Geology: This occurrence consists of north-northeast striking quartz-gossan veins that occur in an altered olivine basalt dike and in a shear zone that cuts shale and sandstone of the Upper Cretaceous, Kuskokwim Group (Bundtzen and others, 1998). Cady and others (1955) show a lode gold occurrence on the edge of the flood plain of the Kuskokwim River, about 1.0 mile to the south which may be along the same structural trend. Samples from this occurrence contained 9 parts per billion (ppb) gold, 900 ppb silver, and 700 parts per million (ppm) zirconium (Bundtzen and others, 1998) There is no known source for the zirconium.
Workings: Cady and others (1955) show a lode gold occurrence on the edge of the flood plain of the Kuskokwim River, about 1.0 mile to the south. The occurrence was sampled by Bundtzen and others (1998).
