Announcement PDF 26 February 2024 More Wide Lead-Silver Intercepts at Rip n Tear as Scale of Mineralised System Continues to Grow Phase 1 diamond drilling near complete; Drilling to resume at Durnings Highlights: • Assay results received from additional extensional diamond (DD) drill-holes completed recently on EL8615 at the Rip n Tear Prospect, part of the 100%-owned Lachlan Project in NSW. • The diamond extension to MYRCD0002 was designed to test for depth extensions and continuity of mineralisation from previous broad RC drill intercepts which terminated in mineralisation at the northern MLEM anomaly. Diamond drilling wedged from 177.9m down the original 232m deep RC hole. Results include: MYRCD0002 (see ASX: TLM, 20 October 2023) o RC – 192m at 1.3% Pb, 10.1g/t Ag, 0.06% Zn from 40m to 232m end-of-hole o DD wedge – 70.1m at 1.3% Pb, 12.g/t Ag, from 177.9m to 248.0m and - 24m at 0.8% Pb, 9.9g/t Ag, 0.01% Zn from 270.6m to 294.6m o • Combined RC+DD wedge § 208m at 1.2% Pb, 8.9/t Ag, 0.06% Zn from 40m to 248m; and § 24m at 0.8% Pb, 9.9g/t Ag, 0.01% Zn from 270.6m to 294.6m The diamond extension to MYRCD0004 was designed to test for depth extensions and continuity of mineralisation from previous narrow RC intersections within the target horizon and confirm geological continuity of mineralisation at the Southern MLEM anomaly. Diamond drilling extended from the end of the original RC hole at 234m. Results include: MYRCD0004 (see ASX: TLM, 6 December 2023) o RC – 18m at 0.28% Pb, 5.2g/t Ag, 0.01% Zn from 142m to 160m o DD wedge – 59.2m at 0.8% Pb, 1.5g/t Ag, 0.05% Zn from 255m to 314.2m • Extensional diamond drilling has also been completed at MYDD0012, located close to MYRCD0002 and MYDD0013 at the eastern extension of the MLEM survey anomaly, approximately 800m east of MYRCD0003. These holes were designed to target further extensions of the prospective mineralised horizon. Assays are awaited. • The latest results have confirmed the depth extension and continuity of lead-silver-zinc mineralisation at Rip n Tear over a strike length of more than 1.6km and down-hole widths of up to 200m, highlighting the substantial scale of the mineralised system. • The diamond rig will move to complete extensional drilling on RC holes at the Durnings discovery. 1 Talisman Mining Limited (ASX: TLM, Talisman) is pleased to advise that it has received further significant assay results from diamond holes drilled in early 2024 targeting depth extensions of previous broad zones of lead-silver mineralisation intersected in the initial Reverse Circulation (RC) drilling at the Rip n Tear Prospect, part of its 100%-owned Lachlan Project in central NSW. Rip n Tear is located approximately 35km north of Condobolin on EL8615. It lies approximately 20km north-west of the Company’s Durnings discovery, both of which were tested as part of a 7,200m RC drilling campaign completed in late 2023 across four priority prospects within the Lachlan Project area (see Figure 1). Assays have now been received for holes MYRCD0002 and MYRCD0004, diamond drill-hole extensions of the discovery holes MYRC0002 and MYRC0004 completed in December. Figure 1 – Lachlan Project location plan highlighting prospect locations along the Canbelego-Mineral Hill Volcanic Belt. 2 Background The Rip N Tear prospect is an under-explored target on EL8615 defined by strongly anomalous base metal soil geochemistry containing two large, coherent conductive MLEM anomalies (ASX: TLM, 8 May 2023). The prospect is situated within a complex structural setting associated with NNE and NE trending faults which are interpreted to provide a pathway for mineralised fluids from local granite intrusions. Historic drilling was limited to three percussion holes (~61m deep, drilled in 1970’s). The initial Talisman program consisted of seven RC holes designed to test two conductive anomalies at depth at approximately 800m to 1,000m drill-hole spacing. Results from the initial RC drilling (Table 3) (ASX: TLM, 20 October and 6 December, 2023). include: • MYRC0002 – 192m at 1.32% Pb, 10.1g/t Ag, 0.06% Zn from 40m to 232m end-of-hole; • MYRC0003 – 80m at 1.56% Pb, 14.7g/t Ag, 0.11% Zn from 188m to 268m end-of-hole; • MYRC0004 – 18m at 0.28% Pb, 5.2g/t Ag and 0.01% Zn from 142m to 160m; • MYRC0005 – 6m at 0.81% Pb and 5.6g/t Ag from 44m to 50m; • MYRC0006 – 10m at 0.85% Pb, 3.3g/t Ag and 0.02% Zn from 246m to 256m; and • MYRC0007 – 10m at 0.81% Pb, 12.4g/t Ag and 0.04% Zn from 222m to 232m. RC drilling of a further four holes (MYRC008-MYRC0011) for 688m was completed in early December targeting strike extensions of MYRC0002 and MYRC0003, guided by the extensive MLEM anomaly (see Figure 2). Drilled at approximately 500m spacing, these RC holes were designed to target a buried lead-silver and sulphide-rich sedimentary unit which appears to host the mineralisation. RC drilling has intersected broad zones of disseminated galena and silver with accessory sphalerite with strong sulphide mineralisation in sericite and ankerite/siderite altered sedimentary rocks in the target position. As with the previous drilling program, RC drill penetration and sample quality has been reduced by high water inflows at depth and therefore several of the RC holes were suspended in mineralisation or above the targeted mineralised position. Diamond drill tails were completed in December 2023 on RC holes (MYRC0002 and MYRC0003) in the north and (MYRC0004) in the south of Rip n Tear. All holes intersected further significant zones of sulphide mineralisation. Assay results for the recent extensional diamond drilling are summarised in Table 3, detailed in Table 4 and Table 5. Significant results are illustrated in Figure 2 and include: 3 Northern Anomaly MYRCD0002 o o Diamond wedge § 70.1m at 1.31% Pb, 12.0g/t Ag, 0.01% Zn from 177.9m to 248m; and § 24m at 0.80% Pb, 9.9g/t Ag, 0.01% Zn from 270.6m to 294.6m Combining the parent RC hole with the diamond wedge results in: § 208.0m at 1.2% Pb, 8.9g/t Ag, 0.06% Zn from 40m to 248m; and § 24m at 0.80% Pb, 9.9g/t Ag, 0.01% Zn from 270.6m to 294.6m MYRCDD0003 ((ASX: TLM, 30 January 2023) o o Diamond Tail § 41m at 0.3% Pb, 10.4g/t Ag, 0.02% Zn from 272m to 313m, including § 21m at 0.5% Pb, 11.5g/t Ag, 0.02% Zn from 272m to 293m Combining the parent RC hole with the diamond tail results in: § 105.0m at 1.3% Pb, 13.5g/t Ag, 0.09% Zn from 188m to 293m. Southern Anomaly MYRCD0004 o 59.2m at 0.77% Pb, 1.5g/t Ag, 0.05% Zn from 255m to 314.2m 4 Figure 2 – Rip n Tear RC and diamond drilling results over MLEM Geophysical survey image. True width in MYRCDD002 and MYCRDD003 is approximately 40% to 50% of downhole intersection. True with of MYRCDD0004 is approximately 80% of downhole intersection. Geology and Mineralisation The Rip n Tear Prospect is located within EL8615 on the eastern edge of the Canbelego-Mineral Hill Rift Zone (Figure 1), adjacent to a large, controlling, basin margin, NW-SE oriented structure. Devonian-age sediments of the Ewolong Formation (sandstone and conglomerate) and Gwando Siltstone host the prospect. To the west lies the older Ordovician-age Girilambone Group, which is intruded by the early Devonian-age Yellow Mountain Granite. The granite intrusion(s) are interpreted to be the source of heat, fluid and metal for several other lead-silver-zinc and copper-gold deposits and mineralised prospects along the Mineral Hill Rift. Rip N Tear is cut by two NW-SE trending faults interpreted to be transverse faults in a rift setting. Anomalous lead-in-soil geochemistry results, and the coincident MLEM response illustrated in Figures 2, highlight the proximity of the faults to the surface expression of the mineralisation. 5 The target horizon consists of broad zones of disseminated and blebby sulphides (galena, pyrite and rare sphalerite) associated with sericite and ankerite/siderite alteration hosted in sandstone, siltstone and coarse angular quartz breccia/conglomerate. Narrow veins of quartz and galena have also been observed below the thick sedimentary horizon. MYRCDD0002 and MYRCDD0003 are interpreted as being drilled at a moderate angle to the mineralised zones. True width of mineralised zones in these holes are estimated at approximately 40% to 50% of downhole widths. MYDD0012 intersected Girilambone sediments close to surface faulted against mineralised Devonian sediments at depth. A fault zone has been interpreted between the collar positions of MYRCDD0012 and MYRCDD0002. (See Cross Section Figure 3). Rip n Tear – Next Steps The diamond rig has completed hole MYDD0012 (assays pending) located close by MYRC0002 to gather structural and stratigraphic information on the widest part of the mineralised zone. A strong MLEM anomaly extension defined a further 800m east of MYRCDD0003 (our easternmost hole to date) has also been tested with diamond hole MYDD0013 (assays pending) to establish if the mineralisation defined to date continues to the east (see Figure 2). With assays confirming a wider than logged mineralised zone in MYRCDD0004 further sampling of diamond core will be undertaken on this hole to further define the extent and grade of the mineralised zones (Table 4). The diamond drill rig will re-locate to Durnings in the next week to undertake RC hole extension drilling over previously drilled RC holes at that location. Figure 3 – Rip n Tear – Interpreted section (oblique to the interpreted dip and strike) of the Rip n Tear northern MLEM anomaly deposit. True width of mineralisation in MYRCDD0002 is approximately 40% to 50% of downhole intersection. 6 Durnings – Exploration Update Once diamond drilling is complete at Rip n Tear, the rig will mobilise to Durnings to complete diamond drilling tails from three previous RC holes (DRRC0006, DRRC008 and DRRC0010) which terminated in mineralisation. The diamond tails program has been designed to test depth extensions of the mineralised zones. (ASX: TLM 14 December 2023 and 9 January 2024). In addition, follow-up RC drilling will commence in early March, above and immediately along strike from the discovery hole DRRD0006. This step-out RC drilling is designed to provide information on the extent, dip and strike of the high-grade core of the mineralisation. Currently, an auger drilling and soil geochemistry program is underway over the Eastern GAIP Target at Durnings. The program is expected to take approximately three weeks to complete and will guide the initial RC drilling of this large and previously undrilled target during the June Quarter (see Figure 4). Figure 4 – Durnings – RC drill hole locations and Eastern GAIP target over GAIP Geophysical survey image on EL8680. 7 Management Comment Talisman’s Managing Director, Andrew Munckton, said: “We are very encouraged to see more significant assay results being returned from extensional diamond drilling at the Rip n Tear discovery. “These new results demonstrate the continuity of the lead-silver mineralised horizon, hosted in a folded and faulted sequence of sediments, in drilling over a strike extent of more than 1.6km and downhole widths up to 200m. This clearly demonstrates the significant scale of the mineralised system. “The current diamond drilling program is nearing completion with results awaited for several holes aimed at indicating the extent of the mineralisation with diamond tails from RC holes MYRC0008 and MYRC0009 and surface diamond holes MYDD0012 and MYDD0013. If confirmed, this will further extend the mineralisation to a strike length of 2.3km and provide an overall picture of the scale of the opportunity at Rip n Tear. “Importantly, the diamond drilling and multi-element assaying at Rip n Tear provides detailed geological context to the mineralisation – which appears extensive, consistent and detectable with geophysics. “While it is still very early in the exploration phase, the Rip n Tear project so far appears to have all the indicators of an extensive mineralised system in a sedimentary basin setting. “Meanwhile at Durnings, our focus remains on targeting mineralized extensions from the discovery hole at this target, DRRC0006, which identified a sulphide-rich, 6m intersection from 274m downhole, which returned a high-grade assay result of 10.3% Pb, 3.5% Zn 126g/t Ag, 0.4% Cu and 1.93g/t Au. “Step-out RC drilling above and along strike from the original RC intersection in DRRC0006 will provide additional information on the size and direction of the high-grade core to this extensively altered and mineralized position. “Meanwhile, the untested Eastern GAIP target at the Durnings is currently being assessed with auger drilling and soil geochemistry to identify the initial RC drilling locations for follow-up. “Overall, our geologists are looking forward to integrating the geological knowledge derived from the RC and diamond drilling programs with the full assay dataset and the proposed diamond tail drilling program to gain a more accurate picture of the orientation and style of the lead-silver rich horizon at Rip n Tear and the high grade lead-zinc-silver-copper-gold sulphide mineralisation at Durnings. This information will allow us to fully test these extensive structural corridors later in the year.” Ends For further information, please contact: Andrew Munckton - Managing Director on +61 4 3563 5598 Nicholas Read (Media inquiries) on +61 4199 29046 This release has been authorised by the Board of Talisman Mining Limited. 8 Table 1: Drill-hole information summary - Durnings Details and coordinates of the RC holes relevant to this release.

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 1000 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. Mable Creek is surrounded by similar tenure owned and being actively explored by Australia’s biggest resource companies including BHP, Rio Tinto and FMG.

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. • 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).

Measures taken to maximise sample recovery and ensure representative nature of the samples. RC Drilling samples are collected at 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 a Olympus Vanta M-series to aid in logging and identifying zones of interest. Diamond core samples, either PQ, HQ3 or NQ2 in size diameter, were either cut in half longitudinally or a third longitudinally, using an automated Almnonte core saw Core was placed in boats, holding core in place. Core sample intervals varied from 0.3 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 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 30g sub sample was also taken for fire assay for gold with ICP-AES finish 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 was undertaken by DDH1 Drilling Pty LTD ùsing an Evolution FH3000 or UDR1200 truck mounted rig. The core was orientated using a Reflex Ez-Ori Tool.

Diamond drill core (NQ3, HQ or PQ) samples collected for analysis were longitudinally cut in half, and quarters for the QAQC samples using a using an automated Almnonte core saw. Core was placed in boats, holding core in place. Half core or quarter core sample intervals typically varied from 0.3m to 1.3m in length. 1m sample intervals were favoured and are the most common method of sampling, however sample boundaries do principally coincide with geological contacts. The remaining core was retained in core trays.
