Our proposal

As part of our desire to keep adding value and to meet contemporary expectations, we are seeking to modernise the environmental approvals for our Huntly Bauxite Mine and Pinjarra Alumina Refinery.

In doing so, we have submitted the following plans for environmental assessment by both the State and Commonwealth:

  1. Increase alumina production at Pinjarra refinery by 5% from 5 million tonnes per annum (Mtpa) to 5.25 Mtpa.
  2. Transition the Huntly mine into the Myara North and Holyoake regions (see map).
  3. Increase the rate of mining to supply up to 2.5 Mtpa of bauxite for export.

The proposal would require clearing of about 6,700 ha of native vegetation within a 42,415 ha development envelope associated with mining and an additional 10 ha of native vegetation associated with the refinery plans. The proposal is in addition to the approximately 200 ha per year that is cleared for the operation of the Kwinana refinery.

See more details below.
