Announcement PDF 24 May 2024 Latest Assays Further Expand Rip n Tear Prospect Confirming Large-Scale Base Metal Discovery Highlights: • Assay results received from additional Reverse Circulation (RC) and diamond (DD) drill-holes completed at the Rip n Tear Prospect, part of the 100%-owned Lachlan Project in NSW. • Wide zone of mineralisation intersected in diamond hole MYRCDD0002W, drilled as a wedge from its parent hole to a depth of 407m to test mineralisation down-dip/plunge of the discovery hole MYRCDD0002, which was terminated at 319m due to equipment failure. Results include: MYRCDD0002W • o 156m at 1.3% Pb, 12.6g/t Ag, 0.01% Zn from 148m to 308m, including: o 10m at 7.4% Pb, 59.2g/t Ag, 0.01% Zn from 294m to 304m. Diamond hole MYDD0013 has successfully extended the mineralised horizon ~800m to the east of the discovery hole MYRCDD0003, where it thins significantly but exhibits an increase in zinc grade. Results include: MYDD0013 o • 10.9m at 0.5% Pb, 10.1g/t Ag, 0.54% Zn from 183.1m to 194m Assay results have also been returned for holes MYRC0014 to MYRC0017 at the Southern MLEM Anomaly, which were designed to test below anomalous surface geochemistry. Generally, moderate grade mineralisation was intersected. Results include: o MYRC0014 – 27m at 1.0% Pb, 3.3g/t Ag, 0.02% Zn from 56m o MYRC0015 – 31m at 0.8% Pb, 1.9g/t Ag, 0.01% Zn from 110m o MYRC0016 – 11m at 2.1% Pb, 3.5g/t, Ag, 0.04% Zn from 58m o MYRC0017 – 15m at 1.2% Pb, 1.7g/t Ag, 0.07% Zn from 61m • Continuous lead-silver-zinc mineralisation has now been defined at Rip n Tear over a strike length of more than 2.6km and down-hole widths of up to 200m, highlighting the substantial scale of the mineralised system. • Mineralisation occurs within coarse-grained sandstone and upper parts of a pebble conglomerate sequence. 1 Talisman Mining Limited (ASX: TLM, Talisman) is pleased to report further significant assay results from diamond drilling completed in March and April at the Rip n Tear Prospect, part of its 100%owned Lachlan Project in central NSW. The holes reported in this announcement targeted depth extensions of the broad zones of leadsilver-zinc mineralisation intersected in initial Reverse Circulation (RC) and diamond (DD) drilling. Rip n Tear is located approximately 35km north of Condobolin on EL8615 and approximately 20km north-west of the Company’s Durnings discovery. Both Rip n Tear and Durnings were discovered as part of a 7,200m RC drilling campaign completed in late 2023 within the Lachlan Project area (see Figure 1). Assays have now been received for holes MYRCDD0002W (a diamond extension of a previous RC and diamond drill hole) and MYDD0013 (a diamond drill-hole from surface located along strike of discovery hole MYRCD0003) plus four RC holes MYRC0014 to MYRC0017 testing down-dip of anomalous soil geochemistry, surface rock chips and gossan mineralisation sampled in May 2023. Figure 1 – Lachlan Project location plan highlighting prospect locations along the Canbelego-Mineral Hill Volcanic Belt. 2 Management Comment Talisman’s Managing Director, Andrew Munckton, said: “These latest results from extensional diamond drilling at Rip n Tear provide further encouragement for a major new base metals discovery at this emerging prospect. “These latest results demonstrate the continuity of the lead-silver-zinc mineralised horizon, hosted in a folded and faulted sequence of sediments, over a strike extent of more than 2.6km and downhole widths up to 200m. This clearly demonstrates the significant scale of the discovery. Mineralisation at Rip n Tear appears to be near stratiform mineralization hosted in a coarse and porous sandstone unit. “Importantly, the latest diamond drilling has intersected some zones of higher-grade material of up to 7.4% Pb and 56g/t Ag over a down-hole width of 10m near the base of the mineralized sequence. The geology team are investigating this style of mineralization to confirm its origin and determine the extent and nature of the high-grade zone. This ongoing work will provide detailed geological context to the mineralization, which appears to be extensive, consistent and detectable with geophysics. “It is important to remember that we are still early in the exploration phase at the Rip n Tear Prospect and with detailed geological work there is potential to unlock further high-grade zones within the system”. At Durnings, recent Down Hole Electro-Magnetic (DHEM) surveys have been completed to target potential extensions to high grade sulphide mineralization intersected in drilling reported in late April (See ASX announcement 29 April). DHEM modelling and further assay results for the recently completed diamond drilling program will be reported shortly. Background The Rip N Tear prospect is a large lead-silver-zinc target on EL8615 defined by strongly anomalous base metal soil geochemistry containing two large, coherent, conductive MLEM anomalies (ASX: TLM, 8 May 2023). The initial Talisman program consisted of seven RC holes designed to test the conductive anomalies at depth at approximately 800m to 1,000m drill-hole spacing. Further RC drilling followed by diamond tail extensions resulted in significant intersections (Table 2) (ASX: TLM, 20 October and 6 December 2023). including: • MYRCD0002 – 208m at 1.2% Pb, 8.9g/t Ag, 0.06% Zn from 40m to 248m • MYRCD0003 – 105m at 1.3% Pb, 13.5g/t Ag, 0.09% Zn from 188m to 293m • MYRCD0008 – 26m at 0.5% Pb, 5.2g/t Ag, 0.01% Zn from 152m to 178m • MYRCD0009 – 86m at 0.8% Pb, 6.6g/t Ag and 0.04% Zn from 100m to 186m • MYDD0012 – 87m at 0.5% Pb, 5.3g/t Ag and 0.05% Zn from 261m to 348m This drilling 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. 3 Recent Results Additional drilling of diamond tails from RC holes was completed in March and April on holes MYRCDD0002 and an eastern extension step-out hole MYDD0013 in the north and RC holes MYRC0014 to MYRC0017 in the south of the Rip n Tear Prospect area. All holes intersected further significant zones of mineralisation. Assay results for the recent extensional drilling are summarised in Table 2. Significant results are shown in Figures 3 and 4. The summary of results received to date is listed and includes: Northern Anomaly MYRCD0002W o Diamond Wedge from MYRCD0002 § 156m at 1.26% Pb, 12.6g/t Ag, 0.01% Zn from 148.0m to 304.0m including § 10m at 7.41 %Pb, 59.2g/t Ag, 0.01% Zn from 294m to 394m § 10.9m at 0.5% Pb, 10.1g/t Ag, 0.54% Zn from 183.1m to 194m.

True width of the mineralisation in MYRC0014 and MYRC0015 is approximately 80% of the down-hole 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. The target horizon consists of broad zones of disseminated and blebby sulphides (galena, pyrite, sphalerite and rare chalcopyrite) associated with sericite and ankerite/siderite alteration hosted in sandstone, siltstone and coarse angular quartz breccia/conglomerate. The mineralised horizon appears extensive and consistent over significant strike length and depth as illustrated in Figure 2 and Figure 3. 6 MYRCD0002W intersected a narrow zone of significantly higher-grade mineralisation (10m at 7.4% Pb, 59.2g/t Ag and 0.01% Zn from 294m downhole associated with strong fracturing, quartz veining and short lengths of semi-massive sulphides within a structurally complex inferred fold hinge zone. Thin section and petrographic studies undertaken by Dr Doug Mason of Mason Geoscience have confirmed the host rocks as Sandstones, Layered Siltstones/Mudstones and lesser bioclastic Limestones. Mineralisation exists in all three host rocks but is best developed in the Sandstones, due to their higher porosity with higher grade material present in the Layered Siltstone/Mudstone and fractured parts of all rock types. Infiltration by hydrothermal fluids containing silica-S-Pb-Ag-Zn(-Cu) resulted in pore-filling cements and precipitation of minerals in open fractures and veins. Finer grained Siltstones/Mudstones received preferential mineral precipitation and therefore higher grade due to their carbonaceous mineral content. Rip n Tear – Next Steps Drilling has been completed in the short to medium term while the exploration team focuses on the most recent discovery of high-grade base metals and gold mineralisation at Durnings. Metallurgical test work samples will be submitted for standard flotation and concentrate testwork in the medium term to determine amenability of the mineralisation to processing. Additional test work and geological investigation will be completed on the high-grade zone intersected in MYRCD0002W to confirm the characteristics, orientation and nature of this section of the mineralised horizon.

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.

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. • 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). Commentary • • • • • • • • • 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. RC Drilling samples are collected at either one 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 either 2 metre or 1 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 quarter longitudinally, using an automated Almnonte core saw Core was placed in boats, holding 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 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 50g 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 using an Evolution FH3000 or UDR1200 truck mounted rig. The core was orientated using a Reflex Ez-Ori Tool. 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. No known relationship exists between recovery and grade 11 Criteria JORC Code explanation • Logging • • • 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. Commentary and no known bias exists. Diamond Drilling Core recovery data was 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. 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. RC Drilling 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 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 in the Lachlan Copper-Gold Project. 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. Diamond Drilling • • • • • • • DD logging is carried out on site once geology personnel retrieve core trays from the drill rig site. Core is collected from the rig daily. DD 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 DD drill-holes are logged in full to end of hole. Drillhole collar coordinates, azimuth, dip, depth and sampling intervals are also recorded. DD logging is to geological contacts. DD logging is both qualitative and quantitative depending on the field being logged. Logging of diamond drilling includes geotechnical data, RQD and core recoveries. Drill core is photographed prior to any cutting and/or sampling, and then stored onsite in the Lachlan Copper Gold Project. Photographs are available for every diamond drillhole completed. 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. 12 Criteria Sub-sampling techniques and sample preparation JORC Code explanation • If core, whether cut or sawn and whether quarter, half or whole core taken. Commentary RC Drilling • • 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-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. Diamond Drilling • • • • • • • Quality of ssay data and laboratory tests 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 was collected in a pre-numbered sample bag. 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 was collected in a pre-numbered sample bag. 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. • • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.
