Comments on the geologic information

  • Geologic Description = This prospect reportedly is in a 3-foot-wide shear zone in slate of the Tertiary Orca Group (Jansons and others, 1984). Volcanic rocks crop out near the prospect (Nelson and others, 1985). Examination of the area by the U.S. Bureau of Mines in the early 1980s showed no obvious signs of mineralization. Three samples contained 24-140 ppm Cu (Jansons and others, 1984).
  • Age = Tertiary based on the age of the Orca Group (Nelson and others, 1985).
