Discovered in the 1970's 4.5 kilometres north-east of the old Hales Grave Well, near the old Lionel asbestos mining area, 25 kilometres north of Nullagine.
The material has been marketed as 'Pilbara Jade', but it is a chloritic serpentinite, that may contain irregular patches of fibrous serpentine. It is fine grained, massive, green to grey-green rock almost entirely composed of chlorite. The material often has minor translucence near the surface.
It is found within a group of Archean, metamorphosed mafic and ultramafic rocks of the Dalton Suite.
The deposit also contains irregular white fibrous veins of Al-serpentine in the massive green chlorite. These veins are cut by pale yellow-green, sub-parallel chrysotile serpentine fibres.
'Pilbara jade' occurs in kidney shaped bodies or narrow dykes in serpentine. The material is often fractured near the surface.
It is sold locally as slabs,and made into carvings and other objects.
The Mindat co-ordinates are the Lionel copper deposit, however the 'jade' location is probably one of the outlying deposits mentioned in this article, likely associated with, or near the asbestos/chrysotile mine.
