• Appointment of Tim Netscher as Non-Executive Chair of Alluminous
• Continued commissioning of the pilot plant and analytical laboratory
• Strong inbound interest from potential customers and offtake partners
Impact Minerals Limited (ASX: IPT) is pleased to provide an update on the progress of Alluminous Pty Ltd, (50%-owned by Impact), which is advancing the development and commercialisation of the proprietary HiPurA® High Purity Alumina (HPA) technology platform (ASX Release April 26th 2025).
The HiPurA process is a modular and scalable solvent extraction (SX) method that uses a sulphatebased chemical feedstock to produce HPA, potentially providing substantial cost benefits over current producers (Figure 1).
Impact acquired a 50% stake in Alluminous to accelerate its entry into the HPA market and to explore the potential integration of the HiPurA process with the company’s Lake Hope project due to similarities in feedstock chemistry and aspects of the metallurgical flowsheets of the two processes (ASX Release April 26th 2025). Impact is pursuing this integration as part of its CRC-P research grant with Edith Cowan University and CPC Engineering (ASX Release October 28th 2024).
Since acquiring the HiPurA technology on 1st May 2025, Alluminous, under the guidance of CEO David Leavy, has made significant progress in both operational and commercial areas, particularly with the recent appointment of Mr Tim Netscher as Non-Executive Chair of Alluminous.
Mr Netscher is a highly experienced public company chair and director with decades of international mining and processing leadership. He is currently the Independent Non-Executive Chairman of Gold Road Resources (ASX: GOR), having joined the board in 2014 and been appointed Chair in 2016. Tim was instrumental in the current >$3 billion takeover of Gold Road by Goldfields Limited.
His executive career includes senior roles at Gindalbie Metals, Newmont Mining, Vale/PT Inco, BHP, and Impala Platinum, covering major capital project development, operations, sustainability, technology commercialization and business improvement across North and South America, Africa, Australia, and the Asia-Pacific. Mr Netscher is a Chartered Engineer, holds a BSc (Chemical Engineering), BCom, and MBA, and is a Fellow of IChemE and the AICD.
Mr Netscher said, “HiPurA® is a differentiated platform in a market that rewards quality, reliability and speed to qualification. The team’s integrated pilot-and-lab capability and modular process architecture provide a credible path from pilot samples to bankable offtake. I look forward to working with the board and management to execute disciplined, staged growth, deepen customer partnerships and deliver strong value-adding outcomes for all stakeholders.”
Impact’s Managing Director, Dr Mike Jones, said “Having Tim join the Board of Alluminous as Chair is a true validation of Alluminous’ business plan. He brings deep industry and governance experience and will play a critical role in guiding Alluminous through its transition from pilot operations to commercialisation.
Alluminous was established to do one thing very well—get qualified HPA into customers’ handsfaster. The combination of a pilot-scale plant, on-site high-purity analytical capability and a modular, compact flowsheet gives us that speed, while keeping capital light and scale-up de-risked. Those are the critical ingredients to win in the bespoke, specification-driven HPA markets.
“Alluminous’ roadmap is pragmatic and value-focused. First, pilot production for customer qualification; second, a U.S. demonstration plant to anchor North American offtake; and third, scale as orders accumulate. In parallel, we will look to back-engineer Lake Hope feed through HiPurA® using the existing micro-plant to preserve a natural-feedstock option alongside chemical routes— giving us true dual-feedstock flexibility and a faster path to revenue.”
