Nov 05, 2007 (Mark Puumala) - This discretionary occurrence is based on the reported presence of slightly anomalous concentrations of base metals in Cominco diamond drill hole MC 79-1 (AFRI# 53C04NW0001). The mineralized zone that was sampled and assayed by Cominco was reported to consist of intermediate tuff mineralized with approximately 5% pyrrhotite occurring as irregular veinlets or thin layers (<5 mm) parallel to bedding. The most significant assays reported on the drill hole log were 190 ppm Cu, 110 ppm Pb, 320 ppm Zn and 200 ppm Ni over 1.0 m.
