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 May 15, 2001.

         The Registration Statement relates to the offering by the Selling
Stockholders, as listed in the Registration Statement, of 5,744,641 shares of
common stock, par value $0.01 per share, of the Company (the "Shares"), of which
(i) 1,394,230 Shares (the "Warrant Shares") are issuable upon the exercise of
certain warrants (the "Warrants") and (ii) 3,716,739 Shares (the "Debenture
Shares") are issuable upon the conversion of certain convertible debentures (the
"Debentures").

         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 Act 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,

/s/Sonfield and Sonfield
