The Unnamed (divide between Partin and Little Shotgun creeks) is a chromium 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 (Exploration): Status = Inactive
Comment (Deposit): Model Name = Podiform chromite (Cox and Singer, 1986; model 8a)
Comment (Geology): Geologic Description = The country rocks in the area of this occurrence are a tectonically mixed assemblages of Upper Devonian serpentinite, basalt, chert, and gabbro. The deposit consists of pods of massive chromite in serpentinite. Rock samples from the surface contained low chromium, palladium, and platinum values (Balen, 1990: OFR 34-90). The chromite probably was a mag,atic segregation on the ultramafic host rocks.
Comment (Geology): Age = the chromite probably was a magmatic segregation in Upper Devonian ultramafic intrusive rocks.
Comment (Reference): Primary Reference = Balen, 1990 (OFR 34-90)
Comment (Workings): Workings / Exploration = Surface sampling only.
