A nickel mine located about 25 km North-east of Kambalda. Alternatively it can be reached by travelling along a road south of the Mount Monger pastoral station homestead.
The nickel deposit was discovered in 1974, and mined as a joint venture between Western Mining Corporation and BHP from 1980 to 1999, when the known ore resource was exhausted. View Resources conducted limited mining of the remnant ore across 2004 to 2005. Late June 2006 a new orebody was discovered under the existing mined resource and in 2008 the mine was re-opened. It is a joint venture between Mincor Resources and View Resources.
The original mine accessed high grade nickel at 10-16% Ni. The massive mineralisation occurs in a 20 metre thick low Mg amphibolite-chlorite altered picrite-pyroxenite unit, which underlies a sharp contact, unmineralised high Mg-talc-chlorite altered komatiite olivine cumulate. It lies within the Golden Ridge-Carnilya Hill Belt, which also contains the Blair deposit.
Mineralisation is contained in small lenses of massive and matrix sulphides, 1-2 metres thick, extending a length of 450 metres, but only down to 150 metres below the surface.
Primary sulphide is pyrrhotite, with lesser pentlandite, minor chalcopyrite, pyrite, chromite, magnetite, ilmenite, rare niccolite, gersdorffite and bravoite, trace sphalerite, galena, and un-named telluride minerals. The pyrrhotite may contain deformation twins and kink banding, or polygonal aggregates. Chromite and magnetite form a thin layer at the base of the massive sulphides, or at the massive-matrix boundary.
The source compares the deposit for its style and setting to the nickel deposits at Kambalda, although Carnilya is smaller.
