Worsley Alumina

Western Australia

µç¾º²©²ÊÂÛ̳ owns 86 per cent of Worsley Alumina, with 10 per cent held by Japan Alumina Associates (Australia) Pty Ltd and the remaining 4 per cent held by Sojitz Alumina Pty Ltd. Operations began in 1984 and today, it is recognised as one of the largest alumina refineries in the world.

Bauxite is mined near the town of Boddington, 130 kilometres south-east of Perth. It is transported by overland conveyor to the alumina refinery near Collie and turned into alumina powder, before being transported by rail to the Bunbury port.

It is then shipped to smelters around the world, including µç¾º²©²ÊÂÛ̳’s Hillside and Mozal aluminium smelters in Southern Africa.

Cannington

Queensland, Australia

Cannington consists of an underground hard rock mine and surface processing facility, a road-to-rail transfer facility and a concentrate handling and ship loading facility at the Port of Townsville. In Q4 FY22 we transitioned to 100 per cent truck haulage to bring product to the surface.

Silver, lead and zinc are extracted from the ore using grinding, sequential flotation and leaching techniques that produce high-grade, marketable lead and zinc concentrates with a high silver content.
