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 (Commodity): Gangue = nemalite
Comment (Workings): Workings / Exploration = 4 or 5 surface trenches dug by USBM circa WW II. Small test shipment made during World War ll but no production (Anderson, 1945, p. 19-20).
Comment (Reference): Primary Reference = Heide and others, 1949
Comment (Deposit): Model Name = Serpentine-hosted asbestos
Comment (Geology): Geologic Description = Network of low grade cross-and slip-fiber chrysotile veinlets 0.5-2.0 in. (1-4 cm) wide in area of serpentine float 800 ft. (244 m) long, several hundred feet (60 m) wide and up to 8 ft. (2.5 m) deep. Nearby magnesite veinlets and asbestos as well as residual boulders of nephrite occurr over a wide area of serpentinized ultramafic rocks cutting schist (Heide and others, 1949, p.16-18).
Comment (Exploration): Status = Inactive
