Liontown Greenlights $389M Expansion to Lift Lithium Output 50% by FY30
Key Takeaways
- Liontown's Board has approved a $389 million FID to expand Kathleen Valley's processing capacity from 2.8 Mtpa to 4.2 Mtpa, targeting a five-year steady-state average of 780,000 dmt of spodumene concentrate per annum from FY30.
- Peak production of over 800,000 dmt is forecast for FY34, representing a greater than 50% lift on Liontown's current production trajectory.
- The expansion is fully self-funded from Liontown's $561 million cash balance (as at end of June 2026) and operating cashflow — no equity raise is required.
- Undiscounted payback from incremental cashflows is forecast at approximately 2.5 years from the end of construction, with completion scheduled for end of Q2 FY29.
- FY27 total capital expenditure guidance has been revised upward to $435–$495 million to incorporate $175–$195 million of expansion capital now scheduled in FY27, while production and unit cost guidance remain unchanged.
Board greenlights Kathleen Valley expansion, targeting 780,000 dmt a year
Liontown Limited (ASX: LTR) has had its Board approve the Final Investment Decision (FID) to expand the Kathleen Valley Lithium Operation, targeting a five-year steady-state average of approximately 780,000 dmt of spodumene concentrate (SC5.4 basis) per annum from FY30, with production anticipated to peak at over 800,000 dmt in FY34.
That output represents a greater than 50% lift on Liontown’s current production trajectory, with ore processing capacity expected to increase from approximately 2.8 Mtpa to 4.2 Mtpa. Total approved capital for the expansion is $389 million (inclusive of previously announced FY27 expansion expenditure of $60–70 million and contingency), with construction already commenced under early works and completion scheduled for the end of Q2 FY29.
Tony Ottaviano, Managing Director and CEO
“The Kathleen Valley Expansion is expected to lift our concentrate production by over 50% to a five-year average of 780,000 dmt from FY30, making Kathleen Valley one of the most significant hard-rock operations in the world.”

Expansion parameters and capital breakdown at a glance
The key parameters underpinning the expansion are summarised in the table below.
| Parameter | Unit | Value |
|---|---|---|
| 5-year avg. production from FY30 (SC5.4 basis) | kdmtpa | ~780 |
| Peak production (FY34) | dmt | >800,000 |
| Processing capacity (post-expansion) | Mtpa | 4.2 |
| Total approved capital | A$m | 389 |
| Target unit operating cost (FY30–34) | A$/dmt sold FOB | $840–$920 |
| Sustaining capital (FY30–34 avg.) | A$m/year | $90–$100 |
| Undiscounted payback (from end of construction) | Years | ~2.5 |
The $389 million capital estimate breaks down across three categories:
- Mining ($145 million): pre-production mine development, resource definition drilling, and enabling infrastructure.
- Processing and non-process infrastructure ($244 million): addition of a ball mill and upgrades to the magnetic circuit, flotation circuit, concentrate handling, tailings management, paste plant, power distribution, water and accommodation.
Key long-lead items, including the ball mill, were ordered as part of the early works programme, reducing schedule risk. The undiscounted payback from incremental cashflows is forecast at approximately 2.5 years from the end of construction.
What is a Final Investment Decision, and why does this one matter?
A Final Investment Decision is the point at which a company’s board formally commits capital to proceed with a project, moving from the study and planning phase into active construction. Before an FID, a project exists as optionality; after it, capital is allocated and a construction timeline is locked in.
For investors, FIDs matter because they convert potential into scheduled cash flow. They signal board-level conviction in both the economics and the execution plan, and they establish a defined timeline against which progress can be measured.
For Liontown specifically, this FID converts expansion optionality that was deliberately engineered into Kathleen Valley’s original plant design into a funded, scheduled project. The process plant was built from day one with a design capacity intended to accommodate scale-up to 4.2 Mtpa, meaning the expansion is characterised as “debottlenecking” an existing facility rather than building new capacity from scratch. Ottaviano described it as having “one of the lowest capital costs per tonne among recent brownfield lithium projects” and noted the operation “was built for this expansion from day one.”
That capital efficiency is a meaningful distinction. Brownfield expansions that utilise latent capacity in existing infrastructure typically carry lower execution risk and faster paths to first production than greenfield builds, and the approximately 2.5-year payback period from end of construction reflects that dynamic.

Mining scope, funding strategy, and what comes next
Accelerating Kathleen’s Corner Underground
The expanded mine plan is built on a two-ore-body strategy, with the Mount Mann Underground and Kathleen’s Corner Underground (formerly named North West Flats) each intended to operate independently, with their own infrastructure and multiple access points designed for operational flexibility.
Under the previous November 2024 mine plan, development of Kathleen’s Corner Underground had been deferred until FY31 to adapt to the low-price lithium environment. As a direct result of the FID, that development has now been accelerated to complement the Mount Mann Underground. An optimised mine design, including access to the Kathleen’s Corner Underground via the existing Open Pit, is expected to reduce underground development by approximately 45,000m compared to the previous design. Under the updated mine plan, ore mining rates are expected to increase progressively from FY27, reaching a sustained rate of approximately 4.1 Mtpa by the end of FY29.
Self-funded from balance sheet and operating cash flow
Liontown intends to fund the expansion through existing cash (reported at $561 million at the end of June 2026) and operating cash flow generated by Kathleen Valley, based on consensus pricing forecasts. The company has noted it retains flexibility to re-assess scope, defer, or stop activities if market conditions change during the project’s lifetime.
Expansion tonnes remain uncommitted, which the company says provides flexibility to consider spot sales, customer pre-payments, or new offtake contracts priced with reference to a spodumene index. Liontown noted it continues to receive regular inbound interest from potential new customers.
FY27 guidance update
FY27 production and unit operating cost guidance are unchanged. The only revision is to total capital expenditure, which has been updated to incorporate expansion capital approved at FID.
- Concentrate production: 390,000–440,000 dmt (unchanged)
- Unit operating cost: $1,050–$1,250/dmt sold FOB (unchanged)
- Total capital expenditure: updated to $435–$495 million (previously $320–$370 million), reflecting $175–$195 million of expansion capital now scheduled in FY27 (inclusive of the $60–70 million of expansion expenditure previously announced)
The expansion is also expected to create an estimated 210 FTE roles during construction, plus a further 185 ongoing FTE roles at Kathleen Valley once the expansion is complete, across Liontown and its contractor partners.
