Announcement PDF 11 March 2024 ASX ANNOUNCEMENT PHASE 4 KANGAROO HILLS DRILLING COMMENCED Highlights  Reverse Circulation (RC) drilling of key northern targets at Kangaroo Hills Lithium Project (KHLP) commenced.  Phase 4 drilling (approx. 3,000m) is set to initially focus on testing the interpreted northern continuity (Big Red Extension) of the shallow, thick, gently dipping, and high-grade lithium mineralisation intersected at Big Red, which includes:   29m @ 1.36% Li2O from 38m (KHRC011) 1  27m @ 1.32% Li2O from 64m (KHRC017) 2  23m @ 1.03% Li2O from 53m (KHRC031) 3  23m @ 1.19% Li2O from 44m (KHDD001)1  22m @ 1.24% Li2O from 23m (KHDD006) 4 Drilling is then planned to shift to testing of high-potential optimised resistivity anomaly targets at Quokka and Western Grey. Future Battery Minerals Ltd (ASX: FBM) (FBM or the Company) is pleased to advise that the Phase 4 drilling program in the northern area of its 100%-owned Kangaroo Hills Lithium Project (KHLP) in Western Australia has now commenced.

Spodumene mineralisation within LithiumCaesium-Tantalum (LCT) pegmatites was discovered during regional exploration drilling of the Nepean Nickel Project in late 2022. Exploration efforts to date have significantly expanded on these initial results, with two subsequent rounds of drilling totalling 47 holes and over 6,000m. This drilling has identified the Big Red Prospect, an outcropping, north-dipping pegmatite returning an intercept of 29m @ 1.36% Li2O from 38m 5, and with spodumene identified as the dominant lithium mineral. Through the implementation of regional target generative work involving mapping, geophysics and geochemistry, six additional high priority prospects have been identified. These high priority prospects have the potential to host further LCT pegmatites. The location of the KHLP provides significant advantages to FBM. Located on the doorstep of a premier mining district, the Goldfields of Western Australia, and specifically Kalgoorlie (50km east of the KHLP), host a professional mining and exploration workforce. This provides FBM with ready access to skilled labour and regional infrastructure critical to the development of any future mining project. The Goldfields region is also a notably lithium endowed province of Western Australia, with numerous operating and developing lithium projects. Notably, the KHLP is only 30km west of the Mt Marrion Lithium Mine operated by Mineral Resources (ASX: MIN). The KHLP site is accessible via a sealed road leading south from Coolgardie, ensuring FBM has continuous access all year-round. 5 Refer to ASX Announcement on 20 March 2023 – LCT – Pegmatite Discovery Confirmed at Kangaroo Hills Future Battery Minerals Ltd info@futurebatteryminerals.com.au Suite 10, 38 Colin St, West Perth WA 6005 +61 8 6383 7817 ABN 91 148 966 545 futurebatteryminerals.com.au ASX: FBM Follow Us 4
