Lynas Rare Earths has agreed to invest approximately A$50 million in South Korean permanent magnet manufacturer JS Link, strengthening its position in the downstream rare earth supply chain through a long-term strategic partnership.
The agreement, announced on 7 July, will provide the ASX-listed rare earth producer with an approximately 4.58% fully diluted equity interest in JS Link, which is listed on the KOSDAQ under 127120. The acquired shares will remain under a three-year escrow arrangement, reinforcing the long-term industrial nature of the investment.
Magnet Manufacturing Expansion in Malaysia
As part of its expansion plans, JS Link intends to construct a neodymium-iron-boron (NdFeB) permanent magnet manufacturing facility in Kuantan, Malaysia, with planned production capacity of 3,000 tonnes per year. The facility will be located near Lynas Malaysia’s rare earth separation operations and is expected to create up to 400 jobs.
In addition to the Malaysian development, JS Link operates an existing magnet manufacturing plant in Yesan, South Korea, with current production capacity of approximately 1,000 tonnes per year. The Korean facility is preparing to begin commercial-scale production.
Long-Term Rare Earth Supply Agreement
Under the partnership, Lynas Rare Earths will exclusively supply rare earth materials to both the planned Malaysian plant and JS Link’s existing South Korean facility under an agreement extending through January 2038. The arrangement allows Lynas to expand its involvement in the permanent magnet value chain without developing or acquiring a wholly owned magnet manufacturing business. Through its minority equity position, the company gains strategic participation in downstream manufacturing while limiting direct exposure to production execution and end-market sales.
For JS Link, the agreement secures long-term access to separated rare earth materials supplied by a producer outside China. The partnership also provides Lynas with the opportunity to support future demand for higher-value neodymium-praseodymium (NdPr) products through a customer whose planned production growth is aligned with Lynas’s long-term supply commitments.
Integrated Supply Chains Become a Strategic Focus
Although the A$50 million investment represents a relatively small commitment compared with Lynas Rare Earths’ upstream mining and processing assets, the transaction reflects broader changes in capital deployment across the critical minerals sector.
Rather than relying solely on open-market commodity sales, producers are increasingly combining equity investments, long-term supply agreements and geographically integrated operations to strengthen non-Chinese rare earth supply chains.
The commercial performance of the partnership will depend on the successful commissioning and production ramp-up of JS Link’s Kuantan magnet plant, together with the pace at which customers qualify its permanent magnets for automotive, electronics, defence and industrial applications. While the three-year escrow arrangement and supply agreement running until 2038 provide long-term strategic alignment, they do not remove technology qualification, customer concentration or margin risks associated with downstream magnet manufacturing.
