CaldasSouth Results Identify Second Potential ISR Area
Highlights
• Second potential ISR area identified: total and magnesium sulphate leach assays identify a
laterally continuous ionic adsorption clay (IAC) rare earth system at Caldas South
• Supports Axel’s ISR strategy: Caldas South has the characteristics targeted for low-cost, low-
impact in-situ recovery (ISR)
• Standout soluble leach results: 6m at 921ppm soluble TREO (35% MREO), including 1m at
1,542ppm soluble TREO (38% MREO)
• Continuous soluble mineralisation: ionic rare earth mineralisation occurs in an
exchangeable form over continuous down-hole intervals, a key geological requirement for ISR
• Broad, near-surface system: total assays define extensive clay-hosted mineralisation from
surface, within deeply weathered granitic and gneissic saprolite
• Complements 572Mt REE Caladão Project: Caldas South has the potential to follow the
staged ISR pathway being developed at Woolrich, which remains Axel’s primary focus
Axel REE Limited (ASX: AXL, FSE: HN8, Axel or the Company) announces rare earth elements (REE) assays
and magnesium sulphate ionic leach results from auger drilling at the Caldas South Block, located along the
south-western margin of the Poços de Caldas Alkaline Complex in Minas Gerais, Brazil.
These results identify Caldas South as a second area for potential in situ recovery (ISR) pathway within Axel’s
portfolio. The Company’s immediate focus remains its flagship Woolrich ISR deposit within the 572Mt REE
Caladão Project, where recent column leach testwork has successfully demonstrated strong REE ISR
amenability. Those results underpin the upcoming exploratory ISR field trials at Woolrich and the low-
impact, lower-capital-intensity ISR development model the Company is targeting.
Managing Director, Patience Mpofu, commented:
“These results establish Caldas South as a potential second ionic rare earth district
within Axel’s portfolio. The drilling confirms broad, near-surface mineralisation, and the
leach results show that a meaningful portion of that inventory sits in an exchangeable
ionic form – the key characteristic we look for in a potential ISR target. Encouragingly, the
mineralisation is hosted in weathered granitic and gneissic saprolite outside the central
alkaline complex, a different geological setting that warrants dedicated permeability and
hydrogeological assessment.
Woolrich remains our most advanced project and primary focus. Our objective is to build
a portfolio of ionic rare earth projects capable of progressing through a common,
modular and potentially low-impact ISR development pathway, and Caldas South adds
meaningful scale and optionality to that strategy.”

Total and Soluble Assays: Two Complementary Measures
Two assay types are reported. Total rare earth oxides (TREO) define the abundance and continuity of REE
mineralisation within the clay profile, while magnesium sulphate leach assays measure the soluble,
ionically-adsorbed rare earth oxides (SREO) fraction that is potentially recoverable by ISR. Because ISR
relies on solution progressively exchanging adsorbed rare earth ions through a permeable clay profile,
continuity of the soluble fraction, rather than total grade alone, is an important geological characteristic.
Total assays therefore define the geological footprint of the system, while SREO assays support assessment
of its potential suitability for ISR.

Strong Ionic Adsorption REE Results
The initial magnesium sulphate leach programme conducted by SGS Laboratories confirmed thick, near-
surface intervals containing high concentrations of ionically adsorbed rare earths at Caldas South. Key
results include 6m @ 921ppm STREO (35% MREO) from 3m in CAL-AUG-125, including 1m @ 1,542ppm
STREO (38% MREO) from 5m.
These soluble grades compare favourably with soluble grades reported from other ionic clay projects being
developed internationally. Ionic leach testwork has so far been completed on selected representative auger
holes.
Caldas South Block
The Company completed an initial programme of 28 auger holes for 315 metres across seven Exploration
Licences covering 12,008.69 hectares on the south-western margin of the Poços de Caldas Alkaline
Complex (Figure 3). The licences overlie the Varginha-Guaxupé Complex, where granulitic basement, biotite
gneiss and syeno-monzogranite form the principal bedrock beneath the weathered profile targeted by the
programme.
These results identify Caldas South as a potential second mineralised district capable of progressing
through the technical pathway being developed at the 572Mt REE Caladão Project. Subject to confirmation
of permeability, hydraulic continuity, containment and recoverability, Caldas South could provide an
additional ionic REE system within the broader Axel portfolio.

Leaching assay results
Following the review of total rare earth assay results, samples from 10 selected auger drill holes at the
Caldas South Block were submitted to SGS for magnesium sulphate leach testing. The programme was
designed to evaluate the SREO component and assess the potential for ionic adsorption clay-style
mineralisation. Results returned several intervals above the 200 ppm SREO cut off, with the strongest result
from CAL-AUG-125 returning 6 m @ 921 ppm SREO. These results compare favourably with reported soluble
grades from several Chinese ionic adsorption clay deposits, including Longnan Zudong REE Mine in Gannan,
Jiangxi - the largest regolith-hosted HREE deposit in the world1
. Further drilling and metallurgical testwork
will be required to confirm the continuity, scale and recoverability of the mineralisation.

About Axel REE
Axel REE is a critical minerals exploration company which is primarily focused on developing the Caladão
REE-Gallium and Caldas REE Projects in Brazil, the third largest country globally in terms of REE Reserves.
Axel is advancing a low-cost, modular development concept at Caladão based on in situ recovery (ISR) of
ionic clay-hosted rare earth mineralisation using magnesium sulphate leaching. This approach aims to
minimise surface disturbance and capital intensity by deploying modular hydrometallurgical plants within
wellfields. In parallel, Axel is progressing metallurgical programs to unlock additional value from gallium and
scandium within the near-surface oxidised profile.

JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
Criteria JORC Code explanation Commentary
Sampling
techniques
• Nature and quality of sampling (eg 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 pulverized 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.
• Auger holes
• At each drill site, the surface was thoroughly
cleared. Soil and saprolite samples were
gathered every 1 meter with precision, carefully
logged and photographed. Each sample was then
sealed in plastic bags and clearly labelled for
identification.
Drilling
techniques
• Drill type (eg core, reverse circulation,
open-hole hammer, rotary air blast, auger,
Bangka, sonic, etc) and details (eg 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).
Augerdrilling
• A motorized 2.5HP soil auger with a 4” drill bit,
reaching depths of up to 20 meters, was used to
drill. The drilling is an open hole, meaning there is a
significant chance of contamination from the
surface and other parts of the auger hole. Holes are
vertical and not oriented.
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
Auger drilling
No recoveries arerecorded. Recovery is not routinely
measured for this style of auger drilling.
• No relationship is believed to exist between
recovery and grade.

material.
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.
The geology was described in a Company´s
geological logging facility by the project geologist
- logging focused on the soil (humic) horizon,
saprolite, and fresh rock boundaries. The depth of
geological boundaries is honored and described
with downhole depth – not meter by meter.
Other important parameters for collecting data
include grain size, texture, and color, which can
help identify the parent rock beforeweathering.
All drilled holes have a digital photographic record.
The log is stored in a Microsoft Excel template with
inbuilt validation tables and a pick list to avoid data
entry errors.
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.
Sample preparation (drying, crushing, splitting
and pulverising) is carried out by SGS laboratory,
in Vespasiano MG, using industry-standard
protocols:
1. total assay by sodium metaborate,
• dried at105°C
• the saprolite is just disaggregated with
hammers
• Riffle split sub-sample
• 250 g pulverized to 95% passing 150
mesh, monitored bysieving.
2. For leaching with magnesium sulfate,
• dry sieving at 4mm (SCR33) discharging
the retained material
• <4mm homogenized
• 40g aliquot selectionfrom pulppacket
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 (eg standards, blanks, duplicates,
external laboratory checks) and whether
acceptable levels of accuracy (ie lack of
bias) and precision have been established.

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.
The UTM SIRGAS2000 zone 23S grid datum is used for
current reporting. The auger collar coordinates for the
holes reported are currently controlled by hand-held
GPS.
Data

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.

No resources are reported.
The drilling density is appropriate for reporting
Exploration Results but is insufficient for Mineral

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.
All auger holes were drilled vertically, which is
deemed the most suitable orientation for this type
of supergene deposit. These deposits typically
have a broad horizontal extent relative to the
thickness of the mineralised body, exhibiting
horizontal continuity with minimal variation in
thickness.
Given the extensive lateral spread and uniform
thickness of the deposit, vertical drilling is optimal
for achieving unbiased sampling. This orientation
allows for consistent intersections of the
horizontal mineralised zones, providing an

accurate depiction of the geological framework
and mineralisation.
No evidence suggests that the vertical orientation
has introduced any sampling bias concerning the
key mineralised structures. The alignment of the
drilling with the deposit's known geology ensures
accurate and representative sampling. Any
potential bias from the drilling orientation is
considered negligible.
Sample
security
• The measures taken to ensure sample
security.
All samples were collected by field personnel and
securely sealed in labeled plastic bags to ensure proper
identification and prevent contamination. All samples
for submission to the lab are packed in plastic bags (in
batches) and sent to the lab where it is processed as
reported above.
The transport from the Caldas Project to the SGS
laboratory in Poços de Caldas-MG was undertaken by
field
personnel.
Audits or
reviews
• The results of any audits or reviews of
sampling techniques and data. No independent audit has beencompleted.
