Prospect Located 83 km east of Kalgoorlie.

Percussion and diamond drilling encountered thin intervals of nickel sulphide veins, veinlets and disseminations, the best intersection being a drilled width of 3.05 m averaging 1.1 per cent nickel and 0.63 per cent copper (DDH CD3) at a vertical depth of 46 m. The sulphides consist of pyrrhotite, pyrite, marcasite, violarite, chalcopyrite, cubanite, bornite and covellite associated with small dykes of olivine
micropyroxenite and basalt which appear to be derived from
subjacent and adjacent olivine gabbroid of the Celebration
Dyke. The ultramafic rock which these small dykes penetrated was probably a serpentinite altered to an olivine-orthopyroxene-magnetite hornfels during emplacement of the Celebration Dyke.
