Vista Gold Corp. Announces Positive Metallurgical Test Results for the Mt. Todd Project, Northern Territory, Australia, and Appointment of Thomas DeMull as Senior Vice President, Project Development

August 26, 2009

DENVER, Aug. 26 /PRNewswire-FirstCall/ — Vista Gold Corp. (“Vista”) (TSX & NYSE Amex: VGZ) announced today the updated results of metallurgical tests completed for the Mt. Todd gold project, Northern Territory, Australia, and the appointment of Thomas DeMull as Senior Vice President, Project Development.

As part of the on-going engineering studies on the development of the Mt. Todd gold project, Resource Development, Inc. (“RDi”) of Wheat Ridge, Colorado, JKTech Pty Ltd (“JKTech”) of Queensland, Australia, and Ausenco Services Pty Ltd (“Ausenco”) of Perth, Australia, have recently completed additional successful metallurgical test programs and simulations. The metallurgical tests were conducted on core from the 2008 Mt. Todd drilling program that is believed to be representative of approximately 80% of the ore contained in the pit shape identified in Vista’s May 2009 Preliminary Economic Assessment (please refer to Vista’s press release dated June 4, 2009).

The RDi test work confirms a gold recovery of 82% in a whole ore leach circuit with ore that has been ground to a relatively coarse size of 80% passing 100 mesh. JKTech completed testing to determine ore grinding characteristics for both conventional crushing/grinding as well as crushing with high pressure grinding rolls (“HPGR”) followed by grinding. The results of the JKTech testing together with other information were used by Ausenco in a comminution circuit simulation. The work by Ausenco confirmed earlier test work completed by Vista, and indicated energy and operating cost savings may be realized by utilizing HPGR technology for processing the Mt. Todd ore. The results of these studies and simulations will be incorporated into the Preliminary Feasibility Study(2) (“PFS”) which Vista expects to complete in the fourth quarter of this year.

Commenting on the test results, Fred Earnest, Vista’s President and Chief Operating Officer, stated, “The Mt. Todd test program continues to advance, confirming the selection of process technology and developing input parameters for the PFS. The PFS is examining the best approach to develop the estimated 4.25 million ounces of measured and indicated gold resource (147.6 million tonnes at 0.93 g/t)(1,2) and is targeting a potential mining operation with an estimated annual production of approximately 250,000 ounces of gold per year. We are also nearing the completion of a review of exploration data and our initial field programs on the extensive exploration leases, which we will use to design our next exploration program. We believe further drilling on the Batman deposit and on the surrounding exploration leases will define a significantly larger gold resource.”

Additionally, on September 10, 2009, Thomas DeMull will assume the position of Senior Vice President, Project Development. Mr. DeMull holds a MS degree in Metallurgical Engineering from Michigan Technology University and has over 30 years of experience in the development and operation of gold and copper mines. He has worked in North and South America and the Asian-Pacific. Over the past 25 years, Tom has worked on 10 new mine projects, six of which became operating mines, including the Sleeper mine in Nevada and Newmont’s Batu Hijau mine in Indonesia. Most recently, Mr. DeMull held the position of President and CEO of Rocky Mountain Resources Corp.

Fred Earnest, Vista’s President and Chief Operating Officer, stated, “We are very pleased to have an executive with Tom’s qualifications join our team. We believe his talents and experience will allow him to make immediate contributions to our Mt. Todd and Paredones Amarillos development projects.”

About Vista Gold Corp.

Since 2001, Vista has acquired a number of gold projects with the expectation that higher gold prices would increase their value. For more information about our projects, including technical studies and resource estimates, please visit our website at www.vistagold.com. Vista has taken steps to advance the Paredones Amarillos gold project located in Baja California Sur, Mexico, towards production. These steps include the completion of a definitive feasibility study, the purchase of long-delivery processing equipment, and the purchase of land for the processing facilities, related infrastructure and the desalination plant. The results of a Preliminary Economic Assessment completed in 2009 on the Mt. Todd gold project in Australia are encouraging and Vista is undertaking other studies to advance the project, with the completion of a preliminary feasibility study targeted for the fourth quarter of 2009 Vista’s other holdings include the Guadalupe de los Reyes gold project in Mexico, Yellow Pine gold project in Idaho, Awak Mas gold project in Indonesia, and the Long Valley gold project in California.

Todd Gold Project Updated Preliminary Economic Assessment Report, Northern Territory, Australia” dated June 11, 2009 available on SEDAR at www.sedar.com. Mr. John Rozelle, is the independent “qualified person” within the meaning of National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101″) for the mineral resource estimate of the Mt. Todd gold project included in this press release.

(2) Cautionary Note to U.S. Investors concerning estimates of Measured and Indicated Resources: This press release and the PFS and technical report referenced in this press release use the terms “Measured Resources”, “Indicated Resources” and “Measured & Indicated Resources.” We advise U.S. investors that while these terms are defined in and required by Canadian regulations, these terms are not defined terms under the U.S. Securities and Exchange Commission (“SEC”) Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. The PFS and technical report referenced in this press release use the term “inferred resources”. We advise U.S. investors that while this term is defined in and required by Canadian regulations, this term is not a defined term under SEC Industry Guide 7 and is normally not permitted to be used in reports and registration statements filed with the SEC. “Inferred resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. 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 a feasibility study or prefeasibility studies, except in rare cases. The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant “reserves” as in-place tonnage and grade without reference to unit measures. 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.
