Talisman Mining (ASX: TLM, ‘Talisman’ or ‘the Company’) is pleased to advise that it has received laboratory assay results from the recently completed program of Reverse Circulation (RC) drilling at its Walkers Hill Project, located approximately 60km north-west of Condobolin in NSW, as indicated in announcements of 17th June and 25th July 2025. Talisman Mining | Suite 1, Ground Floor, 33 Colin St, West Perth 6005 ABN 71079 536 495 talismanmining.com.au 1 4 August 2024 ASX Announcement Walkers Hill Project (EL 8571) – RC drilling The Walkers Hill Project (Figure 1 and 2) contains the extensive Walkers Hill gold-in-soil trend, extending over an area of approximately 4.5km by 2.0km Historical exploration results (see TLM ASX announcements 17 th June and 25th July) within the Sheepyard Prospect (Figures 3 and 4) of the Walkers Hill Project include: • • RC drilling: o 40m at 0.46g/t Au from 3m (PMV005). o 12m at 0.38g/t Au from surface (TMY027). o All mineralised holes ended in oxide and drilling was limited to 60m below surface. A Pole Dipole Induced Polarisation (PDIP) geophysical survey on two lines completed in 2023 revealed a significant chargeability anomaly below the mineralised historical RC drill intercepts (Figure 4). Figure 1. Strike Drilling RC rig drilling at the Sheepyard Prospect. talismanmining.com.au 2 4 August 2024 ASX Announcement RC Drill Program Results During August 2025 Talisman completed a total of five Reverse Circulation (RC) holes for 755m to test both historical near-surface mineralisation and the PDIP chargeability feature, with holes designed up to 200m depth (Figures 2 to 5). The drilling tested part of an extensive gold-in-soil geochemical anomaly above the strong Pole-Dipole Induced Polarisation (PDIP) chargeability feature. Four of five holes intersected broad zones of low-grade gold mineralisation, with laboratory assays including: • • SYRC0001 o 10m at 0.36g/t Au from 22m; and o 41m at 0.29g/t Au from162m SYRC0002 o • SYRC0003 o • 16m at 0.38g/t Au from 124m including 4m at 0.99g/t Au 42m at 0.44g/t Au from 4m including 8m at 0.85g/t Au SYRC0004 o 24m at 0.58g/t Au from 124m including 14m at 0.86g/t Au Surface mapping and geological logging of RC chips show shallow gold mineralisation within the Ordovicianage Girilambone metasediments occurs within thin quartz veining interpreted to be in a broad north-east trending fault zone (Figure 3). Deeper gold mineralisation encountered in holes SYRC0001, SYRC0002 and SYRC0004 is associated with thin quartz veining and selvedge disseminated pyrite mineralisation, coincident with the position of the PDIP conductor. Shallow and deeper gold mineralisation is anomalous in arsenic, antimony and tungsten, typical of orogenicstyle gold sulphide mineralisation. Several other mineralised trends have been identified within the Sheepyard gold-in-soil anomaly which warrant follow-up for both the near-surface oxide and deeper hypogene mineralisation. Sheepyard is part of a larger, Walkers Hill Project gold-in-soil trend along a major geological contact which stretches for over 4.0km to the north-west of the recent drilling (Figure 2). talismanmining.com.au 3 4 August 2024 ASX Announcement Figure 2.

Management Comment Talisman’s Managing Director, Andrew Munckton, said: "We are encouraged by the results received from our maiden 2025 drilling program at the Walkers Hill Project, with the recent 5-hole RC program at the Sheepyard Prospect delivering wide zones of shallow, low-grade gold mineralisation in four of the five holes drilled. This includes intercepts of up to 42m at 0.44g/t Au from 4m in hole SYRC0003. “In addition, the RC drilling has also confirmed that the PDIP chargeability anomaly at Sheepyard is associated with elevated pyrite and alteration which accompanies the gold mineralisation. This deeper mineralisation has been intersected over broad zones of up to 40m down-hole and, while generally low grade, does contain narrower intervals of higher-grade mineralisation such as 14m at 0.86g/t Au in SYRC0004. “Importantly, the mineralisation can be detected using geophysics – and we are encouraged to see the potential for higher gold grades in parts of the mineralisation. " “This opens 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 these features and major structural positions. “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 the December quarter.” –– Ends –– For further information, please contact: Andrew Munckton - Managing Director +61 4 3563 5598 talismanmining.com.au 7 4 August 2024 ASX Announcement Nicholas Read (Media inquiries) +61 4199 29046 This release has been authorised by the Board of Talisman Mining Limited. talismanmining.com.au 8 4 August 2024 ASX Announcement 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 Gawler 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.

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. Commentary TLM RC Drilling • • • • Walkers Hill Project (Historical Drilling) • • Drilling techniques • Drill type (e.g. core, reverse circulation, openhole 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). 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 multielement 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. 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.
