[{"type":"text","content":"\n\n\n\nDENVER, June 21 /CNW/ -- Vista Gold Corp. (Amex: VGZ; TSX: VGZ) ("Vista")\nis pleased to announce the results of an updated pre-feasibility study for the\nParedones Amarillos gold project in Baja California Sur, Mexico. Vista\nundertook this study to confirm favorable project economics in light of the\nsevere cost inflation which has occurred in the mining sector over the past\nfew years, and in anticipation of making more significant expenditures on the\nproject in 2007. The pre-feasibility study was originally completed for Vista\non September 26, 2005, by Mine Development Associates (MDA) of Reno, Nevada,\nan independent consulting firm, in accordance with Canadian National\nInstrument 43-101 guidelines, under the supervision of Mr. Neil Prenn, P.\nEng., a qualified person, as previously disclosed by Vista in a press release\ndated September 26, 2005. MDA was assisted in the study by Resource\nDevelopment Incorporated (RDi) of Wheat Ridge, Colorado, in metallurgical\ntesting, process redesign, and processing cost estimation, and by WLR\nConsulting (WLR) of Lakewood, Colorado, in mine design. The pre-feasibility\nstudy technical report entitled "Technical Report, Paredones Amarillos\nProject, Baja California Sur, Mexico" dated September 23, 2005, is available\non SEDAR. The current pre-feasibility study prepared for Vista reflects\nmid-2007 costs and economic parameters and was completed on June 20, 2007,\nunder the direction of Mr. Prenn, P. Eng. of MDA, with assistance from RDi.\n\n\nProven and probable mineral reserves, as reported in the September 26,\n2005, press release, were determined in 2005 within a proposed open pit mine,\nwhich was designed employing a Lerchs-Grossmann optimization technique based\non U.S. $400 per ounce gold price and costs prevailing in 2005. The updated\nstudy concluded that the mineral reserves are appropriate as the effects of\ncost inflation are more than offset by higher gold prices. The results, which\nhave not been modified since 2005, are summarized in the following table.\n\n\n Paredones Amarillos Mineral Reserve Estimate*\n (0.38 g/t gold internal cutoff grade)\n\nClassification Gold Grade Waste\n Tonnes (Fire Assay Contained Tonnes Strip Ratio\n (000's) g/t) Gold Ounces (000's) (Waste: Ore)\nProven(1) 11,699 1.11 419,000 -NA- -NA-\nProbable(1) 37,247 0.97 1,...
