Comments on the geologic information

  • Geologic Description = The country rock in the vicinity of the occurrence is graywacke and shale of the Tertiary Orca Group (Nelson and others, 1985). The bedding strikes N75E and dips west. The mineralization consist of stringers of and disseminated chalcopyrite and bornite within fracture zones that parallel bedding (Schrader and Spencer, 1901).
  • Age = Teriary or younger; mineralized fractures cut Tertiary Orca Group rocks.
