The ABx2 assets include the Taralga and Penrose Bauxite Projects in New South Wales (Figure 1). In September, ABx executed a series of agreements with GII that included an exclusive option for GII to invest $4.8m to acquire a 75% interest in ABx2, with the option fee payment due on 11 December 2025.1 Following payment of the $300,000 fee, GII now retains an exclusive option to 11 June 2026. The fee will be credited against the $4.8m investment if the option is exercised and completed. A portion of the $300,000 fee is anticipated to be deployed on Taralga project studies being conducted jointly by ABx and GII. ABx Group has fostered a strong collaborative relationship with GII, which has already invested $2.7 million to acquire 70% ownership of ABx3 Pty Ltd (ABx3), previously a wholly- owned subsidiary of ABx, which is developing the Sunrise Bauxite Project in Queensland.2 This forms part of an agreement under which GII will invest up to $5.4m to acquire up to a 75% interest in ABx3. Market analysts highlight that political, social, economic and logistical risks are multiplying as the global aluminium industry binds itself ever more tightly to Guinea. The price of Guinea bauxite spiked in in late 2024 and early 2025, due to severe supply disruptions.3 In August, Emirates Global Aluminium announced the termination of its Guinea bauxite operations following government expropriation. 1 ASX Announcement, 12 September 2025 2 ASX Announcement, 9 October 2025 3 ASX Announcement, 6 March 2025 ASX Announcement 9 December 2025 ASX: ABX ASX announcement 9 December 2025 page 2 Commenting on the extension, ABx Group Managing Director and CEO Mark Cooksey said: “We are pleased to continue to deepen our engagement with GII, who are already an exceptional partner for our Sunrise project in Queensland, bringing strong project development capability. The execution of the non-refundable extension fee for the NSW bauxite assets further signifies strong interest to deepen our collaboration. “Funds received are earmarked for NSW bauxite mine studies, ensuring that the Company capitalises on strong commodity market fundamentals as well as further strengthening our engagement with GII." Taralga and Penrose Bauxite Projects The ABx Taralga and Penrose bauxite deposits are located in New South Wales. The assets are held within ABx2, a wholly-owned subsidiary of ABx. The Taralga deposit consists of a JORC-compliant resource of 38 million tonnes4 of gibbsite- type metallurgical bauxite, located 200 km inland from Port Kembla. A 2012 pre-feasibility study (PFS) by independent engineers concluded that transport by road and rail was feasible, but subsequent delays in the expansion of Port Kembla outer harbour was the main obstacle to the project. Recent changes in Port Kembla logistics have been positive, and this project is now capable of delivering bauxite into the seaborne bauxite market and is therefore being reassessed. The Penrose discovery is a layer of refractory-grade bauxite in Penrose state pine forest, adjacent to the Hume Highway, 90 kilometres from Port Kembla5 . Refractory-grade bauxite is used for heat containment and abrasives and can sell for significantly higher prices than metallurgical grade bauxite.
