The proposal is to construct and operate a new concentrate roasting facility 17 km north north-west of the Kalgoorlie Town Centre.

The proposed roaster would be required to treat approximately 190 000 tonnes per annum of concentrate. This would result in the production of 16 000 kg/hr of sulphur dioxide. A concentrate containing typically 27% iron, 33% sulphur and 35 gram per tonne of gold, would be piped as a slurry to the roaster from the proposed Fimiston Plant. The slurry would then be fed into the fluidized bed roaster. The dry calcined product would be repulped for pumping, pre-leached with sodium cyanide, and then run through a carbon absorption circuit. The waste would be pumped to the tailings dam. The gold-loaded carbon would be transported to the proposed Fimiston Plant for recovery of the gold.
