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 (Reference): Primary Reference = Alaska Earth Sciences, 2000
Comment (Workings): Workings / Exploration = This prospect is an area of trenching and surface mapping and sampling. An aeromagnetic survey was flown over the Salmon River 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 (Exploration): Status = Active
Comment (Deposit): Model Name = Alaskan PGE (Cox and Singer, 1986; model 9)
Comment (Geology): Geologic Description = The east border zone of the Jurassic Red Mountain ultramafic pluton was prospected by a series of 12 trenches located from near Fox Gulch north to beyond Clara Creek. The trenching was accompanied by surface mapping and sampling (Alaska Earth Sciences, 2000). The Red Mountain ultramafic 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. A 1-meter-wide zone assaying 2.26 grams of PGM per ton was identified in the trench near Fox Gulch (T. Hinderman, oral commun., 2000), but in general the exploration results were apparently not encouraging.
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.
