Comments on the geologic information

  • Geologic Description = As reported by Albanese (1984), the occurrence is a pod of gossan containing arsenopyrite, chalcopyrite, and chalcopyrite in calc-silicate rock. Weber and others (1978) describe the country rock as quartzite, slate, calc-phyllite and marble. The occurrence is located near contact of a Tertiary to Cretaceous granodiorite to quartz monzonite intrusion. An assay of a rock sample contained 475 ppm Cu, 3 ppm Pb, 3 ppm Zn, 1.5 ppm Ag, 2 ppm Mo, 5 ppm Sn, greater than 1000 ppm W, 465 ppm As, and 1,330 ppm Mn (Albanese, 1984).
