May 27, 2015 (A Wilson) - The shaft was sunk on an outcrop described variously as sulphide-rich clastic sediments and sheared intermediate metavolcanic rocks. The metavolcanic rocks have been sheared and are now composed of sericite and chlorite. The quartz veins are up to 4 feet wide and consist of blue quartz with blebs of pyrrhotite, pyrite, chalcopyrite, red sphalerite and arsenopyrite. Diamond drilling intersected four zones of mineralization consisting of finely disseminated pyrite, pyrrhotite, chalcopyrite, and arsenopyrite in banded cherts and carbonate.
