Chute Creek

The Chute Creek is a gold and silver mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

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
