Comments on the geologic information

  • Geologic Description = Details about the prospect are unavailable. Most likely, a gold-bearing quartz vein(s) cuts 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; the host of mineralization is the Late Cretaceous Willow Creek Pluton.
  • Age = Host rock is Late Cretaceous.
