IRVINE DRILLING – HIGHEST ASSAY SINCE
DISCOVERY
STAWELL CORRIDOR – IRVINE PROJECT
• Assay results for hole RD048 (partial) confirm multiple occurrences of visible gold including
the highest-grade assay since the discovery of the Irvine Project in 2017.
• Record result within a greater 10m significant gold intercept zone that includes
disseminated sulphides within the Tenacity Hanging Wall Fault wall rock. Results received to
date from RD048 include:
○ 10m @ 12.1g/t Au from 413m
▪ Incl 0.3m @ 183g/t Au from 413m
▪ and 0.3m @ 64.3g/t Au from 413.8m
• Visible gold intercepts in hole RD048 continue to confirm potential for high grade lodes
within Irvine’s Resolution resource.
• Results are 200m north north-west of the visible gold intercept previously reported from
Irvine diamond hole RD046 and continue to reaffirm the Tenacity Hanging Wall Fault
structure to be high priority target with potential to deliver further significant high grade
gold intercepts and grow the Inferred Resource at the Irvine Project.
• Partial assay results also received from diamond drill hole RD047, which also intercepted
fine grained visible gold. Results to date include:
○ 0.7m @ 13.9g/t Au from 345.3m
○ 0.3m @ 25.2g/t Au from 409.25m
• Diamond drilling remains in progress at Irvine and is continuing to target key zones
immediately south of the Inferred Resolution Mineral Resource1

Cautionary Statement
The potential quantity and grade of the Exploration Target set out in Table 2 of this release is conceptual in nature
and was reported in 2021 (Irvine) and 2025 (St Arnaud). There has been insufficient exploration to estimate a Mineral
Resource, and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The Exploration
Target has been prepared and reported in accordance with the 2012 edition of JORC Code.
Samples collected from drill hole RD048 have been analysed utilising PhotonAssay methodology. Certified Reference
Material (CRM) for the purpose of Quality Assurance / Quality Control (QAQC) have been supplied by Onsite
Laboratory Services (OSLS). The Company confirms that to the best of its knowledge, the CRM supplied by OSLS are
suitable for use with PhotonAssay methodology and complies with QAQC expectation for PhotonAssay.
STAWELL CORRIDOR IRVINE PROJECT - DIAMOND DRILLING UPDATE
• Significant gold intercepts and numerous visible gold (VG) occurrences across multiple holes
(RD046, RD047 and RD048) intersected along of the newly identified Tenacity Hanging wall
Fault reaffirms the target’s potential to grow current resource.
• Gold mineralisation in hole RD048 confirmed as not solely associated with visible gold.
Substantial sulphide mineralisation (predominantly arsenopyrite) also returned elevated
gold grades immediately below the visible VG intercepts.
• Current drilling continues to step out and target additional high grade mineralisation
potential immediately south of the Resolution Inferred Resource.
• Results to date continue to support high-grade potential, further sampling and assaying of
the remainder of the holes is underway:
○ 10m @ 12.1g/t Au from 413m (inc. 0.3m @ 183g/t Au from 413m and 0.3m @
64.3g/t Au from 413.8m) - RD048
○ 0.7m @ 13.9g/t Au from 345.3m and 0.3m @ 25.2g/t Au from 409.25m – RD047

IRVINE PROJECT STEP OUT PROGRAM
Aureka’s maiden diamond drill program within the Stawell Corridor Irvine Project remains in
progress as part of its continuous exploration strategy. With the completion of drillholes RD045,
RD045W and RD046 drilling has successfully tested a 200m down-plunge extension of the
Resolution mineralised shoot. Drilling of RD047 and RD048 seeks to infill between the inferred
mineral resource and the step out drilling, targeting prospective geological settings for
permeability enhancement and gold mineralisation. This drilling further demonstrates
potential strike continuity to mineralisation along the Tenacity Hanging Wall Fault structure
immediately along strike of the Irvine JORC Resource.
The recent completion of drill holes RD047 and RD048 and their partial assay results highlights
the considerable upside potential of the Tenacity Hanging Wall Fault target to deliver further
high-grade mineralisation and grow the Irvine Inferred Resource beyond the current 304koz Au
@ 2.43g/t1
.
Drilling has been conducted by Trimac Drilling.
This release outlines partial assay results for RD047 and RD048 which follows the recent
reporting of full results from RD45W1 and partial results RD046 (visible gold sections).
RD048
Partial results from RD048 continue to demonstrate the presence of visible gold (VG) in the
Resolution mineralised shoot immediately down plunge to the southeast of the inferred
mineral resource (Figure 2). Results for RD048 are partial and the remaining assay results are
yet to be finalised. Significant results returned thus far include:
• 10m @ 12.1g/t Au from 413m
o Incl 0.3m @ 183g/t Au from 413m
o and 0.3m @ 64.3g/t Au from 413.8m
The Tenacity Fault was intersected at 413m as a 1.1m wide quartz vein containing significant
VG. The upper and lower bounds of the structure contained the majority of the VG returning
results of 0.3m @ 183g/t Au from 431m and 0.3m @ 64.3g/t Au from 431.8m.
Multiple significant quartz faults up to 30cm in size are identified within the intercept, leading
to local enhancements in grade, associated with increased alteration, quartz veining and
arsenopyrite occurrence.
The increased mineralisation in this intercept is interpreted to occur due to the intersection of
the Tenacity Fault with the contact between the basalt and sediments, leading to permeability
enhancement and increased fluid flow.

15 OCTOBER 2025
The Tenacity Fault intersection in RD047 was narrower than previously intercepted, resulting in
0.7m @ 13.9g/t Au from 345.3m. Mineralisation was associated with a narrow-laminated quartz
fault with abundant acicular arsenopyrite. The intercept confirms the fault is a conduit for high-
grade fluids and can lead to wider intercepts at more favourable structural settings.
VG was intercepted in a south-east dipping quartz vein footwall to the Resolution Fault,
resulting in 0.3m @ 25.2g/t Au from 409.25m. The vein contained multiple grains of fine-grained
VG with no other sulphides identified. This intersection represents the second VG footwall
intercept to the Resolution Fault, demonstrating potential for additional high-grade structures
that are yet to be thoroughly tested.
RESOLUTION GEOLOGICAL MODEL UPDATE
The maiden drill program has significantly improved the geological reinterpretation and
understanding of the plunging mineral controls and has assisted with delineating multiple
moderate west-dipping structures in the hanging wall of the main Resolution FW fault. Of the
west dipping hanging wall structures, the newly identified Tenacity Hanging Wall Fault is host
to several VG occurrences and has potential to rapidly transform into a considerable second
order structure with the capacity to deliver multiple higher-grade intercepts often associated
with VG, immediately south of the Inferred Mineral Resource.
Additional exploration drilling is being planned at Irvine to target potential high-grade
mineralised ore shoots extensions along extrapolations of the Tenacity Hanging Wall and
Resolution Foot Wall faults. Interpretated fault intersections support a southerly 20-25° plunge
to the mineralisation, as opposed to the previously interpreted 35°.
Ongoing drilling activities are infilling several key zones between the southern boundary of the
Inferred Mineral Resource and drilling outlined in this release (Error! Reference source not
found.2).
IRVINE GOLD PROJECT (STAWELL ZONE) - BACKGROUND
Aureka’s flagship Irvine Gold Project is located in Western Victoria. More than $13M has been
spent on the project since discovery.
Located within Victoria’s renowned Stawell Gold Corridor, a region with a rich history of high-
grade gold production and only 16km south of the operating Stawell Gold Mine, the Irvine
project features a JORC-compliant Mineral Resource of 304koz @ 2.43 g/t gold1
, with an
additional Exploration Target of 280 – 420koz @ 2–3 g/t2
.
The project area occupies the northern portion of the historic Ararat Goldfield and is hosted
within the Mooranambool Metamorphic Complex (MMC) of the Stawell Zone. The MMC is a
narrow belt of Cambrian turbidites and volcanic sequences with a dominant N-NW trend and

is characterised by tight folding, cleavage development and high-angle faults. The MMC is host
to the 5.3Moz Stawell Goldfield1
, including the currently operating multi–Moz Stawell Gold Mine.
Gold mineralisation at Irvine is associated with a package of steeply west dipping sheared basalt
(Simpson Basalt) and meta-sediments offset 50-80m from the eastern flank of a Cambrian
basalt dome (Irvine Dome) which is located on the hinge of an F2 antiform. Gold occurs on or
adjacent to the shear zone, typically on meta-basalt/meta-sediment contacts where the
rheological contrast provides an ideal locale for shearing.
Aureka has extended the work at the Irvine Project was used to compile the 2021 JORC Resource
which was based on:
• 42 structurally oriented diamond drillholes and 169 aircore, drill holes for a total of 23,465
metres at the Resolution prospect that have been drilled by Navarre Minerals (NML),
• 10 structurally oriented diamond drillholes and 195 aircore, drill holes for a total of 17,952
metres at the Adventure prospect that have been drilled by Navarre Minerals (NML),

Exploration Target – Irvine Project
On 30 March 2021, AKA (then trading as Navarre Minerals Limited ASX:NML) announced the
maiden gold Exploration Target at its flagship 100%-owned Resolution and Adventure projects
in Victoria, Australia. Notably, the Exploration Target was constrained to the current drill
footprint at Resolution and Adventure, as at the time these areas only contained sufficient
drilling to determine continuity and infer grade ranges. Significant potential exists to increase
the size of the exploration target with additional drill results beyond the Exploration Target
area.
The potential quantity and grade of the Exploration Target is conceptual in nature and therefore
is an approximation. There has been insufficient exploration to estimate a Mineral Resource,
and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The
ASX : AKA B R I N G I N G V I C T O R I A ' S G O L D T O L I F E 13
15 OCTOBER 2025
Exploration Target has been prepared and reported in accordance with the 2012 edition of the
JORC Code.
Summary of Relevant Exploration Data, Methodology, and Assumptions
Previously engaged consultants had, in conjunction with the Navarre Minerals personnel
generated an estimate of the Exploration Target for the Resolution and Adventure prospects.
These Exploration Targets represent the strike and depth/plunge extensions to the Mineral
Resources defined for both deposits. The results of this estimation are presented in Table 2 for
the combined Exploration Targets.
The Resolution and Adventure prospects are intersected by a predominantly west dipping
shear zone which broadly mimics the strike of the Irvine basalt dome. Gold occurs on or
adjacent to the shear zone, typically on meta-basalt/meta-sediment contacts where the
rheological contrast provides an ideal locale for shearing and mineralisation. The attitude of
the contacts also influences the shear geometry resulting in localised, high-grade gold shoots.
The Exploration Target was based on the interpretation of the following geology and
mineralisation data that had been collated as part of the 2021 MRE statement:
• 42 structurally oriented diamond drillholes and 169 aircore, drill holes for a total of 23,465
m at the Resolution prospect that have been drilled by Navarre Minerals (NML),
• 10 structurally oriented diamond drillholes and 195 aircore, drill holes for a total of 17,952
m at the Adventure prospect that have been drilled by Navarre Minerals (NML),
• 943 density measurements on mineralised diamond drill core, and the determined SG’s
were applied to the appropriate lithological units involved with the Exploration Target,
• surface geological mapping, costean data and diamond core geological logging,
• detailed LiDAR imagery,
• geophysical datasets including detailed ground magnetic and 3D induced polarisation, and
• wireframing and modelling of the Resolution and Adventure mineralised bodies.
For the Resolution prospect, the Exploration Target has been estimated based on the strike
continuity and down plunge continuity of the mineralisation defined by drilling and modelled
as part of the Mineral Resources. The extent of this strike and plunge continuity is considered
to be consistent with that evident in the Magdala deposit analogue to the north of Resolution,
as the mineralisation controls and style are consistent between the two deposits.
To determine the tonnage and grade ranges for the Resolution prospect Exploration Target, the
existing Mineral Resources as defined at Resolution was used as the base case in combination
with the geological understanding of the mineralisation model for Resolution. The northern
strike extents component of the Exploration Target has been based on the initial wide spaced
shallow AC drilling that extends approximately 900 metres to the north of the defined
Resolution mineralisation. The Consultants determined that the potential for a repeat of the
mineralisation defined in the upper parts of Resolution along strike is adequate for estimating
an Exploration Target that is within +/-20% of the Resolution open pit Mineral Resource. In
addition, the strong southerly plunge controls evident with the deeper parts of the Resolution
Mineral Resource have been used to guide the estimation of an Exploration Target down this
plunge direction at depth. This part of the Exploration Target has used the UG Mineral Resource
defined at an MSO cut-off grade of 1.4 g/t Au as a base with a +/-20% range applied for the
tonnage, grade and ounces.
ASX : AKA B R I N G I N G V I C T O R I A ' S G O L D T O L I F E 14
15 OCTOBER 2025
For the Adventure prospect, the Exploration Target has been estimated based on the wide
spaced exploration drilling that has been completed to date. The mineralisation as defined by
these drill results does not currently have adequate confidence to be classified as a Mineral
Resource. However, Mining Plus considers that the estimation of an Exploration Target is
possible for the mineralised extents that have been modelled. The ranges for tonnage, grade
and ounces have been estimated using the Adventure block model results reported at a 1 g/t
Au cut-off (Figure 10) for those estimated blocks remaining unclassified (that do not satisfy the
criteria of an Inferred Mineral Resource). A -20% and +30% range has then been applied to
determine the ranges required for reporting an Exploration Target*. It is important to note that
as these estimated blocks do not meet the requirements of a Mineral Resource, there is
increased likelihood of grade extrapolation, rather than interpolation, hence the application of
suitable tonnage, grade and ounce ranges for the Adventure Prospect Exploration Target. The
upper grade, tonnage and ounces range of +30% has been based on the presence of two of the
higher grade and thicker intercepts returned to date for Adventure being located at the base of
the Exploration Target.

Section 1 Sampling Techniques and Data
Criteria Commentary
Sampling techniques Diamond Core Drilling
• The diamond drill core samples were selected on geological
intervals varying from 0.20m to 1.0m in length.
• All drill core was routinely cut in half (usually on the right of the
marked orientation line) with a diamond saw and submitted for
analysis.
• Representative sample was ensured by a combination of
Company Procedures regarding quality control (QC) and quality
assurance/ Testing (QA). Certified standards and blanks were
routinely inserted into assay batches.
Drilling techniques Diamond Core Drilling
• Pre-collars were drilled to solid bedrock using an HQ3 drill bit
(93mm hole diameter) coring down to solid rock followed by
HWT casing diamond (114.3mm hole diameter)
• Diamond drilling of HQ3 (triple-tube) was undertaken where
possible to ensure maximum core recovery.
• RD046 reduced to NQ2 size (76mm hole diameter) from a depth
of 329.8m down-hole
• RD045W1 was wedged from RD045 at 431.91m depth and
drilled to NQ2 size.
• All drill core was orientated with a Reflex ACT III core orientation
tool then continuously marked with a line while on an angle iron
cradle.
• Upon completion of the primary hole a gyroscopic survey of the
hole was undertaken at a spacing of 1.0m along the length of the
hole.
Drill sample recovery Diamond Core Drilling
• All diamond core was logged for lithology, alteration, quartz
veining and to a standard acceptable for subsequent
interpretation capturing any core loss, if present, and recorded
in the database.
• All drill depths are checked against the depth provided on the
core blocks and rod counts are routinely carried out by the
driller.
• Core recovery for the areas sampled was generally good.
Logging • Geological logging of samples followed Company and industry
common practice. Qualitative logging of samples included (but
was not limited to); lithology, mineralogy, alteration, veining
and weathering.
• All logging is quantitative, based on visual field estimates.
Detailed diamond core logging, with digital capture, was
conducted for 100% of the core by Aureka’s geological team.

Sub-sampling techniques and sample
preparation
Diamond Core Drilling
• Detailed diamond core logging, with digital capture, was
conducted for 100% of the core by Aureka’s geological team.
• Half core was sampled from NQ and HQ diameter drill core.
• Company procedures were followed to ensure sub- sampling
adequacy and consistency. These included (but were not limited
to), daily workplace inspections of sampling equipment and
practices.
• Blanks and certified reference materials are submitted with the
samples to the laboratory as part of the quality control
procedures.
• No second-half sampling has been conducted at this stage.
The sample sizes are appropriate to correctly represent the
sought after mineralisation.
Quality of assay data and laboratory tests • Analysis for gold is undertaken Bendigo, VIC by 50g Fire Assay
with an AAS finish to a lower detection limit of 0.01ppm Au and
or Photon assay analysis down to 0.01ppm lower detection limit
using OSLS technique PE01S and PAAU02.
• It is the company’s intention for a 35 element Aqua Regia ICP-AES
analysis to be undertaken on selective samples to assist
interpretation of pathfinder elements.
• No field non-assay analysis instruments were used in the analyses
reported.
A review of certified reference material and sample blanks
inserted by the Company indicate no significant analytical bias or
preparation errors in the reported analyses. Internal laboratory
QAQC checks are reported by the laboratory and a review of the
QAQC reports suggests the laboratory is performing within
acceptable limits.
Verification of sampling and assaying • Samples will be verified by database consultants (MX Projects)
and Aureka geologists before importing into the drill hole
database.
• No twin holes have been drilled by Aureka during this program.
• Primary data was collected for drill holes using a company specific
logging template on a company laptop using lookup codes.
• The information was sent to a database consultant for validation
and compilation into a SQL database.
• Reported drill results were compiled by the Company’s geologists
and verified by the Exploration Manager and Managing Director.
• No adjustments to assay data were made.
Location of data points • All maps and locations are in UTM Grid (GDA94 zone 54).
• All drill collars are initially measured by hand-held GPS with an
accuracy of +3 metres.
• On completion of program, a contract surveyor picks-up collar
positions utilising a differential GPS system to an accuracy of
+0.02m.
• Topographic control is achieved via use of DTM developed from
a 2005 ground gravity survey measuring relative height using
radar techniques.
• Down-hole surveys were taken every 30m on the way down to
verify correct orientation and dip then multi- shots taken every
6m on the way out of the drill hole.
Data spacing and distribution • Variable drill hole spacings are used to test targets and are
determined from geochemical, geophysical and geological data
together with historic mining information.

• Drilling reported in this program is of an early exploration nature
and has not been used to estimate any mineral resource or ore
reserves.
• Refer to sampling techniques, above for sample compositing
Orientation of data in relation to geological
structure
• Exploration is at an early stage and, as such, knowledge on exact
location of mineralisation, in relation to lithological and
structural boundaries, is not accurately known.
• The drill orientation is attempting to drill perpendicular to the
geology and mineralised trends previously identified from
earlier drilling. Due to the early stage of exploration, it is
unknown if the drill orientation has introduced any sampling
bias. This will become more apparent as further drilling is
completed.
Sample security • Chain of custody is managed by internal staff. Drill samples are
stored on site and transported by Aureka employee’s or direct
contractors to the company to a registered laboratory in Bendigo
(On Site Laboratory Services (OSLS)).
• At the laboratory samples are placed into an assigned holding
crate and are then locked within the laboratory’s building before
being processed and tracked through preparation and analysis.
Audits or reviews • There has been no external audit or review of the Company’s
sampling techniques or data at this stage.
