Comments on the geologic information

  • Geologic Description = Harrington (1918) reported that free-milling gold in quartz veins was discovered near the head of Edgar Creek. Claims were staked on these veins, but other information about them is not available. Hoare and Coonrad (1959) show a prospect symbol at this location and interpret the country rocks as Paleozoic to Mesozoic sedimentary and volcanic strata of the Gemuk Group.
  • Age = Cretaceous or younger. Veins crosscut Carboniferous to Cretaceous rocks of the Gemuk Group (Hoare and Coonrad, 1959).
