The Unnamed is a gold, copper, and tungsten 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 = Reed and others, 1978
Comment (Commodity): Ore Material = Unidentified sulfides
Comment (Commodity): Ore Material = oxides
Comment (Geology): Age = Late Cretaceous/early Tertiary; mineralization is interpreted to be related to the East Fork Yentna stock, one of the composite plutons mapped by Reed and Nelson (1980).
Comment (Workings): Workings / Exploration = Reconnaissance mapping, stream silt, pan concentrate and rock sampling by the U.S. Geological Survey (Reed and others, 1978; Reed and Nelson, 1980) are all that have been described here. Maximum values of 2 ppb gold, 1 ppb palladium, and 5 ppb platinum from the East Fork stock are reported by Foley and others (1997).
Comment (Geology): Geologic Description = Reed and others (1978) describe disseminated sulfide minerals (unidentified) in felsite dikes of the East Fork Yentna stock, a medium-grained, pyroxene-bearing biotite granite, that is one of the composite plutons (Tcp) of Reed and Nelson (1980). Maximum values of 2 ppb gold, 1 ppb palladium, and 5 ppb platinum from the East Fork stock are reported by Foley and others (1997).
Comment (Exploration): Status = Inactive
