Announcement PDF 5 August 2024 ASX ANNOUNCEMENT FBM SIGNIFICANTLY EXPANDS FOOTPRINT IN THE GOLDFIELDS Highlights  FBM expands landholding in highly prospective zones of the W.A. Goldfields by 160%.  New applications in proximity to existing Kangaroo Hills and Miriam Lithium Projects.  Excellent discovery potential offered for both lithium and gold mineralisation. Future Battery Minerals Ltd (ASX: FBM) (FBM or the Company) announces the submission of additional Exploration and Prospecting Lease Applications over several areas proximate to its Kangaroo Hills and Miriam Lithium Projects in the Western Australian Goldfields region. These areas of new tenure application are considered highly prospective by FBM for both lithium and gold mineralisation. FBM Managing Director and CEO, Nick Rathjen, commented: “We are pleased to have identified and pegged this attractive ground holding so close to our existing footprint in the region. Its prospectivity lies squarely within our core skillset and focus areas of lithium whist also having gold exploration potential. “FBM’s plans for the ongoing exploration and advancement of the Kangaroo Hills and Miriam Lithium Projects are materially unchanged, as is the continued prioritisation of evaluation expenditure to its Western Australian projects. Initial low-cost field exploration activities are planned to commence on the newly acquired ground as tenements are granted. Desktop target generative exercises will also be conducted on the tenure during the application phase to allow fast-tracking and testing of prospective targets.” Expansion of FBM landholding in W.A. Goldfields FBM has recently staked and submitted applications to the Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) for two (2) Exploration Leases and five (5) Prospecting Leases totalling approximately 65km2. The ground subject of these applications is considered highly prospective for both lithium and gold mineralisation and is proximate to the Company’s existing W.A. Goldfields projects, being the Kangaroo Hills and Miriam Lithium Projects (refer Figure 1). The applications significantly expand FBM’s landholding in the W.A. Goldfields region by approximately 160%, building on the existing footprint of the Kangaroo Hills and Miriam Lithium Projects (approx. 19km2) and non-core Saints Nickel Project (approx. 20km2).

The ground has been applied for following ongoing technical investigations into LCT pegmatite potential across the broader W.A. Goldfields region. FBM has progressed third party objections to the new tenure applications and is now negotiating Heritage Protection Agreements (HPA) with relevant native title parties. Granting of the tenure is expected on completion of the relevant HPA’s.

Additionally, two applications P15/6813 and P15/6681 are contiguous to the Kangaroo Hills Lithium Project, offering both further prospectivity for LCT pegmatites and a larger land holding for optimal future development of the Kangaroo Hills lithium system. This brings total land holding in the Kangaroo Hills region to 56.7km2 providing further exploration upside. KHLP North overlies an extension of the same greenstone unit which hosts the KHLP and Miriam spodumene bearing pegmatites. The tenement is approximately 4km northwest of the Miriam project and is well accessed by the Great Eastern highway. Previous tenement holders identified a 4km +80ppm Li anomaly in soil samples which still remains untested. The Li anomaly is coincident with underlying greenstone lithologies and only one pegmatite outcrop has been located in the area. FBM eye’s similar characteristics to the KHLP and Miriam LCT pegmatites highlighting this area as a high priority target when granted. The KHLP West project is located approximately 6km directly east of the Big Red Lithium pegmatite. The area has been subject to limited historic exploration work, however a wide spaced drilling programme conducted by Jervois Mining Ltd in 2008 intercepted lithologies logged as pegmatite in one drill hole plotting within the current application area. LCT elements were not assayed and FBM will commence work to identify the LCT potential of pegmatites in this region, this work will include mapping and surface sampling to aid in future drill hole targeting. No current known gold occurrences exist within the application area, however the ground is in close proximity to the Gibraltar and Gibraltar East historic gold mines and is located on the same underlying greenstone unit as the Bullabulling Gold Mine (3.2Moz) 1 operated by Norton Goldfields Pty Ltd. FBM will further evaluate the ground for potential gold mineralisation in tandem with the LCT pegmatite exploration. 1 Refer to Norton Goldfields website – Bullabulling Gold Project 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 3 Figure 2 – Kangaroo Hills Tenure Location 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 Figure 3 KHLP North Li Soil Anomaly (see historical sampling details JORC Table 1) Broader Goldfield Region The Kalgoorlie North project consists of one exploration lease application totalling an area of 27.9km2 located 45km northeast of Kalgoorlie. The north Kalgoorlie region is home to numerous operating and historic gold mines including Kanowna Belle, currently operated by Northern Star Resources Ltd and has produced 5.4Moz gold since 1993 2. Smaller operations such as the Gordon Sirdar mine operated by FMR Investment Pty Ltd are located only 11km south. The tenement is well accessed by roads leading to these operations and numerous station and exploration tracks. The tenure has been poorly tested for gold or LCT pegmatites, the underlying geology consists of Archean greenstone lithologies and is flanked to the north by granite, this highlights the potential for LCT pegmatite occurrences providing adequate host geology and granitic source rock.

Since 2019, the company has been focused on the exploration and advancement of its Lithium and Nickel projects in Western Australia and Nevada. FBM now has a significant landholding in both WA and Nevada which overlies geology prospective for precious metal mineralisation. As such, the Company also plans to initiate a gold and multi-commodity review of its broader project portfolio, including its South Australian assets, this includes both desktop evaluation and low-cost ground exploration to further progress these opportunities within the portfolio.

Our flagship asset is the 100%-owned Kangaroo Hills Lithium Project (KHLP). The KHLP is located in the Goldfields of Western Australia, approximately 17km south of the major township of Coolgardie, and hosts the exciting Big Red, Rocky and Potoroo hard rock lithium discoveries. Immediately north to the KHLP is the Miriam Project, the recent acquisition of which doubled our regional footprint. Miriam is located immediately along strike from the KHLP and holds a large historic lithium soil anomaly extending from an outcropping spodumenerich pegmatite, providing a significant opportunity for future discovery success. These project areas are being rapidly advanced in parallel by FBM’s experienced team, focusing on resource growth, metallurgical test work and development readiness. The Goldfields are a lithium endowed province of Western Australia, with numerous operating and developing Lithium projects. Notably, the KHLP is only 30km’s west of the Mt Marrion Lithium Mine operated by Mineral Resources Ltd (ASX: MIN). KHLP and Miriam are accessible via a sealed road leading south from Coolgardie, ensuring the Company has continuous access all year-round. Our other key portfolio asset is the Nevada Lithium Project (NLP). A large-scale, high-grade maiden lithium claystone Mineral Resource Estimate (MRE) was recently declared for the Lone Mountain deposit within the NLP, with this MRE being delivered less than 12 months from discovery. The business is evaluating a range of potential commercialisation routes for the NLP. About Lithium Lithium is a soft silvery-white metal which is highly reactive and does not occur in nature in its elemental form. In nature it occurs as compounds within hard rock deposits, salt brines and claystone. Lithium and its chemical compounds have a wide range of industrial applications resulting in numerous chemical and technical uses. Lithium has the highest electrochemical potential of all metals, a key property in its role in lithium-ion batteries.
