| Location and accuracy | Located 4.5 mi. (7.2 km) west of Bornite on ridge in sec. 10, T. 19 N., R. 8 E., Kateel River Meridian. Shown as locality 21 in Mayfield and Grybeck (1978). Location accurate to within 1000 ft. (300 m). |
Geologic descriptionThree 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 communication, 1997). | |
