Deposit Model: Kipushi
Location: Located 4.5 mi. (7.2 km) west of Bornite on ridge in sec. 10, T19N, R8E, Kateel River Meridian. Shown as locality 21 in Mayfield and Grybeck (1978). Location accurate to within 1000 ft. (300 m).
Geology: 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).
Workings: 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.
Age: Devonian.
