Impact Minerals New Technology Advances HPA Commercialisation with Alluminous

Alluminous Appoints Mining Veteran Tim Netscher as Chair, Fast-Tracks HPA Commercialization

Impact Minerals (ASX: IPT) has announced significant progress at its 50%-owned Alluminous Pty Ltd, with the appointment of experienced mining executive Tim Netscher as Non-Executive Chair and advances in both pilot plant operations and commercial engagement for its proprietary HiPurA® High Purity Alumina technology.

High-Profile Leadership Appointment Signals Commercial Intent

In a significant governance boost, Alluminous has appointed Tim Netscher as Non-Executive Chair, bringing decades of international mining and processing leadership to the company. Netscher currently serves as Independent Non-Executive Chairman of Gold Road Resources (ASX: GOR) and has played an instrumental role in the current $3 billion+ takeover of Gold Road by Goldfields Limited.

His executive experience includes senior positions at Gindalbie Metals, Newmont Mining, Vale/PT Inco, BHP, and Impala Platinum, with expertise spanning major capital project development, operations, sustainability, technology commercialization and business improvement across multiple continents.

"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." – Tim Netscher, Non-Executive Chair, Alluminous

HiPurA® Technology: A Potential Game-Changer in HPA Production

Alluminous' proprietary HiPurA® process represents a novel approach to HPA production, utilizing a modular and scalable solvent extraction (SX) method with a sulphate-based chemical feedstock. This approach potentially offers substantial cost benefits compared to existing HPA production methods.

The technology's key advantages include:

• Modular design enabling replication in a low-capex fashion
• Integrated pilot plant and analytical laboratory for rapid sample production and testing
• Ability to produce multiple high-purity alumina products beyond standard HPA
• Potential compatibility with Impact's Lake Hope project chemistry

Operational Progress Accelerates Toward Customer Qualification

Alluminous has made significant strides at its Perth-based pilot facility, including:

• Completed installation of safety, governance, finance and administration systems
• Advanced commissioning of the HiPurA® pilot plant, with electrical circuits installed and SX circuits completed
• Initiated batch processing of feedstock through various components of the process
• Recruited additional senior technical and project personnel with expertise in chemical engineering, project delivery, and advanced materials R&D
• Commenced commissioning of the high-purity laboratory with an analytical chemist hired to operate it

The pilot plant and laboratory combination provides Alluminous with a critical advantage: the ability to rapidly produce and analyze HPA samples for potential customers, dramatically shortening the qualification timeline.

Market Expansion Beyond Traditional HPA Applications

Alluminous is exploring production of multiple high-value alumina products to address various high-tech markets:

Customer engagement programs are already underway, including discussions on battery-grade HPA evaluation and solid-state/ceramic applications. The company has also initiated conversations with marketing agents in Europe and North America to target specific market segments.

Understanding High Purity Alumina (HPA): A Critical Material in Energy Transition

High Purity Alumina (HPA) is a premium non-metallurgical alumina product characterized by its purity level, typically 99.99% (4N) aluminum oxide or higher. While traditional alumina is used primarily for aluminum metal production, HPA serves specialized high-tech applications.

The material's exceptional properties make it invaluable for several growing markets:

• LED lighting: As a substrate for LED chips, providing thermal stability and electrical insulation
• Lithium-ion batteries: As a coating on battery separator sheets, improving safety and extending battery life
• Semiconductor substrates: For electronics requiring high thermal conductivity
• Optical applications: For specialized lenses and display screens
• Biomedical implants: Due to its biocompatibility and wear resistance

The global HPA market is projected to grow significantly as these applications expand, particularly with the accelerating electric vehicle and energy storage revolution requiring ever-increasing volumes of high-performance batteries.

Disciplined Commercialization Roadmap with Multiple Value Inflection Points

Impact's Managing Director, Dr. Mike Jones, outlined Alluminous' three-phase commercialization strategy:

1. Pilot production for customer qualification
2. U.S. demonstration plant to anchor North American offtake
3. Scale-up as orders accumulate

This staged approach allows for capital-efficient growth while reducing technical and market risks. In parallel, Alluminous will explore integrating Impact Minerals new technology with the HiPurA® process, potentially creating a dual-feedstock strategy that combines chemical and natural feedstock options.

"Alluminous was established to do one thing very well—get qualified HPA into customers' hands faster. 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." – Dr. Mike Jones, Managing Director, Impact Minerals

Immediate Work Program Focused on Customer Qualification and Commercialization

Alluminous has outlined six key focus areas for its immediate work program:

1. Continued improvements and commissioning of the pilot plant
2. Commencement of pilot sample campaigns for targeted customers across multiple applications
3. Validation of North American demonstration plant scope, site options and permitting path
4. Advancement of Lake Hope back-engineering to define blends/specs and preserve dual-feedstock flexibility
5. Formalization of customer engagement frameworks to shorten time from sample to purchase order
6. Continuation of IP consolidation and process optimization
