and have advised the Company that they do not expect the Company to have a tax liability for those years relating to similar issues.

14. Related-Party Transactions

15. Commitments and Contingencies

In 2005, Antimonio de Mexico, S. A. (“AM”) signed an option agreement that gives AM the exclusive right to explore and develop the San Miguel I and San Miguel II concessions for annual payments. Total payments will not exceed $1,430,344, reduced by taxes paid. During the year ended 2016 $65,000 was paid and capitalized as mineral rights in accordance with the Company’s accounting policies. At December 31, 2017 and 2016, the Company has made all of the required payments under the agreement.

In June of 2013, the Company entered into a lease to mine antimony ore from concessions located in the Wadley Mining district in Mexico. The lease calls for a mandatory term of one year and requires payments of $10,000 plus IVA tax of $1,600 per month. The lease is renewable each year with a 15 day notice to the lessor, and agreement of terms. The lease was renewed in June of 2017.

From time to time, the Company is assessed fines and penalties by the Mine Safety and Health Administration (“MSHA”). Using appropriate regulatory channels, management may contest these proposed assessments. At December 31, 2017 and 2016, the Company has no accruals relating to such assessments.

16. Business Segments

The Company is currently organized and managed by four segments, which represent the three operating units: United States antimony operations, Mexican antimony operations and United States zeolite operations, and a separate segment for revenue received from the sale of precious metals recovered from the antimony process. The Company’s precious metals segment was added as a new reporting segment in 2016. The precious metals activity has been reclassified from the antimony segment for 2017 and 2016. The Company’s Other operating costs include general and administrative expenses, freight and delivery, and other non-production related costs. Other income and expense consists primarily of interest income and expense and factoring expense.

The Madero smelter and Puerto Blanco mill at the Company’s Mexico operation brings antimony up to an intermediate stage, which is then shipped 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 revenues are from sales 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 2 and 6, respectively.
