Re:   Registration Statement on Form SB-2
      United States Antimony Corporation Common Stock, Par Value $.01 Per Share

Ladies and Gentlemen:

         We are counsel for United States Antimony Corporation, a Montana
corporation (the "Company"), in connection with the preparation of the
Registration Statement on Form SB-2 (the "Registration Statement") as to which
this opinion is a part, filed with the Securities and Exchange Commission (the
"Commission") on October 25, 2001.

         The Registration Statement relates to the offering by the Selling
Stockholders, as listed in the Registration Statement, of 6,268,065 of common
stock, par value $0.01 per share, of the Company (the "Shares"), of which (i)
2,317,597 shares of common stock issuable upon conversion of debentures at
$0.29125 per share, and 1,682,403 additional shares issuable upon conversion if
the market price is less than $.29125 per share which we are required to
register pursuant to a financing agreement with purchasers of our convertible
debentures; (ii) 1,394,050 shares issuable upon exercise of related warrants at
$0.39 per share; (iii) 150,000 shares of common stock held by a Selling
Shareholder; (iv) 240,343 shares issuable to the holders of debentures as
penalties; and (v) 483,672 shares held by former holders of Series C preferred
stock.

         In connection with rendering our opinion as set forth below, we have
reviewed and examined originals or copies of such corporate records and other
documents and have satisfied ourselves as to such other matters as we have
deemed necessary to enable us to express our opinion hereinafter set forth.

         Based upon the foregoing, it is our opinion that:

                  Based upon such examinations, it is our opinion that (i) the
            Shares (other than the Warrant Shares and the Debenture Shares) are
            validly issued, fully paid and nonassessable and (ii) when there has
            been compliance with the Securities Act of 1933 and the applicable
            state securities laws and when the Warrant Shares and the Debenture
            Shares have been issued, delivered and paid for upon exercise of the
            Warrants or the conversion of the Debentures, as the case may be, in
            accordance with their respective terms, the Warrant Shares and the
            Debenture Shares will be validly issued, fully paid and
            nonassessable.

         The opinions herein are limited to the laws of the State of Texas, the
Montana Business Corporation Act, including the applicable provisions of the
Montana Constitution and reported judicial decisions interpreting these laws and
the federal laws of the United States, and we express no opinion as to the
effect of the matters covered by this opinion of the laws of any other
jurisdiction.

         We hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the prospectus included in the Registration Statement.

Very truly yours,
