Impact Minerals (ASX:IPT) ships initial HiPurA® HPA to C4V as pilot plant advances toward continuous operation

Impact Minerals has marked a technical and commercial milestone in its high purity alumina strategy, with its 50% owned associate Alluminous Pty Ltd shipping approximately 15 kg of HiPurA® High Purity Alumina samples to U.S. battery materials innovator Charge CCCV LLC under the existing Technology Development Agreement.

The consignment represents the first significant quantities of HPA produced and dispatched from the Alluminous pilot plant in Perth, 9 months after Impact’s investment in the technology.

Highlights

• Approximately 15 kg of HiPurA® HPA shipped to C4V in the United States for initial testwork
• First significant quantities produced at the Alluminous pilot plant, 9 months after Impact’s investment
• Pilot plant operating successfully in batch mode, with continuous mode targeted next quarter
• Peter Barnes appointed Chief Operating Officer to oversee optimisation and scale up

The shipment advances Alluminous’s product qualification process, with the material undergoing formal testing within C4V’s laboratory and pilot-scale facilities.

The collaboration centres on testing, engineering and validation efforts designed to turn HiPurA® HPA into a material suitable for direct use in lithium-ion battery manufacturing, with C4V’s facilities expected to generate independent performance data to support product approval and further customer engagement.

C4V operates from the Centre of Excellence at Binghamton University in New York State, a recognised lithium-ion research hub, and is integrated within the broader U.S. battery technology ecosystem.

Recent meetings in New York between Alluminous Managing Director David Leavy and the C4V technical team aligned the scope and sequence of the testwork programme, reinforcing the structured pathway from pilot-scale production to qualification.

Operationally, the Perth pilot plant is producing HPA and precursor materials in batch mode in accordance with internal quality specifications.

The next key performance indicator is transition to continuous mode operation during the coming quarter, a shift intended to support sustained sample production and more robust qualification activities with C4V and potential customers.

Initial assessment indicates the existing facility may be capable of substantial increases in throughput compared with the original design, with further work under way to quantify this and the associated capital requirements.

Impact Minerals Managing Director Dr Mike Jones framed the shipment as a tangible step forward, stating

“This tangible milestone demonstrates execution capability and moves us closer to product qualification in technically demanding battery markets.”

Corporate capability has also been strengthened with the appointment of Peter Barnes as Chief Operating Officer.

A Chemical Engineer with an MBA from UWA and experience in scaling operations from pilot plant through feasibility and commercialisation, Barnes will oversee pilot plant optimisation, manage the scoping study process and plan project scale-up.

Beyond the technical programme, Alluminous has intensified market engagement in the United States, including meetings in New York, Washington DC and San Francisco, and attendance at SPIE Photonics West in January.

These activities are informing product development, qualification priorities and commercial planning across battery and other advanced end markets.

The immediate focus remains operational execution: optimise pilot plant performance, transition to continuous operation, assess throughput potential and integrate C4V’s performance feedback into product development.

In parallel, Impact will continue to develop the Lake Hope project and evaluate incorporation of natural feedstock with HiPurA® downstream processing.

For investors tracking downstream processing optionality within the battery materials value chain, the next phase hinges on independent validation data and the scalability metrics emerging from the Perth facility.
