Aug 22, 2013 (D Draper) - Drillhole 7609-78-7: The 15m of agglomerate returned values ranging from 0.17 to 0.47% Zn and 0.05 to 0.11% Cu. A 1-meter sample of the carbonaceous tuff at 74.2m assayed 0.53% Zn and 0.06% Cu. Drillhole 7609-78-5A was drilled approx. 500m to the southeast of 7609-78-7 and intersected 4 zones of mineralized agglomerates and tuff from 43.41 to 79.58m (EOH at 86.01m). Best assay of 0.24% Zn and 0.02% Cu was over 2.03m from 51.12 - 53.15m. Average assays over the best mineralized zone: 0.03% Cu, 0.15% Zn, 0.044 opt Ag / 11.57m. (Assays below MDI occurrence criteria).
