DENVER, April 19, 2012 /PRNewswire/ -- Vista Gold Corp. (TSX & NYSE Amex Equities: VGZ) (" Vista" or the " Corporation") is pleased to announce that it filed today a final short form base shelf prospectus with the securities commissions in each province and territory of Canada (other than Quebec) and that its shelf registration statement on Form S-3 filed with the United States Securities and Exchange Commission was brought effective (collectively, the " Offering Documents"). The Offering Documents were filed to replace Vista's prior Canadian short form base shelf prospectus that expired last year and Vista's current shelf registration statement on Form S-3 that expires in the second quarter of this year. The Offering Documents preserve Vista's ability to complete future financings for corporate growth and development in an efficient and flexible manner, if appropriate at the time. The Offering Documents allow Vista to make offerings of common shares, warrants, subscription receipts or units for aggregate proceeds of up to US$200 million during the next three years to potential purchasers in the United States and, upon issuance of a receipt by the applicable Canadian securities regulators, during the next 25 months to potential purchasers in each province and territory of Canada (other than Quebec). As previously announced, Vista currently anticipates using any proceeds from the sale of securities under the Offering Documents, if any, to fund the development of existing or acquired mineral properties and may also use such funds for acquisitions, working capital requirements, to repay indebtedness outstanding from time to time or for other general corporate purposes. The terms of any securities offered under the Offering Documents and the intended use of the net proceeds resulting from such offering will be established at the time of any offering and will be described in a prospectus supplement filed with the United States Securities and Exchange Commission and the applicable Canadian securities regulatory authorities at the time of the offering. A copy of the Offering Documents and, at the time of an offering, if any, a prospectus supplement relating to the offering under the Offering Documents, when available, can be obtained by contacting Vista, attention: Connie Martinez at (720) 981-1185, Suite 5, 7961 Shaffer Parkway, Littleton, Colorado 80127.
