The increasing management demands of developing three major projects necessitate the change and will allow me to focus on potential growth and value-adding opportunities for the Corporation."

About Vista Gold Corp.

Since 2001, Vista has acquired a number of discovered gold projects with the expectation that higher gold prices would significantly increase their value. As gold prices have risen, Vista has completed various preliminary evaluations that have demonstrated that some of the projects would be potentially viable operations at today's gold prices. Currently, Vista is undertaking technical programs to bring the most advanced projects to the point where decisions can be made to put these projects into production, either by Vista, or through sale or joint venture to other mining companies. Vista's holdings include the Paredones Amarillos and Guadalupe de los Reyes Projects in Mexico, Mt. Todd Project in Australia, Yellow Pine Project in Idaho, Awak Mas Project in Indonesia, Long Valley Project in California, and the Amayapampa Project in Bolivia.
