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 Lachlan Project A comprehensive geological, geochemical and geophysical review across all TLM Mineral Hill-Canbelego Volcanic Belt (MHCVB) tenure has just been completed (Figure 1). The review identified two high priority targets in the Walkers Hill gold geochemical trend scheduled for initial Reverse Circulation (RC) drilling to begin in late June. The review also identified multiple untested areas of soil/regolith within prospective parts of the MHCVB that require geochemical infill sampling (Geochemical Gaps) (Figure 2). A 1,600-hole auger program is scheduled to commence in late June 2025 targeting these areas. Figure 1. Talisman’s Lachlan Project which covers the Mineral Hil- Canbelego Volcanic Belt (MHCVB) on a regional TMI Airborne Magnetic image.

Lachlan Project’s southern tenements area with geology and gold-in soil geochemistry. The Walkers Hill geochemical trend (highlighted) is the largest and most coherent soil geochemical anomaly in the area spanning approximately 10km by 2.5km, which contains the Maroonbah and Sheepyard targets. Geochemical gaps across prospective trend of the Mineral Hill - Canbelego Volcanic Belt (MHCVB) are also highlighted. talismanmining.com.au 3 4 August 2024 ASX Announcement Walkers Hill The Walkers Hill geochemical trend, the largest in the district, comprises an extensive gold-in soil anomaly, of approximately 10km by 2.5km of which 5km is within Talisman tenement EL 8571 (see Figure 2 and Figure 3). Several stages of exploration have been undertaken since 2000 by Triako Exploration, Paradigm Resources and Talisman Mining to advance the understanding of this high-priority geochemical trend. Historical exploration results within the Walkers Hill trend include: (See Table 3) • • • 1,250 soils taken at the Sheepyard and Maroonbah Targets between 2003 and 2008. These results show distinct coherent soil anomalies for Au (>20ppb) and As (>150ppm). See Figure 3. RC drilling o 40m at 0.46 g/t Au from 3m (PMV005) and 12m at 0.38g/t Au (TMY027) from surface at Sheepyard (Table 3). o 20m at 0.48 g/t Au from 16m (TBC015) and 5m @ 0.54 g/t Au from 14m (TBC016) at Maroonbah (TBC015) (Table 3). o All mineralised holes ended in oxide and drilling was limited to 60m below surface. Pole Diploe Induced Polarisation (PDIP) geophysical survey completed by Talisman in 2023 revealed a chargeability anomaly below mineralised RC drill intercepts at the Sheepyard target (Figure 4). Talisman will shortly commence RC drilling at the Sheepyard Target. Planned RC drilling will consist of four RC holes up to 200m deep testing the large PDIP anomaly situated below historical anomalous drill intercepts (see Figure 4) including 40m at 0.46g/t Au within the oxide zone of hole PMV005. At completion of the Sheepyard Target drilling, ground geophysical surveying at Maroonbah Target and further reconnaissance of the Walkers Hill geochemical trend will commence with the objective of undertaking further drilling in the September 2025 Quarter. talismanmining.com.au 4 4 August 2024 ASX Announcement Figure 3.

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 worldclass deposits such as Olympic Dam, Carrapateena, and Prominent Hill, as well as recent discoveries including Oak Dam and Emmie Bluff. Figure 9: 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 2024 1, Talisman conducted an initial diamond drilling program in March–April 20252 . 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, 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 Note 1. ASX: TLM -30 October 2024. Note 2. ASX: TLM -28 October 2025. talismanmining.com.au 11 4 August 2024 ASX Announcement (REE) (Table 2). 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.

EL8414 is located within the Company’s Lachlan Project tenure in NSW, sitting between the Carpina North and Noisy Ned prospects (see Figure 1). EL8414 contains several exploration prospects including the Cumbine Prospect. Talisman has been increasing its interest in the project for some time with Peel Mining diluting its ownership. Recently, Peel elected not to contribute funding to the December 2025 half program and has therefore diluted below the 10% ownership threshold. Peel’s interest now reverts to a 1.5% NSR royalty in accordance with the agreement, with Talisman’s ownership increasing to 100%. Management Comment Talisman’s Managing Director, Andrew Munckton, said: "We are excited to be gearing up for a new exploration drilling campaign at the Lachlan Project in NSW to test some newly identified gold targets which represent compelling opportunities for the Company at a very buoyant time in the gold market. These targets were identified by some solid geological work by the team, stemming from a detailed review of geological, geochemical, and geophysical data across the Canbelego Mineral Hill Volcanic Belt. The targets are characterised by a combination of strong geophysics, significant historical drilling results and a lack of modern exploration. The Walkers Hill project contains a large gold-in-soil geochemical anomaly above a significant geophysical IP anomaly. Limited shallow RC drilling at the Sheepyard and Maroonbah prospects shows broad zones of near-surface gold mineralisation up to 40m at 0.46g/t Au in the oxide zone within the gold-in-soil anomaly and above the IP survey anomaly. These features combined, indicate a potentially extensive mineralised system within the Walkers Hill area and represents a stand-out exploration opportunity for the Company. “In addition to testing these gold targets, exploration in NSW is ramping up on other fronts, with the planned auger program across both the Lachlan and Macquarie Arc districts designed to in-fill key geochemical targets within both belts. This will be used to refine and prioritise future RC drilling across emerging target areas. "Meanwhile, the recently completed three-hole diamond drilling program at Mabel Creek intersected zones of alteration associated with granitic intrusions along the interpreted Horse Camp Fault. Hole MCMRD002 returned a broad zone of alteration with anomalous molybdenum (Mo) and rare earth elements (REE). The significance of this anomalism, and its relationship to IOCG-style mineralisation associated with Hiltaba-aged granite intrusions across the Gawler Craton, is currently being investigated through detailed geochemical, geochronological and petrological studies. “Insights from the work to date have led our geological team to focus the IOCG search area to the south of the Horse Camp Fault where several high-priority targets were identified in the 2024 gravity survey. We look forward to progressing this opportunity for the Company in the weeks and months ahead.” –– Ends –– For further information, please contact: Andrew Munckton - Managing Director +61 4 3563 5598 Nicholas Read (Media inquiries) +61 4199 29046 talismanmining.com.au 14 4 August 2024 ASX Announcement 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. The Macquarie Arc Tenements at Yarindury and East Peak Hill include Ordovician Volcanics that regionally host the World Class, Goonumbla, Lake Cowal and Cadia Valley porphyry related Cu-Au deposits. Talisman also has secured access to over 1040 km2 of highly prospective tenure in South Australia’s Gawler Craton at 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 • • • • • • • Talisman Mining’s Mabel Creek diamond core samples, cited in this report, were HQ3 in diameter and were cut either in half or one-third longitudinally using an automated Almonte core saw. Core was held securely in boats during cutting to maintain sample integrity. Sample intervals ranged from 0.3 to 1.3 metres in length, with most samples aligned to 1 metre intervals or adjusted to honour geological contacts. Samples for Rare Earths were collected as one every 5m throughout hole MCMRD001, and every 1m interval throughout hole MCMRD002 and MCMRD003. TLM diamond core sampling is controlled by protocols and QAQC procedures as per industry standard and a chain of custody maintained through transfer to ALS Laboratories in Adelaide, SA. TLM diamond 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 (ME-MS61) and analysis for Rare Earths (MS61L-REE). A 30g 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).
