Excitingly, the mineralisation continues to remain open at depth. “Following on from the initial success of the deep drilling program, several additional diamond holes are being planned to in-fill the depth extensions, specifically to target Inferred Mineral Resources and to test the up-dip component of the Theia Deeps mineralisation to the north. “Drill results for a 20m x 20m in-fill program for the Stage 2 pit design at Theia have also been received, with results continuing our de-risking of the Mandilla mine plan. Drill spacing in the respective area was previously at 20m x 40m, with several additional programs of drilling required to upgrade the entire Stage 2 pit to Measured Resource classification ahead of mining. “The in-fill program on the Stage 1 pit design at Theia is ongoing, with 115 holes completed for approximately 11,150 metres. Assay turnaround times have been slow, with results received for less than 20% of the holes drilled. “Contract negotiations on the Think Big early revenue opportunity are nearing completion, with all work scopes in relation to advancing Think Big to production progressing contemporaneous with negotiations, in line with the Letter of Intent and as if the contract was in full force. Additional geotechnical drilling has been completed, as has a 6,000 metre in-fill RC program. The Native Vegetation Clearing Permit (NVCP) and Mine Development Closure Plan (MDCP) have both been submitted. “Furthermore, work on the Mandilla DFS is progressing, with capital and operating costs for the process plant currently under internal review. Additionally, early parts of the scope for the Independent Technical Expert’s Report to facilitate debt financing are also underway. Work is ongoing to finalise the location of key infrastructure items to support the mine development which, once complete, will enable formal submission of the NVCP and MDCP.” JOIN ASTRAL RESOURCES’ INVESTOR HUB Visit Astral Resources' Investor Hub or scan the QR code to be a part of Astral’s interactive hub.

Mineralisation encountered to date is consistent with the current geological model for Theia, comprising broad, consistent grade intervals within laterally continuous zones of quartz-sulphide veining that dip shallowly to the south‑west. Following the completion of this program, the RC rig relocated to the Stage 1 pit, with a further 115 holes for 11,150 metres completed. This program is ongoing, with the majority of the assay results pending. To date, assay results have been received for less than 20% of the completed holes. Further in-fill drilling of the Stage 2 pit will be completed post completion of the Stage 1 in-fill program. In-fill drilling is continuing, with the intention that both Stages 1 and 2 of the Theia open pit are progressively in-filled to a Measured Resource category as the Mandilla Gold Project is advanced towards a Final Investment Decision. CURRENT AND FUTURE EXPLORATION WORK PROGRAMS Two drill rigs are currently operating at Mandilla. The DD program is ongoing, with nine holes of the expanded 11-hole (6,000m) program completed. Additional drill holes are currently being planned, both to in-fill the recently identified gold mineralisation to an Inferred category and to further test the extent of Theia mineralisation both up and down-dip. Meanwhile, the RC drill rig is continuing the in-fill program on the remainder of the Stage 1 Theia open pit, targeting a 12.5m x 12.5m drill density to support a further increase in Measured Resources. Approximately 11,150 metres have been completed of the planned 23,000-metre program. 11 astralresources.com.au ASX: AAR | Sterilisation drilling at Mandilla will continue pending heritage clearance surveys. Both RC and diamond drilling is planned for the Kamperman Deposit (Feysville) and the Spiders complex (Spargoville) once heritage clearance surveys have been completed.

The area hosts world-class deposits such as the Golden Mile Super Pit in Kalgoorlie, owned by Northern Star Resources Limited (ASX: NST), and the St Ives Gold Mine approximately 20 kilometres to the south-east of Kambalda, owned by Gold Fields Limited, as well as the Beta Hunt Gold Mine immediately to the south of Kambalda, owned by Westgold Resources Limited (ASX: WGX). Mandilla is covered by existing Mining Leases which are not subject to any third‐party royalties other than the standard WA Government gold royalty. The Mandilla Gold Project includes the Theia, Iris, Eos and Hestia deposits. Gold mineralisation at Theia and Iris is comprised of structurally controlled quartz vein arrays and hydrothermal alteration close to the western margin of the Emu Rocks Granite and locally in contact with sediments of the Spargoville Group. Significant NW to WNW-trending structures along the western flank of the project are interpreted from aeromagnetic data to cut through the granitic intrusion. These structures are considered important in localising gold mineralisation at Theia, which has a mineralised footprint extending over a strike length of more than 1.6km. A second sub-parallel structure hosts gold mineralisation at the Iris deposit. The mineralised footprint at Iris extends over a strike length of approximately 700 metres, combining with Theia to form a mineralised zone extending over a strike length of more than 2.3 kilometres. At Eos, located further to the south-east, a relatively shallow high-grade mineralised palaeochannel deposit has been identified which extends over a length of approximately 900 metres. A primary gold source is also present, with further drilling required to determine both the nature and structural controls on mineralisation and its extent. Mineralisation delineated over approximately 1,300 metres of strike at the Hestia deposit, located approximately 500 metres west of Theia, is associated with a shear zone adjacent to a mafic/sediment contact, interpreted to be part of the major north-south trending group of thrust faults known as the Spargoville Shear Corridor. Locally, the Spargoville Shear Corridor hosts the historically mined Wattle Dam gold mine (266koz at 10.6g/t Au) and, further to the north, the Ghost Crab/Mt Marion mine (>1Moz). The mineralisation at Hestia, which is present in a different geological setting to the bedrock mineralisation at Theia and Iris, remains open both down-dip and along strike. In April 2026, Astral announced a Mineral Resource Estimate (MRE) of 53.5Mt at 1.0 g/t Au for 1.74Moz of contained gold2 for the Mandilla Gold Project. 2 - Mandilla JORC 2012 Mineral Resource Estimate: 1.3Mt at 1.3g/t Au from 57koz Measured Mineral Resources, 32.6Mt at 1.0g/t Au for 1,092koz Indicated Mineral Resources and 19.6Mt at 0.9g/t Au for 588koz Inferred Mineral Resources (refer to Astral ASX announcement dated 21 April 2026) 13 astralresources.com.au ASX: AAR | Metallurgical testing undertaken on each of the main deposits at Mandilla – Theia, Iris, Eos and Hestia – has demonstrated high gravity recoverable gold, fast leach kinetics and exceptional overall gold recoveries with low reagent consumptions and coarse grinding3,4. In June 2025, Astral announced the results of a Preliminary Feasibility Study for Mandilla (Mandilla PFS), which also included the mining of gold deposits at Feysville. It was based on a standalone project comprising seven open pit mines feeding a 2.75Mtpa processing facility, producing 95koz per year for the first 12 years. The base case gold price assumption for the Mandilla PFS was A$4,250/oz and demonstrated a Net Present Value (8% discount rate) (NPV8) of $1.4 billion5. At a A$6,250 gold price, the NPV8 increases to $2.9 billion. Four open-pit mines at Mandilla were included in the Mandilla PFS (Theia, Hestia, Eos and Iris), and three open-pits mines at Feysville (Kamperman, Think Big and Rogan Josh). A map of Mandilla illustrating both the local area geology and mineral deposits is set out in Figure 4.
