Talisman’s CEO, Todd Ross said: “These results continue to build the case for Sheepyard as a potentially large- scale gold system. We’re seeing consistent, shallow gold mineralisation across an unconstrained 800m of strike and, importantly, these intersections sit on the margins of an IP chargeability anomaly that has yet to be tested by drilling. “When considered alongside the broader 5.5km soil anomaly at Walkers Hill, Sheepyard is shaping up as a high- priority target for the Company. “Our next phase of drilling is designed to build on this momentum, with follow-up AC drilling aimed at extending the footprint of the mineralised system and deeper RC drilling planned to provide a definitive test of the IP anomaly at depth, which has the potential to represent the core of the mineralised system and host higher-grade gold mineralisation.” The Walkers Hill Gold Project covers a consolidated land package that extends over a strike length of approximately 90km and contains a number of highly prospective mineralised litho-structural domains within the Lachlan Fold Belt, NSW (Figure 1). Figure 1: Regional Location Plan of Walkers Hill Project talismanmining.com.au 3 The Sheepyard Prospect is located on the southern end of the Walkers Hill Gold Project and is defined by an approximately 5.5km long geochemical anomaly (>25ppb Au). Additionally, limited programs of historical drilling returned highly anomalous gold results (see ASX announcements dated 17 June, 25 July and 15 December 2025) within this larger area (Figure 2a & b). To build this position, Talisman has undertaken systematic programs of high-quality exploration at the Sheepyard Prospect with the completion of surface geochemistry, two lines of IP surveying, a 5-hole program of RC drilling and two programs of AC drilling (89 holes for 3,883m). Recent AC Drill Program Results The recent AC drilling program was designed to expand on the previous drilling programs and to further test the interpreted up-plunge position of the modelled IP chargeability anomaly. The results include (see Table 1 and Appendix 1 for additional detail): • SYAC0085: 9m at 0.94g/t Au from 42m (includes 6m at 1.28g/t Au) • SYAC0088: 15m at 0.55g/t Au from 3m (includes 9m at 0.67g/t Au) and 15m at 0.46g/t Au from 30m (includes 3m at 0.97g/t Au) • SYAC0082: 12m at 0.68g/t Au from 21m (includes 9m at 0.78g/t Au – bottom of hole) • SYAC0083: 12m at 0.47g/t Au from 6m (includes 3m at 0.82g/t Au) • SYAC0059: 9m at 0.57g/t Au from 18m (includes 3m at 1.02g/t Au) • SYAC0064: 9m at 0.54g/t Au from 12m (includes 3m at 0.88g/t Au) • SYAC0067: 9m at 0.38g/t Au from 30m (includes 3m at 0.54g/t Au) This work has confirmed the presence of an emerging, large gold system over what is currently an unconstrained approximately 800m of strike (Figure 2a & b). As now defined, the gold is interpreted to be marginal to a strong north-west plunging IP chargeability anomaly that has not been effectively tested at depth (Figure 3 and 4). Consideration is also being given to the presence of a series of north-east/south-west trending structures. The shallow gold mineralisation is associated with sheared, veined and at times brecciated quartz-pyrite alteration zones, hosted by a package of sediments. There is a strong association with arsenic, antimony and tungsten which is typical of orogenic-style gold mineralisation. Given that significant bedrock gold mineralisation has now been confirmed beneath the extensive high-tenor geochemical anomalism that extends over the approximately 5.5km strike length, the Company is confident that the broader Sheepyard Prospect represents a large-scale, high-priority target. talismanmining.com.au 4 Figure 2(a): Sheepyard to Marranoonbah Au Trend Figure 2(b) Sheepyard Prospect talismanmining.com.au 5 Figure 3: Cross Section through Sheepyard Prospect cut on IP Survey Line 1 - Drilling intersections from this phase are in red with previous drilling in orange. Figure 4: Oblique Long section through Sheepyard Prospect with modelled and projected IP chargeability - Drilling intersections from this phase are in red with previous drilling in orange. The north-westerly plunging IP chargeability anomaly imaged in the long section (Figure 4) is interpreted to reflect disseminated pyrite associated with sheared, altered sediments and gold-bearing quartz veining. Near-surface AC holes including SYAC0082 and SYAC0083, both ending in mineralisation at the bottom of hole, are interpreted as the surface expression of this larger, untested target at depth. Hematite alteration in the shallow, oxidised zone likely reflects destruction of primary sulphides, dampening the near-surface IP response and suggests the untested anomalies below could represent multiple subparallel zones which form part of a much larger NW striking, primary sulphide-gold system. talismanmining.com.au 6 Exploration Program – Next Steps Additional programs of AC and RC drilling are currently being planned with the aim of extending the footprint of the Sheepyard Prospect gold mineralised system and providing a more detailed test of the IP chargeability anomaly at depth. This work will form a key part of evaluating the broader 5.5km-long anomaly. Other Projects – East Peak Hill Project Update Talisman’s 100%-owned East Peak Hill Project is located within the Junee-Narromine Belt approximately 10km south of the Tomingley Gold Mine (Alkane) and approximately 5km east of the Peak Hill Gold Mine (Alkane). Talisman is targeting the same style of orogenic gold deposits within the folded extension of the host stratigraphy at both mines (Figure 5, left). Figure 5: Location Plan - TLM Tenure within the Macquarie Arc Volcanics (left) and East Peak Hill Prospect with Interpreted Au Trend (Target Horizon) over Magnetics (right). A program of wide-spaced, reconnaissance AC drilling completed in May 2026 (see ASX announcement 20 May 2026) confirmed the prospective host stratigraphy and identified a strong anomalous gold trend over an interpreted approximately 5km strike length. To gain a broader understanding of the East Peak Hill Project, a recent program of AC drilling (15 holes for 1,103 metres) was completed to test a number of targets generated outside of this main mineralised trend. This phase of drilling did not return any significant results (Table 3) and has confirmed that the focus of ongoing exploration will be on the central trend (Figure 5, right). In-fill programs of AC drilling are currently being planned. –– Ends –– talismanmining.com.au 7 For further information, please contact: Todd Ross – Chief Executive Officer +61 8 9380 4230 Nicholas Read (Media inquiries) +61 4199 29046 This release has been authorised by the Board of Talisman Mining Limited. 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 and through a joint venture agreement. 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 believes there is significant potential for the discovery of substantial base metals and gold mineralisation within this land package and is undertaking active exploration to test a number of these targets. Talisman also has secured access to over 1040 km2 of highly prospective tenure in South Australia’s Gwaler Craton known as the Mabel Creek Project. Mabel Creek is prospective for large scale Iron Oxide Copper Gold (IOCG) deposits and intrusion related rare earths and battery metals mineralisation. Mabel Creek is surrounded by similar tenure owned and being actively explored by Australia’s biggest resource companies including BHP, Rio Tinto and FMG.

JORC Tables Section 1 & 2 Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections.) Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). 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 (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg 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 (eg submarine nodules) may warrant disclosure of detailed information. 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 3-4kg 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 50g sub sample was taken for fire assay for gold with ICP-AAS finish. • Multi-element analysis by four acid digest with an ICP-MS finish (ME-MS61) was conducted for BOH samples at the EPH Prospect for litho-geochemistry purposes only. TLM RC Drilling • RC samples are collected at either one metre or two 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. • RC samples undergo routine 2 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. • RC 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. Drilling techniques • Drill type (eg core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is TLM AC drilling • AC drilling cited in this report was undertaken by Wallis Drilling Pty Ltd using a Mantis 80 drill rig with onboard compressor. talismanmining.com.au 12 Criteria JORC Code explanation Commentary oriented and if so, by what method, etc). • AC drilling was completed with a face sampling blade of nominal 120mm size. TLM RC drilling • RC drilling cited in this report was undertaken by Strike Drilling Pty Ltd using a LC36 (KWL 700) truck-mounted Reverse Circulation drill rig. A truck-mounted booster and compressor provided high pressure air with an auxiliary compressor used where ground conditions warranted. • RC drilling was completed with a face sampling hammer of nominal 140mm size. 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 preferential loss/gain of fine/coarse material. TLM AC Drilling • AC drill sample recovery is generally high. • 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 RC Drilling • RC drill sample recovery is generally high with sample recoveries and quality recorded in the database by the logging geologist. • 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. 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 AC Drilling • AC logging records lithology, mineralogy, mineralisation, alteration, structure, weathering, colour and other primary features of the rock samples and is considered 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 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.
