Lindian Resources (ASX: LIN) has locked in exclusive access to a 13,389-tonne heavy rare earth stockpile in Kazakhstan, at zero upfront cost, reopening the original feed route that once kept SARECO’s processing plant running.
Lindian’s Kazakh entity, Silkway Metals LLP, has signed a Stockpile Access and Option Agreement with Summit Atom Rare Earth Company LLP. The deal, filed with the ASX on 31 August 2026, covers ore already extracted and sitting at Aktau.
What Lindian wants out of it: dysprosium, terbium, and yttrium. Three heavy rare earth elements where combined Western production currently amounts to fewer than 100 tonnes per year against a global DyTb market of approximately 3,455 tonnes.
SARECO’s Original Feed Route, Reopened
Lindian acquired 100% of the SARECO Mixed Rare Earth Carbonate hydrometallurgical facility in Stepnogorsk on 10 August 2026, paying up to US$20 million in cash.
SARECO is one of very few commercial-scale MREC facilities outside China with an actual operating history, sitting alongside Lynas, MP Materials, and Serra Verde in a very short list.
The detail most coverage will skip is this: Aktau material was historically used as feedstock for SARECO when the plant operated under its original Kazatomprom and Sumitomo Corporation joint venture. Lindian is not proposing a first-of-kind logistics experiment. The Company is re-establishing a supply route that literally kept SARECO running before it went dormant.
The Aktau to Stepnogorsk rail corridor runs through Kazakhstan’s national rail network, KTZ, and was used for exactly this purpose during SARECO’s prior operating period. The logistics path already exists. That reduces a risk category junior mining investors routinely underestimate: the cost and complexity of moving bulk material for the first time.
The Aktau to Stepnogorsk rail corridor, previously used to transport feedstock to SARECO during its original operating period.
Of the 13,389 tonne initial parcel, 7,549t is identified as prepared for transport. The remaining 5,840t is currently drying before dispatch. There’s also a 12-month window during which Lindian can require Summit to chase the subsoil rights on a further 15,000 to 20,000 tonnes of ore that hasn’t been extracted yet. If that comes through, total access could reach north of 33,000 tonnes. Still no upfront cash required.
The Lindian Resources Rare Earth Pipeline Hits an Exceptional Supply Gap
The market backdrop is not subtle. China placed export licensing requirements on seven heavy rare earth elements in April 2025, covering terbium, dysprosium, and yttrium among others. What followed was a sharp contraction in supply available to Western manufacturers and a corresponding widening of price spreads between Chinese domestic benchmarks and ex-China markets.
S&P Global’s Platts has noted that yttrium, terbium, and dysprosium carry the sharpest price premiums outside China, with defence and aerospace demand keeping pressure on supply. No significant non-Chinese production is expected before 2027.
The gap between spot and Western forecasts in Lindian’s announcement says the rest. Dysprosium spot is US$249/kg. Western forecast: US$541/kg. Terbium spot is US$1,127/kg. Western forecast: US$1,988/kg. Those gaps exist because verified, qualifiable, non-Chinese supply commands a premium that Chinese spot simply does not reflect.
Yttrium is the overlooked element in this deal. Forecast price: US$383/kg. Current spot: approximately US$10/kg. Lynas has scheduled first yttrium production for early calendar 2028, and no credible Western yttrium capacity is currently online at commercial scale.
If Aktau testwork confirms recoverable yttrium within the ore profile, the revenue arithmetic of this deal changes considerably relative to any comparable ASX-listed HREE play.
Western forecast vs spot price comparison (Aktau target elements):
| Element | Western Forecast Price | Current Spot Price |
|---|---|---|
| Dysprosium (Dy) | US$541/kg | US$249/kg |
| Terbium (Tb) | US$1,988/kg | US$1,127/kg |
| Yttrium (Y) | US$383/kg | ~US$10/kg |

Zero Upfront Cash, Real Conditions Still Attached
The deal structure is clean. No cash changes hands for the exclusivity period or the option itself. Silkway Metals holds irrevocable and exclusive rights to evaluate the stockpile, sample it, assess metallurgy, and decide whether to exercise the option, all without paying to hold those rights during the 12-month period.
For a company simultaneously directing construction funds toward Kangankunde in Malawi and SARECO recommissioning in Kazakhstan, preserving capital while securing exclusive access is good housekeeping.
But the conditions are real and worth stating plainly. No Mineral Resource or Ore Reserve has been defined for the Aktau stockpile. The presence, grade, and metallurgical recovery of the HREE mineralisation have not yet been confirmed. Sampling and metallurgical testwork are underway, with initial results expected in the coming months. No specific date is given.
That extra material hasn’t been dug up yet and the subsoil rights sit with the Kazakhstani state. Summit needs regulatory approval before Lindian can touch it. Subsoil use rights must be obtained by Summit applying for a contract extension. The timeline and outcome of that regulatory process carry genuine uncertainty. The announcement does not suggest otherwise.
This deal secures optionality over a genuine opportunity. An investor who treats the upper-end 33,000 tonne figure as already banked is reading ahead of the evidence currently on the table.
Where This Sits Inside Lindian’s Broader Rare Earths Supply Chain
Lindian’s existing investment case centres on neodymium and praseodymium from Kangankunde, the light rare earths that underpin permanent magnet production for EV drivetrains and wind turbines.
The Kangankunde Rare Earths Project in Malawi carries a 261 million tonne resource at 2.14% TREO, with first ore feed targeted for Q4 2026. A$191.5 million in institutional capital and a 15-year offtake and loan agreement with Iluka Resources put Stage 1 development well into execution, not planning.
Pull off the Aktau deal and SARECO ends up processing both NdPr from Kangankunde and heavy rare earths from Aktau through the same facility. NdPr covers the light end of the magnet supply chain. Dy, Tb, and Y cover the heavy end. Very few producers outside China can claim both.
That combination is genuinely scarce among ex-Chinese producers. Australia’s broader rare earths sector has been building toward integrated supply chain thinking for years, but operational hydrometallurgical infrastructure aligned to confirmed feedstock remains in very short supply globally.
Victory Metals’ North Stanmore Project demonstrates the depth of Australian HREE project development, with terbium and dysprosium grade boosts already recorded. Critica’s Jupiter clay resource is building scale in Queensland. Neither has an operational processing facility matched to their feed. That point of distinction belongs to Lindian, conditional on SARECO reaching commercial throughput.
Inbound interest from customers and strategic counterparties in the United States, Europe, and Japan was flagged at the time of the SARECO acquisition announcement. A DyTbY product stream would open a distinctly different set of procurement conversations with those buyers, particularly in US defence supply chains where domestic antimony and rare earth sourcing is now a bipartisan legislative priority.
The Aktau announcement is neither confirmed value nor promotional speculation. It is an intelligently structured option over historically relevant material, obtained at zero upfront cost, that could add a second high-value product stream to a processing facility that was already built for exactly this feed. Testwork results will tell the rest of the story.
