Comments
Comment (Exploration): Status = Inactive
Comment (Workings): Workings / Exploration = Sampling of the vein during brief U.S. Geological Survey field work in 1993 yielded 100 ppb Au, 0.12 ppm Hg, 14 ppm Ag, 4,700 ppm Cu, 3,700 ppm Zn and 110 ppm Pb (sample 93 AWs 16). A mineralized sample of the volcanic breccia yielded 50 ppb Au, 11 ppm Ag, 4,700 ppm Cu, and 4,000 ppm Zn (sample 93 AWs 16b).
Comment (Deposit): Model Name = Polymetallic vein
Comment (Geology): Geologic Description = Volcanic breccias of the Finger Bay Volcanics are cut by a shear or fault zone, exposed in quarry. Zone is filled by quartz vein carrying abundant sulfide minerals, including chalcopyrite. Malachite/azurite staining coasts surrounding rocks. Epidote veins and segregations are common in vicinity of vein -- one float boulder of epidote was 30 cm in diameter.
Comment (Geology): Age = Tertiary
