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 = Brief reconnaissance geologic mapping and one silt sample which was barren. It does not appear occurrence has been adequately examined for epithermal gold vein potential.
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Christie, 1974
Comment (Deposit): Model Name = Porphyry copper, epithermal gold vein
Comment (Deposit): Model Number = 17, 25
Comment (Geology): Geologic Description = Color anomaly 1,500 by 5,000 ft (450 by 1,500 m) in size in volcanic and epiclastic rocks intruded by diorite and quartz porphyry(?). Anomaly is elongate, oriented N 20x E.
Comment (Geology): Age = Miocene or younger
