MELBOURNE, Australia ,
March 31,
2022 /CNW/ - Kincora Copper Limited (the Company,
Kincora) (TSXV: KCC) (ASX: KCC) is pleased to provide an
exploration update for drilling activities at the Fairholme
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:
"Our initial five-hole diamond drilling
program at the Gateway prospect has confirmed the mineralised
system, and identified zonation and controls. The system covers a
strike of greater than 600m with the
focus now both to extend the southern trend and finding better
grades, with a nine-hole air-core program planned at
Gateway.
Importantly, the air-core program will also seek
to follow up many geochemical anomalies at other under-explored
prospects across the wider Fairholme project where there is a 16km
mineralised strike along trend from the gold corridor at the Cowal
mine. For example, initial drilling at the Anomaly 2 prospect
is already returning interesting visual results following up a
single previous drill hole interval of 9m @ 1.05 g/t gold and 0.04%
copper.
Many of these anomalies, like Anomaly 2,
have not been drill tested in over 15 years despite hosting
significant existing mineralised footprints, and the significant
resource growth and exploration success at the adjacent Cowal
project."

Fairholme project
The Fairholme project is host to a number of advanced to early
stage exploration prospects across a 16km north-south mineralised
strike, with relatively limited effective previous drilling having
identified multiple and large mineralised systems.
Kincora's initial focus with the completed maiden 5-hole diamond
drill hole program, and recently commenced follow up air-core
program, is the Gateway prospect located less than 15km along
strike from the five epithermal, carbonate base-metal deposits that
comprise the Cowal mine (targeted endowment 15Moz
gold3).
Kincora's diamond drilling is the first program at Fairholme
since Evolution Mining acquired the Cowal project in 2015 and grown
the resource inventory from 3.4Moz gold to 9.6Moz (net of 1.6Moz
mine depletion4). The recently commenced Kincora
air-core program is the first to follow up various shallow
geochemical anomalies since 1997.
Evolution is also undertaking regional exploration outside of
the Cowal mine stating its wider portfolio is a world-class
geologic setting for gold and copper-gold deposits with a number of
large mineralised system footprints on key structures. Kincora's
Fairholme project has various geological similarities to the wider
Cowal mineral systems and mine.
The first phase, five-hole diamond program by Kincora at the
Gateway prospect has identified zonation and controls to
mineralisation, with the prospects system covering over
600m in strike. A second phase and
follow up drilling program, air-core, will seek to both extend the
southern mineralised trend and strike, and test for
higher-grades.
Kincora has been awarded a A$200,000 project drilling grant for the diamond
and air-core drilling programs at the Gateway prospect under the
latest New Frontiers Cooperative Drilling program from the NSW
Government1. The grant follows a competitive expert
panel review process, monies are non-dilutionary and fund direct
per meter drilling costs on a matched dollar-for-dollar basis.

footprints with relatively limited follow up of previous shallow
geochemical anomalies at a number of prospects
A four-hole air-core program has commenced at Anomaly 2 before
moving to complete up to 9-holes at Gateway. Other permitted and
proposed air-core drill prospects listed on right hand side
image.
Diamond core drilling program
Kincora's maiden drilling program at Gateway followed up along a
previously identified NNW structural trend with multiple shallows
to moderate depth, broad width and high-grade gold-copper intervals
from previous drilling (Figures 2 & 3).
Five-holes for 1,684 metres, namely KHFD001 to KFHD005 (Figure
3) has returned broad anomalous copper, gold and base metal
mineralisation, with localised higher-grade zones. The mineral
system at Gateway covers a strike of over 600m, 140m wide and
remains open along strike and at depth (Figure 2).
The program has identified zonation along the NNW-SSE trending
structural corridor, with predominantly gold along the west side,
copper-gold in the central zone and gold-zinc towards the east
(Figure 3). The central zone appears to be favourable for
gold-copper and remains open for further testing towards the SSE
and NNW (Figure 3).
The highest gold grades in the Kincora holes were observed in
KFHD001 with: 1m @ 1.42 g/t gold and
0.03% copper from 47 m downhole (in
saprolite) and 2m @ 0.91 g/t gold and
0.07% copper from 292m down hole
(foliated volcaniclastic sandstone). Anomalous copper grades were
observed to occur close by to diorite intrusions, but hosted mainly
by foliated andesite dominant volcaniclastic siltstones and
sandstones, with some intervals observed with quartz veins
containing pyrite and minor blebs of chalcopyrite.
Notable gold and copper intervals include: KFHD002 with
6m @ 0.15 g/t gold and 0.32% copper
from 196m downhole, and 2m @ 0.20 g/t gold and 0.43% copper from
196m downhole (in foliated
volcaniclastic siltstones), and KFHD005 with 28m @ 0.11 g/t gold and 0.14% copper from
470m, including: 2m @ 0.18 g/t gold and 0.34% copper from
472m, and; 4m @ 0.26 g/t gold and 0.20% copper from
488m downhole (Figure 3). Full
significant intervals are available in Tables 2-6.
Figure 3: Gateway diamond and air-core programs are
looking to confirm and expand a large mineralised
corridor and better understanding the controls of the mineral
system
Air-core drilling commenced
An air-core drilling program at up to six prospects at the
Fairholme project has commenced. The program is following up and
seeking to expand previous geochemical anomalies, often with
coincident geophysical anomalies, at the Anomaly 2, Gateway,
Driftway C, Glencoe, Manna Creek
and Kennel prospects within the Fairholme project.
While there has previously been 552 air-core holes for 46,099
metres drilled at the Fairholme project, there are a number of very
attractive single or multiple point geochemistry anomalies not
followed up – for example at the Anomaly 2 prospect where previous
drilling returned 9m @ 1.05g/t gold
and 0.04% copper from 75m depth
(Figure 2).
Kincora's air-core program is the first since 1997 at many of
these target areas (last air-core drilling by Newcrest Mining) and
drilling is initially taking place at the Anomaly 2 prospect.
Initial visual results of drill hole three of the program
(FHAC003), see Figure 5, are already providing
encouragement.
Following on from the testing of Anomaly 2, a 9-hole program at
the Gateway prospect is seeking to expand the mineralising strike
towards the south (and towards the gold corridor at the Cowal mine)
and test for higher-grade potential, benefiting from the first
phase, 5-hole diamond program completed in 2021. Depending on
ground conditions and access, permits and plans are approved for up
to 28-holes at the prospects outlined in Figure 2.
The ongoing program is analogous to the original Geopeko
reconnaissance RAB drilling to bedrock program over targets,
largely selected on the basis of geophysical data and
insufficiently followed up geochemical data. This program
ultimately led to the discovery of the Cowal gold-base metal
deposits.

Fairholme Project background
The Fairholme Project is located in the southern sector of the
Junee-Narromine Belt of the Macquarie Arc in the Cowal block with
license contiguous to Evolution Mining's flagship Cowal mine and
exploration license portfolio (including the Marsden porphyry deposit, which hosts a 0.56Mt
copper and 1.1Moz gold resource).
The Cowal mine hosts a cluster of epithermal,
quartz-carbonate-base metal-gold mineralisation deposits across a
7.5 x 2km north-south oriented "gold corridor", located on the
western edge of Lake Cowal. In 2015, Evolution Mining acquired the
Cowal mine from Barrick and has since grown gold inventory from
3.4Moz to 9.6Moz (net of 1.7Moz mine depletion), with a target
total endowment of 15Moz Au (noting total historical production of
4Moz gold).
The Fairholme Project includes two contiguous licenses covering
a total of 169.2km2 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 Fairholme 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 Fairholme
project are reported based upon following cut off grade
criteria:
- 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 Fairholme 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 KFHD005.

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 (e.g. submarine nodules) may
warrant disclosure of detailed information
|
- Kincora Copper
Limited is the operator of the Fairholme 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 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)
- Historic sampling
on other projects included soils, rock chips and drilling (aircore,
PCD, 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 Fairholme used diamond core drilling with PQ, and HQ 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,
polycrystalline diamond, 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 93.6%
- Poor recovery zones
are generally associated with thick cover 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.
- Sample sizes are
considered appropriate for the disseminated, generally fine-grained
nature of mineralisation being sampled.
·
|
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.
- Techniques are
considered total for all elements.
- For all holes every
20th sample was either a commercially supplied pulp standard or
pulp blank.
- Results for blanks
and standards are checked upon receipt of assay certificates. All
standards have reported within certified limits of accuracy and
precision.

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 Fairholme 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
Fairholme 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 Fairholme 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 Fairholme 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.

·
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
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 Fairholme 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 Fairholme the following methods were used:
- 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 Fairholme.
- 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 Fairholme 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 Fairholme. 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
Gateway targets are competed at the time of publication of this
report and plans for further step-out drilling are in place at both
the Gateway and Anomaly-2 prospects. Further drilling is proposed
at other Fairholme project areas, including air core programs at
several 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.
