Mar 29, 2007 (Mark Puumala) - Janes, Seim and Storey (1991) indicate that this occurrence is located within a 3 to 5 m wide mineralized shear zone in mafic metavolcanics. The shear zone occurs at the contact between mafic metavolcanics and greywacke (Bonner 1992). The mineralized shear zone is reported by Janes, Seim and Storey (1991) to have an orientation of 090/86. The metasediment/metavolcanic contact zone is reported by Bonner (1992) to be silicified, while the central portion is fissile chloritic schist that contains narrow lenses of grey to white quartz (Janes, Seim and Storey 1991). Mineralization is reported by Janes, Seim and Storey (1991) to consist of pyrite stringers parallel to foliation planes, with an average concentration of approximately 3%. Sampling of this occurrence by Belore Mines is reported to have returned assays of up to 0.45% Cu, while a 1990 OGS sample is reported to have returned an assay of 14,126 ppb Au (Janes, Seim and Storey 1991). Subsequent surface sampling and diamond drilling by BHP Minerals did not produce any significant assay results (Waldie 1993).
