SUMMARY

The following summary highlights selected information contained elsewhere in this prospectus supplement and in the documents incorporated by reference in this prospectus supplement and does not contain all the information you will need in making your investment decision. You should read carefully this entire prospectus supplement, the attached prospectus and the documents incorporated by reference in this prospectus supplement.

United States Antimony Corporation

Our Business

We are a fully-integrated natural resource company engaged in the mining, milling, smelting, transportation and sale of antimony products, as well as zeolite and silver and gold. Our operations include a smelter and precious metal refinery in Montana, and a smelter and three mills in Mexico.

Antimony Division

Our antimony smelter and precious metals plant in Montana is located in the Burns Mining District of Sanders County, approximately 15 miles west of Thompson Falls, Montana. We hold two patented mill sites where our 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 our Montana site.

Since 1983, we have depended 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 and, although we are still partially reliant on foreign companies for raw material, we anticipate that a majority of our raw materials will come from Canada and our own properties for 2014 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 lease 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 property. USAMSA has three assets (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 in late 2012, (3) part of the Los Juarez mineral deposit that includes concessions in Queretaro that began producing ore in late 2012 and the Soyatal mineral deposit that was starting production in 2013.

A larger 500 ton mill is currently being installed at Puerto Bianco in Mexico. Five Mexican properties supply direct shipping or DSO, and mill feed for our Mexican operations. Our Los Juarez property in Mexico is commencing silver and gold production which will supplement our antimony business.

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 pterathalate 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.

S-1

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 <1%, respectively. We are the only significant U.S. producer of antimony products, while China supplies 92% of the world antimony demand. We believe we are competitive both domestically and world-wide due to the following:

● We have a reputation for quality products delivered on a timely basis;

● We 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 U.S. domestic producer of antimony products;

● We are vertically integrated, with raw materials from our own mines, mills and smelter in Mexico;

● We have numerous ore and raw material suppliers based on exclusive supply agreements; and

● We have more control over our raw material costs as a vertically integrated supplier.

Zeolite Division

Bear River Zeolite Company, or BRZ, is our wholly owned Idaho subsidiary, which has a lease that entitles it to surface mine and process zeolite on property located near Preston, Idaho, in exchange for a royalty payment of $10 per ton sold, with a minimum annual royalty of $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 $3,392,000 to purchase and construct the processing plant as of December 31, 2013.

We have no “proven reserves” or “probable reserves” of zeolite, as these terms are defined by the SEC.

“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 is 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 crops, including corn, potatoes, soybeans, red beets, acorn squash, green beans, sorghum sudangrass, brussel sprouts, cabbage, carrots, tomatoes, cauliflower, radishes, strawberries, wheat, lettuce and broccoli.

	●	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. Zeolilte can also be used for the cleanup of soluble metals such as mercury, chromium, copper, lead, zinc, arsenic, molybdenum, nickel, cobalt, antimony, calcium, silver and uranium.

	●	Odor Control. A major cause of odor around cattle, hog and poultry feed lots is the generation of the ammonium in urea and manure. The ability of zeolite to absorb ammonium prevents the formation of ammonia gas, which disperses the odor.

S-2

	●	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 at organic waste, sanitary landfills, municipal sewage systems and animal waste treatment facilities.

	●	Animal Nutrition. Feeding up to 2% zeolite increases the nitrogen content in manure and enhances odor control.

	●	Miscellaneous Uses. Other uses include catalysts for petroleum refining, concrete replacement, 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, commonly known as 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, 2013, we have accrued $100,000 to fulfill our environmental responsibilities.

S-3

BRZ

During 2001, we recorded a reclamation accrual for our BRZ subsidiary, based on an analysis performed by us and reviewed and approved by regulatory authorities for environmental bonding purposes. The accrual of $7,500 represents our estimated costs of reclaiming, in accordance with regulatory requirements, the acreage disturbed by our zeolite operations, which remains unchanged at December 31, 2013.

Mexico

During 2011, we recorded an asset retirement obligation, or ARO, for our Mexican subsidiaries, based on an analysis performed by us and the reclamation requirements of Mexican permitting authorities. The ARO primarily relates to our permit for the Los Juarez Mine and Corral Blanco Mill. The accrual of $150,080 represents our estimated discounted costs of reclamation, in accordance with permitting requirements, at December 31, 2013.

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, 2013. 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.

Our Company

We were 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. On May 16, 2012, we started trading on the NYSE MKT under the symbol UAMY.

We currently maintain an administrative office at 47 Cox Gulch Road, Thompson Falls, Montana 59873. The telephone number of our administrative office is (406) 827-3523.

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider all of the information set forth in this prospectus supplement, the accompanying prospectus and the information incorporated by reference herein and therein. In particular, you should evaluate the following risk factors before making an investment decision in our common stock. If any of the following circumstances actually occur, our business, financial condition and results of operations could be materially and adversely affected. If that occurs, the trading price of our common stock could decline, and you could lose all or part of your investment.

Estimates of mineralized material are forward-looking statements inherently subject to error. Although resource estimates require a high degree of assurance in the underlying data when the estimates are made, unforeseen events and uncontrollable factors can have significant adverse or positive impacts on the estimates. Actual results will inherently differ from estimates. The unforeseen events and uncontrollable factors include: geologic uncertainties including inherent sample variability, mineral price fluctuations, variations in mining and processing parameters, and adverse changes in environmental or mining laws and regulations. The timing and effects of variances from estimated values cannot be accurately predicted.

Risks Associated With Our Business

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 U.S. and Mexican environmental and occupational safety laws and regulations governing the use, manufacture, storage, handling, and disposal of hazardous materials and some waste products. The risk of accidental contamination or injury from hazardous materials cannot be completely eliminated. In the event of an accident, we could be held liable for any damages that result and any liability could exceed our financial resources. We also have one ongoing environmental reclamation and remediation projects at our current production facility in Montana. Adequate financial resources may not be available to ultimately finish the reclamation activities if changes in environmental laws and regulations occur, and these changes could adversely affect our cash flow and profitability. We do not have environmental liability insurance now, and we do not expect to be able to obtain insurance at a reasonable cost. If we incur liability for environmental damages while we are uninsured, it could have a harmful effect on our financial condition and results of operations. The range of reasonably possible losses from our exposure to environmental liabilities in excess of amounts accrued to date cannot be reasonably estimated at this time.

We have accruals for asset retirement obligations and environmental obligations.

We have accruals totaling $257,580 on our balance sheet at December 31, 2013, 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.

Our operations are subject to applicable law and government regulation.

Both mineral exploration and extraction require permits from various foreign, federal, state, provincial and local governmental authorities and are governed by laws and regulations, including those with respect to mine and mill development, mineral smelting and production, transport, export, taxation, labor standards, occupational health, waste disposal, toxic substances, land use, environmental protection, mine safety and other matters.

We believe that we are in compliance with all material laws and regulations that currently apply to our activities but there can be no assurance that we can continue to do so. Current laws and regulations could be amended and we might not be able to comply with them, as amended. Further, there can be no assurance that we will be able to obtain or maintain all permits necessary for our future operations, or that we will be able to obtain them on reasonable terms. To the extent such approvals are required and are not obtained, we may be delayed or prohibited from proceeding with planned exploration or development of our mineral properties.

S-6

Future legislation and administrative changes to the mining laws could prevent us from exploring our properties.

New state and U.S. federal laws and regulations, and Mexican laws and regulations, amendments to existing laws and regulations, administrative interpretation of existing laws and regulations, or more stringent enforcement of existing laws and regulations, could have a material adverse impact on our ability to conduct exploration and mining activities. Any change in the regulatory structure making it more expensive to engage in mining activities could cause us to cease operations.

Regulations and pending legislation governing issues involving climate change could result in increased operating costs, which could have a material adverse effect on our business.

A number of governments or governmental bodies have introduced or are contemplating regulatory changes in response to various climate change interest groups and the potential impact of climate change. Foreign or domestic legislation and increased regulation regarding climate change could impose significant costs on us and on our suppliers, including costs related to increased energy requirements, capital equipment, environmental monitoring and reporting and other costs to comply with such regulations. Any adopted future climate change regulations could also negatively impact our ability to compete with companies situated in areas not subject to such limitations. Given the emotion, political significance and uncertainty around the impact of climate change and how it should be dealt with, we cannot predict how legislation and regulation will affect our financial condition, operating performance and ability to compete. Furthermore, even without such regulation, increased awareness and any adverse publicity in the global marketplace about potential impacts on climate change by us or other companies in our industry could harm our reputation. The potential physical impacts of climate change on our operations are highly uncertain, and would be particular to the geographic circumstances in areas in which we operate. These may include changes in rainfall and storm patterns and intensities, water shortages, changing sea levels and changing temperatures. These impacts may adversely impact the cost, production and financial performance of our operations.

Mining operations are inherently dangerous and subject to conditions or events beyond our control, which could have a material adverse effect on our business and plans.

Mining, milling and smelting operations involve various types of risks and hazards, including:

● environmental hazards;

● power outages;

● metallurgical and other processing problems;

● unusual or unexpected geological formations;

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

● inability to obtain suitable or adequate machinery, equipment, or labor;

● metals losses;

● fluctuations in development, production, milling and smelting costs;

● labor disputes;

● unanticipated variations in grade;

● mechanical equipment failure; and

● periodic interruptions due to inclement or hazardous weather conditions.

These risks could result in damage to, or destruction of, mineral properties, production facilities or other properties, personal injury, environmental damage, delays in mining, increased production costs, monetary losses and possible legal liability.

S-7

Mining operations are subject to extraordinary operating risks. We do not currently insure against these risks. In the event of a cave-in or similar occurrence, our liability may exceed our resources, which would have an adverse impact on us.

Mining operations involve many risks, which even a combination of experience, knowledge and careful evaluation may not be able to overcome. Our operations will be subject to all the hazards and risks inherent in the exploration, development and production of minerals, including liability for pollution, cave-ins or similar hazards against which we cannot insure or against which we may elect not to insure. Any such event could result in work stoppages and damage to property, including damage to the environment. We do not currently maintain any insurance coverage against these operating hazards. The payment of any liabilities that arise from any such occurrence would have a material, adverse impact on us and our results of operations.

Any product recall or product return could harm our customer relations, sales and profitability.

Our antimony and zeolite products are typically manufactured to meet individual customer specifications, including maximum tolerance levels for impurities, whiteness, color index, packaging requirements and bar coding. Failure to meet those specifications may result in product recalls or returns. Product recalls or returns may occur due to disputed labeling claims, manufacturing issues, quality defects or other reasons.

Increased costs could affect our financial condition.

We anticipate that costs at our projects will frequently be subject to variation from one year to the next due to a number of factors, such as changing ore grade, metallurgy and revisions to mine and mill plans, if any, in response to the physical shape and location of the ore body. In addition, costs are affected by the price of commodities such as fuel, rubber and electricity. Such commodities are at times subject to volatile price movements, including increases that could make production at certain operations less profitable. A material increase in costs at any significant location could have a significant effect on our profitability.

A shortage of equipment and supplies could adversely affect our ability to operate our business.

We are dependent on various supplies and equipment to carry out our mining, milling and smelting operations. The shortage of such supplies, equipment and parts could have a material adverse effect on our ability to carry out our operations and therefore limit or increase the cost of production.

Mineral prices are subject to dramatic and unpredictable fluctuations.

We derive our revenues from the extraction, milling and sale of precious and base metals and minerals, such as antimony, zeolite, silver and gold. The price of those commodities has fluctuated widely in recent years, and is affected by numerous factors beyond our control including international, economic and political trends, expectations of inflation, currency exchange fluctuations, interest rates, global or regional consumptive patterns, speculative activities and increased production due to new extraction developments and improved extraction and production methods.

The antimony industry is highly competitive.

The antimony industry is highly competitive. By far the largest production of antimony comes from Chinese companies, many of whom have greater financial resources and technical facilities. Accordingly, we will attempt to compete primarily through the knowledge and experience of our management, our presence in North and South America and our operating efficiencies. There can be no assurance that we will acquire any interest in additional mineral properties that might yield reserves or result in commercial mining operations.

Although we are steadily increasing our own supply of raw materials, we remain dependent on foreign sources for raw materials.

While we anticipate that a significant amount of our raw materials will come from our Mexican properties by the end of 2014 and thereafter, we will remain dependent on suppliers of raw materials in North America, Central America, Europe, Australia and South America. There are risks of interruption in procurement from these sources, as well as currency fluctuations that are outside our control. Unavailability of adequate raw materials or increase in material prices could impair our product, sales and margins.

S-8

Risks Related To Our Company

Unexpected fluctuations in our quarterly operating results may cause our stock price to decline.

A large proportion of our costs, including our selling, general and administrative expenses, environmental reclamation costs, research and development costs and production costs, do not vary directly in relation to sales. Thus, declines in revenue, even if small, could disproportionately affect our quarterly operating results, could cause such results to differ materially from expectations and could cause our stock price to decline.

If we were liquidated, our common shareholders 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 have incurred significant losses.

We incurred net losses of $1,641,170 and $558,536 in the fiscal years ended December 31, 2013 and 2012, respectively. We expect to continue to incur losses into the foreseeable future. We recognize that if we are unable to generate significant revenues from our antimony and zeolite operations, we will not be able to earn profits or continue operations. There can be no assurance as to the likelihood that we will prove successful and we can provide investors with no assurance that we will generate any operating revenues or ever achieve profitable operations.

Conflicts of interest.

Certain of our officers and directors may be or become associated with other businesses, including natural resource companies that acquire interests in mineral properties. Such associations may give rise to conflicts of interest from time to time. Our directors are required by the Montana Business Corporations Act to act honestly and in good faith with a view to our best interests and to disclose any interest which they may have in any of our projects or opportunities. In general, if a conflict of interest arises at a meeting of the board of directors, any director in a conflict will disclose his interest and abstain from voting on such matter or, if he does vote, his vote will not be counted.

We have adopted a separate formal corporate policy regarding conflicts of interest; in addition, we have adopted other corporate governance measures, such as creating a directors’ audit committee requiring independent directors. As of the date of filing of this report, we had three independent directors on our board of directors (Gary D. Babbitt, Hartmut W. Baitis and Whitney H. Ferer). The Company has formed three committees to ensure our compliance with the requirements of the NYSE MKT exchange. We established an independent audit committee consisting of three independent directors, all of whom were determined to be “financially literate” and one of whom was designated as the “financial expert”. We also formed a compensation committee and a corporate governance and nominating committee, both of which are comprised entirely of independent directors. At this time, we feel that these committees, our conflicts of interest policy and our Code of Ethics provide sufficient corporate governance for our purposes and will meet the specific requirements of the NYSE MKT exchange.

Dependence on key management employees.

The nature of both divisions of our business, our ability to continue our mining, milling and smelting operations and to develop a competitive edge in the marketplace depends, in large part, on our ability to attract and maintain qualified key management personnel. Competition for such personnel is intense, and there can be no assurance that we will be able to attract and retain such personnel. Our development now and in the future will depend on the efforts of key management figures, such as John C. Lawrence, Russell C. Lawrence and Daniel L. Parks. The loss of any of these key people could have a material adverse effect on our business. In particular, John Lawrence—our principal executive officer—is directly involved, on a day-to-day basis, in our production, marketing, research and development and other operations. Accordingly, his death or incapacity could adversely affect our operations and future prospects.

Risks Related to This Offering

Investors in this offering will pay a much higher price than the book value of our stock.

If you purchase common stock in this offering, you will incur immediate and substantial dilution in tangible book value of $1.20 per share, after giving effect to the sale by us of 1,453,288 shares in this offering at the public offering price of $1.40 per share. Net tangible book value per share represents our total tangible assets less our total liabilities, divided by the aggregate number of shares of our common stock outstanding.

Our stock price has been volatile and your investment in our common stock could suffer a decline in value.

Our common stock is traded on the NYSE MKT. The market price of our common stock may fluctuate significantly in response to a number of factors, some of which are beyond our control. These factors include price fluctuations of minerals and metals, government regulations, disputes regarding mining claims, broad stock market fluctuations and economic conditions in the United States and Mexico.

We do not intend to pay any dividends on shares of our common stock in the near future. Consequently, your only opportunity currently to achieve a return on your investment will be if the market price of our shares of common stock appreciates above the price that you pay for our shares of common stock.

We do not currently anticipate declaring and paying dividends to our shareholders in the near future, and any future decision as to the payment of dividends will be at the discretion of our board of directors and will depend upon our earnings, financial position, capital requirements, plans for expansion and such other factors as our board of directors deems relevant. It is our current intention to apply net earnings, if any, in the foreseeable future to finance the growth and development of our business.

Management will have broad discretion as to the use of the proceeds from any offering under this prospectus, and we may not use the proceeds effectively or in a manner that increases the value of your investment.

We have designated $950,000 of the net proceeds from any offering under this prospectus to be used for capital expenses, including the purchase of additional furnaces and permitting of additional land at our smelter in Maderos, Mexico, a drill rig for Los Juarez and completion of our 500 ton per day mill at Puerto Bianco. The balance of such net proceeds ($935,000) are unallocated other than for general working capital purposes. Accordingly, our management will have broad discretion as to the application of the net proceeds from any such offering and could use them for purposes other than those contemplated at the time of such offering. Our shareholders may not agree with the manner in which our management chooses to allocate and spend the net proceeds. Moreover, our management may use the net proceeds for corporate purposes that may not increase our profitability or market value.

Investors’ interests in us will be diluted and investors may suffer dilution in their net book value per share if we issue additional employee/director/consultant options or if we sell additional shares to finance our operations.

In order to capitalize on our resources in Mexico, we may need additional capital to be financed through sale of and issuance of additional shares. We may also in the future grant to some or all of our directors, officers, insiders, and key employees options to purchase our common shares as non-cash incentives. The issuance of any equity securities could, and the issuance of any additional shares will, cause our existing shareholders to experience dilution of their ownership interests.

PRICE RANGE OF COMMON STOCK AND DIVIDENDS

Currently, our common stock is traded on the NYSE-MKT under the symbol UAMY. Prior to May 16, 2012, our common stock was traded over the Counter Bulletin Board ("OTCBB") under the symbol "UAMY.OB." The following table sets forth the range of high and low bid prices as reported for the periods indicated. The quotations were taken from a website available to the public, and generally believed to be accurate. The quoted prices may not necessarily represent actual transactions.

2013	High		Low
First Quarter	$	2.34	$	1.64
Second Quarter		1.92		0.96
Third Quarter		1.73		0.90
Fourth Quarter		2.19		1.24

On June 26, 2014, the last sale price for our common stock as reported by the NYSE MKT was $1.66 per share.

We have not declared or paid any dividends to our stockholders during the last five years and do not anticipate paying dividends on our common stock in the foreseeable future. Instead, we expect to retain earnings for the operation and expansion of our business.

DILUTION

Our net tangible book value (unaudited) at March 31, 2014, was approximately $11 million, or approximately $0.17 per share, based on 63,281,206 shares of our common stock outstanding as of March 31, 2014. After giving effect to the sale of 1,453,288 shares by us at our public offering price of $1.40 per share, less the estimated placement agent’s fees and estimated offering expenses we expect to pay, our net tangible book value (unaudited) at March 31, 2014, would have been approximately $12.7 million, or approximately $0.20 per share. This represents an immediate increase in the net tangible book value of approximately $0.03 per share to existing shareholders and an immediate dilution of approximately $1.20 per share to investors in this offering. The following table illustrates this per share dilution:

Public offering price per share			$	1.40
Net tangible book value per share as of March 31, 2014	$	0.17
In Increase in net tangible book value per share attributable to new investors		0.03
As ad As adjusted net tangible book value per share after this offering	$	0.20
Dilution per share to new investors			$	1.20

The above discussion and table are based on 63,281,206 shares of our common stock outstanding as of March 31, 2014. The information above excludes:

●	2,364,407 warrants to purchase our common stock at exercise prices ranging between $0.60-$4.50 per share.

●	1,751,005 shares of convertible preferred stock, convertible to common shares on a share-for-share basis

SUMMARY

Our Business

Antimony Division

● 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 U.S. domestic producer of antimony products;

● We are vertically integrated, with raw materials from our own mines, mills and smelter in Mexico;

● We have numerous ore and raw material suppliers based on exclusive supply agreements; and

● We have more control over our raw material costs as a vertically integrated supplier.

Zeolite Division

We have no “proven reserves” or “probable reserves” of zeolite, as these terms are defined by the SEC.

	●	Soil Amendment and Fertilizer. Zeolite has been successfully used to fertilize golf courses, sports fields, parks and common areas, and high value crops, including corn, potatoes, soybeans, red beets, acorn squash, green beans, sorghum sudangrass, brussel sprouts, cabbage, carrots, tomatoes, cauliflower, radishes, strawberries, wheat, lettuce and broccoli.
	●	Water Filtration. Zeolite is used for particulate, heavy metal and ammonium removal in swimming pools, municipal water systems, fisheries, fish farms, and aquariums.
	●	Sewage Treatment. Zeolite is used in sewage treatment plants to remove nitrogen and as a carrier for microorganisms.
	●	Nuclear Waste and Other Environmental Cleanup. Zeolite has shown a strong ability to selectively remove strontium, cesium, radium, uranium, and various other radioactive isotopes from solution. Zeolite can also be used for the cleanup of soluble metals such as mercury, chromium, copper, lead, zinc, arsenic, molybdenum, nickel, cobalt, antimony, calcium, silver and uranium.
	●	Odor Control. A major cause of odor around cattle, hog, and poultry feed lots is the generation of the ammonium in urea and manure. The ability of zeolite to absorb ammonium prevents the formation of ammonia gas, which disperses the odor.
	●	Gas Separation. Zeolite has been used for some time to separate gases, to re-oxygenate downstream water from sewage plants, smelters, pulp and paper plants, and fish ponds and tanks, and to remove carbon dioxide, sulfur dioxide and hydrogen sulfide from methane generators as organic waste, sanitary landfills, municipal sewage systems and animal waste treatment facilities.
	●	Animal Nutrition. Feeding up to 2% zeolite increases the nitrogen content in manure and enhances odor control.
	●	Miscellaneous Uses. Other uses include catalysts for petroleum refining, concrete replacement, solar energy and heat exchange, desiccants, pellet binding, horse and kitty litter, floor cleaner and carriers for insecticides, pesticides and herbicides.

We have accruals for asset retirement obligations and environmental obligations.

Our operations are subject to applicable law and government regulation.

Future legislation and administrative changes to the mining laws could prevent us from exploring our properties.

Regulations and pending legislation governing issues involving climate change could result in increased operating costs, which could have a material adverse effect on our business.

Mining operations are inherently dangerous and subject to conditions or events beyond our control, which could have a material adverse effect on our business and plans.

Mining, milling and smelting operations involve various types of risks and hazards, including:

● environmental hazards;

● power outages;

● metallurgical and other processing problems;

● unusual or unexpected geological formations;

Increased costs could affect our financial condition.

A shortage of equipment and supplies could adversely affect our ability to operate our business.

Mineral prices are subject to dramatic and unpredictable fluctuations.

The antimony industry is highly competitive.

Although we are steadily increasing our own supply of raw materials, we remain dependent on foreign sources for raw materials.

Unexpected fluctuations in our quarterly operating results may cause our stock price to decline.

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

We have incurred significant losses.

Risks Related to This Offering

Our stock price has been volatile and your investment in our common stock could suffer a decline in value.

If all $5,000,000 of common stock is sold, the balance of such net proceeds ($3,450,000) are unallocated other than for general working capital purposes. Accordingly, our management will have broad discretion as to the application of the net proceeds from any such offering and could use them for purposes other than those contemplated at the time of such offering. Our shareholders may not agree with the manner in which our management chooses to allocate and spend the net proceeds. Moreover, our management may use the net proceeds for corporate purposes that may not increase our profitability or market value.

DESCRIPTION OF SECURITIES

Common Stock

We are authorized to issue 90,000,000 shares of our common stock, par value $0.01, each share of common stock having equal rights and preferences. There were 63,365,151 shares of common stock outstanding at the close of business on June 26, 2014.

The shares of our common stock constitute equity interests in the Company entitling each shareholder to a pro rata share of cash distributions made to common shareholders, including dividend payments. We had net losses in our last fiscal year. Therefore, it is unlikely that we will pay dividends on our common stock in the next year. We currently intend to retain our future earnings, if any, for use in our business. Any dividends declared in the future will be at the discretion of our Board of Directors and subject to any restrictions that may be imposed by our lenders.

The holders of our common stock are entitled to one vote for each share of record. Shareholders are entitled to vote cumulatively with respect to the election of directors of the Company. Directors are elected by a plurality of the votes cast by the voting stock entitled to vote at a meeting if a quorum is present. With respect to matters other than the election of directors, such matters must be approved by a majority of the votes entitled to be cast by all shares of common stock that are present in person or represented by proxy. Holders of shares of our common stock representing a majority of our capital stock issued, outstanding and entitled to vote, represented in person or by proxy, are necessary to constitute a quorum at any meeting of our shareholders. A vote by the holders of a majority of our outstanding shares of common stock is required to effectuate certain fundamental corporate changes such as liquidation, merger or an amendment to our Articles of Incorporation.

In the event of our liquidation, dissolution or winding up, the holders of common stock are entitled to share ratably in all assets remaining for distribution to them after payment of our liabilities and after provision has been made for each class of stock having preference in relation to our common stock. Holders of our common stock have no conversion, preemptive or other subscription rights, and there are no redemption provisions applicable to our common stock. All of the outstanding shares of our common stock are duly authorized, validly issued, fully paid and non-assessable.

In the event of any merger or consolidation with or into another company in connection with which shares of our common stock are converted into or exchangeable for shares of stock, other securities or property (including cash), all holders of shares of our common stock will be entitled to receive the same kind and amount of shares of stock and other securities and property (including cash).

Preferred Stock

We are authorized to issue up to 10,000,000 shares of preferred stock, 177,904 shares of Series C preferred stock, and (iii) 1,751,005 shares of Series D preferred stock. Subject to amounts of outstanding preferred stock, additional shares of our preferred stock may be divided into and issued in one or more additional series. Our board of directors is authorized to divide the authorized but unissued shares of preferred stock into one or more series, each of which shall be so designated as to distinguish the shares thereof from the shares of all other series and classes. Our board of directors is authorized, within the limitations prescribed by law and its Articles of Incorporation, to fix and determine the designations, rights, qualifications, preferences, limitations and terms of the shares of any series of preferred stock.

The following is a description of our outstanding series of preferred stock (there are no shares of Series A preferred stock outstanding):

Series B Preferred Stock

During 1993, the Board of Directors established a Series B preferred stock, consisting of 750,000 shares. The Series B preferred stock has preference over the Company’s common stock, has no voting rights and is entitled to cumulative dividends of $.01 per share per year, payable if and when declared by the Board of Directors. In the event of dissolution or liquidation of the Company, the preferential amount payable to Series B preferred shareholders is $1.00 per share plus dividends in arrears. No dividends have been declared or paid with respect to the Series B preferred stock. The Series B preferred stock is no longer convertible to shares of the Company’s common stock. At December 31, 2013, cumulative dividends in arrears on the outstanding Series B shares were $135,000 and the aggregate Series B liquidation preference at December 31, 2013 was $892,500.

Series C Preferred Stock

During 2000, the Board established a Series C preferred stock, consisting of 205,996 shares. In 2002, 28,092 shares were converted to common stock and cancelled, leaving 177,904 shares of Series C preferred stock authorized and outstanding. The Series C preferred stock has preference over the Company’s common stock and has voting rights equal to that number of shares outstanding, but no conversion or dividend rights. In the event of dissolution or liquidation of the Company, the preferential amount payable to Series C preferred shareholders is $0.55 per share.

Series D Preferred Stock

During 2002, the Board established a Series D preferred stock, authorizing the issuance of up to 2,500,000 shares. The Series D preferred stock has preference over the Company’s common stock but is subordinate to the liquidation preferences of the holders of the Company’s outstanding Series B and Series C preferred stock. Series D preferred stock carries voting rights and is entitled to annual dividends of $0.0235 per share. The dividends are cumulative and payable after payment and satisfaction of the Series B and C preferred stock dividends. No dividends have been declared or paid with respect to the Series D preferred stock. At December 31, 2013, cumulative dividends in arrears on the 1,751,005 outstanding Series D shares were $392,218, payable if and when declared by the Board of Directors. In the event of dissolution or liquidation of the Company, the preferential amount payable to Series D preferred stockholders is $2.50 per share. At December 31, 2013, the liquidation preference for Series D preferred stock was $4,796,731. Holders of the Series D preferred stock have the right, subject to the availability of authorized but unissued common stock, to convert their shares into shares of the Company's common stock on a one-to-one basis without payment of additional consideration and are not redeemable unless by mutual consent. The majority of Series D preferred shares are held by John Lawrence, president of the Company.

We refer you to our Articles of Incorporation, Bylaws and the applicable statutes of the State of Montana for a more complete description of the rights and liabilities of holders of our securities.

General

We may offer and sell our common stock: (a) to one or more underwriters or dealers; (b) through one or more agents; or (c) directly to one or more other purchasers. The common stock offered pursuant to any prospectus supplement may be sold from time to time in one or more transactions at: (i) a fixed price or prices, which may be changed from time to time; (ii) market prices prevailing at the time of sale; (iii) prices related to such prevailing market prices; or (iv) other negotiated prices. We may only offer and sell the common stock pursuant to a prospectus supplement during the period that this prospectus, including any amendments hereto, remains effective. The prospectus supplement for any of the common stock being offered thereby will set forth the terms of the offering of such securities, including the name or names of any underwriters, dealers or agents, the purchase price of such common stock, the proceeds to us from such sale, any underwriting commissions or discounts and other items constituting underwriters’ compensation and any discounts or concessions allowed or re-allowed or paid to dealers. Only underwriters so named in the prospectus supplement are deemed to be underwriters in connection with the securities offered thereby.

By Underwriters

If underwriters are used in the sale, our common stock will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Unless otherwise set forth in the prospectus supplement relating thereto, the obligations of underwriters to purchase the securities will be subject to certain conditions, but the underwriters will be obligated to purchase all of the shares of common stock offered by the prospectus supplement if any of such securities are purchased. We may offer our common stock to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. We may agree to pay the underwriters a fee or commission for various services relating to the offering of any common stock. Any such fee or commission will be paid out of our general corporate funds. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

By Dealers

If dealers are used, and if so specified in the applicable prospectus supplement, we will sell our common stock to the dealers as principals. The dealers may then resell such common stock to the public at varying prices to be determined by such dealers at the time of resale. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time. We will set forth the names of the dealers and the terms of the transaction in the applicable prospectus supplement.

By Agents

Our common stock may also be sold through agents designated by us. Any agent involved will be named, and any fees or commissions payable by us to such agent will be set forth, in the applicable prospectus supplement. Any such fees or commissions will be paid out of our general corporate funds. Unless otherwise indicated in the prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment.

Direct Sales

Common stock may also be sold directly by us at such prices and upon such terms as agreed to by us and the purchaser. In this case, no underwriters, dealers or agents would be involved in the offering.

General Information

Underwriters, dealers and agents that participate in the distribution of our common stock offered by this prospectus may be deemed underwriters under the Securities Act, and any discounts or commissions they receive from us and any profit on their resale of the common stock may be treated as underwriting discounts and commissions under the Securities Act.

Underwriters, dealers or agents who participate in the distribution of securities may be entitled under agreements to be entered into with us to indemnification by us against certain liabilities, including liabilities under United States securities legislation, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof. Such underwriters, dealers or agents may be customers of, engage in transactions with, or perform services for, us in the ordinary course of business.

One or more firms, referred to as “remarketing firms,” may also offer or sell our common stock, if the prospectus supplement so indicates, in connection with a remarketing arrangement upon their purchase. Remarketing firms will act as principals for their own accounts or as agents for us. These remarketing firms will offer or sell the securities in accordance with the terms of the securities. The prospectus supplement will identify any remarketing firm and the terms of its agreement, if any, with us and will describe the remarketing firm’s compensation. Remarketing firms may be deemed to be underwriters in connection with the shares of common stock they remarket.

In connection with any offering of securities, underwriters may over-allot or effect transactions which stabilize or maintain the market price of the common stock offered at a level above that which might otherwise prevail in the open market. Such transactions may be commenced, interrupted or discontinued at any time.
