Announcement PDF Talisman Mining | Suite 1, Ground Floor, 33 Colin St, West Perth 6005 ABN 71079 536 495 talismanmining.com.au ASX:TLM 7April2026 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 Initial air-core drill results confirm prospectivity of East Peak Hill gold prospect, NSW Maiden drilling returns anomalous zones and strong indicators of potential for a large-scale gold system adjacent to the Peak Hill and Tomingley gold districts Highlights: Macquarie Projects, NSW East Peak Hill • Maiden 5,546m, seven line, 95-hole air-core drilling (AC) program completed 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. • Initial 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. • Assay results are awaited for the remaining lines, for targets tested further south, which include interpreted porphyry and andesitic intrusion positions. Talisman Mining (ASX: TLM, ‘Talisman’ or ‘the Company’) is pleased to advise that it has completed a maiden 95- hole, seven line, 5,546m air-core (AC) drilling program (Figure 1 and Figure 2) at its East Peak Hill Project, located approximately 70km south-west of Dubbo in NSW (Figure 2), with the first batch of assay results received. 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 3. 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 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 gold mineralisation. The Talisman Auger drill program was partially successful. Many of the Auger holes did not 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 that are associated with the target 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 gold 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 approximately 4.5km. These features contain a number of north-northeast trending structures 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 & 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 3. - 3m composite samples with 25g Aqua Regia for gold 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 To date, assays have been returned for the three northern most lines of AC drilling (Lines 1 to 3, holes EPAC0001 to EPAC0043). See Figure 3. These lines tested de-magnetised positions that sit adjacent to the interpreted, strongly magnetic Andesite intrusions (those zones in red in the central part of Figure 3). In addition, Line 2 also tested the interpreted position of the Mingelo Volcanics/Cotton Formation contact in the east. 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. Line 3 and Line 4 will be extended east in the follow up phase of drilling. Figure 3. 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 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. 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 4. Significant intersections are summarised in Table 1 and illustrated in Figure 4. Figure 4. AC drilling at East Peak Hill cross section Line 2. See Figure 3 for location.

See ASX announcement 4 December 2025. Assay results from the two completed holes YRMRD0002 and YRMRD0003 have been returned with no significant copper or gold intersections encountered. See Table 2 for drill hole details. Drill hole core samples are however, being characterised for alteration studies to be used as an exploration vector towards potentially mineralised positions.

Yarindury diamond drilling hole Summary. 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 mineralisation style. “Line 2 of the initial three lines of seven drilled have returned anomalous assay results, in AC drilling of the oxidised portion of the geological profile. The intersections recorded in EPAC0001 and EPAC0003 shows ore grade gold mineralisation located in the targeted structural position coincident with an important geological contact. These results demonstrate this zone is a fertile location for orogenic gold mineralisation. “The assay results in holes EPAC0001 and EPAC0003 show that the alteration and mineralisation intersected at East Peak Hill appears to be very similar to the nearby Tomingley-style gold mineralisation and alteration. “The remaining four lines of AC drilling located further south also test this prospective contact position. We look forward to receiving assay results for these remaining lines which are expected in the next 3-4 weeks.” –– Ends –– For further information, please contact: 4August2024 ASX Announcement 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.

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 4August2024 ASX Announcement 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. Talisman believes there is significant potential for the discovery of substantial copper and gold mineralisation within this land package and is undertaking active exploration to test a number of these targets.

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. Logging of diamond drilling includes geotechnical data, RQD and core 4August2024 ASX Announcement Criteria JORC Code explanation Commentary recoveries. • Drill core is photographed prior to any cutting and/or sampling and then stored onsite in Talisman Core yard in Condobolin. Photographs are available for every diamond drillhole completed. • Mud Rotary chips are photographed in trays. • All information collected are 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 exploration and to support appropriate mineral resource estimation, mining studies, and metallurgical studies. Sub-sampling techniques and sample preparation • If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. TLM Auger Drilling • Auger samples were dried, crushed (where required), split and pulverised (total prep) to produce a 0.25g sub sample for base metal analysis or a 50g sub sample for gold analysis by fire assay. • QAQC protocols for all Auger sampling involved the use of Certified Reference Material (CRM) as assay standards. • All QAQC controls and measures were routinely reviewed. • Sample size is considered appropriate for geochemical sampling for base-metal and gold mineralisation given the nature of drilling and anticipated distribution of mineralisation. TLM AC Drilling • AC samples were dried, crushed (where required), split and pulverised (total prep) to produce a 25g sub sample for gold and multi-element analysis by aqua regia. • QAQC protocols for all AC sampling involved the use of Certified Reference Material (CRM) as assay standards. • All QAQC controls and measures were routinely reviewed. • Sample size is considered appropriate for geochemical sampling for gold and multi-element mineralisation given the nature of drilling and anticipated distribution of mineralisation. TLM MR/DD Drilling: • Diamond drill core (HQ) samples collected for analysis are longitudinally cut in half, and quarters for the QAQC samples using a using an automated Almonte core saw. Core was placed in boats, holding core in place. • Half core or quarter core sample intervals typically varies from 0.3m to 1.3m in length. 1m sample intervals are favoured and are the most common method of sampling, however sample boundaries do principally coincide with geological contacts. The remaining core is retained in core trays. • DD samples are dried, crushed (where required), split and pulverised (total prep) to produce a 0.25g sub sample for 4August2024 ASX Announcement Criteria JORC Code explanation Commentary base metal analysis or a 30g sub sample for gold analysis by fire assay. • QAQC protocols for all DD sampling involve the use of Certified Reference Material (CRM) as assay standards. • All QAQC controls and measures are routinely reviewed. Sample size is considered appropriate for geochemical sampling for base-metal and gold mineralisation given the nature of drilling and anticipated distribution of mineralisation. • Field duplicates are collected at a 1 in 30 sample rate. Quality of assay data and laboratory tests • 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
