PLS Group Limited has begun commissioning a Western Australian lithium-processing demonstration plant backed by up to A$38.1 million in Australian government funding, a move that pushes the miner beyond spodumene concentrate, the hard-rock lithium product sold to chemical converters. The company also has an offtake agreement — a forward sales deal — with China’s Ningbo Ronbay New Energy Technology Co. Ltd for lithium phosphate from the plant.
The timing matters because Australia mines much of the raw material used in batteries but does less of the higher-value processing at home. ARENA Chief Executive Darren Miller said Australia supplies “more than half” of the world’s spodumene but “refines only a small portion at home,” making the PLS trial a test of whether more battery-material work can stay onshore.

It also lands after a better quarter for PLS. The company reported record March-quarter production of 232.4 kilotonnes at Pilgangoora, revenue up 52% to A$567 million, and a closing cash balance of A$1.455 billion, helped by stronger lithium pricing and a US$100 million Canmax offtake prepayment.
The Mid-Stream Demonstration Plant, at PLS’s Pilgangoora operation in the Pilbara, is designed to process about 27,000 tonnes of spodumene concentrate a year and produce about 3,000 tonnes of lithium phosphate, a material used in lithium-ion batteries for electric vehicles and energy storage. The plant uses electric flash calcination, a high-heat processing step, and first product is expected in the September quarter of 2026.
ARENA said the project will trial Calix Limited’s electric-kiln technology, which could cut emissions from calcination by more than 80% when powered by renewable energy. The plant will draw power from Pilgangoora’s on-site energy system, which includes gas-fired generation, solar power and battery storage.
PLS Managing Director and Chief Executive Dale Henderson framed the project as a controlled step, not a full commercial shift. Henderson said the plant was meant to test whether “more value can be captured at the resource,” adding that it remained a “disciplined validation and optimisation phase.” PLS
PLS now owns and operates the plant outright after acquiring Calix’s ownership interest, though Calix remains a technology partner. The company said commissioning and ramp-up through fiscal 2027 will be staged, with operating rates rising as testing and optimisation progress.
The operating backdrop has improved. PLS said lithium recovery at Pilgangoora was stable at about 75%, March-quarter sales totalled 195.7 kilotonnes, and the average realised spodumene price rose 61% from the prior quarter to US$1,867 a tonne. Unit operating costs on an FOB basis, meaning before freight and some destination costs, fell 11% to A$520 a tonne.
Analysts focused on the margin beat. RBC Capital analyst Kaan Peker wrote that the result was a “clear beat” with “meaningful cost outperformance,” while Henderson told Reuters that demand was “deepening and broadening,” including from stationary batteries and electric trucks. Reuters
The broader lithium tape helped too. Market Index said lithium names were stronger on Monday, with PLS up 2.7%, Liontown Resources up 1.7% and IGO up 4.4%, as Chinese lithium carbonate futures rose. Broker views were split, however: CLSA kept PLS at outperform, RBC kept it at outperform, and Jarden cut the stock to underweight.
The peer comparison is not clean. IGO, which has exposure to the Greenbushes lithium mine, cut its fiscal 2026 Greenbushes production outlook to 1,375–1,425 kilotonnes from 1,500–1,650 kilotonnes and flagged higher unit costs, showing that the recent lithium price recovery has not removed operating pressure across the sector.
The main risk is that the plant remains a validation project. PLS said any development beyond the demonstration phase will depend on technology performance, product market development and market conditions; it also reported three recordable injuries in the March quarter and said safety performance remained below expectations.
PLS, formerly Pilbara Minerals, owns the Pilgangoora operation in Australia and the Colina lithium project in Brazil, and is linked further into the lithium chain through a POSCO joint venture in South Korea. The mid-stream trial is the next test of whether that portfolio can move closer to battery chemicals without taking on the cost and risk of a full refinery build-out.
