Deposit Type

  • Intrusion related


Summary:

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.
