Comments on the geologic information

  • Geologic Description = The drainage area of the creek containing the Caribou gold placer prospect is underlain by Cretaceous or Jurassic turbidites and Lower Tertiary volcanic rocks (Wilson and others, 1998). A single sample of the placer contained 300 ppb gold and 8 ppm tin (Balen, 1990: OFR 34-90). The source of the placer gold and the tin is unknown.
  • Age = Quaternary.
