Geologic setting

Geologic description

This occurrence consists of iron-stained, very fine grained gossan with disseminated pyrite; the gossan is associated with a shear zone in mafic metavolcanic rocks of Paleozoic age (Csejtey and Miller, 1978). A sample of the pyritic gossan contains 1 part per million silver and 0.05 part per million gold (Miller and others, 1978).
