MELBOURNE, Australia
,
March 21, 2023
/CNW/ - Kincora Copper Limited (ASX: KCC) (TSXV:
KCC) (
Kincora
or
the
Company
) is pleased to provide an exploration update from the new phase
of drilling at the brownfield Trundle project, located in the Macquarie Arc of the Lachlan Fold Belt
(LFB) in NSW,
Australia
.
The drilling is testing 5 shallow large-scale porphyry and porphyry-related skarn targets across the
3.2km strike of the mineralised magnetic complex at the southern portion of the Trundle license.
John Holliday
, Technical Committee chair, and
Peter Leaman
, VP of Exploration, noted:
"Kincora's first three drill holes from the current drill program at Trundle have been very
encouraging, with all having intersected zones of potential ore grade mineralisation at
relatively shallow depths.
The Botfield massive, mineralised magnetite skarn intersection has indicated that the 0.75-
1km long Botfield magnetic high anomaly is likely caused by a large magnetite skarn
body. This is interpreted to be part of a very large porphyry-related copper-gold system.
The magnetic anomaly had not been tested effectively by historic drilling. The Botfield
prospect will be followed up by a priority hole into the core of the magnetic anomaly
250m
further to the east.
We believe the Botfield skarn is the uplifted, nearer surface part of the extensive and well
mineralised skarn system at our previously discovered Southern Extension Zone. Botfield
hole TRDD037 intersected massive magnetite skarn from only 330 metres vertical depth
compared to 710 metres vertical depth in TRDD032 located 430 metres to the west.
Additionally, intersecting porphyry style mineralisation at shallow depths with good grades
at the
Dunn's
North and South prospects, located 640 metres apart, provides significant
encouragement in a new area of exploration. Our understanding of these new prospects
has been greatly improved with gold and porphyry A veins logged at
Dunn's
North and
gold, copper and notably high molybdenum grades at
Dunn's
South. A review of these
prospects, and adjacent open prospects, is ongoing."

Trundle drilling
Kincora's new phase of drilling at the Trundle project commenced in January
1
, and is testing 5
adjacent systems and separate large-scale porphyry targets across an existing 3.2km mineralised
strike – see Figure 1.
Assay results have been returned for Kincora's first holes at the
Dunn's
North and
Dunn's
South
prospects, located
640m
metres apart. These assays have confirmed significant zones of potentially
ore grade porphyry mineralisation at shallow depths – see Tables 1 and 2. Petrology and fertility
analysis is pending with a review commenced of these prospects, and adjacent open prospects, for
follow up exploration.
While assay results are pending for the first hole drilled at the Botfield prospect, notable zones of
visible mineralisation have been prioritized. These include a zone of coarse chalcopyrite-bornite-
pyrite epithermal veins, as well as massive and banded magnetite pyrite-chalcopyrite skarn horizons.
A step out hole from previous shallow intrusive mineralisation at the North-East Gold Zone is in
progress, with a priority follow up hole at the Botfield prospect then planned.
Botfield prospect
Kincora's first hole at the Botfield prospect, TRDD037, sought to test for the first time a large
magnetic high complex coincident with shallow anomalous copper-gold and an IP chargeability high
anomaly.
The concept Kincora sought to test was of a large untested skarn and/or porphyry complex,
potentially associated with the emerging Southern Extension Zone (SEZ) discovery. This discovery
was made by Kincora in the past 18 months to the west, and the southern extension of the multiple
phase intrusive complexes intersected by Kincora and previous explorer drilling.
While assay results are pending, notable zones of visible mineralisation have been prioritized and
include:
Coarse banded chalcopyrite-bornite-pyrite epithermal veins (from 128-
132m
)
Massive magnetite-pyrite-chalcopyrite skarn (>80% magnetite, from 376-
407m
)
Banded magnetite-pyroxene-feldspar skarn with pyrite and chalcopyrite (<30% magnetite from
407-
425m
)
Hole TRDD037 supports the current working interpretation that the Botfield prospect is located in an
uplifted block, in the order of almost
500m
, to the immediately adjacent SEZ prospect across an
interpreted significant N-S fault zone – see Figures 1 and 2.
The relatively shallow chalcopyrite-bornite-pyrite epithermal veins are new to the project, and
support vectors to a more proximal and prospective level in porphyry system - see Photo 1 (a).
Hole TRDD037 intersected over 30 metres of massive magnetite skarn from only 330 metres
vertical depth (see Photo 1 (b)) compared to an interpreted equivalent horizon of 34 metres from
710 metres vertical depth in TRDD032, located 430 metres to the west, with similar stratigraphic
horizons above and below these zones.
The geophysical inversions and targets for TRDD037 correlate well with visual logging and current
interpretations of the returned diamond core, benefiting from the relatively shallow depths and width
of the massive magnetic zone and associated sulphides.
The Botfield prospect has been prioritised for follow up. Planned hole TRDD039 will step out a
further 250 metres to the east testing the up-dip coincident magnetic and induced polarisation (IP)
chargeability anomaly cores, and at potentially open-pitable depths.
Assay results from completed hole TRDD037, and planned TRDD039, will assist in determining the
next phases of drilling at the Botfield and SEZ prospects.

Dunn's
North prospect
Kincora's first hole at the
Dunn's
North prospect, TRDD035, sought to test for the first time the down
dip potential of previous shallow air-core drilling that had failed to test an IP chargeable high
anomaly co-incident with the shoulder of a significant NE-SW trending magnetic anomaly.
Hole TRDD035 confirmed a near surface intrusive complex, intersected early porphyry style quartz
veins (A-type) cutting both diorite(s) and wall-rock volcaniclastic sediments proximal to intrusive
bodies intersected towards the top of the hole, and, the presence of early quartz-chalcopyrite and
quartz-magnetite-chalcopyrite veins at depth.
Encouraging previous gold grades in previous hole PPT08, including
10m
at 1.99 g/t gold and 0.12%
Cu from
36m
, were repeated including
12.5m
@ 2.77g/t gold from
77.5m
, including
2m
@ 14.2g/t
gold, within a near surface gold mineralised diorite-monzodiorite intrusive complex (i.e., from
0m
-
136m
downhole).
Sulphides returned in the intrusive complex, coupled with the subsequently intersected magnetic
andesite volcaniclastic sandstone sequence with interbedded lava follows, towards the west, are
interpreted to have explained the respective IP and magnetic anomalies.

Dunn's
South prospect
Kincora's first hole at the
Dunn's
South prospect, TRDD036, sought to test for the first time a
significant magnetic anomaly, follow up previous broad lower grade mineralisation from surface and
test the up-dip potential a previously intersected felsic intrusions with quartz-carbonate-pyrite veins
with chalcopyrite and bornite.
Hole TRDD036 also confirmed a near surface intrusive complex, intersecting sulphide bearing quartz
veins with encouraging gold and copper grades within the intrusions (eg
44.39m
@ 0.36g/t gold,
0.19% copper and 41ppm molybdenum from only
52.5m
), and zones with high molybdenum grades
(up to 721ppm) associated with intrusions suggesting a proximal setting to a magmatic source.
Highly magnetic hornfels volcanic sandstones intersected subsequent to the intrusive complex
towards the west is interpreted to explain the magnetic anomaly.
The
Dunn's
North and South prospects are located
640m
apart with encouraging but relatively limited
deeper drill hole coverage and are with mineralisation starting from or near surface. Intersecting
porphyry style and potential ore grade mineralisation at shallow depths in holes TRDD035 and
TRDD036, associated with multiple intrusive phases provides encouragement. Fertility and petrology
analysis is ongoing, with a review commenced considering the potential of further drilling towards the
east and along strike towards the north and south (open target areas).

Kincora Copper Limited – NSW drilling program
Following extensive technical reviews, the Company's ongoing drilling program in NSW will seek to
drill test 13 new copper-gold discovery opportunities across 5 projects.
In
January 2023
, drilling commenced at the flagship and brownfield Trundle project seeking to test 5
adjacent system and separate large-scale porphyry targets across an existing 3.2km mineralised
strike and magnetic complex at the southern portion of the Trundle license.
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 intrusive porphyry 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, unless above detection limit where the interval is re-
assayed using fire assay method with atomic-absorption finish (Au-AA26 method of ALS). The
technique allows accurately determine the gold grade above 0.01 g/t and suitable for high –
grade samples where grade exceeds 10 g/t.
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.

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)
unless above
detection limit where the interval is re-assayed
using fire assay method with atomic-absorption
finish (Au-AA26 method of ALS). The technique
allows to accurately determine the gold grade above
0.01 g/t and suitable for high – grade samples
where grade exceeds 10 g/t.
- 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 97.1%, 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.
