- 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
.
|
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.
| - Significant intercepts were calculated by Kincora's
geological staff. - No twinned holes have been completed.
- The intercepts have not been verified by
independent personal. - Logging data is captured digitally on electronic
logging tablets and sampling data is captured on paper logs and transcribed to an electronic format into a relational database maintained at Kincora's Mongolian office. Transcribed data is verified by the logging geologist. - Assay data is received from the laboratory in
electronic format and uploaded to the master database. - No adjustments to assay data have been made.
- Outstanding assays are outlined in the body of the
w announcement.
|
Location of data points
| - Accuracy and quality of surveys used
to locate drill holes (collar and down- hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. - Specification of the grid system used.
- Quality and adequacy of topographic
control.
| - Collar positions are set up using a hand-held GPS
and later picked up with a DGPS to less than 10cm horizontal and vertical accuracy. - Drillholes are surveyed downhole every 30m using
an electronic multi-shot magnetic instrument. - Due to the presence of magnetite in some alteration
zones, azimuth readings are occasionally unreliable and magnetic intensity data from the survey tool is used to identify these readings and flag them as such in the database. - Grid system used is the Map Grid of Australia Zone
55, GDA 94 datum. - Topography in the area of Trundle is near-flat and
drill collar elevations provide adequate control
|
Data spacing and distribution
| - Data spacing for reporting of
Exploration Results. - Whether the data spacing and
distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. - Whether sample compositing has
been applied.
| - 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.

| - 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.
