The two current areas of focus are: • Creation of an ionic adsorption clay rare earth project in northern Tasmania. • Establishment of a plant to produce hydrogen fluoride and aluminium fluoride from recycled industrial waste, to replace imports (ALCORE). There is also a legacy business: • Mining and enhancing bauxite resources for cement, aluminium and fertiliser production. ABx endorses best practices on agricultural land, strives to leave land and environment better than we find it. We only operate where welcomed. ASX Announcement 26 May 2026 ASX: ABX ASX Release 26 May 2026 page 2 CHAIR’S ADDRESS Dear fellow shareholders, I would like to thank you for your continued support for ABx Group throughout 2025. It has been a transformational year for the Company, with significant progress achieved across our three priority projects; rare earths, ALCORE fluorine chemicals technology and bauxite. Importantly, these all advanced materially during the year and continue to position ABx as a uniquely diversified Australian critical minerals and industrial technology company. At our Deep Leads rare earths project in northern Tasmania, ABx achieved a major milestone with the successful production of our maiden mixed rare earth carbonate, or MREC, product. This was a particularly important achievement because it demonstrated not only our ability to extract rare earths from the Deep Leads resource, but also the exceptional quality of the product itself. Our MREC contains very high concentrations of dysprosium and terbium — two of the most valuable and strategically important heavy rare earth elements required for permanent magnets for electric vehicles, robotics and defence technologies. Importantly, our rare earths continue to demonstrate characteristics that distinguish ABx from many peers globally. The ionic clay mineralisation at Deep Leads allows extraction using benign reagents at ambient temperatures. This has the potential to translate into lower operating costs and higher product purity. Throughout the year, the Company also expanded its exploration footprint in Tasmania and continued exploration drilling programs that led to the identification of new rare earth discoveries southeast of Launceston. These discoveries further reinforce the prospectivity of ABx’s broader Tasmanian tenure position, much of which remains underexplored. At the same time, through our 83%-owned subsidiary ALCORE, we continued to make substantial progress as we advanced our innovative world-leading clean fluorine chemical technology. The ALCORE vision is both strategically and environmentally important, producing hydrogen fluoride and aluminium fluoride from an aluminium smelter by- product. During 2025, we secured a lease for the ALCORE Technology Centre, or ATC, adjacent to Rio Tinto’s Bell Bay aluminium smelter in Tasmania. We advanced development of the continuous pilot plant at the ATC. Major equipment orders were completed, detailed engineering progressed significantly and site infrastructure upgrades advanced throughout the year, with commissioning targeted to commence during Q3 2026. The continuous pilot plant represents a major step toward commercialising a technology capable of transforming a by-product into high-value industrial chemicals, while simultaneously supporting Australia’s sovereign manufacturing capability. Australia remains the world’s largest aluminium producing nation without domestic aluminium fluoride production. ALCORE therefore has the potential to solve an important supply chain challenge while also demonstrating Australian innovation on the global stage. ASX Release 26 May 2026 page 3 In bauxite, ABx also achieved significant strategic progress throughout the year, executing a partnership with Good Importing International, or GII, to advance the Sunrise Bauxite Project in Queensland, and support potential development pathways for the Taralga and Penrose projects in New South Wales. This partnership was an important milestone for ABx, bringing both funding and strong international marketing expertise to the projects. The Sunrise Project itself is particularly well positioned, with favourable logistics through Bundaberg Port and exposure to strengthening long-term demand for bauxite. ABx also continued progressing approvals at the DL130 bauxite project in Tasmania as we work toward commencing quarrying operations. Our work across these varied projects demonstrates the unique potential of ABx Group. Whether through rare earths critical to future technologies, ALCORE’s circular economy fluorine chemicals process, or our strategically located bauxite projects, ABx is positioned within industries of increasing global importance. Now is a pivotal time in the future of the Company. The foundations established throughout 2025 and vigorously progressed during 2026 have positioned ABx strongly for the years ahead. We remain focused on advancing these opportunities as fast as possible toward long-term value creation for shareholders. I sincerely thank our shareholders for their continued loyalty and support. I would also like to acknowledge the dedication and hard work of the Board, management team and all employees as we continue progressing this exciting next phase for ABx.
