Impact Minerals Limited (ASX: IPT) is advancing a multi-pronged growth strategy centred on (1) the development of its proprietary HiPurA® High Purity Alumina (HPA) technology through 50%-owned Alluminous Pty Ltd and the Company’s 80% owned HPA Lake Hope Project in WA, and (2) Development of a multi-commodity industrial minerals hub at Lake Hope–Salmon Gums, incorporating HPA, sulphate of potash (SOP) fertiliser and hydrochloric acid (HCl); and (3) Large-scale exploration upside at its Broken Hill critical minerals portfolio.

This integrated strategy provides near-term commercialisation milestones, scalable downstream optionality, and district-scale exploration upside.

Impact has achieved key technical and commercial validation milestones through its Alluminous JV:

• First HPA shipment completed: ~15kg of HiPurA® HPA successfully produced and shipped to U.S.-based battery innovator C4V for testwork and qualification
• Marks first pilot-scale production and dispatch, achieved within ~9 months of investment
• Product now undergoing independent validation in C4V’s U.S. battery development facilities, supporting downstream qualification
• Strategic collaboration with C4V provides exposure to:
  • Advanced lithium-ion battery ecosystem
  • Independent performance validation
  • Potential OEM qualification pathways

• Perth pilot plant operating successfully in batch mode production
• Transition to continuous operation targeted near-term (key scale-up milestone)
• Early indications of higher-than-designed throughput potential, implying improved capital efficiency

• Appointment of experienced COO (Peter Barnes) to drive pilot-tocommercial scale-up pathway
• Appointment of Tim Netscher (Gold Road Chair -ASX.GOR) as Non-Executive Chair of Alluminous in 2025.
• Ongoing optimisation, scoping and execution planning underway

• Active U.S. engagement across battery, AI, semiconductor and advanced materials sectors
• Target end markets: lithium-ion batteries, semiconductors/AI infrastructure, optics, defence and photonics

Lake Hope HPA Project (80% owned)

• JORC Ore Reserve of 1.7 Mt @ 26% Al₂O₃ (450 kt contained alumina)
• June 2025 Pre-Feasibility Study (PFS) outlined 10,000 tpa production of 4N High Purity Alumina over a 33-year mine life
• Post-tax NPV of A$1.165 billion and IRR of 47%
• Initial capex A$259M; opex A$9,452/t (reduced to A$7,105/t with sulphate of potash by-product credit)
• Positioned in the lowest cost quartile globally; Definitive Feasibility Study (DFS) now underway

Lake Hope–Salmon Gums — Sulphate of Potash (SOP) Opportunity

• High-grade sulphate clay deposits identified as a complementary development to the HPA project
• Exploration Target of 3.8–4.3 million tonnes of sulphate clay defined
• Estimated 1.4–1.7 million tonnes of SOP equivalent contained within the target
• SOP production would also generate hydrochloric acid (HCl) as a co-product

Impact controls 100% of a large exploration portfolio at Broken Hill, NSW, one of the world’s most prolific mining districts.

• The projects are highly prospective for gold, silver copper, PGEs & nickel.
• Recent MT survey results have identified a deep crustal conductive corridor extending toward surface with associated near-surface targets, interpreted as a potential mineralising system architecture consistent with world-class deposits.
• This provides a strong geological framework for planned drilling in Q2 2026 and reinforces the Company’s exposure to large-scale discovery upside.
