Comments on the geologic information

  • Geologic Description = Capps (1919) describes the Flaurier prospect as sulfide-bearing porphyry dikes that cut Triassic chert, argillite, tuff, and limestone. The dikes are similar in composition to those at the Golden Zone mine (HE043). The sulfide minerals are arsenopyrite and chalcopyrite, and they apparently are widely disseminated in the prospect area. Samples reportedly contain significant gold and silver values.
  • Age = Probably Late Cretaceous (70 -65 Ma).
