The Unnamed (west of Wind River) is a copper, lead, and zinc 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 (Deposit): Model Name = Polymetallic replacement deposit (?) (Cox and Singer, 1986; model 19a).
Comment (Geology): Geologic Description = Visible sphalerite and galena occur in a stratabound quartz-calcite vein (Menzie and others, 1985). The vein cuts black, recrystallized chert and chert breccia which is found at the top of the Devonian Skajit Limestone. Barker (1978) reported sulfides as disseminated crystals and veinlets in limestone and dolomite in creek rubble. Anomalous values of silver, arsenic, antimony and cadmium were noted in rock samples from this location. The bedrock is mapped as Skajit Limestone in contact with calcareous sandstone member of Hunt Fork Shale and/or Beaucoup Formation. No other descriptive information is available.
Comment (Reference): Primary Reference = Menzie and others, 1985
Comment (Workings): Workings / Exploration = The maximum values from 7 rock samples from this area are: 300 ppm Cu, 500 ppm As, 100 ppm Sb, 7 ppm Ag, [more than] 500 ppm Cd (Cathrall and others, 1977; sample number 75 RR 113 A through E, S, and T).
