/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
.
John Holliday
, Technical Committee chair, and
Peter Leaman
, VP of Exploration, noted:
"Full assay results for TRDD029 confirm a new geological discovery in the southern
extension zone at Trundle Park, with two encouraging broad intervals of higher gold and
copper tenor in skarn beds typical of Macquarie Arc porphyry copper-gold systems.
Also, most recent hole TRDD031 has added to our understanding of this southern extension
zone. We have now intersected a tabular, bedded, mineralised skarn system across a
strike of over
240m
with Upper, Middle and Lower skarns in three holes. Widths, alteration
and visual mineralisation of these skarn zones are providing vectors for follow up drilling.
These results are very encouraging that we are lateral to and near the margin of the
primary target, the ore discovery we are after, which is a higher-grade, large porphyry
deposit.
As we await assay results for TRDD030 and 31 we continue to systematically explore out
from this new southern extension discovery zone, which remains open in all directions.
Hole TRDD032, a
150m
step-out to the south-east is in progress."
Ahead of the upcoming 121 Mining Investments APAC online conference an updated corporate
presentation, including further details on the Trundle project and recent drill results, is available at

Assay results for drill hole TRDD029 and visuals of TRDD031
Full assay results for hole TRDD029 confirm an important new geological discovery with the
southern extension zone at the Trundle Park prospect. Gold and copper mineralisation was returned
across a total of
196m
covering three separate tabular skarn zones, including higher gold and
copper tenure in the Upper and Middle Skarn zones. This is very encouraging and significant in the
context of the Macquarie Arc. Assay results are included in Tables 1 and 2.

Trundle Park target hole TRDD029 – Summary of skarn zone intervals

Previously reported, January 24th, 2022,
"Newly Discovered Higher-Grade Zones Expand the Large-Scale Gold-Copper System at Trundle Park"
Full summary of significant mineralised intervals from TRDD029 available in Table 2
Most recent hole TRDD031 has intersected the three skarns zones; the Upper, Middle and Lower,
as did TRDD029 and TRDD030, with a cumulative mineralised interval across these skarn zones of
over
100m
. The three holes to date in the southern extension zone have confirmed a tabular,
bedded, multiple zone mineralised skarn system confirmed across over
240m
strike with estimated
true width of up to
120m
(the Middle Skarn in TRDD030). The southern extension zone remains open
in all directions.
Hole TRDD030 intersected cumulative skarns of over
250m
, with quartz-carbonate-chalcopyrite vein
sets in the Middle Skarn with assay results expected in 3 weeks.
Similar to previous holes TRDD029 and TRDD030, there is representation of copper sulphides
associated with prograde skarn development in hole TRDD031. These are generally characterised
by garnet-magnetite-pyrite-chalcopyrite, mainly within the Middle Skarn and also present to a lesser
extent in the Upper Skarn zone (the latter which appears to have pinched out in hole TRDD031).
The width, alteration and visual mineralisation of the respective three skarn zones from hole
TRDD029, TRDD030 and TRDD031 are providing insights to the interpreted fluid pathways from the
primary source, and targeted causative porphyry intrusion.
While TRDD031 didn't intersect the anticipated quartz-carbonate-chalcopyrite vein sets that holes
TRDD029 and TRDD030 did, it returned the first indications of tourmaline occurring along quartz
veinlets along with blebs of bornite and/or chalcopyrite, and from a relatively shallow depth (first
noted at
285m
down hole). This zone was hosted in silica-magnetite altered pebbly volcanoclastic
rocks, and is believed to explain the magnetic high anomaly the hole drilled tested.
At this stage, there are no intersected intrusions identified in TRDD031 to help explain these higher
temperature minerals (tourmaline and bornite) and no deeper intrusions to explain the significant
chalcopyrite and magnetite in the various skarn horizons. This setting of sulphide veining in upper
volcanics supports the working interpretation of targeted causative intrusive source being on a lateral
setting – see Figure 1 for the section and working interpretation of the Trundle Park southern
extension zone.
The skarn zones and quartz sulphide veining in the overlying volcanics from holes TRDD029,
TRDD030 and TRDD031 provide important geological and mineral vectors for the targeted causative
intrusive porphyry source. The large mineralised skarns and vein systems are suggestive of
significant primary source.
Hole TRDD032, a
150m
step-out to the south-east, is in progress following up these vectors, which
are coincident with the wider southern mineralised trend corridor and magnetic low.

Air-core drilling completed
As previously announced
1
, a second rig had been mobilized to complete a shallow air-core drilling
program to 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 total of 50 holes for 1,550 metres with average depths of only 31 metres have been completed.
The program has followed up previous broadly spaced copper-gold geochemistry anomalies.
All holes are interpreted to have inserted basement under shallow post-mineral cover (ranging from
only 1.5 to 84 metres). The program has provided important new end of hole lithology and geological
understanding, interpreted to be similar to the Trundle Park prospect, with prospective alteration,
veining, magnetite and sulphides often noted in the chips and the end of hole samples of core.
Dispatch of samples for assay geochemistry is scheduled for this week with results expected in a
further 8 weeks.
The program is expected to better understand the potential for nearer surface intrusions, skarn
altered zones and the extent of identified anomalous copper-gold mineralisation at open pit target
depths within these prospect areas, where previous drilling has been broadly spaced relative to the
nature of the narrow but vertically extensive Macquarie Arc porphyry model and similar coverage at
Northparkes or Cadia.

Visual estimates and descriptions of Figure 1 core from TRDD031
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 167km
2
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 and Air 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 and some shallow depth Air core drilling.
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 96.9%, 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 and Air core chips are 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
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
