The Red Mountain is a platinum 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 (Geology): Age = Jurassic, the age of the Red Mountain ultramafic pluton. Hoare and Coonrad (1978) report K/Ar ages for two samples of amphibole from the southeast border of the Red Mountain pluton: 176.4 +/- 5.3 Ma and 186.9 +/- 5.6 Ma.
Comment (Reference): Primary Reference = Alaska Earth Sciences, 2000
Comment (Workings): Workings / Exploration = An aeromagnetic survey was flown over the Salmon River (Goodnews) area in 1994, a gravity survey has been completed, and some controlled-source audio magneto-telluric lines have been run over selected parts of the ultramafic complex (Alaska Earth Sciences, 2000).
Comment (Geology): Geologic Description = This prospect represents the deeper, subsurface part of the Red Mountain ultramafic pluton. This large Jurassic pluton is mostly dunite, but the eastern border zone includes bands of peridotite, clinopyroxenite, and hornblende-bearing rocks that are zoned outward from dunite in that order. Gravity and aeromagnetic surveys over the Red Mountain pluton show that it is thicker and more deeply seated in its southern part (Alaska Earth Sciences, 2000). This relationship has led to the interpretation that the ultramafic magma was emplaced through a deep feeder conduit in this area. A conceptual diagram of this prospect infers a sulfide-rich, PGM-bearing cumulate zone along the footwall of the feeder conduit (Alaska Earth Sciences, 2000).
Comment (Deposit): Model Name = Alaskan PGE (Cox and Singer, 1986; model 9)
Comment (Exploration): Status = Active
