A comprehensive geological, geochemical and geophysical review across all TLM Mineral Hill- Canbelego Volcanic Belt (MHCVB) tenure was completed during the June Quarter. This review identified two high-priority targets in the Walkers Hill gold geochemical trend, with an initial 5-hole/857m Reverse Circulation (RC) drilling program completed over the new Sheepyard Prospect during the September Quarter. Figure 1: Talisman’s Lachlan Project which covers the Mineral Hill-Canbelego Volcanic Belt (MHCVB) on a regional TMI Airborne Magnetic image. High-grade base metals and copper-gold deposits in the belt include CSA, Peak, Hera, Federation and Mineral Hill. Other Talisman tenure in the area (to the east and south-east of Cobar and north of Condobolin) is also shown. 1 ASX: TLM -15 September 2025. talismanmining.com.au 3 Figure 2: Lachlan Projects southern tenements area with geology and gold-in-soil geochemistry. The Walkers Hill gold-in-soil geochemical trend (highlighted) is the largest and most coherent trend in the area, spanning an area of approximately 10km by 2.5km, and is divided into the Maroonbah and Sheepyard prospects. Planned geochemical coverage in-fill Auger drilling programs across prospective trends are also highlighted. talismanmining.com.au 4 Walkers Hill1 The Walkers Hill Project 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 17th June and 25th July) within the Sheepyard Prospect (Figures 3 and 4) of the Walkers Hill Project include: • RC: 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. During August 2025, Talisman completed a total of five Reverse Circulation (RC) holes for 857m to test both historical near-surface mineralisation and the PDIP chargeability feature, with holes designed up to 200m depth (Figures 3 to 6). The drilling tested part of an extensive gold-in-soil geochemical anomaly above the strong Pole-Dipole Induced Polarisation (PDIP) chargeability. Four of five 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 6m at 0.38g/t Au from 124m including 4m at 0.99g/t Au • SYRC0003 o 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 Ordovician-age Girilambone metasediments occurs within thin quartz veining interpreted to be in a broad north-east trending fault zone. 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 orogenic-style 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. A follow up Aircore drilling program is planned. 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. talismanmining.com.au 5 Figure 3: The Walkers Hill Project gold-in-soil geochemical trend. The trend contains the Maroonbah and Sheepyard Prospects. At Sheepyard, the location of PDIP geophysical survey lines, historical and completed RC drilling is shown. talismanmining.com.au 6 Figure 4: Sheepyard Prospect RC drilling plan view. Recent RC drilling locations over contoured gold-in-soil results indicating a NE-SW trend to the surface expression of mineralisation. RC drilling has tested only the north-western part of anomalous soil geochemistry. Three other zones also trending NE-SW have been identified and remain largely untested by drilling. talismanmining.com.au 7 Figure 5: Sheepyard Prospect RC drilling over PDIP chargeability section. See Figure 4 for section location. Deeper gold intersections in SYRC0001, SYRC0002 and SYRC0004 are coincident with the projected position of the PDIP chargeability anomaly. Figure 6: Sheepyard Prospect RC drilling cross-section. See Figure 4 for section location. RC drilling is targeting both near-surface oxide mineralisation (intersected in SYRC0001 and SYRC0003) marked by the gold-in-soil anomaly and deeper hypogene mineralisation (intersected in SYRC0001, SYRC0002 and SYRC0004) associated with the extensive chargeability anomaly that sits below the anomalous gold-in-soil results. talismanmining.com.au 8 Macquarie Arc Projects, NSW Yarindury (EL 9679) – Geophysical survey2 Yarindury is located 30km north-east of Dubbo within the Molong Volcanic Belt, which forms part of the Macquarie Volcanic Arc in central-western NSW. The tenement lies along the same prospective corridor as Alkane Resources’ (ASX: ALK) Boda–Kaiser Project, 20km to the south-east, and Newmont’s (NYSE: NEM) worldclass Cadia copper-gold mine, located 100km along strike to the south. Talisman completed a three-line, 13km, Induced Polarisation and Magneto-Telluric (IP-MT) ground geophysical survey at the project during the Quarter, with survey data revealing buried chargeability targets. A maiden drilling program to test the targets generated in this geophysical program is planned. Figure 7: Yarindury Project area on magnetic image (RTP). Completed ground geophysical IP (Induced Polarisation) and MT (Magnetotelluric) survey line locations are illustrated. 2 ASX: TLM -25 July 2025. talismanmining.com.au 9 East Peak Hill (EL 9395) – Auger Drilling3 EL 9395 is located in central western NSW zone on the Junee–Narromine Volcanic Belt (JNVB) of the Macquarie Volcanic Arc. The JNVB extends over 200km north–south and its northern portion hosts Alkane Resources’ (ASX: ALK) Tomingley Gold Mine (shear hosted vein deposits) and the Peak Hill high-sulphidation-epithermal gold deposit. The EL is situated immediately south-east of the Tomingley gold mine. Talisman interprets East Peak Hill to be highly prospective for orogenic shear-hosted vein style gold mineralisation, high sulphidation vein style gold and porphyry style copper-gold mineralisation. East Peak Hill Project contains interpreted andesitic volcanic units striking north–south along the length of the tenement. An initial scout auger survey commenced in June 2025, targeting areas of shallow to moderate cover. In places the overlying cover exceeded the penetration depth of approximately 10m of the auger rig. Aircore drilling in these areas as illustrated in Figure 9 is scheduled to complete the initial program. Figure 8: Talisman Exploration Licences across the Narromine-Junee Volcanic Belt. The northern block located adjacent to the Tomingley Gold Mine is the East Peak Hill (EL 9395) project area. Additional TLM tenure is also shown. 3 ASX: TLM -17 June 2025. talismanmining.com.au 10 Figure 9: EL 9395 with location of initial auger program in broadly spaced lines targeted above interpreted N-S striking andesite units. Aircore drilling to follow up the auger and complete the initial program is planned to be caried out in the December quarter. talismanmining.com.au 11 Gawler Craton – South Australia Mabel Creek – June half drilling results4 Talisman acquired 100% ownership of the Mabel Creek IOCG Project in June 2023, securing a 1,048km² landholding approximately 30km west of Coober Pedy. The project is located over the post mineral covered parts of the Northern Gawler Craton, spanning the Nawa Domain and Mount Woods - Coober Pedy Ridge Complex. These geological domains are separated by a major east–west trending structural corridor known as the Karari Shear and Horse Camp Fault (Figure 9). The Gawler Craton is highly prospective for large-scale Iron Oxide Copper Gold (IOCG) systems and hosts world-class deposits such as Olympic Dam, Carrapateena, and Prominent Hill, as well as recent discoveries including Oak Dam and Emmie Bluff. Figure 10: Simplified regional geology of the northern Gawler Craton showing Mabel Creek project area, major structural geological features and mineral deposits. Following a detailed ground gravity survey completed in 20244 , Talisman conducted an initial diamond drilling program in March–April 20255 . Three holes (MCMRD001–MCMRD003), totalling 1,367m were completed which tested near-coincident magnetic and gravity anomalies under post mineral cover, in the Nawa Domain north of the Horse Camp Fault (Figure 10 and Figure 11). Basement rocks were intersected at expected depths of between 205m to 305m. Diamond drilling intersected a suite of metamorphic lithologies including granite gneiss, pegmatitic granite, talismanmining.com.au 12 amphibolite and calc-silicate rocks, with variable levels of hydrothermal alteration observed in most holes. Result in hole MCMRD002, which tested anomaly P2 adjacent to the Horse Camp Fault were encouraging. This hole intersected a broad hydrothermal alteration zone with elevated molybdenum (Mo) and rare earth elements (REE)1 . The significance of this zone as a potential vector toward IOCG mineralisation is being assessed further via detailed geochemical, petrological and geochronological studies. The tenure remains prospective for IOCG-style mineralisation. Following a review of the data, the area south of the Horse Camp Fault with likely shallow post mineral cover, has been identified as an exploration priority where several near-coincident magnetic and gravity anomalies are located within the Mt Woods -Coober Pedy Ridge Complex. A second phase of exploration drilling is planned. Ongoing geophysical modelling, incorporating insights from the initial drilling is underway to refine target drill hole locations.

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 joint venture agreements. 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 1000km2 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. Mable Creek is surrounded by similar tenure owned and being actively explored by Australia’s biggest resource companies including BHP, Rio Tinto and FMG. talismanmining.com.au 15 Competent Person’s Statement Information in this announcement that relates to Exploration Results and Exploration Targets is based on and fairly represents information and supporting documentation compiled by Mr Andrew Munckton, who is a member of the Australasian Institute of Mining and Metallurgy.

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. • RC Drilling 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 are 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. • Diamond drill core samples, either PQ, HQ3 or NQ2 in size diameter, are either cut in half longitudinally or a quarter longitudinally, using an automated Almonte core saw with core placed in boats, holding the core in place. Core sample intervals varied from 0.2 to 1.3m in length but were predominantly aligned to 1m intervals or with sample boundaries which respected geological contacts. • 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/DD 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. A 50g sub sample was also taken for fire assay for gold with ICP-AES finish. • Mud Rotary (MR) chips will be sampled from sieved 6m composites and will be analysed using a portable XRF. 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). • 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 • Diamond Drilling cited in this report at the talismanmining.com.au 19 Criteria JORC Code explanation Commentary Durnings Project was undertaken by DDH1 Drilling Pty LTD ùsing an Evolution FH3000 or a Multipurpose UDR1200 truck mounted rig. RC components in DRRCD0027 and DRRCD0028 was undertaken by the Multipurpose UDR 1200. • Diamond drilling undertaken by DDH1 Drilling Pty Ltd Multipurpose UDR1000 truck mounted rig at Mabel Ck and Yarindury. Mud Rotary drilling was completed through the thick (~200-300m) Mesozoic and/or Palaeozoic cover sequences. Diamond drill tails were undertaken in the basement sequence when intersected. • Down hole surveys were undertaken approximately every 30m using an Axis north seeking gyro. 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. 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. Diamond Drilling • Core recovery data 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. 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 at the Talisman Condobolin yard. • 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 talismanmining.com.au 20 Criteria JORC Code explanation Commentary exploration and to support appropriate mineral resource estimation, mining studies, and metallurgical studies. Diamond Drilling (DD) and Mud Rotary drilling (MR) • Logging was carried out on site once geology personnel retrieve core or chip trays from the drill rig site. • 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 drill-holes are logged in full to end of hole. • Collar coordinates, azimuth, dip, depth and sampling intervals are also recorded. • Logging is both qualitative and quantitative depending on the field being logged. Logging of diamond drill core includes geotechnical data, RQD and core recoveries. • Diamond drill core is photographed prior to any cutting and/or sampling and then stored onsite in Talisman Condobolin Yard. • Mud Rotary chips will be photographed in trays. • 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 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 full 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- 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 30g 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 talismanmining.com.au 21 Criteria JORC Code explanation Commentary 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. duplicates were collected at a 1 in 30 sample rate Diamond Drilling • Diamond drill core (NQ3, HQ or PQ) samples collected for analysis are longi
