The location is accurate within 1/4 mile.

Geologic setting

Geologic description

This prospect is in the Coast Range plutonic-metamorphic complex which consists of high-grade schist and gneiss intruded by Cretaceous and Tertiary granodiorite. The metamorphic rocks are derived from volcanic, pelitic and minor carbonate strata of unknown protolith age (Brew and Ford, 1974, 1984).
The rocks at this prospect include granodiorite, quartz monzonite, and alaskite, and pendants of Eocene pyroclastic volcanic rocks, minor sedimentary rocks, and hornfels derived from pelitic and intermediate to mafic volcanic and volcaniclastic rocks (Brew and Ford, 1985).
Little is known about the prospect; the last reported activity was in 1957 (Wells and others, 1986). The commodities suggest it could be a lead-zinc replacement deposit.
