Geologic setting

Geologic description

This occurrence consists of placer gold and garnet-rich black sand in 2 adjacent creeks. Bedrock is not exposed nearby but the upper parts of the creeks drain the contact between Middle to Upper Jurassic granodiorite migmatite and Upper Jurassic trondhjemite (Csejtey and others, 1978). Panned-concentrate samples concentrates have more than 10,000 parts per billion gold. Samples from the east creek have 0.566 ounce of gold per ton and 6 colors in the pans; samples from the west creek contain 0.532 ounce of gold per ton and have 5 colors in the pan (Clautice and others, 1990).
