Comments on the geologic information

  • Geologic Description = This site appears to be underlain by a Tertiary pluton (Detterman and others, 1981). MacKevett and Holloway (1977) suggest that this occurrence is a porphyry-type deposit associated with an altered Tertiary intrusion. The U.S. Bureau of Mines (1973) lists the commodities at this site as gold, lead, and silver and indicates that claims were active here during the mid-1960's.
  • Age = Tertiary.
