Vista Gold Corp. Announces New Exploration Target Discovery at its Mt. Todd Gold Project and Provides Mt. Todd Gold Project Update

DENVER, June 29 /PRNewswire-FirstCall/ -- Vista Gold Corp. ("Vista" or the "Company") (TSX & NYSE Amex Equities: VGZ) announced today the discovery of a new exploration target located on its Exploration Tenements held together with the Mining Leases at the Company's Mt. Todd gold project in Northern Territory ("NT"), Australia. Vista also provided updates on the progress of a drilling program at the Batman deposit and announced that the Pre-Feasibility Study for the Mt. Todd gold project is nearing completion.

New Exploration Target Discovery

Vista controls a large land package (160,878 hectares) of Exploration Tenements surrounding the Mt. Todd gold project. As part of a comprehensive exploration effort based on results from an airborne magnetic survey and geochemical soil sampling by the Company, Vista's geologists have identified four new gold bearing zones for potential follow up with additional sampling and testing.  Of note, at the target identified as MSTS-4, rock chip sampling in an area with limited exposure, returned a 25.0 g/t gold sample from a small outcrop of fault breccia.  Follow-up sampling returned 23.0 g/t and 7.7 g/t gold assays in vein and breccias located 15 meters and 50 meters, respectively, north of the original sample.   Due to the sparse outcrop, the orientation and thickness of the mineralized zone is not currently known, but Vista's management believes that these initial results are significant, and together with historically identified exploration targets support the potential for development of additional resources at the Mt. Todd gold project.  Further mapping and sampling is in progress and multi-element analysis results are pending.  Samples were collected by employees of Vista Gold Australia and analysis was completed by Northern Australian Laboratories in Pine Creek, NT.  The Company plans to conduct reverse circulation drilling in the area of this new discovery and the other targets later this year.

Batman Deposit Drilling Update

As previously announced, the Company undertook an additional drilling program at the Batman deposit at the Mt. Todd gold project.  The Company has now completed 14 core and six reverse circulation drill holes (8,291 total meters drilled) in a program designed to add resources through in-fill drilling in the parallel structures to the east of the core zone of the Batman deposit, to test/condemn hypothesized extensions of the deposit along strike and to the west of the core zone, and to provide core for metallurgical testing.  The program concluded with the in-fill drilling of the parallel structures on the east of the Batman deposit.  Assays have not yet been completed for the last holes of the program.  The drill holes were oriented to the west to intersect the core zone at right angles and were inclined at -55 to -60 degrees.  

Vista also drilled three core holes totaling 1,469 meters, that were located and oriented to provide core samples for metallurgical testing, representative of the Batman deposit, in the area of the pit defined by the June 2009 Mt. Todd Preliminary Economic Assessment ("PEA").  The holes were drilled at -20 to -30 degree dips, at an acute angle to the strike of the deposit and were not assayed due to the requirements for whole core to be used in the planned metallurgical testing program.

The drilling has been completed and the core has been logged, photographed and sampled by employees 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").  Core to be assayed has been shipped to ALS-Chemex sample prep lab in Alice Springs, Australia.  Prepared sample pulps are shipped by ALS-Chemex to its assay lab in Perth, Australia.  Core logging and sample custody, preparation and assaying were completed in compliance with NI 43-101 standards.

Mt. Todd Gold Project Pre-Feasibility Study Update

The Company also announced that it continues to advance its Pre-Feasibility Study ("PFS") for the Mt. Todd gold project and that the PFS is expected to confirm the principal metallurgical parameters used in the positive PEA for the Mt. Todd gold project announced in June 2009 and updated in August 2009.  As previously announced, the completion of the PFS has been delayed to allow additional engineering work in the areas of power generation/supply, tailings disposal/storage and the supply of lime for process and water treatment needs.   The Company expects to complete the PFS and announce its results in the third quarter of this year.  

The Company further announced that it has notified the Government of the Northern Territory that, based on its on-going positive results at the Mt. Todd gold project, the Company intends to extend its agreement with the Northern Territory Government related to the Mt. Todd gold project for an additional five-year period ending at the end of 2015.  

Tetra Tech Inc. of Golden, Colorado, is contracted to manage and prepare the PFS in accordance with NI 43-101.  The PEA was prepared under the direction of Mr. John Rozelle, an independent qualified person under NI 43-101.  The results of the PEA are outlined in a NI 43-101 technical report entitled "Mt. Todd Gold Project Updated Preliminary Economic Assessment Report, Northern Territory, Australia" and is dated June 11, 2009.  The PEA is available on SEDAR at www.sedar.com. John Rozelle is the independent "qualified person", within the meaning of NI 43-101, who supervised the preparation of the scientific and technical information contained in this press release.

All mineral reserves and resources in this press release and in the PEA referenced in this press release have been estimated in accordance with the definition standards on mineral resources and mineral reserves of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in National Instrument 43-101,  U.S. reporting requirements for disclosure of mineral properties are governed by the United States Securities and Exchange Commission (SEC) Industry Guide 7. Canadian and Guide 7 standards are substantially different and the information contained in this press release and the PEA are not comparable to similar information disclosed by U.S. companies  This press release and the PEA referenced in this press release use the terms "measured," "indicated," and "inferred" resources. We advise investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. Inferred mineral resources are considered too speculative geologically to have economic considerations applied to them that enable them to be categorized as mineral reserves. 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 feasibility or pre-feasibility studies, except in rare cases. U.S. investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally minable. 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.
