Announcement PDF ASX Announcement ASX: AAR 28 JANUARY 2025 DIAMOND DRILLING DELIVERS BEST RESULT YET AT THEIA DEPOSIT AHEAD OF MANDILLA RESOURCE UPGRADE Diamond drill-hole MDRCD918 delivers multiple high-grade intersections which, when aggregated, return an exceptional 1,079 gram-metres along the length of the hole HIGHLIGHTS • Assay results received for the final two holes – MDRCD917 and MDRCD918 – of the recent four-hole (1,762-metre) in-fill diamond drilling (DD) program at the Theia Deposit, part of Astral’s 100%-owned 1.3Moz2 Mandilla Gold Project near Kalgoorlie. • Best results in DD hole MDRCD918 include: • 1.0 metre at 223.3g/t Au from 15 metres; • • 1.0 metre at 12.2g/t Au from 149 metres; • 9.6 metres at 27.6g/t Au from 194 metres including 0.95 metres at 227.6g/t Au from 197.25 metres and 1 metre at 33.1g/t Au from 199 metres; • 2.4 metres at 169.1g/t Au from 225 metres; • 2.0 metres at 4.15/t Au from 270 metres; • 3.6 metres at 7.14g/t Au from 303 metres including 0.4 metres at 54.5g/t Au from 303.35 metres; • 12 metres at 0.52g/t Au from 333 metres; and • 24.9 metres at 4.14g/t Au from 362 metres including 0.7 metres at 11.3g/t Au from 362.3 metres, 0.3 metres at 11.3g/t Au from 364.55 metres, 1.0 metre at 60.6g/t Au from 375 metres and 0.3 metres at 24.6g/t Au from 380.7 metres. Best results in DD hole MDRCD917 include: • 72.2 metres at 1.15g/t Au from 326 metres including 0.3 metres at 34.9g/t Au from 328.35 metres and 0.62 metres at 25.6g/t Au from 396 metres; • 2.2 metres at 15.4g/t Au from 317.6 metres including 1.05 metres at 29.9g/t Au from 317.62 metres; and • 22 metres at 0.57g/t Au from 105 metres. • MDRCD918 has delivered several well-mineralised intercepts which, when aggregated, return a cumulative 1,079 gram-metres 1 of gold along the length of the hole. In terms of the grammetres metric, this is the most mineralised of all holes drilled thus far at Mandilla. • These latest DD in-fill results demonstrate a strong correlation with the mineralisation wireframes in the current Mineral Resource Estimate (MRE) suggesting that the results are likely to support the upgrade of Inferred Mineral Resources into the higher confidence Indicated category. 1 Gram-metres or GxM is the product of the assayed grade of the reported interval multiplied by the length of the reported interval. Astral Resources Suite 2, Lyall St, South Perth WA 6151 T +61 8 9382 8822 E info@astralresources.com.au astralresources.com.au | ASX: AAR • Following receipt of these latest results, work has commenced on updating the Mandilla MRE which is expected to be completed later in the March Quarter 2025. • Assay results have also been received for a three-hole (360-metre) reverse circulation (RC) drill program testing for possible extensions to the mineralisation at the southern extent of the Kamperman Deposit at the Feysville Gold Project. Best results from this program included 6 metres at 1.04g/t Au from 114 metres in FRC394. • A three-hole (350-metre) DD program currently underway at Kamperman is designed to increase the understanding of controls associated with high-grade mineralisation and to provide sample material for metallurgical test work. This will be followed by a 17-hole (1,610-metre) geotechnical drill program at the Kamperman, Rogan Josh and Think Big deposits. • An air-core (AC) program commenced on 20 January 2025 at Feysville, encompassing six lines of drilling (4.3 line-kilometres) designed to test the Central Feysville Anticline and four lines (1.7 line-kilometres) designed to test several structural targets identified at the southern tenements. Astral Resources’ Managing Director Marc Ducler said: “The four-hole diamond drill program completed in December 2024 returned an average of 401 grammetres when aggregating the reported mineralised intersections along the length of each hole. “The final hole - MDRCD918 returned the best ever metal accumulation in a single hole at Mandilla with an outstanding 1,079 gram-metres. “Given the key objective of this drill program was to upgrade deeper Inferred Mineral Resources at Theia to the higher confidence Indicated category, these results provide encouragement that we may have achieved this goal. “Cube Consulting is currently working on an update to the Mandilla MRE. Once complete, this will pave the way for the commencement of detailed mine design and scheduling for the upcoming Mandilla PreFeasibility Study. The MRE is expected to be completed later in the March Quarter 2025. “Programs of diamond and air core drilling are currently underway at Feysville. The diamond drilling at the Kamperman deposit is designed to improve our understanding of the controls to the high-grade mineralisation which has previously been intersected in several holes. The air core drilling is designed to investigate several promising structural targets, with 6.3 line-kilometres of drilling planned, to see if we can vector into potential new discoveries along trend from the known deposits.” Astral Resources NL (ASX: AAR) (Astral or the Company) is pleased to report assay results for the final two holes of a four-hole (1,762-metre) in-fill DD program at the Theia Deposit, part of the 100%owned Mandilla Gold Project (Mandilla), located approximately 70km south of Kalgoorlie in Western Australia. This announcement also includes assay results from a three-hole (360-metre) extensional RC program at the Kamperman Deposit, part of the 100%-owned Feysville Gold Project (Feysville), located approximately 14km south of Kalgoorlie in Western Australia. A map illustrating the location of both Mandilla and Feysville is set out as Figure 1. astralresources.com.au ASX: AAR | 2 Figure 1 – Map illustrating the location of the Mandilla and Feysville Gold Projects. MANDILLA GOLD PROJECT The Mandilla Gold Project is situated in the northern Widgiemooltha greenstone belt, approximately 70 kilometres south of the significant mining centre of Kalgoorlie, Western Australia. 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 south of Kambalda owned by Gold Fields Limited, as well as the substantial Beta Hunt Gold Mine 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. astralresources.com.au ASX: AAR | 3 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 600 metres, combining with Theia to form a mineralised zone extending over a strike length of more than 2.2 kilometres. At Eos, located further to the south-east, a relatively shallow high-grade mineralised palaeochannel deposit has been identified and which extends over a length of approximately 600 metres. Fresh rock gold mineralisation is also present with further drilling required to determine both the nature and structural controls on mineralisation and its extent. Mineralisation delineated over approximately 800 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 bedrock mineralisation at Theia and Iris, remains open both down-dip and along strike. In July 2023, Astral announced a Mineral Resource Estimate (MRE) of 37Mt at 1.1 g/t Au for 1.27Moz 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 grinding 3,4. In September 2023, Astral announced the results of a Scoping Study for Mandilla (Scoping Study) which – based on a standalone project comprising three open pit mines feeding a 2.5Mtpa processing facility, producing 80 to 100koz per year, and incorporating a gold price of A$2,750 – has a Net Present Value (8% discount rate) of $442 million 5. Three open-pit deposits at Mandilla were included in the Scoping Study – Theia, Hestia and Eos. No contribution was included from the Iris deposit. Similarly, the Scoping Study did not include any contribution from Astral’s nearby Feysville Project, which currently hosts a 196koz MRE 6. 2 Mandilla JORC 2012 Mineral Resource Estimate: 21Mt at 1.1g/t Au for 694koz Indicated Mineral Resources and 17Mt at 1.1g/t Au for 571koz Inferred Mineral Resources. See ASX Announcement 20 July 2023. 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.” 5 ASX Announcement 21 September 2023 “Mandilla Gold Project – Kalgoorlie, WA. Positive Scoping Study” 6 Feysville JORC 2012 Mineral Resource Estimate: 4Mt at 1.3g/t Au for 144koz Indicated Mineral Resources and 1Mt at 1.1g/t Au for 53koz Inferred Mineral Resources (refer to ASX announcement dated 1 November 2024). astralresources.com.au ASX: AAR | 4 A map of Mandilla illustrating both the local area geology and mineral deposits is set out in Figure 2. Figure 2 – Map of Mandilla Gold Project identifying known deposits on local area geology. THEIA DIAMOND DRILL RESULTS The Theia Deposit hosts an MRE of 29Mt at 1.1g/t Au for 1.02Moz of contained gold. Of this, the higher confidence Indicated category accounts for 17Mt at 1.1g/t Au for 571koz of contained gold or approximately 56% of the MRE. Since the release of the July 2023 MRE, drilling at Theia has focused on in-filling the deposit, with several drill programs having been undertaken with the aim of increasing the drill density and, hence, MRE confidence levels. With a significant portion of the Theia Resource at depth at the southern end of the deposit classified in the lower confidence Inferred category, Astral completed a four-hole (1,762-metre) DD program to astralresources.com.au ASX: AAR | 5 achieve a 40 metre by 40 metre drill spacing at this location. The four drill holes were planned on the same orientation (150 azimuth) as much of the previous drilling in this location. A map showing the drill-hole collar locations on local area geology is presented in Figure 3. Figure 3 – Map of Theia illustrating drill collar locations of recent and historical drilling on local area geology. Assay results have now been received for the final two holes (850 metres) of the four-hole (1,762metre) DD program (results for the first two holes were reported to the ASX on 20 January 2025 7). DD hole MDRCD917 was designed as a 40-metre step-out from MDRCD644, which previously returned 283 gram-metres 8 of gold mineralisation over the length of the hole. 7 ASX Announcement 20 January 2025 “Wide Zones of Strong Gold Mineralisation at Theia Deeps.” 8 ASX Announcement 21 September 2022 “Mandilla’s Theia Deposit Extended at Depth” astralresources.com.au ASX: AAR | 6 Drill-hole MDRCD917 has returned an aggregate 154 gram-metres of gold mineralisation over the length of the hole with best results including: • 72.2 metres at 1.15g/t Au from 326 metres including 0.3 metres at 34.9g/t Au from 328.35 metres and 0.62 metres at 25.6g/t Au from 396 metres; • 2.2 metres at 15.4g/t Au from 317.6 metres including 1.05 metres at 29.9g/t Au from 317.62 metres; • 17.4 metres at 0.44g/t Au from 266 metres; • 16.5 metres at 0.47g/t Au from 244 metres; • 13.2 metres at 0.40g/t Au from 219 metres; and • 22 metres at 0.57g/t Au from 105 metres. DD-hole MDRCD918 was designed as an in-fill hole to reduce line spacing on section between holes MDRCD644 and MDRCD645 to 40 metres. Drill-hole MDRCD645 previously returned 111 grammetres9 of gold mineralisation over the length of the hole. Drill-hole MDRCD918 has returned an aggregate 1,079 gram-metres of gold mineralisation over the length of the hole, with best results including: • 1.0 metre at 223.3g/t Au from 15 metres; • 1.0 metre at 12.2g/t Au from 149 metres; • 9.6 metres at 27.6g/t Au from 194 metres including 0.95 metres at 227.6g/t Au from 197.25 metres and 1 metre at 33.1g/t Au from 199 metres; • 2.4 metres at 169.1g/t Au from 225 metres; • 2.0 metres at 4.15/t Au from 270 metres; • 3.6 metres at 7.14g/t Au from 303 metres including 0.4 metres at 54.5g/t Au from 303.35 metres; • 12 metres at 0.52g/t Au from 333 metres; and • 24.9 metres at 4.14g/t Au from 362 metres including 0.7 metres at 11.3g/t Au from 362.3 metres, 0.3 metres at 11.3g/t Au from 364.55 metres, 1 metre at 60.6g/t Au from 375 metres and 0.3 metres at 24.6g/t Au from 380.7 metres. A longitudinal projection that illustrates drill-holes MDRCD644 – 645 and MDRCD917 – 918 is set out in Figure 4 (see Figure 3 for section location). 9 ASX Announcement 3 November 2023 “Mandilla Delivers More Wide, High-Grade Gold Intercepts Ahead of MRE Update” astralresources.com.au ASX: AAR | 7 Figure 4 – Longitudinal projection through Theia illustrating drill trace, assay results and geological interpretation (see Figure 3 for section location). The intersections appear to conform well to the current MRE, which Astral anticipates will increase the higher confidence Indicated category when the MRE is updated during the March Quarter. A spectacular high-grade hit in hole MDRCD918 (2.42m at 169.05 g/t Au from 224.58m) is interpreted to be related to a high-grade mineralised zone first identified in diamond hole MDRCD230 (0.95m at 45.5g/t Au from 238.6m). This structure appears to be sub-parallel to a regional structure, the Karrimindie Shear, which is interpreted as a primary control on gold mineralisation at Mandilla. It is encouraging that recent drilling has further delineated this high-grade structure, which could provide a substantial source of high-grade material in the mining of the Theia Deposit. FEYSVILLE GOLD PROJECT The Feysville Gold Project is located within the north-north-west trending Norseman – Wiluna Greenstone Belt, within the Kambalda Domain of the Archean Yilgarn Craton, approximately 14km south of the KCGM Super Pit in Kalgoorlie. Significant gold and nickel mineralisation occurs throughout the belt, including world-class deposits such as the Golden Mile Super Pit in Kalgoorlie owned by Northern Star Resources Limited (ASX: NST) astralresources.com.au ASX: AAR | 8 and the St Ives Gold Mine, south of Kambalda, owned by Gold Fields Limited. The area also hosts the substantial Beta Hunt Gold Mine, owned by Westgold Resources Limited (ASX: WGX). Feysville hosts an MRE of 5Mt at 1.2g/t Au for 196koz11 of contained gold at the Kamperman, Think Big and Rogan Josh deposits, providing a strong foundation for the project to become a source of satellite ore feed for a future operation based on Astral’s flagship Mandilla Gold Project. Locally, Feysville has been interpreted to contain upthrust ultramafics, emplaced within a sequence of volcanic sediments (the Black Flag sediment group), granitic intrusions, mafic basalts, gabbro and andesite. A map of the Feysville Gold Project showing tenements and deposits/prospects on local area geology is set out in Figure 5. Figure 5 – Map of Feysville Gold Project identifying known deposits on local area geology. astralresources.com.au ASX: AAR | 9 KAMPERMAN RC DRILL RESULTS During the December Quarter of 2024, a 31-hole (3,834-metre) in-fill and extensional drill program was completed at the Kamperman Deposit. The original drill proposal included an in-fill line to reduce line spacing at the southern end of the southern Kamperman lode to 20 metres. This line of drilling was not completed as part of that program. Drill-holes FRC392 – FRC394 were drilled prior to Christmas to complete this program. As expected, mineralisation at the tail end of this lode narrows and weakens and appears to terminate 20 metres further south. Best results include 6 metres at 1.05g/t Au from 114 metres in FRC394. A map showing the drill-hole collar locations on local area geology is presented in Figure 6. Figure 6 – Map of Kamperman illustrating drill collar locations of recent and historical drilling on local area geology. astralresources.com.au ASX: AAR | 10 EXPLORATION UPDATE Diamond drilling has commenced at Feysville, with two programs planned: • A 3-hole (350-metre) program at Kamperman is currently underway, which is designed to increase the understanding of controls associated with high-grade mineralisation and to provide sample material for metallurgical testwork; and • A 17-hole (1,610-metre) geotechnical drill program incorporating the Kamperman, Rogan Josh and Think Big deposits. Air-core drilling has also commenced at Feysville with approximately six line-kilometres of regional drilling to be completed. This will consist of six lines of drilling (4.3 line-kilometres) designed to test the Central Feysville Anticline and four lines (1.7 line-kilometres) designed to test several structural targets on Feysville’s southern tenements (refer Figure 5). . Once the regional AC program has been completed, an RC rig is scheduled to return to Feysville to complete the following: • A 15-hole (2,100-metre) in-fill and extensional drilling program to the north of the Kamperman deposit; and • A 15-hole (2,100-metre) regional drilling program, following up on the significant gold intercepts from the regional AC program completed during the June 2024 Quarter. A number of these significant AC intercepts have previously highlighted the potential for these areas to emerge as a Kamperman analogue. Cube Consulting has commenced work to update the Mandilla MRE, which is expected to be completed in the March Quarter 2025. astralresources.com.au ASX: AAR | 11 CONSOLIDATED MINERAL RESOURCE ESTIMATE The Group’s consolidated JORC 2012 Mineral Resource Estimate as at the date of this announcement is detailed in the table below.
