Bauxite Mining

In 1961, the State Government and Alcoa entered into an agreement allowing Alcoa to mine and refine bauxite within a defined Mineral Lease on the Darling Range extending from east of Perth to Collie.
In 1994 the lease was reduced to 7,129 sq km to remove areas where bauxite mining would not occur. Alcoa does not mine in old growth forest. Alcoa’s first mine, at Jarrahdale, began operations in 1963 and for 35 years, until its closure in 1998, was the only source of bauxite for Alcoa’s alumina refinery at Kwinana.
Alcoa currently operates two bauxite mines within its Western Australian Mineral Lease. The Huntly mine, established in the early 1970s is located near Dwellingup and is the world’s largest bauxite mine, supplying bauxite ore to the Pinjarra and Kwinana Refineries. The Willowdale mine is located east of Waroona and supplies bauxite ore to the Wagerup Refinery.
The state agreement act and its subsequent amendments is the legislation under which Alcoa operates today. Alcoa’s operations are overseen by the Mining and Management Program Liaison Group (MMPLG), chaired by the Department of Industry and Resources, on behalf of the Minister for State Development, with representatives from the Department of Environment and Conservation (DEC), the Department of Water (DoW). The MMPLG is responsible for reviewing mine plans and associated activities and making recommendations to the Minister for State Development.
