Several shallow laterite nickel pits north of the main processing plant.
The North prospect shows unusual replacement type sulphides, found in a shallow supergene zone, in altered unlayered olivine rocks, immediately above a thin sheet like intrusion of country rock. The primary assemblage is pyrrhotite-magnetite-pyrite-chalcopyrite-pentandite, unusual as it is pseudomorphic after primary olivine grains of irregular fracture networks.
Later during metamorphism, recrystallization of serpentine and the growth of fibrous tremolite and chlorite penetrated the assemblage. In the supergene zone, pyrrhotite has been locally altered to pyrite and marcasite, with pentlandite largely replaced by cupriferous violarite. In the oxidised zone above, chalcopyrite has been replaced to varying degrees by microcrystalline chalcosine-covelline-goethite aggregates and magnetite replaced by hematite.
