Economic information

Comments on the geologic information

  • Geologic Description = Limonite-stained quartz-cemented fractures in Tertiary biotite +/- hornblende granite. USGS grab samples contained 0.15 percent Pb, 10 ppm Ag, and 0.2 percent As (Jansons and others, 1984).
  • Age = Tertiary or younger; mineralized fractures cut Tertiary granite.
