The Unnamed is a gold and silver 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 collection of a few silt samples reported by Christie (1974). Silver to 1.4 ppm and zinc to 99 ppm; otherwise background levels for copper, molybdenum, and gold.
Comment (Reference): Primary Reference = Christie, 1974
Comment (Deposit): Model Name = Epithermal gold vein, polymetallic vein
Comment (Deposit): Model Number = 22c, 25
Comment (Geology): Geologic Description = Christie (1974) reports a 3,000 by 3,000+ ft (900 by 900+ m), elongate to the northeast, color anomaly in volcanic rocks, mainly breccia and flows(?). His interpretation was that alteration was solfataric. No signs of fracture-controlled mineralization, epidote, or intrusive rocks.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Pliocene or younger
