Liontown backs a bigger, lower-cost Kathleen Valley lithium operation

Liontown Limited (ASX:LTR) has committed $389 million to expand its Kathleen Valley lithium operation, betting that more tonnes and lower costs will strengthen the Western Australian mine through the lithium cycle. The board-approved project targets average spodumene concentrate production of about 780,000 dry metric tonnes a year from FY30, with output expected to peak above 800,000 dmt in FY34.

Kathleen Valley capacity moves from 2.8 Mtpa to 4.2 Mtpa

The expansion will lift ore processing capacity from approximately 2.8 million tonnes a year to 4.2 Mtpa, while the mining rate is expected to reach about 4.1 Mtpa on average from FY30. Liontown plans to accelerate development of the Kathleen’s Corner underground mine alongside Mount Mann, with an optimised design expected to reduce underground development by roughly 45,000 metres.

At the processing plant, the main additions include a new ball mill, upgraded magnetic separation, improvements to the tailings system, pumps and piping, and a dual-train paste plant. The wider infrastructure package also covers power distribution, water, accommodation and related site upgrades. Early works have started and long-lead equipment, including the ball mill, has been ordered, with completion scheduled by the end of Q2 FY29 and first incremental tonnes targeted in FY28.

Lower forecast costs come with a larger capital bill

Liontown forecasts five-year average unit operating costs of A$840-A$920 per dmt sold on a free-on-board basis from FY30, alongside annual sustaining capital of A$90 million-A$100 million. The company estimates an undiscounted payback period of about 2.5 years from construction completion. Those figures are based on a long-term spodumene concentrate price of US$1,495 per dmt on a CIF basis, a 0.73 Australian dollar-US dollar exchange rate and a target average plant recovery of 78%.

The $389 million expansion estimate includes contingency and the A$60 million-A$70 million of previously announced FY27 expansion expenditure, but is stated in real Australian dollars and excludes general inflation. It comprises A$145 million for mining, A$137 million for processing and A$107 million for non-process infrastructure. FY27 total capital expenditure guidance consequently rises from A$320 million-A$370 million to A$435 million-A$495 million, while production guidance of 390,000-440,000 dmt and unit cost guidance of A$1,050-A$1,250 per dmt remain unchanged.

Funding depends on cash flow and lithium prices

Liontown intends to fund the project from existing cash and operating cash flow, based on its consensus pricing forecast. The company says it had A$561 million in cash at the end of June 2026 and retains the ability to reassess, defer or stop activities if market conditions change. The additional production is currently uncommitted, leaving scope for spot sales, customer prepayments or new offtake contracts linked to a spodumene price index, but no new offtake agreement has been announced with the FID.

The key qualification is geological as much as financial. The production inventory supporting the expansion comprises 6% proved ore reserves, 72.5% probable reserves and 21.5% inferred mineral resources. Liontown says less than 9% of the inferred material is scheduled to be mined in the first five years, which is intended to cover the estimated payback period, and says the inferred component does not materially affect technical or economic viability. That remains a lower-confidence category, however, and the company also flags permitting for water, wastewater and native vegetation activities alongside the familiar risks of ramp-up, recoveries, costs and lithium prices. The expansion now has board approval; the more revealing test will be whether the mine can add tonnes on schedule without allowing the capital envelope to drift.
