US mining giant Alcoa has decided to abandon its bauxite exploration plans in the Perth Hills, citing feedback from stakeholders and local residents. The company had proposed low-impact strategic drilling in the area, which drew strong opposition due to concerns over drinking water and jarrah forest conservation.
The Shire of Mundaring, a vocal opponent of the plans, described the decision as a 'significant win' for the community. Shire president Paige McNeil said residents had made it clear that exploration posed risks to the biodiverse environment and water security.
Alcoa's director of regulatory approvals, Kane Moyle, acknowledged the community's concerns, stating the company acted in response to the strong feedback. He noted that the drilling was intended to understand the resource better and that no mining plans existed for the area.
Despite this withdrawal, Alcoa continues to pursue other expansion proposals before the state's Environmental Protection Authority, including expanding its Myara North, Holyoake, and O'Neil mining regions, as well as its Huntly and Willowdale mines, and increasing alumina production at its Pinjarra refinery.
The company is exempt from most of Western Australia's environmental legislation and operates under state agreements. Premier Roger Cook said discussions were ongoing to bring Alcoa into a contemporary environmental regime while protecting jobs and the environment.
WA Liberal MP Adam Hort criticized the double standard, noting that recreational activities are restricted in sensitive forest areas, yet industrial drilling was considered. Alcoa said the decision is not permanent and any future proposals would require public consultation.
