The Unnamed is a silver and gold 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 (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Christie, 1974
Comment (Workings): Workings / Exploration = Brief reconnaissance geologic mapping and a few soil and silt samples. Gold, silver, and zinc were slightly anomalous, at 0.02, 1.4, and 104 ppm , respectively. Copper and molybdenum were at background levels.
Comment (Deposit): Model Name = Epithermal gold vein
Comment (Geology): Geologic Description = Christie (1974) described a color anomaly associated with a weak gossan developed at the contact of a quartz diorite pluton with volcanic rocks of the Belkofski Formation. Volcanic rocks include andesitic crystal tuffs and flows. The area of gossan is a maximum of 5,000 by 3,000 ft (1,500 by 900 m) and shows disseminated pyrite mineralization, generally in trace amounts, but locally as high as 2 percent. Approximately half of the pyrite is fracture controlled in local zones of higher pyrite content.
Comment (Deposit): Other Comments = In Christie's (1974) evaluation, this occurrence had no sufficiently large covered area to hide a porphyry system and no copper mineralization was suggested.
Comment (Geology): Age = Pliocene or younger
