The Unnamed is a copper 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 (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Smith and Eakin, 1911
Comment (Deposit): Model Name = Polymetallic veins and disseminations in high grade metamorphic rocks
Comment (Geology): Geologic Description = Simth and Eakin (1911) report disseminated lenses and stringers of chalcopyrite and its oxidation products, near a contact between schist and limestone (marble). A little gold is also reported. This base metal occurrence, and several others in this part of the Bendeleben A-4 quadrangle, are in high grade metasedimentary rocks that are structurally above or peripheral to the croscutting Pargon pluton. The Pargon pluton is mostly granodiorite and assumed to be Cretaceous in age (Till and others, 1986). It was emplaced at shallower depths than the more deep-seated Bendeleben pluton to the east.
Comment (Workings): Workings / Exploration = Some small hand dug prospecting pits may be present.
Comment (Geology): Age = Cretaceous; this occurrence is probably related to emplacement of the Pargon pluton which is assumed to be Cretaceous in age.
