Feb 11, 2010 (Mark Puumala) - This discretionary occurrence is based on the reported presence of slightly anomalous concentrations of base metals in Cominco diamond drill hole MC 79-3 (AFRI# 53C04NE0002). The mineralized zone that was sampled and assayed by Cominco was reported to consist of intermediate metavolcanics mineralized with approximately 7% pyrrhotite and 3% pyrite. The pyrrhotite occurs as disseminations and small (<1 mm) interconnected blebs, while pyrite occurs as larger (up to 3 mm) irregular blebs that cross-cut the pyrrhotite and are aligned parallel to foliation. The most significant assay reported on the drill hole log was 310 ppm Cu over 1.5 m.
