Announcement PDF 10 November 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | | admin@critica.limited | www.critica.limited Critica Advances Jupiter Flowsheet — Gallium Demonstrated as Valuable By-Product within 1.8 Billion Tonnes Rare Earth Resource Critica’s MREP flowsheet achieves 63% Gallium leach recovery Following successful production of Critica’s first Mixed Rare Earth Product (MREP), metallurgical analysis confirms that ~63% of gallium oxide (Ga₂O₃) reports to leach solution within the same beneficiation-first flowsheet. The 1.8 Billion tonnes Jupiter Resource, averaging ~39 ppm gallium oxide (Ga₂O₃), containing approximately 70,000 tonnes of gallium — highlighting the strategic scale of the Company’s critical rare-earth and gallium endowment. Key Highlights • Scale: Jupiter’s 1.8 Bt Rare Earth Resource averages ~39 ppm Ga₂O₃ (indicative ~70 000t gallium oxide contained) - with localised zones exceeding 50 ppm • Leach recovery confirmed: ~63% of gallium reported to leach solution within Critica’s proven beneficiation-first rare-earth flowsheet, validated through MREP production • Integrated process advantage: Leach recovery occurs naturally within the existing REE circuit, with no change to flowsheet or project scope • Strategic context: China controls >98% of global gallium¹, under export-licence control since 2024, critical to next-generation chips and advanced defence systems • Next-phase work: Refine processes across GAVAQ, ANSTO and Minutech-AMML to define product pathways; further evaluation of germanium, scandium and iron byproducts underway • Jupiter Deposit: Tier 1 WA location with excellent access to existing infrastructure, very low impurities (Uranium & Thorium) Critica Limited (ASX: CRI) (“Critica” or “the Company”) is pleased to report results from recent metallurgical testwork and geochemical analysis undertaken as part of the Company’s Mixed Rare Earth Product (MREP) program. The work confirms that gallium oxide (Ga₂O₃) can be extracted as a potential by-product within Critica’s established beneficiation-first and hydrometallurgical flowsheet, delivering approximately 63% gallium recovery to leach solution (Refer Table 2 intermediate concentrate data). Note 1 - Source: Center for Strategic & International Studies, article: Beyond Rare Earths: China’s Growing Threat to Gallium Supply Chains accessed at www.csis.org accessed on 5 November 2025. 10 November 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | | admin@critica.limited | www.critica.limited The Company has also confirmed that its flagship Jupiter Deposit — Australia’s largest clay-hosted inferred rare-earth resource (1.8 Bt @ 1,700 ppm TREO at a 1,000 ppm cut-off) — averages ~39 ppm gallium oxide (Ga₂O₃), containing approximately 70,000 tonnes of gallium, highlighting the strategic scale of Critica’s rare-earth and gallium endowment. This outcome represents the next stage in Critica’s systematic flowsheet de-risking program. Gallium reports to the same leach solution from which Critica’s MREP is precipitated, confirming a clear line-of-sight to by-product recovery within the same process circuit. Additional elements, including germanium and scandium, have also been identified for further investigation. Critica’s CEO Jacob Deysel commented: “Jupiter continues to deliver scale, simplicity and strategic value. Metallurgical results indicate a clear line-of-sight to by-product recovery of gallium within the same process circuit that produced our first Mixed Rare Earth Product (MREP). Achieving ~63% gallium extraction into solution marks an important step in demonstrating co- product potential from within our existing process, without changing scope or strategy. This is not a pivot — it is a logical progression of Critica’s systematic flowsheet de-risking program. The strategic imperative for the West remains unchanged: it is no longer enough to access critical minerals — we must secure custody of supply. By proving the ability to recover gallium alongside rare earths, Critica strengthens its position within a Western-aligned, low-risk and technically validated supply chain.” Gallium (Ga₂O₃) The Jupiter Resource model confirms that gallium oxide (Ga₂O₃) occurs within both the clay and rare-earth phosphate minerals of the 1.8-billion-tonne resource (Figure 1: Ga₂O₃ grade distribution across the resource model). Average grades are ~39 ppm Ga₂O₃, with localised zones exceeding 50 ppm, equating to approximately 70 000 tonnes of contained gallium. This reflects the large-scale, homogeneous nature of the Jupiter system and provides strong confidence in grade continuity and deposit scale (Refer Table 1 for summary resource data). 10 November 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | | admin@critica.limited | www.critica.limited Figure 1 - Resource Model – showing Ga₂O₃ grade distribution across the resource model Metallurgical testwork undertaken as part of the Mixed Rare Earth Product (MREP) program confirmed that gallium behaves predictably within the existing beneficiation-first and hydrometallurgical flowsheet. Gallium records an upgrade factor of ~1.2× in the flotation concentrate, and subsequent testwork conducted by GAVAQ demonstrated that approximately 63% of gallium reports to the leach solution, corresponding to the leachable fraction hosted in the REE phosphates. This confirms a clear metallurgical pathway for potential co-product recovery, using the same processing route that produces Critica’s rare-earth products. Ongoing precipitation and recovery trials are now being designed within the Company’s pilot-plant program to define gallium product specifications and optimise extraction efficiency. (Figure 2: Schematic showing beneficiation-first flowsheet and gallium recovery pathway). 10 November 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | | admin@critica.limited | www.critica.limited Figure 2: Schematic of GAVAQ MREO Flowsheet - standard acid-bake and gallium recovery pathway 10 November 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | | admin@critica.limited | www.critica.limited Why This Matters – Strategic and Geopolitical Context • Integrated value: Potential gallium co-recovery may enhance economics without additional major process steps. • Execution simplicity: Same circuit that produced MREP; optimisation now focuses on selectivity, recovery and specification. • Market context: China supplies >98% of global gallium, which has been under export- licence control since 2024.1 • Strategic alignment: Strengthens a Western-aligned critical-minerals supply chain, enhancing resilience, optionality and strategic positioning. Critica Jupiter Development Pathway: From Validation to Value Creation Systematic flowsheet de-risking (50 kg → 400 kg → 3,000 kg pilot) • 23 Jan 2025 – Laboratory scale (50 kg): Initial flotation/beneficiation established proof-of-concept and confirmed Jupiter’s amenability to physical upgrading. • 28 May 2025 – Bulk sample dispatched (400 kg): Composite sent to GAVAQ (Vietnam) for scale-up testwork. • 29 Sept 2025 – Intermediate product validation: Bulk sample program delivered beneficiated concentrate (~95% mass rejection; 6–10× TREO uplift). Material was split to GAVAQ, ANSTO and Minutech-AMML for parallel hydromet programs, confirming flotation-to-leach integration and process consistency. • 1 Sept 2025 – Pilot plant commissioning (3,000 kg): Closed-circuit pilot at GAVAQ commenced commissioning to generate continuous operating data and additional concentrate for product optimisation. • 28 Oct 2025 – First MREP production: First Mixed Rare Earth Product (MREP) produced via standard acid-bake route (≈250 °C, ~4 h, H₂SO₄) followed by calcining. The product assayed 84% TREO at 78% recovery, with uranium and thorium well below International Atomic Energy Agency (IAEA) transport thresholds (Figure 3: Schematic showing beneficiate-first flow sheet now with MREP and Ga byproduct streams).

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.  Assay results from 541 Air Core (AC) and 77 Reverse Circulation (RC) drill holes for 31,798 m and 5,046 m respectively have been used in the reported Mineral Resource estimate. All drill holes have been reported previously to the ASX by Critica Limited (Critica), formerly Venture Minerals.  AC and RC drill cuttings were collected from the drill rig cyclone in 1 m intervals in plastic bags and arranged in rows on the drill pad for assay sampling. Composite samples were typically collected at 4 m intervals for AC holes and 2 m intervals for RC holes and up to 6 m intervals through barren overburden. Samples were collected from the 1 m bulk samples using a spear.  Drilling and sampling were supervised by suitably qualified Critica geologists.  Samples were submitted to the commercial laboratory ALS Geochemistry (ALS) for 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.).  AC and RC drilling presented in this report was completed by KTE Mining Services Pty Ltd.  AC drilling was completed using a Challenger RA 150 AC rig mounted on 4 x 4 MAN truck with an onboard 350 psi/750 cfm compressor. Drilling was conducted with a 90 mm diameter blade and all holes were drilled to blade refusal.  RC drilling was completed using DB450 and Schramm RC rigs with onboard 350 psi/1,150 cfm compressor and booster as necessary. Holes BRRC001-25 were completed to fresh rock with 5.5” face sampling hammer, BRRC030-81 were completed to blade refusal in saprock with a 4.5” blade. 10 November 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | | admin@critica.limited | www.critica.limited Criteria JORC Code explanation Commentary 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.  AC and RC sample return was visually monitored to ensure acceptable drilling recovery.  Bulk AC and RC sample weights were recorded on site for quality assurance and quality control (QAQC) purposes.  Majority of the holes intersected a shallow water table at or below the base of overburden, which only locally impacts sample recovery. 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.  All drill holes have been geologically logged by suitably qualified Critica geologists. Geological logging includes regolith, lithology, colour, grain size and visual estimation of mineral abundances.  Magnetic susceptibility was routinely conducted on all holes either on 1 m intervals or the assay intervals.  Hyperspectral mineralogy was routinely conducted by ALS Geochemistry on all assay samples subsequent to the initial BRAC036-039 discovery drilling program.  Geological logging was validated and cross-checked with geochemical and hyperspectral data for geological modelling.  The detail of the logging and data validation checks are considered sufficient to support a Mineral Resource estimation. Subsampling 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 subsampling 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.  Drill hole composites of 2–6 m were collected by spear from the bagged 1 m bulk samples.  Median assay sample weights across all AC and RC programs range from 1.7 kg to 2.6 kg with an overall median weight of 2.4 kg. The sample size is considered appropriate for the type of mineralisation and material sampled.  Certified reference material (CRM) and blanks were included in all submissions at a rate of 1 in 20.  Field duplicate samples were collected at a rate of 1 in 20 with at least one duplicate collected for each drill hole.  The average sample length is considered appropriate for clay hosted rare earth mineralisation. 10 November 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | | admin@critica.limited | www.critica.limited Criteria JORC Code explanation Commentary 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 (i.e. lack of bias) and precision have been established.  All samples were submitted to ALS Geochemistry, Perth (ALS). Samples were oven dried and then pulverised to an 80% passing 75 µm (PUL-25a).  Samples were assayed by ALS using Lithium Borate Fusion at 1,025°C followed by combined nitric, hydrochloric, and hydrofluoric acid digestion of the resultant glass bead and an ICP-MS finish for 32 elements including the full REE suite and Ga (ME-MS81) and four-acid digest (nitric, perchloric, hydrofluoric and hydrochloric) with ICP-AES finish for 34 elements including La (ME-ICP61).  Grind size checks averaged 94% passing 75 µm, exceeding the target grind size of 85–90% passing 75 µm.  99% of client CRM results reported within 3 standard deviations of their certified values for all rare earth elements (REEs) and yttrium. Ga reported with better than 3 standard deviations precision but a 22% negative bias with respect to the CRMs, indicating potential conservatism in the MRE Ga assay data set 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.  Critica assay data is as reported by ALS and has not been adjusted in any way.  Primary assay data is stored and documented using standard industry practices.  Assay results are compatible with the observed mineralogy.  Remnant assay pulps are held at Critica’s leased storage facility.  Umpire laboratory checks have been completed by both Intertek Genalysis (Maddington, Western Australia) and Bureau Veritas (South Australia) on 100 pulp samples. The results showed excellent data correlation for the REEs including yttrium in the target grade ranges.  Three RC holes were twinned with AC holes (8–23 m each). Downhole grade comparisons show suitably consistent thickness and grade between the twinned drill holes. Location of data points  Accuracy and quality of surveys used to locate drill holes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.  Specification of the grid system used.  Quality and adequacy of topographic control.  Drill hole locations were determined by handheld GPS with a nominal accuracy of better than 5 m.  All coordinates and maps presented in this report are in the Map Grid of Australia (MGA) Zone 50 GDA94 system.  Topographic control is derived from the catchment corrected Worldwide 3 arc second Shuttle Radar Topography Mission (SRTM) spot height data. 10 November 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | | admin@critica.limited | www.critica.limited Criteria JORC Code explanation Commentary 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.  This Mineral Resource is based on a 250 m x 500 m drilling grid over the entire Jupiter clay-hosted REE deposit, with 250 m x 250 m drill grid spacing over c. 85% of the deposit.  Three sites were twinned with RC within 20 m of an AC hole. Approximately 2 km of north and east drill traverses were drilled on c. 100 m AC and RC drill spacings, and one 750 m long east-west drill traverse was drilled on 50 m spacings to evaluate smaller scale continuity.  Drill spacing is considered appropriate to support an Inferred Resource estimation for a clay-hosted rare earth deposit. Assay results used in the Mineral Resource estimate are predominantly 4 m (ranging 2–6 m) in length composited from 1 m AC or RC sample intervals. 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.  All holes were drilled vertical, and mostly drilled to blade refusal in granitoid saprock. Several RC holes were hammered up to c. 50 m into fresh basement to investigate the saprock to fresh basement transition and primary REE mineralisation potential.  The dominant 250 m x 250 m regular north-south and east-west drilling grid is considered appropriate for the approximately horizontal clay-hosted REE mineralisation style.  Mineralisation is hosted within clay and clay saprolite regolith zones blanketing the deeply weathered Jupiter intrusion. The vertical holes and sub-horizontal geometry of the mineralised zones means that downhole thickness approximates true thickness. Sample security  The measures taken to ensure sample security.  The chain of custody for all Critica samples from collection through to dispatch was managed by Critica personnel.  Sample numbers are unique and do not include any location or interval information useful to non-Critica personnel.  The level of security is considered appropriate for exploration and resource definition drilling. 10 November 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | | admin@critica.limited | www.critica.limited Criteria JORC Code explanation Commentary Audits or reviews  The results of any audits or reviews of sampling techniques and data.  QAQC of procedures and data assessment were completed during drilling and at the end each major drilling program. A review of all data used in the Mineral Resource estimation was completed by Critica personnel. This included CRM performance, blank performance, sizing checks, field duplicate performance, umpire laboratory comparisons, drill hole twinning comparisons, and bulk density determination. A report was prepared by Critica and delivered with the data to SRK Consulting (Australasia) Pty Ltd (SRK) for the Mineral Resource estimation. – All CRMs show an overall low bias across majority of REEs. – Comparison of 100 samples with umpire laboratory results shows strong correlation. – Precision for field duplicate samples was considered good with 95.9%
