The Unnamed (northern Russian Mountains) is a antimony, lead, copper, 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.

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 = Surface observation and sampling has been completed (Bundtzen and Laird, 1991).
Comment (Deposit): Model Name = Polymetallic veins (Cox and Singer, 1986; model 22c)
Comment (Reference): Primary Reference = Bundtzen and Laird, 1991
Comment (Geology): Geologic Description = Bundtzen and Laird (1991) report two, small, malachite-stained quartz veins containing chalcopyrite, galena, and arsenopyrite. The veins are 1 to 3 centimeters wide and occur along northwest-trending joints in the cupola zone of a syeno-monzonite just below the contact with thermally metamorphosed andesite country rocks. A sample of the veins contained 0.46 percent arsenic, 0.13 percent antimony, 0.94 percent lead, 0.09 percent cadmium, and 45 ppm silver; gold was not detected. The veins are in the Upper Cretaceous intrusive complex of the Russian Mountains (Bundtzen and Laird, 1991).
Comment (Geology): Age = Late Cretaceous or Tertiary. Veins crosscut part of the intrusive complex of the Russian Mountains. Quartz monzonite from this complex has yielded a K/Ar age of 70.3 +/- 2.1 Ma (Bundtzen and Laird, 1991).
Comment (Exploration): Status = Inactive
