Geologic setting

Geologic description

The rocks in the vicinity of the Old Gold prospect are Jurassic granodiorite (Csejtey and others, 1978). Two claims were staked in 1978. The prospect consists of iron-stained and clay-altered, quartz diorite exposed in a saddle near the top of a ridge (Kurtak and others, 1992). Nine grab samples collected by the U.S. Bureau of Mines contain up to 90 parts per billion gold and 0.5 part per million silver (Kurtak and others, 1992).
