Announcement PDF Talisman Mining | Suite 1, Ground Floor, 33 Colin St, West Perth 6005 ABN 71079 536 495 talismanmining.com.au ASX:TLM 9February2026 ASX Announcement 1 Aircore drilling delivers strong near surface gold results at Sheepyard – Walkers Hill Project, NSW 15m at 1.10g/t Au from surface and 9m at 1.05g/t Au from 30m within a broader mineralised zone Highlights: Lachlan Projects, NSW Walkers Hill Gold Project • Aircore (AC) drilling completed recently at the Sheepyard Prospect has intersected a broad zone of shallow gold mineralisation containing several intersections of higher-grade gold, with assay results including: • SYAC0043 o 15m at 1.10g/t Au from surface including 6m at 1.95g/t Au; and • SYAC0041 o 9m at 1.05g/t Au from 30m; and • SYAC0040 o 6m at 0.63g/t Au from 54m to end-of-hole • Sheepyard forms part of the larger Walkers Hill gold-in-soil anomaly, sitting on a major geological contact and stretching over 4.5km north-west of the recent drilling. • Sheepyard contains three NE-SW oriented, higher tenor geochemical trends within the broader anomalous soil geochemistry. • The recent 2,229m AC program tested these geochemical trends, with two lines spaced 200m apart which penetrated to a vertical depth of generally 25m to 50m. • The higher-grade intersections occur within a sequence of five consecutive drill-holes (SYAC0040 to SYAC0044), which collectively indicate a significant zone of anomalous near-surface gold mineralisation approximately 60 metres wide (True width not known). • The higher-grade zones are coincident with sheared, altered, quartz-veined and occasionally brecciated quartz which strike in NE-SW direction and dip steeply north-west. • Further AC drilling is planned to test extensions of the broad mineralised zones intersected in the initial two lines of drilling. Talisman Mining (ASX: TLM, ‘Talisman’ or ‘the Company’) is pleased to report assay results from the 2,229m Aircore (AC) drilling program completed late last year at its Walkers Hill Gold Project, located approximately 60km north-west of Condobolin in NSW. Walkers Hill Project (EL 8571) – Background1 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 displays gold-in-soil anomalism over an area of 1.5km by 1.0km. 4August2024 ASX Announcement 1 ASX: TLM – 17 June, 25 July and 15 September 2025. Historical and earlier Talisman exploration results1 from shallow depths indicate the presence of broad zones of gold mineralisation with narrower zones of higher-grade gold (see TLM ASX announcements 17June, 25 July and 15 September 2025) at the Sheepyard Prospect (Figures 2 and 3). Figure 1. Wallis Drilling AC drilling rig operating at the Sheepyard Prospect. Recent AC Drill Program Results During November 2025, Wallis Drilling (Figure 1) completed a total of 49 Aircore (AC) holes for 2,229m in two lines spaced 200m apart to test the southern part of the soil geochemical trend at Sheepyard (Figures 2, Figure 3, Table 1 and Table 2). Drilling was angled at 60 degrees grid south and penetrated the Oxide and Transitional Zone of weathering to the top of fresh rock at approximately 30m-60m down-hole (25m-50m vertical). Sampling was undertaken on 3m composite samples for each drill hole and assayed for gold. Hand-held XRF results were also collected for pathfinder elements – Arsenic, Antimony and Tungsten – to assist with trend interpretation. Assaying of 3m composites for gold reported in this announcement are by 50g Fire Assay. The AC drilling intersected a broad zone of gold mineralisation in the Western Line of AC drilling and a lesser zone of mineralisation in the Eastern Line. Gold mineralisation is reported from several consecutive holes, particularly on the Western Line. Results are reported by 3m composite sample and include: 4August2024 ASX Announcement 1 ASX: TLM – 17 June, 25 July and 15 September 2025. Western Line • SYAC0040 – 6m at 0.63g/t Au from 54m to end-of-hole • SYAC0041 – 9m at 1.05g/t Au from 30m • SYAC0042 – 15m at 0.26g/t Au from 6m • SYAC0043 – 15m at 1.10g/t Au from surface including 6m at 1.95g/t Au • SYAC0044 – 21m at 0.38g/t Au from surface Eastern Line • SYAC0022 – 6m at 0.47g/t Au from 39m to end-of-hole • SYAC0024 – 6m at 0.69g/t Au from 21m Surface mapping and geological logging show that shallow gold mineralisation within the Ordovician-age Girilambone metasediments occurs in association with sheared, veined and occasionally brecciated quartz- pyrite alteration zones, interpreted to be in broad, north-east trending fault zones (Figure 2 and 3). Deeper gold mineralisation encountered in RC drilling further north is associated with thin quartz veining and selvedge disseminated pyrite mineralisation1 . Gold mineralisation is associated with anomalous arsenic, antimony and tungsten, typical of orogenic-style gold sulphide mineralisation1 . The AC drilling program targeted higher tenor soil anomalies which mark higher-grade mineralisation in the near-surface oxide environment. The Western Line of AC drilling (Figure 3 and Figure 4) shows a broad zone of near-surface gold mineralisation which contains a coherent zone of higher grade intersected in five consecutive holes, SYAC0040 to SYAC0044. The Western Line higher grade zone spans a distance of approximately 60m (true width not known) and contains both higher grade intersections (9m at 1.05g/t Au from 30m in SYAC0041 and 15m at 1.10g/t Au from surface in SYAC0043) which correspond to a zone of altered, quartz veined, pyrite-rich and sheared sediments interpreted to be a NE-SW trending shear zone emanating from the interpreted position of the Erimeran Granite contact, located approximately 600m south-west of the Western Line of AC drilling Interpretation and Next Steps in the Exploration Program The Western Line of AC drilling indicates significant widths of near-surface gold mineralisation containing zones between 6m and 15m wide (true width not known) of >1.0g/t Au gold mineralisation within the broader 60m zone. The higher-grade zones intersected to date are interpreted to trend NE-SW. The overall trend of the 4.5km-long anomalous soil geochemistry within the greater Walkers Hill area trends NW- SE and is proximal to and strongly associated with the mapped contact between the large Erimeran Granite intrusion and the host rock Girilambone Sediments. Additional mapping and soil geochemical sampling programs are planned at Maroonbah 3km north-west of Sheepyard to bring further detail to this association. A follow-up program of two additional lines of AC drilling further west of the Western Line will be undertaken once access to Maroombah and additional soil geochemical programs have been completed later in 2026 to test the extent of the higher-grade mineralisation intersected to date. 4August2024 ASX Announcement 1 ASX: TLM – 17 June, 25 July and 15 September 2025.

Management Comment Talisman’s Managing Director, Andrew Munckton, said: “We are very encouraged by the recent shallow AC drilling results at Sheepyard. Both lines of AC drilling intersected shallow zones of gold mineralisation that coincide with sheared and altered sediments, rich in quartz veining and pyrite mineralisation. These zones are interpreted as a late-stage, NW-trending fault zone that is mapped by surface quartz veining and the strongest arsenic and gold anomalies seen in the soil geochemistry. “Importantly, in the Western Line of AC drilling, the broader zone of gold mineralisation contains a number of higher-grade intersections such as 15m at 1.1g/t Au from surface in SYAC00043 that indicate both the presence of ore grade mineralisation at surface and the potential for these higher-grade zones to persist along strike to the south-west and at depth below the oxide zone tested in this round of drilling. “The next steps in the exploration program at the greater Walkers Hill project include additional geological mapping and soil geochemistry surveys at Maroonbah followed by further lines of AC drilling at Sheepyard, stepping-out in a westerly direction to confirm the extent of the higher grade near-surface mineralisation as we approach the regionally important contact with the Erimeran Granite to the west. “This AC drilling program has shown significant zones of ore grade gold mineralisation at surface and opened up the entire 4.5km-long zone of surface gold anomalism stretching from Sheepyard to Maroonbah, and which follows the Erimeran Granite contact, for follow-up exploration. “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 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. 4August2024 ASX Announcement 1 ASX: TLM – 17 June, 25 July and 15 September 2025. 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 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 50g sub sample was taken for fire assay for gold with ICP-AAS finish. 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 4August2024 ASX Announcement 1 ASX: TLM – 17 June, 25 July and 15 September 2025.

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 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 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. • 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).

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. 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.

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 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 RC Drilling 4August2024 ASX Announcement 1 ASX: TLM – 17 June, 25 July and 15 September 2025.
