Lindian Resources has secured exclusive rights to over 13,000 tonnes of heavy rare earth feedstock in Kazakhstan, aiming to boost output at its wholly owned SARECO processing facility with dysprosium, terbium, and yttrium-rich material.
- Exclusive option on 13,389 tonnes of heavy rare earth stockpile
- Rights to evaluate additional 15,000–20,000 tonnes without upfront cost
- Potential to produce mixed heavy rare earth carbonate including Dy, Tb and Y
- Established rail logistics from Aktau to Stepnogorsk facility
- Complementary to Kangankunde NdPr concentrate, enhancing rare earth value chain
Strategic Heavy Rare Earth Feedstock Secured
Lindian Resources (ASX:LIN) has taken a significant step in its rare earths strategy by securing an exclusive option to acquire 13,389 tonnes of heavy rare earth element (HREE) feedstock from a stockpile in Aktau, Kazakhstan. This material, rich in dysprosium (Dy), terbium (Tb), and yttrium (Y), is earmarked for processing at Lindian's 100%-owned SARECO Mixed Rare Earth Carbonate (MREC) hydrometallurgical facility in Stepnogorsk.
The agreement with Summit Atom Rare Earth Company LLP not only covers the existing stockpile but also grants Lindian exclusive rights to evaluate an additional 15,000 to 20,000 tonnes of unextracted material over a 12-month period, with no upfront cash required. This could potentially expand Lindian's feedstock access to over 28,000 tonnes, subject to successful evaluation and regulatory approvals.
Complementing Kangankunde with Heavy Rare Earths
Lindian’s Executive Director Zac Komur highlighted the strategic importance of Aktau’s feedstock, noting its historical role supplying SARECO and its potential to broaden Lindian’s rare earth product suite. While the Kangankunde project in Malawi provides strong exposure to light rare earths neodymium and praseodymium (NdPr), the Aktau stockpile offers a pathway to heavier, more strategically critical rare earths like Dy and Tb, essential for high-performance permanent magnets used in defence, aerospace, and electric vehicles.
Yttrium, another key element in the stockpile, has applications in advanced ceramics, electronics, and thermal barrier coatings, with supply outside China remaining limited. Confirming recoverable quantities of these elements would enhance Lindian’s integrated light and heavy rare earths value chain, positioning SARECO as a flexible, multi-feed processing platform.
Logistics and Processing Potential
The Aktau stockpile benefits from an established rail corridor connecting Aktau to Stepnogorsk via Kazakhstan Temir Zholy’s national network. This corridor was historically used to transport feedstock to SARECO, reducing logistical hurdles for Lindian. Of the initial 13,389 tonnes, 7,549 tonnes are ready for transport, with the remainder undergoing drying.
Metallurgical testwork is underway to verify the stockpile’s composition and processing suitability. While no mineral resource or ore reserve has been defined yet, positive results could enable earlier utilisation of the SARECO facility, potentially processing Aktau feedstock ahead of or alongside Kangankunde concentrate deliveries.
Market Dynamics and Pricing Upside
The timing of this feedstock acquisition is notable given the concentrated global supply of Dy, Tb, and Y. Combined production by major players Lynas and MP Materials is under 100 tonnes annually, against a total dysprosium-terbium market of approximately 3,455 tonnes. Forecast prices for these elements are significantly higher than current spot prices, with dysprosium and terbium expected to trade at US$541/kg and US$1,988/kg respectively, offering potential upside if Lindian can commercialise the Aktau feedstock effectively.
This acquisition aligns with Lindian’s recent milestones, including securing 100% ownership of SARECO and progressing the Kangankunde project toward first production in Q4 2026, backed by substantial capital raises and strategic partnerships. The Aktau feedstock could provide a geographically concentrated, near-term supply route for heavy rare earths, enhancing Lindian’s competitive positioning in critical minerals supply chains.
Bottom Line?
Lindian’s exclusive option over the Aktau heavy rare earth stockpile could accelerate SARECO’s utilisation and diversify its product mix, but final economics hinge on pending metallurgical results and regulatory approvals.
Questions in the middle?
- Will metallurgical testwork confirm economically recoverable Dy, Tb, and Y grades in the Aktau stockpile?
- How quickly can Lindian secure subsoil rights and regulatory approvals to unlock the additional 15,000–20,000 tonnes?
- What impact will integrating Aktau feedstock have on the timing and scale of SARECO’s production alongside Kangankunde concentrate?
