Impact Minerals Advances Scalable HPA Project on ASX 200 with Modular Model

Highlights

• Impact Minerals (ASX:IPT) progresses Lake Hope Project with a completed Prefeasibility Study.

• Project positioned for low-cost, scalable High-Purity Alumina (HPA) production in Western Australia.

• Integration of HiPurA technology supports flexible, modular downstream development.

Impact Minerals Limited (ASX:IPT), listed on the ASX 200, has progressed its Lake Hope High-Purity Alumina (HPA) Project in Western Australia, with the completion of a Prefeasibility Study (PFS) outlining the path toward a scalable and capital-efficient operation. The company, which operates within the materials sector, is targeting the upstream production of HPA from its proprietary feedstock resource, backed by a vertically integrated development approach.

Prefeasibility Study Reveals Strong Project Metrics

The Lake Hope Project’s PFS outlines plans for consistent annual HPA output across several decades, supported by a straightforward and efficient flowsheet. Designed to meet emerging demand in a rapidly expanding HPA market, the study presents life-of-mine operational cost figures that place the project among the lower quartile globally, reinforcing its viability for long-term development.

The economic model incorporates a significant post-tax cashflow projection and outlines a substantial net present value, highlighting the financial scale of the project over its estimated life. The capital outlay is expected to remain manageable, in line with the project’s low-cost positioning.

Strategic Environmental and Process Advantages

Impact Minerals emphasizes Lake Hope’s naturally occurring feedstock and simplified processing route, which avoids reliance on complex reagents. This supports a reduced carbon footprint and positions the project within global sustainability benchmarks for HPA production. The ability to produce high-purity output with minimal environmental burden is expected to enhance market competitiveness.

The flowsheet’s simplicity and efficiency are also expected to contribute to faster development timelines, reduced commissioning risk, and greater process stability. According to the company, these factors collectively strengthen its path toward commercial production readiness.

Engineering and Pilot Scale Initiatives Underway

Following the PFS, the company has commenced detailed engineering activities aimed at transitioning the project into its next phase. This includes a Definitive Feasibility Study (DFS) and the construction of a pilot plant capable of generating commercial-grade HPA product samples. These samples are intended for qualification by prospective offtake partners, enabling the company to initiate strategic discussions.

The development of the pilot plant is also linked to a collaborative research effort with Edith Cowan University and CPC Engineering. This co-funded initiative is focused on refining the process design and is expected to produce enhancements to the existing flowsheet.

Modular Downstream Development with HiPurA

Impact Minerals recently secured a stake in Alluminous and its proprietary HiPurA HPA technology. This downstream integration is structured to align with Lake Hope’s upstream feedstock, creating a fully controlled supply chain from resource to finished product. The HiPurA process is modular, allowing Impact to adjust production volumes in response to customer demand without incurring excessive capital requirements.

The company notes that this model offers flexibility for scaling and reduces execution risk during the early revenue phases. The combined strategy of upstream security and modular downstream capability enables a vertically integrated production profile.

Project Location and Resource Details

Lake Hope spans a large area across salt lake systems in southern Western Australia, stretching between Hyden and Norseman. The project’s maiden ore reserve includes a combination of proved and probable resources with high-grade aluminium oxide content.

The company plans to leverage this geological foundation as a long-life feedstock source to support its integrated production strategy.

Industry Engagement

Impact Minerals is scheduled to participate in the upcoming Noosa Mining Investor Conference, held at Peppers Noosa Resort. The event is a significant platform for ASX-listed mining and resource companies to engage with institutional and retail stakeholders.
