South32, Australia's Worsley Alumina operation, gets approval from the federal government

South32, a mining company in Australia, announced on Wednesday that the federal government had granted environmental approval to its Worsley Alumina plant in Western Australia for it to be extended.

South32 is the owner of 86% of Worsley Alumina. Worsley Alumina began operating about 41 years ago, and it's one of the largest alumina refineries in the world. Japan Alumina Associates owns 10%, and Sojitz Alumina holds the remaining 4%.

South32, a Perth-based company, has announced that it is moving forward with the development of new bauxite mine areas. These are expected to support production at least through fiscal year 2036.

The company's shares fell by up to 1.5%, reaching A$3.380. If the current trend continues, the company is on course for a third straight session of losses. As of 0231 GMT, the benchmark ASX200 index was up 0.3%.

The miner has received approval for the expansion of Worsley Mine in December 2024 from Western Australia.

South32 began the environmental approval process in 2019 with the Western Australian Environmental Protection Authority, aiming to obtain the green light for mining more bauxite south of Perth.

The Environmental Regulator approved the proposal in July last year, but with several conditions because of the sensitive nature the forest area that will be mined.

The miner carried out a value-based assessment of the project, and recognised a $554 million impairment charge on its Worsley Alumina Mine in relation to conditions stipulated by the WA EPA.

According to the annual report of the miner, the company produced 5.1 millions tons of alumina during fiscal 2024. The commodity contributed around 19% to the group's earnings, before interest, taxes and depreciation.
