Geologic setting

Geologic description

This occurrence consists of auriferous, sulfide-bearing, sheeted quartz veins up to 1.2 inches thick in Jurassic granodiorite. The veins contain fine-grained pyrite and minor tourmaline. Samples taken by Church, Riehle, and Goldfarb (1993) contain up to 4.4 parts per million (ppm) gold but most samples have 50 to 450 parts per billion gold, and up to 20,000 ppm copper, 700 ppm cobalt, 200 ppm silver, and 100 ppm lead.

Mineral deposit model Polymetallic vein, epithermal gold vein (Cox and Singer, 1986; model 22c, 25).
Mineral deposit model number 22c, 25
Age of mineralization Jurassic or younger; the sheeted quartz veins cut Jurassic granodiorite.
