Target Area: San Pedro de Hercules

Location, Geology and Mineralization

Located in the southern part of the district, the San Pedro de Hercules target consists of a series of west-trending quartz veins and stockwork zones cutting Tertiary volcanic rocks. Surface sampling has returned encouraging values in silver, lead and zinc, with several samples containing more than 200 grams per tonne silver. The area is located to the north of the Cozamin mine of Capstone Mining and exhibits several of the characteristics of the upper portions of the Mala Noche vein system, host to Capstone's orebody.

Drill Results

During 2010, we completed a drill program consisting of nine holes totaling 3,173 meters at the San Pedro de Hercules target. We intercepted interesting mineralization in several holes, including 1.15 meters averaging 2.5 grams per tonne gold, 240 grams per tonne silver, 0.59% lead and 2.53% zinc in hole SJ-10-02 and 2.05 meters averaging 602 grams per tonne silver, 0.62% lead and 1.87% zinc in hole SJ-10-03. We think this can be compared favorably with the upper zone at the nearby Cozamin mine and the potential for higher copper grade at depth may be good. We plan to drill several holes in 2011 to test the deeper parts of the vein system at a cost of about $350,000.
