Unnamed (east of Iron Creek)

The Unnamed (east of Iron Creek) is a copper and lead 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 (Workings): Workings / Exploration = No exploration activities are known for this locality.

Comment (Reference): Primary Reference = Asher, 1969 (DGGS R18)

Comment (Geology): Geologic Description = Asher (1869, DGGS R18) reported surface float of finely crystalline galena in quartz at this locality. Briskey (1983) identified stringers and disseminations of chalcopyrite and malachite in schist and in quartz bands in schist here. Bedrock is part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).

Comment (Deposit): Model Name = Chalcopyrite and galena in quartz-rich rocks.

Comment (Exploration): Status = Probably inactive
