Unnamed

The Unnamed is a gold, molybdenum, 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 (Reference): Primary Reference = Christie, 1974

Comment (Workings): Workings / Exploration = Brief reconnaissance mapping and 1 soil sample reported in Christie (1974). Soil sample (W-6) showed 13 ppm Mo, 3.4 ppm Ag, and 0.02 ppm Au.

Comment (Deposit): Model Name = Copper porphyry, epithermal gold vein(?)

Comment (Deposit): Model Number = 17, 25

Comment (Geology): Geologic Description = Tabular color anomaly centered on andesite (or altered diorite?) dikes cutting the Unalaska Formation (see Drewes and others, 1961). Occurrence contains 3 percent disseminated sulfides, largely pyrite(?) over an area 300 feet (90 m) by 2 miles (3.2 km). No chalcopyrite was seen.

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Miocene or younger
