Calix has received the last $5.7 million installment from PLS under their Mid-Stream Project restructure, with commissioning of the demonstration plant progressing on schedule and first lithium phosphate production expected soon.
- Second and final $5.7m payment received from PLS
- Mid-Stream Demonstration Plant officially opened in June
- Electric calciner completed successful full heat cycles
- First spodumene calcination and lithium phosphate production expected Q3 2026
- Project commissioning remains on track
Final Payment Marks Capital Release in Mid-Stream Project
Calix Limited (ASX:CXL) has secured the second and final A$5.7 million payment from PLS Group Limited (ASX:PLS), completing the financial restructure agreed in April 2026 for their Mid-Stream lithium project. This payment effectively releases Calix’s invested capital tied up in the project, signalling a shift towards a capital-light licensing and royalty model that reduces upfront expenditure and risk.
Demonstration Plant Commissioning Advances as Planned
The Mid-Stream Demonstration Plant, located at PLS’s Pilgangoora Operation in Western Australia, was officially opened on 5 June 2026 by Western Australia Premier Roger Cook and ARENA Chair Justin Punch. Commissioning is progressing on schedule, with Calix’s electric calciner successfully completing full heat cycles that confirm its power draw and heating range meet design specifications. This milestone validates the core technology underpinning the project’s lithium processing ambitions.
First Production Expected in September Quarter
Calix anticipates the first spodumene calcination and lithium phosphate production in the September quarter of 2026, a critical operational milestone that will demonstrate the plant’s ability to convert raw material into battery-grade lithium products. While this timing is forward-looking and subject to commissioning outcomes, it represents a tangible step towards commercial-scale production and potential royalty revenue streams.
Calix’s Technology and Strategic Positioning
Calix’s patented electric calciner technology is designed to enable flexible energy use and efficient resource processing, aiming to reduce emissions in mineral processing industries. The Mid-Stream Project exemplifies Calix’s broader strategy to future-proof essential materials production through decarbonisation and electrification. This approach complements recent developments in Calix’s industrial decarbonisation portfolio, including partnerships in cement and iron sectors.
Bottom Line?
The final payment from PLS and successful commissioning milestones de-risk Calix’s Mid-Stream Project, but investors should watch closely for the transition from demonstration to consistent production and royalty generation.
Questions in the middle?
- Will the Mid-Stream plant meet its lithium phosphate production target in Q3 2026?
- How quickly can Calix scale royalty income from this project following commissioning?
- What further capital-light partnerships might Calix pursue to leverage its electric calciner technology?
