Comments
Comment (Geology): Age = Cretaceous or younger.
Comment (Reference): Primary Reference = Capps, 1912
Comment (Workings): Workings / Exploration = The mine has both surface and underground workings. In 1910 a 30 foot adit was driven. Capps (1911) reported that a small mill operated at the site for a month in 1909.
Comment (Deposit): Model Name = Porphyry Cu-Au(?) (Cox and Singer, 1986; model 20c)
Comment (Geology): Geologic Description = The Chute Creek mine is in Totatlanika Schist, a sequence mainly of predominantly felsic and mafic metavolcanic and metavolcaniclastic rocks that is dated as Early Mississippian to Middle Devonian (Wilson and others, 1998). At the mine the schist is cut by Cretaceous(?) rhyolite porphyry. The deposit consists of disseminated pyrite, in a zone 100 to 250 ft wide, in altered and sheared rhyolite porphyry. Capps (1912) reported grades of up to 0.435 ounce of gold per ton.
Comment (Production): Production Notes = Unknown.
Comment (Exploration): Status = Inactive
