Sep 27, 2018 (Therese Pettigrew) - Magnetite is found in iron-formation zones, which are intercalated with basic tuffs. Known iron-formation zones are restricted to the southern part of the south belt of mafic metavolcanic rocks, and are exposed north and west of Grouse Lake and the larger of the two unnamed lakes immediately southwest of Grouse Lake. Exposed individual iron-formation zones are small; they do not appear to exceed 300 feet in length, and do not exceed 60 feet in thickness. The iron-formation zones constitute a minor part of the tuff-iron-formation assemblage (Giblin, 1964).
