Apr 21, 2016 (D Guidon) - Assays above 500 ppb Au are associated with a felsic intrusive intersected between 146.2 and 152.4 m down hole and at the intersection of altered volcanic rocks immediately down hole from the felsic intrusive. The felsic intrusive is described as a buff coloured sericite schist, possibly a highly altered quartz porphyry containing 1% fine pyrite and up to 1% locally acicular arsenopyrite.
