The Unnamed is a 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 (Workings): Workings / Exploration = Grab sample assayed (MacKevett, 1976): 0.06 ppm Au (AA), 1,500 ppm Cu, 7 ppmMo, > 20 percent Fe. Type of workings: surface
Comment (Deposit): Other Comments = Not large enough to encourage development on the basis of iron content alone.
Comment (Geology): Geologic Description = Magnetite-rich skarn containing disseminated chalcopyrite developed in Triassic marble near Jurassic granodiorite pluton.
Comment (Reference): Primary Reference = MacKevett and others, 1978
Comment (Deposit): Model Name = Cu skarn
Comment (Exploration): Status = Inactive
