Calvista Discovers New Mineralized Zones

TORONTO, ONTARIO--(Marketwire - Sept. 11, 2012) -

Editors Note: There is a map associated with this press release.

Calvista Gold Corporation (TSX:CVZ)(OTCQX:CAGOF) ("Calvista" or the "Company") is pleased to announce that its recent soil sampling program has identified two new mineralized zones at the Company's Callejón Blanco prospect within its wholly-owned California Valley Project ("the Project").

The Company's Chief Executive Officer, Mr. Mark Haywood, stated that "the exciting discovery of two new mineralized zones parallel to our previously discovered zones on the La Mascota ore zone represent major exploration targets for Calvista. Further exploration under our upcoming Phase III diamond drilling program will have the potential to significantly increase our mineral resources at the Callejón Blanco prospect."

Under the Company's soil sampling campaign, all Calvista's licenses were sampled on a 100 x 50 metre GPS grid using the company's codified card system.

A total of 351 samples were taken from the upper part of the B Horizon and assayed using Enzyme leach technology by Activation laboratories in Canada.

Figure 1 highlights the two new interpreted mineralized zones at the Callejón Blanco prospect.

Table 1 in Appendix A also shows selected results from the Company's soil sampling campaign.

Additional magnetic susceptibility and temperature surveys were completed and integrated into the interpretation of the targets. Geochemical results were processed using Compositional Data Analysis and other statistical methods such as Factor Analysis and Correlation Studies.

As the result of these studies, new target zones were identified and drilling targets were selected for Calvista's Phase III drilling campaign.
