Aug 27, 2010 (A Wilson) - The showing occurs at the contact between the rhyolite and the dacite. The contact is sheared and hosts numerous veins, stringers and disseminations of quartz. Wide spread Zn-Pb-Ag-Cu-Au bearing sulphides are reported between the south shore of Campbell Lake on the west and Sirola Lake to the east. Assessment research indicates the possibility of multiple horizons of mineralization in the area. The mineralization is found in the central part of the Halliday Dome which consists of predominantly intermediate to felsic flows and pyroclastic rocks with lesser intermediate to mafic metavolcanic flows. The dome is intruded by smaller ultramafic bodies. The base metal sulphide mineralization is associated with cherty breccias within a large pyroclastic rock interpreted by Teck Corp. geologists as an ignimbrite. The mineralization is typically disseminated and poddy. Chlorite alteration is apparently strong and pervasive close to the best surface mineralization. Iron carbonate alteration occurs in veins and pods. A sericitic alteration is found around the chlorite alteration.

Aug 27, 2010 (A Wilson) - Grab samples collected by the OGS in 1952 from trenches on the Lamothe Property returned $6.00 per ton gold and 2% Zn. The highest assay from a grab sample collected from the trench by Canadian Arrow Mines Ltd. in 1970 returned 7.65% Zn, 0.32% Pb, 0.29 oz/t Ag and trace Au. The highest assay values were returned by the sphalerite-rich shear at the rhyolite-dacite contact zone. Three samples over a distance of 50 feet returned 7.65% Zn, 4.35% Zn and 4.30% Zn. Diamond drilling by Canadian Arrow Mines in 2001 returned 3868 ppm Zn over .5 m in sulphidized rhyolite tuff from HAL01-10.
