The partnership's focus on supporting viable Western mining operations and creating more balanced global markets for critical minerals directly benefits Pilbara Minerals by reinforcing demand and stability. Similarly, companies involved in expanding lithium hydroxide and carbonate processing capacity within Australia are poised for growth, transforming Australia's raw material dominance into downstream processing capabilities.
For rare earth elements, the partnership directly targets China's overwhelming control of processing and refining. Lynas Rare Earths (ASX: LYC), as the only significant rare earth producer outside Chinese control, holds a unique strategic position. It produces neodymium-praseodymium (NdPr), crucial for EV motors and wind turbines, and achieved a significant milestone in May 2025 by producing commercial quantities of dysprosium oxide outside China. Lynas has also inked a memorandum of understanding with US-based Noveon Magnetics to develop a scalable US supply chain for rare earth permanent magnets. Other key beneficiaries include Arafura Rare Earths (ASX: ARU), whose Nolans Project in the Northern Territory, focusing on light rare earths like NdPr, is construction-ready and has secured substantial government funding, including an A$200 million injection from Australia's National Reconstruction Fund Corporation and a US$100 million equity investment from the Australian government, alongside EXIM financing. Iluka Resources (ASX: ILU), with its established mineral sands production, is developing rare earth refining capabilities at Eneabba, Western Australia, backed by a A$1.25 billion government loan, with first production expected in 2027. Northern Minerals (ASX: NTU), with its Browns Range Project focusing on heavy rare earths like dysprosium and terbium, is also a recipient of EXIM financing, highlighting its strategic importance for defense and high-temperature magnet applications. Additionally, VHM, with its project in Victoria, will supply rare earth elements, zircon, and titanium minerals, contributing heavy rare earth feedstock for supply-chain resilience. Beyond these major players, the US Department of Defense is investing in a 100-metric-ton-per-year gallium refinery at Alcoa's (ASX: AWC) Wagerup facility in Western Australia, with Australian government investment of up to US$200 million, further diversifying the critical minerals landscape.
