The Goat area is underlain by Devonian metasedimentary and metavolcanic rocks of the Stikine Assemblage. A Late Devonian pluton of McLymont Plutonic Suite consisting of quartz diorite is in contact to the immediate west of the Stikine rock.

The Goat copper-gold occurrence with gold values to 1.3 grams per tonne is hosted within granodiorite, and is associated with shearing and fracturing (Assessment Report 23629).

At the Goat Prospect on the Forrest 2 claim, 1990 field work by Avondale Resources Inc identified an area underlain primarily by intrusive rocks which hosted chalcopyrite and pyrite mineralization. An extensive copper-gold soil geochemical anomaly surrounded this mineralized outcrop. The copper geochemical map indicates an area measuring 200 metres by 200 metres with anomalous values over 166 parts per million copper (Assessment Report 23629).
