Jul 20, 2012 (A Wilson) - A 4.5 ft section of drill core (99.8-104.3 m) returned assays of 0.069 g/t Au, 75 ppm Zn, 68 ppm Cu over 5 feet, 0.034 g/t Au, 256 ppm Zn and 330 ppm Cu over 2 m and 0.034 g/t Au, 280 ppm Cu and 79 ppm Zn. A 16.1 m interval of the drill hole (255.5-271.6 m) returned a best assay of 0.069 g/t Au, 151 ppm Zn and 64 ppm Cu over 3 feet. The main sulphide zone is described as consisting of spongy pyrite-rich zones, pyrrhotite intergrowths with disseminated magnetite grains.
