Calvista Gold Corporation (TSX:CVZ)(OTCQX:CAGOF) ("Calvista" or the "Company") is pleased to announce that it has entered into an agreement to acquire part ownership of a 132 hectare exploration license bordering its Callejón Blanco prospect which shares more than 1.5km of border with AUX Canada Acquisition Inc. and on the Pie de Gallo and San Celestino mineralized gold zones. Figure 1 shows in cross-hatching the newly acquired license.

The Company's Executive Chairman, Dr. Ruben Shiffman, stated that "the California Valley in Colombia is an exciting part of the world. Calvista continues to take a parsimonious approach of drilling and integrating into the Valley. We believe this strategy will yield good returns to our shareholders."

Calvista's wholly owned subsidiary, Sociedad Minera Calvista Colombia, S.A.S. ("Calvista Colombia") has entered into an option agreement to acquire 18.787% interest of all the minerals in the entire area of license FCC-814, comprising 132 hectares and 185.5 square metres. The interest will be exercisable as follows: (i) paid upon execution of the option agreement, US$100,000, (ii) paying 20 days after execution of the option agreement, an additional US$100,000, (iii) paying upon registration at the Colombian mining authority of the transfer of the 18.787% interest to Calvista Colombia, an additional US$275,000 plus an aggregate of seven hundred thousand common shares of Calvista, (iv) paying, upon the exercise of the option agreement, an additional amount of US$600,000 plus seven hundred thousand common shares of Calvista, and granting a 2% net smelter return royalty on gold and silver on 18.787% of the production. If after the exercise of the option the aggregate amount of cash paid and common shares of Calvista issued for such exercise is less than US$2,100,000, Calvista Colombia will pay the difference in either cash or common shares of Calvista, at the option of Calvista Colombia. The issuance of common shares of Calvista in accordance with the option agreements is subject to approval by the TSX. In accordance with the option agreements, the holder of the mining license is submitting to the mining authorities all documents required to effect the transfer of the 18.787% interest to Calvista Colombia, and the term of the option agreements expires 14-months from the date of the registration of such transfers by the mining authority. The 18.787% interest is subject to transfer back by Calvista Colombia in the event Calvista Colombia does not exercise the option.
