The Toni showing is located on the Nanaimo River, about 4 kilometres south of Labour Day Lake.
Volcaniclastics, volcanics and sediments of the Sicker and Buttle Lake groups are intruded by quartz monzonite to granodiorite of the Early to Middle Jurassic Island Intrusions. These are overlain by sediments of the Cretaceous Comox Formation of the Nanaimo Group. The Sicker Group includes andesite and volcani- clastics of the Upper Devonian McLaughlin Ridge Formation. The Buttle Lake Group includes limestone and chert of the Mississippian to Pennsylvanian Fourth Lake Formation. These two formations were previously known as the Myra Formation.
Pyrite and minor pyrrhotite and chalcopyrite occur in quartz- carbonate veins in shear zones within the volcanics. A sample assayed 0.175 per cent copper (Assessment Report 14729).
