Geologic setting

Geologic description

Placer gold occurs along a small drainage in a sinuous strip 8-10 feet wide (Smith, 1925). Bedrock is about 2 feet below a covering of gravel and large boulders. The source of the gold is apparently from gold-sulfide bearing quartz stringers in the area (see Cape Kubugaki Lode, ARDF No. KR002). The best pay was found just downstream from outcropping quartz stringers. Total production between 1915 and 1925 is estimated at 160 ounces.
