Aug 27, 2010 (A Wilson) - 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) - Chip samples collected by Teck in 1974 yielded assays of 0.74% Zn over 22 ft. and 0.4% Zn over 6 ft. Assays from DDH LR 77-2 returned: 3.19% Zn, 154 ppm Pb, 0.047 oz/t Au, 0.23 oz/t Ag over 7.5 ft. Assays from DDH LR-77-4 returned 2.45% Cu, 0.10% Zn, 0.003 oz/t Au, 0.04 oz/t Ag over 1 ft. and 0.35% Cu, 0.93% Zn, 0.075 oz/t Au and 0.27 oz/t Ag over 2.8 ft.
