Talisman Mining Limited (ASX: TLM, Talisman ) is pleased to advise that it has received assay results from the remaining Reverse Circulation (RC) holes drilled late last year 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 now been received for RC holes DRRC0006 to DRRC0010, the initial RC holes drilled at Durnings, where a 1,710m broad-spaced 6-hole RC drilling program was completed in late November.

Background
The Durnings Prospect is a lightly explored project defined by strongly anomalous base metal soil geochemistry and contains two large, coherent conductive GAIP anomalies 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 0.27% Pb, 6.3g/t Ag, 0.36% Zn, 0.77% Cu, 6.3g/t Au 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 targeted at the western GAIP anomaly. All six RC holes drilled at approximately 200m spacing were designed to target a buried GAIP anomaly modelled to between 50m and 200m below surface.
RC drilling has intersected two broad zones of disseminated galena, silver, sphalerite, chalcopyrite and gold associated with strong sulphide mineralisation in sericite altered volcaniclastic rocks. Initial results for DRRC0006 and DRRC0007 were reported in mid-December (see ASX announcement 14 December 2023). Recent results include:

10m at 0.4% Pb, 3.9g/t Ag, 0.7% Zn, 0.01% Cu, 0.39g/t Au from 232m to 242m end of hole.
-
Assays for DRRC0011 were submitted to the laboratory approximately 10 days after holes DRRC0008 to DRRC0010 due to wet weather which hampered access to the drill site. Results for this hole are expected within the next two weeks.
-
Three of the six holes (DRRC0006, DRRC0010 and DRRC0011) were suspended in sulphide mineralisation at their various termination depths due to high water inflows. These holes will be extended with diamond core drilling once the diamond drill rig completes its current program at the nearby Rip n Tear prospect.

Geology and Mineralisation
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.
5
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. These sulphide-rich zones correspond with a coherent, conductive GAIP anomaly. See Figure 2 and Figure 4.
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 western 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).
Generally, the geology displays two zones of sulphide mineralisation associated with interpreted NW-SE trending, west dipping faults and geological contacts. The orientation of the mineralised zones is unknown at this time and will be tested with further shallower RC drilling. See Figure 3.
==> picture [503 x 346] intentionally omitted <==
Figure 3 – Durnings geology cross section containing DRRC0006. Note the position of the two identified zones of mineralisation and the high grade core to the Lower Zone. 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
6
The diamond rig is scheduled to mobilise to Durnings to extend DRRC0006, DRRC0010 and DRRC0011 once drilling at Rip n Tear has been completed. Logging of the RC chips and assay results indicates that these holes did not penetrate beyond the altered sulphide-rich zone of interest.
In addition to the current target at Durnings, an extensive additional target located approximately 800m further east of the recent drilling has been identified in the GAIP survey. See Figure 4.
This eastern GAIP anomaly spans approximately 1600m by 250m and is considerably stronger and larger than the western GAIP anomaly that produced the strong recent RC drilling results. The new target will be tested with additional RC drill program to determine the source of the chargeability anomaly. This additional RC drilling program is scheduled to commence in the March quarter 2024.
Additional ground-based GAIP surveys may commence following the testing of the eastern anomaly (subject to encouragement from assay data from DRRC0011 and the additional RC drilling) to investigate if the target horizon extends further south-east beyond the extent of the existing survey area. See Figure 4.

– Rip n Tear Exploration Update
Diamond drilling to extend existing RC holes at Rip n Tear re-commenced on 6 January 2024.
In December 2023, the diamond rig completed extensions in MYRC0002 to 318m (which was terminated in mineralisation due to equipment failure), MYRC0003 to 411m and MYRC0004 to 457m, successfully penetrating the target horizon and underlying unmineralized sediments.
RC drilling was 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. Diamond drilling to extend these RC holes at Rip n Tear is the priority work for the diamond rig over January and February 2024.

– Carpina North and Noisy Ned Exploration Update
RC drilling at both Carpina North and Noisy Ned was completed in November 2023.
No significant assay results were received from either prospect in the 6-hole/1696m RC program completed at Carpina North or the 5-hole/1,580m program completed at Noisy Ned. Both projects remain active exploration opportunities and have both been re-prioritised in light of the exploration results and ongoing work programs at Durnings and Rip n Tear.
Management Comment
Talisman’s Managing Director, Andrew Munckton, said: “ It is exciting to see more significant assay results from the maiden deep holes at the target generated from ground geophysics at Durnings. The better multi-metal assay results are coincident with zones of sulphide mineralization in several of the RC holes drilled into the western GAIP target.
“The mineralisation at Durnings appears to be located in two parallel, west-dipping zones, separated into a Northern Anomaly and a Southern Anomaly by an apparent north-east trending fault. The mineralization is strongly associated with the logged sulphide and sericite altered volcaniclastic rock.
9
“At the Northern Anomaly, while the intersections to date are generally low grade, better grade narrow intersections are also present in the broad-spaced drilling. Further drilling to determine the extent of these higher-grade zones and holes targeted at shallower positions will be undertaken in due course.
“At the Southern Anomaly, the assays for DRRC0011 are awaited. The initial hole at this target, DRRC0006, identified a sulphide-rich, high-grade 6m intersection from 274m down-hole, which returned a significant assay result of 10.3% Pb, 3.5% Zn 126g/t Ag, 0.4% Cu and 1.93g/t Au . The assay results for DRRC0011, located along strike from this hole, will allow us to confirm the continuity of this high-grade mineralized zone.
“A significant additional target at the Durnings prospect has been identified from the GAIP survey. Having confirmed with the first six deep RC holes that the chargeability anomaly is due to base and precious metal-rich sulphide mineralization, the larger and stronger GAIP target located 800m east will now be assessed with an initial RC drilling in a similar fashion to the Durnings target assessment.
“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 March quarter to gain a more accurate picture of the orientation and style of lead-zinc-silver-copper-gold sulphide mineralisation at Durnings and to fully test this extensive structural corridor and emerging mineralised system.”

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.
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.

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. |
• 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. |
| 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). |
• 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 a UDR1200 truck mounted rig. • The core was orientated using a Reflex Ez-Ori Tool. |

presence of Talisman personnel at the drill site. • No known relationship exists between recovery and grade 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 actually 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. Core recoveries averaged >90%, even when difficult ground conditions were being encountered. |
|
| Logging | • 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. • Whether logging is qualitative or quantitative in nature.

RC Drilling • 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 directlyinto laptop |
