Acquisition of Prospective Mariana Concessions

VANCOUVER - San Marco Resources Inc. has signed an agreement with Argonaut Gold Inc. to acquire 100% ownership of the Mariana property, a 73,902 hectare land package in the vicinity of the Company's Cuatro de Mayo project in eastern Sonora State, Mexico. As a result, San Marco now owns or has optioned full ownership of approximately 93,000 hectares of highly prospective ground in the Sierra Madre Occidental Gold Belt and is one of the largest exploration landholders in the area.

The Mariana property (now part of the Company's Cuatro de Mayo Regional Project) extends roughly 60 km in a northwest direction, has a width of approximately 20 km, and surrounds the Company's existing CdM East concession. Its southeastern boundary is within 20 km of the La India and Mulatos gold mines to the south and the Dolores silver/gold mine to the east.

Robert Willis, President and CEO said, "Our acquisition of the extensive and well-positioned Mariana concessions is another step in the fulfillment of our objective to build a significant land position in a proven mineral belt through the low-cost acquisition of exploration concessions with known mineral targets and considerable upside potential. Our exploration team will commence field work in early March in order to evaluate and prioritize existing and potential new targets. Concurrently, we continue to evaluate additional acquisitions in the vicinity of our Cuatro de Mayo properties."
