MELBOURNE, Australia,
Sept. 23, 2021 /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:
"TRDD026 tested and better
defined the NNW potential from TRDD022 intersecting two zones of
the targeted system, for which assay results are pending. While we
have not yet intersected the systems core we are seeing the
encouraging right signs and are deepening an adjacent hole
(TRDD014W1).
TRDD014W1 seeks to test the
target deeper below TRDD022 and to the SSE, and to
determine if the mineralization in TRDD022 (including
46m @ 0.54 g/t gold and 0.08%
copper) and TRDD014 (including 10m @ 0.73g/t gold and 0.1% copper) are related,
and proximal to the potassic core of the system. Also, we
are planning future holes to test the open direction to the south
of TRDD022 and TRDD014."
Two rigs remain operational, one currently drilling a wedge off
TRDD014 at the Trundle Park prospect at Trundle, and the other has
commenced a fourth hole at the Gateway prospect at the Fairholme
project.
Trundle and Fairholme are both advanced exploration stage
projects with hallmarks of neighbouring deposits, Northparkes and
Cowal respectively, with assay results from recent drilling
pending.

Trundle Park prospect
Recent drilling of hole TRDD022 by Kincora observed significant
broad mineralized intervals comprising 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 16th, 2021: "Significant
gold bearing intervals at Trundle Park"). The results of
TRDD022 revealed a large previously untested zone at depth, open in
all directions. It provided the greatest 'proof of concept' support
to date for Trundle Park to host a porphyry intrusive system,
potentially with ore grades.
Detailed geological logging and petrographic analysis of TRDD022
has noted that the better-mineralized zones are in brecciated
areas, with strongly developed and variable interpreted outer
potassic alteration. These better-mineralized zones exhibit
generally centimetre-scale interpreted fingers of monzonite
vein-dyke and associated mineralization intruding a monzodiorite
intrusion.
TRDD026, the initial diamond drill 'scissor' hole to follow up
TRDD022, sought to test the potential for higher-grade gold-copper
and along strike approximately 100m
NNW from the mineralization zone in TRDD022. TRDD026 has
intersected multiple intrusive phases providing further
confirmation of, and extension to, the targeted porphyry
system.
Figure 3: TRDD022 and TRDD026 provide convincing
and increasing evidence of a multiple phase, multiple intrusive
system with demonstrated mineral tenor with analogous lithology and
alteration to the targeted intrusive porphyry systems that occur
elsewhere in the wider and immediate region (at Cadia and
Northparkes respectively)
(a) Working Leapfrog model – Trundle Park prospect section
(b) Insert with significant mineralised intervals and
illustration of strike/down dip target of TRDD014W1
(c) Plan view of the Trundle Park prospect
TRDD026 intersected the targeted monzonite intrusion in two
zones:
- Within a footwall to a westerly dipping fault where
quartz-monzonite with strong sericite alteration and
quartz-carbonate veining, and breccia fill was observed
(711m to 749m down hole). This interval is visually
interpreted to be similar in mineral composition to the
quartz-monzonite observed in TRDD022 (670m to 730m down
hole) which is potassic altered and along strike towards the south
in relation to TRDD026 (see Figure 5 (b)). The intersection
of the approximately 40m estimated
near true width of the targeted lithological unit
(quartz-monzonite) is encouraging.
- A multiphase felsic intrusion sequence was then intersected
from 746m to 826.9m, interpreted to be representative of the
true width of this unit of the system (eg approximately
80m). This zone is dominated by
monzodiorite, with interpreted later intrusions of minor quartz
monzonite exhibiting patchy potassic alteration and also quartz
monzodiorite with chlorite-silica alteration.
The potassic altered quartz monzonite, with chalcopyrite
mineralization (see Figure 5(d)), in TRDD026 at 750m down hole depth appears similar to and is
interpreted to be related to the potassic altered quartz monzonite
in hole TRDD022 at 715m depth
containing elevated gold and copper. Importantly, this
interpretation supports potassic alteration occurring approximately
100m along strike and to the north of
TRDD022.
See Figure 5 for examples of rock types in TRDD026 and
interpreted equivalent units to TRDD022 with Figures 3 and 4
illustrating the current intrusive model and interpretation at the
Trundle Park prospect.
The multiple phase, multiple intrusive setting returned in
TRDD022 and TRDD026, coupled with returned mineral tenor in TRDD022
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 width that are vertically extensive and occur in clusters
or a series of deposits. See Figure 4 for an example of the working
alteration and geological model of the Trundle Park prospect
relative to the E48 deposit at Northparkes.
A wedge drilling off the previous hole TRDD014 has commenced.
This hole TRDD014W1 is seeking to test the vertical extent of the
main mineralized zone in TRDD022 (46m
@ 0.54 g/t gold and 0.08% copper) down dip and on strike to the
SSE, and horizontally to the NNW from TRDD014 (10m @ 0.73g/t gold and 0.1% copper). Importantly,
TRDD014W1 seeks to determine the potential for the mineralization
in these two holes to be related, and proximal to the potassic core
of the currently defined intrusive system.
Figure 4: Interpreted structurally controlled
sericitic overprinting alteration phase intersected in TRDD026
adjacent to potassic alteration in TRDD022 supports a further
potential mineralising event within the porphyry system at Trundle
Park
- Pervasive fault/fracture controlled sericitic alteration often
occurs in the centre of Northparkes/Goonumbla district mineralised
systems and extends to depth
While sericitic alteration in the traditional porphyry model is
generally associated to be located in a higher level in the system,
deep-level sericite alteration often occurs overprinting or
adjacent to the core of the E48, E26, E27 and E22 porphyry deposits
and E44 skarn deposit at the neighbouring Northparkes system.

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.

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 97%, 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.
|
- Mining Associates has completed an review of sampling
techniques and procedures dated January 31st, 2021, as outlined in
the Independent Technical Report included in the ASX listing
prospectus, which is available at:

Exploration
done by
other parties
|
- Acknowledgment and appraisal of exploration by other
parties.
|
- All Kincora
projects have had previous exploration work undertaken.
- The review and
verification process for the information disclosed herein and of
other parties for the Trundle project has included the receipt of
all material exploration data, results and sampling procedures of
previous operators and review of such information by Kincora's
geological staff using standard verification procedures. Further
details of exploration efforts and data of other parties are
providing in the March 1st, 2021, Independent Technical
Report included in the ASX listing prospectus, which is available

Geology
|
- Deposit type, geological setting and style of
mineralisation.
|
- All projects 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 material 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 unmineralized 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. Further drilling is
proposed at other Trundle project areas 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.
