Alteration

  • (Local) Wall-rock alteration within a few inches of the vein is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).

Comments on the geologic information

  • Geologic Description = At least one foot of 'good ore' contains chalcopyrite, pyrite, galena, and free gold on surface (Capps, 1919). An 8.5 ft wide pegmatitic vein strikes N 55 W, and dips 55 SE. The coarse, border material consists of quartz, orthoclase, muscovite, and particles of chalcopyrite along the borders. Central part of vein is milky quartz cut by irregular stringers of chalcopyrite and a little bornite (Chapin, 1921). ? Country rock is the Late Cretaceous Willow Creek Pluton, 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. Wall-rock alteration within a few inches of the vein is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).
  • Age = Late Cretaceous or younger; the mineralized host is the Late Cretaceous Willow Creek Pluton.
  • Age = Host rock is Late Cretaceous.

Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Willow Creek

Comments on the workings information

  • Workings / Exploration = Three claims first staked in 1917 on surface expression of 1 ft of 'good ore'. Very little development reported, the prospect was explored in one place by an open-cut across vein Chapin (1921).
