[{"type":"text","content":"\n\n\nDENVER, May 22, 2013 /CNW/ -- Vista Gold Corp. (\"Vista\" or the \"Company\") (NYSE MKT and TSX: VGZ) today published the significant results of feasibility-level metallurgic test work supporting the comminution circuit design and estimated gold recovery rates for the Batman deposit at the Mt. Todd gold project in Northern Territory, Australia. The test work was based on HQ core samples from the Company's 2011 and 2012 drilling programs and included extensive variability testing. This test work, combined with the findings of previous test work programs, supports (1) ore hardness estimates at the Batman deposit that are consistent and do not change at depth; (2) the selection of High Pressure Grinding Roll (\"HPGR\") technology as part of the comminution circuit; (3) gold recovery rates for freshly mined ore of 81.7% based on optimized grind size and leach conditions; and (4) the processing of material from the historic heap leach pad at the end of the proposed mine life. Results of this test work are being incorporated into the Company's preliminary feasibility study (\"PFS\"), the results of which will be released prior to market open on May 29, 2013. Vista will host a conference call that afternoon to discuss the results of the PFS.\nVista's President and Chief Executive Officer, Frederick H. Earnest, commented, \"These metallurgic test results are key milestones in the optimization of the Mt. Todd gold project. Since purchasing the project in 2006, Vista has completely re-evaluated the entire project with a methodical, systematic and exhaustive focus on the metallurgical process. The feasibility-level metallurgic testing program has added significantly to our understanding of the metallurgical behavior of the Batman deposit and independently validated more than six years of technical analysis of the project. We are confident that material from the Batman deposit can be efficiently processed by proven, 'off the shelf' technologies to achieve good gold recoveries.\"\nFull technical reports are available under the \"Technical Reports\" header of the Mt.
