Feb 28, 2018 (Therese Pettigrew) - There are 2 pits, spaced 24.3 m apart, along the south shore of the peninsula. Tanton (1935) reports that Cu-Ni sulphides are also exposed in a small pit 213.4 m along strike to the southwest. The width of mineralized rock exposed is 0.6 m. Mineralization consists of pyrrhotite, chalcopyrite, pentlandite, and pyrite, which occurs as irregular veinlets up to 10 cm wide in a tabular-shaped body of norite. The norite itself is up to 1 m wide and occurs in, and parallels in strike, the diabase dyke. The diabse is lustre mottled (ophitic) and coarser-grained than the norite and is readily distinguished. The mineralized zone can be traced on the surface for 35 m. A 1 m chip sample across the zone, 10.7 m from its east end, in a pit having a diameter of 2.4 m and a depth of 1.2 m, was found by the OGS lab to contain 0.45% Cu, 0.32% Ni, and 0.01 opt Pt and 0.01 opt Pd. A sample taken in 1925 by E.A. Bell and reported to contain 3% Cu and 1.5 % Ni may have been a grab of some of the better mineralized material (Pye, 1965).
