CHAIRMAN’S LETTER
Dear Shareholders:
In 2015, we concluded a major addition to our smelting capacity at Madero, Mexico with the addition of a large furnace (LRF) and five smaller furnaces (SRFs) to process high grade concentrates. The additional smelting capacity enabled us to achieve record sales of antimony for the year. Most of the plant was dedicated to processing Australian concentrates, and we processed minimal raw material from our Mexican properties. The replacement of propane with natural gas at the Madero smelter is saving 75% of the cost of fuel. We also saw a major increase in zeolite sales for 2015, setting a record for tons of zeolite sold. During 2015, we perfected our method of recovering gold from antimony concentrates from Australia, and during the first quarter of 2016, we began selling gold to a refinery. This process will be applicable to the concentrates from the Los Juarez mining property. Our progress in production and sales was offset by a continued slide in the price of antimony which has continued since 2011. In 2015, we purchased the Guadalupe mining property that will produce a high-grade concentrate that can be sold to the friction brake industry or used to make ordnance. Both products will sell for premium prices. In the third quarter of 2015, Hillgrove and supply enough concentrates to Mines Pty Ltd, suspended mining operations in Australia. We were notified that they would continue milling operations keep the LRF running through the end of 2016. In addition, USAMSAS will be allowed to use the Hillgrove furnace capacity for USAC’s Mexican properties while Hillgrove explores for higher grade ore. We will ramp up production with smelter feed from Guadalupe, Wadley, Soyatal, and Los Juarez.
An all-time sales record for antimony of 2,487,321 pounds was achieved in 2015. The gross revenue from all sources of antimony for 2015 was $9,863,933, and the loss was $1,349,934, which included $711,345 of depreciation and amortization. The loss was primarily due to:

| ● | A drop in the price of antimony for the year of $0.75 per pound from $4.71 in 2014 to $3.96 in 2015.
| ● | Holding costs of $1,086,440 or $0.44per pound due to 1) solving a metallurgical issue which delayed production at our Los Juarez silver-antimony-gold property and its associated Puerto Blanco mill, and 2) fixed cost agreements for mining properties that are idle until we need more raw material.

An all-time sales record for zeolite of 15,901 tons was achieved in 2015. Even though the average price per ton decreased by approximately $22, we achieved record sales of $2,753,644. The net income for zeolite was $511,403, which was after $221,441 of depreciation.
Management has been working to increase production and reduce costs as follows:

1. | An all-out effort is being made to bring the Los Juarez gold-silver-antimony property into production. This includes the shake-down of the leach plant at Madero and detailed flotation testing to determine whether a cyanide circuit is necessary. A shallow reconnaissance drilling program indicates a global average grade of 0.057 ounces (1.432 grams) gold, 2.43 ounces (75.24 grams) silver per metric ton, and 0.343% antimony. The gross value is $125 per ton based on gold at $1,230 per ounce, silver at $15 per ounce, and antimony at $2.45 per pound. USAC claims no reserves at Los Juarez per SEC definitions, and the drilling does not comply with Canadian NI 43-101.

2. | We are focused on reducing the holding costs (“Mexico excess production costs”) for Los Juarez, Wadley, Soyatal, Guadalupe, and the Puerto Blanco mill, which included a write-down to market value of significant concentrates and direct shipping ore (DSO) mined in 2013 and 2014 at Wadley, Soyatal, and other properties. These costs are included in our production costs and have a severe impact on profitability. The Mexico excess non-production costs amounted to $0.98 per pound of antimony produced in Mexico in 2015 and $1.17 per pound in 2014. When considered for the total antimony production of the Company as a whole, they amounted to $0.44 per pound in 2015 and $0.40 per pound in 2014.

4

3. | The Mexican furnace capacity has been limited to the processing of Australian concentrates. Within 60 days, production from the Mexican properties will be resumed which will reduce the “Mexican excess production costs” and liquidate inventory.

4. | At the Wadley, the holding costs have been reduced $69,600 per year, the mine grade is being raised from a minimum of 25% to a minimum of 35%, and the purchase price of the ore has been adjusted to a significantly lower price indexed to Rotterdam. Wadley is expected to be the largest Mexican producer of antimony by the end of this year.

5. | The Soyatal property continues to produce 30% concentrates from legacy mine dumps that contain from 4.5 to 9% antimony. The dumps are substantial and will provide a low cost feed with no mining costs.

6. | The Guadalupe mine has been on care and maintenance, but production will resume in the second quarter.

Following is the outlook for 2016:

1. | We are planning to increase the 2016 production of antimony with feed from Canada, Australia, and Mexico.

2. | We hope to maintain this growth trajectory with returns from working down our Mexican concentrate inventories, the cash flow from increased antimony production, and the Bear River Zeolite profits.

3. | A metallurgical issue related to the Los Juarez silver-antimony-gold property was solved in late 2015 that will allow us to start processing the Los Juarez concentrates in 2016.

USAC is an international, vertically-integrated company that provides antimony and zeolite from the mine to end users around the world. The Company has significant sources of raw materials and has always been a reliable domestic and international supplier. Our mission is to dominate the domestic antimony market.
Sincerely, John Lawrence
CEO and Chairman

ANTIMONY MARKET
The United States used 23,600 metric tons (approximately 52,000,000 pounds) of antimony in 2015. Of this amount 35% went to metal products primarily storage batteries and ammunition: 35% went to non-metal products including rubber, glass, and ceramics; and 30% went into flame retardants. The domestic market for USAC antimony products remained strong even though global prices deteriorated in a weak economic environment. In 2013, the world-wide production was 163,000 metric tons or 359,353,516 pounds. The Chinese control more than 90% of the world supply, and pricing can be volatile. Pricing of the metal is generally based on the London Metal Exchange average price C.I.F. Rotterdam per metric ton (a metric ton contains 2,204.6 pounds). Antimony oxide contains 83.1% antimony metal and it is typically our preferred product due to its premium pricing.

2. | The “Mexican excess production costs” include (1) holding costs for Los Juarez, Wadley, Soyatal, Guadalupe, and the Puerto Blanco mill, and (2) the write-down of significant concentrates and direct shipping ore (DSO) mined in 2013 and 2014 at Wadley, Soyatal, and other properties. These costs are included in our production costs and have a very severe impact on profitability. In 2015, they added $1,086,440 to the costs of the production of antimony. These costs amounted to $.98 per pound of antimony production in Mexico.

WADLEY MINE AND MILL, SAN LUIS POTOSI, MEXICO
The Wadley produced more than 80% of the Madero smelter feed during 2014. During that time, and through 2015, reconfiguration and testing of the gravity mill has proceeded. Mining is by hand methods without the benefit of compressed air and explosives. At one time, Wadley was shipping up to 600 tons per month of hand sorted ore to Laredo, Texas, which amounted to approximately 5,000,000 pounds per year of antimony. For 2016, we have reduced our lease costs for Wadley by approximately $70,000 from 2015, and raised the mine grade from a minimum of 25% to a minimum of 35%. We adjusted the purchase price to a significantly lower price indexed to the Rotterdam price for antimony. Currently, the operation is in a care and maintenance mode until we need the ore at our Madero smelter, but we expect Wadley to be the largest producer of Mexican antimony for us by the end of 2016. Contract miners from about 100 to 120 men are available at the present time. With increased mechanization and explosives, this property could produce much more antimony for us than it has in the past. We do not claim any reserves at Wadley as defined by the SEC.
12

SOYATAL DISTRICT, QUERETARO, MEXICO
USAC owns the Soyatal District mines. During 2014 and 2015, Soyatal produced a small amount of DSO (direct shipping ore for the smelter) and concentrates from low grade and dumps. After sampling some of the extensive dumps, USAC has begun milling dumps in the 4.5 to 9% range with a recovery of almost 50% at our Puerto Blanco mill. We expect the property to become a substantial producer of low cost feed. We do not claim any reserves at Soyatal as defined by the SEC.
GUADALUPE, ZACETECAS, MEXICO
The Guadalupe mining property has been on care and maintenance, but production will resume in the second quarter of 2016. The ore from Guadalupe results in very high grade concentrate of approximately 65% to 70% antimony tri-sulfide that could be shipped to the friction-brake industry for a premium price. We do not claim any reserves at Guadalupe as defined by the SEC.
PUERTO BLANCO OXIDE/SULFIDE MILL, GUANAJUATO, MEXICO
In 2014, the Puerto Blanco mill processed 1,284 tons of sulfide ore from Guadalupe and 1,676 tons of oxide ore from Guadalupana and 458 tons of oxide ore from Soyatal. In 2015, the mill processed legacy dump material from our Soyatal property using the oxide circuit. This constituted less than 10% of the mill capacity. During 2015, the Puerto Blanco mill was primarily engaged in test runs of various ores to improve mineral recovery. CAPEX expenditures in 2015 were primarily the construction of the oxide circuit, the installation of cleaner flotation cells, the design and construction of a leach circuit, and limited work on the 500 ton mill. In the second half of 2016, the mill will primarily be engaged in processing ore from our Los Juarez mining property.
MADERO SMELTER, COAHUILA, MEXICO
The Madero smelter produces very high quality antimony from Mexico. The Madero smelter has 17 small furnaces (SRF’S) and one large furnace (LRF). The LRF and five of the SRF’s have been dedicated to processing concentrates from Australia during 2015. A natural gas pipeline has reduced our per pound Mexican fuel costs by about 75%. During 2015, we built and installed four SRF’s for our own use, five SRF’s and one LRF for the Hillgrove concentrate, a 100 foot stack for fume dispersion, and multiple improvements to our infrastructure. Hillgrove has notified us that they are not mining in Australia at this time, and that we should expect that we will not receive the same amount of concentrates for 2016 that we received in 2015. We are prepared to increase our production from our Mexican mining properties to keep the Madero smelter producing near capacity. We are presently installing a leach plant at Madero to improve the recovery of precious metals from Los Juarez concentrates.
MONTANA SMELTER, THOMPSON FALLS, MONTANA
The Montana smelter at the USAC corporate headquarters in Thompson Falls, Mt., processes feed from Canadian, Mexican and Australian sources, recovers precious metals, and makes finished antimony oxide and metal. We have made substantial improvements to our precious metals recovery circuit at Thompson Falls in 2015.
HILLGROVE MINES, PTY. LTD. ARMIDALE, AUSTRALIA
USAC entered a purchase agreement with Hillgrove Mines Pty Ltd for 200 metric tons per month of 58% to 60% antimony concentrates that contain approximately 20 grams (0.64 ounces) of gold per metric ton. This amounts to approximately 3,000,000 pounds of antimony and 1,500 ounces of gold annually. Hillgrove provided funding to USAC to expand its smelter capacity in Mexico. In 2015, we processed 53 containers with approximately 1,084 metric tons of concentrate. We had approximately 20 containers on hand at the end of 2015, and we continue to receive containers at this time. Hillgrove has notified us that it has shut down mining in Australia, and that we will not receive concentrates once they have shipped what they have at their mill. We are recovering our processing costs, and we anticipate a 9.5% profit on sales.

PRECIOUS METALS OPERATIONS
LOS JUAREZ, QUERETARO, MEXICO
USAC has mapped and mined central parts of the mineralized zones of Los Juarez that appear to be vertical breccia pipes over a strike length of 3.5 kilometers with a maximum width of one kilometer. The mineralization is “open” on three sides and to depth.
After milling 3,500 metric tons of rock from the Mina Grande pit, the feed grade was determined to be approximately 0.789% antimony, 6.11 ounces of silver (189 grams), and 0.049 ounces of gold (1.52 grams) per metric ton.
A shallow but widespread drilling program was started in 2015 to identify the higher grade ore in the deposit. The global average based on these drill holes and rcok chip samples 0.057 ounces (1.77grams) gold, and 2.43 ounces (75.24 grams) silver, and 0.343% antimony per metric ton. To date, less than 5% of the property has been drilled. A leach plant was built at Madero during 2015 to treat flotation concentrates from Puerto Blanco. Following the successful operation of the 100 tons per day mill at Puerto Blanco and processing at Madero, an additional 500 ton per day mill will be completed and dedicated to Los Juarez ore at either Puerto Blanco or adjacent to the open pit at Los Juarez. We claim no reserves at Los Juarez as defined by the SEC, and the drilling does not comply with Canadian NI 43-101.
CANADIAN SOURCE
Precious metals will be recovered from an off-take agreement with a Canadian source and are sold back to the Canadian producer at a discount.
HILLGROVE MINES PTY. LTD.
Preparations are being made at our precious metal refinery in Montana to recover gold from Hillgrove concentrate. During the first quarter of 2016, we achieved a good recovery of precious metals from the Hillgrove concentrates, and have started delivery to a refinery. The process being used for the Hillgrove concentrates is transferable to the Los Juarez concentrates to be made at Puerto Blanco.
ZEOLITE OPERATIONS
During 2015, BRZ sales of $2,753,644 generated a profit of $511,403. Depreciation was $221,441, and the operation contributed $732,844 (EBITDA) to corporate growth. Following are the 2015 applications of BRZ:

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 under the symbol UAMY.
Overview
Antimony Sales
Although the volume of antimony sold (metal contained) increased 44% to 2,487,321 pounds in 2015 from 1,727,804 pounds in 2014, a decrease in the average sales price of antimony (metal contained basis) of approximately $0.75 per pound saw our gross sales of antimony increase by only $1,731,523 (21%). Our loss from antimony decreased from a loss of $1,926,126 in 2014 to a loss of $1,349,934 in 2015, a decrease of 30%. During 2015, the increase in sales of our antimony products (approximately 760,000 lbs) from 2014 was due to an increase in volume of raw material received from our Canadian supplier and from concentrates received from Hillgrove Mines of Australia. For our Mexican operations, we processed and sold approximately 907,000 pounds of antimony from Hillgrove Mines, and approximately 198,000 pounds from our Mexican properties. The raw material received from our Mexican properties decreased from approximately 586,000 lbs in 2014 to 198,000 pounds in 2015 because our furnace capacity was being used to process concentrates form Hillgrove.
Zeolite Sales
Our sales volume of zeolite in 2015 was 4,822 tons more than we sold in 2014, an increase of 44%. Our average sales price decreased by approximately $22 per ton, from $195.83 per ton to $173.17 per ton, a decrease of approximately 11%. The decrease in price was primarily due to sales of higher volume, lower priced products. During 2015, total sales of zeolite increased approximately $584,000 from 2014, and the profit increased from $330,671 in 2014 to $511,403 in 2015.

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 2015, 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 2016 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 that started expanded operations in late 2012, (2) the Puerto Blanco flotation mill and oxide circuit in Guanajuato that started operating on a test basis in late 2012 and is ramping up for 2016, and (3) mining properties that include the Los Juarez mineral deposit with concessions in Queretaro, the Wadley mining concessionin San Lis 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 polyethelene 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:
18

· | We have a reputation for quality products delivered on a timely basis.

· | We are a non-Chinese producer of antimony products.

· | 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 |
|  | Metal |  |  |  |  |  | Average |
Year |  | Contained |  |  | $ |  |  | Price/Lb |
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 |
2012 |  |  | 1,403,210 |  |  | $ | 8,753,449 |  |  | $ | 6.24 |
2011 |  |  | 1,401,423 |  |  | $ | 10,406,636 |  |  | $ | 7.43 |

Concentration of Sales:
During the two years ended December 31, 2015, the following sales were made to our three largest customers:

Sales to Three |  | For the Year Ended |
Largest Customers |  | December 31, 2015 |  |  | December 31, 2014 |
Alpha Gary Corporation |  | $ | 3,142,586 |  |  | $ | 3,289,766 |
East Penn Manufacturing Inc |  |  | 1,236,250 |  |  |  | 720,966 |
General Electric |  |  |  |  |  |  |  |
Kohler Corporation |  |  | 1,736,914 |  |  |  | 2,091,565 |
Polymer Products Inc. |  |  | - |  |  |  | - |
|  | $ | 6,115,750 |  |  | $ | 6,102,297 |
% of Total Revenues |  |  | 46.65 | % |  |  | 56.45 | %

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.

|  | USA |  |  | Rotterdam |
|  | Average |  |  | Average |
Year |  | Price/Lb |  |  | Price/Lb |
2015 |  | $ | 3.41 |  |  | $ | 3.32 |
2014 |  | $ | 4.40 |  |  | $ | 4.31 |
2013 |  | $ | 4.73 |  |  | $ | 4.78 |
2012 |  | $ | 5.86 |  |  | $ | 5.71 |
2011 |  | $ | 6.97 |  |  | $ | 7.05 |

19

A six year price range of our sales prices for antimony oxide and antimony metal, per pound, was as follows:

|  | Oxide |  |  | Metal |  |  | Combined |
|  | Average |  |  | Average |  |  | Average |
Year |  | Price/Lb |  |  | Price/Lb |  |  | Price/Lb |
2015 |  | $ | 3.34 |  |  | $ | 3.71 |  |  | $ | 3.97 |
2014 |  | $ | 4.00 |  |  | $ | 4.18 |  |  | $ | 4.71 |
2013 |  | $ | 4.41 |  |  | $ | 4.69 |  |  | $ | 5.30 |
2012 |  | $ | 5.14 |  |  | $ | 5.58 |  |  | $ | 6.24 |
2011 |  | $ | 6.16 |  |  | $ | 7.42 |  |  | $ | 7.43 |
2010 |  | $ | 3.67 |  |  | $ | 4.42 |  |  | $ | 4.34 |

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 and commercial 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 North America, Mexico, Europe, South America, Central America, and Australia.
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 $3,712,000 to purchase and construct the processing plant as of December 31, 2015.
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 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 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.

20

| · | 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 worms, 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, 2014 and 2015, 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 the our estimated costs of reclaiming, in accordance with regulatory requirements, the acreage disturbed by our zeolite operations remains unchanged at December 31, 2015.
21

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, 2015. 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, 2015, we employed 27 full-time employees in Montana. In addition, we employed 16 people at our zeolite plant in Idaho, and more than 40 employees at our mining, milling and smelting operation in Mexico. The number of full-time employees may vary seasonally. None of our employees are covered by any collective bargaining agreement.
Other
We hold no material patents, licenses, franchises or concessions, however we consider our antimony processing plants proprietary in nature.
We are subject to the requirements of the Federal Mining Safety and Health Act of 1977, the Occupational Safety and Health Administration's regulations, requirements of the state of Montana and the state of Idaho, federal and state health and safety statutes and Sanders County, Montana and Franklin County, Idaho health ordinances.
Item 1A Risk Factors
There may be events in the future that we are not able to accurately predict or over which we have no control. The risk factors listed below, as well as any cautionary language in this report, provide examples of risks, uncertainties and events that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements.
If we were liquidated, our common stockholders could lose part, or all, of their investment.
In the event of our dissolution, the proceeds, if any, realized from the liquidation of our assets will be distributed to our stockholders only after the satisfaction of the claims of our creditors and preferred stockholders. The ability of a purchaser of shares to recover all, or any portion, of the purchase price for the shares, in that event, will depend on the amount of funds realized and the claims to be satisfied by those funds.
We may have unasserted liabilities for environmental reclamation.
Our research, development, manufacturing and production processes involve the controlled use of hazardous materials, and we are subject to various environmental and occupational safety laws and regulations governing the use, manufacture, storage, handling, and disposal of hazardous materials and some waste products. The risk of accidental contamination or injury from hazardous materials cannot be completely eliminated. In the event of an accident, we could be held liable for any damages that result and any liability could exceed our financial resources. We also have one ongoing environmental reclamation and remediation 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.
22

We have accruals for asset retirement obligations and environmental obligations.
We have accruals totaling $260,327 on our balance sheet at December 31, 2015, 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 1B Unresolved Staff Comments
There are no unresolved staff comments from the Securities and Exchange Commission at December 31, 2015.
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 have been paying Sanders County property taxes on three patented mill site claims in the Burns Mining District of Montana since 1969 when we purchased the original block of claims. USAC was the registered owner of the claims at the Sanders County Courthouse. The claims include the Station Mill Site (4.994 acres), Excelsior Mill Site (4.972 acres), and the Mammoth Mill Site (5.000 acres) Patent Survey No. 9190A. We discovered that the BLM cancelled the patents on January 12, 2000, because “the claims were not filed with the BLM in accordance with the FLPMA and are deemed to be abandoned and void by operation of law.” Neither we, nor the Sanders County Court House, were ever notified of this decision, and we continue to pay taxes. Although we do not believe that this taking is valid, it does not have a substantial impact on us or our results of operations.
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.
23

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.
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 are being purchased by a USAC subsidiary, Antimonio de Mexico, S. A. de C. V (AM), for $1,480,500. To date, we have paid $1,415,500 on 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 in 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
On October 30, 2009, the Company entered into a supply agreement with the owners of the Soyatal concessions similar to that of Guadalupe. During the term of the supply agreement the Company funded certain of Soyatal’s equipment purchases, tax payments, labor costs, milling and trucking costs, and other expenses incurred in the Soyatal mining operations for approximately $140,000. In addition to the advances for mining costs, the Company purchased antimony ore from Soyatal that failed to meet agreed upon antimony metal recoveries and resulted in approximately $320,000 of excess advances paid to Soyatal. On April 4, 2012, the Company negotiated an option to purchase the Soyatal properties for $1,500,000, and made a deposit on the option of $55,000.
On August 5, 2013, the Company notified the owners of Soyatal that it was exercising the option to purchase the Soyatal property. The option exercise agreement allowed the Company to apply all amounts previously due the Company (the “Purchase Price Credits”) by Soyatal of $420,411 to the purchase price consideration. At December 31, 2013, the Company had Purchase Price Credits of approximately $325,000 which can be used as payments on the obligation at the rate of $100,000 per year until gone. The Company is obligated to make payments of $200,000 annually through 2020, and a final payment of $100,000 is due in 2021. The debt payable for the Soyatal mine is non-interest bearing. In 2013, the Company recorded the debt and the related Soyatal mine asset by determining the net present value of the contractual stream of payments due using a 6% discount rate. The resulting discount on the Soyatal debt was approximately $212,000 at December 31, 2013, and is netted against the debt payable resulting in a discounted amount of $762,541 at December 31, 2013. The discount is being amortized to interest expense using the effective interest method over the life of the debt.
During 2014 and 2015, $45,752 and $88,250 of the discount was amortized to the Soyatal debt, resulting in a discounted amount owed of $820,272 and a remaining debt discount of approximately $123,798 at December 31, 2015. The Company agreed to pay the Soyatal debt holder $100,000 during 2014 as part of the down payment agreement, and at December 31, 2015, this debt had been paid. The Company did not make the $100,000 payment due in January of 2015. The Company has been making payments of $5,000 per month that have been informally agreed to by the parties while the future payment terms of the Soyatal debt are negotiated. These payments have been recorded as reductions of long term debt.
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
During the fourth quarter of 2014, cleaner flotation machines were added the flotation mill at San Luis de la Paz (Puerto Blanco), Guanajuato, Mexico. All of the permits to construct and operate the plant have been obtained. 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 to 450 metric tons 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. 2014, less than 10% of the mill’s capacity was utilized. 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.
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 lbs of contained antimony annually. Concentrates from our flotation plant, and hand-sorted ore from Mexico sources and other areas, are being processed. The Madero production is shipped to our Montana plant to produce finished Antimony products and other derivative by-products. Access to the plant is by road and railroad.

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.
31

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 foot 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.

Excess Mexico production costs
During the two year period ending December 31, 2015, we incurred excess production costs at our Mexico operations. At the beginning of each year, management determined a standard, or expected, cost to produce antimony products for shipment to Montana for further processing. For 2015 and 2014, the standard costs per pound was $3.95 and $4.45, respectively. The production costs above the standard costs were calculated and reported in the above schedule of results of operations by division as “excess Mexico production costs”, which were $1,086,440 and $688,619 in 2015 and 2014, respectively. The excess Mexico production costs are primarily due to holding costs from inactivity at the Wadley and Los Juarez mines, the Puerto Blanco mill, and the loss of production at the Madero smelter from metalurgical testing and experimenting with various production methods and formulas.
Overview
Our cost of production was elevated for the years ended December 31, 2015 and 2014, because we were starting a major mining and production facility in Mexico. The same workers responsible for production were also a significant part of building and testing the manufacturing plants and equipment at Puerto Blanco and Madero, Mexico, which resulted in costs that won’t be incurred when construction and testing is complete. To a lesser degree, we incurred similar testing costs at our plant in Thompson Falls, Montana. In Mexico, there will still be some overlapping costs in 2016 because the smelter is finishing a major expansion in its physical plant. The production from Mexico should be greater for 2016 than 2015 once the plant expansion is complete and the management and crew at the Madero smelter can concentrate their efforts on production activities.
The non-cash expense items totaled $1,075,423 for 2015 and included $932,786 for depreciation and amortization, $5,137 for accretion, and $137,500 for director compensation.
The non-cash expense items totaled $903,392 for 2014 and included $780,782 for depreciation and amortization, $(2,390) for accretion, and $125,000 for director compensation.
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 a significant portion of our raw materials in 2014 and 2015. We will still purchase a significant portion of our raw materials from suppliers for our smelter in Montana.
We completed installation of a natural gas pipeline to replace propane as the fuel used in our Mexico smelter in the fourth quarter of 2014. We expected the pipeline to reduce our smelter fuel cost by approximately 75%. Our smelter fuel cost (propane) in Mexico was approximately $700,000 for 2013 and $690,000 using 8 furnaces for the first nine months of 2014, resulting in a cost of approximately $1.27 per pound. Our natural gas cost was $348,260 to produce 1,105,350 pounds of antimony in 2015, or approximately $0.32 per pound, a decrease of $0.95 per pound (74.8%).
We are proceeding with the installation of a 400 - 500 ton per day flotation mill that we expect to cost between $400,000 and $500,000 to install. The concrete work for the mill has been completed, and work will be ongoing as we generate cash from operations. This mill will be dedicated to processing ore from the Los Juarez mining property. We are in a waiting period for approval of permits necessary to process the Los Juarez ore. We have adequate crushing capacity in place to feed the 500 ton per day mill and the existing mill.
When approved, the restart of production from Los Juarez will create a significant increase in our precious metals revenue for 2016 and years forward.
Our principal smelter, precious metals recovery operation, and our Company headquarters remain in Montana. With increased production, we expect to widen our base of customers.

· | During the two year period ended December 31, 2015, the most significant event affecting our financial performance was the decrease in the price of antimony (see table page 6). During the year ended December 31, 2015, the most significant event was construction and start-up of a plant to process antimony concentrate for Hillgrove LTD of Australia. The expansion of production at our Mexico operations caused our reported operating costs to be elevated when compared to years when we were not initiating the start-up of new production facilities. The Mexican production of antimony (metal contained) and sold was 586,368 pounds during 2014 compared to 1,105,350 pounds for 2015, an increase of 88.5%. 2015 and 2014 are regarded as “start- up years” during which the holding costs, permitting, and metallurgical research was categorized as a “non-production” operating expense. During both years, Los Juarez concentrate was not produced and Soyatal oxide ore was in a research phase at the Puerto Blanco oxide circuit. Guadalupe was not in production for most of 2015while they prepared the underground for mining higher grade rock. 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. The following are highlights of the significant changes during 2015 and the two year period then ended:

a. | Our sales of antimony for 2015 increased by approximately 759,000 pounds (44%) from 2014. Our revenues from antimony increased in 2015 by approximately $1,712,000 (21%) from 2014 due to an increase in the amount of antimony sold. The average sale price for antimony contained in all products declined from $4.71 in 2014 to $3.96 per pound in 2015, a decrease of $0.75 (15.9%).

b. | The metallurgical problem with the Los Juarez feed has been solved, and mining, milling, and smelting will resume when the necessary permits are obtained. This will put the Puerto Blanco mill in operation. During 2015 and 2014, the Puerto Blanco mill was operating at less than 10% of capacity.

c. | The Soyatal oxide ore recovery problem has been solved, and high grade oxide concentrates can be produced. Oxide mineralized rock from dumps will be mined and underground development will be started when the need for raw materials increases.

d. | Explosives were permitted at Guadalupe in 2014, and underground development has started.

· | Assuming that Guadalupe and Los Juarez feed are going to the Puerto Blanco mill, the 500 ton per day mill that is estimated at 40% of completion will need to be completed.

· | Our cost of goods sold for antimony increased by approximately $1,958,000 for 2015 because of the increase in antimony sold. For the year ended December 31, 2015, costs of goods sold include operating and non-operating production costs from Mexico operations. Our switch to natural gas as a fuel for our smelter at Madero in the fourth quarter of 2014 has provided a significant improvement in our Mexico operating costs for 2015. Prior to 2015, the cost of propane was our second largest operating cost, and the switch to natural gas has decreased the per pound cost by 75%. The cost of goods sold during both years has been impacted by increases in the cost of operating supplies, fuel, trucking, insurance, refractory costs, and steel.

· | Our volume of zeolite sold was up 44%, from 11,079 tons in 2014 to 15,901 tons in 2015. The tons of zeolite sold decreased by approximately 100 tons in 2014 from 2013. Total revenue increased by approximately $584,000 in 2015 and decreased approximately $33,000 in 2014. Our cost of goods sold increased by approximately $452,206 for 2015, and increased by approximately $55,000 for 2014 from 2013. Cost of sales increased for 2015 primarily because we had an increase in the volume of product sold.

· | General and administrative costs, as reported in our statement of operations, include fees paid to directors through stock based compensation. In 2015 and 2014, we incurred $40,000 each year in fees to the NYSE MKT that was included in general and administrative expenses. General and administrative costs for 2015 and 2014 include general and administrative costs related to commencement of production at our facilities in Mexico. The combined general and administrative costs were 5.6%, and 5.8%, of sales for 2015 and 2014, respectively. The combined general and administrative salaries were 3.3%, and 3.9% of sales for 2015 and 2014, respectively.

38

· | The increase in professional fees for 2015 (approximately $73,000) was primarily due to increased costs related to our audits and financial statement preparation and for attorney fees related to alleged violations of an operating agreement with our former Investor Relations representative.

· | Factoring costs decreased in 2015 from approximately $49,000 in 2014 to approximately $41,000. Factoring costs decreased in 2014 by approximately $22,000 as we were able to reduce our collection time for accounts receivable. The discounts we gave for early payments increased by approximately $23,000 in 2015 from 2014.

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, 2015 and 2014 for impairment. Management’s assessment of the subsidiaries’ fair value was based on their future benefit to us.

Financial Condition and Liquidity |  |  |  |  |  |

Received on notes receivable for stock |  |  | 120,000 |  |  |  | 0 |
Net change in cash |  | $ | 9,860 |  |  | $ | 103,340 |

Our net working capital decreased for the year ended December 31, 2015, from a positive amount of $48,261 at the beginning of the year to a negative amount of $293,504 at the end of 2015. Our current assets decreased primarily due to an decrease in our inventories in Montana and in Mexico. The capital improvements were paid for with cash and debt. Our current liabilities increased in most categories during 2015.
During the year ending December 31, 2016, we are planning to finance our improvements with operating cash flow. Our 2016 improvements are expected to include completion of the installation at the Madero smelter, completion of cyanide leach circuits at both Madero and Puerto Blanco, and completing the installation of a 400 - 500 ton per day flotation mill at Puerto Blanco.
In 2015, cash used by operations was primarily due to our net loss of approximately $840,000 which was mostly offset by depreciation and amortization of approximately $932,000. We negotiated decreases in our current liabilities for raw material of approximately $915,000 during 2015.
39

The current portion of our long term debt is serviceable from the cash generated by operations.
Our stockholders’ equity section makes note that we have a liquidation preference of $5,884,376 for our preferred stock. This consists of a liquidation payment of $5,281,519 due if we liquidate our company or sell substantially all our assets, and $602,857 of undeclared dividends. The Board of Directors’ does not intend to declare dividends on preferred stock as due and payable at any time in the near future. We do not feel that the liquidation preference and undeclared dividends related to our preferred stock will be an impediment to raising capital in the future by issuing additional shares of common stock, and are not going to affect our liquidity.
Item 7A Quantitative and Qualitative Disclosures about Market Risk
We sell our antimony products based on a world market price. Our earnings and cash flow are significantly affected by changes in the price of antimony. The price of antimony can fluctuate widely and is influenced by numerous factors such as demand, production levels, and world political and economic events. During the past five years, our average sales price of antimony metal has ranged from a high of $7.43 per pound in 2011 to a low of $3.96 per pound in 2015. Analysis of our costs indicate that, for the year ended December 31, 2015, raw material costs were approximately 50% of our cost of revenues (cost of goods sold). Our raw material cost is tied to the sales price of antimony, but most of our production costs are fixed in nature, and could not be decreased readily without decreasing our production. During the year ended December 31, 2015, a $0.50 per pound decrease in our sales price would have likely caused our gross profit to decrease by $0.25 per pound. As we produce more of our raw material from our Mexico operations and our raw material cost becomes less affected by world prices, a decrease in our sales price will have a smaller impact on our cost of revenues.
Item 7B 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 purchased 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 purchased 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, 2015, 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 $51,000. 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 recovery 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 $11,837 for 2015). We will 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.

The consolidated financial statements of the registrant are included herein on pages F1-F23.
Item 9 Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
None
Item 9A Controls and Procedures
Evaluation of disclosure controls and procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, as appropriate, to allow timely decisions regarding required disclosure. Our Chief Financial Officer conducted an evaluation of the effectiveness of USAC’s disclosure controls and procedures (as defined in the Securities Exchange Act of 1934 Rules 13a-15(e) and 15d-15(e)) as of December 31, 2015. Based upon this evaluation, it was determined that there were material weaknesses affecting our internal control over financial reporting (described below) and, as a result of those weaknesses, our disclosure controls and procedures were ineffective as of December 31, 2015.
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, 2015. 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, 2015. 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

41

· | 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, 2015, 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, 2015.

| Compensation for all executive officers, except for the President/CEO position, is recommended to the compensation committee of the Board of Directors by the President/CEO. The compensation committee makes the recommendation for the compensation of the President/CEO. The compensation committee has identified a peer group of mining companies to aid in reviewing the President’s compensation recommendations for executives, and for reviewing the compensation of the President/CEO. The full Board approves the compensation amounts recommended by the compensation committee. Currently, the executive managements’ compensation only includes base salary and health insurance. The Company does not have annual performance based salary increases, long term performance based cash incentives, deferred compensation, retirement benefits, or disability benefits. For the year ended December 31, 2015, Russell Lawrence (VP) received an increase in base compensation of $15,000 annually. The Board of Directors determined that Mr. Lawrence’s compensation for the prior years was not adequate for the duties assigned to Mr. Russell as the Vice President for Latin America, and that a raise was appropriate to compensate for management of the Latin American operations.

| Two executive officers, the President/CEO and the Vice-President for the Latin American operations, receive restricted stock awards for their services as Board members.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of United States Antimony Corporation:
We have audited the accompanying consolidated balance sheets of United States Antimony Corporation and subsidiaries (“the Company”) as of December 31, 2015 and 2014, and the related consolidated statements of operations, changes in stockholders’ equity and cash flows for the years ended December 31, 2015 and 2014. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the consolidated financial statements based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of United States Antimony Corporation and Subsidiaries as of December 31, 2015 and 2015 and 2014, and the results of their consolidated operations and cash flows for the years ended December 31, 2015 and 2014, in conformity with accounting principles generally accepted in the United States of America.

United States Antimony Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2015 and 2014
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.

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 impairment, accounts receivable allowance, deferred income taxes, 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, 2015 and 2014 consists of cash held for reclamation performance bonds, and is held as 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, 2015 and 2014 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 are presented in United States (US) Dollars, and the US Dollar is the functional currency of the Company and its foreign subsidiaries. All transactions are carried out in US Dollars, or translated at the time of the transaction.

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 $3,451,317 and $1,901,490 in plant construction and other capital costs for the years ended December 31, 2015 and 2014, respectively. These amounts include capitalized interest of $66,965 and $81,703, 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.
Mineral Rights
The cost 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 if 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, 2015 or 2014 as a result of this assessment. Mineral rights are subject to write down in the period the property is abandoned.
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 SEC 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.

3.Summary of Significant Accounting Policies, continued:
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; 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 upon shipment and when title passes to the customer. Prepayments 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. The Company's sales agreements do not provide for product returns or allowances.
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 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, 2015, and 2014, does not add any shares to basic weighted average shares.
As of December 31, 2015 and 2014, potentially dilutive common stock equivalents not included in the calculation of diluted earnings per share are as follows:

|  | December 31, 2015 |  |  | December 31, 2014 |
Warrants |  |  | 250,000 |  |  |  | 726,917 |
Convertible preferred stock |  |  | 1,751,005 |  |  |  | 1,751,005 |
Total possible dilution |  |  | 2,001,005 |  |  |  | 2,477,922 |

3. Summary of Significant Accounting Policies, continued:
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 certificates of deposit, restricted cash, due to factor, and long-term debt approximates fair value based on the contractual terms of those instruments.
Fair Value Measurements
Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements”, requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. ASC 820 prioritizes the inputs into three levels that may be used to measure fair value.
The Company discloses the following information for each class of assets and liabilities that are measured at fair value:

1. | the fair value measurement;

2. | the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3);

3. | for fair value measurements using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to the following:

a. | total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings, and a description of where those gains or losses included in earnings are reported in the statement of operations;

b. | the amount of these gains or losses attributable to the change in unrealized gains or losses relating to those assets or liabilities still held at the reporting period date and a description of where those unrealized gains or losses are reported;

c. | purchases, sales, issuances, and settlements (net); and

d. | transfers into and/or out of Level 3.

4. | the amount of the total gains or losses for the period 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 and a description of where those unrealized gains or losses are reported in the statement of operations; and

5. | in annual periods only, the valuation technique(s) used to measure fair value and a discussion of changes in valuation techniques, if any, during the period.

The table below sets forth the Company’s financial assets that were accounted for at fair value on a recurring basis as of December 31, 2015 and 2014, respectively, and the fair value calculation input hierarchy level that the Company determined applies to each asset category.

|  |  |  |  |  |  | Input
|  |  |  |  |  |  | Hierarchy
Assets: |  | 2015 |  |  | 2014 |  | Level
Cash and cash equivalents |  | $ | 133,543 |  |  | $ | 123,683 |  | Level I

Recent Accounting Pronouncements
In July 2013, the FASB issued ASU 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (“ASU 2013-11”). ASU 2013-11 provides guidance on the presentation of unrecognized tax benefits related to any disallowed portion of net operating loss carryforwards, similar tax losses, or tax credit carryforwards, if they exist.
In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements—Going Concern.” The provisions of ASU No. 2014-15 require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term substantial doubt, (2) require an evaluation every reporting period including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). The amendments in this ASU are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. The Company is currently assessing the impact of ASU No. 2014-15 on the Company’s consolidated financial statements once adopted.
In May 2014, the Financial Accounting Standards Board ("FASB") issued 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 guidance establishes a new five step principle-based framework in an effort to significantly enhance comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets. ASU No. 2014-09 is effective for annual and interim reporting periods beginning after December 15, 2017. We are in the process of evaluating this guidance and our method of adoption.
In July 2015, the FASB issued ASU 2015-11 Inventory (Topic 330): Simplifying the Measurement of Inventory. The update provides for inventory to be measured at the lower of cost and net realizable value, and is effective for the fiscal years beginning after December 15, 2016. We are currently evaluating the potential impact of implementing this update on the consolidated financial statements.
In November 2015, the FASB issued ASU No. 2015-17 Income Taxes - Balance Sheet Classification of Deferred Taxes (Topic 740). The update is designed to reduce complexity of reporting deferred income tax liabilities and assets into current and non-current amounts in a statement of financial position. The FASB has proposed the presentation of deferred income taxes, changes to deferred tax liabilities and assets be classified as non-current in the statement of financial position. The update is effective for fiscal years beginning after December 15, 2016. ASU No. 2015-17 is not expected to have a material impact on our consolidated financial statements.
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. The Company does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.

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 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, 2015 |  |  | December 31, 2014 |
Accounts receivable - non factored |  | $ | 412,922 |  |  | $ | 445,391 |
Accounts receivable - factored with recourse |  |  | 13,782 |  |  |  | 13,314 |
less allowance for doubtful accounts |  |  | (4,031 | ) |  |  | (4,031 | )
Accounts receivable - net |  | $ | 422,673 |  |  | $ | 454,674 |

Factoring fees paid by the Company during the years ended December 31, 2015 and 2014, were $41,117 and $49,364, respectively. For the years ended December 31, 2015 and 2014, net accounts receivable of approximately $2.10 million and $2.30 million, respectively, were sold under the agreement.
Proceeds from the sales were used to fund inventory purchases and operating expenses. The agreement is for a term of one year with automatic renewal for additional one-year terms.
5.Inventories
The major components of the Company's inventories at December 31, 2015 and 2014 were as follows:

|  | 2015 |  |  | 2014 |
Antimony Metal |  | $ | 102,207 |  |  | $ | 40,352 |
Antimony Oxide |  |  | 332,068 |  |  |  | 718,982 |
Antimony Concentrates |  |  | 133,954 |  |  |  | 33,545 |
Antimony Ore |  |  | 319,631 |  |  |  | 447,262 |
Total antimony |  |  | 887,860 |  |  |  | 1,240,141 |
Zeolite |  |  | 206,378 |  |  |  | 193,398 |
|  | $ | 1,094,238 |  |  | $ | 1,433,539 |

At December 31, 2015 and 2014, antimony metal consisted principally of recast metal from antimony-based compounds, and metal purchased from foreign suppliers. Antimony oxide inventory consisted of finished product oxide held at the Company's plant. Antimony concentrates and ore was held primarily at sites in Mexico and is essentially raw material, carried at cost. At December 31, 2015, antimony inventory is valued at net realizable value. The Company's zeolite inventory consists of salable zeolite material held at BRZ's Idaho mining and production facility, and is carried at cost.

5.Inventories, Continued:
Gain on Liability Adjustment
During the first quarter of 2015, we noted that the amounts we were being invoiced by our Canadian supplier did not appear to be in compliance with our understanding of what we should be paying for the raw material supplied by them. We determined that since April of 2012 the supplier had been billing us for the entire amount of pounds of antimony delivered to us, even though we believed that we should only pay for 90% of the delivered antimony since we lost approximately 10% in processing. We contacted the supplier, and after a mutual review and modification of information that we had supplied to them, the supplier proposed a settlement of $914,770 to be credited against amounts we owed them. We agreed to the settlement amount and recorded it as a reduction of an account payable to the supplier and recognized a gain on liability adjustment in our statement of operations.

The Company’s total asset retirement obligation and accrued reclamation costs of $260,327 and $255,190 at December 31, 2015 and 2014, respectively, include reclamation obligations for Idaho and Montana operations of $107,500.
8.Other Assets
Guadalupe
On March 7, 2012 and on April 4, 2012 the Company entered into a supply agreement and a loan agreement, respectively, (“the Agreements”) with several individuals collectively referred to as ‘Grupo Roga’ or ‘Guadalupe.’ During the term of the supply agreement the Company funded certain of Guadalupe’s equipment purchases, tax payments, labor costs, milling and trucking costs, and other expenses incurred in the Guadalupe mining operations for approximately $112,000. In addition to the advances for mining costs, the Company purchased antimony ore from Guadalupe that failed to meet agreed upon antimony metal recoveries and resulted in approximately $475,000 of excess advances paid to Guadalupe.
The Agreements with Guadalupe granted the Company an option to purchase the concessions outright for $2,000,000. On September 29, 2015, the Company notified the owners of Guadalupe that it was exercising the option to purchase the Guadalupe property. The option exercise agreement allowed the Company to apply all amounts previously due the Company by Guadalupe of $586,893 to the purchase price consideration, resulting in a net obligation for the purchase of the Guadalupe mine of $1,413,107. The Company is obligated to make annual payments that vary from $60,000 to $149,077 annually through 2026. The debt payments are non-interest bearing. The Company determined the net present value of the future contractual stream of payments to be $972,722 using a 6% discount rate. The Company recorded $972,722 as the cost of the concessions and the debt payable equal to total payments due of $1,413,107 less a discount of $440,385. The discount is being amortized to interest expense using the effective interest method over the life of the debt. As of December 31, 2015, the Company had made $15,000 in payments toward this debt and amortized $14,591 of discount as interest expense. The net balance of the debt at December 31, 2015 was $972,312.

| These notes are personally guaranteed by John C. Lawrence the Company’s President and Chairman of the Board of Directors. The maximum amount available for borrowing under each note is $99,998. There were no notes payable to bank at December 31, 2014.

11. Hillgrove Advances Payable

| On November 7, 2014, the Company entered into a loan and processing agreement with Hillgrove Mines Pty Ltd of Australia (Hillgrove) by which Hillgrove will advance the Company funds to be used to expand their 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 requires that the Company construct equipment so that it can process approximately 200 metric tons of concentrate initially shipped by Hillgrove, with a provision so that the Company may expand to process more than that. The parties agreed that the equipment will be owned by USAC and USAMSA. The final terms of when the repayment takes place have not yet been agreed on. 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 as approved by Hillgrove, and to charge a 7.5% processing fee and a 2.0% sales commission. 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. If a stop notice is issued between one year and two years, there is a formula to prorate the repayment amount from 50% to 81.25%. If a stop order is issued after two years, the repayment obligation is 81.25% of the funds advanced at that point. At December 31, 2015, management has determined that it is likely that the Company’s repayment obligation will be 81.25% of the total amounts advanced. As of December 31, 2015, Hillgrove has advanced the Company a total of $1,397,016. Of this amount, approximately 18.75% or $262,408 has been recorded as deferred earned credit and is being recognized ratably through the period ending November 7, 2016 which is when the 81.25% repayment terms of the agreement is applicable. During the year ended December 31, 2015, $125,191 of the deferred earned credit was recognized with the remaining balance of $120,238 to be recognized in 2016. At December 31, 2015, the amount due to Hillgrove for the advances is $1,134,608 which is approximately 81.25% of the total amount advanced.

At December 31, 2015, the Company has United States net operating loss carry forwards of approximately $186,000 that expire at various dates between 2030 and 2035. In addition, the Company has Montana state net operating loss carry forwards of approximately $2,313,000 which expire between 2017 and 2022, and Idaho state net operating loss carry forwards of approximately $940,000, which expire between 2033 and 2035.

At December 31 2015 and 2014, 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, 2015 and 2014.
The income tax provision differs from the amount of income tax determined by applying the U.S. federal income tax rate to pretax loss for the years ended December 31, 2015 and 2014, due to the following:

During the year ended December 31, 2015, Mexican Tax authorities (‘SAT’) initiated an audit of the Company's Mexican subsidiary’s return for the year ended December 31, 2013. Management has reviewed its tax positions and does not believe it is reasonably possible that its unrecognized tax benefits would materially change in the next twelve months. If an issue addressed during the SAT audit is resolved in a manner inconsistent with management expectations, the Company would adjust its net operating loss carryforward, or accrue any penalties, interest, and tax associated with the audit. The audit is expected to be complete during 2016.
During the years ended December 31, 2015 and 2014, there were no material uncertain tax positions taken by the Company. The Company United States income tax filings are subject to examination for the years 2013 through 2015, and 2011 and 2015 in Mexico. In the event that the Company is assessed penalties and or interest, penalties will be charged to other operating expense and interest will be charged to interest expense.
15.Related-Party Transactions
The Company’s President and Chairman, John Lawrence, rents equipment and an aircraft to the Company and charges the Company for lodging and meals provided to consultants, customers and other parties by an entity that Mr. Lawrence owns. Transactions due to (due from) Mr. Lawrence during 2015 and 2014 were as follows:

|  | 2015 |  |  | 2014 |
Balance, beginning of year |  | $ | 8,357 |  |  | $ | 15,549 |

In addition, during 2014, Mr. Lawrence loaned the Company $65,300 for short-term operating capital and was paid back without interest during 2014.
16.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 years ended December 31, 2015 and 2014, $127,500 and $200,000, respectively, was paid and capitalized as mineral rights in accordance with the Company’s accounting policies. At December 31, 2015, the following payments are scheduled: $65,000 by March 31, 2016.
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 $29,000 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 2015.
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, 2015 and 2014, the Company has no accruals relating to such assessments.

16.Commitments and Contingencies, Continued:
In prior years, the Company utilized Providence Capital, Inc., a Delaware corporation (“Providence”), and Herbert A. Denton to provide investor relations services. On April 1, 2015, we entered into an agreement with Providence to provide us services as our Investor Relations Representative. We terminated this agreement in May 2015, and signed a Settlement Agreement dated July 27, 2015, and a Supplemental Settlement Agreement dated August 1, 2015. These agreements provided for a payment to Mr. Denton of 100,000 shares of the Company’s common stock and $25,000 to be paid in five equal installments. On August 31, 2015, we issued 100,000 shares of common stock valued at $0.55 per share or $55,000 to Mr. Denton. On October 12, 2015, we served Mr. Denton with a notice of material breach of the termination agreements and suspended the remaining payments of $15,000. We have subsequently filed an action in federal court to force Mr. Denton to comply with the terms of the termination agreements and for damages related to his non-compliance. Subsequent to the Company’s filing, Mr. Denton filed a counterclaim against the Company seeking an award for damages for breach of contract, conversion, defamation of character, failure to exercise business judgement and intentional infliction of emotional duress and damage to reputation. Management believes that the likelihood of an unfavorable outcome in the litigation is remote and intends on defending the claim vigorously. Accordingly, management has not accrued any amount on its financial statements related to a potential contingent liability.
17. Business Segments
The Company is currently organized and managed by three segments, which represent the operating units: United States antimony operations, Mexican antimony operations and United States zeolite operations. 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.
Segment disclosures regarding sales to major customers and for property, plant, and equipment are located in Notes 2 and 6, respectively.
