Sep 14, 2020 (Therese Pettigrew) - This occurrence is located about 32 km west of Atikokan, on the north shore of Gehl Lake. The occurrence consists of a brecciated quartz vein, 75 m long and 1 m wide, within a 2 m wide shear zone in a metasedimentary host rock. It varies in strike from 268 degrees to 300 degrees and dips 70 degrees to vertical. The vein material varies from milky white to sugary white to smoky quartz and contains disseminated pyrite and chalcopyrite. Carbonate locally cuts the vein. Two 2 m by 2 m pits were noted. Ten grab samples of all rock types present were assayed for Au, Ag and Cu. The highest assay results were 0.01 ounces per ton Au, 0.24 ounces per ton Ag and 0.59 percent Cu (Fenwick et al., 1980).
