Mount Holland Expansion Plan Officially Approved, with Project Capacity Set to Double

The expansion adds new mineral resources and replicates the existing complete beneficiation production line. Once completed, annual spodumene concentrates capacity will reach 4.4 million mt, while annual lithium hydroxide production will remain unchanged at 50,000 mt. The mine is held 50/50 by Chile's SQM and Australia's Wesfarmers, with operations managed by their joint venture Covalent Lithium. The expansion is also expected to extend the mine's operational life. Located 400 kilometers east of Perth, the mine commenced production in March 2024. This expansion will further consolidate its position as a core global lithium resources supplier.
