Company news release
25 January 2022, 6:00 a.m. EST
  • Ongoing drilling at Kincora's Trundle Park prospect has yielded significant encouragement. Three zones of mineralised skarns have been intersected in most recent hole TRDD029. The cumulative mineralised interval amongst the three units totals some 213m.



  • Assay results are only available for the Upper skarn which has returned 36m @ 1.17 g/t gold equivalent1. Remaining results are due in approximately 5 weeks.



  • Notable mineralised skarn intervals encountered in TRDD029 are:
    • Upper skarn: 36m @ 0.68 g/t gold and 0.29% copper from 732m, including 4m @ 1.19 g/t gold and 0.59% copper (2.19 g/t AuEq1) from 732m
    • Middle skarn: 139.3m intersected between 826.7-966m interpreted to host multiple zones with abundant visual chalcopyrite (assay results pending)
    • Lower skarn: 37.7m intersected between 981.3-1019m (assay results pending)



  • Gold-copper mineralization now confirmed over a ~1.3 km strike and open



  • Follow up hole TRDD030 is ongoing, testing the up and down dip extent of the Upper skarn zone in TRDD029 and for a causative porphyry intrusion



  • Assay results returned for TRDD028 have returned multiple broad lower grade gold zones

MELBOURNE, Australia, Jan. 25, 2022 /CNW/ - Kincora Copper Limited (the Company, Kincora) (TSXV: KCC) (ASX: KCC) is 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.

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

"Hole TRDD029 has returned very encouraging assay and visual results in newly discovered magnetite skarn zones typical of Macquarie Arc porphyry systems. We eagerly await assay results for the remainder of the hole.

TRDD029 opens up a significant search space south, east and west of previous drilling. This hole has further confirmed and expanded a very large mineralised system at Trundle Park that hosts the potential for a cluster of higher-grade skarn and porphyry intrusion bodies.

Despite recent rain, good drilling metres are being achieved. Ongoing hole TRDD030 will provide a better understanding of the new large mineralised zones returned in TRDD029 and coverage of the previously untested southern strike of the currently defined 1.3 km mineralised system at Trundle Park."

An updated corporate presentation, including further details on the Trundle project and recent drill results, is available at www.kincoracopper.com

Drill hole TRDD029

Hole TRDD029 followed up the nearer surface intrusion potential recognized in TRDD028 (latter announced December 6, 2021 release "Porphyry system extended to surface and depth at Trundle Park"). It was also designed to test the western and southern strike for both skarn and porphyry type intrusion mineralisation at depth in a region of very limited deeper drill coverage (one hole) situated across a magnetic low, the eastern shoulder of a moderate magnetic zone and along strike from the existing mineralised corridor at the Trundle Park prospect.

While nearer surface intrusions are observed to occur from surface and continuing westwards, they comprise: (a) micro-diorite (0-31.7m), similar to those also identified in TRDD028, and (b) equi-granular hornblende diorite (31.7-302m) which also includes some shorter intervals with monzodiorite vein dykes (150-275m).

The most significant and positive development from TRDD029 was intersecting multiple blind and new broad higher-grade skarn zones.  These zones exhibit good prograde skarn development, characterised by garnet-magnetite-pyrite, within three notable separate intervals: the Upper Skarn (732-772m); Middle Skarn (826.7-966m); and, Lower Skarn (981.3-1019m) zones.

Importantly, each of these three zones had visible disseminate chalcopyrite associated with the prograde skarn intervals, often with magnetite and pyrite. Good examples of bladed magnetite were also observed in the prograde skarn assemblages.

There is also a second stage of copper development 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). 

The retrograde skarn stages tend to fill in voids (i.e., as matrix fill between breccias) and also along crosscutting veins throughout the earlier prograde skarn stages. The Middle Skarn zone is interpreted to host the more elevated levels of this second stage of copper development relative to the Upper Skarn.

Furthermore, there are examples in hole TRDD029 where chalcopyrite can be observed in both the prograde and retrograde skarn stages, providing at least two identified pulses of fluids with copper bearing sulphides within the skarn. 

Above the skarns and below the aforementioned intrusions, porphyritic andesite lava flows were noted with increasing silicification along with epidote-chlorite-hematite alteration at depth, in-turn cut by later carbonate quartz veins and/or as matrix fill along fractures with chalcopyrite.

Significant assay results so far received for the Upper Skarn zone are included in Table 1 with the core of the Middle, Lower Skarn zones and balance of the hole delivered to ALS Orange, with results expected in approximately 5 weeks (impacted by current congestion at the laboratory).

The last reported quarters' production from Cadia (from Cadia East) mined a head grade of 0.82 g/t gold and 0.35% copper (1.41 g/t AuEq1) with an all in sustaining cost margin of $1,519/oz. This illustrates the favorable economic potential of bulk mining operations in the Macquarie Arc at not dissimilar depths to these mineralised zones in TRDD029. 

Macquarie Arc skarn deposits 

Hole TRDD029 has returned very encouraging assay and visual results in newly discovered magnetite skarn zones typical of Macquarie Arc porphyry systems.

Skarn deposits may be formed peripheral to, and mineralising fluids sourced from, porphyry systems and be represented by strongly altered carbonate and/or volcanic hosts. Skarns deposits can support significant mining operations in their own right but more often associated also with a causative porphyry intrusion and deposit(s).  While no skarn deposits are currently being mined in the Macquarie Arc, historically Big and Little Cadia, two deposits within the Cadia mineral field, were mined very profitably for copper, gold and magnetite, with other smaller similar occurrences having been exploited in the region (including at Kincora's Trundle project). 

The Northparkes mine is currently permitting the E44 gold-copper skarn deposit to be trucked approximately 20km as a first potential satellite operation to its existing porphyry deposits and mill. The E44 deposit is situated south and on the western margin of Northparkes eastern section of the Northparkes Caldera, and potentially in close proximity at the time of mineral deposition to Kincora's Trundle Park prospect before the subsequent rifting of the Junee-Narromine belt and Northparkes Caldera.

From further examples of and ratios between skarn and causative porphyry deposits is included in an updated corporate presentation available at www.kincoracopper.com 

Drill hole TRDD030

Follow up hole TRDD030 has commenced as a scissor hole testing the up and down dip extent of the Upper skarn zone in TRDD029 and for a causative porphyry intrusion.

Despite recent rain, good drilling metres are being achieved and TRDD030 will provide coverage of the previously untested southern strike of the currently defined ∼1.3 km mineralised system at the Trundle Park prospect.

Assay results for the remainder of TRDD029, with further bedding and true width data from TRDD030 will assist the planning for further follow up targeting along with TRDD029, opening up a new significant search space along an identified magnetic and mineralised strike.

Drill hole TRDD028

Previously reported hole TRDD028 intersected nearer surface micro-monzonite and micro-syenite intrusions (as confirmed by petrology) within the first 400m of the hole, and also the presence of a deeper level broad zone of monzodiorite cut by monzonite dykes occurring below skarn. Assay results have returned multiple broad lower grade gold zones – see Table 2.

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)

    - 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
  • Historic sampling on other projects included soils,

    rock chips and drilling (aircore, RAB, RC and

    diamond core).

 

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.).
  • Drilling by Kincora at Trundle used diamond core

    drilling with PQ, HQ and NQ diameter core

    depending on drilling depth.
  • All Kincora core was oriented using a Reflex ACE

    electronic tool.
  • Historic drilling on Kincora projects used a variety

    of methods including aircore, rotary air blast,

    reverse circulation, and diamond core. Methods are

    clearly stated in the body of the previous reports

    with any historic exploration results.

 

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.

 

  • Drill Core recovery was logged.
  • Diamond drill core recoveries are contained in the

    body of the announcement.
  • Core recoveries were recorded by measuring the

    total length of recovered core expressed as a

    proportion of the drilled run length.
  • Core recoveries for most of Kincora's drilling were

    in average over 96.7%, with two holes averaging

    85.0%
  • Poor recovery zones are generally associated with

    later fault zones and the upper oxidised parts of

    drill holes.
  • There is no relationship between core recoveries

    and grades.

 

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.

 

  • All Kincora holes are geologically logged for their

    entire length including lithology, alteration,

    mineralisation (sulphides and oxides), veining and

    structure.
  • Logging is mostly qualitative in nature, with some

    visual estimation of mineral proportions that is

    semi-quantitative. Measurements are taken on

    structures where core is orientated.
  • All core is photographed.
  • Historic drilling was logged with logging mostly

    recorded on paper in reports lodged with the NSW

    Department of Mines.

 

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
  • Once all geological information was extracted from

    the drill core, the sample intervals were cut with an

    Almonte automatic core saw, bagged and delivered

    to the laboratory.
  • This is an appropriate sampling technique for this

    style of mineralization and is the industry standard

    for sampling of diamond drill core.
  • PQ and HQ sub-samples were quarter core and NQ

    half core.
  • Sample sizes are considered appropriate for the

    disseminated,generally fine-grained nature of

    mineralisation being sampled.
  • Duplicate sampling on some native copper bearing

    intervals in TRDD001 was undertaken to determine

    if quarter core samples were representative, with

    results indicating that sampling precision was

    acceptable. No other duplicate samples were taken.

 

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, spectrometers,

    handheld XRF instruments, etc, the

    parameters 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 (ie lack of bias) and

    precision have been established.

 

  • Gold was determined by fire assay and a suite of

    other elements including Cu and Mo by 4-acid

    digest with ICP-AES finish at ALS laboratories in

    Orange and Brisbane. Over-grade Cu (>1%) was

    diluted and re-assayed by AAS.
  • Techniques are considered total for all elements.

    Native copper mineralisation in TRDD001 was

    re-assayed to check for any effects of incomplete

    digestion and no issues were found.
  • For holes up to TRDD007 every 20th sample was

    either a commercially supplied pulp standard or

    pulp blank. After TRDD007 coarse blanks were

    utilised.
  • Results for blanks and standards are checked upon

    receipt of assay certificates. All standards have

    reported within certified limits of accuracy and

    precision.
  • Historic assays on other projects were mostly gold

    by fire assay and other elements by ICP

  • Kincora drilling at Trundle is at an early stage, with

    drill holes stepping out from previous mineralisation

    intercepts at various distances.
  • Data spacing at this stage is insufficient to establish

    the continuity required for a Mineral Resource estimate.
  • No sample compositing was applied to Kincora drilling.
  • Historic drilling on Trundle and other projects was

    completed at various drill hole spacings and no other

    projects have spacing sufficient to establish a

    mineral resource.

 

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.

 

  • The orientation of Kincora drilling at Trundle has

    changed as new information on the orientation of

    mineralisation and structures has become available.
  • The angled drill holes were directed as best possible

    across the known lithological and interpreted

    mineralised structures.
  • There does not appear to be a sampling bias

    introduced by hole orientation in that drilling not

    parallel to mineralised structures.

 

Sample

security

  • The measures taken to ensure sample

    security.

 

 

  • Kincora staff or their contractors oversaw all stages

    of drill core sampling. Bagged samples were placed

    inside polyweave sacks that were zip-tied, stored in

    a locked container and then transported to the

    laboratory by Kincora field personnel.

 

 

Audits or

reviews

  • The results of any audits or reviews of

    sampling techniques and data.

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 materia

    l 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.
