Talisman Mining (ASX: TLM, ‘Talisman’ or ‘the Company’) is pleased to advise that it has commenced a 2,500m Aircore (AC) drilling program (Figure 1) at its Walkers Hill Project, located approximately 60km north-west of Condobolin in NSW. Walkers Hill Project (EL 8571) – AC drilling1 The Walkers Hill Project contains the extensive Walkers Hill gold-in-soil trend, extending over an area of approximately 4.5km by 2.0km The Sheepyard prospect lies at the south-eastern end of the Walkers Hill trend and shows gold-in-soil anomalism over a 1.5km by 1.0km area. Historic and recent exploration results from shallow depths, indicate broad zones of low-grade mineralisation with narrower zones of higher-grade gold (see TLM ASX announcements 17June, 25 July and 15 September 2025) within the Sheepyard Prospect (Figures 2 and 3). Previous drill results include: • RC drilling: o 40m at 0.46g/t Au from 3m (PMV005). o 12m at 0.38g/t Au from surface (TMY027). 4August2024 ASX Announcement 1 ASX: TLM -15 September 2025. o 10m at 0.36g/t Au from 22m (SYRC0001) o 42m at 0.44g/t Au from 4m including 8m at 0.85g/t Au (SYRC0003) Figure 1. Wallis Drilling AC drilling rig at the Sheepyard Prospect. Recent RC Drill Program Results1 During August 2025 Talisman completeda total of five Reverse Circulation (RC) holes for 857mto test the northern most soil geochemical trend at Sheepyard (Figures 2 and 3). The RC drilling intersected broad zones of low-grade gold mineralisation and was reported on 15 September. ASX announcement 15 September 2025. Surface mapping and geological logging show shallow gold mineralisation within the Ordovician-age Girilambone metasediments occurs in association with thin and occasionally brecciated quartz veining interpreted to be in a broad, north-east trending fault zones (Figure 2 and 3). Deeper gold mineralisation encountered in RC drill holes SYRC0001, SYRC0002 and SYRC0004 is associated with thin quartz veining and selvedge disseminated pyrite mineralisation. 4August2024 ASX Announcement 1 ASX: TLM -15 September 2025. Gold mineralisation is associated with anomalous arsenic, antimony and tungsten, typical of orogenic-style gold sulphide mineralisation. Several other mineralised trends have been identified within the Sheepyard gold-in-soil anomaly which this Aircore drilling program is targeting where higher tenor soil anomalies mark potentially higher-grade mineralisation in the near-surface oxide environment. Figure 2. The Sheepyard prospect gold-in-soil geochemical anomaly. The anomaly contains several NE-SW orientated higher tenor trends. RC drilling has tested the northern most trend1 . This AC drilling program will test a further two high tenor trends within the anomaly. Historical and recently completed RC drilling is shown. 4August2024 ASX Announcement 1 ASX: TLM -15 September 2025. Figure 3. Sheepyard Prospect proposed AC drilling plan view.

AC drilling will test the two zones, also trending NE-SW that have been identified and remain largely untested by drilling. 4August2024 ASX Announcement 1 ASX: TLM -15 September 2025. Table 1: Sheepyard Prospect significant intercepts for recent TLM and historic RC drilling using a cut-off grade of 0.2 g/t Au with ≤ 6m internal dilution. Management Comment Talisman’s Managing Director, Andrew Munckton, said: "We are encouraged by the results received from our maiden 2025 drilling program, with the recent 5-hole RC program at the Sheepyard Prospect delivering wide zones of shallow, low-grade gold mineralisation. This includes intercepts of up to 42m at 0.44g/t Au from 4m in hole SYRC0003. “The Aircore drilling program we have just commenced is targeting an additional two, higher tenor trends as defined by the soil geochemistry. The shallow AC drilling will determine if higher grade material exists in the near surface oxide zone which lie above more compelling targets at depth which may be targeted with subsequent geophysical programs and deeper RC drilling. Assays from the current AC drilling program are expected to be available in approximately 4 to 6 weeks. “Success in this AC program would open up the entire 4.5km long zone of mineralisation stretching from Sheepyard to Maroonbah for follow-up exploration. The team now have a much clearer vector for targeting higher- grade mineralisation associated with the NE-SW trending structural features. “Sheepyard remains a small part of the much larger Walkers Hill soil anomaly. The Maroonbah Prospect to the north-west of Sheepyard appears to be the larger and stronger soil anomaly and we are looking forward to accessing this for initial exploration work in early 2026.” –– 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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

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.

Appendix 2 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 (e.g. 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 (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 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. Walkers Hill Project (Historical Drilling) • Triako RC drilling, cited in this report, collected samples via a plastic bag hooked beneath a cyclone mounted on the side of the drill rig. Approximately 20 kg was collected per 1 metre sample interval. Samples were speared on site and composited into 4m intervals for assay. Several 1m speared samples were also collected, with gold assay results generally within a few percent of the corresponding 1m riffle split intervals. This suggests that gold is relatively evenly distributed, and the spearing method of sampling is adequate. Reference: Triako Third Annual Exploration Report, 2003 (R00048055). • Paradigm Metals. RC drilling cited in this report, provided no specific information on sampling techniques. However, it was noted that samples were submitted for assay as composites over 2m, 3m, 4m, and 6m intervals. Reference: Paradigm Metals Licence 7697 Maroondah First Annual Report, 2012 (RE0002711). 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 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 4August2024 ASX Announcement 1 ASX: TLM -15 September 2025. Criteria JORC Code explanation Commentary nominal 140mm size. • The core was orientated using an AXIS single shot gyro. Walkers Hill Project (Historical Drilling) • Triako RC drilling, cited in this report, was conducted in 2002 by Geological Ore Services of Cobar using an Edson 300 drill rig mounted on a Toyota 4WD. Compressed air was supplied by a 175 psi / 300 cfm compressor mounted on a trailer towed by the support vehicle. The capacity of the compressor limited drilling depths to between 40 and 60 m. Reference: Triako Third Annual Exploration Report, 2003 (R00048055). • Paradigm Exploration RC drilling, cited in this report, comprised six RC holes (PMV001–PMV006). However, no information was provided regarding the drilling contractor or specific drilling techniques employed. Reference: Paradigm Exploration, Licence 7697 Maroondah First Annual Report, 2012 (RE0002711). 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 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. Walkers Hill Project (Historical Drilling) • Triako RC drilling, cited in this report, collected samples in plastic bags hooked beneath a cyclone mounted on the side of the drill rig. Approximately 20 Kg of sample was recovered per 1m interval. Reference: Triako Third Annual Exploration Report, 2003 (R00048055). • Paradigm Exploration, RC drilling cited in this report, provided no information on sample recovery. Reference: Paradigm Exploration, Licence 7697 Maroondah First Annual Report, 2012 (RE0002711). 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 RC Drilling • RC 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. • RC logging is both qualitative and quantitative depending on the field being logged. • All RC drill-holes are logged in full to end of hole. • All RC chip trays are photographed and then stored onsite in TLM secure premises. • All information collected is entered directly into laptop 4August2024 ASX Announcement 1 ASX: TLM -15 September 2025. Criteria JORC Code explanation Commentary 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. Walkers Hill Project (Historical Drilling) • Triako RC drilling, cited in this report, involved geological logging of each sample, with representative samples retained in plastic chip trays and stored at the core yard at their Mineral Hill facility. Lithological codes, sample intervals, and collar survey data were entered into Excel spreadsheets at the Mineral Hill site. Reference: Triako Third Annual Exploration Report, 2003 (R00048055). Paradigm Exploration RC drilling cited in this report, provided no detailed information on geological logging methods; however, a logging summary sheet was included in their company report. Reference: Paradigm Exploration, Licence 7697 Maroondah First Annual Report, 2012 (RE0002711). 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 RC Drilling • RC 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 RC 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. • Field duplicates were geologically targeted and located within zones of mineralisation, where intersected. Walkers Hill Project (Historical Drilling) • Triako RC drilling, cited in this report, involved collecting samples in plastic bags hooked beneath a cyclone mounted on the side of the RC drill rig. Approximately 20 kg of material was recovered per 1m sample interval. Samples were speared on site and composited into 4m intervals for assay. Several individual 1m speared samples were also collected, with assay results generally within a few percent of the corresponding 1m riffle split intervals. This suggests that gold distribution is relatively uniform and that the spearing method was adequate for sampling purposes. Reference: Triako Third Annual Exploration Report, 2003 (R00048055). • Paradigm Exploration RC samples, cited in this report, were collected as 2, 3, 4, and 6m composites using a sample spear.
