Sep 18, 2017 (Therese Pettigrew) - The surface geology consists of part of a mafic-ultramafic sill which is overlain by a well-bedded dacitic tuff. The sequence has been intruded to the north and east by the Stephen Lake Pluton. Zinc and copper mineralization has been found to occur in the dacitic tuff (Davies and Morin, 1976).

Sep 18, 2017 (C Ravnaas) - Grade: best assay - 10.8% Zn and 0.21% Cu over 3 ft in DDH. Best intersection from the 1983 drill program returned 2.0% Zn and 0.8% Cu over 3.4 m. Assays from the 1984 channel samples included 3.26% Zn and 0.51% Cu over 1.7 m. Best intersection from the 1984 drill program assayed 1.33% Zn, 0.1% Cu over 4.6 m.
Sep 18, 2017 (Therese Pettigrew) - Zinc and copper mineralization has been found to occur in the dacitic tuff. It appears that the mineralization occurs in a zone varying from 3 m to 6 m in thickness that is conformable to the bedding of the enclosing pyroclastics and that has been traced for at least 180 m. Within this zone, the mineralization varies from sulphides disseminated within and along the bedding to lenses of massive sulphides. The sulphide minerals present are pyrite, pyrrhotite, chalcopyrite, and sphalerite. The nature of the mineralization is very similar to that exposed in an outcrop of dacitic tuff along the shoreline of a partly drained lake about 2400 m NW of this showing (Davies and Morin, 1976).
