The historic Bleiberg Mine reportedly produced approximately 5.5 million ounces of germanium prior to closure, ranking it among the largest global germanium producers and underscoring the district-scale significance of the project.ii o Apex (Utah, USA): 129 mining claims (~2,660 acres) surrounding the historic Apex Mine (world’s first primary Ge–Ga mine), with historic grades reported up to 0.7% Ge (7,000 g/t) and 2% Ga (20,000 g/t) and ~180,000 oz of silver produced.iii ASX Announcement Released 9 March 2026 2 • BM8's Multi-Year Germanium Strategy: BM8 is pursuing a comprehensive, long-term plan to identify, advance, and align germanium resources in Western jurisdictions, adhering to downstream processing and supply-chain standards. • Strategic supply-chain tailwinds: Amid rising export restrictions and geopolitical tensions affecting global germanium availability, BM8’s EU and US Ge portfolio provides unique exposure to a critical technology material increasingly important to advanced computing and AI, data centres and communications infrastructure. Battery Age Minerals Ltd (ASX: BM8; “Battery Age” or “the Company”) is pleased to announce that it is progressing its strategy to build exposure to a secure, Western-aligned supply of germanium, a critical material used across advanced technology supply chains. As part of this strategy, the Company is advancing two complementary initiatives designed to strengthen the Company’s end-market readiness as it progresses its germanium projects in Austria and the USA. First, BM8 has secured an evaluation licence with NTUitive (Nanyang Technological University’s commercialisation entity) to evaluate six germanium-related inventions and associated proprietary materials. This evaluation is intended to strengthen BM8’s downstream specification and qualification know-how, an important capability in qualification-driven markets where purity, consistency and traceability can influence pricing, market access and long-term supply contracting. Second, following on from the Company’s announcement on 31 October 2025, the Company continues to progress a sustainable processing pathways workstream assessing approaches aimed at reducing chemical intensity and energy input compared with conventional methods, supporting optionality for cleaner, safer and potentially more cost-effective processing outcomes over time. This follows completion of the Company’s maiden drill program at the Bleiberg Zinc-Germanium Project in Austria, with assays currently pending. These initiatives build on BM8’s sustained exploration focus on germanium over recent years. Since 2022, the Company has actively assembled and advanced a portfolio of germanium-prospective assets in Austria and the United States, undertaken geological and drilling programs, and engaged with downstream and policy stakeholders to support the development of secure, Western-aligned germanium supply pathways. STRATEGIC RATIONALE – WHY THIS MATTERS FOR BM8 Germanium is a strategically important material used across high-value and technologically critical applications, including fibre-optic networks, infrared optics and imaging, specialised electronics and advanced sensing systems. These end markets are typically specification-driven, with product purity, impurity thresholds and consistency influencing pricing, qualification and market access. Global supply remains relatively concentrated and is increasingly influenced by geopolitics and export controls, reinforcing the importance of secure, Western-aligned sources and pathways. As demand for advanced computing, communications infrastructure and sensing technologies grows, the role of germanium as an enabling material across multiple technology stacks is expected to remain strategically significant. Against this backdrop, BM8 is evaluating germanium-linked technologies to: • clarify downstream product specifications and qualification requirements; • inform product positioning and potential future pathway decisions; and ASX Announcement Released 9 March 2026 3 • support strategic engagement with potential partners through improved technical alignment. INTEGRATED APPROACH – FROM RESOURCE TO SPECIFICATION Higher-value germanium markets are qualification-driven: small variations in purity and impurity control can materially impact device performance, yield and reliability. BM8’s approach is therefore to build capability across two linked areas: • Downstream specification context: to better understand the product parameters and qualification requirements that matter to end users; and • Upstream processing optionality (sustainable pathways): to assess pathways that may reduce chemical intensity and energy input while supporting improved consistency and responsible sourcing outcomes. Together, these initiatives are intended to support BM8’s ability to engage end customers and strategic partners with a clearer, customer-led value proposition as BM8 progresses its core germanium projects. This approach is intended to complement BM8’s ongoing exploration programs by ensuring that resource development decisions are informed by long-term end-market and supply-chain considerations. Nanyang Technological University, Singapore (NTU Singapore) A research-intensive public university, Nanyang Technological University, Singapore (NTU Singapore) is home to world-renowned autonomous institutes – the National Institute of Education, S Rajaratnam School of International Studies and Singapore Centre for Environmental Life Sciences Engineering – and various leading research centres such as the Earth Observatory of Singapore, Nanyang Environment & Water Research Institute and Energy Research Institute @ NTU (ERI@N). Under the NTU Smart Campus vision, the University harnesses the power of digital technology and tech-enabled solutions to support better learning and living experiences, the discovery of new knowledge, and the sustainability of resources. NTUitive Pte Ltd, is the innovation and enterprise company - and a wholly-owned subsidiary – of NTU.

BM8 will use the evaluation to refine its understanding of downstream specification requirements and potential collaboration pathways relevant to higher-value germanium applications, as the Company progresses its core projects at Bleiberg–Hochobir (Austria) and Apex (Utah, USA). EVALUATION PROGRAM – SCOPE The evaluation licence provides a licence to evaluate six inventions in germanium (Ge) based optoelectronics and integration platforms within the field of advanced semiconductor and optoelectronics device fabrication, including: 1) Material Property Testing The evaluated patents disclose material-level approaches for integrating germanium related material on silicon, including epitaxial growth methods, graded or step-graded buffer designs, strain management techniques, and wafer-scale uniformity considerations. The technical disclosures address lattice mismatch, thermal stress, defect formation, and impurity and contamination control during growth and processing. ASX Announcement Released 9 March 2026 4 BM8 is reviewing these disclosures to better understand how material quality, defect density and impurity thresholds influence downstream performance expectations and material specifications. 2) Device-Level Architectures and Performance Sensitivity At the device level, the patents describe silicon-compatible optoelectronic architectures that utilise germanium based active layers, including resonant-cavity and strain-engineered structures intended to enhance optical absorption, sensitivity and wavelength-specific response. The disclosures highlight the dependence of device performance and yield on material quality, composition, interface control and process consistency. BM8 is assessing these device concepts to understand how downstream performance and qualification requirements translate into tighter material and process control. 3) Platform Integration and System-Level Considerations The evaluated patents also include platform-level concepts addressing integration of germanium-based materials and devices into broader photonic or sensing systems. These disclosures cover layer transfer, insulation schemes, stressor structures and waveguiding architectures designed to support system-level functionality within silicon-compatible processes. BM8 is using these system-level disclosures to understand how application-specific integration and qualification considerations can shape end-user requirements and collaboration pathways. 4) Overall Technical Evaluation Collectively, the patent disclosures across material, device and system domains provide BM8 with a structured technical reference for assessing advanced germanium technologies. This evaluation enables BM8’s ongoing efforts to refine product positioning and engagement strategies in specification-driven germanium markets. Figure 1: Abstract Graphic Representation of Evaluation Programme ASX Announcement Released 9 March 2026 5 SUSTAINABLE PROCESSING PATHWAYS (EVALUATION STAGE) BM8 is assessing environmentally sustainable germanium processing concepts aimed at reducing the hazardous reagent burden, lowering energy intensity and improving process safety versus conventional approaches. Concepts under review include: • Mechanochemical activation approaches (e.g., ball milling-based activation to support extraction under milder conditions); and • Low-acid / organic-acid leaching concepts (using milder organic acids to selectively dissolve germanium and reduce hazardous waste streams). This workstream is being assessed to support optionality for cleaner processing pathways and to align with increasing customer and regulatory emphasis on responsible sourcing and lower-impact production. This is an evaluation/scoping program and does not represent a commitment to develop a specific processing facility or downstream manufacturing capability. Figure 2: Impact of Pathways for Germanium Extraction ASX Announcement Released 9 March 2026 6 BM8’s GERMANIUM LEADERSHIP BM8’s germanium portfolio spans two historically significant districts: • Bleiberg–Hochobir (Austria): BM8’s landholding covers approximately 330 km² across two historical mining districts known for extensive lead-zinc production and associated germanium mineralisation, with historic concentrate grades reported up to 1,500 g/t Ge. • Apex Project (Utah, USA): BM8 has staked 129 mining claims (~2,660 acres) surrounding the historic Apex Mine in the Beaver Dam Mountains. The Apex Mine (also known as the Dixie Mine) is recognised as the world’s first primary germanium–gallium mine, with historic reporting of grades up to 0.7% Ge (7,000 g/t) and 2% Ga (20,000 g/t), alongside ~180,000 oz of silver produced. As part of its ongoing long-term germanium strategy, BM8 intends to continue advancing exploration activities across its portfolio. At Bleiberg, the Company is planning further staged exploration programs during 2026, building on the Phase 1 drilling completed in H2 2025 and the multiple priority targets identified across the historic mining corridor. At the Apex Project in Utah, initial work programs are expected to focus on detailed geological mapping, surface prospecting and target refinement to support future exploration planning. As BM8 advances work programs across Bleiberg–Hochobir and Apex, the Company’s focus remains on building a secure, Western-aligned germanium supply chain. The NTU evaluation strengthens BM8’s downstream specification and qualification know-how, while the sustainable processing pathways workstream supports optionality for cleaner and more efficient production outcomes. In combination, these initiatives are intended to improve BM8’s “mine-to-market” readiness and support engagement with end customers and strategic partners seeking secure, compliant supply. BM8 will update the market on material outcomes as the evaluation progresses.
