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 = Reed and others (1978) describe a float sample of quartz semischist that contains unknown secondary hydrous copper carbonate minerals.
Comment (Reference): Primary Reference = Reed and others, 1978
Comment (Commodity): Ore Material = Unidentified secondary hydrous copper carbonate minerals
Comment (Exploration): Status = Inactive.
Comment (Geology): Geologic Description = The location of this site is approximate. Reed and others (1978) describe a float sample of quartz semischist that contains unknown secondary hydrous copper carbonate minerals. The sample site lies near a thrust fault that places Devono-Mississippian(?) black shale and calcareous sedimentary rocks (Pzsl), considered to correlate with the Totalanika Schist in the Kantishna Hills to the north, over a lower Paleozoic quartzite, semischist, and metavolcanic rocks (Pzsv) (Reed and Nelson, 1980).
Comment (Deposit): Other Comments = This site is located within Denali National Park and Preserve.
