The Unnamed (southern Russian Mountains) is a antimony 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 = Bundtzen and Laird, 1991
Comment (Geology): Geologic Description = This occurrence consists of two gossan-rich quartz veins, as much as 1.5 feet wide, along northwest-trending joints and fractures in quartz syenite (Bundtzen and Laird, 1991). Sulfide minerals were not identified in these strongly oxidized veins. Samples contained up to 0.3 percent arsenic, 1.5 percent antimony, 353 ppm neodymium, 54 ppm tantalum, and 52 ppm uranium. The host quartz syenite is part of the Late Cretaceous intrusive complex of the Russian Mountains (Bundtzen and Laird, 1991).
Comment (Workings): Workings / Exploration = Surface observation and sampling has been completed.
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 (Deposit): Model Name = Polymetallic veins? (Cox and Singer, 1986; model 22c)
Comment (Exploration): Status = Probably inactive
