PROSPECTUS SUPPLEMENT

(To Prospectus dated January 31, 2022)

United States Antimony Corporation

Up to $25,000,000

Common Stock

We have entered into a Sales Agreement, or sales agreement, with A.G.P./Alliance Global Partners, A.G.P. or the Agent, relating to shares of our common stock, $0.01 par value per share, offered by this prospectus supplement and the accompanying prospectus. Pursuant to this prospectus supplement and accompanying prospectus, from time to time we may offer and sell shares of our common stock having an aggregate gross proceeds of up to $25,000,000 through or to the Agent, acting as sales agent or principal.

Our common stock is listed on the NYSE American under the symbol "UAMY." The last reported sale price of our common stock on November 5, 2024 was $0.60 per share.

Sales of our common stock, if any, under this prospectus supplement may be made in sales deemed to be an "at the market offering" as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended, or the Securities Act. Subject to terms of the sales agreement, the Agent is not required to sell any specific number or dollar amounts of securities but will act as our sales agent using commercially reasonable efforts consistent with their normal trading and sales practices, on mutually agreed terms between the Agent and us. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.

As of November 5, 2024, we had 21,306,468 authorized but unissued shares of our common stock available for issuance (after deducting the number of shares outstanding and reserved for issuance). Based on 21,306,468 authorized shares of common stock available for issuance and an assumed offering price per share of $0.60, which was the last reported sale price of our common stock on the NYSE American on November 5, 2024, we would be able to issue and sell shares under the Sales Agreement for a maximum of approximately $12,783,881. Our shareholders approved increasing our authorized shares at the discretion of our Board of Directors at our annual shareholders meeting on July 30, 2024 from 150 million shares to 250 million shares. Our Board of Directors will increase our authorized shares if needed and advisable in order to allow for the sale of the $25,000,000 maximum aggregate offering amount set forth in this prospectus supplement, which is subject to the filing and effectiveness of an amendment to our Third Restated Articles of Incorporation. In no event will we sell, pursuant to the registration statement of which this prospectus supplement forms a part, more shares than we have available and authorized for issuance.

i

The Agent will be entitled to compensation under the terms of the sales agreement at a fixed commission rate of up to 3.0% of the gross sales price per share sold. In connection with the sale of our common stock on our behalf, the Agent will each be deemed to be an "underwriter" within the meaning of the Securities Act and the compensation of the Agent will be deemed to be underwriting commissions or discounts. We have also agreed to provide indemnification and contribution to the Agent against certain civil liabilities, including liabilities under the Securities Act. See "Plan of Distribution" beginning on page S-12 for additional information regarding the compensation to be paid to the Agent.

Investing in our common stock involves risks. See "Risk Factors" on page S-7 of this prospectus supplement and in the documents incorporated by reference into this prospectus supplement and the accompanying prospectus before investing in our common stock.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

A.G.P.

The date of this prospectus supplement is November 12, 2024.

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights selected information contained elsewhere in this prospectus supplement, the accompanying prospectus and any free writing prospectus and in the documents we incorporate by reference herein and therein. This summary does not contain all of the information you should consider before investing in our common stock. You should read this entire prospectus supplement and the accompanying prospectus, including the documents incorporated by reference herein and therein, carefully, especially the risks of investing in our common stock discussed under "Risk Factors" beginning on page S-7 of this prospectus supplement and the "Risk Factors" section of our most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q .

Overview of the Company

We sell processed antimony, zeolite, and precious metals products primarily in the U.S. and Canada. The Company processes antimony ore primarily into antimony oxide, antimony metal, and antimony trisulfide. Our antimony oxide is used to form a flame-retardant system for plastics, rubber, fiberglass, textile goods, paints, coatings and paper, as a color fastener in paint, and as a phosphorescent agent in fluorescent light bulbs. Our antimony metal is used in bearings, storage batteries, and ordnance. Our antimony trisulfide is used as a primer in ammunition. In its operations in Idaho, the Company mines and processes zeolite, a group of industrial minerals used in soil amendment and fertilizer, water filtration, sewage treatment, nuclear waste and other environmental cleanup, odor control, gas separation, animal nutrition, and other miscellaneous applications. We recover certain amounts of precious metals, primarily gold and silver, at our plant in Montana from antimony concentrates.

Implications of Being a Smaller Reporting Company

We are a "smaller reporting company" as defined in the Securities Exchange Act of 1934, as amended, or the Exchange Act.

RISK FACTORS

Investing in our common stock involves a high degree of risk. Before investing in our common stock, you should consider carefully the risks described below and under the heading "Risk Factors" in our most recent Annual Report on Form 10-K, as well as any amendment or update to our risk factors reflected in subsequent filings with the SEC, which are incorporated by reference into this prospectus supplement, together with the other information contained in this prospectus supplement, the accompanying prospectus and in our other filings with the SEC that we have incorporated by reference in this prospectus supplement and the accompanying prospectus. If any of these risks occur, our business, financial condition, results of operations and future growth prospects could be materially and adversely affected. In these circumstances, the market price of our common stock could decline, and you may lose all or part of your investment.

Risks Related to this Offering

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of common stock or other securities convertible into or exchangeable for our common stock at prices that may not be the same as the price per share in this offering, which could include warrants or preferred stock. We may sell shares or other securities in any other offering at a price per share that is less than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into common stock, in future transactions may be higher or lower than the price per share paid by investors in this offering.

You may experience immediate and substantial dilution in the book value per share of the common stock you purchase.

Because the prices per share at which shares of our common stock are sold in this offering may be substantially higher than the book value per share of our common stock, you may suffer immediate and substantial dilution in the net tangible book value of the common stock you purchase in this offering. The shares sold in this offering, if any, will be sold from time to time at various prices. After giving effect to the sale of our common stock in the maximum aggregate offering amount of $25,000,000 at an assumed offering price of $0.60 per share, which was the last reported sale price of our common stock on the NYSE American on November 5, 2024, and after deducting estimated offering commissions and expenses payable by us, our net tangible book value of our continuing and discontinued operations as of September 30, 2024 would have been approximately $49,464,799, or $0.33 per share of common stock. This represents an immediate dilution of $0.27 in net tangible book value per share to purchasers of our common stock in this offering and an immediate accretion in as-adjusted net tangible book value of approximately $0.10 per share to our existing stockholders. See "Dilution" below for a more detailed discussion of the dilution you may incur in connection with this offering.

We have broad discretion in the use of our cash and cash equivalents, including the net proceeds we receive in this offering, and may not use them effectively.

Our management has broad discretion to use our cash and cash equivalents, including the net proceeds we receive in this offering, to fund our operations and could spend these funds in ways with which you may not agree or in ways which do not improve our results of operations or enhance the value of our common stock. See "Use of Proceeds". The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business, cause the price of our common stock to decline. Pending their use to fund our operations, we may invest our cash and cash equivalents, including the net proceeds from this offering, in a manner that does not produce income or that loses value.

S-7

Table of Contents

The common stock offered hereby will be sold in "at the market offerings" and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices, and accordingly may experience different levels of dilution and different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices and number of shares sold in this offering. Investors may experience a decline in the value of the shares they purchase in this offering as a result of sales made at prices lower than the prices they paid.

The actual number of shares we will issue under the sales agreement, at any one time or in total, is uncertain.

Subject to certain limitations in the sales agreement and compliance with applicable law, we have the discretion to deliver a placement notice to the Agent at any time throughout the term of the sales agreement. The number of shares that are sold by the Agent after delivering a placement notice will fluctuate based on the market price of our common stock during the sales period and limits we set with the Agent. Because the price per share of each share sold will fluctuate based on the market price of our common stock during the sales period, it is not possible at this stage to predict the number of shares that will be ultimately issued.

As of November 5, 2024, we had 21,306,468 authorized but unissued shares of our common stock available for issuance (after deducting the number of shares outstanding and reserved for issuance). Based on 21,306,468 authorized shares of common stock available for issuance and an assumed offering price per share of $0.60, which was the last reported sale price of our common stock on the NYSE American on November 5, 2024, we would be able to issue and sell shares under the Sales Agreement for a maximum of approximately $12,783,881. Our shareholders approved increasing our authorized shares at the discretion of our Board of Directors at our annual shareholders meeting on July 30, 2024 from 150 million shares to 250 million shares. Our Board of Directors will increase our authorized shares if needed and advisable in order to allow for the sale of the $25,000,000 maximum aggregate offering amount set forth in this prospectus supplement, which is subject to the filing and effectiveness of an amendment to our Third Restated Articles of Incorporation. In the event we do not file an effective amendment to our Third Restated Articles of Incorporation, we will be unable to effect the sale of the $25,000,000 maximum aggregate offering amount set forth in this prospectus supplement.

Resales of our common stock in the public market by our stockholders during this offering may cause the market price of our common stock to fall.

We may issue shares of common stock from time to time in connection with this offering. The issuance from time to time of these new shares of common stock, or our ability to issue new shares of common stock in this offering, could result in resales of our shares of common stock by our current stockholders concerned about the potential dilution of their holdings. In turn, these resales could have the effect of depressing the market price for our common stock.

Sales of a substantial number of shares of our common stock, or the perception that such sales may occur, may adversely impact the price of our common stock.

Sales of a substantial number of shares of our common stock in the public markets could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our common stock would have on the market price of our common stock.

USE OF PROCEEDS

We may issue and sell shares of our common stock having aggregate gross sales proceeds of up to $25,000,000 from time to time (before deducting sales agent commissions and expenses). Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time.

We may use the net proceeds of this offering, if any, for general corporate purposes, including working capital, inventory, personnel, operating expenses and capital expenditures for both our Zeolite and Antimony Divisions. We may also use the net proceeds to acquire or invest in businesses and products that are complementary to our own. In addition, we may use the net proceeds to purchase mining claims and the related capital infrastructure to sell mineral products to various industries or government agencies.

This expected use of net proceeds from this offering represents our intentions based upon our current plans and business conditions, which could change in the future as our plans and business conditions evolve. The amounts and timing of our actual use of the net proceeds may vary significantly depending on numerous factors, any unforeseen cash needs. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. Accordingly, our management will have broad discretion in the timing and application of these proceeds.

DILUTION

If you invest in our common stock, your interest will be diluted immediately to the extent of the difference between the public offering price per share and the adjusted net tangible book value per share of our common stock after this offering. Our net tangible book value of our continuing and discontinued operations at September 30, 2024, was approximately $25,127,049, or $0.23 per share, based on 108,438,984 shares of our common stock then outstanding. Net tangible book value per share is equal to our total tangible assets, less our total liabilities, divided by the total number of shares outstanding as of September 30, 2024.

After giving effect to the sale of our common stock in this offering in the aggregate amount of $25,000,000 at an assumed offering price of $0.60 per share, the last reported sale price of our common stock on the NYSE American on November 5, 2024, and after deducting commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value as of September 30, 2024 would have been approximately $49,464,799, or $0.33 per share of common stock. This represents an immediate increase in pro forma net tangible book value of $0.10 per share to our existing stockholders and an immediate dilution in pro forma net tangible book value of $0.27 per share to new investors in this offering. Dilution per share to new investors in this offering is calculated as the difference between the assumed public offering price per share and the pro forma as adjusted net tangible book value per share after this offering.

The following table illustrates this calculation on a per share basis. The as adjusted information is illustrative only and will adjust based on the actual price to the public, the actual number of shares sold and other terms of the offering determined at the time shares of our common stock are sold pursuant to this prospectus supplement.

Assumed public offering price per share					$	0.60
Net tangible book value per share as of September 30, 2024		$	0.23
Increase in pro forma net tangible book value per share after this offering		$	0.10
Pro forma as adjusted net tangible book value per share after giving effect to this offering						$	0.33
Dilution per share to new investors participating in this offering						$	0.27

The common stock outstanding after the offering is based on 108,438,984 shares of our common stock outstanding as of September 30, 2024, and excludes, as of September 30, 2024:

	·	7,908,333 outstanding stock options and restricted stock units, or RSUs (which includes unvested stock options and RSUs) and shares reserved for issuance under our Equity Incentive Plan;

DIVIDEND POLICY

We have never declared dividends or paid cash dividends on our capital stock. Our board of directors will make any future decisions regarding dividends. We currently intend to retain and use any future earnings for the development and expansion of our business and we do not anticipate paying any cash dividends in the near future. Our board of directors has complete discretion on whether to pay cash dividends. Even if our board of directors decides to pay additional dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant.

PLAN OF DISTRIBUTION

We have entered into the sales agreement with A.G.P., dated November 12, 2024, under which we may issue and sell our common stock from time to time through or to the Agent acting as sales agent or principal. The form of the sales agreement was filed as an exhibit to our Quarterly Report on Form 10-Q for the quarter ended September 30, 2024 and is incorporated by reference in this prospectus supplement. See the "Where You Can Find More Information" section of this prospectus supplement. Sales of shares of our common stock, if any, under this prospectus supplement and the accompanying prospectus may be made by any method that is deemed an "at the market offering" as defined in Rule 415 promulgated under the Securities Act.

We may instruct the Agent not to sell common stock if the sales cannot be effected at or above the price designated by us from time to time. We or the Agent may suspend the offering of common stock upon notice and subject to other conditions. The Agent will offer our common stock subject to the terms and conditions of the sales agreement as agreed upon by us and the Agent. Each time we wish to issue and sell common stock under the sales agreement, we will notify the Agent of the number or dollar value of shares to be issued, the time period during which such sales are requested to be made, any limitation on the number of shares that may be sold in one day, any minimum price below which sales may not be made and other sales parameters as we deem appropriate. Once we have so instructed the Agent, unless the Agent declines to accept the terms of the notice, the Agent has agreed to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such shares up to the amount specified on such terms. The obligations of the Agent under the sales agreement to sell our common stock are subject to a number of conditions that we must meet.

We will pay the Agent commissions for its services in acting as agent in the sale of common stock at a commission rate equal to up to 3.0% of the gross sales price per share sold. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We have also agreed to reimburse the Agent for certain specified expenses, including the fees and disbursements of its legal counsel in an amount not to exceed $60,000, plus up to $10,000 per calendar quarter for ongoing diligence arising from the transactions contemplated by the sales agreement. We estimate that the total expenses for the offering, excluding commissions and reimbursements payable to the Agent under the terms of the sales agreement, will be approximately $154,750.

Settlement for sales of common stock will generally occur on the first trading day following the date on which any sales are made, or on some other date that is agreed upon by us and the Agent in connection with a particular transaction, in return for payment of the net proceeds to us. Sales of our Common Stock as contemplated in this prospectus will be settled through the facilities of The Depository Trust Company or by such other means as we and the Agent may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

In connection with the sale of the common stock on our behalf, the Agent will be deemed to be an "underwriter" within the meaning of the Securities Act and the compensation of the Agent will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to the Agent against certain civil liabilities, including liabilities under the Securities Act.

This offering of our common stock pursuant to this prospectus will terminate upon the earlier of (i) the sale of all of our common stock subject to this prospectus, or (ii) termination of the sales agreement as provided therein.

The Agent and its affiliates may in the future provide various investment banking and other financial services for us and our affiliates, for which services they may in the future receive customary fees. In the course of its business, the Agent may actively trade our securities for its own account or for the accounts of customers, and, accordingly, the Agent may at any time hold long or short positions in such securities. To the extent required by Regulation M, the Agent will not engage in any market making activities involving our common stock while the offering is ongoing under this prospectus supplement.

This prospectus supplement in electronic format may be made available on a website maintained by the Agent, and the Agent distribute this prospectus supplement and the accompanying prospectus electronically.
