Our proposal

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

In doing so, we are seeking approval under the WA Environmental Protection Act 1986 to:

  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 to right); and
  3. Increase the rate of mining to supply up to 2.5 Mtpa of bauxite for export.

The proposal will require clearing of no more than 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.

More details can be found here and in the initial referral document we lodged with the Environmental Protection Authority in June 2020, which can be found here.

We will also be referring the proposal to the Commonwealth Government to decide whether it also needs to be assessed under the Environment and Biodiversity Conservation Act 1999.


Seeking approval for:

  • 5% increase in alumina production at Pinjarra refinery
  • New mining areas of Myara North and Holyoake
  • Mining for 2.5 Mtpa of bauxite for export
