Geology: Narrow auriferous arsenopyrite-quartz-scorodite veins occur in and near a limonite-stained dike in altered and contorted graywacke-argillite country rock; samples contained from 0.5 to 48 ppm Au (Foster, 1968). Joesting (1942, ATDM Pamph. 1), reported a mineralized zone in a cut bank that contains stibnite and traces of cinnabar and gold.
Workings: Amax Gold Exploration, Inc., drilled on the Lillian Creek property in 1990 (Swainbank and others, 1991).
Alteration: Dike is limonite-stained.
