DENVER, Feb. 11, 2013 /PRNewswire/ -- Vista Gold Corp. (TSX & NYSE MKT: VGZ) ("Vista" or the "Company") today announced assay results from the final ten holes drilled at the Batman deposit in 2012 as well as the results of the initial exploration hole at the Snowdrop exploration target on the Company's Exploration Licenses at the Mt. Todd gold project in Northern Territory, Australia.

The assay results reported below are from the final ten holes of a 31 core hole drilling program completed in 2011-12. The first 18 holes of the program were incorporated into Vista's updated mineral resource estimate announced September 4, 2012. The last 13 holes, including the ten holes announced today, are anticipated to be incorporated into an updated resource estimate targeted for completion in early March 2013, and used for the planned definitive feasibility study targeted for completion later this year. The Company also continues to advance the Mt. Todd gold project preliminary feasibility study targeted for completion in the first quarter of 2013.   

Frederick H. Earnest, President and CEO of Vista said, "We continue to be pleased by the results of our recent resource conversion drilling program. The drill holes we announced in 2012 focused on resource conversion at the bottom of the economic pit in areas of projected higher grade mineralization. The latter part of the drilling program, including the ten holes announced today, focused on targets on the north and south ends of the economic pit. Based on the results from these holes, we expect there to be a modest increase in measured and indicated resources resulting from the conversion of inferred resources. Furthermore, we believe this will result in positive changes to the project, including improved mine scheduling and better overall economics, without significant changes to the preliminary feasibility study pit designs. We are working with a broad group of independent consultants to finalize the preliminary feasibility study, which we anticipate will be followed by the updated resource estimate and final feasibility study."

The assay results are summarized below.

The orientations of these drill holes relative to the deposit are shown in cross sections found on the Company's web site at http://www.vistagold.com/mt_todd.php?subpage=dr_20130211. The sample intervals are constrained by geology and range from a minimum of 0.2 meters to a maximum of 1.2 meters in length, generally averaging 1 meter in length. Mean grades are calculated at a 0.4 g/t Au cutoff with no upper cap applied. The maximum length of internal waste is 4.0 meters.

Snowdrop Exploration

One core hole was completed on the Snowdrop Target prior to the onset of the wet season. Snowdrop is located approximately 23 kilometers north of the Batman Pit. The target is defined by a soil gold anomaly that is 400 meters long and 200 meters wide. Although the hole did not intersect significant ore grade mineralization, assay results were encouraging and the Company's management believes that additional drilling is warranted. The highest grade intercept was 0.90 g/t Au with six intervals returning greater than 0.4 g/t Au. Three intervals of 31.4 meters, 14.8 meters and 23.3 meters contained detectable (>0.01 g/t) gold. True thicknesses of these intervals are uncertain. Two geochemical signatures are apparent in the assay data; one with gold associated with anomalous base metals and one with an association with As, Bi, Co, and Te.

Additional work is planned correlating gold mineralization with geology and in evaluating recent results from soil and rock chip sampling.

The drilling has been completed and the core has been logged, photographed and sampled by employees or contractors of Vista Gold Australia under the direction 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 prepared and assayed by North Australia Laboratories, Pine Creek, Australia. Second lab check assays were completed by Northern Territory Environmental Laboratories (Intertek Group) in Darwin, Australia. Gold grades are based on a 50 gram fire assay method.

Core logging and sample custody, preparation and assaying were reviewed by Mr. Frank Fenne and Mr. Fenne is of the view that they are sufficient. Mr. Frank Fenne has verified and approved the data and approved the scientific and technical information disclosed in this press release.

Cautionary Note to U.S. Investors Concerning Estimates of Mineral Resources

The United States Securities and Exchange Commission ("SEC") limits disclosure for U.S. reporting purposes to mineral deposits that a company can economically and legally extract or produce. This press release and the technical reports referenced in this press release use the terms "measured resources," "indicated resources," "measured & indicated resources" and "inferred resources." We advise U.S. investors that while these terms are Canadian mining terms as defined in accordance with NI 43-101, and the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") – CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Standards"), such terms are not recognized under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Mineral resources in these categories have a great amount of uncertainty as to their economic and legal feasibility. "Inferred resources" have a great amount of uncertainty as to their existence and, under Canadian regulations, cannot form the basis of a pre-feasibility or feasibility study, except in limited circumstances. 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.

This press release contains forward-looking statements within the meaning of the U.S. Securities Act of 1933, as amended, and U.S. Securities Exchange Act of 1934, as amended, and forward-looking information within the meaning of Canadian securities laws.
