Comments on the geologic information

  • 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).
  • Age = Devonian
