Located 23 km south of Karratha.
Layered intrusions predominantly gabbro and plagioclase bearing pyroxenite forming a thin marginal envelope to interlayered periodotite and pyroxenite. Disseminated and massive sulphides are located near the base contact, and massive sulphides are concentrated in depressions along the basal intrusive contacts beneath a sequence of mafic and ultamafic cumulates.
Explored by Westfield early 1970's. Chalcopyrite, pyrrhotite, and pentlandite as lobate aggregates in a wedge shaped mass at the apex of an intrusion.
7 valid minerals.
