Dec 07, 2005 (K R Kettles) - Gold associated with pyrrhotite, pentlandite and chalcopyrite has been reported at this locality(Riley, 1975) , from a trench in argillite that strikes roughly northwest and dips 80 degs NE. Diamond drilling indicates that the showing is underlain by interlayered gabbro sills, mafic flows and tuff, cherty magnetite iron formation, pyritic quartzite and argillite, and graphitic sediments. Some quartz veining exists, and some of the argillaceous rocks are silicified and carbonatized. Andalusite was noted at several places.

Sep 30, 2020 (K R Kettles) - A trench with gold associated with pyrrhotite, pentlandite and chalcopyrite in pyritic to sulphide-rich argillite is reported to contain gold (Riley, 1975). Some quartz veining exists, and some of the argillaceous rocks are altered. Auriferous sulphide-rich sediments may be continuous over a strike of about 750 m. The trench is which gold was noted is about 61 m north of a HLEM anomaly 750 m long. A grab sample in 1969 assayed: 0.01 opt Au, trace Ag, 0.05% Cu, 0.20% Ni. Grade 1979 DDH M-79-6: 0.35% Ni, 0.13% Cu/5 ft (133-138), 0.04 opt Au/5 ft (153-158) on reassay.
Dec 07, 2005 (K R Kettles) - The sulphide-rich argillaceous rocks are silicified and carbonatized, and contain Andalusite.
