May 26, 2016 (A Wilson) - The wall rock is somewhat schistose, mafic fragmental, volcanic rock altered to chlorite and impregnated with pyrite. In the northwest part of the property a quartz vein system (less than 6 feet wide) strikes northeast through granitic and mafic metavolcanics rocks.

May 26, 2016 (A Wilson) - Assays ranging from 0.15 to 1.20 oz./t in gold are reported from the property. The best assay from the Rochon assessment came from the shaft. Sample 10721 assayed 0.579 oz./t Au. (2) Cotterill Showing - This occurs in the northeast corner of the Wolf Lake property. Gold occurs in hydrothermal quartz veins with considerable amounts of pyrite. Several veins occur in this region, most strike east to northeast and occur in the metavolcanics. One such vein, found at the intersection of L-21 and BL10E has a width up to 5m and was traced along strike for 50m. Minor amounts of silver were found to occur here as well, up to 17.8g/t Ag. Gold values from the quartz veins were low but pyrite rich wall rocks contained values up to 1.8g/t Au.
