Australia’s lithium sector is emerging as a key winner from efforts to diversify critical minerals supply chains away from China’s dominance in spodumene conversion and cathode materials. New offtake and joint venture structures are shifting some refining and hydroxide production capacity from Chinese hubs in Jiangsu and Sichuan to Australian-linked projects in Western Australia, including integrated mine–refinery developments near Kwinana. For geotechnical and mining teams, this points to sustained demand for hard‑rock pit expansions, tailings storage upgrades and supporting port and rail capacity over the medium term.

Dewatering of the main pit at Rox Resources’ Youanmi gold project in Western Australia has been completed, exposing the historic Youanmi underground workings for the first time in decades and clearing the way for decline access. The work allows detailed geotechnical mapping of existing drives and stopes, assessment of ground conditions around legacy voids, and planning of new underground infrastructure tied to the existing shaft and portal locations. Engineers will now be able to refine support regimes, groundwater management and backfill strategies based on direct inspection rather than historic records.

Western Australian gold producers reported stronger March-quarter output, with established operations such as Kalgoorlie and Boddington lifting mill throughput and improving head grades despite persistent labour and energy cost pressures. Developers advanced expansion projects including new open-pit cutbacks and underground declines, alongside incremental plant upgrades such as additional leach capacity and improved gravity circuits. Exploration drilling around existing pits and along greenstone belt extensions continued to grow resource potential, extending mine lives and supporting long-term planning for tailings storage and haulage infrastructure.
