The Unnamed (north of Reds Lake) 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 (Reference): Primary Reference = Grybeck, 1977
Comment (Geology): Geologic Description = Schmidt (1997, loc. 50) includes this occurrence with three, presumably similar, occurrences. They are described as quartz veinlets containing malachite-azurite plus or minus pyrite, chalcopyrite, and pyrrhotite in the Silurian and Devonian Skajit(?) Limestone and overlying siltstone and limestone (Beaucoup Formation?). The geologic map indicates that this occurrence is near a thrust contact between Devonian(?) purple, green, and red chloritic slate and phyllite and the Devonian(?) Skajit Limestone (Brosgi and Reiser, 1964). No other information is available.
Comment (Deposit): Model Name = Polymetallic veins(?) (Cox and Singer, 1986; model 22c)
Comment (Exploration): Status = Inactive
