Announcement PDF Talisman Mining | Suite 1, Ground Floor, 33 Colin St, West Perth 6005 ABN 71079 536 495 talismanmining.com.au ASX:TLM 28April2026 ASX Announcement 1 Tomingley Gold Project – Geological Setting and Mineralisation. Chalmers, Ransted, Kairatis and Meates 2015. 2 Tomingley Gold Operations – Mineral Resource Statement 30 June 2025 1 Further air-core drill results highlight gold and copper-gold potential at East Peak Hill, NSW Maiden drilling returns anomalous zones and strong indicators of potential for both large-scale vein-style gold and porphyry-style copper-gold mineralisation Highlights: Macquarie Projects, NSW East Peak Hill • Final assay results received from the Company’s maiden 5,546m, 95-hole air-core drilling (AC) program completed across seven lines at the East Peak Hill (EPH) Prospect in NSW. • EPH sits adjacent to the Tomingley and Peak Hill gold district (1.36Moz at 2.2g/t Au), which is currently being mined by Alkane Resources (ASX: ALK)1 2 . • The AC drilling tested a 4.5km-long trend of interpreted intrusive rocks within the highly prospective Junee-Narromine Volcanic Belt – host to several major gold and copper-gold deposits. • Results from Line 2 indicate both anomalous gold and promising pathfinder minerals on the eastern contact of this belt, with a similar structural position and geochemical signature to the mineralisation at the nearby Tomingley Operations. • Results further south on Line 7 indicate a broad zone of anomalous copper, cobalt and gold with promising pathfinder minerals adjacent to a large de-magnetised geophysical target. • A follow up AC drilling program is scheduled to commence in mid-May. Further to its ASX announcement of 7 April 2026, Talisman Mining (ASX: TLM, ‘Talisman’ or ‘the Company’) is pleased to report remaining assay results from the maiden 95-hole, 5,546m air-core (AC) drilling program (Figure 1 and Figure 2) completed across seven drill lines at its East Peak Hill Project, located approximately 70km south-west of Dubbo in NSW (Figure 2). East Peak Hill Gold Project (EL 9395) – Background The East Peak Hill Gold Project contains an interpreted andesitic intrusion outlined by anomalous magnetic features interpreted from detailed magnetic imagery, as shown in Figure 4. In 2025, Talisman commenced a first-pass Auger sampling program to test for presence of pathfinder elements known to be linked to the targeted gold and copper-gold mineralisation. At the nearby Tomingley Project, owned by Alkane Resources (1.36Moz at 2.2g/t gold)1,2 , pathfinder elements are used extensively in exploration to highlight prospective locations for mineralisation. The Talisman Auger drill program was partially successful with many of the Auger holes failing to reach the basement target due to deeper-than-expected barren transported cover. Those Auger holes that did reach the top of the underlying basement recorded anomalous pathfinder minerals – arsenic, antimony, bismuth, copper and molybdenum – associated with the targeted gold and copper-gold mineralisation on both the western side and eastern side of the interpreted intrusive rocks. 4August2024 ASX Announcement The recently completed AC drilling program was designed to test the area of the interpreted mineralised target zone with broad, regional-scale, 400m and 800m line spacing, as an initial test of the target prospectivity. Figure 1. Wallis Drilling AC drilling rig operating at the East Peak Hill Prospect. AC Program Details The recently completed air-core program (AC) consisted of seven east-west lines of AC drill fences to test the postulated north-south magnetic features, covering a strike length of ~4.5km. These features contain a number of north-northeast trending structures (Figure 4), which are seen as key to the emplacement of gold mineralisation in the district. This work was completed with Wallis Drilling’s Mantis100 rig, shown in Figure 1. The key specifications of the AC drilling program are summarised below: - E-W drill grid (orthogonal to stratigraphy and interpreted structure/mineralisation). - Holes drilled to blade refusal (estimated 50m-80m depth). - Holes inclined at 60 degrees, drilled towards 270o (grid west). - Nominal 80m x 800m spaced drilling initially, with potential to in-fill to 400m spacing as results and geology dictate, as shown on Figure 4. - 3m composite samples with 25g Aqua Regia for gold, copper and a range of multi-elements. - Bottom-of-hole samples with comprehensive multi-element assays. - Barren surface cover was intersected from surface to approximately 10m to 30m down-hole. 4August2024 ASX Announcement Figure 2. Regional geology plan of the Junee-Narromine Volcanic Belt illustrating the gold and copper-gold deposits of the region. Talisman tenure in the belt consists of three EL’s. The East Peak Hill Project is located on EL 9395, approximately 10km south-east of the Tomingley Gold Operation.1 4August2024 ASX Announcement AC Program Results and Interpretation Assays have now been returned for all seven lines of AC drilling (Lines 1 to 7, holes EPAC0001 to EPAC0095). See Figure 4. The northern four lines tested de-magnetised positions that sit adjacent to the interpreted, strongly magnetic Andesite intrusions (these zones are shown in red in the central part of Figure 4). Line 2 tested the interpreted position of the Mingelo Volcanics/Cotton Formation contact in the east and intersected a zone of altered Volcaniclastic rocks with elevated gold, arsenic and antimony values in three consecutive holes EPAC0001 to EPAC0003. Maximumgoldvaluesinthiszonewere3mat1.75g/tAufrom33mwithina9mwideintersectionaveraging0.67g/t Au in EPAC0003. Within the northern lines of AC drilling, Line 3 and Line 4 were unable to test the prospective Mingelo Volcanics/ Cotton Formation contact as planned due to temporary access issues requested by the landowner. These lines will be extended to test this prospective position in the planned follow-up program, which is shown in Figure 4, scheduled to commence in mid-May. Line 5 to Line 7 tested demagnetised zones adjacent to interpreted andesitic intrusions in the southern half of the broad targeted Volcaniclastic horizon. Line 7 intersected a horizontal zone of elevated copper, cobalt, zinc, gold, silver, arsenic and antimony mineralisation immediately below the base of transported cover. This mineralisation sits within strongly weathered saprolitic clays above a weathered andesitic intrusion, illustrating carbonate veined and hematite altered Volcaniclastic and Andesitic Porphyry at the base of a number of the mineralised holes. See Figure 3. The anomalous mineralisation on Line 7 is interpreted as a horizontal blanket of supergene mineralisation located distal from the source of the metals, which warrants immediate follow -up. An additional three lines of AC drilling are planned to test a large, oblong shaped de-magnetised geophysical feature located immediately south of Line 7. These three lines of drilling are designed to test for further supergene and oxidised mineralisation above a potential copper-gold mineralised porphyry intrusion. 4August2024 ASX Announcement Figure 3. AC drill chips/cores from bottom-of-hole (78m down-hole) in EPAC0083 on Line 7. Bottom-of-hole samples along line 7 from EPAC0082 to EPAC0087 show hematite-altered and carbonate veined Mingelo Volcanic rocks. 4August2024 ASX Announcement • Figure 4. AC drilling program at East Peak Hill over regional magnetics and structural interpretation. Magnetic highs are generally associated with Andesitic sills within the Mingelo Volcanic sequence. Anomalous pathfinder and gold mineralisation in Line 2 is associated with Mingelo Volcaniclastic/Cotton Formation sediments contact on the eastern side of the drill line. 4August2024 ASX Announcement Line 7 On Line 7, six consecutive drill holes EPAC0082 to EPAC0087 intersected a zone of significant elevated copper, cobalt and zinc mineralisation with sporadic gold, arsenic and antimony anomalism spanning a width of approximately 350m. The mineralisation is associated with a hematite and carbonate altered volcaniclastic and andesitic intrusive rocks. See Figure 5. This style of alteration, metal anomalism and structural position is interpreted to be analogous to porphyry copper style mineralisation. The nearest porphyry copper-gold deposit is located approximately 20km along strike to the south of the current drilling, at the Buryan prospect (see Figure 2), owned by Magmatic Resources (ASX:MAG). See Magmatic ASX announcement 21 February 2019. Buryan contains a number of strong copper-gold intersections including • 135m at 0.29% Cu and 0.17ppm Au from 254m and • 40m at 0.32% Cu and 0.1g/t Au from 171m Buryan sits adjacent to a large, demagnetised zone within the hosted volcaniclastic rocks, along strike from East Peak Hill. Figure 5. AC drilling at East Peak Hill cross section Line 7. See Figure 4 for location. Assay results show a broad zone of anomalous in Cu-Co-Zn-Au-As-Sb in weathered Volcaniclastics and andesitic porphyry in holes EPAC0082 and EPAC0087 spanning approximately 350m. Line 2 On Line 2, three consecutive drill holes EPAC0001 to EPAC0003 intersected a zone of sericite-carbonate alteration of Volcaniclastic rocks with significant elevated gold, silver, arsenic and antimony anomalism. This style of alteration, metal anomalism and structural position is analogous to the Tomingley-style mineralisation, located approximately 10km north-west of the current drilling. 4August2024 ASX Announcement These holes sit adjacent to the contact between the interpreted Mingelo Volcanic rocks containing a number of andesitic intrusions to the west and the Cotton Formation sediments to the east intersected in EPAC0038 and EPAC0039. See Figure 6. Significant intersections are summarised in Table 1 and illustrated in Figure 6. Figure 6. AC drilling at East Peak Hill cross section Line 2. See Figure 3 for location.

Management Comment Talisman’s Managing Director, Andrew Munckton, said: “The recently completed air-core drilling program at East Peak Hill was designed to target a series of interpreted andesitic intrusions and the highly prospective volcaniclastic/sediment contact in the east, where limited soil geochemistry has defined anomalous pathfinder minerals at the edges of the interpreted intrusive bodies. “These intrusions – and their sheared and faulted contacts with the surrounding rocks – host a number of significant gold deposits at the nearby Tomingley Gold Mine, operated by Alkane Resources. “The broad 400m and 800m spaced lines of AC drilling have provided an initial test of the target, which is interpreted as being analogous to the Tomingley structural position and nearby porphyry copper-gold mineralisation style. “Line 2 of the initial seven drilled has returned anomalous assay results within the oxidised portion of the geological profile. The intersections recorded in holes EPAC0001 and EPAC0003 show ore grade gold mineralisation located in the targeted structural position coincident with an important geological contact. These results demonstrate that this zone is a fertile location for orogenic gold mineralisation. “In addition, a broad zone of anomalous copper-cobalt-zinc with attendant gold-silver-arsenic-antimony mineralisation has been located within line 7. This metal anomalism sits within a horizontal zone of enrichment within the weathered zone above the altered andesitic intrusive and volcaniclastic rocks in this area. “Line 7 was drilled immediately north of a large geophysical feature where the andesite and volcaniclastics have apparently been demagnetised, potentially by a later secondary porphyritic intrusion. “The follow-up AC program planned to commence in mid-May is designed to further evaluate these two exciting targets for vein-style orogenic gold mineralisation and porphyry-style copper-gold mineralisation, both found extensively throughout the district.” –– Ends –– For further information, please contact: Andrew Munckton - Managing Director +61 4 3563 5598 Nicholas Read (Media inquiries) +61 4199 29046 This release has been authorised by the Board of Talisman Mining Limited. 4August2024 ASX Announcement Hole ID Easting Northing RL Dip Azi EoH Depth EPAC0001 619450 6378650 302 -60 270 61 EPAC0002 619390 6378647 303 -60 270 61 EPAC0003 619335 6378658 304 -60 270 52 EPAC0004 619280 6378660 305 -60 270 54 EPAC0005 619224 6378661 305 -60 270 64 EPAC0006 619159 6378665 300 -60 270 57 EPAC0007 619096 6378664 298 -60 270 51 EPAC0008 619046 6378664 299 -60 270 45 EPAC0009 619005 6378668 295 -60 270 54 EPAC0010 618953 6378670 295 -60 270 54 EPAC0011 618899 6378674 294 -60 270 69 EPAC0012 618847 6378680 295 -60 270 58 EPAC0013 618772 6378683 293 -60 270 42 EPAC0014 618733 6378683 292 -60 270 31 EPAC0015 618708 6378685 294 -60 270 40 EPAC0016 618660 6378677 294 -60 270 30 EPAC0017 618632 6378690 292 -60 270 34 EPAC0018 618600 6378690 295 -60 270 24 EPAC0019 618574 6378692 295 -60 270 28 EPAC0020 618546 6378694 295 -60 270 39 EPAC0021 618509 6378695 295 -60 270 35 EPAC0022 618435 6378702 295 -60 270 69 EPAC0023 618374 6378707 295 -60 270 64 EPAC0024 618309 6378703 295 -60 270 78 EPAC0025 618243 6378715 296 -60 270 57 EPAC0026 618180 6378711 298 -60 270 81 EPAC0027 618133 6378715 298 -60 270 72 EPAC0028 618733 6379029 295 -60 270 27 EPAC0029 618702 6379029 295 -60 270 36 EPAC0030 618668 6379034 295 -60 270 45 EPAC0031 618629 6379032 295 -60 270 51 EPAC0032 618529 6379023 295 -60 270 63 EPAC0033 618464 6379029 295 -60 270 70 EPAC0034 618397 6379029 295 -60 270 63 4August2024 ASX Announcement EPAC0035 618340 6379031 295 -60 270 69 EPAC0036 618278 6379033 297 -60 270 75 EPAC0037 618208 6379030 297 -60 270 66 EPAC0038 619497 6378649 305 -60 270 72 EPAC0039 619563 6378648 305 -60 270 75 EPAC0040 619261 6378199 305 -60 270 72 EPAC0041 619179 6378204 304 -60 270 64 EPAC0042 619110 6378197 300 -60 270 63 EPAC0043 619037 6378196 297 -60 270 72 EPAC0044 619204 6377597 305 -60 270 64 EPAC0045 619112 6377624 305 -60 270 63 EPAC0046 619047 6377657 305 -60 270 65 EPAC0047 618942 6377676 300 -60 270 45 EPAC0048 618781 6377598 300 -60 270 54 EPAC0049 618718 6377602 300 -60 270 44 EPAC0050 618588 6377595 300 -60 270 43 EPAC0051 618529 6377597 300 -60 270 58 EPAC0052 618396 6377601 305 -60 270 28 EPAC0053 618351 6377603 305 -60 270 13 EPAC0054 618300 6377601 305 -60 270 9 EPAC0055 618249 6377605 305 -60 270 8 EPAC0056 618203 6377602 305 -60 270 26 EPAC0057 618153 6377602 304 -60 270 39 EPAC0058 618104 6377602 298 -60 270 46 EPAC0059 619920 6376143 323 -60 270 63 EPAC0060 619866 6376142 319 -60 270 57 EPAC0061 619797 6376172 318 -60 270 61 EPAC0062 619758 6376193 318 -60 270 53 EPAC0063 619625 6376150 314 -60 270 69 EPAC0064 619566 6376148 314 -60 270 70 EPAC0065 619490 6376150 308 -60 270 86 EPAC0066 619401 6376152 308 -60 270 67 EPAC0067 619331 6376151 308 -60 270 81 EPAC0068 619253 6376150 308 -60 270 69 EPAC0069 619851 6375454 323 -60 270 60 EPAC0070 619790 6375448 322 -60 270 69 EPAC0071 619717 6375454 318 -60 270 69 4August2024 ASX Announcement EPAC0072 619649 6375453 316 -60 270 69 EPAC0073 619576 6375458 316 -60 270 69 EPAC0074 619511 6375458 315 -60 270 51 EPAC0075 619461 6375462 315 -60 270 45 EPAC0076 619396 6375458 315 -60 270 75 EPAC0077 619320 6375464 313 -60 270 78 EPAC0078 619248 6375466 310 -60 270 58 EPAC0079 619169 6375464 310 -60 270 67 EPAC0080 619915 6375454 325 -60 270 63 EPAC0081 619980 6375454 325 -60 270 72 EPAC0082 619771 6374629 325 -60 270 72 EPAC0083 619702 6374633 324 -60 270 78 EPAC0084 619630 6374632 323 -60 270 64 EPAC0085 619572 6374627 320 -60 270 58 EPAC0086 619520 6374628 320 -60 270 70 EPAC0087 619460 6374630 320 -60 270 61 EPAC0088 619401 6374632 320 -60 270 87 EPAC0089 619324 6374632 318 -60 270 81 EPAC0090 619246 6374634 317 -60 270 84 EPAC0091 619163 6374632 315 -60 270 74 EPAC0092 619086 6374632 315 -60 270 68 EPAC0093 619013 6374630 315 -60 270 81 EPAC0094 619831 6374632 325 -60 270 71 EPAC0095 619886 6374616 325 -60 270 84 Table 3. East Peak Hill AC drilling hole Summary. About Talisman Mining Talisman Mining Limited (ASX: TLM) is an Australian mineral development and exploration company. The Company’s aim is to maximise shareholder value through exploration, discovery and development of complementary opportunities in base and precious metals. Talisman has secured tenements in the Cobar/Mineral Hill region in Central NSW through the grant of its own Exploration Licenses. The Cobar/Mineral Hill region is a richly mineralised district that hosts several base and precious metal mines including the CSA, Tritton, and Hera/Nymagee mines. This region contains highly prospective geology that has produced many long-life, high-grade mineral discoveries. Talisman has identified several areas within its Lachlan Cu-Au Project tenements that show evidence of base and precious metals endowment which have had very little modern systematic exploration completed to date. Talisman also has a significant tenement holding in both the Molong and Junee-Narromine belts within the Macquarie Arc geological domain. The Macquarie Arc hosts several of Australia’s largest gold and copper-gold discoveries and operations including, Cadia Valley, North Parkes, Cowal and Tomingley.

These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. TLM Auger Drilling • Auger samples are collected as one or two metre interval from bottom of hole via a drill rig mounted Auger drill to obtain Top of Basement sample • The Top of Basement sample is sieved to 2mm to obtain a nominal 1.0kg sample which was collected in a pre- numbered sample bag. • Auger samples undergo routine pXRF analysis using an Olympus Vanta M-series to aid in logging and identifying zones of interest. • Sampling is controlled by Talisman protocols and QAQC procedures as per industry standard and a chain of custody maintained through transfer to ALS Laboratories in Adelaide, SA. • Auger samples were dried, crushed (where required), split and pulverised (total prep) to produce a master pulp. From this master pulp, a 0.25g sub sample was taken for multi- element analysis by four acid digest, with an ICP-MS finish. A 50g sub sample was also taken for fire assay for gold with ICP-AAS finish. TLM AC Drilling • AC samples are collected at three metre intervals via a drill rig mounted cyclone and static cone splitter set to a 12% split to produce a nominal 4-7kg sample which was collected in a pre-numbered sample bag. • AC samples undergo routine 3 metre composite pXRF analysis using an Olympus Vanta M-series to aid in logging and identifying zones of interest. • Sampling is controlled by Talisman protocols and QAQC procedures as per industry standard and a chain of custody maintained through transfer to ALS Laboratories in Adelaide, SA. • AC samples were dried, crushed (where required), split and pulverised (total prep) to produce a master pulp. From this master pulp, a 25g sub sample was taken for aqua regia gold and multi-elements. TLM MR/DD Drilling • TLM’s diamond core samples are HQ3 in diameter and are cut either in half or one-third longitudinally using an automated Almonte core saw. Core is held securely in boats during cutting to maintain sample integrity. Sample intervals ranged from 0.3 to 1.3m in length, with most samples aligned to 1m intervals or adjusted to honour geological contacts. • TLM diamond core sampling is controlled by protocols and 4August2024 ASX Announcement Criteria JORC Code explanation Commentary QAQC procedures as per industry standard and a chain of custody maintained through transfer to ALS Laboratories in Adelaide, SA. • TLM diamond samples are dried, crushed (where required), split and pulverised (total prep) to produce a master pulp. From this master pulp, a 0.25g sub sample was taken for multi-element analysis by four acid digest with an ICP-MS finish (ME-MS61) and analysis for Rare Earths (MS61L-REE). A 30g sub sample was also taken for fire assay for gold with ICP- AAS finish. Drilling techniques • Drill type (e.g. core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). TLM Auger drilling • AC drilling between 2m and 15m to obtain the top of Basement sample TLM AC drilling • AC drilling cited in this report was undertaken by Wallis Drilling Pty Ltd using a Mantis 100 drill rig. A truck-mounted compressor provided air where ground conditions warranted. • AC drilling was completed with a face sampling blade of nominal 120mm size. TLM MR/DD Drilling • Undertaken by DDH1 Drilling Pty LTD using a Multipurpose UDR1200 truck mounted rig. The core is orientated except where holes are vertical holes. Drill sample recovery • 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 TLM Auger Drilling • Auger drill sample recovery is generally moderate to high with sample recoveries and quality recorded in the database by the Auger operator. • Sample recoveries were monitored in real-time by the presence of Talisman personnel at the drill site. • No known relationship exists between recovery and grade. • No known bias exists. TLM AC Drilling • AC drill sample recovery is generally high. 4August2024 ASX Announcement Criteria JORC Code explanation Commentary preferential loss/gain of fine/coarse material. • Sample recoveries were monitored in real-time by the presence of Talisman personnel at the drill site. • No known relationship exists between recovery and grade. No known bias exists. TLM MR/ DD Drilling • Core recovery data is recorded for each run by measuring total length of core retrieved against the downhole interval drilled and stored in the database. TLM representatives continuously monitor core recovery and core presentation quality as drilling is conducted and issues or discrepancies are rectified promptly to maintain industry best standards. Logging • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. • The total length and percentage of the relevant intersections logged. TLM Auger Drilling • Auger drilling logging used to identify the appropriate Top of Basement horizon for sampling TLM AC Drilling • AC logging records lithology, mineralogy, mineralisation, alteration, structure, weathering, colour and other primary features of the rock samples and is considered to be representative across the intercepted geological units. • AC logging is both qualitative and quantitative depending on the field being logged. • All AC drill-holes are logged in full at 3m intervals to end of hole. • All AC chip trays at 3m intervals are collected, photographed and then stored onsite in TLM secure premises. • All information collected is entered directly into laptop computers or tablets, validated in the field, and then transferred to the database. The level of logging detail is considered appropriate for early-stage exploration. TLM MR/ DD Drilling • DD and MR logging are carried out on site once geology personnel retrieve core trays from the drill rig site. Core is collected from the rig daily. • DD/ MR logging records lithology, mineralogy, mineralisation, alteration, structure, weathering, colour and other primary features of the rock samples and is considered to be representative across the intercepted geological units. • All DD holes are logged in full to end of hole. • Drillhole collar coordinates, azimuth, dip, depth and sampling intervals are recorded. DD logging is to geological contacts. • MR/DD logging is both qualitative and quantitative depending on the field being logged.
