Located 19 km east of Ravensthorpe. Just north of the South Coast Highway.
Prospects almost adjacent to each other. Number 5 is the western most of the two.
Tremolite, talc-carbonate, bladed textured serpentinized olivine, and talc rocks, at the base of a thick sequence of metabasalt, or amphibolite. Banded chert, dipping south, forms the Footwall.
Number 5 is pyrrhotite rich breccia sulphides, grading up to 2.4% Ni. The disseminated sulphides are found in a 2 metre thick zone in carbonate-serpentine-tremolite.
Number 3 is massive pyrite along the basal contact with the ultramafic unit, showing 0.9 metres thick of disseminated sulphides, averaging only 0.51% Ni.
4 valid minerals.
