Strong Copper-Gold and Base Metal Intercepts Confirm Significant Discovery at Durnings
Thick, high-grade intercepts including 28.3m @ 4.3g/t Au, 0.9% Cu, 3.8% Pb, 0.7% Zn, and 26.5g/t Ag containing massive sulphide zones.
Highlights:
-
Exceptional assay results returned from diamond hole DRRCD0019 , drilled adjacent to the discovery hole DRRCD0006 at the Durnings Prospect , part of the 100%-owned Lachlan Project in NSW. The results confirm two zones of strong, high-grade mineralisation :
-
Base Metals Zone – 25.2 metre zone containing massive, semi-massive, matrix and laminated galena-sphalerite-silver and lesser chalcopyrite-gold from 198.0m downhole. Assays include:
-
7.5m at 1.5% Pb, 2.2% Zn, 23.6g/t Ag, 0.3% Cu, 0.31g/t Au from 198m to 205.5m and
-
7.4m at 6.7% Pb, 2.9% Zn, 137g/t Ag, 0.2% Cu, 0.24g/t Au from 218.8m to 226.2m including:
- 1.7m at 26.5% Pb, 7.8% Zn, 558g/t Ag, 0.7% Cu, 0.81g/t Au from 224.5m to 226.2m containing 1.1m of massive sulphide
-
-
Copper-Gold Zone – 28.3 metre zone containing massive, matrix and blebby chalcopyrite-galena-sphalerite-gold-silver from 370.5m down-hole in an extensively altered quartz-carbonate vein breccia. Assays include:
-
28.3m at 4.03g/t Au, 0.9% Cu, 3.8% Pb, 0.7% Zn, and 26.5g/t Ag from 370.5m to 398.8m down-hole, including:
-
10.0m at 7.94g/t Au, 1.0% Cu, 9.9% Pb, 1.5% Zn and 61.3g/t Ag from 374m to 384m down-hole, including:
-
3.5m at 21.2g/t Au, 1.6% Cu, 11.8% Pb, 2.4% Zn and 84.7g/t Ag from 379.5m down-hole; and
-
7.8m at 4.11g/t Au, 1.8% Cu, 1.0% Pb, 0.6% Zn, and 16.3g/t Ag from 391m to 398.8m .
-
-
-
A total of 13 Stage 2 RC and diamond holes have been completed (DRRC0012 to DRDD0024) with assays awaited.
-
Down-hole electromagnetic (DHEM) surveys underway on DRRCD0019 to identify potential extensions of the high-grade mineralisation.
-
Stage 3 drilling planned to commence shortly to follow-up the high-grade copper-gold and base metals zones once additional assay results and DHEM survey results are returned.
Talisman Mining Limited (ASX: TLM, Talisman ) is pleased to report assay results for the key Reverse Circulation and diamond drill-hole DRRCD0019 completed recently as part of the Stage 2 follow-up drilling program at the Durnings Prospect , part of its 100%-owned Lachlan Project in central NSW.
Significant mineralised zones logged and visually reported in this hole (see ASX announcement 27 March), have now returned strong high-grade base metal assay results (as expected from visual observations of massive, semi-massive and disseminated galena-sphalerite-chalcopyrite) in the Upper Base Metal Zone.
In addition, exceptionally high-grade precious metals assay results have been returned from the Lower Zone of chalcopyrite-galena-sphalerite-quartz-carbonate veins and breccia intersected at depth, confirming the discovery of a significant high-grade copper-gold lens in addition to the base metals.
Collectively, the results show that Durnings is emerging as a significant greenfields base and precious metal discovery , with substantial potential for Talisman’s shareholders.
The immediate focus of follow-up exploration is a down-hole EM (DHEM) survey of DRRCD0019 and DRRCD0006 to determine potential extensions of the high-grade zone. Mineralisation encountered to date should be highly conductive.
Durnings is located approximately 25km north of Condobolin and 35km south-east of the Company’s Rip n Tear discovery within the Lachlan Project area (see Figure 1).
High-grade base metal results were previously reported (see ASX announcements 14 December 2023, 9 January 2024) from Talisman’s initial 1,710m broad-spaced 6-hole RC drilling program (DRRC0006 to DRRC0011), completed in November 2023.

Note 1. Cautionary Statement
Determination of mineralisation has been based on geological logging, visual observation and confirmation using a pXRF machine. No pXRF results are reported however the tool was used to verify the mineralisation. pXRF readings may not be representative of the average concentrations of the elements of interest in a certain volume of material. As such, pXRF results are used as a logging/sampling verification tool only. Laboratory analysis will be required to determine the level of mineralisation contained in the mineralised zones. Visual estimates of mineral abundance or anomalism recorded on pXRF 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.
Geology and Mineralisation
The Durnings prospect is characterised by felsic volcanic rocks of the Mineral Hill Volcanic sequence (MHV). The MHV of Silurian-Devonian age has been mapped within Talisman’s tenure south of Mineral Hill and contains four prospects: Boona, Kaolin Shaft, Hilltop and Durnings in the central part of the sequence.
The MHV package extends to Gunawyle in the north and Brooklyn in the south, a distance of 15km. Underlying the MHV sequence is the Ordovician age Girilambone Formation (See Figure 1).
A series of NW-SE oriented shear zones and faults straddle the sequence and are interpreted as tapping buried Devonian age granite intrusions which outcrop at locations such as Wilmatha and are the source of the heat, fluids and metals for the mineralisation at both Mineral Hill, Durnings and other related prospects in the area.
Results
DRRCD0019
Drilling in DRRCD0019 comprised an RC pre-collar of 100m and HQ diamond core from 100m to 452.9m down-hole. The hole was drilled at 70 degrees towards grid west to intersect the target zone defined by DRRCD0006 at approximately 200m down-hole and the deeper Pole-Dipole Induced Polarisation (PDIP) geophysical target at approximately 350m down-hole (Figure 3).
The deeper zone target is coincident with a broad chargeability model located at approximately 300m below surface from re-processed Pole-Dipole Induced polarisation (PDIP) survey data over the Durnings and Boona areas.
The diamond core in DRRCD0019 intersected two significant zones of sulphide mineralisation containing galena, sphalerite and chalcopyrite in various styles and forms. These include:
-
Base Metals Zone – 198m to 205.5m – 7.5m down-hole (see Figure 4, Table 1, Table 2 and Note 1):
-
Disseminated, blebby, matrix and stringer sulfides (pyrite, pyrrhotite sphalerite, galena, chalcopyrite) within weakly sheared and brecciated carbonate and chlorite altered very fine-grained volcaniclastics.
-
7.5m at 1.5% Pb, 2.2% Zn, 23.6g/t Ag, 0.3% Cu, 0.31g/t Au from 198m to 205.5m

The Company has recently completed the Stage 2 RC and diamond drilling at Durnings comprising 11 RC holes, DRRC0012 to DRRC0022, for 2,306 metres and 10 diamond holes DRRCD0006, DRRCD0008, DRRCD0010, DRRCD0011, DRRCD0015, DRRCD0019, DRRCD0021, DRRCD0022 as diamond tails from RC holes and DRDD0023 and DRDD0024 as diamond holes from surface for a total of 1,614m of core.
These holes were designed to provide an assessment of potential parallel mineralised zones and the strike extent of the Base Metal Zone of mineralisation intersected in DRRCD0006 and DRRCD0019 and the Copper-Gold-Quartz Breccia Zone intersected in DRRCD0019 as reported.
Two additional sections located 80m north and 80m south of the central section have been drilled. See Figure 2 and Table 3 for RC, RCD and DD hole locations.
Several of these holes have intersected various zones of anomalous Pb-Zn-Cu-Sulphide mineralisation as indicated by pXRF field analysis.
Assays for the remaining 10 RC holes and the remaining nine diamond holes are awaited. These samples have been submitted to the assay lab and are expected to be returned in approximately 1 to 3 weeks.
Indicative zones of anomalous zinc sulphide mineralisation, based on pXRF analysis (see Note 1.) in the RC holes within the central section which contains DRRCD0006 and DRRCD0019 are shown on Figure 3.
Next Steps
Structural and geological analysis of the recent drilling is now underway.
Immediate exploration work targeting the high-grade base metal and copper-gold zones has commenced with DHEM surveys currently underway on all diamond holes and selected RC holes to determine if off-hole conductors can be located and modelled.
Subsequent exploration work with additional Stage 3 drilling, immediately along strike and down-dip of the intersection in DRRCD0019 and DRRCD0006 will to be undertaken once assay results are returned for the step-out section holes and DHEM survey results are received, processed and interpreted.
Planning and approval application for Stage 3 drilling is underway with commencement scheduled for the June quarter.
Management Comment
Talisman’s Managing Director, Andrew Munckton, said: “ The Stage 2 drill program at Durnings that intersected impressive visual base metal and copper-gold mineralised intersections has now well and truly delivered with these exceptional assay results – confirming that Durnings is a standout greenfields discovery comprising two distinct zones.
“The Base Metal zone intersected in the original discovery hole DRRCD0006 – which intersected a high-grade zone of 6 metres grading 10.3% Pb, 126g/t Ag, 3.5% Zn, 0.4% Cu and 1.93g/t Au – has now been followed up with DRRCD0019, which is a spectacular hole in every sense!
“DRRCD0019 has intersected two high-grade base metal zones which have matched or exceeded the grades seen in DRRCD0006. This includes a 7.4 metre zone grading 6.7% Pb, 137g/t Ag 2.9% Zn, 0.2% Cu, 0.24g/t Au including a standout high-grade massive and semi-massive sulphide zone of 1.7 metres grading 26.5% Pb, 558g/t Ag, 7.8% Zn, 0.7% Cu, 0.81g/t Au .
“This zone comprises extremely high-value polymetallic mineralization which shows that the highgrade zone intersected in hole DRRCD0006 was definitely not a one-off. This massive sulphide zone now becomes a primary target for follow up exploration.
“In addition, the hole also intersected a highly significant copper-gold rich zone deeper in the hole, which has returned spectacular assays of 28.3m at 4.03g/t Au, 0.9% Cu, 3.8% Pb, 0.7% Zn, and 26.5g/t in a chalcopyrite, gold and disseminated sulphide-rich quartz vein breccia.
“Several sections of this wide intercept returned outstanding high-grade assay results such as 3.5m at 21.2g/t Au, 1.6% Cu, 11.8% Pb, 2.4% Zn and 84.7g/t Ag associated with semi-massive base metal and precious metal sulphides from 379.5m down-hole.
“Both high-grade zones offer huge potential and represent very exciting exploration targets for the Company. In light of this, we recently initiated a program of down-hole EM surveying to search for additional off-hole conductors across the 2.0km strike length of GAIP anomalism tested to date with RC and diamond drilling. Results from the down-hole EM survey program should be available in approximately two weeks.
“Talisman’s geological team have been systematically stepping north and south of the discovery hole line to test the extent of the target zone, aided by the surface GAIP model and the deeper PDIP model developed recently. Geological indicators suggest we have potentially intersected the Base Metal Zone with RC drilling 80m north and 80m south of the discovery line. Assays for these RC holes are awaited.
“Once assay results for the recently completed drilling, down-hole EM and detailed structural analysis of the diamond cores are complete, a further program of Stage 3 follow-up drilling will be planned and commence this quarter.”

Note 1. Cautionary Statement
Determination of mineralisation has been based on geological logging, visual observation and confirmation using a pXRF machine. No pXRF results are reported however the tool was used to verify the mineralisation. pXRF readings may not be representative of the average concentrations of the elements of interest in a certain volume of material. As such, pXRF results are used as a logging/sampling verification tool only. Laboratory analysis will be required to determine the level of mineralisation contained in the mineralised zones. Visual estimates of mineral abundance or anomalism recorded on pXRF 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.
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 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 samples undergo routine 1 metre composite pXRF analysis using an 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. |
| 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 an Evolution FH3000 or UDR1200 truck mounted rig. • The core was orientated using a Reflex Ez-Ori Tool. |
| 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 • 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 relationshipexists between recoveryandgrade |
| Criteria | JORC Code explanation | Commentary |
| • 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. |
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. |
|
| 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 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 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, miningstudies, |

| and metallurgical studies. | ||
| 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 Drilling • 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 samples are dispatched to a sample preparation lab in Adelaide ALS where they are dried, crushed (where required), split and pulverised (total prep) to produce a 0.25g sub sample for base metal analysis or a 50g 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. Diamond Drilling • Diamond drill core (NQ3, HQ or PQ) samples collected for analysis were longitudinally cut in half, and quarters for the QAQC samples using a using an automated Almnonte core saw. Core was placed in boats, holding core in place. • Half core or quarter core sample intervals typically varied from 0.2m 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 are dispatched to a sample preparation lab in Adelaide ALS where they are dried, crushed (where required), split and pulverised (total prep) to produce a 0.25g sub sample for base metal analysis or a 50g 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. |

a maximum of 40% Pb - the upper detection limit of the OG 62h assay method requested from ALS. Two (2) samples both of 0.5m downhole width within the massive sulphide zone (224.5m-226.2m) in DRRCD0019 are affected by this upper limit and have been assigned 40% Pb in the significant intersections grade estimate. • Au analysis by fire assay/AAS Finish (AA24). Over-limit Au by fire-assay and gravimetric finish (GRA-21). • QAQC protocols for all DD sampling involved the use of certified reference materials as assay standards, inserted at a 1 in 25 sampling rate. • Field duplicates and blanks are introduced in areas of identified mineralisation. • 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 1m or 2m composite RC Drill sample undergoes routine pXRF analysis using a Olympus Vanta M-series to aid in logging and identifying zones of interest. All pXRF readings were taken in Geo-Exploration mode with a 45 second 3 beam reading. Standard reference materials were used to calibrate the pXRF instrument every 30 samples. • In relation to the disclosure of visual mineralisation, the Company cautions that visual estimates of sulfide material abundance should never be considered a proxy or substitute for laboratory analysis. Laboratory assay results are required to determine the type, grade and width of the visible mineralisation reported in this announcement. The Company will update the market when laboratory analytical results become available. |
|
| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |

| Orientation of data in relation to geological structure |
• Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• Drill holes are designed to traverse approximately normal to dominant mineralised trends interpreted for each target. • The orientation of key structures may be locally variable and any relationship to mineralisation has yet to be identified. • At this early stage of exploration, drilling and geological knowledge of the project, accurate true widths are yet to be determined. |
| Sample security | • The measures taken to ensure sample security. |

|---|---|---|
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• The Central Lachlan Copper Gold Project currently comprises 15 granted exploration licences: oEL8414 held in joint venture by Haverford (89%participating interest) and Peel Mining Limited (11% participating interest) (Refer Talisman ASX announcement 20 October 2020 for full details); and oEL8547, EL8571, EL8615, EL8677, EL8658,EL8659, EL8680, EL8719, EL9298, EL9299, EL9302, EL9306, EL9315 and EL9379 held 100% by Haverford. • Native Title Claim NC2012/001 has been lodged over the area of the following tenements by NTSCORP Ltd on behalf of the Ngemba, Ngiyampaa, Wangaaypuwan and Wayilwan traditional owners: oEL8414, EL8571, EL8615, EL8677, EL8658,EL8659, EL9298, EL9299, EL9302, EL9306, EL9315 and EL9379. • All tenements are in good standing and there are no existing known impediments to exploration or mining. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• The Lachlan Copper-Gold Project has been subject to exploration by numerous previous explorers. • Exploration work has included diamond, RC and Air Core drilling, ground and down-hole EM surveys, soil sampling, geological interpretation and other geophysics (magnetics, gravity). |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The Lachlan Copper-Gold Project lies within the Central Lachlan Fold belt in NSW. • The Lachlan Copper-Gold Project is considered prospective for epithermal style base-metal and precious metal mineralisation, orogenic mineralisation, and Cobar style base-metal mineralisation. |
| Drill-hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill-holes: • easting and northing of the drill-hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill-hole collar • dip and azimuth of the hole |
• Historical drilling intercepts have been appropriately referenced to source information. • A reference to historic mining grade has been referenced to open file source material. |
| Criteria | JORC Code explanation | Commentary |
| • down hole length and interception depth • 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 intercepts are based on a combination of in-situ at 0.5 g/t Au, or 0.5%Pb, or 0.5% Zn, or 0.2% Cu, or 5g/t Ag cut off grades and ≤ 6m internal dilution. • 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. |
| 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. |
• 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. |
