Jupiter Product Samples Advance Offtake Discussions
High purity Mixed Rare Earth Oxide (MREO) and iron by-product samples
mark an important commercial milestone following optimisation and de-
risking of Jupiter’s processing flowsheet
Critica Limited (ASX: CRI) (“Critica” or “the Company”) is pleased to announce an important milestone at
its Jupiter Rare Earth Project, with the Company having now produced representative samples of high-
purity Mixed Rare Earth Oxide (MREO) and potential iron by-products.
The production of these samples represents the culmination of a systematic programme of metallurgical
optimisation and flowsheet de-risking at Jupiter. This work has progressively improved beneficiation
recovery, increased concentrate grade and mass rejection, reduced downstream reagent consumption
and demonstrated the repeatable production of high-quality rare earth products.
Importantly, the availability of physical product samples provides a tangible next step in the commercial
validation of Jupiter’s potential product pathways, and these samples support Critica’s ongoing
discussions and product evaluation with potential offtake and strategic counterparties.
Highlights
• Jupiter has produced representative MREO and iron by-product samples to
support commercial engagement of potential off-take partners
• Latest MREO sample grades 98.2% TREO, of which 28.4% comprises the highly
valued MagREO
• The potential iron by-product provides additional product optionality from
the Jupiter flowsheet, with high-grade iron concentrate sample grading 64.1%
Fe
• MREC sample production is in progress, which is expected to further broaden
the suite of Jupiter products available for off-take evaluation
• Product sample production follows optimisation and de-risking of the Jupiter
flowsheet, including ~81% MagREO recovery, ~14× beneficiation upgrade to
~3% TREO concentrate, ~95% mass rejection and ~30% lower sulphuric acid
consumption
• Critica is engaged in discussions with potential offtake and strategic
counterparties, with physical Jupiter MREO product samples available to
support product evaluation and commercial engagement
• The Jupiter and Mt Lindsay Scoping Studies remain on track for delivery in Q3
2026

Critica’s CEO Jacob Deysel commented:
“The production of representative MREO and potential iron by-product samples is an exciting milestone
for Jupiter. We have spent the past year systematically improving and validating the flowsheet, and we
have now reached the point where that work is translating into physical products that can support the next
phase of commercial engagement.
Importantly, this milestone is underpinned by a growing body of metallurgical work. We have improved
beneficiation recoveries, materially increased concentrate grade and mass rejection, reduced acid
consumption and repeatedly produced high-quality downstream rare earth products. Together, these
results continue to reduce technical risk and strengthen our confidence in Jupiter’s development
pathway.
Having representative products in hand is also important from a commercial perspective. We are engaged
in discussions with potential offtake and strategic counterparties, and these samples provide tangible
Jupiter products to support ongoing product evaluation.
With the Jupiter and Mt Lindsay Scoping Studies targeted for Q3, Critica is entering an important period as
we continue to advance the technical and commercial development of both projects.”
Mixed Rare Earth Oxide (MREO)
Jupiter has demonstrated the production of a high-purity MREO, with the latest product achieving 98.2%
TREO, of which 28.4% is Magnet Rare Earth Oxides (MagREO). The product contains strong concentrations
of the key Magnet Rare Earths neodymium, praseodymium, dysprosium and terbium, together with yttrium.

Table 1: MREO – Key Product Analysis
Note: Analysis shown relates to the MREO sample produced. MagREO comprises the four magnet rare earth oxides
Nd₂O₃, Pr₆O₁₁, Dy₂O₃ and Tb₄O₇. MagREO/TREO represents the proportion of total rare earth oxides comprising these
four magnet rare earth oxides. Final product specifications, including applicable grade ranges, remain subject to
ongoing product qualification and commercial discussions.
Production of a further MREC sample for product evaluation is also in progress. Jupiter has previously
demonstrated repeatable production of MREC at approximately 58% TREO, with the current programme
focused on producing a physical sample to complement the MREO and iron concentrate products
available for commercial engagement.
Iron Concentrate
In addition to its rare earth products, Jupiter has produced two potential iron by-products — a high-grade
magnetite concentrate and a hematite concentrate — demonstrating the potential to generate additional
products from the Jupiter flowsheet. The high-grade magnetite concentrate, which is the focus of this
announcement, provides a physical product to support engagement with potential customers on product
specifications and applications. The potential contribution of the iron products to the broader Jupiter
development case is being assessed as part of the Scoping Study.

Progressive De-Risking of the Jupiter Flowsheet
The production of physical product samples represents the culmination of a systematic programme to
optimise and de-risk the Jupiter processing flowsheet. Over the past year, Critica has progressively
demonstrated improvements across beneficiation, concentration and downstream processing, while
maintaining strong recovery of the high-value Magnet Rare Earths.
Key advancements include:
• ~81% MagREO recovery through beneficiation optimisation;
• ~14× upgrade to ~3% TREO concentrate with ~95% mass rejection, materially reducing the volume
of material reporting to downstream processing;
• ~30% reduction in sulphuric acid consumption through optimisation of the hydrometallurgical
circuit; and
• progressive improvement in MREO product quality, culminating in the latest MREO sample grading
98.2% TREO.
Together, these advancements have progressively strengthened the technical basis of the Jupiter
flowsheet, with the production of physical samples now providing the platform for the next phase of
product evaluation and commercial engagement.
Advancing Commercial Engagement
With physical MREO and iron by-product samples now produced, Critica is progressing discussions with
potential offtake and strategic counterparties regarding Jupiter’s potential product streams.
The samples provide tangible products to support ongoing engagement, including product evaluation and
qualification as discussions advance. MREC sample production is also in progress, which is expected to
further broaden the suite of Jupiter products available for evaluation.
These activities are progressing in parallel with the Jupiter Scoping Study as Critica continues to advance
both the technical and commercial development pathways for the Project.

Appendix One: JORC Code, 2012 Edition | ‘Table 1’ Report
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
Criteria JORC Code Explanation Commentary
Table
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.
• 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 Mixed Rare Earth Oxide (MREO)
and iron by-products referred to in this
announcement were produced from
beneficiated bulk samples taken from
35 Air Core (AC) and 8 RC drill holes
within the Jupiter Inferred Resource

of fine/coarse material.
• The bulk AC and RC samples were
visually assessed and weighed at the
drill rig. Recovery is considered
acceptable and representative.
10
Logging • Whether core and chip samples have

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

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.
• The material used in the reported
metallurgical test work represents 178
m from 35 AC and 8 RC drill holes
within the Jupiter Inferred Resource
footprint.
• The metallurgical samples were
collected by sampling scoop from the
bulk AC drill spoils which are stored in
large bags that have come directly off
the drill rig.
• One subsample of the homogenized
bulk sample was collected for head
assay prior to submission to the
metallurgical laboratory.
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.
• Head assaying of the constituent drill
samples and bulk metallurgical
composite was conducted at ALS
Geochemistry, Perth for a broad suite
of elements using industry standard
methods including REEs by lithium
borate fusion with ICP-MS finish.

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.
• The drill holes selected for the
reported metallurgical test work were
part of Jupiter exploration and
resource definition programs as
previously reported to the ASX and
available at http://critica.limited.

aggregations should be shown in
detail.
• The assumptions used for any
reporting of metal equivalent
values should be clearly stated.
• Metal equivalents have not been applied.
• Refer to previous ASX announcements for
relevant Jupiter project intersections and
assay results.
• Standard element to oxide conversion
factors have been used and TREO was
calculated on an unrounded basis.
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’
• The intersected clay and saprolite zones
blanket a weathered basement such that
downhole thickness approximate true
thickness.
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.
• Metallurgical sample locations are given in
Table 3.
• Refer to previous Critica announcements to
the ASX for block model plans and sections,
also available from https://critica.limited.
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.
• Refer to previous ASX announcements for
relevant Jupiter project drill intersections
and resource estimation.
Other
Substantive
Exploration
Data
• Other exploration data, if
meaningful and material, should
be reported including (but not
limited to): geological
• Refer to previous ASX announcements for
relevant Jupiter project drill intersections,
resource estimation, metallurgical and
