Report: Peacock A N50E 36SE fault zone in nearly horizontal limestone of the Helena Formation contains fine grained quartz, pyrrhotite, chalcopyrite, galena(?), and sphalerite(?). The mineralization also seems to occur in small replacement lenses along bedding. A select sample (JGDO-2) of this high sulfide material ran 0.108 oz/ton gold, 2.56 oz/ton silver, 0.26% copper, 0.073% lead, and 0.055% zinc. However, the zone is only 1-8 inches wide (Emmons and Calkins, 1913). This may be on the same structure as the Douglas Mine to the southwest. The mineralization has been explored by two adits, now caved, with a combined length of 700 feet (Emmons and Calkins, 1913).
