MELBOURNE, Australia, May 2, 2023 /CNW/ - Kincora Copper Limited (TSXV: KCC) (ASX: KCC) (Kincora or the Company) is pleased to announce the commencement of reconnaissance field work by its exploration alliance partner Earth AI Pty Ltd (Earth AI) at the Cundumbul project.

Sam Spring, President & CEO, commented: 

"As Kincora focuses on drill testing our existing 13 copper-gold discovery opportunities within our NSW project pipeline it is pleasing to see Earth AI in the field at the Cundumbul project.

Earth AI has applied its proprietary cloud based AI and machine learning technology to generate targets which are now being field checked by their senior geological team.

This reconnaissance work program will assist confirm and refine target assessment ahead of a planned drilling program utilising their in-house diamond drill rig that is based in Young, NSW.

We are keen to see these targets advance and benefit from Earth AI's proprietary exploration approach which seeks to improve the success rate and lead time to make the discovery of new deposits needed to support the electric vehicle and renewable energy revolutions."   

Cundumbul project

The Cundumbul project is located in the central Molong volcanic belt of the Macquarie Arc within the Lachlan Fold Belt in Central West NSW. The project is approximately 30km south of Alkane's Northern Molong Porphyry project (maiden Boda resource ~10.1Moz AuEq and maiden Kaiser resource ~4.7Moz AuEq), 25km north of Copper Hill (>3Moz AuEq resource) and 70km north of the Cadia mine (>90Moz AuEq endowment) – see Figure 1. Newmont holds the adjacent western and southern license while recent exploration by Sultan Resources immediately east of the license boundary, at multiple common prospect mineral systems, have returned extensive hydrothermal alteration, anomalous copper and gold, and further supported the porphyry potential of the project.

Previous exploration at Cundumbul has included mapping, soil sampling, rock chip sampling, Induced Polarisation (IP), gravity and magnetic geophysical surveying, with more limited follow up auger, RC and diamond drilling.

Mineralised monzonitic intrusions have been identified at both the Bell and Andrews prospects, in the north and south respectively of the project, located over 10km apart – see Figure 2.  

Exploration efforts were last lead by Mitsubishi Materials Corporation during an earn-in period (concluded 2015). The most advanced of the prospects, Bell, was drilled with RC and Diamond methods and intersected high grade molybdenum mineralisation in multiple holes with the best intersection of 4m @ 0.17% molybdenum from 168m (hole CNRC010) in a heavily faulted area with extensive alteration and quartz pyrite veining, phyllic alteration and widespread elevated molybdenum. It is well accepted that porphyry deposits are zoned, and the classic porphyry model had this assemblage setting above the copper bearing source.

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 3 kg 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 (eg submarine nodules) may warrant disclosure of detailed information

  • All Kincora projects have had previous exploration work undertaken by other explorers. The review and verification process for the information disclosed herein and of other parties for the Cundumbul project has included the receipt of all material exploration data, results and sampling procedures of previous operators and review of such information by Kincora's geological staff using standard verification procedures. Further details of exploration efforts and data of other parties are providing in the March 1st, 2021, Independent Technical Report included in the ASX listing prospectus, which is available at: https://www.kincoracopper.com/investors/asx-prospectus
  • Earth AI in April 2023 commenced field work at Cundumbul project under Exploration Alliance Agreement to conduct and jointly fund certain exploration activities on the tenement area.

Geology

 

 

 

  • Deposit type, geological setting and style of mineralisation.

 

 

 

  • The Cundumbul project is located in the Molong belt of the Macquarie Arc, 30km south of Alkane's Boda-Kaiser porphyry projects (maiden resources >14.8Moz AuEq), 25km north of the Copper Hill project (>3Moz AuEq resource) and 70km north of the Cadia mine and series of porphyry deposits (>90Moz AuEq endowment).
  • The projects' geology comprises north-striking fault-bounded slices of Ordovician, Silurian, and Devonian age rocks. Bounding structures are regionally extensive, east-dipping and west-verging thrust faults. One of these thrusts, the Neurea Fault, lies along the western edge of the project and emplaced intermediate volcanics and sediments of the mid-late Ordovician age Oakdale Formation in the east over early Ordovician sediments to the west.
  • Units within the Oakdale formation have been distinguished from detailed mapping and magnetics. Four stratigraphic units are recognised):
  • i. Massive basaltic andesitic volcanolithic conglomerate –debris flow deposits.
  • ii. Interbedded siltstone and fine to medium-grained volcanic sandstone with minor pebble conglomerate: turbidite deposits.
  • iii. Massive polymictic volcanolithic cobble conglomerate, intermediate lavas and allochthonous limestone –debris flow deposits.
  • iv. An upper siltstone and fine to medium-grained volcanolithic sandstone –turbidite deposits distinguished by a high K radiometric response.
  • Historic exploration, through mapping and limited drilling, has defined intrusive rocks associated with mineralised prospects, including monzonite, monzonite porphyry, quartz monzodiorite and granodiorite.
  • Greenfield exploration to date has led to confirmation of a Late Ordovician stratigraphic setting, the presence of porphyritic intrusives and the discovery of high-grade molybdenum, silicification and sulfide veining in a highly faulted setting at the Bell target. There are similar anomalies along the apparent N-S structures to Bell. SRK identified 30 prospective targets across the license, particularly in the north of the license, including the Andrew's target.

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
  • 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.

Mining Associates has completed an review of prior drilling activities at Cundumbul dated February 25th, 2021, as outlined in the Independent Technical Report included in the ASX listing prospectus (dated March 1st, 2021), which is available at:

 

 

 

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.
  • All reported assays have been length-weighted. All intervals are calculated with a 100ppm Mo, 500ppm Mo, 0.1% Mo or 0.1g/t Au cut-off. No upper cut-offs have been applied.
  • Intercepts are length-weighted with no cutting of grades. This may lead to elevation of intercept grades due to the presence of a narrow interval of high grade material. Such high grade zones are reported as included intercepts inside the broader intercept.

 

 

 

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 (eg 'down hole length, true width not known').
  • Due to the uncertainty of mineralisation orientation, the true width of mineralisation is not known at Cundumbul.
  • Intercepts from historic drilling reported at other projects are also of unknown true width.

 

 

 

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.
  • Relevant diagrams are included in the body of the report.

 

 

 

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.
  • Intercepts reported for prior drilling at Cundumbul are zones of higher grade within unmineralized or weakly anomalous material.

 

 

 

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.
  • No other exploration data is considered material to the reporting of results at Cundumbul. Other data of interest to further exploration targeting is included in the body of the report and in Mining Associates Independent Technical Report included in Kincora's ASX listing prospectus (dated March 1st, 2021).

Further work

 

 

 

  • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling).
  • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.
  • Ground truthing field work commenced in April 2023 by Earth AI to confirm and refine drill targets at the Cundumbul project with drilling planned in the next quarter.
  • o Earth AI's work is under the existing success based exploration alliance that seeks to leverage Earth AI's vertically integrated, proprietary artificial intelligence and machine learning capacity to generate, fund and drill test targets.
  • o Earth AI's exploration at the Cundumbul project is in addition to Kincora's ongoing drilling program seeking to drill test a total of 13 copper-gold discovery opportunities across 5 projects in the Lachlan Fold Belt
