Jul 23, 2012 (A Wilson) - A 2.2 ft section of drill core (230.0-232.2 m) returned assays of 0.171 g/t Au, 164 ppm Cu. A 4.5 ft section of core assayed 0.24% Zn and 0.17% Cu (210.5 -215.0 m) The iron formation consists of 10-16% pyrite-pyrrhotite (intergrowths) in a quartz biotite matrix. Up to 10% magnetite is associated with the pyrite-rich zones.
