Announcement PDF 14 December 2023 Wide Zone of Strong Lead-Zinc-Silver-Copper-Gold Mineralisation Intersected in RC drilling at Durnings First RC hole in new program hits high-grade base metal and precious metal sulphides Highlights: • Highly encouraging initial assay results received from recent Reverse Circulation (RC) drilling designed to test Gradient Array Induced Polarisation (GAIP) chargeability anomalies at the Durnings Prospect, part of the 100%-owned Lachlan Project in NSW. • Assays have been returned for hole DRRC0006, which intersected two significant zones of disseminated galena (lead) (Pb), silver (Ag), sphalerite (zinc) (Zn), chalcopyrite (copper) (Cu) and gold (Au) in sulphide-rich altered volcanic rocks: DRRC0006 – o 24m at 1.5% Pb, 15.6g/t Ag, 0.2% Zn, 0.02% Cu, 0.04g/t Au from 18m to 42m and; o 40m at 2.4% Pb, 26.3g/t Ag, 1.4% Zn, 0.09% Cu, 0.44g/t Au from 246m to 286m end of hole (eoh) including: ▪ 20m at 3.9% Pb, 45.2g/t Ag, 2.1% Zn, 0.16% Cu and 0.72g/t Au from 260m to 280m ▪ 6m at 10.3% Pb, 126g/t Ag, 3.5% Zn, 0.4% Cu and 1.93g/t Au from 274m to 280m. • The wide mineralised zone intersected from 246m to 286m (end of hole) in DRRC0006 corresponds to a strong GAIP chargeability zone which averages 2.5% sulphur, visually estimated at between 2% and 12% sulphides. • The currently identified GAIP anomaly extends over a strike length of approximately 1.3km. • A total of six RC holes for 1,710m (DRRC0006 to DRRC0011) have been completed at approximately 200m hole spacing as an initial test of this compelling base and precious metal target. Assays for the remaining four holes are awaited. • Five of the six RC holes (DRRC0006, DRRC0008 to DRRC0011) intersected the target zone with significant sulphide mineralisation intersected. • Diamond drilling is planned to further test the GAIP target at depth by extending selected RC holes with diamond core. • An additional ground-based GAIP survey to extend coverage of the prospective chargeable horizons to the south is planned for early 2024, subject to further assay results. 1 Talisman Mining Limited (ASX: TLM, Talisman) is pleased to advise that it has received assay results from the first Reverse Circulation (RC) holes targeting a GAIP geophysical anomaly at the Durnings Prospect, part of its 100%-owned Lachlan Project in central NSW. Durnings is located approximately 15km south-east of Kingston Resources’ Mineral Hill Operations and 25km north of Condobolin. It lies approximately 35km south-east of the Company’s Rip n Tear discovery and is the fourth area to be tested as part of a 7,200m RC drilling campaign recently completed at four priority prospects within the Lachlan Project area (see Figure 1). Assays have so far been received for DRRC0006 and DRRC0007 the first two RC holes drilled at Durnings, where a 1,710m broad-spaced 6-hole RC drilling program was completed in late November. Figure 1 – Lachlan Project location plan highlighting prospect locations along the Canbelego-Mineral Hill Volcanic Belt. 2 Background The Durnings Prospect is a lightly-explored project defined by strongly anomalous base metal soil geochemistry and contains a large, coherent conductive GAIP anomaly located along strike from and to the east of previous RC drilling results returned from earlier exploration by Talisman Mining (see ASX announcement 15 May 2023). The prospect is situated within a complex structural setting associated with NNW trending faults interpreted to be part of the Mineral Hill Fault Zone, which provides a pathway for mineralised fluids to move upwards from deeper local granite intrusions. Historical drilling at the Durnings Project includes Talisman drilling conducted from early 2023 (DRRC0001 to DRRC0005) and previous percussion drilling (KSRC0008 to KSRC0014). See Figure 2 for drill-hole locations. Results from earlier RC drilling include: • DRRC0001 8m at 6.3g/t Au, 0.77% Cu, 0.27% Pb, 0.36% Zn and 6.3g/t Ag from 82m • DRRC0002 12m at 7.72g/t Ag from 74m • DRRC0003 8m at 15.98g/t Ag and 0.15g/t Au from 98m • DRRC0004 14m at 7.14g/t Ag and 0.22g/t Au from 64m • DRRC0005 10m at 5.52g/t Ag from 34m Results RC drilling totalling six holes for 1,710m was completed in late-November. All six RC holes drilled at approximately 200m spacing were designed to target a buried GAIP anomaly modelled to between 50m and 150m below surface. RC drilling intersected two broad zones of disseminated galena, silver, sphalerite, chalcopyrite and gold associated with strong sulphide mineralisation in sericite altered volcaniclastic rocks. Results include: • DRRC0006 – 24m at 1.5% Pb, 15.6g/t Ag, 0.2% Zn, 0.02% Cu, 0.04g/t Au from 18m to 42m and; • DRRC0006 - 40m at 2.4% Pb, 26.3g/t Ag, 1.4% Zn, 0.09% Cu, 0.44g/t Au from 246m to 286m end of hole (eoh) including: o 20m at 3.9% Pb, 45.2g/t Ag, 2.1% Zn, 0.16% Cu and 0.72g/t Au from 260m to 280m o 6m at 10.3% Pb, 126g/t Ag, 3.5% Zn, 0.4% Cu and 1.93g/t Au from 274m to 280m. • DRRC0007 – 8m at 0.5% Pb, 2.1g/t Ag, 1.3% Zn, 0.02% Cu, 0.11g/t Au from 166m to 198m. • Five of the six RC holes (DRRC0006, DRRC0008 to DRRC0011) intersected the target zone with significant sulphide mineralisation intersected. 3 • Two RC holes (DRRC0009 and DRRC0010) terminated in unmineralized laminated sediments after penetrating the target zone. Three of the six holes were suspended in sulphide mineralisation at their various termination depths due to high water inflows. Figure 2 – Durnings RC drilling over GAIP survey image. Geology and Mineralisation 4 The Durnings Prospect is located within EL8680 on the eastern edge of the Canbelego - Mineral Hill Rift Zone (Figure 1), adjacent to the large, controlling, basin margin, NW-SE oriented Mineral Hill Rift controlling structure. Silurian-Devonian age Mineral Hill Volcanics host the prospect. To the east lies the older Ordovicianage Girilambone Group. To the west and northeast Devonian age Talingaboolba Formation sediments overlie or are faulted against the Mineral Hill Volcanics within the Mineral Hill Rift Zone. Broad zones of disseminated and vein hosted sulphides (pyrite, galena, sphalerite, chalcopyrite) are associated with sericite alteration within felsic volcanic and volcaniclastic rock units with porphyritic to fine-grained texture (Figure 3 and 4). These sulphide-rich zones correspond with a coherent, conductive GAIP anomaly. Durnings is cut by a series of NE-SW trending faults interpreted to be relatively small transverse faults in a rift setting. One of these faults is interpreted to cut and displace the GAIP anomaly into two parts, which are the primary targets tested by DRRC0008 to DRRC0010 (in the north) and DRRC0006, DRRC0007 and DRRC0011 (in the south). RC holes DRRC0009 and DRRC0010 terminated in un-mineralised, foliated laminated sediments of the Girilambone Group after penetrating the target zones. 5 Figure 3 – Durnings RC chip trays from DRRC0006 160m to 286m. Zone of strong sulphide mineralisation from 246m to 286m EOH. This 40m wide, sulphide rich zone shows strong base and precious metal mineralisation. Figure 4 – Durnings RC chip tray closeup from DRRC0006, 270m-280m. The 6m section from 274m to 280m shows significant sulphide mineralisation coincident with 10.3% Pb, 3.5% Zn, 126g/t Ag, 0.4% Cu and 1.93g/t Au. Fine sulphide mineralisation is logged throughout the intersection with quartz sulphide breccia logged from 274-280m. Durnings - Next Steps RC drilling has been completed at all four prospects as part of the initial program completed at Rip n Tear, Carpina North, Noisy Ned and Durnings. The RC rig has demobilised from the project areas. Diamond drilling is continuing to extend the mineralised RC holes at Rip n Tear and is due to cease work for the Christmas period on 22 December and return to complete that work from 5 January 2024. The diamond rig is scheduled to mobilise to Durnings to extend DRRC0006 and other RC holes where assay data indicates that hole extension is warranted once the drilling at Rip n Tear has been completed early in January 2024. Durnings RC holes planned for extension include DRRC0006, 6 DRRC0008 and DRRC0011. Logging of the RC chips indicates these holes did not penetrate beyond the altered sulphide-rich zone of interest. Additional ground-based GAIP surveys will also commence in January 2024 (subject to encouragement from assay data presently being processed at the laboratory) to investigate if the target horizon extends south-west beyond the extent of the existing survey area. See Figure 2. Rip n Tear – Exploration Update Diamond drilling to extend existing RC holes at Rip n Tear continues. The diamond rig has completed extension in MYRC0003 to 411m and MYRC0004 to 457m and has successfully penetrated the target horizon and underlying unmineralized sediments in both holes. Diamond drill extension of MYRC0002 is currently in progress. RC drilling has been completed at an additional four holes (MYRC0008 to MYRC0011) at Rip n Tear targeted at the northern MLEM conductor. See Figure 5 for hole locations. These additional RC holes were aimed at intersecting the target horizon at shallow depths and all were drilled with a northerly azimuth. RC holes MYRC0008 to MYRC0011 were generally suspended between 150m to 180m downhole depth due to high water flows. Diamond tails are planned for these recent RC holes, subject to assay results from the RC portion of the hole, when the diamond rig returns to Rip n Tear following the Christmas/New Year break. Cautionary Statement – Visual Estimates Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. 7 Figure 3 – Rip N Tear Additional 4 RC holes MYRC0008 to MYRC0011 locations Management Comment Talisman’s Managing Director, Andrew Munckton, said: “It is very exciting to see the assay results from the first deep holes at a new target generated from ground geophysics at Durnings. The strong multi-metal assay results are coincident with wide zones of sulphide mineralization in DRRC0006, which augurs well for the remaining RC holes drilled into the GAIP target and the potential discovery of a second significant body of mineralization in the current four-prospect drill program. “Our geologists have long been enthusiastic about the potential of this project which, until now, has generated mixed results from limited shallow RC drilling. “Having the financial certainty afforded by our Wonmunna iron ore royalty, combined with a strong balance sheet and a board willing to back a more aggressive exploration approach, has allowed our geological team to shoot for bigger, deeper, stronger targets with higher risk and higher reward drilling. Discoveries like Rip n Tear and now Durnings, are a direct result of this renewed exploration focus. “The mineralisation at Durnings appears to be strongly associated with the logged sulphide and sericite altered volcaniclastic rocks against a westerly dipping fault structure. While the broad zones of mineralization intersected within the GAIP-identified sulphide-rich zone is pleasing, it is the high 8 grade 6m intersection from 274m down-hole in DRRC0006, which grades 10.3% Pb, 3.5% Zn 126g/t Ag, 0.4% Cu and 1.93g/t Au, that has really caught our attention. “Zones like this have the potential to support significant high-grade underground mining operations if sufficient strike and depth extent can be defined with further drilling. Diamond cores from the endof-hole at 286m in DDRC0006 and the assays from the remaining four completed RC holes should be very informative. “Our geologists are looking forward to integrating the knowledge derived from the recently completed RC drilling with the full assay dataset and the proposed diamond tail drilling program in the New Year to gain a more accurate picture of the orientation and style of lead-zinc-silver-copper-gold sulphide mineralisation and to fully test this extensive structural corridor and emerging mineralised system.” 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. 9 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.

From this master pulp, a 0.25g sub sample was taken for multielement 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. 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 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. • 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. • • • Drilling techniques Drill sample recovery Commentary • • 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. • • • 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.

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. 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 duplicates were collected at a 1 in 30 sample rate. QAQC protocols for all RC sampling involved the use of certified reference materials as assay standards, inserted at a 1 in 50 sampling rate. Blank samples were inserted at a 1 in 50 sampling rate using a certified reference material coarse blank. All assays are required to conform to the procedural QAQC guidelines as well as routine laboratory QAQC guidelines. All QAQC controls and measures were routinely reviewed. Laboratory checks (repeats) occurred at a frequency of 1 in 25. Field duplicates returned a reasonable level of precision with some minor variation in Au attributed to nugget effect of gold mineralisation. Each 2m composite RC sample undergoes routine pXRF analysis using a Olympus Vanta M-series to aid in logging and identifying zones of interest.
