Geologic setting

Geologic description

This occurrence consists of bornite in quartz-epidote veinlets in biotite-hornblende quartz diorite, probably of Tertiary or Cretaceous age (Clark and others, 1970 [OF 70-73]). A sample contained 100 parts per million (ppm) copper, 10 ppm silver, and 0.6 ppm gold.

Mineral deposit model Bornite veinlets in quartz diorite.
Age of mineralization Veinlets are younger than the quartz-diorite host rock, which is probably of Tertiary or Cretaceous age.
Alteration of deposit Deposit consist of veinlets of quartz and epidote with bornite in quartz diorite.
