PLS Approves A$1.9 Billion Pilgangoora Expansion to Reach 2 Million Tonnes
Agrilinkage Companies & Investment | 18 October 2026
PLS Group has approved the largest investment in its history: a A$1.9 billion expansion designed to lift annual spodumene concentrate output at its wholly owned Pilgangoora operation in Western Australia to about 2 million tonnes. The decision moves P2000 from feasibility study to committed construction, with first production targeted for the September quarter of 2029 and an approximately six-month ramp-up.
The company’s 16 October 2026 ASX presentation sets a 10-year average production case of 1.97 million tonnes a year at 5.2% lithium oxide concentrate. A companion PLS project announcement says early site preparation is under way and construction is expected to take roughly two and a half years.
A processing project, not simply a bigger mine
P2000 is significant because its core proposition is to recover value from the boundary between ore and waste. PLS plans to build a third major processing facility, named Jimmagunya, alongside the existing Pilgan plant. The design pairs a 9.0-million-tonne-a-year dry plant with a 6.3-million-tonne-a-year wet plant and targets about 70% lithium recovery.
The feasibility study says ore sorting and flotation should allow approximately 67 million tonnes of mineralised contact material previously treated as uneconomic waste to be processed as ore. If the flowsheet performs as modelled, the gain is larger than the added plant capacity alone: lower waste movement and a reduced strip ratio can change mine scheduling, equipment use and unit costs across the operation. That is the operational thesis investors should watch during commissioning.
The resource case has also expanded. PLS reported an updated Pilgangoora Ore Reserve of 249.2 million tonnes at 1.24% lithium oxide, a 23% increase in reserve tonnes and a 31% increase in contained lithium. The total includes a first underground reserve of 46.5 million tonnes at 1.50% lithium oxide. Underground development is not part of the P2000 approval and would require a separate investment decision.
The financial case depends on a long-term lithium price
PLS estimates incremental post-tax net present value of A$2.7 billion at an 8% discount rate and a post-tax internal rate of return of 29.5%. Those are company-modelled outcomes, not guaranteed returns. They assume a long-term spodumene price of US$1,620 a tonne on a 6% lithium oxide, cost-and-freight China basis, together with the study’s recovery, cost, construction and ramp-up assumptions.
Agrilinkage calculates that the A$1.9 billion project cost equals about 70% of the company’s modelled A$2.7 billion NPV, or an NPV-to-capital ratio of roughly 1.42. That is a useful shorthand for the base case, but the sensitivity chart is more important: PLS shows the NPV falling to about A$0.7 billion at a US$1,000-a-tonne long-term price and rising to A$7.8 billion at US$3,000. The approved plant therefore increases exposure to a lithium-cycle recovery as well as exposure to a weaker price environment.
Measure | PLS case | Decision-use |
P2000 capital | A$1.9 billion | A$500m FY27, A$900m FY28, A$500m FY29 |
Output target | 1.97 Mtpa 10-year average | About 2 Mtpa of SC5.2 concentrate |
First production | September quarter 2029 | About six months of ramp-up follows |
Post-tax economics | A$2.7bn NPV; 29.5% IRR | Company model at US$1,620/t SC6 |
Modeled unit cost | A$620/t FOB | Real FY31-FY40 average |
The study’s A$620-a-tonne free-on-board operating-cost estimate is a real-dollar average for fiscal 2031 through 2040. It should not be read as a current spot cost or a fixed future outcome. Mining depth, energy, labour, reagent prices, recoveries and logistics can all move the realised number.
A second infrastructure programme raises the disclosed commitment
Alongside P2000, PLS announced A$600 million to A$650 million of Pilgangoora infrastructure spending. At the top of that range, the two disclosed programmes total A$2.55 billion. The infrastructure package is broader than the new processing plant and is intended to benefit the existing operation as well as P2000; PLS says attributable infrastructure is included in its P2000 valuation, so the figures should not be added to the NPV calculation as though they were completely separate.
The programme includes sealing and upgrading about 24 kilometres of Wodgina Road East, a new 1,200-bed accommodation village and a purpose-built mine-services facility. The road work is intended to accommodate ultra-quad road trains and reduce concentrate-haulage movements by around 35%. Western Australia has committed an initial A$11 million to the Great Northern Highway intersection, while any further public contribution for the seven-kilometre public-road section remains subject to government budget processes.
PLS expects the village to begin entering service progressively from late 2027 and the road work to finish by the end of 2028. These dates matter because infrastructure readiness must precede the higher material and workforce flows expected as Jimmagunya approaches commissioning.
Scale changes the company’s risk profile
PLS produced 879,500 tonnes in fiscal 2026, up 17% from the prior year, and reported A$1.93 billion of revenue and A$1.14 billion of underlying EBITDA, according to its FY26 results. Comparing that actual output with the 1.97-million-tonne P2000 study average suggests a future operating scale about 2.24 times the FY26 level. This is not a like-for-like capacity comparison—FY26 output includes the operating conditions of that year—but it shows the magnitude of the transition management is attempting.
The construction case also has regional consequences. PLS expects more than 1,000 construction jobs and about 500 continuing operating roles, plus procurement opportunities in the Pilbara and across Western Australia. The company says dry-stack tailings, water recovery and related design choices could reduce water intensity by up to roughly 40%. These are forward-looking claims that need to be tested against operating data once the plant is running.
What to watch before 2029
Capital discipline: whether the A$500m/A$900m/A$500m annual P2000 spending profile remains intact through peak construction.
Processing performance: whether ore sorting and flotation deliver the planned recoveries from contact material at commercial scale.
Lithium pricing: how long-term contract and spot indicators compare with the study’s US$1,620/t SC6 base assumption.
Infrastructure sequencing: completion of the road, village and services facility before Jimmagunya’s ramp-up.
Approvals and stakeholder delivery: environmental, heritage and Traditional Owner engagement as construction advances.
P2000 is therefore more than a volume expansion. It is a bet that better separation technology can convert marginal material into ore, that a larger reserve can support decades of output and that scale can lower the cost position enough to withstand lithium-price cycles. The final investment decision makes that thesis measurable: capital spending, recovery, water intensity, unit cost and ramp-up performance now have dated milestones against which the project can be judged.
