Lynas reached an agreement to purchase the Mount Weld rare earths project, shifting the company’s focus from gold toward rare earth development. This deal set the foundation for building an integrated supply chain: mining and concentrating ore in Western Australia, then processing it into separated products elsewhere.
After acquiring Mount Weld, the company changed its name to Lynas Corporation Limited. The renaming signaled a strategic commitment to rare earths as a long-term business, rather than a side activity.
A feasibility study for developing Mount Weld was completed, providing a detailed technical and cost basis to move toward mine construction. This was a key step for raising finance and planning how to turn the deposit into saleable concentrate for downstream processing.
A proposed funding deal involving China Non-Ferrous Metal Mining (Group) Co. that would have taken a controlling stake in Lynas was not approved by Australia’s Foreign Investment Review Board. The decision reflected concerns about control of strategic mineral supply and pushed Lynas to seek other financing.
Lynas signed a strategic alliance with Japan’s Sojitz to support offtake and broader project financing, aiming to diversify Japan’s rare earth supply away from heavy dependence on China. The agreement strengthened Lynas’s market pathway before large-scale production began.
With the concentrator operating, Mount Weld began shipping rare earth concentrate for downstream refining, connecting the Western Australia mine to the planned processing hub in Malaysia. This step mattered because concentrate shipment is what enables separation into individual rare earth products used by manufacturers.
Western Australia’s Premier officially opened the Mt Weld rare earth mine, marking the move from development to an operating mine. The project was widely framed as an important non‑China source of rare earth concentrate for global high-tech supply chains.
Malaysia’s Atomic Energy Licensing Board issued a temporary operating licence for the Lynas Advanced Materials Plant (LAMP) in Kuantan, a major regulatory milestone amid public debate. The licence allowed Lynas to move closer to processing Mount Weld feed into separated rare earth products.
LAMP began operations in late 2012, starting the transition from construction to producing separated rare earth products outside China. The start was significant because separation (using processes like solvent extraction) is the most complex and value-adding part of the rare earth supply chain.
Lynas announced it had produced its first rare earth products at LAMP, moving from commissioning to saleable output. This helped establish Lynas as a major producer of separated rare earths outside China, using Mount Weld feedstock as the upstream source.
Malaysia extended Lynas’s licence to import and process rare earths until March 2026, after Lynas proposed a method aimed at reducing radioactive waste concerns linked to thorium. The extension came with conditions, showing that regulatory approval remained tied to waste handling and process changes.
Lynas opened its Kalgoorlie rare earth processing facility in Western Australia, part of a plan to move more processing steps into Australia. The site produces mixed rare earth carbonate for shipment to Malaysia for separation, reducing reliance on Malaysia for earlier-stage processing steps.
Recurring power outages in the Kalgoorlie region led Lynas to downgrade production expectations, highlighting infrastructure risk in building domestic processing capacity. The disruptions mattered because stable utilities are essential for continuous chemical processing and supply-chain reliability.
By early 2026, Lynas’s Malaysian operating licence was set to expire in March 2026, keeping long-term operations dependent on meeting Malaysia’s conditions around waste and processing steps like cracking and leaching. This point marks an unresolved outcome: Lynas had expanded processing in Western Australia, but the final balance between Malaysian and Australian processing remained shaped by regulation and infrastructure performance.
