Announcement PDF ASX Announcement 30 August 2023 HIGH-GRADE AIR-CORE RESULTS OF UP TO 28.0g/t HIGHLIGHT FURTHER GROWTH POTENTIAL AT MANDILLA GOLD PROJECT Assay results from air-core drilling completed in May 2023 demonstrate the potential to continue extending the Eos palaeochannel deposit to the south-east, highlighting the opportunity to grow the existing shallow 41koz Mineral Resource with further drilling. HIGHLIGHTS • Significant assay results returned from a limited air-core (AC) drill program of 33 drill-holes for 2,132 metres completed at Eos, at the southern end of the 1.27Moz Mandilla Gold Project in WA, include: • 8 metres at 9.58g/t Au from 49 metres including 3 metres at 18.93g/t Au from 49 metres (which included a high-grade 1 metre interval of 28.02g/t Au) and 1 metre at 12.1g/t Au from 54 metres in MDAC613 • 10 metres at 5.05g/t Au from 45 metres including 3 metres at 11.81g/t Au from 49 metres in MDAC623 • 4 metres at 4.55g/t Au from 46 metres in MDAC622 • 9 metres at 2.04g/t Au from 44 metres in MDAC624 • 2 metres at 2.59g/t Au from 61 metres in MDAC598 • AC drilling has extended the extent of known mineralisation at the shallow Eos palaeochannel towards the south-east, with further AC drilling to be completed in the coming months. • A Reverse Circulation (RC) drilling program has recently been completed at the Feysville Project near Kalgoorlie, with assays pending. • In-fill RC drilling is currently underway to the south-east of the Theia deposit at Mandilla. • Diamond drilling (DD) is planned to commence at Theia in September 2023. • A structural review of the Theia deposit is expected to be completed in September 2023. • Scoping Study activities are well progressed with completion targeted for completion later this quarter. ASX Announcement 30 August 2023 Astral Resources’ Managing Director Marc Ducler said: “Despite the modest scale of the air-core program, it has delivered exceptional high-grade assay results from drilling designed to test the south-eastern extent of the Eos palaeochannel, which already hosts a Mineral Resource Estimate (MRE) of 0.8Mt at 1.6g/t Au for 41koz of contained gold 1. “The drilling has not only confirmed that the palaeochannel remains open to the southeast but it has also returned some of the highest grade assays obtained at Eos so far. “MDAC613 returned the best result to date at Eos with 8 metres at 9.58g/t Au from 49 metres. This includes a very high-grade component of 3 metres at 18.93g/t Au from 49 metres. “When combined with the results from MDAC623 – 10 metres at 5.05g/t Au from 45 metres (including 3 metres at 11.81g/t Au from 49 metres) and MDAC276 – 6 metres at 7.41g/t Au from 49 metres (including 3 metres at 10.86g/t Au from 49 metres), these results define a high-grade central channel which extends for over 90 metres and remains open to the south-east. This is a very pleasing result which clearly demonstrates the potential for further resource growth at Mandilla. “RC drilling re-commenced in early August, with a program recently completed at Feysville and an in-fill program at Theia, Mandilla currently underway. “Diamond drilling is expected to resume at Theia in mid-September. “The Scoping Study is well advanced with only limited workstreams and report compilation still outstanding. We are looking forward to delivering the Scoping Study to the market later this quarter.” - Mandilla JORC 2012 Mineral Resource Estimate: 21Mt at 1.1g/t Au for 694koz Indicated and 17Mt at 1.1g/t Au for 571koz Inferred. See ASX Announcement 20 July 2023. 1 ASX Announcement 30 August 2023 Astral Resources NL (ASX: AAR) (Astral or the Company) is pleased to report assay results from recently completed air-core (AC) drilling at the 100%-owned Mandilla Gold Project (Mandilla), located approximately 70km south of Kalgoorlie in Western Australia (Figure 1). Figure 1 – Mandilla and Feysville Gold Projects location map. MANDILLA GOLD PROJECT The Mandilla Gold Project includes the Theia, Iris, Eos and Hestia deposits. In July 2023, Astral announced an updated Mineral Resource Estimate (MRE) of 37Mt at 1.1 g/t Au for 1.27Moz of contained gold 2 for the Mandilla Gold Project. 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 (Figure 2). 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 now has a mineralised footprint extending over a strike length of more than 1.6km. 2 - Mandilla JORC 2012 Mineral Resource Estimate: 21Mt at 1.1g/t Au for 694koz Indicated and 17Mt at 1.1g/t Au for 571koz Inferred. See ASX Announcement 20 July 2023. ASX Announcement 30 August 2023 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. 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 the primary mineralisation at Theia and Iris, remains open both down-dip and along strike. Metallurgical testing undertaken on the Theia Deposit has demonstrated high gravity recoverable gold, fast leach kinetics and exceptional overall gold recoveries with low reagent consumptions and coarse grinding 3. Mandilla is covered by existing Mining Leases which are not subject to any third-party royalties other than the standard WA Government gold royalty. 3 ASX Announcement 6 June 2022 “Outstanding metallurgical test-work results continue to de-risk Mandilla.” ASX Announcement 30 August 2023 Figure 2 – Mandilla local area geology and deposits (including significant intercepts). EXPLORATION UPDATE Following conclusion of the RC and DD programs in May 2023, an AC rig was mobilised to the Eos palaeochannel deposit at Mandilla to in-fill drill-lines from a wide spaced regional AC program that ASX Announcement 30 August 2023 was reported in February 2022 and which identified a possible extension to the palaeochannel mineralisation. This announcement reports assay results for the 33 AC holes for 2,132 metres that were completed as part of this program. The locations of the drill holes reported in this announcement are shown in Figure 3. Figure 3 – Drill collar and section location on local area geology for Eos drilling. ASX Announcement 30 August 2023 EOS AC DRILL RESULTS The recently completed air-core drilling program has continued to extend and delineate the extent of known mineralisation at the Eos palaeochannel to the south-east, with the mineralisation remaining open in this direction. Best assay results include: • • • • • 8 metres at 9.58g/t Au from 49 metres including 3 metres at 18.93g/t Au from 49 metres and 1 metre at 12.1g/t Au from 54 metres in MDAC613 10 metres at 5.05g/t Au from 45 metres including 3 metres at 11.81g/t Au from 49 metres in MDAC623 4 metres at 4.55g/t Au from 46 metres in MDAC622 9 metres at 2.04g/t Au from 44 metres in MDAC624 2 metres at 2.59g/t Au from 61 metres in MDAC598 MDAC613 returned the best results to date at Eos and, when combined with the results from MDAC623 and the previously drilled MDAC276, define a high-grade central channel to the palaeochannel mineralisation of 3 metres at 18.93g/t Au (MDAC613), 3 metres at 11.81g/t Au (MDAC623) and 3 metres at 10.86g/t Au (MDAC276) all at 49 metres down-hole. This high-grade central channel currently extends for approximately 90 metres and remains open to the south-east. In addition to palaeochannel style mineralisation, in-situ gold mineralisation was encountered in some of the holes, interpreted to be associated with a splay from the Theia hosting ‘Karramindie shear’ which follows the granite/sediment contact to the south-east and is the interpreted source of the Iris deposit. Further drilling will be planned to follow up on these encouraging results. ASX Announcement 30 August 2023 Figure 4 – Eos longitudinal projection (refer Figure 3 for section location) ASX Announcement 30 August 2023 FEYSVILLE REVERSE CIRCULATION DRILLING UPDATE A modest RC drill program of 23 RC holes for 3,202 metres has been completed at Feysville. A total of 11 holes were drilled at Ethereal, four holes at Hyperno and eight holes at Kamperman. All three prospects returned positive results in the initial drill program that was completed in January 2023. Assay results are pending. THEIA IN-FILL REVERSE CIRCULATION DRILLING UPDATE RC drilling is currently underway to complete the Theia in-fill drilling program that was suspended in May 2023. This program will consist of 23 holes for 3,720 metres. FUTURE WORK PROGRAM Following completion of the RC drill program, a DD rig will be mobilised to Mandilla to continue testing the central portion of the Theia deposit with the objective of extending the known extent of mineralisation both on the flanks and at depth. An AC rig will also be mobilised in the December Quarter to complete the regional program to the south-east of Eos. The structural review of previously drilled DD core at Theia remains on track for completion in the September Quarter. The Scoping Study remains on track to be reported later this quarter.

Several programs of RC percussion, diamond and air core drilling were Acknowledgment and appraisal of completed in the area between 1988-1999 by Western Mining Corporation exploration by other parties. (WMC). In early 1988 a significant soil anomaly was delineated, which was tested late 1988 early 1989 with a series of 4 percussion traverses and diamond drilling. Gold mineralisation was intersected in thin quartz veins within a shallowly dipping shear zone. 1989-90- limited exploration undertaken with geological mapping and 3 diamond holes completed. 1990-91- 20 RC holes and 26 AC were drilled to follow up a ground magnetic survey and soil anomaly. 1991-94 - no gold exploration undertaken 1994-95 – extensive AC programme to investigate gold dispersion. A WNW trending CS defined lineament appears to offset the Mandilla granite contact and surrounding sediments, Shallow patchy supergene (20-25m) mineralisation was identified, which coincides with the gold soil anomaly During 1995- 96 - Three AC traverses 400m apart and 920m in length were drilled 500m south of the Mandilla soil anomaly targeting the sheared granite felsic sediment contact. 1996-97 - A 69 hole AC program to the east of the anomaly was completed but proved to be ineffective due to thin regolith cover in the area.
