Strong Drilling Progress at Central Lachlan Project with Sulphides Intersected at Two Prospects
Visual base metal sulphides encountered at Durnings and Kaolin Shaft, with ongoing RC drilling and generative workstreams continuing across the tenement portfolio
Highlights:
-
Reverse Circulation ( RC ) drilling continues to test a number of priority geophysical targets at Talisman’s Central Lachlan Copper-Gold Project, NSW.
-
Visual base metal sulphides intersected at the Durnings and Kaolin Shaft prospects, reinforcing the prospectivity of the area to host significant VMS-style mineralisation – assays awaited.
-
RC drilling of the Bonzer and Anticline prospects did not indicate a source for the electromagnetic responses returned from the VTEM Max AEM surveys and further work is required.
-
RD drilling is continuing to test a further seven geophysical targets across Exploration Licences EL8414, EL8568 and EL9298.
-
Auger drilling continues with the Walkers Hill/Wirrilah auger program nearing completion, with 191 auger holes drilled and on-site sample analysis using CSIRO developed detectORE™ technology[1] commenced.
-
Ground geophysical surveys are also progressing with survey lines completed over five prospects spanning Exploration Licences EL8571, EL8615, EL9315 and EL9462.
Talisman Mining Ltd (ASX: TLM, Talisman ) is pleased to provide an update on exploration progress at its 100%-owned Lachlan Copper-Gold Project ( Lachlan Project ) in NSW (Appendix 1).
RC Drilling
Reverse Circulation ( RC ) drilling has been completed over five targets on Exploration Licence 8547 ( EL8547 ) and Exploration Licence 8680 ( EL8680 ). These targets were identified on the basis of previous exploration work, electro-magnetic anomalies from Talisman’s 2022 VTEM Max Survey ( AEM ) and magnetic anomalies from previous airborne magnetic surveys. To date, a total of 20 holes for 4,176 metres of RC drilling has been completed by Talisman.
Durnings & Kaolin Shaft Prospects (EL8680)
At the Durnings Prospect, historic exploration drilling in the area identified elevated base metal (copper-zinc-lead) and gold mineralisation, however minimal drilling was conducted to depth. This drilling around the central prospect area included 33 holes to an average depth of 78 metres. The deepest hole in the central prospect was completed in 1970 to a depth of 122 metres and was not

assayed for gold[2] , while other drilling indicated the potential for high-grade mineralisation, with a best result of 4m @ 4.32 g/t Au, 2.24% Cu and 0.27% Zn from 36m in RC hole DUR-1 by Kennecott Exploration in 1985[3] .
The lack of systematic exploration using modern drilling techniques combined with historic intersections of economic grades led Talisman to identify Durnings as an important target for followup. Five RC holes for a combined 1,038m have now been drilled by Talisman at the prospect ( Figure 2, Figure 1, Table 1 and Appendix 1 ), with DRRC0001 targeting an in-fill area within the central Durnings prospect area and extending to depth to assess the potential for mineralisation to 200m. Holes DRRC0002-DRRC0005 inclusive were drilled to test a potential north-east extension of mineralisation along a North-East structural corridor and to follow up on shallow base metal mineralisation encountered in previous drilling.[4] Assays for DRRC0001-DRRC0005 are currently being processed at ALS Laboratories with results expected in May.

In addition, two holes for a total of 444 metres of RC drilling (KSRC0013-KSRC0014) were completed at the Kaolin Shaft prospect ( Figure 1, Table 1 and Appendix 1 ), following up on 2022 drill programs[5] . These holes were designed to target structurally controlled mineralisation thought to be associated with a faulted NW-SE anticline. Finely disseminated sulphides, mainly pyrite, with secondary disseminated sphalerite were logged in the drill chips. Similar results were encountered in distal zones to mineralisation encountered in Talisman’s 2022 drilling program, suggesting that further work is required to determine exploration vectors on structurally controlled polymetallic mineralisation at this prospect.

Base metal sulphides are observed to be sphalerite, galena, chalcopyrite and arsenopyrite. Base metal sulphides were also observed in conjunction with quartz-carbonate veining and minor stockworks in a host rock of volcaniclastics with finely disseminated pyrite, suggesting hydrothermal processes introducing base metals to a volcanogenic massive sulphide ( VMS ) environment.
Additionally, observation of arsenopyrite at the Durnings Prospect suggests the presence of gold mineralisation, as previous holes drilled by Talisman at the Murrays’ Mine and Carpina North prospects[6] have established a relationship between arsenopyrite and gold.
Further, gold mineralisation at the nearby Pearse deposits at the Mineral Hill Mine is known to be associated with a disseminated pyrite-arsenopyrite-stibnite mineral assemblage[7] . The polymetallic nature of the mineralisation intersected is particularly encouraging, as the concurrent intersection of both the copper-gold and lead-zinc-silver mineral systems known to mineralise the Cobar Basin suggests a long-lived structural control in this area acting as a conduit for both phases of mineralising fluids at the Durnings Prospect.
All visual sulphide intercepts for the Kaolin Shaft and Durnings prospects are shown in Table 2. These intercepts are reported and based on visual logging as only semi-quantitative intercepts using geological logging data from sample observations conducted directly at the drill rig. Samples used for logging are scoop samples taken from drill chips at two metre intervals and it must be noted that 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.
Bonzer, Mag High & Anticline Prospects (EL8680 and EL8547)
Six RC drill holes for a total of 1,236 metres (BZRC0001-BZRC0006) ( Figure 1 and Table 1 ) were completed at the Bonzer prospect, targeting AEM features thought to be related to major structures in the area. Additionally, four RC drill holes for a total of 822 metres (ACRC0001-ACRC0004) ( Figure 1 and Table 1 ) were completed at the Anticline prospect targeting a prominent AEM feature. Assay results have been received for both prospects with no significant intercepts returned, however drilling has not indicated nor explained a likely source feature for either electro-magnetic response, suggesting that interpretation of AEM features may require further refinement.
Down-hole electro-magnetic ( DHEM ) surveys are planned on four of these holes to detect potential off-hole conductors which may be the source of the AEM response but missed by drilling. Once DHEM surveys are completed, a re-interpretation of all electro-magnetic data will be conducted to assess the AEM response against drill results and verify target locations and orientations.
Three holes for a total of 636 metres (MHRC0001-MHRC0003) were drilled at the Mag High Prospect ( Figure 1 and Table 1 ), targeting anomalous responses from an airborne magnetic survey. These holes intersected a sequence of felsic tuff and sandstone to the end-of-hole without intersecting magnetic minerals or returning significant magnetic susceptibility results. The magnetic response is inferred to be at depth and additional interpretative work will be conducted to model the response prior to further drilling.

Auger Drilling Program
Auger drilling commenced in March with the commissioning of Talisman’s in-house auger drill rig. This Toyota Landcruiser mounted Eziprobe 1700 drill rig ( Figure 3 ) is capable of drilling to 15 metres, thus providing a better subsurface sample where shallow transported cover sequences may prevent conventional geochemical methods (for example, soil sampling) from being effective.

Figure 3 - Talisman Auger Drill Rig drilling on EL8571
Use of this in-house auger drilling technique will allow Talisman to rapidly assess basement geochemistry across wide areas of shallow cover where other techniques would be much less effective, cost prohibitive and significantly slower.
A total of 191 auger holes have been drilled to date at the Walkers Hill-Wirrilah prospect on EL8571, with daily production increasing as the crew becomes more familiar with ground conditions. Assay results on selected samples from this drilling are currently being processed with results due at the end of May.
– Ground Geophysics Program Electromagnetic & Induced Polarisation Surveys
Talisman’s ground geophysics program is continuing over multiple prospect areas of geological interest where no walk-up drill targets have yet been identified by previous work. Electromagnetic and Induced Polarisation surveys are focused on delineating drill-ready conductive or chargeable anomalies at these prospect areas potentially indicative of base metal sulphide mineralisation. These survey techniques have proven to be key discovery tools in the Cobar Basin.
To date, 272 Pole-Dipole Induced Polarisation (PDIP) stations have been acquired across Exploration Licences EL8615, EL8571, EL9315 and EL9462 and 210 Moving Loop Electro-Magnetic

(MLEM) stations acquired on EL8615. Data is being processed, interpreted and inversions modelled to provide Talisman’s next series of drill ready targets.
Management Comment
Talisman’s CEO, Shaun Vokes, said: “We are making steady progress with systematic RC drill testing of our initial sequence of targets, and we are eagerly awaiting the assay results from the Durnings prospect. The drilling so far has reinforced just how structurally complex the region is, which ultimately is a positive indicator of the potential for a significant discovery.
“Grass roots exploration is an iterative process and we are using the results to date to refine our targeting methodology.
“We have multiple workstreams in progress and the team is working hard to make sure we have a strong pipeline of drill-ready targets across our Lachlan Copper Gold Project for the remainder of the year.”

Cautionary Statement: Talisman notes that these sulphide percentages provided are visual estimates made by qualified geologists on a scoop sample of RC drill chips taken at two metre intervals. These estimates are intended to be indicative only, and the Total Observed Sulphides data is provided as observational ranges of total sulphide content. Appropriate caution should be considered with interpreting this data and visual estimates of sulphide mineral abundances should never be a proxy or substitute for laboratory analyses. Talisman expects that analytical laboratory results will be available for these drillholes in May 2023.

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 a number of 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 a majority participating interest in a joint venture with privately-owned Lucknow Gold Limited in relation to the Lucknow Gold Project (EL6455) in New South Wales. The Lucknow Goldfield was discovered in 1851 and was one of the earliest goldfields to be mined commercially in Australia. Historic production records at the Project are incomplete, however in excess of 400,000 ounces of gold has reportedly been produced at grades of 100 to 200 g/t gold[8] .Very little modern exploration has been completed outside of the existing mine workings and Talisman intends to undertake a program of geochemical surface sampling and mapping at the Project ahead of a drilling program to test for potential down plunge extensions of the high-grade gold ore shoots and repeat structures throughout the Project area.

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 samples are collected at two metre intervals via a drill rig mounted cyclone and static cone splitter set to a 10% split to produce a nominal 4-7kg sample which was collected in a pre-numbered sample bag. • 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 Orange, NSW • RC 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 with ICP- AES finish. • Logging samples were taken via a scoop sample from the 90% reject sample from the cone splitter, sieved to remove the fine fraction and washed to aid visual identification of mineral species. |
| 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 Resolution Drilling Pty Ltd using a UDR650 multipurpose track base-mounted drill rig operating in a Reverse Circulation configuration. 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 150mm size. |
| 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. |
• 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 and no known bias exists. |
13
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| 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. 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 indicative across the intercepted geological units. • Logging samples were taken via a scoop sample from the 90% reject sample from the cone splitter, sieved to remove the fine fraction and washed to aid visual identification of mineral species. • A representative selection of drill chips was retained in PVC chip trays for future use and examination. • RC logging is both qualitative and semi-quantitative depending on the field being logged. • All RC drill-holes are logged in full to end of hole. |
| 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. |
• 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. |
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometres, handheld XRF instruments, etc, the parametres used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
• 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. |

16
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| • hole length. • If the exclusion of this information is justified on the basis that the information is not material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
||
| 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 intersections reported from the Lachlan Copper-Gold Project are based on a nominal 0.25g/t Au, 0.2% Cu, 5g/t Ag, 0.25% Pb or 0.25% Zn cutoff, no more than 5m of internal dilution and a minimum composite grade of 0.25g/t Au, 0.2% Cu, 5g/t Ag, 0.25% Pb or 0.25% Zn. • Cu and Au grades used for calculating significant intersections are uncut. • All results reported in this document have been derived from 2m split samples. • Length weighted intercepts are reported for mineralised intersections. |
| 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 relating to the Lachlan Copper-Gold Project are reported as down hole intersections. True widths of reported mineralisation are not known at this time. |
| 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. |
• Appropriate maps with scale are included within the body of the accompanying document. |
| Balanced reporting |
• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• All relevant data is reported and provides an appropriate representation of the results • The accompanying document is considered to represent a balanced report. |
17
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
