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 = Moffit and Mertie, 1923

Comment (Workings): Workings / Exploration = Type of workings: surface. Open-cuts.

Comment (Deposit): Model Name = Basaltic Cu

Comment (Geology): Geologic Description = Native Cu, associated with epidote and chalcocite, in compact quartz stringers and lenses filling amygdules in Triassic Nikolai Greenstone. Sparsely disseminated native Cu and minor chalcopyrite also occur in the greenstone. Mineralization restricted to upper amygdaloidal parts of flows that range from 5 to 25 feet thick.

Comment (Commodity): Ore Material = Copper (native)

Comment (Exploration): Status = Inactive
