Calvista Gold Updates on Its Property Acquisition in the California Valley

TORONTO, ONTARIO--(Marketwire - Dec. 21, 2011) - Calvista Gold Corporation (TSX:CVZ) ("Calvista" or the "Company") updates as a follow up to its August 23, 2011 press release (the "August Release"), that Ingeominas, Colombia's mining authority, by Resolution GTRB-0208 dated December 15, 2011, transferred a 60% interest in License 090-98 (El Carmen) (the "Subject Property") to Calvista's wholly owned subsidiary Sociedad Minera Calvista Colombia, S.A.S. ("Calvista Colombia"). Transfer of the remaining 40% in the Subject Property is already in progress and is expected to be completed in due course. These interests are being transferred to Calvista Colombia conditionally in connection with the grant to Calvista Colombia of two previously announced options to earn an aggregate 100% interest in the Subject Property, subject to a 1.5% net smelter return royalty, all upon the terms and conditions as detailed in the August Release. In the event that Calvista Colombia elects not to exercise the options, Calvista Colombia will transfer back its interests in the Subject Property in accordance with the terms of the underlying option agreements.

Ingeominas, Colombia's mining authority by Resolution GTRB-0208, also denied another mining exploration company several requests by which, inter alia, it opposed the foregoing assignment. Such mining exploration company has recently filed mediation request with Calvista Colombia and others before the Chamber of Commerce of Bucaramanga, by which it claims that there was an existing option agreement with the title holder of License 090-68 and that such agreement was breached; it also seeks to have the assignment to Calvista Colombia of the aforesaid interest declared null and void. The mediation request is filed in order to comply with Colombian law which provides that prior to filing civil suit the claimant must first attempt mandatory mediation with the future defendants.
