Comments on the geologic information

  • Geologic Description = The mineral occurrence is within a large felsic granitic intrusion of Tertiary age (Brew and others, 1978). A representative sample from a 3-foot wide shear zone in the granite contained 7 ppm silver, 1500 ppm zinc, and 300 ppm lead (MacKevett and others, 1971, table 9).
  • Age = Tertiary.
