The area is underlain by sediments of the Jurassic to Cretaceous Bowser Lake Group. Auriferous quartz veins are probable sources of placer gold in the Douglas Creek bed. The largest nugget recovered was 195 grams in 1933 (Bulletin 21). Coarse gold has been recovered from gravels above bedrock in the creek bed and from remnants of old channel ground on low bench and bar sections.
Recorded production for the period 1886-1940 totals 10,937 grams of placer gold.
