SIGNIFICANT GOLD INTERSECTIONS CONTINUE AT GOLDEN PLATEAU
• High-grade gold intersections returned from the Main, North and
East lodes, including:
GPS160 – 14.2m1 at 9.1g/t Au from 172.2m (Main lode)
GPS148 – 2.5m1 at 8.9g/t Au from 185.3m (Main lode)
GPS168 – 6.7m1 at 5.2g/t Au from 188.0m (Main lode)
GPS171 – 32.2m1 at 1.4g/t Au from 167.0m (Main lode)
GPS171 – 2.1m1 at 4.4g/t Au from 263.9m (North lode)
GPS169A – 18.5m1 at 2.4g/t Au from 220.8m (East lode)
• High-grades associated with remnant mineralisation adjacent to
historical stoping areas
• Geology model validated across all lodes tested, with
mineralisation consistently intersected at predicted positions
• Updated Mineral Resource estimate targeted for the first half of
FY27 to underpin an economic assessment of Golden Plateau
Established Australian copper-gold producer and explorer, Aeris Resources Limited
(ASX: AIS) (Aeris or the Company) is pleased to provide an update on activities at
the Golden Plateau deposit, located within the Company’s 100% owned Cracow
tenement package in Queensland.
Aeris’ Executive Chairman, Andre Labuschagne, said “The consistent performance
of our geological model continues to impress, with drill holes across the Main, North
and East lodes intersecting mineralisation at their predicted positions and delivering
some of our strongest results to date.
The high-grade intersection in GPS160 is a standout result and reinforces our growing
confidence in the remnant potential of Golden Plateau. Several of the higher-grade
intersections reported to date occur between and around historical underground
workings that targeted high-grade shoots. While these results are encouraging,

further drilling is required to determine the extent and continuity of the high-grade
mineralisation.
With the drill program nearing completion, we are well-positioned to update the
Golden Plateau Mineral Resource in the first half of FY27 and progress an economic
assessment of the project.”
Background
The Golden Plateau deposit is located within current mining leases, 1km north of the
Cracow Processing Facility and 2km east of the current underground mining
operations at the Western Vein Field (refer to Figure 1). Golden Plateau was the most
significant contributor to the Cracow goldfield, with approximately 850,000 gold
ounces2 produced between the 1930s to 1990s.
An updated geological interpretation and internal grade estimate was developed
across the Golden Plateau deposit2 based on detailed historical section
interpretations and more than 1,200 historical drill holes. A total of 33 mineralised
lodes have been interpreted and modelled, providing the foundation for the
current drill program. Following encouraging initial results3 the drill program was
expanded from 6,400m to approximately 14,000m, to test remnant mineralisation
across multiple lodes.

Drill Program Update
The 14,000m drill program is approximately 75% complete, with 55 drill holes
completed to date.
Assay results have now been received from an additional twenty-nine drill holes
targeting the Ferneyside, South, North, East and Main lodes. The majority of these
holes were designed to test remnant mineralisation surrounding and between
historical underground workings.
The geological interpretation continues to be validated by drilling, with drill holes
consistently intersecting modelled lodes at their predicted positions. Further drilling

will focus on defining the continuity and extent of higher-grade mineralisation within
the Main lode at depth, testing western extensions of the North lode, and testing
strike extensions to the East and Ferneyside lodes.

program at the Golden Plateau deposit. Note the section line is through the Main lode (GPS160)
referenced in this report.
Main Lode
5 | P a g e
The Main lode is characterised by broad zones of stockwork mineralisation
containing internal higher-grade shoots and was one of the most significant lodes
mined at Golden Plateau. The Main lode extends approximately 400m along strike
and 250m down-dip.
Drilling has intersected the lode and historical stope voids at their predicted
positions, confirming continuity of mineralisation throughout the interpreted
structural corridor. Several higher-grade intersections have been returned adjacent
to historical stoping areas (refer to Figure 3 and Figure 4). The extent of remaining
high-grade mineralisation is considered limited, as historical stoping focused on the
higher-grade portions of the Main lode and the number of stopes decreases with
depth.
Significant new intersections reported from the Main lode include:
• GPS160 14.2m4 @ 9.1g/t Au (including 4.1m4 @ 26.6g/t Au)
• GPS148 2.5m4 @ 8.9g/t Au
• GPS168 6.7m4 @ 5.2g/t Au
• GPS171 32.2m4 @ 1.4g/t Au
North Lode
Two drill holes targeting the Main lode were extended at depth to test a secondary
target referred to as the North lode. The drill results are encouraging with one high-
grade intercept reported. Historical drilling and underground development indicate
the potential for thicker mineralisation further to the west. The significant new
intersection returned from the North lode is:
• GPS171 2.1m4 @ 4.4g/t Au

Main lode and did not extend to the North lode.
8 | P a g e
East Lode
The Main lode splits into the East and South lodes at its eastern margin. The junction
of the three lodes is a zone of structural complexity that has generated broad
stockwork mineralisation, extending beyond the discrete lode structures mined
historically. Drilling completed to date has confirmed consistent gold mineralisation
across the East lode stockwork zone.
Significant assay intersections returned to date are primarily associated with
mineralisation adjacent to historical stoping areas and extending into the
surrounding stockwork, highlighting the potential to define additional mineralisation
beyond the historical mined areas through further drilling. Significant new
intersections reported from the East lode include:
• GPS169A 18.5m5 @ 2.4g/t Au
• GPS145 9.0m5 @ 1.5g/t Au
The East lode results continue to demonstrate continuity of mineralisation and
support the broader remnant mineralisation potential at Golden Plateau.
Ferneyside Lode
Drilling at the Ferneyside lode has focused on defining the extent of mineralisation
along the structure. The lode has a confirmed strike length of 150m and vertical
extent of approximately 100m (Figure 5).
At the northeastern margin of the Ferneyside lode, the quartz lode narrows and
transitions into thinner parallel quartz veins with limited potential. The southwestern
extent of the lode remains open and is an important target for future drilling,
particularly at the junction with the East lode.
Significant new intercepts returned for Ferneyside include:
• GPS146 4.3m5 @ 2.1g/t Au
• GPS165 1.3m5 @ 5.2g/t Au
The results confirm mineralisation across the defined strike length of the Ferneyside
lode. The focus will shift to testing the southwestern extensions and the potential
connection to the East lode.

grade (g/t) x estimated true width).

Moving Forward
The drill program remains on track for completion by end of June 2026, with assay
results being returned and prioritised. On completion of the drill program, the
Company intends to update the Golden Plateau Mineral Resource estimate in the
first half of FY27 to underpin an economic assessment of the project. The Company
remains focused on advancing Golden Plateau as a potential major ore source for
the Cracow Operation.

APPENDIX C:
JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data
Golden Plateau Remnants Drill Program
Criteria Commentary
Sampling techniques • All samples have been collected via diamond drilling.
• Most of the samples are collected at 1 metre intervals, with minimum lengths
of 0.4m and maximum of 1.2m. Samples taken are half core, due to the
program requirements for core retention and further test work. Sample
weights range from 1 kg to 4kg depending on sample length.
• Samples are sent to an independent and accredited laboratory (ALS
Brisbane). Samples less than 3kg are pulverised to a nominal 85% passing 75
microns. If sample weights exceed 3kg they are split via a rotary splitter and
an approximate 3kg sub sample is retained and pulverised. After
pulverisation a 50g sample is collected for fire assay.
• The sample size and sample preparation techniques are considered
appropriate for the style of mineralisation.
• Industry prepared standards are inserted in approximately 1 in 20 samples.
• The samples are considered representative and appropriate for this type of
drilling.
Drilling techniques • Drill holes are completed via diamond drilling with both HQ and NQ diameter,
dependent on ground competency and likelihood of intersecting historic
voids.
Drill sample recovery • The drillers record core recoveries on site at the drill rig. An Aeris Resources
field technician and/or geologist then checks and verifies them.
• Diamond drill core is pieced together as part of the core orientation process.
During this process, depth intervals are recorded on the core and checked
against downhole depths recorded by drillers on core blocks within the core
trays.
• Historically, core recoveries have been very high within and outside zones of
mineralisation. Diamond core drilled to date from the current drill program
has recorded high recoveries, which are in line with historical observations.
Void backfill has had very low recoveries due to the unconsolidated nature
of the fill.
14 | P a g e
Criteria Commentary
Logging • All diamond core is logged by an Aeris employee or a contract geologist.
• All diamond core is geologically logged, recording lithology, vein
quantity/texture/mineralogy, alteration, and weathering.
• All geological and sample data is captured electronically within LogChief
Software and uploaded to Aeris Resources licenced Datashed database.
• All diamond drill core is photographed and digitally stored on the Company
network.
• Core is stored in core trays and labelled with downhole meterage intervals
and drill hole ID.
Sub-sampling
techniques and sample
preparation
• All samples collected from diamond drill core are collected in a consistent
manner. Half core samples are cut via an automatic core saw, and half core
samples are collected on average at 1 metre intervals, with a minimum
sample length of 0.4 metre and a maximum length of 1.2 metre.
• Industry prepared independent standards are inserted approximately 1 in 20
samples.
• The sample size is considered appropriate for the style of mineralisation and
grain size of the material being sampled.
Quality of assay data
and laboratory tests
• All samples are sent to ALS Laboratory Services at their Brisbane facility for
sample preparation. Samples under 3 kg are pulverised to 85%, passing 75
microns. If samples are greater than 3kg, they are split prior to pulverising.
• Samples are assayed via a 50g fire assay charge (Au-AA26) using an AAS
finish. Au assaying is completed at the ALS Townsville laboratory. For this
program, Aeris are trialling Ag assaying via four acid digest and induced
coupled plasma (ME-ICP41) at the ALS Brisbane laboratory. This is to achieve
detection limits down to 0.2ppm Ag rather than the traditional fire assay (Ag-
AA47) used at Cracow for 1ppm detection.
• QA/QC protocols include the use of blanks, duplicates, and standards
(commercial certified reference materials used). The frequency rate for each
QA/QC sample type is 5%.
Verification of sampling
and assaying
• Logged drill holes are reviewed by the logging geologist and a senior
geologist. All geological data is logged directly into Logchief software at the
drill rig. The Logchief software is installed with Cracow specific logging codes.
The data is systematically transferred to the Datashed database. Validation
of the data is completed within Logchief and Datashed.
• Upon receipt of the assay data, the certified standards are checked against
anticipated values to assure the quality of the results. No adjustments are
made to the assay values.
Location of data points • Drill hole collar locations are surveyed via a qualified surveyor. Collar positions
were surveyed using a differential GPS (DGPS).
• Drill hole locations are referenced in MGA94 grid, sheet 56, for Golden
Plateau.
• Quality and accuracy of the drill collars are suitable for exploration results.
• The drill contractor completes downhole surveys taken during drilling with a
north-seeking Gyro tool. Surveys are taken at approximately 15 metres and
30 metres down hole and at 30-metre intervals thereafter.
Data spacing and
distribution
• The drill holes are exploratory in nature. They are testing conceptual
geological targets, the location and thickness of historic voids, and twinning
historic drill results of questionable validity.
Orientation of data in
relation to geological
structure
• All drill holes are designed to intersect the target at a high angle to the
interpreted structure.
• Each drill hole completed has not deviated significantly from the planned drill
hole path.
• Drill hole intersections through the target zones are not biased.
Sample security • Samples were collected by company personnel and delivered to the
laboratory via a transport contractor.
Audits or reviews • Data is validated when uploaded into the company's Datashed database.
• No formal audit has been conducted.

Table 1 Section 2 - Reporting of Exploration Results
Golden Plateau Remnants Drill Program
Criteria Commentary
Mineral tenement and
land tenure status
• The Cracow Operation is located immediately west of the Cracow township
in central Queensland. The Cracow Operation Exploration and Mining
Tenement package comprises 3 EPMs and 18 MLs covering an area of
approximately 889km2.
• The Cracow Operation Exploration and Mining tenements are wholly owned
by Lion Mining Pty Ltd, a wholly owned subsidiary of Aeris Resources.
• The drill program reported in this announcement at the Golden Plateau drill
program is located within ML3227, which is in good standing, and no known
impediments exist.
Exploration done by
other parties
• The Cracow Goldfields were discovered in 1932, with the identification of
mineralisation at Dawn, then Golden Plateau in the eastern portion of the
field. From 1932 to 1994, mining of Golden Plateau and associated trends
produced approximately 850koz of Au metal. Exploration across the fields
and nearby regions was completed by several identities including BP
Minerals Australia, Australian Gold Resources Ltd, ACM Operations Pty Ltd,
Sedimentary Holdings NL and Zapopan NL.
• In 1995, Newcrest Mining Ltd (NML) entered into a 70 % share of the Cracow
Joint Venture. Initially exploration was targeting porphyry type mineralisation,
focusing on the large areas of alteration at Ferneyside and Myles Corridor.
This focus shifted to epithermal exploration of the western portion of the field,
after the discovery of the Vera mineralisation at Pajingo, which shared
similarities with Cracow. The Royal epithermal mineralisation was discovered
in 1998, with further discoveries of Crown, Sovereign, Empire, Phoenix,
Kilkenny, and Tipperary made from 1998 up to 2008.
• Evolution was formed from the divestment of Newcrest assets (including
Cracow) and the merging of Conquest and Catalpa in 2012. Evolution
continued exploration at Cracow from 2012 to early 2020.
• Aeris Resources purchased the Cracow Operation (including the exploration
and mining tenements) in July 2020.
Geology • The Cracow project area gold deposits are in the Lower Permian Camboon
Andesite on the south-eastern flank of the Bowen Basin. The regional strike is
north-northwest and the dip 20° west-southwest. The Camboon Andesite
consists of andesitic and basaltic lava, with agglomerate, tuff and some
inter-bedded trachytic volcanics. The andesitic lavas are typically
porphyritic, with phenocrysts of plagioclase feldspar (oligoclase or andesine)
and less commonly augite. To the west, the Camboon Andesite is overlain
with an interpreted disconformity by fossiliferous limestone of the Buffel
Formation. It is unconformably underlain to the east by the Torsdale Beds,
which consist of rhyolitic and dacitic lavas and pyroclastics with inter-
bedded trachytic and andesitic volcanics, sandstone, siltstone, and
conglomerate.
• Mineralisation is hosted in steeply dipping low sulphidation epithermal veins.
These veins are composed of quartz, carbonate and adularia, with varying
percentages of each mineral. Vein textures include banding (colloform,
crustiform, cockade, moss), breccia channels and massive quartz, and
indicate depth within the epithermal system. Sulphide percentage in the
veins are generally low (<3%), primarily composed of pyrite, with minor
occurrences of hessite, sphalerite and galena. Rare chalcopyrite,
arsenopyrite and bornite can also be found.
• Alteration of the country rock can be extensive and zone from the central
veined structure. This alteration consists of silicification, phyllic alteration
(silica, sericite and other clay minerals) and argillic alteration in the inner

zone, grading outwards to an outer propylitic zone. Gold is very fined grained
and found predominantly as electrum but less common within clots of pyrite.
Drill hole information • All relevant information pertaining to each drill hole has been provided.
Data aggregation
methods
• Reported significant intervals vary depending on the style of mineralisation
intersected. There are discrete quartz lodes with relatively hard mineralised
boundaries. Criteria used to report this style of mineralisation includes a
minimum width of 0.4m, minimum Au grade 0.5g/t Au, maximum of 1m of
below cut-off material (<0.5g/t Au). There are also broad low-grade gold
stockwork domains. These intervals are based on the presence of quartz
veining. Gold grades are considered in the interval length. Internal
significant intersections within the broad low-grade gold stockwork zone
are reported using the same criteria as those noted above for discrete
lodes.
• Internal higher-grade intersections are reported applying a minimum
width of 0.4m, minimum Au grade 1.0g/t Au, maximum of 1m of below cut-
off material (<0.5g/t Au).
Relationship between
mineralisation widths
and intercept lengths
• Drill holes have been designed to intersect the mineralised structure at a high
angle where practicable and based on drill collar location constraints
surrounding the historic Open Pit and stockpiles.
• As a generalisation, drill hole intersections through the mineralised structure
at an acute angle (~30-60°).
• True thicknesses are estimated using general trends in the historic and current
drill data and guided by the historic void models and 1980s interpretative
level plans and cross sections.
Diagrams • Relevant diagrams are included in the body of the report.
Balanced reporting • The reporting is considered balanced, and all material information
associated with the drill results has been disclosed.
Other substantive
exploration data
• There is no other relevant substantive exploration data to report.
Further work • At the completion of the Golden Plateau drill program, an updated Mineral
Resource estimate that will be released FY27 H1.
