The information in this prospectus supplement concerning the selling security holders supersedes in part the information set forth under the caption "Selling Security Holders" in the prospectus by deleting the information contained in the table regarding the selling security holders with respect to beneficial ownership of our common shares, as well as the paragraph immediately preceding that table, and substituting therefor the following paragraphs and table: On September 19, 2002, as discussed in the prospectus, the SEC declared effective the registration statement of which this prospectus forms a part. As a consequence, all of our $2,774,000 principal amount of convertible debentures were automatically converted, pursuant to their terms, into debenture units at a price of $1.026 per debenture unit. Each debenture unit consisted of one common share and one 5-year warrant entitling the holder to purchase one common share at a price of $1.50. Reflecting prior conversions of some of the convertible debentures, we issued 2,485,370 common shares and the same number of warrants as of the effective date of the registration statement. The following table sets forth, as of the date of this prospectus supplement, the number of shares being held of record or beneficially by the selling security holders as well as the remaining number of shares that may be offered under this prospectus, and provides by footnote reference any material relationship between Vista Gold and the selling security holder, all of which is based upon information currently available to us. ----------------------------------------------------------------------------------------------------------------------- Beneficial Ownership of Beneficial Ownership of Selling Security Holder Shares As of Date of Prospectus Supplement (1) After Offering (2) --------------------------------------- ------------------ ----------------------------------------------------------------------------------------------------------------------- Remaining Number of Shares Offered Hereby Name of Selling Security Holder Number Percent (3) Number Percent ------------------------------- ------ ------- --- ------ ------- ----------------------------------------------------------------------------------------------------------------------- Quest Investment Corporation (4) 1,666,800 (5) 16.2% 1,666,800 (5) 0 * ----------------------------------------------------------------------------------------------------------------------- Global Resource Investments Ltd.
