The Plant will be designed to treat 300 000 tpa of ore to produce a saleable nickel concentrate. The basis for process plant design will be the processing of a supergene ore blend, consideration in design will however also be made for the subsequent processing of a primary ore blend. Blended ore will be processed through a conventional crushing and grinding circuit followed by sequential flotation of the nickel minerals. The ROM ore pad will be managed to facilitate adequate blending of the ore prior to presenting to the plant.

The Plant will consist of run of mine (ROM) ore storage; single stage jaw crushing and crushed ore stockpile; primary grinding using a SAG mill; flotation and concentrate regrinding; concentrate thickening; filtration and storage; tailings thickening, disposal and water return; reagent mixing, storage and distribution; and site services including high and medium voltage power, water and air.
