Deposit is a large-tonnage lowgrade disseminated nickel sulphide deposit hosted by olivine cumulate. Mineralisation extends for more than 2 km along strike and to at least 500 m depth. Mineralisation was discovered in 1968 during drilling of an ultramatic outcrop, and after an interrupted history of geophysical surveys, drilling, and surface mapping, together with several changes of ownership, open-cut mining and milling began in 1994: The ore body occurs in the easternmost of three komatiite units in a west-facing sequence of interbedded volcanic rocks, shale, chert, basalt, volcaniclastic rocks, komatiite, layered gabbro, and highMg and tholeiitic basalt.

The sulphides occur as medium to coarse-grained lobate patches interstitial to olivine (now pseudomorphed), as very fine-grained disseminated blebs in olivine, and as fine grained aggregates in cracks, crosscutting veinlets, and along grain boundaries.

Concentration plant with a nominal capacity:
12 Mtpa of ore.

Installing 2 x OK150 tank cells at elevation to minimise pumping costs. Evaluating existing flotation capacity to suit the SSF flowsheet and selecting new duties for the existing cell banks. Extensive flotation floor pump modifications, extensive launder modifications, new samplers and Multi Stream Analyser to provide real time performance data. Minimal tie over time between the old circuit and the new SSF circuit.
