Comments on the geologic information

  • Geologic Description = No specific data reported about the prospect mentioned in Capps (1919). Most likely, gold-bearing quartz vein(s) cut the Late Cretaceous Willow Creek Pluton. Bedrock is the Late Cretaceous Willow Creek Pluton. The Willow Creek Pluton is a zoned pluton: the outer part consists of hornblende quartz diorite and lesser hornblende tonalite; the core consists of hornblende-biotite granodiorite, and lesser hornblende-biotite quartz monzodiorite and biotite quartz monzonite.
  • Age = Late Cretaceous or younger; host is the Late Cretaceous Willow Creek Pluton.
  • Age = Host rock is Late Cretaceous.
