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 Maddren, 1909

Comment (Workings): Workings / Exploration = Adit on two shear zones and surficial workings along brecciated flow top containing native Cu. Type of workings: surface and underground

Comment (Geology): Geologic Description = Two shear zones, each less than 1 m thick, in Triassic Nikolai Greenstone contain chalcocite, bornite, covellite, malachite, azurite. Nearby brecciated flow top in Nikolai Greenstone contains native Cu.

Comment (Deposit): Model Name = Lode: vein, shear zone, disseminated

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

Comment (Exploration): Status = Inactive
