MELBOURNE, Australia,
March 15, 2022 /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 www.kincoracopper.com

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.

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 announced1, 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.

Table 4: 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
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 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 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.
|
- 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:

|
Geology
|
- Deposit type, geological setting and style of
mineralisation.
|
- 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 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 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.
