- Assay results for TRDD030 return cumulative gold and copper
mineralisation across 164m in three
skarn zones:
-
- Localised higher grade intervals of up to 1.68g/t gold and
3.61% copper
- Middle Skarn: 29m @ 0.54
g/t gold and 0.22% copper, including 5m @ 1.46g/t gold and 0.56% copper
- Lower Skarn: 22m @ 0.51
g/t gold
- Most recent hole TRDD032 has intersected cumulative
skarn intervals of >170m below
multiple zones and phases of moderate to strong potassic and
later epidote alteration, in places cut by quartz veinlets with
chalcopyrite, bornite and covellite mineralisation in
volcanics.
- Tabular, bedded, mineralised skarn system across three
zones confirmed over >325m
NW-SE strike and >225m W-E
wide (and open) in the Southern Extension Zone (SEZ)
discovery.
- Skarn alteration, widths and mineral zonation coupled with
sulphide veining in overlying volcanics supports working
interpretation of targeted causative intrusive source on a
lateral setting.
- Hole TRDD033 commenced stepping out a further
225m east and testing the
southern extension for mineralised intrusions.
- Internal and external specialist geological reviews of
the Southern Extension Zone commenced, seeking to maximize
vectors for follow up drilling.
- Assay results are pending for 8 prospects across the Trundle
and Fairholme projects, including for 2 diamond holes (from the
SEZ discovery) and 72 air-core holes. Within the Mongolian
license portfolio, completion of resource estimate work for the
Bronze Fox project is expected shortly.
MELBOURNE, Australia,
April 26, 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, noted:
"Assay results from TRDD030 with intervals of
ore grade copper and gold in skarn further illustrate a very large
and multiple phase skarn mineralised system at the Southern
Extension Zone (SEZ) discovery.
And now the most recent hole (TRDD032) has
extended the system more than 150m to
the southeast by also intersecting significant widths with visible
chalcopyrite associated with magnetite-garnet-sulphide skarn and
later retrograde quartz-carbonate-sulphide veins. This hole also
has strong alteration and high temperature sulphides, including
bornite, covellite and chalcopyrite, in the volcanics overlying the
skarn.
With four completed holes, two with assay
results, along a 330 metre strike which is 225m wide (and open in all directions), we are
increasing our geological firepower to maximise our knowledge of
this highly prospective SEZ discovery. We are continually seeking
to refine vectors for high priority follow-up drilling of our
primary target, a large-scale copper-gold mineralised porphyry
intrusion source for the skarn mineralisation. This work will now
be reinforced by the knowledge of Dr. Alan
Wilson, a leading independent economic geologist consultant
with considerable global and Macquarie Arc porphyry experience,
whom I have previously worked very closely with.
Recently commenced follow up hole TRDD033 is
another large step out to the east, seeking to extend the SEZ and
locate the porphyry intrusion source. This hole is expected to
significantly contribute to our review work and have implications
for both follow up drilling at the SEZ and also the Botfield skarn
prospect which lies further south."
An accompanying presentation, including further details on the
Trundle project, Kincora's pending news flow pipeline and
exploration plans is available at www.kincoracopper.com

TRDD032 at the Trundle Park prospect
Figure 3: Concepts and target for commenced hole TRDD033
Hole TRDD033 will provide significant new information for the
ongoing review of the SEZ and also the neighbouring southern
Botfield skarn mine prospect. TRDD033 is a ~225m step out east of
the mineralised magnetite skarns intersected in TRDD032 and testing
the southern strike potential of intrusions intersected to the
north.
Assay results for drill hole
TRDD030 and visuals of TRDD032
Assay results from TRDD030 further illustrate a very large and
multiple-phase mineralising system, with cumulative mineralised
intervals of 164m covering three
separate skarn horizons. Zones of prospective gold and copper
tenure were returned in both the Upper, Middle and Lower Skarns.
Assay results are included in Tables 1 and 2.
These results follow not dissimilar widths and grades in
previously reported TRDD0291, which was the first hole
into the Southern Extension Zone (SEZ) discovery area. While not
thought to be economic intervals, they are interpreted to be
suggestive of a significant scale source, provide vectors for
following up drilling and strongly support Kincora's primary target
of a causative porphyry intrusion.
Most recently completed hole TRDD032 has intersected cumulative
skarn alteration across >170m
down-hole and expanded the skarn system significantly to the east,
and south.
The four completed holes to date into the SEZ (TRDD029-32) have
confirmed a tabular, bedded, mineralised skarn system across three
zones over at least a 325m SSE strike
and 225m W-E wide system (and open) –
see Figures 1-3. This is very encouraging and significant in the
context of the Macquarie Arc.
Similar to previous holes in the SEZ, hole TRDD032 has returned
visual copper sulphides associated with intervals containing
magnetite, in particular the assemblages with (a) early
magnetite-garnet-pyrite-chalcopyrite, in turn cut by later
quartz-carbonate-hematite-pyrite-chalcopyrite veins and open space
fillings.
However, there are also traces of bornite, covellite and
chalcopyrite occurring in the upper volcanoclastic rock sequences
in TRDD032 associated with an early potassic (Kspar) alteration
interpreted to be overprinted by an epidote-quartz-sulphide
alteration phase. Examples of key mineralised zones/vectors from
hole TRDD032 are included in Figure 5.
Review of vectors for follow up
drilling
The width, alteration and mineralisation of the respective three
skarn zones, coupled with alteration and mineralisation in the
overlying volcanics from holes TRDD029-32 are providing insights to
the interpreted fluid pathways from the targeted causative porphyry
intrusion and source.
With assay results available for TRDD029 and TRDD030, and
detailed initial logging of TRDD031 and TRDD032, an internal review
has commenced seeking to maximise the geological information
available and refine vectors for high priority follow-up
drilling.
Visits by Specialist
Consultants
Kincora's hosting at site of both Professor Dave Cooke and Dr. Lejun
Zhang, from the Centre for Ore Deposit and Earth Sciences
(CODES), University of Tasmania
(UTAS), has already assisted this review. The review will be also
supplemented by a more detailed input from, and core relogging by,
Dr. Alan Wilson (GeoAqua
Consultants). Dr. Wilson is a leading independent economic
geologist consultant with considerable global and Macquarie Arc
porphyry experience (refer to Figure 4 for Kincora's adaptation of
Dr. Wilson's original Macquarie Arc model for our current
interpretation of the location of the Southern Extension Zone
relative to the targeted causative intrusive source, and a lateral
setting to the existing intersected skarn system).
Figure 4: The Southern Extension Zone is interpreted to be on
a lateral setting to the primary target causative intrusive source
and porphyry target
Conceptual and illustrative setting of the SEZ relative to the
Macquarie Arc porphyry model with a targeted causative intrusive
porphyry source being at a lateral setting to the skarns
intersected in TRDD029-32 (similar to the Big Cadia skarn and
Cadia Quarry). The Macquarie Arc
porphyry model is adopted from Dr. Alan
Wilson.
Exploration outlook
Recently commenced follow up hole TRDD033 is another large step
out to the east, seeking to also determine if the intrusions
intersected to the north continue into this portion of the SEZ.
TRDD033 is a ~225m step out east from the mineralised
magnetite skarns intersected in TRDD032 and ~430m from TRDD031.
TRDDo33 is also ~450m south of previously intersected mineralised
intrusions (TRDD010). This hole is expected to significantly
contribute to the review and have implications for both follow up
drilling at this immediate discovery zone and also the neighbouring
southern Botfield skarn prospect.
Following completion of the current hole TRDD033, as the ongoing
technical review is concluded and before an existing access window
closes, a second diamond drill hole is scheduled at the Mordialloc
North-East prospect and prior to a proposed shallow 26-hole
air-core program at the Mordialloc prospect.
The Company currently has a significant amount of assay results
pending for 8 prospects across 2 projects (Trundle and
Fairholme).
At Trundle this includes two diamond holes at the SEZ (TRDD031-32)
and 50 shallow air-core holes from the Dunn's and Ravenswood South prospects.
For the Fairholme project this includes 22 air-core holes across
the Anomaly 2, Gateway prospects, Kennel, Glencoe and Driftway-C prospects (with
drilling at the Gateway prospect included under a New Frontiers
Cooperative Drilling program grant – see the January 31st, 2022 press release
"Kincora awarded $389,500 in
drilling grants" for further details).
Within the Mongolian license portfolio, a maiden JORC resource
shortly expected for the Bronze Fox project.
Further details of the Company's news flow pipeline and
exploration strategy is outlined on slide 5 of the accompanying
updated corporate presentation (available at www.kincoracopper.com
).

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.

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

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

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.
