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.

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
-
40m at 0.46 g/t Au from 3m (PMV005) and 12m at 0.38g/t Au (TMY027) from surface at Sheepyard (Table 3).
-
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).
-
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.

Talisman’s initial RC drilling program will test the IP anomaly at depths up to 200m below surface. (For planned drill hole location see Figure 3).
Macquarie Arc Projects, NSW
Yarindury (EL 9679) – Geophysical survey
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 (Figure 5).
Talisman’s planned exploration program over the second half of CY2025 includes a three-line, 13km long, IP (Induced Polarisation) and MT (Magnetotelluric) ground geophysical survey which will commence in July. The survey is targeting prominent magnetic anomalies in the south-eastern portion of the tenement, where historical drilling indicates basement depths of approximately 200m. Drill testing of targets generated from this survey is planned for the September 2025 Quarter (Figure 6).

East Peak Hill (EL 9395) – Auger Drilling
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 150-hole auger survey commenced in May 2025, targeting areas of shallow to moderate cover. Any material copper or gold anomalies identified by the survey will be followed up RC drilling in the SeptemberOctober 2025 period (Figure 8).

Gawler Craton – South Australia
Mabel Creek – June half drilling results
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 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 2025[2] . 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

(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 .

Mount Walton JV – Peel Mining
The Mount Walton JV (MWJV) was formed with Peel Mining over EL8414 in 2017, with Talisman sole funding exploration. 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.”

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 km[2] 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.

Appendix 2
JORC Tables Section 1 & 2
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• 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. |
• 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). • Paradigm Metals RC drilling, cited in this report, provided no specific information on sampling techniques. However, it was noted that samples were submitted for assay as composites over 2m, 3m, 4m, and 6m intervals.Reference: Paradigm Metals Licence 7697 Maroonbah First Annual Report, 2012 (RE0002711). • Western Plains Gold Aircore drilling, cited in this report, provided no specific information on sampling techniques. However, it was noted that variable composites (0.5m to 6m) EOH samples were assayed.Reference: Annual Report for Exploration Licence 6342, Peak Hill East, 2006 (R00054973). • Geopeko RAB drilling cited in this report, provided no specific information on sampling techniques. However, it was noted that selective samples were submitted for assay |

| 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). |
• TLM Mabel Creek MR/Diamond Drilling cited in this report was undertaken by DDH1 Drilling Pty LTD using an Multipurpose UDR1200 truck mounted rig. The core was un-orientated due to vertical holes. • Triako RC drilling, cited in this report, was conducted in 2002 by Geological Ore Services of Cobar using an Edson 300 drill rig mounted on a Toyota 4WD. Compressed air was supplied by a 175 psi / 300 cfm compressor mounted on a trailer towed by the support vehicle. The capacity of the compressor limited drilling depths to between 40 and 60 m.Reference: Triako Third Annual Exploration Report, 2003 (R00048055). • Paradigm Exploration RC drilling, cited in this report, comprised six RC holes (PMV001–PMV006). However, no information was provided regarding the drilling contractor or specific drilling techniques employed.Reference: Paradigm Exploration, Licence 7697 Maroondah First Annual Report, 2012 (RE0002711). • Western Plans Gold Aircore drilling, cited in this report, provided no details on the drilling contractor or equipment used.Reference: Western Plains Gold Annual Report for Exploration Licence 6342, Peak Hill East, 2006 (R00054973). • Geopeko RAB drilling, cited in this report, was carried out by Cherlor; however, no information was provided regarding the drilling equipment used.Reference: Geopeko Peak Hill Parkes Gold Project six monthly Progress Report 1990 (R00004290). |
| 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. |

| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all 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-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. |
• Mabel Creek MR/ DD Processes: •Diamond drill core (HQ) samples collected for analysis were longitudinally cut in half, and quarters for the QAQC samples using a using an automated Almonte 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. •DD 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 DD 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. • Triako RC drilling, cited in this report, involved collecting samples in plastic bags hooked beneath a cyclone mounted on the side of the RC drill rig. Approximately 20 Kg of material was recovered per 1m sample interval. Samples were speared on site and composited into 4 metre intervals for assay. Several individual 1m speared samples were also collected, with assay results generally within a few percent of the corresponding 1 metre riffle split intervals. This suggests that gold distribution is relatively uniform and that the spearing method was adequate for sampling purposes.Reference: Triako Third Annual Exploration Report, 2003 (R00048055). • Paradigm Exploration RC samples, cited in this report, were collected as 2, 3, 4, and 6 m composites using a sample spear.

| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• Significant intercepts are calculated using length weighted average grade calculations for all elements reported. Core loss and intervals not sampled within significant intercepts are excluded from length weighted calculations. • Mabel Creek anomalous drill intercepts using a cut off Mo ≥ 20ppm with ≤ 6m internal dilution (Holes MCMRD001- MCMRD003). TREO has been calculated using: CeO2 + La2O3 + Pr6O11 + Nd2O3 + Sm2O3 + Eu2O3 + Gd2O3 + Tb4O7 + Dy2O3 + Ho2O3 + Er2O3 + Tm2O3 + Lu2O3 + Yb2O3 + Y2O3 (IOGAS: Sugden Geoscience 2023). • Significant intercepts for Triako’s RC drilling at the Sheepyard Target, cited in this report, were recalculated using a 0.2 g/t Au cut-off, allowing for up to 6 metres of internal dilution. |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill-hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
• Drill holes are planned as perpendicular as possible in plan-view to intersect the geological targets. At this early stage of exploration, drilling and geological knowledge of the project accurate true widths are not yet possible as there is insufficient data. • The orientation of key structures may be locally variable and the relationship to mineralisation is yet to be identified. • Drill-holes intersections are reported as down hole widths. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include but not be limited to a plan view of drill-hole collar locations and appropriate sectional views. |
