The Cold Spring is a bismuth 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 = Miller and Grybeck, 1973
Comment (Geology): Age = Quaternary
Comment (Geology): Geologic Description = A cold spring comes to the surface at this locality and a grab sample of surface material here contained greater than 10,000 ppm bismuth (Miller and Grybeck, 1973). This location is close to an inferred range front normal fault with probable Quaternary displacement. However, an alluvial fan is developed where the nearby stream enters onto the lowland of Death Valley and the surface trace for the inferred fault is not apparent.
Comment (Deposit): Model Name = Surface precipitates from a cold spring contain Bi
Comment (Workings): Workings / Exploration = None.
Comment (Exploration): Status = Inactive
