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 = Active

Comment (Deposit): Model Name = Kipushi

Comment (Geology): Geologic Description = Three types of mineralization reported (Cobb and Mayfield, 1981, p. A4): 1. dolomitic zones containing disseminated blebs of chalcopyrite and bornite; malachite on weathered surfaces; 2. layered pyrite and chalcopyrite in schist; 3. malachite and azurite in quartz veins. Considered a hydrothermal replacement-type deposit in dolomite and dolomite breccia (Nana Development Corp., written comm., 1997).

Comment (Reference): Primary Reference = Cobb and Mayfield, 1981

Comment (Workings): Workings / Exploration = Prospect located on Nana Corporation lands currently (1997) under exploration that includes geologic mapping, geochemical sampling, and diamond drilling. Additional exploration work completed by Kennecott Exploration in 1994 and 1995.

Comment (Geology): Age = Devonian
