South Currant Creek

The South Currant Creek is a zinc and copper 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 (Exploration): Status = Inactive

Comment (Geology): Geologic Description = Limestone and diorite float boulders contain disseminated pyrite, magnetite, and chalcopyrite. Limestone has been slightly altered to skarn, calc-silicate veins cut diorite and granodiorite. Stream sediment samples yielded up to 220 ppm Cu, 500 ppm Zn, 0.4 ppm Au (Resource Associates of Alaska, 1976). The locality is in the vicinity of a contact between Tertiary medium-grained biotite-hornblende granodiorite unit (with some granite and quartz monzodiorite) and a Cretaceous granodiorite unit which ranges in composition from mafic tonalite to quartz diorite (Nelson and others, 1983; units Ti11 and Ki9).

Comment (Workings): Workings / Exploration = Stream sediment samples yielded up to 220 ppm Cu, 500 ppm Zn, 0.4 ppm Au (Resource Associates of Alaska, 1976).

Comment (Deposit): Other Comments = Site is in Lake Clark National Park and Preserve.

Comment (Deposit): Model Name = Cu skarn (Cox and Singer, 1986; model 18b)

Comment (Production): Production Notes = No production

Comment (Reference): Primary Reference = Resource Associates of Alaska, Inc., 1976

Comment (Reserve-Resource): Reserves = No reserves

Comment (Geology): Age = Intrusives associated with the skarn are Cretaceous to Tertiary.
