Positive Scoping Study” Astral Resources’ Managing Director Marc Ducler said: “This 26-hole drill program is arguably the most successful program completed to date at Kamperman. “These latest results confirm our geological interpretations with, pleasingly, a broad 30metre-wide zone of consistent +2g/t gold mineralisation defined across multiple sections in the southern zone at Kamperman. “Mineral Resource estimate work is now underway at Kamperman following receipt of these latest results, while the Rogan Josh and Think Big estimations are currently being finalised. “The focus is now turning to the Theia Deposit at the Mandilla Gold Project, with the first phase (6,000 metres) of in-fill RC drilling expected to get underway next week. “Following the completion of the Phase 1 program, Astral will return to Feysville following up the significant gold anomalies that were announced earlier this month in an area to the north-west of Kamperman.” Astral Resources NL (ASX: AAR) (Astral or the Company) is pleased to report assay results from a recently completed 26-hole/2,808 metre RC drilling program at the Kamperman Prospect, part of its 100%-owned Feysville Gold Project (Feysville), located approximately 14km south of Kalgoorlie in Western Australia (Figure 1). This announcement reports assay results for 23 holes of the 26-hole program. Assay results for the remaining three holes are pending.

ASTRAL RESOURCES NL ACN 009 159 077 astralresources.com.au ASX: AAR 2 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) 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 Karora Resources Inc. (TSX: KRR). Feysville hosts an MRE of 3Mt at 1.3g/t Au for 116koz of contained gold 2 at the Think Big deposit, providing a foundation for the project to potentially become a source of satellite ore feed to 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 identifying tenements and deposits/prospects on local area geology is set out in Figure 2. 2 - Feysville JORC 2012 Mineral Resource Estimate: 0.6Mt at 1.1g/t Au for 20.2koz Indicated Mineral Resources and 2.3Mt at 1.3g/t Au for 95.6koz Inferred Mineral Resources (refer to ASX Announcement dated 8 April 2019).

ASTRAL RESOURCES NL ACN 009 159 077 astralresources.com.au ASX: AAR 4 FEYSVILLE EXPLORATION UPDATE On 26 June 2024, Astral commenced a 26-hole RC drill program at Kamperman, where gold mineralisation has previously been delineated through RC drilling over a strike length of 450 metres. The primary purpose of this latest program was to reduce drill spacing to a 40 by 20 metre pattern. Several extensional holes, stepping out to the east on existing drilling lines, were also undertaken. The collar locations for the 26-hole drill program are set out in Figure 3. Figure 3 – Aerial image illustrating location of drill collars from latest RC program. ASTRAL RESOURCES NL ACN 009 159 077 astralresources.com.au ASX: AAR 5 KAMPERMAN REVERSE CIRCULATION DRILLING RESULTS Of the 26 holes drilled in the latest program, assay results have to date been received for 23 holes. In respect of these 23 holes, 14 were drilled as in-fill tests and nine were drilled as 20-metre up-dip steps within the current strike extent of Kamperman. Of the 23 holes, 20 returned significant gold mineralisation (greater than five gram-metres 3). Best results include: • • • • • • • • • • • • • 38 metres at 2.12g/t Au from 42 metres in FRC358; 34 metres at 2.24g/t Au from 33 metres in FRC353; 19 metres at 3.32g/t Au from 32 metres including 1 metre at 32.78g/t Au from 48 metres in FRC355; 18 metres at 1.51g/t Au from 28 metres in FRC343; 19 metres at 1.35g/t Au from 25 metres in FRC345; 8 metres at 2.40g/t Au from 20 metres in FRC344; 11 metres at 1.38g/t Au from 17 metres and 12 metres at 1.99g/t Au from 78 metres in FRC341; 3 metres at 5.45g/t Au from 64 metres including 1 metre at 15.15g/t Au from 65 metres in FRC359; 13 metres at 1.13g/t Au from 39 metres in FRC336; 8 metres at 1.64g/t Au from 35 metres in FRC351; 14 metres at 1.16g/t Au from 118 metres in FRC356; 11 metres at 1.24g/t Au from 39 metres in FRC348; and 4 metres at 3.09 g/t Au from 67 metres in FRC335; Towards the southern limit of known mineralisation at Kamperman, FRC355 was an in-fill hole planned to intersect a steeply west-dipping zone of gold mineralisation characterised by strong magnetite and sulphide mineralisation, coincident with a mafic unit. The hole returned 19 metres at 3.32g/t Au from 32 metres. To the west along the same drill line, hole FRC356 in-filled below the previously drilled FRC240, assaying 14 metres at 1.16g/t Au from 118 metres. A cross-section along this drill line is set out in Figure 4. 3 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 NL ACN 009 159 077 astralresources.com.au ASX: AAR 6 Figure 4 – Cross-section through Kamperman illustrating hole location, assay results and geological interpretation (refer Figure 3 for section location). As illustrated, at this location, a broad (typically 30-metres wide) zone of mineralisation, generally >2 g/t Au, is present, extending from a shallow depth, approximately 30 metres below surface, and representing the top-of-saprock horizon. With cross-sections through parallel drill lines to the south of Kamperman illustrating mineralised zones of broadly similar shape, this bodes well for the presence of a consistent zone of mineralisation from a shallow depth that will be easily accessible during mining. Towards the northern limit of known mineralisation at Kamperman, three holes were drilled in the latest program, FRC336 and, FRC337 as in-fill tests, and FRC335 as a 20 metre eastward up-dip test. Best assay results from these holes include: • • • 4 metres at 3.09g/t Au from 67m in FRC335; 13 metres at 1.13g/t Au from 39 metres in FRC336; and 9 metres at 0.74g/t Au from 89 metres in FRC337. A cross-section along this drill line is set out in Figure 5. ASTRAL RESOURCES NL ACN 009 159 077 astralresources.com.au ASX: AAR 7 Figure 5 – Cross-section through Kamperman illustrating hole location, assay results and geological interpretation (refer Figure 3 for section location). As illustrated, the gold mineralisation at this location to the north of Kamperman is quite different to that which is present to the south (illustrated above). Here, mineralisation is associated with quartz veining and pyrite hosted in feldspar porphyry, with high grade gold occurring on sheared contacts with ultramafic units, forming a moderate to shallow westdipping mineralised zone. That said, a flat-lying shallow zone of supergene related gold mineralisation is present in the north and seems consistent along the strike. The abrupt change in the nature of the gold mineralisation at Kamperman along strike from the north to the south suggests the presence of a fault which may offset the mineralisation. This is evidenced not only by this observed change in the nature of the gold mineralisation but also supported by way of borehole litho-geochemistry, regional geophysics and drill-hole logging data. Elsewhere, holes FRC338 and FRC344 were drilled as up-dip eastward step-outs along drill lines. Best assay results include: • • 8 metres at 2.40g/t Au from 20 metres in FRC344; and 16 metres at 0.77g/t Au from 14 metres in FRC338. Drill-holes FRC341, FRC343, FRC345, FRC353, FRC358 and FRC359 were drilled to test the continuity of a west-dipping ore body. ASTRAL RESOURCES NL ACN 009 159 077 astralresources.com.au ASX: AAR 8 Best assay result include: • • • • • • • 38 metres at 2.12g/t Au from 42 metres including 1 metre at 9.08g/t Au from 49 metres in FRC358; 34 metres at 2.24g/t Au from 33 metres in FRC353; 19 metres at 3.32g/t Au from 32 metres including 1 metre at 32.78g/t Au from 48 metres in FRC355; 18 metres at 1.51g/t Au from 28 metres in FRC343; 19 metres at 1.35g/t Au from 25 metres in FRC345; 12 metres at 1.99g/t Au from 78 metres in FRC341; and 3 metres at 5.45g/t Au from 64 metres including 1 metre at 15.15g/t Au from 65 metres in FRC359. The continuity of a west-dipping ore body was, indeed, confirmed through these results. In summary, the recent RC drill program at Kamperman has demonstrated the continuity of gold mineralisation and robustness of the current geological interpretations along 450 metres of strike at Kamperman. This augurs well for the forthcoming maiden MRE at Kamperman, work on which has already commenced, and which is due to be completed in the September Quarter. Notwithstanding the above, the Kamperman Prospect warrants further drilling, not only to better understand the controls to gold mineralisation along the known strike length but also to extend mineralisation where it remains open, being to the north, east and at depth. EXPLORATION UPDATE A 6,000 metre RC program is scheduled to begin at Theia on 5 August to advance the Mandilla Gold Project. This new program is the first of three phases of drilling totalling 14,000 metres which are designed to upgrade the Inferred Mineral Resources within the Stage 1 and Stage 2 Theia open pit designs envisaged in the Scoping Study completed in September 20231.

Down hole surveying of the drilling where documented has been undertaken using Eastman single shot cameras (in some of the historic drilling) and magnetic multi-shot tools and gyroscopic instrumentation. All Reverse Circulation (RC) drill samples were laid out in 1 metre increments and a representative 500 – 700 gram spear sample was collected from each pile and composited into a single sample every 4 metres. Average weight 2.5 – 3 kg sample. All Aircore samples were laid out in 1 metre increments and a representative 500 – 700 gram spear sample was collected from each pile and composited into a single sample every 4 metres. Average weight 2.5 – 3 kg sample. 1m samples were then collected from those composites assaying above 0.2g/t Au. Drilling techniques Drill sample recovery • Drill type (e.g. core, reverse circulation, openhole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, facesampling bit or other type, whether core is oriented and if so, by what method, etc). • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. All RC holes were drilled using face sampling hammer reverse circulation technique with a four-and-a-half inch bit. Definitive studies on RC recovery at Feysville have not been undertaken systematically, however the combined weight of the sample reject and the sample collected indicated recoveries in the high nineties percentage range. Poor recoveries are recorded in the relevant sample sheet. No assessment has been made of the relationship between recovery and grade. Except for the top of the hole, while collaring there is no evidence of excessive loss of material and at this stage no information is available regarding possible bias due to sample loss. RC: RC face-sample bits and dust suppression were used to minimise sample loss. Drilling airlifted the water column above the bottom of the hole to ensure dry sampling. RC samples are collected through a cyclone and cone splitter, the rejects deposited on the ground, and the samples for the lab collected to a total mass optimised for photon assay (2.5 to 4 kg). Poor recoveries are recorded in the relevant sample sheet.

Quality of assay data and laboratory tests ASTRAL RESOURCES NL ACN 009 159 077 • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. astralresources.com.au All chips and drill core were geologically logged by company geologists, using their current company logging scheme. The majority of holes (80%+) within the mineralised intervals have lithology information which has provided sufficient detail to enable reliable interpretation of wireframe. The logging is qualitative in nature, describing oxidation state, grain size, an assignment of lithology code and stratigraphy code by geological interval. RC: Logging of RC chips records lithology, mineralogy, mineralisation, weathering, colour and other features of the samples. All samples are wet-sieved and stored in a chip tray. RC holes were drilled and sampled. The samples are collected at 1m intervals via a cyclone and splitter system and logged geologically. A fourand-a-half inch RC hammer bit was used ensuring plus 20kg of sample collected per metre. Wet samples are noted on logs and sample sheets. Historical - The RC drill samples were laid out in one metre intervals. Spear samples were taken and composited for analysis as described above. Representative samples from each 1m interval were collected and retained as described above. No documentation of the sampling of RC chips is available for the Historical Exploration drilling. Recent RC drilling collects 1 metre RC drill samples that are channelled through a rotary cone-splitter, installed directly below a rig mounted cyclone, and an average 2-3 kg sample is collected in pre-numbered calico bags, and positioned on top of the rejects cone. Wet samples are noted on logs and sample sheets. Standard Western Australian sampling techniques applied. There has been no statistical work carried out at this stage. ALS assay standards, blanks and checks were inserted at regular intervals. Standards, company blanks and duplicates were inserted at 25 metre intervals. RC: 1 metre RC samples are split on the rig using a cone-splitter, mounted directly under the cyclone. Samples are collected to 2.5 to 4kg which is optimised for photon assay. Sample sizes are appropriate to the grain size of the material being sampled. Unable to comment on the appropriateness of sample sizes to grain size on historical data as no petrographic studies have been undertaken. Sample sizes are considered appropriate to give an indication of mineralisation given the particle size and the preference to keep the sample weight below a targeted 4kg mass which is the optimal weight to ensure representivity for photon assay. There has been no statistical work carried out at this stage. Photon Assay technique at ALS, Kalgoorlie. Samples submitted for analysis via Photon assay technique were dried, crushed to nominal 90% passing 3.15mm, rotary split and a nominal ~500g sub sample taken (AC/RC Chips method code CRU-32a & SPL32a, DD core method codes CRU-42a & SPL-32a) The ~500g sample is assayed for gold by PhotonAssay (method code AuPA01) along with quality control samples including certified reference materials, blanks and sample duplicates.
