The Apex Project is adjacent to the historic Apex Mine, a past- producing carbonate-hosted system known for exceptionally high-grade germanium-gallium- copper mineralisation¹. • District attracting renewed major interest: the historic Apex Mine was recently acquired by NASDAQ-listed Blue Moon Metals, underscoring renewed market interest in one of the United States' notable germanium-gallium-bearing polymetallic systems². • Aligned to secure critical mineral supply: the Company is progressing a strategy that integrates high-impact critical mineral exploration with germanium enrichment technologies and downstream application development, supporting secure US and EU supply chains for metals of growing strategic importance. • Built on high-resolution, multi-source data: high-resolution WorldView-3 satellite imagery (0.31 m panchromatic; 1.24 m VNIR) was combined with available ASTER and Sentinel-2A multispectral data, published geological mapping and a LiDAR-derived Digital Elevation Model, across ~65 km² of detailed coverage within a ~1,500 km² regional study area. • Clear signatures: target generation focused on discrete iron oxide anomalies and strong goethite signatures, characterizing the Apex mining area, clay-carbonate-silica alteration responses, and NW- and NE-trending fault corridors and their intersections interpreted as potential primary structural controls for carbonate-hosted polymetallic mineralisation in the district. • Additional targeting: WorldView-3 short-wave infrared (SWIR) multispectral data has been separately ordered and is expected to further refine the clay-carbonate-silica alteration interpretation and target ranking ahead of field work. • Further exploration: results will directly guide the Company's upcoming field program, including ground-truthing, mapping and sampling of priority targets ASX Announcement Released 22 June 2026 2 To learn more about this announcement, click here Battery Age Minerals Limited (ASX: BM8) (“Battery Age” or “the Company”) is pleased to report the interpretation results of a high-resolution satellite-based remote sensing study completed over its Apex Germanium-Gallium Project (“Apex” or “the Project”), located approximately 20 km southwest of St George, Utah, USA. The survey was interpreted by Brisbane-based remote sensing consultancy Geo Spectra Pty Ltd and covers the Company's Apex North, East and South tenements. Refer to Figure 1 for the project location. Figure 1: Location of the Apex claim blocks The passage of potentially mineralising fluids is indicated by the alteration of the host rocks and the formation of new mineral assemblages along the path of migration. From the study of these, alteration mineral maps (iron oxide/goethite and clay-carbonate-silica), structural interpretation and geological maps were integrated to identify areas where favourable alteration assemblages coincide with favourable structures (in particular northwest-trending strike-slip faults of the type ASX Announcement Released 22 June 2026 3 interpreted to control the known Apex mineralisation) and favourable host lithologies, principally the Permian Pakoon Dolomite and, to a lesser extent, the Lower Mississippian Redwall Limestone. On the basis of this integration, Battery Age has identified multiple first and second-priority targets across the Apex tenements for follow-up field exploration. These targets represent areas identified from the integration of remote sensing datasets as having characteristics analogous to the historic Apex mine. There is no certainty that further exploration will result in the identification of mineralisation, and the targets should not be interpreted as an indication that economic mineralisation has been discovered. Refer to Figures 2 to 5 for the identified target areas and supporting interpretation detail.

Battery Age CEO, Sebastian Kneer, commented: "These results mark an important step forward for the Apex Project. By integrating high-resolution satellite data with our structural and geological interpretation, we've defined 14 high-priority targets across all three tenements — several in settings we consider analogous to the historic Apex Mine, one of the highest-grade germanium-gallium systems documented in the United States. NASDAQ-listed Blue Moon Metals recent acquisition of the Apex Mine reflects renewed interest in this district, and we believe Battery Age is exceptionally well positioned, surrounding and adjacent to that system, at a time when secure germanium and gallium supply has become a strategic priority for both the US and EU. Importantly, we now have a clear, sequenced path forward. Incoming WorldView-3 SWIR data will sharpen our target ranking, followed by ground-truthing, mapping and sampling, building toward testing of the most prospective areas. We look forward to a steady flow of news as the field program advances." ASX Announcement Released 22 June 2026 7 About the Project Located on the eastern flank of the Beaver Dam Mountains, approximately 22 km west of St George and 9 km north of the Arizona border, the Apex Project comprises claim blocks located adjacent to the historic Apex mine. The project benefits from exceptional infrastructure including highway access, proximity to power and rail, and year-round field access. The Apex Project is centred around the historic Apex mine, a carbonate-hosted polymetallic copper-lead-zinc-germanium-gallium occurrence. Mineralisation in the district is interpreted to be a structurally controlled, breccia- and carbonate-hosted base metal system, with germanium and gallium occurring as by-product metals associated with iron-rich dolomite and sulphide assemblages. The remote sensing survey was designed to map alteration mineralogy and structural controls associated with this style of mineralisation across the Company’s Apex tenements, and to generate targets ahead of planned field program. Survey Methodology The survey was based on newly purchased WorldView-3 satellite imagery (operated by Maxar), comprising 0.31 m resolution panchromatic data and 1.24 m resolution multispectral VNIR data across 8 bands (0.4–1.04 μm). This purchased Pan and VNIR dataset was combined with publicly available ASTER and Sentinel-2A multispectral satellite imagery, a 30 m regional Digital Elevation Model (DEM) and a higher-resolution LiDAR-derived DEM covering the district surrounding the WorldView-3 coverage area. WorldView-3 SWIR data (8 bands, 1.19–2.37 μm) has been separately ordered and will be used to refine the clay-carbonate-silica alteration mapping once received. Processing and interpretation were undertaken in ENVI 6.1, QGIS and ArcGIS Pro, and comprised the following principal steps: • Radiometric and geometric correction of the satellite imagery and construction of a vegetation mask; • Generation of RGB band composites and band ratios to characterise the mineral systems of the area; • Mapping of ferric iron oxide minerals (hematite and goethite), including a goethite intensity map of stronger signatures; • Mapping of silica intensity using ASTER thermal infrared (TIR) data, and clay and carbonate (calcite-dolomite) minerals using Sentinel-2A and ASTER data; • Full structural analysis of the Apex area using high-resolution WorldView-3 panchromatic and VNIR imagery together with the regional and LiDAR-derived DEMs; • Compilation of a geological map of the Apex area derived from WorldView-3 imagery and the published 1:100,000 geological map of the St George, Utah area; and • Integration of the mineral alteration maps, structural interpretation and geological map for camp-scale target generation. Alteration Mineral Mapping Results Ferric iron oxide assemblages (hematite and goethite) are an important feature of carbonate- hosted polymetallic and related metallic mineralisation in the district. While regional iron oxide trends, mostly oriented north-south, are largely associated with iron-bearing red sandstone units, the survey also identified a number of subtle, small, discrete iron oxide and goethite anomalies. Several of these are spatially coincident with known historic polymetallic occurrences, including the Apex mine itself, and are considered important indicators for target generation. ASX Announcement Released 22 June 2026 8 Clay minerals, carbonates (calcite and dolomite) and silica were mapped using ASTER and Sentinel-2A data. The presence of silicification and minor clays in association with iron oxides is considered a favourable indicator for the presence of mineralisation within this carbonate-hosted polymetallic system. This mapping is intended to be refined using WorldView-3 SWIR data as it becomes available. Structural Analysis Structural corridors are interpreted to be a key control on the migration of hydrothermal fluids and the formation of carbonate-hosted polymetallic (Cu-Pb-Zn-Ga-Ge) mineralisation in the Apex region. Structural interpretation was carried out over the 65 km² WorldView-3 coverage area using the regional and LiDAR-derived DEMs, which allow fault zones to be mapped from their geomorphic expression (typically linear depressions formed by enhanced erosion along more permeable fault- zone rocks). The Apex area lies within the Basin and Range Province, which has a structural history of east- west oriented compression followed by east-west oriented extension. Two principal fault sets were identified: dominantly north-south striking faults with vertical (thrust/normal) movement, related to large-scale rotation of fault-bounded blocks during extension; and northwest-southeast and northeast-southwest striking fault sets that accommodated lateral movement during the earlier compressional phase (sinistral on NW-SE faults and dextral on NE-SW faults). These oblique fault sets, and their intersections with the north-south fault set, are interpreted as favourable structural settings for carbonate-hosted polymetallic mineralisation, consistent with the structural setting of the historic Apex mine. Next Steps The remote sensing results will be used to directly inform the design of Battery Age's upcoming field exploration program at Apex. Planned follow-up work is expected to include: • Ground-truthing and geological mapping of the first- and second-priority targets identified from the remote sensing study; • Surface rock chip and/or soil geochemical sampling over priority target areas to test for anomalous Ga-Ge-Pb-Zn geochemistry; and • Prioritisation of targets for more detailed follow-up exploration, including potential geophysical surveys and drill testing, subject to the results of the field program. The Company will provide further updates as the field program is planned and results become available.
