Porphyry system further extended at Trundle
Park
Most recent drill hole TRDD014W1 has intersected multiple skarn horizons and broad intervals
of porphyry style intrusions at the Trundle Park prospect (assay results pending);
This hole was a wedge drilling off previous hole TRDD014 and has confirmed previous skarn
intervals and extended the intrusive systems returned in both TRDD014 (
65.5m
@ 0.25 g/t gold
& 0.04% copper, including
10m
@ 0.73 g/t gold & 0.10% copper) and TRDD022 (
162m
@ 0.24
g/t gold & 0.04% copper, including
18m
@ 0.75 g/t gold & 0.09% copper);
A follow up hole (TRDD028) has commenced to the west of TRDD014W1 and south of
TRDD022 to further test the identified mineralized corridor and multiple phase intrusive system
associated with holes TRDD022, TRDD014/W1 and TRDD001 (
21.1m
@ 0.25 g/t gold and
0.03% copper to end of hole);
The direction south from TRDD014/W1 and TRDD028 remains open for future drill testing.

/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:
"The wedge off and extension from TRDD014 has intersected the targeted monzonite
system intruding a larger monzodiorite body with zones of interpreted variable to strongly
developed outer potassic alteration. This setting was generally not apparent in the original
TRDD014 hole and has returned larger interpreted zones of "red" monzonite and
monzodiorite intrusions than TRDD022. TRDD014W1 has provided significant strike and
depth extension from TRDD022, and depth extension from TRDD014.
These are encouraging signs, however, we have still not yet intersected the systems core.
Our drilling has demonstrated a significant size and multiple intrusive system is present
with the features suggestive of being in a proximal environment to a target that offers clear
scale potential. From here, only further systematic drilling will confirm or downgrade this
target.
A recently commenced follow up hole is being drilled west from and parallel to TRDD014,
testing south of TRDD022, and west of both TRDD014W1 and TRDD001. A clear intrusive
porphyry system target zone is emerging at the Trundle Park prospect with the south
remaining open for further drilling."
Two diamond rigs remain operational, one currently drilling TRDD028 at the Trundle Park prospect
at Trundle, and the other completing a fifth hole and final of the first phase diamond drilling program
at the Gateway prospect at the Fairholme project, with assay results from recent drilling pending.

Bespoke March 2020 report by Richard Schodde, MinEx Consulting, for Kincora
Trundle Park prospect
Recent drilling at the Trundle Park prospect has confirmed a significant area and multiple intrusive
porphyry system with a mineralised zone emerging.
Hole TRDD022 returned
162m
@ 0.25 g/t gold, 0.04% copper and 9 ppm molybdenum (from
670m
), including
46m
@ 0.54 g/t gold and 0.08% copper (from
684m
) and
18m
@ 0.75 g/t gold and
0.09% copper (from
712m
) (announced
August 17
th
, 2021:
"Significant gold bearing intervals at
Trundle Park"
). This hole was followed up by TRDD026, a scissor hole expanding the system to the
NNW with two distinct zones of the targeted monzonite intrusion with a larger monzodiorite system
(announced
September 23
rd
, 2021:
"Porphyry system extended at Trundle Park"
).
A wedge drilling off the previous hole TRDD014 (namely TRDD014W1) sought to test the vertical
extent of the main mineralised zone in TRDD022 down dip and on strike to the SSE, and to depth
and horizontally towards the NNW from TRDD014 (
65.5m
@ 0.25 g/t gold and 0.04% copper,
including
10m
@ 0.73 g/t gold and 0.1% copper). While testing the intrusive target at depth under
TRDD022 the wedge and extension (TRDD014W1) has intersected the targeted monzonite vein-
dyke system intruding a larger monzodiorite intrusion with zones of interpreted variable to strongly
developed outer potassic alteration. This setting was generally not apparent in the original TRDD014
hole and has returned larger interpreted zones of "red" monzonite and monzodiorite intrusions than
TRDD022. TRDD014W1 has provided significant strike and depth extension from TRDD022, and
depth extension from TRDD014.
Figure 3:
TRDD022, TRDD026 and TRDD014W1 confirm a multiple phase, multiple intrusive
system with demonstrated mineral tenor, analogous lithology and alteration to the targeted
intrusive porphyry systems that occur elsewhere in the wider and immediate region (at Cadia
and Northparkes respectively)

distance from TRDD028 to TRDD014W1 is approximately
100m
west and

south-west to
TRDD022
From initial logging of TRDD014W1 notable zones include (with assay results pending):
1
.
Upper skarn zone
: cavity filling skarn with early green garnet-pyroxene-magnetite overprinted
by K-feldspar-carbonate-hematite +/- pyrite +/- chalcopyrite from 298-
403.9m
downhole,
hosted by volcanoclastic rocks.
2
.
Lower skarn zone
: massive tan-brown garnet skarn along with some voids filled with prehnite
and carbonate-epidote +/- pyrite, in turn cut by later pyrite veinlets, from 458-
492m
downhole.
3
.
Monzodiorite intrusion
: with albite alteration occurs from 499-
849.5m
downhole, along with
broad intervals containing red quartz monzonite vein dykes and an interval with garnet
endoskarn (see following descriptions for points 4 and 5) and pyrite stringers +/- magnetite also
noted.
4
.
Quartz monzonite vein dykes
: distinctly red, range from >1cm to <100cm in width, and cut
the monzodiorite in two main intervals from 631-
676m
and 718.4-
769m
downhole. Traces of
chalcopyrite along with minor pyrite and quartz were observed as clots and along veinlets in
zones of the quartz monzonite with pyrite stringers +/- magnetite also noted.
5
.
Endoskarn
: comprises a dark brown garnet with magnetite filling voids within the monzodiorite
host rock from 690-
718.4m
. Magnetite alteration is strong and can also occur along fine
fractures and veinlets surrounding garnet.
6
.
Thrust fault then further volcanoclastic sequence
: the interpreted regionally significant
westerly dipping thrust fault (the Tullamore thrust) was intersected in close proximity to the
forecast depth at
849.5m
and defined by sheared red clays to
856m
downhole, along with a
preserved slice of a sheared volcanoclastic sequence +/- pyrite intersected from 856-
876.65m
(end of hole). The latter, indicating the potential for a stacked volcanic and intrusive system.
See Figure 6 for examples of the described rock types in TRDD014W1 with Figures 3 and 4
illustrating the current intrusive model, interpretation and target zone at the Trundle Park prospect.
An illustration of the rocks and alteration in and around the core of the intrusive systems and
deposits at Northparkes are provided in Figure 5.
The multiple phase, multiple intrusive setting returned in TRDD022, TRDD026 and TRDD014W1,
endoskarn intersected in TRDD014W1, coupled with returned mineral tenor in TRDD022, TRDD014
and TRDD001 (
21.1m
@ 0.25 g/t gold and 0.03% copper to EOH), provides indicators of a proximal
environment to the targeted core of an intrusive porphyry system.
The multiple intrusive deposits at the neighbouring Northparkes mine and at Cadia-Ridgeway exhibit
such a setting around discrete mineralized cores of only hundreds of metres in width that are
vertically extensive and occur in clusters or a series of deposits. See Figure 4 for an example of the
working alteration, geological model and target zone of the Trundle Park prospect relative to the E48
deposit at Northparkes.
A follow up hole (TRDD028) has commenced to the west of and parallel to TRDD014W1, and south
of TRDD022 to further test the identified mineralized corridor and targeted core of the system (see
Figures 3 and 4). The direction south from TRDD014/W1 and TRDD028 remains open for future drill
testing.
Figure 4:
The clusters of deposits at the neighbouring Northparkes mine and at Cadia-
Ridgeway exhibit multiple intrusive systems and an alteration, lithology and mineralised
setting not dissimilar to the Trundle Park prospect around discrete mineralized cores of only
hundreds of metres width that are vertically extensive

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 mineralized 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 96.6%, with two holes averaging 85%
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
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 mineralized
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.
