The Theia RC in-fill drilling program is also continuing. • 1 - 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) 2 astralresources.com.au ASX: AAR | Astral Resources’ Managing Director Marc Ducler said: “These latest Theia Deeps drilling results represent another highly encouraging development, delivering strong outcomes on two important fronts – confirming the presence of a zone of wide, high-grade gold mineralisation at depth and demonstrating the potential to extend the deposit further to the south. “The standout is AMRCD377 with intercepts of 23m at 2.39g/t Au and 33m at 5.02g/t Au – below the current Mineral Resource shell. This is similar to the mineralisation intersected previously in AMRCD378, which intersected 52.75m at 4.67g/t Au, providing further evidence of a potentially significant high-grade zone beneath the current Theia Mineral Resource. “These are important results as we work to establish the scale and continuity of higher-grade mineralisation at depth that could potentially support future underground extraction once we reach the economic base of the Theia Open Pit. “Equally encouraging are the results from drill-holes AMRCD466 and AMRCD467, drilled approximately 150 metres south of the current Mineral Resource, where we have intersected further significant zones of open pit gold mineralisation, highlighting further opportunities for resource growth at Theia. “With 18 of the planned 21 diamond holes now completed, the Theia Deeps program is nearing completion, while the Theia Reverse Circulation (RC) in-fill drill program is also continuing. “Looking ahead, preliminary approval has been received from the recently completed Spargoville and Kamperman heritage surveys, with planning underway to complete the necessary drill pad preparation. Once complete, the RC rig will be relocated to Spargoville to undertake a phased 55-hole/10,000 metre RC program and the DD rig will be moved to Kamperman for a 3-hole/1,000 metre DD program.” Astral Resources NL (ASX: AAR) (Astral or the Company) is pleased to report assay results for a further three diamond drill-holes completed as part of the ongoing deep Diamond Drill (DD) program at the Theia Deposit, part of the 100%-owned Mandilla Gold Project (Mandilla), located 70km south of Kalgoorlie in Western Australia (Figure 1).

MANDILLA DIAMOND DRILLING UPDATE The Theia Deeps DD program testing depth extensions of the cornerstone 1.4Moz1 Theia Deposit has been achieving considerable success, with the program expanded on several occasions and now encompassing a planned 21 holes for 11,000m. To date, significant depth extensions have been identified, with the Theia Deeps program now focused on testing both the width and strike length of this newly discovered mineralisation. An isometric view showing the drill-hole collar locations for the DD program is shown in Figure 2. 4 astralresources.com.au ASX: AAR | Figure 2 – Isometric view of the Theia Deposit showing the MRE block model, the drill traces for the completed and planned deep DD holes and the cross-section locations. Assay results for holes AMRCD377, AMRCD466 and AMRCD467, totalling 1,819.3 metres, have now been received. AMRCD377 In our 17 August 2026 ASX announcement, we reported that DD hole AMRCD378 had returned a wide, high-grade zone of gold mineralisation of 52.75m at 4.67g/t Au from 445.25m, occurring just beneath the base of the current Mineral Resource shell. Subsequently DD hole AMRCD377 was drilled 60 metres north-east of AMRCD378 on the same section. Best results for AMRCD377 include: • 1m at 10.4g/t Au from 20m • 7m at 1.60g/t Au from 38m • 13m at 1.81g/t Au from 94m • 16m at 1.01g/t Au from 127m including 1m at 12.0g/t Au from 139m • 1m at 9.87g/t Au from 270m • 23m at 2.39g/t Au from 418m including 0.63m at 14.3g/t Au from 427.37m and 0.3m at 107.9g/t Au from 431.58m • 33m at 5.02g/t Au from 450m including 0.34m at 20.3g/t Au from 453.52, 0.3m at 52.5g/t Au from 468.15m, 1.32m at 81.2g/t Au from 474.7m and 0.32m at 69.2g/t Au from 481.34m • 43.02m at 0.76g/t Au from 491.98m • 20m at 0.72g/t Au from 541m including 0.3m at 97.1g/t Au from 553.07m 5 astralresources.com.au ASX: AAR | AMRCD377 returned two high-grade intersections, 23m at 2.39g/t Au from 418m and 33m at 5.02g/t Au from 450m, with both zones located below the base of the April 2026 Mineral Resource pit shell. A further two zones of broad, lower grade gold mineralisation were intercepted deeper in the hole. When aggregated, the four intercepts total 143m at 1.87g/t Au from 418m. Cross-section A-A’, as located in Figure 2, is shown below in Figure 3. 6 astralresources.com.au ASX: AAR | Figure 3 – Cross-section view of the Theia Deposit showing AMRCD377 and AMRCD378. 7 astralresources.com.au ASX: AAR | Encouragingly, early interpretations indicate these higher-grade results associated with zones of greater dilation and an increasing frequency of quartz veining could potentially support future extraction by underground mining methods below the economic base of the proposed Theia open pit. AMRCD466 and AMRCD467 DD holes AMRCD466 and AMRCD467 were drilled approximately 150 metres to the south of the current Theia Mineral Resource. They were drilled to test for dip extensions to the south-west of the main mineralised zone at Theia. Best results for AMRCD466 include: • 0.3m at 97.1g/t Au from 112.42m • 42m at 0.89g/t Au from 285m including 1m at 14.1g/t Au from 302m • 5m at 1.40g/t Au from 578m • 6m at 13.2g/t Au from 595m including 0.5m at 153.6g/t Au from 596.88m AMRCD466 intersected a large zone of more intense alteration, increased dilation and elevated quartz veining, returning 42m at 0.89g/t Au from 285m down-hole located well outside the April 2026 MRE pit shell. With the previously observed periodicity of alteration intensity, increasing dilation and elevated quartz veining, another zone of gold mineralisation was observed towards the bottom of the hole with a high- grade interval of 6m at 13.2g/t Au from 595m reported. AMRCD467 Best results for AMRCD467 include: • 13m at 0.86g/t Au from 75m • 11.2m at 5.82g/t Au from 220.19m, including 1.45m at 23.5g/t Au from 222.15m and 0.3m at 73.5g/t Au from 228.1m • 7.5m at 4.00g/t Au from 257.7m including 1m at 21.5g/t Au from 260m • 13.7m at 1.70g/t Au from 282.3m including 1m at 10.4g/t Au from 294m • 35.9m at 1.57g/t Au from 303.1m including 0.3m at 62.5g/t Au from 329.2m • 3.86m at 1.63g/t Au from 584m Similarly, DD hole AMRCD467, which was drilled 110 metres east of AMRCD466, returned several zones of gold mineralisation, 11.2m at 5.82g/t Au from 220.2m (inside the April 2026 MRE pit shell), 7.5m at 4.00g/t Au from 257.7m, 13.7m at 1.7g/t Au from 282.3m and 35.9m at 1.57g/t Au from 303.1m, which were all located outside the April 2026 MRE pit shell.

CURRENT AND FUTURE EXPLORATION WORK PROGRAMS Both Reverse Circulation (RC) and DD rigs continue operating at Mandilla. The DD program is ongoing with 18 holes of the expanded 21-hole (11,000m) program now complete. In-fill RC drilling of the Theia Stage 1 open pit is ongoing, with 28,350 metres completed of the 431- hole (44,400m) program. Heritage surveys are in progress to clear the remaining development footprint for the Mandilla Gold Project. Pad preparation is scheduled for mid-October for both the Spiders Deposit (Spargoville) and Kamperman Deposit (Feysville). This will allow both RC and DD to commence at the Spiders and Kamperman respectively during this current December Quarter.

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). 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. 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. 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) 3 ASX Announcement 6 June 2022 “Outstanding metallurgical test-work results continue to de-risk Mandilla.” 4 ASX Announcement 17 September 2024 “Outstanding metallurgical results further de-risk Mandilla.” 11 astralresources.com.au ASX: AAR | 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). The Company is currently progressing a Definitive Feasibility Study for Mandilla (Mandilla DFS). The Mandilla DFS is forecast for completion during the March Quarter 2027, with the projected timing reliant on the completion of native title heritage surveys, which are required for the submission of approval documentation. Simultaneously, the Company is pursuing an early mining opportunity at the Think Big deposit at Feysville, which could produce cash flow during the June Quarter 2027.
