Apr 02, 2007 (Mark Puumala) - This occurrence is based on the reported presence of anomalous concentrations of copper in Card Lake Copper Mines diamond drill hole BL-3 (AFRI# 52O11SW0040). Mineralization was reported on the drill hole log to occur in a sequence logged as quartz-chlorite schist. Other lithologies noted on the drill hole log included quartz gabbro and quartz diorite. Fenwick (1970) mapped the rocks of the area as consisting largely of mafic metavolcanics (largely massive and pillowed flows), with some intercalated units of felsic to intermediate tuff and iron formation. Mineralization at this location is reported on the diamond drill hole log to consist of widely disseminated (with local sulphide concentrations of up to 25%) pyrite, pyrrhotite and chalcopyrite. Sulphides are occasionally described as occurring as massive stringers and blebs, and are also reported to occur in association with quartz veins. The most notable assays reported from this borehole were 0.17% Cu, 0.01% Ni, 0.05 oz/ton Ag and 0.005 oz/ton Au from drill sections ranging from 0.45 to 0.6 m.
