Vista Gold Corp. Reports Assay Results for Ongoing Resource Conversion Drilling Program at the Mt. Todd Gold Project

DENVER, July 12, 2012 /CNW/ - Vista Gold Corp. (TSX & NYSE MKT: VGZ) ("Vista" or the "Company") today announced assay results of drill holes from the ongoing resource conversion drilling program at the Mt. Todd gold project in Northern Territory, Australia.

Vista has now completed 19 holes totaling 13,047 meters. The assay results of the first ten holes (approximately 50% of total drilled to-date) were announced previously (please refer to our press releases dated March 12, April 25, and June 5, 2012). The following table summarizes results from the subsequent three holes.

The orientation of these drill holes relative to the deposit is shown in cross sections found on the Company's web site at http://vistagold.com/mt_todd_test.php?subpage=dr_20120712. 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 grams/tonne Au cutoff with no upper cap applied. The maximum length of internal waste is 4.0 meters.

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.

Vista's President and Chief Executive Officer, Fred Earnest, commented, "The latest assay results, from holes drilled on both the north and south sides of the Batman deposit, continue to confirm our understanding of the deposit. Consistent with previous results from this drilling program, the mineralized intercepts are being encountered where predicted and are returning assay results generally better than the estimated grade of corresponding blocks in the current resource model. A review of the drilling program results as shown on the cross sections on our web site further supports both our expectation that we will increase the estimated measured and indicated resources at the Mt. Todd project, as well as our decision to incorporate a larger processing facility into the project's feasibility study."

About Vista Gold Corp.

Vista is advancing exploration on its Guadalupe de los Reyes gold/silver project in Mexico and has granted Invecture Group, S.A. de C.V. a right to earn a 62.5% interest in the Concordia gold project in Mexico.

This press release uses the terms "measured resources," "indicated resources," and "measured & indicated resources." We advise U.S. investors that while these terms are Canadian mining terms as defined in 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 definitions differ from the definitions in 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 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 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. All statements, other than statements of historical facts, included in this press release that address activities, events or developments that Vista expects or anticipates will or may occur in the future, including such things as, estimates of mineral resources, the conversion of resources to measured and indicated resources, the decision to incorporate a larger process facility and the potential impact thereof and other such matters are forward-looking statements and forward-looking information. The material factors and assumptions used to develop the forward-looking information and the forward-looking information contained in this press release include the following: results of feasibility studies, mineral resource and reserve estimates, exploration and assay results, terms and conditions of our agreements with contractors and our approved business plan. When used in this press release, the words "optimistic," "potential," "indicate," "expect," "intend," "hopes," "believe," "may," "will," "if," "anticipate," and similar expressions are intended to identify forward-looking statements and forward-looking information. These statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of Vista to be materially different from any future results, performance or achievements expressed or implied by such statements. Such factors include, among others, uncertainty of resource estimates, estimates of results based on such resource estimates; risks relating to completing metallurgical testing; risks relating to cost increases for capital and operating costs; risks relating to delays in the completion of anticipated drilling activities at the Mt. Todd gold project, risks related to the timing and the ability to obtain the necessary permits, risks of shortages and fluctuating costs of equipment or supplies; risks relating to fluctuations in the price of gold; the inherently hazardous nature of mining-related activities; potential effects on Vista's operations of environmental regulations in the countries in which it operates; risks due to legal proceedings; risks relating to political and economic instability in certain countries in which it operates; as well as those factors discussed under the headings "Note Regarding Forward-Looking Statements" and "Risk Factors" in Vista's Amendment No. 1 to its Annual Report on Form 10-K as filed on April 5, 2012 and other documents filed with the U.S. Securities and Exchange Commission and Canadian securities regulatory authorities. Although Vista has attempted to identify important factors that could cause actual results to differ materially from those described in forward-looking statements and forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. Except as required by law, Vista assumes no obligation to publicly update any forward-looking statements or forward-looking information; whether as a result of new information, future events or otherwise.
