MELBOURNE, Australia, Feb. 23, 2022 /CNW/ - Kincora Copper Limited (the Company, Kincora) (TSXV: KCC) (ASX: KCC) is very pleased to provide an exploration update from ongoing drilling at Trundle Park prospect situated at the brownfield Trundle project, located in the Macquarie Arc of the Lachlan Fold Belt (LFB) in NSW, Australia.

"New higher-grade gold-copper system extension confirmed and expanded" - Full press release including Figures and Tables (CNW Group/Kincora Copper Limited)

John Holliday, Technical Committee chair, and Peter Leaman, VP of Exploration, noted:

"While only two holes in, TRDD030 confirms we are onto something of significance in this newly identified southern extension of the mineralized system at Trundle Park and provides increasing confidence of our geological interpretations.

Our working model is that TRDD029 and TRDD030 sit in a down faulted and more mineralised section of the wider system. We are seeing broad zones of multiple chalcopyrite bearing mineralizing events and phases, and the most amounts of visual chalcopyrite to date at the Trundle project.

The intersected skarns zones and vein sets systems have provided important vectors for follow up drilling and are suggestive of very considerable primary source."

Drill hole TRDD030

Hole TRDD030 was collared approximately 685m SSE as a scissor hole testing the up and down dip extent of the Upper skarn zone in TRDD029 and for a causative porphyry intrusion.

As previously announced1, TRDD029 was designed to test the nearer surface intrusions returned in TRDD028 and the southern strike of an emerging mineralised corridor. The hole was continued with newly identified quartz-carbonate-chalcopyrite vein sets increasing with depth before intersecting multiple blind and new broad higher-grade skarn zones.  This was a significant positive development for the project, with these skarn zones exhibiting favourable prograde development, characterised by garnet-magnetite-pyrite, within three notable separate intervals: the Upper Skarn; Middle Skarn; and, Lower Skarn zones, with significant cumulative altered and/or mineralised intervals of some 213m.

Each of these three zones had visible disseminated chalcopyrite associated with the prograde skarn intervals, often with magnetite. garnet and pyrite. Good examples of bladed magnetite were also observed in the prograde skarn assemblages in hole TRDD029.

As previously announced, the assay results for the Upper Skarn zone included 36m @ 0.68 g/t gold and 0.29% copper from 732m with the balance of the hole delivered to ALS Orange and remaining results expected in approximately 2 weeks (impacted by current congestion at the laboratory).  Core for TRDD030 has also been delivered to the lab and is expected in approximately 6 weeks

A second stage of copper development is noticed with bleb-like chalcopyrite occurring in a retro-grade skarn stage with carbonate (both iron-carbonate and calcite) along with orthoclase (orange K-feldspar) and hematite (specular and bladed).  

As anticipated, TRDD030 has provided significant new skarn bedding and true width data, but also positively surprised with the following key developments:

  • Extension of quartz-carbonate-chalcopyrite vein sets: Increased vein sets and visual chalcopyrite where noted over 330m down dip from TRDD029 – see Figure 1 (d) (assays pending). New confirmationary vein orientations have been gained from TRDD030, with a similar NE-trending direction as noted in TRDD029, possibly developed as leakage along fractures emanating from a deeper copper bearing system and providing vectors for follow up drilling.

  • Strike and depth extension of mineralised skarns: The cumulative altered and/or mineralized skarn intervals were extended and totals almost 250m (assays pending) (relative to some 213m in TRDD029). Respective units of the Upper, Middle and Lower Skarns from TRDD029 were intersected in TRDD030. For example, the Middle skarn zone was extended vertically over 100m and over 150m horizontality (at end of zone).

The working interpretation is that TRDD029 and TRDD030 sit in a down faulted, preserved, less faulted and more mineralised section of the wider Trundle Park system.

Multiple chalcopyrite bearing events and phases have been noted with the highest visual chalcopyrite seen to date at the Trundle project. The size of the skarns (very significant in the context of the Macquarie Arc) and vein set systems are suggestive of a significant primary source.

Holes TRDD029 and TRDD030 have provided important geological vectors for follow up. Initial follow up hole TRDD031 has commenced, a 50m step out west of TRDD030, targeting the interpreted up dip potential of the system. TRDD031 will test recently gained skarn bedding, chalcopyrite quartz vein orientation and the core of a magnetic high anomaly.

Air-core drilling commenced

Following completion of annual farming harvests, the return of favourable ground conditions and intrusions being intersected nearer surface in holes TRDD028 and TRDD029 at the Trundle Park prospect, a second rig has commenced a shallow air-core drilling program.

This program will test priority areas of the wider intrusive complex to the north of Trundle Park at the Dunn's and Ravenswood South prospects, located 2km north and 5.5km north-west respectively.  

A planned 54 holes for 2,020 metres is expected to be completed within a month at the Trundle project, following up previous copper -gold geochemistry anomalies.

Shallow near surface drill hole coverage at the majority of the Trundle project is broadly spaced relative to the nature of the narrow but vertically extensive Macquarie Arc porphyry model with many identified geochemical anomalies not sufficiently followed up.

The commenced air-core program seeks to better understand the potential for nearer surface intrusions and extent of identified anomalous copper-gold mineralisation at open pit target depths within these prospect areas.

Table 2: Visual estimates and descriptions of Figure 1 core

In relation to the disclosure of selected intervals of drill core and visual mineralisation, the Company cautions that estimates of sulphide mineral abundance and lithology from preliminary geological logging should not be considered a proxy for quantitative analysis of laboratory assay results or detailed petrology. Assay results are required to determine the actual widths and grade of the visual mineralisation.  Geological logging will be further calibrated with full assay, petrology results and further team review.

Trundle Project background
The Trundle Project is located in the Junee-Narromine volcanic belt of the Macquarie Arc, less than 30km from the mill at the Northparkes mines in a brownfield setting within the westerly rift separated part of the Northparkes Igneous Complex ("NIC"). The NIC hosts a mineral endowment of approximately 24Moz AuEq (at 0.6% Cu and 0.2g/t Au) and is Australia's second largest porphyry mine comprising of 22 discoveries, 9 of which with positive economics.

The Trundle Project includes one single license covering 167km2 and was secured by Kincora in the March 2020 agreement with RareX Limited ("REE" on the ASX). Kincora is the operator, holds a 65% interest in the Trundle Project and is the sole funder until a positive scoping study is delivered at which time a fund or dilute joint venture will be formed.

Drilling, Assaying, Logging and QA/QC Procedures
Sampling and QA/QC procedures are carried out by Kincora Copper Limited, and its contractors, using the Company's protocols as per industry best practise.

All samples have been assayed at ALS Minerals Laboratories, delivered to Orange, NSW, Australia. In addition to internal checks by ALS, the Company incorporates a QA/QC sample protocol utilizing prepared standards and blanks for 5% of all assayed samples.

Diamond drilling was undertaken by DrillIt Consulting Pty Ltd, from Parkes, under the supervision of our field geologists. All drill core was logged to best industry standard by well-trained geologists and Kincora's drill core sampling protocol consisted a collection of samples over all of the logged core.

Sample interval selection was based on geological controls or mineralization or metre intervals, and/or guidance from the Technical Committee provided subsequent to daily drill and logging reports. Sample intervals are cut by the Company and delivered by the Company direct to ALS.

All reported assay results are performed by ALS and widths reported are drill core lengths. There is insufficient drilling data to date to demonstrate continuity of mineralised domains and determine the relationship between mineralization widths and intercept lengths.

True widths are not known at this stage.

Significant mineralised intervals for drilling at the Trundle project are reported based upon two different cut off grade criteria:

  • Interpreted near surface skarn gold and copper intercepts are calculated using a lower cut of 0.20g/t and 0.10% respectively; and,
  • Porphyry intrusion system gold and copper intercepts are calculated using a lower cut of 0.10g/t and 0.05% respectively.

Significant mineralised intervals are reported with dilution on the basis of:

  • Internal dilution is below the aforementioned respective cut off's; and,
  • Dilutions related with core loss as flagged by a "*".

The following assay techniques have been adopted for drilling at the Trundle project:

  • Gold: Au-AA24 (Fire assay), reported.
  • Multiple elements: ME-ICP61 (4 acid digestion with ICP-AES analysis for 33 elements) and ME-MS61 (4 acid digestion with ICP-AES & ICP-MS analysis for 48 elements), the latter report for TRDD001 and former reported for holes TRDD002-TRDD022.
  • Copper oxides and selected intervals with native copper: ME-ICP44 (Aqua regia digestion with ICP-AES analysis) has been assayed, but not reported.
  • Assay results >10g/t gold and/or 1% copper are re-assayed.

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 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
  • Kincora Copper Limited is the operator of the Trundle Project, with drilling using diamond coring methods by DrillIt Consulting Pty Ltd, from which sub-samples were taken over 2 m intervals and pulverised to produce suitable aliquots for fire assay and ICP-MS.
  • Diamond drilling was used to obtain orientated samples from the ground, which was then structurally, geotechnically and geologically logged.
  • Sample interval selection was based on geological controls and mineralization.
  • Sampling was completed to industry standards with 1⁄4 core for PQ and HQ diameter diamond core and 1⁄2 core for NQ diameter diamond core sent to the lab for each sample interval.
  • Samples were assayed via the following methods:
    • Gold: Au-AA24 (Fire assay)
    • Multiple elements: ME-ICP61 (4 acid digestion with ICP-AES analysis for 33 elements) and ME-MS61 (4 acid digestion with ICP-AES & ICP-MS analysis for 48 elements)

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

Geology

  • Deposit type, geological setting and style of mineralisation.
  • All projects ex EL7748 (Condobolin) are within the Macquarie Arc, part of the Lachlan Orogen.
  • Rocks comprise successions of volcano-sedimentary rocks of Ordovician age intruded by suites of subduction arc-related intermediate to felsic intrusions of late Ordovician to early Silurian age.
  • Kincora is exploring for porphyry-style copper and gold mineralisation, copper-gold skarn plus related high sulphidation and epithermal gold systems.

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.
  • Detailed information on Kincora's drilling at Trundle is given in the body of the report.

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.
  • For Kincora drilling at Trundle the following methods were used:
  • Interpreted near-surface skarn gold-copper intercepts were aggregated using a cut-off grade of 0.20 g/t Au and 0.10% Cu respectively.
  • Porphyry gold-copper intercepts were aggregated using a cut-off grade of 0.10 g/t Au and 0.05% Cu respectively.
  • Internal dilution below cut off included was generally less than 25% of the total reported intersection length.
  • Core loss was included as dilution at zero values.
  • Average gold and copper grades calculated as averages weighted to sample lengths.
  • Historic drilling results in other project areas are reported at different cut-off grades depending on the nature of mineralisation.

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 Trundle.
  • 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 Kincora's drilling at Trundle are zones of higher grade within unmineralised 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 Trundle. Other data of interest to further exploration targeting is included in the body of the report.
  • Historic exploration data coverage and results are included in the body of the report for Kincora's other projects.

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.
  • Drilling at the Mordialloc and Trundle Park targets are ongoing at the time of publication of this report and plans for further step-out drilling are in place at both the Trundle Park and Mordialloc prospects. Further drilling is proposed at other Trundle project areas, including air core programs at the Mordialloc, Dunns and Ravenswood South prospects, that have complementary but insufficiently tested geochemistry and geophysical targets with the aim to find: (a) and expand near surface copper-gold skarn mineralization overlying or adjacent to (b) underlying copper-gold porphyry systems.
