Vista Gold Corp. (Amex: VGZ; TSX) announces that it has agreed with Luzon Minerals Ltd. (TSX: LU), subject to regulatory approval, to further amend certain of the terms of the purchase option agreement between the companies concerning Vista's Amayapampa gold project in Bolivia. The agreement was most recently amended in July 2005, as previously announced.

The agreement as amended on July 18, 2005, as previously reported, called for an aggregate purchase price comprising: U.S. $2,700,000 (including U.S. $100,000 previously paid); either 3,250,000 or 4,250,000 common shares in the capital of Luzon (including 250,000 already issued to Vista); 1,000,000 common share purchase warrants; and a net smelter return royalty.

  The following amendments have been approved:

   *  The number of Luzon common share warrants to be issued has been
      increased from 1,000,000 to 1,500,000, the exercise price has been
      reduced from CDN $0.20 to CDN $0.15, and the exercise period has been
      reduced from three to two years from the date of issuance.  As well,
      the new agreement now provides that if the closing trading price of
      Luzon common shares equals or exceeds CDN $0.25 for 20 consecutive
      trading days, Luzon may request that Vista exercise the warrants, in
      which case the exercise period would conclude 15 business days
      following the request.

   *  Vista has agreed to defer a U.S. $100,000 cash payment from Luzon
      from the earlier of December 31, 2005 or the date of the closing of
      the next debt, equity or other financing completed by Luzon until the
      earlier of December 1, 2006 or the date Luzon completes or obtains
      financing sufficient to commence construction at the Amayapampa

  Other terms of the agreement remain unchanged.

Mike Richings, Vista President and CEO, stated "We are pleased with the progress that the new management at Luzon is making with the Amayapampa Project. We believe these amendments will facilitate their efforts to advance Luzon and the development of the project."
