Comments on the geologic information

  • Geologic Description = The occurrence noted by Albanese (1984) is a sample of limonite-stained quartzite. A rock sample contained 294 ppm Cu, 7 ppm Pb, 42 ppm Zn, 15.0 ppm Au, 4.2 ppm Ag, 20 ppm Mo, 4 ppm Sn, 525 ppm W, and 609 ppm Mn. Weber and others (1978) describe the regional geology as gneiss and quartzite.
