Geologic descriptionAlluvial deposits at this prospect are underlain by Lower Cretaceous (?) argillite and lithic graywacke (Csejtey and others, 1978). Stream sediment samples contain up to 0.6 part per million silver and 0.8 ppm gold (Kurtak and others, 1992). Two placer claims were staked in 1977.
