Project Proponent Worsley Alumina Pty Ltd Proposal description The proposal is to upgrade the existing Mine facilities by increasing the maximum daily process from 8 000 tonnes to 12 000 tonnes. Ore would continue to be mined from the same orebody currently being mined. It is therefore expected that the proposed increases in the rate of production would shorten the overall project life from fifteen to possibly ten years. The plant facilities required for the upgrading would be an additional crusher, a ball or semi-autogenous grinding mill, additional classification cyclones and a leach tank. Residue transfer pumps would also require upgrading. It is proposed that other areas of the plant would remain the same, and no additional clearing beyond the existing plant site perimeter would be required.
