Announcement PDF ASX Code: IPT DECEMBER 12th, 2025 CORPORATE RELEASE IMPACT MINERALS LTD APPOINTS SCOTT PHEGAN AS EXECUTIVE DIRECTOR TO SUPPORT NEXT PHASE OF HPA GROWTH Impact Minerals Limited (ASX: IPT) is pleased to announce the appointment of Mr Scott Phegan as an Executive Director, effective immediately. Scott is a highly experienced chemical engineer with over 30 years of global operational, technical, and project development expertise in the bauxite, alumina, and specialty materials industries. Scott spent a significant part of his career with Alcoa, where he held senior leadership and operational roles across Australia, the United States and Brazil. He was directly involved in major multibillion-dollar refinery expansions, operational turnarounds and technology upgrades, giving him an exceptional understanding of the design, commissioning and optimisation of complex chemical processing facilities. Since 2019, Scott has focused on developing new hydrometallurgical processes for high-purity materials, including high purity alumina (HPA) and rare earth extraction. He has consulted widely across the sector and serves on the board of Canyon Resources, which is developing one of the largest undeveloped bauxite deposits globally in Cameroon. Scott also sits on the board of Alluminous Pty Ltd, along with Impact’s Managing Director, Dr Mike Jones, representing Impact’s 50% interest as the company advances the HiPurA® HPA processing technology and commissions the pilot plant. His close involvement in both the Lake Hope PFS and the downstream HiPurA integration strategy positions him uniquely to help guide Impact through its transition from developer to future producer. Dr Jones said, “Scott has been crucial to our HPA strategy for some time, using his extensive operational experience to help design the commercial flowsheet for the Lake Hope Pre-Feasibility Study. His background at Alcoa—where he led major refinery expansions and optimised large-scale continuous chemical operations—has been invaluable in creating a technically robust and scalable development pathway for Impact. As we now enter the next phase of growth, with pilot-scale production, the integration of the HiPurA® technology and preparation for a Definitive Feasibility Study, Scott’s appointment to the Board strengthens our operational capability at exactly the right moment. His leadership, technical insight and global industry network will be instrumental in driving Impact towards becoming a fully integrated, high-purity alumina producer”. We are delighted to formally welcome Scott to the Board.” ASX:IPT | ABN 52 119 062 261 2 Mr Phegan said, “I am genuinely excited to step into the role of Executive Director at such a pivotal moment for Impact. Over the past year, working with the team on Lake Hope and the HiPurA® technology has shown me just how differentiated our position is in the emerging HPA sector. The combination of a uniquely simple natural feedstock and a modular downstream processing pathway presents an opportunity that is rare in this industry. “My background has always been rooted in building and operating large-scale alumina assets, and I see enormous potential to bring that experience to bear as Impact moves from study phase into execution. The team has built real momentum, and I’m looking forward to helping deliver the next stages of development, strengthen our operational capability, and progress Impact toward becoming a meaningful global producer of high-purity alumina.” Impact looks forward to continuing working with Scott as it continues on its journey to HPA production.
