MELBOURNE, Australia, March 21, 2023 /CNW/ - Kincora Copper
Limited (ASX: KCC) (TSXV: KCC) (Kincora or the
Company) is pleased to provide an exploration update from
the new phase of drilling at the brownfield Trundle project,
located in the Macquarie Arc of the Lachlan Fold Belt (LFB) in NSW,
Australia.
The drilling is testing 5 shallow large-scale porphyry and
porphyry-related skarn targets across the 3.2km strike of the
mineralised magnetic complex at the southern portion of the Trundle
license.
John Holliday, Technical
Committee chair, and Peter Leaman,
VP of Exploration, noted:
"Kincora's first three drill holes from the
current drill program at Trundle have been very encouraging, with
all having intersected zones of potential ore grade mineralisation
at relatively shallow depths.
The Botfield massive, mineralised magnetite
skarn intersection has indicated that the 0.75-1km long Botfield
magnetic high anomaly is likely caused by a large magnetite skarn
body. This is interpreted to be part of a very large
porphyry-related copper-gold system. The magnetic anomaly had not
been tested effectively by historic drilling. The Botfield prospect
will be followed up by a priority hole into the core of the
magnetic anomaly 250m further to the
east.
We believe the Botfield skarn is the
uplifted, nearer surface part of the extensive and well mineralised
skarn system at our previously discovered Southern Extension Zone.
Botfield hole TRDD037 intersected massive magnetite skarn from only
330 metres vertical depth compared to 710 metres vertical depth in
TRDD032 located 430 metres to the west.
Additionally, intersecting porphyry style
mineralisation at shallow depths with good grades at the
Dunn's North and South prospects,
located 640 metres apart, provides significant encouragement in a
new area of exploration. Our understanding of these new prospects
has been greatly improved with gold and porphyry A veins logged at
Dunn's North and gold, copper and
notably high molybdenum grades at Dunn's South. A review of these prospects, and
adjacent open prospects, is ongoing."
Figure 1: Kincora's ongoing phase of drilling at the Trundle
project is testing 5 adjacent system targets across a 3.2km
mineralised and magnetic system complex (Dunn's North, Dunn's South, NE-Gold Zone, Botfield and the
Southern Extension Zone (SEZ)). Neighbouring explorer drilling is
testing the western and southern extensions of existing known
mineralised systems and potential common targets.
Trundle drilling
Kincora's new phase of drilling at the Trundle project commenced
in January 1, and is testing 5 adjacent systems and
separate large-scale porphyry targets across an existing 3.2km
mineralised strike – see Figure 1.
Assay results have been returned for Kincora's first holes at
the Dunn's North and Dunn's South prospects, located 640m metres apart. These assays have confirmed
significant zones of potentially ore grade porphyry mineralisation
at shallow depths – see Tables 1 and 2. Petrology and fertility
analysis is pending with a review commenced of these prospects, and
adjacent open prospects, for follow up exploration.
While assay results are pending for the first hole drilled at
the Botfield prospect, notable zones of visible mineralisation have
been prioritized. These include a zone of coarse
chalcopyrite-bornite-pyrite epithermal veins, as well as massive
and banded magnetite pyrite-chalcopyrite skarn horizons.
A step out hole from previous shallow intrusive mineralisation
at the North-East Gold Zone is in progress, with a priority follow
up hole at the Botfield prospect then planned.
Botfield prospect
Kincora's first hole at the Botfield prospect, TRDD037, sought
to test for the first time a large magnetic high complex coincident
with shallow anomalous copper-gold and an IP chargeability high
anomaly.
The concept Kincora sought to test was of a large untested skarn
and/or porphyry complex, potentially associated with the emerging
Southern Extension Zone (SEZ) discovery. This discovery was made by
Kincora in the past 18 months to the west, and the southern
extension of the multiple phase intrusive complexes intersected by
Kincora and previous explorer drilling.
While assay results are pending, notable zones of visible
mineralisation have been prioritized and include:
- Coarse banded chalcopyrite-bornite-pyrite epithermal veins
(from 128-132m)
- Massive magnetite-pyrite-chalcopyrite skarn (>80% magnetite,
from 376-407m)
- Banded magnetite-pyroxene-feldspar skarn with pyrite and
chalcopyrite (<30% magnetite from 407-425m)
Hole TRDD037 supports the current working interpretation that
the Botfield prospect is located in an uplifted block, in the order
of almost 500m, to the immediately
adjacent SEZ prospect across an interpreted significant N-S fault
zone – see Figures 1 and 2.
The relatively shallow chalcopyrite-bornite-pyrite epithermal
veins are new to the project, and support vectors to a more
proximal and prospective level in porphyry system - see Photo 1
(a).
Hole TRDD037 intersected over 30 metres of massive magnetite
skarn from only 330 metres vertical depth (see Photo 1 (b))
compared to an interpreted equivalent horizon of 34 metres from 710
metres vertical depth in TRDD032, located 430 metres to the west,
with similar stratigraphic horizons above and below these
zones.
The geophysical inversions and targets for TRDD037 correlate
well with visual logging and current interpretations of the
returned diamond core, benefiting from the relatively shallow
depths and width of the massive magnetic zone and associated
sulphides.
The Botfield prospect has been prioritised for follow up.
Planned hole TRDD039 will step out a further 250 metres to the east
testing the up-dip coincident magnetic and induced polarisation
(IP) chargeability anomaly cores, and at potentially open-pitable
depths.
Assay results from completed hole TRDD037, and planned TRDD039,
will assist in determining the next phases of drilling at the
Botfield and SEZ prospects.
As announced in December 20222, Kincora has been
awarded a drilling grant from the latest New Frontiers Exploration
program by the New South Wales State Government to follow up the
intersected 34m @ 1.45 g/t gold and
0.25% copper in skarn, including an interpreted porphyry vein that
drove 2m at 19.9 g/t gold and 2.43%
copper (hole TRDD032) within the SEZ 3.

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

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

Kincora Copper Limited – NSW
drilling program
Following extensive technical reviews, the Company's ongoing
drilling program in NSW will seek to drill test 13 new copper-gold
discovery opportunities across 5 projects.
In January 2023, drilling
commenced at the flagship and brownfield Trundle project seeking to
test 5 adjacent system and separate large-scale porphyry targets
across an existing 3.2km mineralised strike and magnetic complex at
the southern portion of the Trundle license.
Trundle project
background
The Trundle project is located in the Junee-Narromine volcanic
belt of the Macquarie Arc, less than 30km from the mill at the
Northparkes mines in a brownfield setting within the westerly rift
separated part of the Northparkes Igneous Complex ("NIC"). The NIC
hosts a mineral endowment of approximately 24Moz AuEq (at 0.6% Cu
and 0.2g/t Au) and is Australia's
second largest porphyry mine comprising of 22 intrusive porphyry
discoveries, 9 of which with positive economics.
The Trundle project includes one single license covering
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, unless above detection
limit where the interval is re-assayed using fire assay method with
atomic-absorption finish (Au-AA26 method of ALS). The technique
allows accurately determine the gold grade above 0.01 g/t and
suitable for high – grade samples where grade exceeds 10 g/t.
- Multiple elements: ME-ICP61 (4 acid digestion with ICP-AES
analysis for 33 elements) and ME-MS61 (4 acid digestion with
ICP-AES & ICP-MS analysis for 48 elements), the latter report
for TRDD001 and former reported for holes TRDD002-TRDD022.
- Copper oxides and selected intervals with native copper:
ME-ICP44 (Aqua regia digestion with ICP-AES analysis) has been
assayed, but not reported.
- Assay results >10g/t gold and/or 1% copper are
re-assayed.

Sampling
techniques
|
- Nature and quality
of sampling (e.g.
cut channels, random chips, or
specific specialised industry standard
measurement tools appropriate to the
minerals under investigation, such as
down hole gamma sondes, or
handheld XRF instruments, etc.).
These examples should not be taken as
limiting the broad meaning of sampling.
- Include reference
to measures taken
to ensure sample representivity and
the appropriate calibration of any
measurement tools or systems used.
- Aspects of the
determination of
mineralisation that are Material to
the Public Report.
- In cases where
'industry standard'
work has been done this would be
relatively simple (e.g. 'reverse
circulation drilling was used to obtain
1 m samples from which 3 kg was
pulverised to produce a 30 g charge
for fire assay'). In other cases more
explanation may be required, such as
where there is coarse gold that has
inherent sampling problems. Unusual
commodities or mineralisation types
(eg submarine nodules) may warrant
disclosure of detailed information
|
- Kincora Copper
Limited is the operator of the
Trundle Project, with drilling using diamond coring
and Air coring methods by DrillIt Consulting Pty
Ltd, from which sub-samples were taken over 2 m
intervals and pulverised to produce suitable
aliquots for fire assay and ICP-MS.
- Diamond drilling
was used to obtain orientated
samples from the ground, which was then
structurally, geotechnically and geologically logged.
- Sample interval
selection was based on geological
controls and mineralization.
- Sampling was
completed to industry standards with
1⁄4 core for PQ and HQ diameter diamond core and
1⁄2 core for NQ diameter diamond core sent to
the lab for each sample interval.
- Samples were
assayed via the following methods:
- Gold: Au-AA24 (Fire
assay) unless above
detection limit where the interval is re-assayed
using fire assay method with atomic-absorption
finish (Au-AA26 method of ALS). The technique
allows to accurately determine the gold grade above
0.01 g/t and suitable for high – grade samples
where grade exceeds 10 g/t.
- Multiple elements:
ME-ICP61 (4 acid digestion
with ICP-AES analysis for 33 elements) and
ME-MS61 (4 acid digestion with ICP-AES &
ICP-MS analysis for 48 elements)
- Copper oxides and
selected intervals with native
copper: ME-ICP44 (Aqua regia digestion with
ICP-AES analysis) has been assayed, but not reported
- Assay results
>10g/t gold and/or 1% copper are
re-assayed
- Historic sampling
on other projects included soils,
rock chips and drilling (aircore, RAB, RC and
diamond core).
|
Drilling
techniques
|
- Drill type (e.g.
core, reverse
circulation, open-hole hammer,
rotary air blast, auger, Bangka,
sonic, etc) and details (e.g. core
diameter, triple or standard tube,
depth of diamond tails, face-sampling
bit or other type, whether core is
oriented and if so, by what method,
etc.).
|
- Drilling by Kincora
at Trundle used diamond core
drilling with PQ, HQ and NQ diameter core
depending on drilling depth and some shallow
depth Air core drilling.
- All Kincora core
was oriented using a Reflex ACE
electronic tool.
- Historic drilling
on Kincora projects used a variety
of methods including aircore, rotary air blast,
reverse circulation, and diamond core. Methods
are clearly stated in the body of the previous reports
with any historic exploration results.
|
Drill sample
recovery
|
- Method of recording
and assessing
core and chip sample recoveries
and results assessed.
- Measures taken to
maximise sample
recovery and ensure representative
nature of the samples.
- Whether a
relationship exists between
sample recovery and grade and
whether sample bias may have
occurred due to preferential loss/gain
of fine/coarse material.
|
- Drill Core recovery
was logged.
- Diamond drill core
recoveries are contained in
the body of the announcement.
- Core recoveries
were recorded by measuring the
total length of recovered core expressed as a
proportion of the drilled run length.
- Core recoveries for
most of Kincora's drilling were
in average over 97.1%, with two holes averaging
85.0%
- Poor recovery zones
are generally associated with
later fault zones and the upper oxidised parts of
drill holes.
- There is no
relationship between core recoveries
and grades.
|
Logging
|
- Whether core and
chip samples have
been geologically and geotechnically
logged to a level of detail to support
appropriate Mineral Resource
estimation, mining studies and
metallurgical studies.
- Whether logging is
qualitative or
quantitative in nature. Core (or
costean, channel, etc.) photography.
- The total length
and percentage of the
relevant intersections logged.
|
- All Kincora holes
are geologically logged for their
entire length including lithology, alteration,
mineralisation (sulphides and oxides), veining and
structure.
- Logging is mostly
qualitative in nature, with some
visual estimation of mineral proportions that is
semi-quantitative. Measurements are taken on
structures where core is orientated.
- All core and Air
core chips are photographed.
- Historic drilling
was logged with logging mostly
recorded on paper in reports lodged with the NSW
Department of Mines.
|
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.
- Follow up high
grade gold assay results received for
a 2 meter interval in TRDD032, with re-assays for
three samples where undertaken from reject
samples (the coarse part of samples) seeking to
confirm the original high grade interval (12.6g/t
gold) and also to test if quarter core samples
were representative. Duplicated values for the two
adjacent samples were in-line with both gold
(via Au-AA26 and Au-AA26D, duplicate,
techniques) and base metals higher than the original
results for the high-grade sample.
- No other duplicate
samples were taken.

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: https://www.kincoracopper.com/investors/asx-prospectus

Geology
|
- Deposit type,
geological setting and
style of mineralisation.
|
- All projects
ex EL7748 (Condobolin) and
EL9340
(Condobolin East) 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 and is noted in the summary
tables of significant mineralised intervals of the respective
holes.
- 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
and figures are included in the body
of the report, including the current working models and
interpretations.
|
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 non-mineralised 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.
|
- Recent drilling has
concluded at the Mordialloc, Mordialloc and
Trundle Park targets at the time of publication of this report
and plans for further step-out drilling are in place at the
Trundle Park, Mordialloc and Botfield prospects.
- Reviews are ongoing
and concluding for the newly identified
North-East Gold Zone and recent Southern Extension (skarn)
Zone discovery at the Trundle Park prospect. Further
drilling and second phase programs are proposed at
other Trundle project areas, including air core programs at the
Mordialloc, Dunn's North 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. Permitting,
planning and drill rig/team scheduling is ongoing, and is
subject
to improved ground conditions.
