DENVER, Feb. 27, 2012 /PRNewswire/ --Vista Gold Corp. (TSX & NYSE Amex Equities: VGZ) ("Vista" or the "Company") is pleased to announce additional results for the drilling program currently in progress at its Guadalupe de los Reyes gold-silver project in Sinaloa, Mexico.  Drilling with one drill resumed on January 10, 2012 and a second drill began drilling on January 23, 2012.

Assays have been received from three holes; two from the Guadalupe vein and one from the El Zapote vein. The intercepts from the Guadalupe vein confirm our hypothesis that there is potential for high grade gold-silver mineralization in the district.  Based on the depth of historical underground workings, it is estimated that the intercepts in the Guadalupe vein are a couple hundred meters above the base of the productive zone.  Neither drill hole from the Guadalupe vein reached the planned target depth due to difficult drilling conditions, though, assay results from 12GV-02 indicated strong mineralization at the bottom of the hole.

The results from the first hole in the El Zapote vein are encouraging and confirm the presence of near surface stockwork veining previously defined by reverse circulation drilling.

The results are summarized in the following table.  The equivalent gold grade (Au equiv) was calculated using a metal price ratio of 60:1; 60 g Ag equals 1 g AuEq.

All results are from angle Diamond core holes. Interpreted vein orientation and approximate true width are illustrated on the cross sections on our website. The high grade mineralization intersected in 12GV-02 from 236.3 to 245.2 meters occurs in a brecciated quartz vein and resulted in a lower core recovery (approx. 34%) than has been typically encountered. It is likely that finely ground rock was washed from the core.  The grade of the interval without this loss of material could be lower or higher than reported.  A drill hole location map, together with sections showing the drill hole results and the relationship between the stockwork and low-sulfidation epithermal ("LSE") veins can be found on our website at http://vistagold.com/guadalupe.php?subpage=figures_adr.

Vista's President and CEO, Fred Earnest, stated, "In addition to confirming the results of previous reverse circulation drilling, we are making tremendous advances in validating our hypothesis that the stockwork systems that host the reported estimated mineral resources are underlain by LSE veins with the potential for high gold grades and bonanza silver grades.  We are excited by the success of this drilling program and look forward to the results of drilling on other veins within the district.  These preliminary results (grades and thicknesses) suggest that the LSE veins potentially could be mined by mechanized underground mining methods.  Following the completion of this program in March, we intend to evaluate the overall exploration potential of the district and propose additional drilling in the hope that we can define a high-grade underground mineral resource estimate."

Core was logged, photographed, and sampled by contractors of Vista under the supervision of Vista's Vice President of Exploration, Mr. Frank Fenne P.G., who is a "qualified person" within the meaning of Canadian National Instrument 43-101?Standards of Disclosure for Mineral Projects ("NI 43-101").  Samples were shipped to the ALSChemex sample prep lab in Hermosillo, Mexico.  Prepared sample pulps were shipped by ALSChemex to its assay lab in Vancouver.  Commercial standards and blanks were submitted routinely with each batch of samples.  Gold was analyzed using a 50 gram fire assay with an atomic absorption spectroscopy (AAS) finish.  Silver was initially analyzed using a 41 element ICP analysis using a four acid digestion.  Silver assays greater than 100 g/t were re-assayed using a 50 gram fire assay with a gravimetric finish and these results replaced the AAS finish. An on-going quality control/quality assurance protocol is employed in the program that includes standards and blanks in every batch of assays.  Check assays were conducted on every 20th sample by a second independent laboratory.  Sampling, sample custody, preparation and assaying were completed in compliance with NI 43-101 standards.

Vista has awarded a contract for the completion of a preliminary economic assessment for the Guadalupe de los Reyes gold project to Tetra Tech, Inc.., of Golden, Colorado, and it is anticipated that Tetra Tech, Inc. will complete the study early in the 3rd quarter of 2012.  This study will focus on the economic viability of an open pit mine with a mill to recover gold and silver from the presently reported estimated mineral resources.

Without limiting the foregoing, this press release uses terms that comply with reporting standards in Canada and certain estimates are made in accordance with Canadian National Instrument 43-101 ("NI 43-101"). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosures an issuer makes of scientific and technical information concerning mineral projects.  This press release uses the term "mineral resource." We advise U.S. investors that while the term is recognized by Canadian regulations, the term is not a defined term under the United States Securities and Exchange Commission's (the "SEC") Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Mineral 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 these mineral resources will ever be upgraded to a higher category.  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.  Under SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and all necessary permits and government approvals must be filed with the appropriate governmental authority.  U.S. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into SEC Industry Guide 7 reserves.
