Novo Resources Corp. (
Novo or the
Company) (ASX: NVO) (TSX: NVO) (OTCQX: NSRPF) is
pleased to provide an exploration update on programs at the Egina
Gold Camp and Balla Balla Gold Project, including results from RC
drilling at Nunyerry North (Figure 1) and the recent Determination
Wide Aboriginal Heritage Protection Agreement with the Kariyarra
Aboriginal Corporation which will allow for on ground exploration
to commence at Balla Balla and ongoing work by De Grey on the
Becher Project at the Egina farm-in and Joint Venture.
Novo has been exploring the Mallina Basin and
adjacent areas in the Pilbara since 2017, focusing on gold
prospectivity but also with a view to adding value through lithium,
base metals and other commodities.
This work culminated in 2023 with considerable
success delivered from drilling at Nunyerry North and through the
completion of transformative deals with De Grey Mining (De
Grey) (the Egina farm-in and Joint Venture (Egina
JV)) and Sociedad Quimica y Minera de Chile S.A.
(SQM) (the Harding Battery Metals Joint Venture
(HBMJV)). These strong JV partnerships give Novo
exposure to a new discovery through JV partner expenditure and
allows Novo to focus on progressing exploration across targeted
prospects in the Pilbara and Victoria and advance assessment of
project generation opportunities.

EGINA GOLD CAMP
The Egina Gold Camp is a contiguous tenement
package, covering a series of structurally complex, gold-fertile
corridors, transecting the Mallina Basin in the north and mafic /
ultramafic sequences further south.
These corridors are part of the regional
structural architecture that encompasses De Grey’s 12.7 Moz
Hemi Gold Project (Hemi)3 to the
northeast. This tenure has been one of the main focus areas of
Novo’s exploration programs over the last eighteen months,
culminating in the Egina JV, and delineation of the
Nunyerry North orogenic gold prospect in 2023.
Nunyerry North
First pass drilling at Nunyerry North in late
20234 was restricted to a central zone of
structurally controlled outcropping quartz veins with high-grade
gold rock chip results (Figure 2).
Figure 2: Nunyerry North geological
interpretation, showing 2023 and 2024 drilling completed
Drilling generated significant intercepts in
Main Lode #1 in a shallow plunging shoot within a brittle basalt
unit, between two significant shear zones. Other mineralised lodes
were identified below the Main Lode #1, but are structurally blind,
and do not outcrop at surface.
Best results from the 2023 RC program
include:
-
6 m at 6.12 g/t Au from 37 m, including 5 m at
7.28 g/t Au from 37 m (NC017)
-
11 m at 2.52 g/t Au from 22 m, including 6 m at
4.19 g/t Au from 22 m (NC014)
-
13 m at 1.89 g/t Au from surface, including 4 m at
2.56 g/t Au from 3 m (NC004)
-
4 m at 5.71 g/t Au from 40 m, including 3 m at
7.47 g/t Au from 41 m (NC015)
-
17 m at 1.34 g/t Au from 37 m, including 4 m at
3.77 g/t Au from 50 m; 18 m at0.60 g/t Au from 75 m and 7 m at 1.78
g/t Au from 59 m (NC022) – highlighting significant mineralisation
over a 55 m intercept.
Novo recently completed a follow-up RC drill
program of 34 holes for 3,942 m aimed at extending known
mineralisation in the Main Area and at testing other more regional
targets defined by soil sampling, mapping and rock chip sampling
(Figure 2). These regional targets included the Estrid Fault, west
of the Aurora Fault (‘Aurora West’) and a porphyry unit south of
the Skadi Shear (‘Porphyry’).
Angled drill holes ranged from 66 m to 192 m in
depth (average 116 m) and were drilled on 40 m to 80 m spaced
sections. All holes were drilled oriented perpendicular to the
interpreted mineralised trend, with the intersected widths
representative of the true width of the mineralisation unless noted
otherwise.
Main Area - Drilling was
designed to extend mineralisation along strike to the east of, and
down plunge of the Main Lode #1 and to understand the context of
previous high-grade intercepts in the east of the area drilled in
2023. Best results (Figure 3) from the latest drilling include:
-
9 m at 2.52 g/t Au from 87 m, including 2 m at
8.89 g/t Au from 92 m (NC061)
-
2 m at 7.38 g/t Au from 42 m (NC051)
-
11 m at 1.26 g/t Au from 85 m, including 4 m at
2.31 g/t Au from 85 m (NC053)
See Appendix 1 for hole details and Appendix 2
for complete assay results.
Drilling has extended known mineralisation by
250 m to approximately 500 m in strike (Figure 3). NC061
intersected the Main Lode # 1 approximately 100m down plunge of
2023 drilling extending the plunge extent to over 300m. An
additional mineralised shoot is also interpreted towards the east,
possibly related to a splay fault recognised from chips and surface
mapping. Mineralisation is still open to the east and at depth.
Anomalous and significant results from the
current program are currently being re-analysed by multi-pot
PhotonAssay™. The larger sample methodology may better resolve any
coarse gold component. These assays are pending.

NNW) showing m x g/t Au (downhole width)
Estrid Fault
Three holes were drilled into the Estrid Fault
target where high-order soil anomalies and surface alteration and
veining defined the mineralised corridor. All three holes generated
significant gold intercepts, including:
-
13 m at 2.68 g/t Au from 66 m, including 3 m at
10.41 g/t Au from 66 m (NC046)
-
11 m at 2.20 g/t Au from 84 m, including 1 m at
18.06 g/t Au from 86 m (NC046)
-
2 m at 6.30 g/t Au from 15 m (NC062)
-
17 m at 1.85 g/t Au from 25 m, including 7 m at
3.55 g/t Au from 25 m (NC063)
See Appendix 1 for hole details and Appendix 2
for complete assay results.
Hole NC046 intersected strong silica-sericite
alteration (Figure 4).
Figure 4: NC046 drill chips showing altered
basalt, labelling assay result (Au, top) and mineral / alteration
intensity / vein percent (bottom).
None of the drilling was at optimal angles due
to the terrain and these holes may have drilled at low angles to
mineralisation along the fault, although true orientation of
mineralisation cannot be determined at this stage. Mineralisation
is open along strike for several hundred metres.
Porphyry Target - Three holes
were drilled into the Porphyry target where Novo rock chip samples
have returned several positive results from brecciated quartz
veins5. The porphyry is up to 1 km long by 85 m wide in outcrop and
disseminated pyrite is common throughout, with areas showing up to
5% disseminated to blebby pyrite.
Drilling intersected a porphyritic rhyolite to
rhyodacite with pyrite (+/- chalcopyrite) mineralisation, with a
best result of 7 m at 0.1 g/t Au, coinciding with
elevated pXRF assays on RC powder of up to 0.21% Cu.
Results to date do not warrant immediate follow
up in the direct target area. However anomalous Au and Cu results
are encouraging for exploration prospectivity in the district, as
porphyry style mineralisation was not previously recognised in this
area.
Aurora West – A broad soil
anomaly was tested at Aurora West, in stratigraphy interpreted to
be the offset basalt host to mineralization at the Main Lode #1.
Whilst quartz veins and minor sulphide were intersected in a number
of holes, no significant intercepts were recorded.
Egina JV Update
De Grey is currently progressing the first stage
of its earn-in at the Egina JV, with a minimum spend of A$7 million
to be completed in 18 months (December 2024). De Grey needs to
invest up to A$25 million on exploration at Becher and adjacent
tenements within 4 years to earn a 50% direct interest in the
JV.
Follow-up aircore (AC) and RC
drilling programs commenced at Novo’s flagship Becher Project by De
Grey in late May 2024, with two rigs concurrently conducting a
proposed approximate 28,000 m combined drill program. The RC drill
program is focussed initially at Heckmair and has been designed to
follow up on encouraging results at Lowe, Heckmair, and
Whillans.
The AC drill program has commenced at Lowe and
aims to provide better geochemical coverage over structural and
intrusion targets. At 30 June 2024, a total of 38 RC holes for
4,975 m and 201 AC holes for 16,955 m had been completed. Results
are expected in late Q3 2024.
Tabba Tabba Shear Corridor
The Tabba Tabba Shear Corridor is a deep NE
trending mantle tapping structure/series of structures in the
Southern Egina Gold Camp (Figure 1) and host to numerous gold
occurrences.
The 60 km strike of the Tabba Tabba Shear
Corridor on Novo tenure (Figure 5) is underexplored, as access is
difficult and significant parts of the corridor are covered with
shallow alluvium, colluvium and sand, and part of the corridor is
overlain by Fortescue Group Basalt.
Novo have recently completed a re-interpretation
of the corridor utilising new advances in understanding from
geology, geochemistry, and remote sensing/geophysics, and based on
results from Nunyerry North, previous reconnaissance style
exploration during 2019 to 2023 and the understanding of Hemi.
Several conceptual targets have been identified, with most having
received little to no historical exploration.
Figure 5: Tabba Tabba Shear Corridor
Conceptual targets focus on structural
intersections of faults and shears within the Tabba Tabba Shear
Corridor, particularly where folded stratigraphy and / or minor
intrusions are noted.
The Kilkenny prospect was
explored by Kilkenny Gold NL (Kilkenny) in the late 1990s and
comprised several short costeans and 18 shallow percussion holes
for a total of 530 m drilled, following up a coherent gold in soil
anomaly. Despite the very small program, Kilkenny returned best
costean samples of 8 m at 4.2 g/t Au, 8 m at 2.1 g/t Au, and
drilling results of 5 m at 5.0 g/t Au from 9 m (ACN05) and 5m at
1.7 g/t Au from 14 m, including 2 m at 3.5 from 14 m (ACN13)6.
See Appendix 3 for hole details and Appendix 4
for complete assay results.
At Teichman Top, several
historic workings are present, and modern exploration includes
results of 25.5 g/t Au and 32.3 g/t Au from rock samples7. This
prospect is located within the Yandeyarra Reserve and has not been
accessible in recent years due to the requirement to complete
access agreements.
Drilling and surface sample results may not be
representative of mineralisation in the district.
Novo has recently commenced mapping and surface
sampling over prospective parts of the Tabba Tabba Shear Corridor
to delineate targets for potential future drill testing. The
initial program comprises six mapping areas and approximately 1,200
surface soil samples, with opportunistic rock and stream sediment
samples where appropriate.
BALLA BALLA GOLD PROJECT
The Balla Balla Gold Project (Figure 6) includes
Novo granted tenements and tenement applications immediately north
of the Egina Gold Camp (Figure 1) and overlaps with the Kariyarra
and Ngarluma / Yindjibarndi Native Title Determination areas.
Novo reports that a Determination Wide
Aboriginal Heritage Protection Agreement (the
Agreement) has been signed between Novo and the
Kariyarra Aboriginal Corporation. The execution of this Agreement
streamlines the interactions between Novo and the Kariyarra People
and confirms Novo’s commitment to open, honest and transparent
dealings with the Traditional Owners of the Pilbara Region. The
Agreement also provides for compensation payments for the benefit
of the Traditional Owners which are customary and in line with
normal commercial terms for similar agreements of this nature.
The Agreement enables the grant of tenement
application E47/4703 at Balla Balla, which is prospective for gold,
base metals, and lithium mineralisation. A cultural site avoidance
heritage survey has already been completed with Kariyarra, jointly
organised by Novo and SQM with a final report expected within the
next few weeks. This survey will enable AC drilling to commence
after the grant of the tenement.
The Balla Balla Gold Project
covers a significant flexure of the Sholl Shear
Zone, a major crustal suture between the Central Pilbara
Tectonic Zone and the Karratha Terrane. The Sholl Shear Zone is a
NE – SW striking mylonite zone, trending parallel to the
Mallina Shear and Tabba Tabba Shear Corridor, with a
series of linking structures, including the Loudens Fault and
Wohler Shear. Novo holds approximately 60 km of strike length over
the Sholl Shear Zone at Balla Balla, including several splay
structures.
Figure 6: Balla Balla Project geology showing
Sholl Shear Zone corridor and complex folded stratigraphy
The Sholl Shear Zone and
surrounds are prospective for orogenic and intrusion related gold,
base metal mineralisation and lithium, and Novo intends to rapidly
progress exploration by regional AC traverses over key targets.
Novo retains upside to this lithium potential
with the HBMJV, where SQM have paid A$10M for a 75% interest in
five of Novo’s tenements. Under the HBMJV, SQM will be the manager
and Novo is free carried until a decision to mine. Novo also
retains the gold, silver, PGE, and copper / lead / zinc mineral
rights8.
Balla Balla AC Drilling
Several conceptual targets on Novo’s tenure have
been identified through comprehensive analysis and interpretation
of geophysical and remote sensing data, existing geochemical
datasets and searches through historic reporting over the broader
area. Many of these targets have received little to no historical
exploration presenting new opportunities for discovery and
development.
Tenement application E47/4703 shows significant
geological complexity in magnetic data in proximity to the deep
mantle tapping Sholl Shear Zone. South of this shear, the
stratigraphy comprises interbedded varying sedimentary units of the
Mallina Formation and to the north is a fault-bound wedge of
Mallina Formation adjacent to felsic volcaniclastics and porphyry
dacites & rhyolites of the Red Hill Volcanics. These are also
intruded by the young mafic-ultramafic rocks of the Sherlock
Intrusion and crosscut by late dolerite dykes (Figure 6).
The complex geological setting and evidence of
folded stratigraphy in a potential extension of the Loudens Fault
provides a compelling region for a first pass AC drilling program
primarily targeting gold and copper mineralisation. Novo has
designed a preliminary 8,000 m AC program pending tenement grant
and finalisation of the heritage survey. Drilling is expected to
commence in Q4 2024.
The program comprises regional drill lines to
test approximately 10 km of target strike extent. Lines are
designed at a nominal spacing of 320 m or 640 m, preferentially
targeting interpreted structures and fold closures. This program
will utilise the same refined and optimised in-field sampling
methodology and dispatch as that used at the Becher Project during
2023 AC drilling. The technique led to rapid sample collection,
dispatch and laboratory turnaround times.
This program is aimed at determining bedrock
geochemistry to generate a coherent litho-geochemistry dataset
driving geological understanding and enabling identification of
mineralogical systems and their primary controls.
ANALYTIC METHODOLOGY
Nunyerry North RC chips were split directly off
the cyclone on the drill rig at one metre intervals and sent to
Intertek Genalysis (Intertek) in Perth, Western
Australia with the entire sample smart crushed to -3 mm (NVO02 prep
code), with a 500 g split sample analysed for gold using
PhotonAssay™ (PHXR/AU01). Remaining drill spoil was retained
on site in numbered green bags.
QA/QC for RC samples are inserted at the rate of
2 x 600 g standards per 100, 2 x 600 g blanks per 100 and 4
duplicates per 100, providing a total of 8% QA/QC. Field duplicates
are collected from the cone splitter at the time of drilling.
Intertek also inserts PhotonAssay™ blanks and certified
standards at the rate of 4 per hundred.
All significant sample intervals greater than
0.3 g/t Au or part of an interval that falls within an interpreted
mineralisation shape were resubmitted for multiple PhotonAssay™
analysis. This comprised a total of 265 samples, selected from
remaining crushed material available in the laboratory, averaging
four pots per analysis. Samples were analysed ‘in full’ by
splitting the crushed material into multiple PhotonAssay™ jars
(PHXR/AU01) with a maximum of five jars.
Kilkenny constructed trenches through soil and
rubble to ensure sampling could target rock in situ. Samples were
collected by hand over two metre intervals along the trench and
perpendicular to stratigraphy, with most costeans approximately 20
metres long. Samples were submitted to Genalysis Laboratories and
analysed for gold via Fire Assay (AAS, 0.01 g/t detection
limit).
Drilling by Kilkenny was completed with a
600cfm/250psi AC hammer rig, with each meter captured in green bags
which have since been rehabilitated. From the green bags, four
metre composite samples were speared and submitted to Genalysis
Laboratories and analysed for gold via Fire Assay (AAS, 0.01 g/t
detection limit). Composites greater than 1 metre were speared on
site and resubmitted for re assay.
Kilkenny does not report duplicate samples or
insertion of CRMs or blanks, and historical results are not
considered representative of mineralisation in the district.

JORC Code, 2012 Edition – Table 1
Section 1: Sampling Techniques and Data
(Criteria listed in the preceding section also apply to this
section)
Criteria |
JORC Code explanation |
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 (e.g., submarine nodules) may warrant
disclosure of detailed information.
|
- The Nunyerry North Prospect located in the Egina Gold Camp was
tested using reverse circulation (“RC”) drilling.
- Drill holes were located to intersect the main interpreted vein
sets and obliquely intersect shears and faults.
- RC drilling obtained one metre split samples from a face
sampling hammer bit using an industry standard cone splitter
attached to the cyclone to collect an approximately 2-3 kg split
material in pre-numbered calico bags.
- Regular air and manual cleaning of the cyclone was conducted at
the end of every hole, to remove buildup of dust and chip material
where present.
- Standards, blanks and replicate assays were inserted into the
sample sequence in the field.
- A downhole Reflex single shot and downhole gyro survey tool
were calibrated prior to the drilling program commencing, and a
pXRF machine for multi-element analysis was calibrated every
day.
- The 2-3 kg sample was dried and crushed to <2mm at the lab
to obtain a 500g sample for Au analysis by Chrysos PhotonAssay™ at
an independent certified laboratory.
- For a subset of samples, the remaining crushed material was
pulverized to 75 µm at 85% passing and tested using 50 gram Fire
Assay and/or 1 kg Screen Fire Assay.
- Remaining crushed material or material riffle split from green
bags were submitted to be crushed, and analysed using multiple
PhotonAssay™ for a larger sample better representing coarse gold
systems.
- Based on statistical analysis of these results, there is no
evidence to suggest the samples are not representative.
- Costean samples by Kilkenny were collected by grab sampling 1 –
3 kg of material along 2 m intervals. Drill samples were speared
from one metre sample piles into 4 m composites, submitted to
Genalysis Laboratories, Western Australia for analysis via Fire
Assay.
|
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).
|
- A total of 35 RC holes and 1 open hole percussion for an
aggregate total of 3,942 m were completed with depths ranging from
66 m to 192 m, averaging 116 m. RC drilling was undertaken using a
5 ¼ inch face sampling hammer bit.
- Kilkenny drilled 18 shallow percussion holes for 530 m in 1998
using a 600cfm/250psi aircore rig and hammer bit. Depths range from
20 m to 40 m and average 28 m.
|
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.
|
- The samples were visually checked for recovery as an estimate
of variance from the average 100% recovery and were checked for
moisture content and sample quality (contamination), recorded every
metre by the geologist.
- The cyclone was routinely cleaned ensuring no material build
up.
- The ground conditions were excellent with consistent recoveries
and generally dry samples.
- The cyclone emits minimal dust such that sample bias by losing
fines and concentrating coarse material is deemed to be
negligible.
- The possibility of sample bias through selective recoveries is
considered negligible and there is no relationship between grade
and sample recoveries/quality or moisture content.
- Sample recovery information for Kilkenny 1998 samples is not
recorded.
|
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.
|
- One metre RC drill samples were directly split on the drill rig
using an industry standard cone splitter to collect approximately
2-3 kg of split material in a pre-numbered calico bag and the
remainder of the sample (bulk sample) collected in a numbered large
green plastic bag and laid out in rows or 20 or 30 samples. The
bulk sample was speared diagonally to collect a representation of
the material for each metre. The speared 1 m sample was sieved to
separate the fine and coarse material. The geologist then logged
chips from each metre in direct sunlight (including lithology,
grain size, colour, alteration, weathering, vein percent and
sulphide mineralogy) before part of the sample was placed in a chip
tray for permanent storage.
- Fine material was collected in chip trays and analysed using
the pXRF for pathfinder elements.
- 3,942 m were logged representing all drilled meters from all
drill holes.
- The logging was qualitative, except for logging of vein percent
which was quantitative.
- Kilkenny recorded downhole geology for all intervals by
recording primary lithology information from spearing sample piles
at one metre intervals. Information is captured in cross
sections.
|
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.
|
- One metre RC drill samples were directly split on the drill rig
using an industry standard cone splitter to collect approximately
2-3 kg of split material in a pre-numbered calico bag.
- All samples were dry crushed to minus 2 mm by Intertek
Genalysis using a smart crusher to create a 500 g aliquot, then
assayed for gold by Chrysos PhotonAssay™ with a variable
detection limit of approximately 0.02 g/t Au.
- Coarse sample residue was retained to allow selected intervals
to be re-assayed via multi-jar PhotonAssay™.
- Kilkenny collected two metre costean composite samples and four
metre drill sample composites from individual drill piles, and were
submitted to Genalysis for Fire Assay with AAS finish, with a
detection limit of 0.01 g/t Au. Drill samples exceeding 1 gram per
tonne were re-sampled from individual sample piles for a one metre
interval analysis.
- The sampling techniques and sample size is considered
appropriate for this style of mineralisation.
|
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 (if lack of bias) and precision have
been established.
|
- Chrysos PhotonAssay™ and fire assay techniques are
considered appropriate and industry standard for Au with the
detection limits as stated.
- The assay technique is regarded as total analysis.
- The sample methodology noted above is considered appropriate
for orogenic gold style mineralization with possible coarse
gold.
- The following “blind to the lab” QAQC protocols submitted with
each batch were adhered to: 1 CRM coarse blanks and 1 CRM 200
micron blanks per 100 samples, 2 Certified Reference Material
standards per 100 appropriate for the style of assaying being
undertaken, and 4 riffle split field duplicates per 100 samples; No
QAQC issues were detected. The accuracy and precision of the data
revealed that the data is consistent with levels routinely achieved
for Au assay data and no grade bias is present
- No QAQC issues were detected.
- No QAQC protocols or performance was reported by Kilkenny, and
it is assumed that QAQC was not considered at the time.
|
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.
|
- Primary data was collected using database compatible excel
templates which were then forwarded to the database manager email
for upload to the Geobank (v2022.5) database, buffered through a
validation portal that ensures code, interval and primary record
compliance. Geobank is a front-end UX/UI tender software platform
(developed and sold by Micromine) attached to a SQL v15.1
server.
- Assay data were loaded from lab certificates received from the
registered laboratory by an internal database manager or external
database consultant, and industry-standard audit trails and
chain-of-custody was adhered to.
- Significant intercepts were calculated using a 0.3 g/t Au
cut-off and up to 3 m consecutive internal dilution. High grade
components use a 1 g/t Au cut-off and allow 1 m consecutive
internal dilution. These generated in Micromine and were verified
by at least two company geologists via manual and automatic
calculations.
- Verification included checking the data against original logs,
utilising laboratory certificates and cross-checking drill
sections.
- No adjustments of the assay data were made.
- Kilkenny 1998 sample and assay data is extracted from their
annual report, available online via WAMEX under the report ID
A57774. Assays were reported by Novo as listed, preferring one
metre splits over composites. No adjustments were made.
- Significant intercepts were calculated using a 0.3 g/t Au
cut-off and up to 3 m consecutive internal dilution. High grade
components use a 1 g/t Au cut-off and allow 1 m consecutive
internal dilution. These generated in Micromine and were verified
by at least two company geologists via manual and automatic
calculations.
|
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.
|
- All RC drill holes were drilled on
locations marked by pegs which were established using a DGPS
(Trimble RTK system) with a ± 10cm easting and northing accuracy,
and ± 20 cm vertical accuracy.
- The datum used is GDA2020 zone
50.
- Drill holes were drilled within 2 m
of the original peg with co-ordinates changed accordingly where
holes were moved slightly from the original peg position.
- Drill holes were surveyed using an
RTK (with a ± 10cm easting and northing accuracy, and ± 20 cm
vertical accuracy) at the end of the program to ascertain the exact
location of the final drill hole.
- The RTK DGPS data was used for
topographic control.
- A north seeking gyro was utilised at
every 20 m downhole to monitor hole deviation. A final survey
reading was taken every 5 m to generate an accurate hole
trace.
- Kilkenny recorded collar coordinates
using a GPS in grid AGD84, zone 50, which are converted by Novo to
GDA2020 zone 50. Costean coordinates are derived from a gridded map
in AGD84, zone 50, captured by GPS, and converted to GDA2020.
|
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.
|
- Data spacing at Nunyerry North is sufficient to demonstrate
grade and geological continuity.
- The drillholes were collared on sections approximately 40 to 80
metres apart with holes spaced at approximately 20 m spacings on
section.
- 1 m spaced drill samples were collected. Samples were not
composited.
- Kilkenny costeans and drilling are reconnaissance tests and do
not represent grade or geological continuity.
|
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 geology of the Nunyerry North target area includes sheeted
quartz vein-related gold mineralization, juxtaposed by regional
shears and offset faults in E-W trending stratigraphy dipping to
the north at 80 degrees. The shears dip to the north at 55 to 70
degrees, and the offset faults dip to the east-northeast at about
70-75 degrees. Two main quartz vein sets are identified: one
dipping 20 to 60 degrees toward the SSE and the second sub-vertical
set steeply dipping and striking N to NNE.
- Drill holes were collared to be as perpendicular as possible to
interpreted mineralisation or structure.
- Estrid Fault drilling is roughly parallel to the main structure
and may have drilled down dip of mineralisation. The true
orientation of mineralisation is currently not known.
- No sampling bias is recognized with preliminary sectional
interpretations highlighting the dip of mineralised vein sets to be
60 degrees to the SSW.
- Kilkenny drilling and costeaning is perpendicular to dominant
stratigraphy, but the host and orientation is not yet known.
|
Sample security |
- The measures taken to ensure sample security.
|
- RC samples were collected in calico bags provided to the
drillers at the start of each hole. Calico bags were tied up and
placed on the green bags before being placed in polyweave bags
which were zip tied and removed from the drill site daily.
- Samples were collected in bulka bags and transported to
Karratha by Novo staff and placed into a locked shed.
- All samples are stored and managed on site by internal
staff.
- Samples were transported by reputable transport companies to a
registered laboratory. Chain of custody is maintained by con notes
and tracking numbers from Karratha to the registered
laboratory.
- At the registered laboratory the individual samples are
registered and tracked through the preparation and analysis
process.
- Chain of custody information from Kilkenny is not
available.
|
Audits or reviews |
- The results of any audits or reviews of sampling techniques and
data.

- Type, reference name/number, location and ownership including
agreements or material issues with third parties such as joint
ventures, partnerships, overriding royalties, native title
interests, historical sites, wilderness or national park and
environmental settings.
- The security of the tenure held at the time of reporting along
with any known impediments to obtaining a license to operate in the
area.

(A77811, A81531) and Chalice Gold Mines Ltd
- 2016 - 2018 Rockford Metals Ltd (Creasy Group). Rockford Metals
were the first company to define the Nunyerry North Prospect as a
target. Upon granting, geological reconnaissance, rock chip, soil
and stream sampling was completed targeting gold associated with
the Mallina Formation, quartz veins within Archean mafic/ultramafic
greenstone belt rocks and regional locations returning maxima of
20.7 ppm Au (rock chip sample), 650 ppb Au (soil sample) and 745
ppb Au (stream sample). Surface soil geochemical sampling was
targeting a gold anomalous quartz veins hosted within Archaean
mafic/ultramafic Greenstone Belt rocks. The gold content varies
from 0.001 to 2.13 ppm (average is 0.25 ppm) and defined a 1.3 km
long, 200 m wide >30 ppb Au gold anomaly in a broadly anomalous
2 km long zone with several lower order 500 m long >10 ppb Au
anomalies.
- In 2018, an aeromagnetic/radiometric survey was completed over
the Nunyerry Project by Rockford Metals Ltd at 30 m sensor height
and 50 m line spacing for a total of 21,829 line kilometres.
|
Geology |
- Deposit type, geological setting, and style of
mineralisation.
|
- The Nunyerry North target area includes orogenic structurally
controlled quartz vein-related gold mineralisation within a
sequence of ultramafic komatiites and mafic rocks, juxtaposed by
regional shears and offset faults. The target hosts a 1.4 km long,
high-order surface soil anomaly, where rock chip sampling in 2021
returned peak high-grade results from quartz veins including 30.3
g/t Au, 21.1 g/t Au and 9.0 g/t Au; with additional sampling in
2022 delivering 8.81 g/t Au and 7.39 g/t Au. All significant
intercept tables include ‘nil’ results for drilling that failed to
intercept anomalous results.
|
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, including 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
plus 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.
|
- All relevant information for the Nunyerry North RC drill
program is summarized in the release Appendix - Table 1
|
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.
|
- All significant drill intercepts were calculated using a 0.3
g/t Au cut-off and up to 3 m consecutive internal dilution.
- No upper cutoff grades were applied.
- Gold is the only metal of economic significance reported.
|
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 (e.g., ‘down hole
length, true width not known’).
|
- Sectional interpretation confirms that the main veins
interpreted were intersected roughly perpendicular to the drill
holes.
- Estimates for true widths are between 75% and 100% of the
downhole intercept.
|
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.
|
- Refer to the body of the release for appropriate maps and
diagrams.
|
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.
|
- All significant drilling intercepts are provided in Table 1 in
the body of the main report.
|
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.
|
|
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.
|
- Plunge components are still open, and additional RC or diamond
drilling are considered to follow up
- Regional sampling is currently underway on the Tabba Tabba
Shear Zone to determine whether additional prospects can be
progressed towards reconnaissance drill testing
