Unnamed

The Unnamed is a copper, molybdenum, and gold 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): Geologic Description = Disseminated pyrite and chalcopyrite in small stock of diorite porphyry of Cretaceous-Tertiary age that intrudes Jurassic-Cretaceous marine sedimentary rocks.

Comment (Workings): Workings / Exploration = Average grade from surface sampling: <0.10% Cu and <0.01% Mo, gold reported present, but no assay data given (USGS MF-655K, loc. 54). Type of workings: surface.

Comment (Deposit): Model Name = Lode: porphyry

Comment (Deposit): Other Comments = the small stock at this location may be a marginal facies of the Klein Creek batholith
