Announcement PDF ASX Announcement Battery Age Minerals Ltd ASX: BM8 ACN 085 905 997 batteryageminerals.au T: +61 (8) 9465 1041 E: info@batteryage.au Level 50, 108 St Georges Terrace Perth, WA 6000 PO Box 7310, Cloisters Square Po, WA 6850 1 Released 25 June 2026 BM8 Advances Integrated Germanium Strategy BM8 completes licence over NTUitive’s portfolio of germanium-related technologies Battery Age Minerals Ltd (ASX:BM8, “Battery Age” or “the Company”) is pleased to announce completion of the Exclusive Patent and Know-How Licence Agreement with NTUitive Pte Ltd (“NTUitive”), the innovation and enterprise company of Nanyang Technological University, Singapore ("NTU Singapore"). Execution of the commercial licence follows the Company’s 9 March 2026 announcement in which Battery Age held an option to enter the licence under an evaluation licence arrangement with NTU Singapore. Battery Age CEO, Sebastian Kneer, commented: “Completion of this licence marks another important step in BM8’s strategy to build a Western-aligned germanium supply chain with credible end-market relevance. Combined with our germanium projects at Bleiberg–Hochobir and Apex and our sustainable processing pathways workstream, this licence strengthens BM8’s engagement with end customers and strategic partners through a clearer, specification- led value proposition.“ 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. Bleiberg is recognised as one of the world’s most significant historic zinc–germanium districts, with the historic Bleiberg Mine reportedly having produced approximately 5.5 million ounces of germanium prior to closure1 , historically ranking it among the largest global germanium producers and underscoring the district- scale significance of the project. • Apex Project (Utah, USA): BM8’s landholding covers 186 mining claims (~3,728 acres) surrounding the historic Apex Mine in the Beaver Dam Mountains, UTAH, USA. Apex is recognised as the world’s first primary germanium–gallium mine and was historically noted for high-grade germanium and gallium mineralisation2 . As BM8 advances work programs across Bleiberg and Apex, the Company’s focus remains on contributing to a secure, Western-aligned germanium supply chain whilst advancing an integrated germanium strategy. The exclusive worldwide commercial licence further strengthens downstream specification and qualification position, 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. ASX Announcement Released 25 June 2026 2 BM8 will pursue further research to support the Company’s broad strategy of understanding downstream germanium-based semiconductor and optoelectronic market requirements. 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.
