Aug 04, 2022 (Q Unknown) - The showing lies within a basic intrusive immediately adjacent to a pronounced drift-filled topographic depression, which may be a fault zone. Disseminated chalcopyrite and nickeliferous pyrrhotite in gabbro body at border of granodiorite stock in volcanics. Chalcopyrite also occurs in a rhyolite dike. Best grab samples in gabbro assayed 0.63% Cu and 0.37% Ni. Best grab samples from rhyolite dike assayed 4.14% Cu. (MDC012, 1969, p. 158, 159)(Kenora RGP, SMDR#00545, Historical Files - 52F08NW00042).
