Exploring the Sierra Madre of Mexico for gold and base metals.
Historic workings at El Pino expose a quartz-sulfide vein hosted mainly in glassy pyroclastic rocks that probably correlate with the Socavón Volcanics. Mineralization consists mainly of galena, sphalerite and copper sulfides such as chalcocite, bornite and chalcopyrite. Iron sulfides are mainly pyrrhotite and pyrite. On surface, mineralization is oxidized to copper and lead sulfates such as linarite, brochantite and anglesite. Gold is apparent in crushed and panned samples. El Pino vein has been traced out on surface between MCA-25216 and MCA-25242 for 650 m over an elevation range of 300 m between 852 meters and 552 meters elevation.
