Vista Gold Corp. (Amex: VGZ; TSX: VGZ) is pleased to announce that an updated gold resource estimate for the Batman deposit at the Mt. Todd Gold Project in Northern Territory, Australia was completed on February 26, 2008, by Tetra Tech of Golden, Colorado, in accordance with Canadian National Instrument 43-101 standards. This updated gold resource estimate was completed under the direction of Mr. John Rozelle, P.G., an independent Qualified Person, utilizing standard industry software and resource estimation methodology. The previous resource estimate was originally reported by Vista in a press release dated June 26, 2006. The updated resource estimate incorporates the results of 9,460 assay intervals from 25 drill holes (all core holes) drilled by Vista in 2007 with assaying completed by Northern Australia Labs in Pine Creek and ALS-Chemex in Perth. These results are in addition to the results of 91,225 assay intervals from 730 drill holes (225 core, 435 reverse circulation and 70 rotary drill holes) done by BHP Resources Pty Ltd., Zapopan NL and Pegasus Gold Australia Pty Ltd. used in the previous Mt. Todd resource estimate. Vista has also completed a preliminary evaluation of the development of the project, the results of which were announced in January 2007. For more information on both studies please refer to the Corporation's June 26, 2006 and January 4, 2007 press releases or the Company's website ( for complete studies. A technical report for the updated resource estimate will be filed on SEDAR on or about March 14, 2008.

The new resource estimate as presented in the following table represents an increase in Measured Resources(1) of 769,633 ounces of gold and an increase in Indicated Resources(1) of 367,686 ounces of gold resulting in a combined increase in Measured and Indicated Resources(1) of 1,137,319 ounces of gold at a cutoff grade of 0.50 grams of gold per tonne (0.015 ounces of gold per ton). The gold resource estimate for the Batman deposit as of February 26, 2008, reported at a cutoff grade of 0.015 ounces of gold per ton is set out below. The estimate was prepared using GEMCOM software and used whole block kriging to estimate block values.

  1)  Cautionary Note to U.S. Investors concerning estimates of Measured and
      Indicated Resources: This table uses the terms "measured resources"
      and "indicated resources". We advise U.S. investors that while these
      terms are recognized and required by Canadian regulations, the U.S.
      Securities and Exchange Commission does not recognize them. 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.
  2)  Cautionary Note to U.S. Investors concerning estimates of Inferred
      Resources: This table uses the term "inferred resources". We advise
      U.S. investors that while this term is recognized and required by
      Canadian regulations, the U.S. Securities and Exchange Commission does
      not recognize it. "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. U.S. investors are
      cautioned not to assume that any part or all of an inferred resource
      exists or is economically or legally minable.

Fred Earnest, President and COO of Vista Gold Corp., stated, "The updated resource estimate reflects the success of the 2007 drilling program and the results of a detailed blasthole data study, both of which exceeded our initial expectations. The combined program was successful in three key areas: the conversion of inferred resources to measured or indicated resources, the discovery of new resources at depth and along strike, and improved variography resulting from the analysis of over 158,000 assay intervals in the blasthole database. The drill assay results indicated better gold grades at depth and this is reflected in the new resource model. We plan to undertake a new drilling program in 2008 with the goals of increasing the estimated measured and indicated gold resources and testing the lower areas of the Batman deposit for higher grade mineralization. We intend to complete a preliminary feasibility study later this year which will evaluate significant technical and economic issues and determine what portion of the measured and indicated resources in the Batman deposit could be classified as ore reserves. In the coming months we expect to be able to report the results of other technical studies currently underway. Tetra Tech is estimating the copper resources in the Batman deposit and Resource Development Inc. is completing metallurgical studies to evaluate among other things, the recovery of both copper and gold in a marketable concentrate from the mineralized resources and the effectiveness of high pressure crushing rolls to process the hard mineralized material."

About Mt. Todd

The Mt. Todd Project is situated within the southeastern portion of the Early Proterozoic Pine Creek Geosyncline. The Batman deposit geology consists of a sequence of hornfelsed interbedded greywackes and shales with minor thin beds of felsic tuff. Bedding consistently strikes at 325 degrees, dipping 40 to 60 degrees to the southwest. Northerly trending sheeted quartz sulfide veins and joints striking at 0 to 20 degrees and dipping 60 degrees to the east are the major location for mineralization in the Batman deposit. The veins are 0.04 to 4 inches in thickness with an average thickness of around 0.4 inches and occur in sheets with up to 6 veins per horizontal foot. In general, the Batman deposit is 4,800 to 5,100 feet in length by 1,200 to 1,500 feet in true width and 1,500 to 1,800 feet in known down-dip extension (the deposit is open along strike and at depth).

The deposit has a drill hole spacing that varies from 80 feet by 80 feet to 260-330 feet by 260-330 feet and generally averages 160 feet by 160 feet. All assaying was by fire assay on 50-gram charges with atomic absorption ("AA") finish. It is the opinion of Tetra Tech that quality control and quality assurance methods employed by the various companies working at Mt. Todd were standard at the time of the work. According to Tetra Tech, quality control and quality assurance methods for previous drilling programs has been audited several times by independent consultants.

The 2007 drilling program consisted of 25 core holes resulting in a total of 9,460 assay intervals. As the Qualified Person, Mr. Rozelle reviewed the quality control and quality assurance methods implemented by Vista. Core was logged and cut under the direction of Vista's geologists and half-core segments were sent to independent labs in Pine Creek (Northern Australia Labs) and Perth (ALS-Chemex) for sample preparation and fire assay analysis/AA analysis. Both labs prepared and analyzed a statistically significant number of duplicate samples. In addition to submitting commercially acquired blanks and standards, Vista submitted pulps for re-analysis to the opposing lab. Mr. John Rozelle, P.G., an independent Qualified Person, has reviewed and verified the technical and scientific information contained in this press release.

Vista holds a large exploration land package to the North and East of the Batman deposit and will be undertaking preliminary exploration activities on the prospective land package in 2008. Several localized soil sampling programs were completed prior to the start of the wet season in 2007. Plans are being made for the start of more extensive field mapping and sampling programs with the expectation that conditions in the field will allow the programs to resume in April or May.

About Vista Gold Corp.

Since 2001, Vista has acquired a number of gold projects with the expectation that higher gold prices would significantly increase their value. Vista is undertaking programs to advance the Paredones Amarillos Project, including a definitive feasibility study and the purchase of long delivery equipment items, so that construction can begin during the second half of 2008. The results of a preliminary assessment completed in 2007 on the Mt. Todd Project in Australia were encouraging and additional technical studies are underway with a definitive feasibility study planned for completion by mid-2009. Vista's other holdings include the Guadalupe de los Reyes Project in Mexico, Yellow Pine Project in Idaho, Awak Mas Project in Indonesia, Long Valley Project in California, and Amayapampa Project in Bolivia.
