Vista Gold Corp. ("Vista" or the "Company") (TSX & NYSE Amex: VGZ) is pleased to announce the results of a Feasibility Study Update (the "Updated Study") completed by SRK Consulting ("SRK") of Lakewood, Colorado, on the Company's wholly-owned Paredones Amarillos gold project located in Baja California Sur, Mexico.

During the past four months, Vista has undertaken a detailed review of its Paredones Amarillos gold project. The Roberts & Schaefer Company, a large engineering and construction firm based in Salt Lake City, Utah, has reviewed the process facility design to optimize the process area layout, confirmed the proposed production parameters and constructability, and re-estimated the capital and operating costs for the process area. The re-estimated capital and operating costs were incorporated in the Updated Study of the project, which supersedes the economic evaluation reported in the Company's September 8, 2008 press release, in connection with the feasibility study of the Paredones Amarillos gold project (the "Feasibility Study") and the related technical report entitled "Feasibility Study NI 43-101 Technical Report Vista Gold Corp. Paredones Amarillos Gold Project Baja California Sur, Mexico" dated October 20, 2008.

Other cost estimates for the proposed project were reviewed and updated by SRK and incorporated into the Updated Study to reflect current estimated capital and operating cost inputs and commodity prices. The Updated Study estimates a decrease in capital and operating costs and improved project economics. The mineral resources, mineral reserves, mine life and stripping ratios reported in the Feasibility Study remain unchanged. The highlights from the Updated Study compared to the Feasibility Study results are shown in the following table (all currency amounts are in U.S. Dollars):

The Updated Study was prepared by SRK. Terry Braun, P.E., Principal of SRK, an independent "Qualified Person" as defined by Canadian National Instrument 43-101, supervised the preparation of scientific and technical information contained in this press release. The Company anticipates filing the Updated Study on SEDAR and EDGAR within 10 days of this press release.

On August 4, 2009, Vista announced that authorizations had been received for a confirmatory drilling program at the Paredones Amarillos gold project. Drilling started on Friday, August 28, 2009, and Major Drilling de Mexico, S.A. de C.V., under the direction of Vista's exploration team, has completed the first of thirteen holes. Additional metallurgical tests to be undertaken on the new samples from this drilling program are expected to confirm the process plant design criteria and provide additional validation of the mineral reserve model.

Fred Earnest, Vista's President and Chief Operating Officer, stated, "We are very pleased with the results of the Feasibility Study Update for the Paredones Amarillos gold project. The project has been subjected to a detailed and rigorous review of the design criteria and cost assumptions from the Feasibility Study completed in 2008. This effort supports our belief that the project can be built and operated as expected, and we believe that the project continues to represent an attractive investment for Vista as it advances its plan to become a mid-tier gold producer."

Vista's advisors continue to work with Mexican authorities to expedite the approval of the Temporary Occupation Permit and the Change of Land Use Permit for the Paredones Amarillos gold project. Mr. Earnest commented, "The review process continues to advance favourably and we anticipate the approval process to reach a successful conclusion in the near future. We have also initiated a community engagement program in anticipation of receiving the permits. We expect this program to involve several different workshops and meetings over the course of the next 3-4 months as we work with the local communities and stakeholders to ensure the successful development of the Paredones Amarillos gold project."

All mineral reserves and resources have been estimated in accordance with the definition standards on mineral resources and mineral reserves of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in National Instrument 43-101, commonly referred to as NI 43-101. U.S. reporting requirements for disclosure of mineral properties are governed by the United States Securities and Exchange Commission (SEC) Industry Guide 7. Canadian and Guide 7 standards are substantially different and the information contained in this press release, the Updated Study and the Feasibility Study are not comparable to similar information disclosed by U.S. companies. This press release, the Updated Study and the Feasibility Study referenced in this press release use the terms "measured," "indicated," and "inferred" resources. We advise investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. Inferred mineral resources are considered too speculative geologically to have economic considerations applied to them that enable them to be categorized as mineral reserves. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. U.S. investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally minable. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves.
