Comments on the geologic information

  • Geologic Description = This occurrence consists of a 3-inch vein of fine-grained, massive sulfides in andesite that intrudes sedimentary units of the Paleocene to Eocene Tolstoi Formation (Wilson and others, 1995). The locality is approximately 2,500 feet southeast of the contact of the American Bay batholith. One rock sample collected by the U.S. Geological Survey in the mid-1980's was reported to be anomalous in antimony, arsenic, copper, lead, silver, tin, and zinc (Wilson and others, 1988).
  • Age = Tertiary.
