The purpose of this announcement is to clearly state that that gallium forms part of the existing rare-earth resource that was reported on the 11 February 2025 and is not being reported as a separate standalone resource. Updated announcement attached. Authorised by the Board of Critica Limited. Jamie Byrde Company Secretary 17 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 8 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. 17 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) (refer to table 6) — averages ~39 ppm gallium oxide (Ga₂O₃) (refer to table 7), 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 6 and 7 for summary resource data). 17 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.

INDEPENDENT MINERAL RESOURCE ESTIMATION DETAIL The following is a material information summary relating to the MRE that was reported on 11 February 2025, to now include Gallium, consistent with ASX Listing Rule 5.8.1 requirements. Further details are provided in JORC Code Table 1, which is included as Appendix B. Strategic Project Location and Accessible Infrastructure Discovered in late 2023, the Jupiter high grade clay-hosted rare earth deposit is part of Critica’s wholly owned Brothers project. The Brothers project spans approx. 1,500 km2 of semi contiguous granted tenure located approximately 550 kilometres northeast of Perth and 60 kilometres west of Mount Magnet in Western Australia (Figure 4). 17 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 Jupiter benefits from well-established infrastructure, enhancing its development potential. The project is strategically located within the Mt Magnet – Yalgoo area, a premier mining district of Western Australia. It is less than 10 kilometres from the Mount Magnet-Geraldton bitumen highway, providing direct access to local labour centres and the Port of Geraldton. Access to the project area from the bitumen highway is via unsealed tracks through the two crown pastoral lease stations that overlap the Brothers tenements. The terrain at Jupiter is flat, sparsely vegetated and facilitates year-round access. The mid-west gas pipeline runs parallel to the Mount Magnet-Geraldton highway, past the project site and transmission power lines run within 40 kilometres of the site to the south-west. A preliminary heritage survey was completed, and no Aboriginal cultural sites or materials were identified with the site deemed a low-risk area. Figure 4| Brothers and Jupiter Project Location Map Project History The Jupiter target was originally identified by geophysics with coincident aeromagnetic and gravity anomaly coupled with anomalous rare earth element results from two co-funded EIS drill-holes drawing Critica geologists into the area. First pass Air Core (“AC”) drilling of the Jupiter target along existing pastoral tracks was completed in June 2023 with every drill-hole reporting significant rare earth mineralisation within clay and saprolite zones. The grades and thicknesses reported were considered high compared to other known Australian clay-hosted rare earth deposits at the time. The discovery of the Jupiter REE deposit was 17 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 announced to the market in November 2023. Following the Jupiter discovery Critica conducted geophysical surveys (gravity and magnetics) and several RC and AC drilling campaigns which delineated an area of 40 square kilometres of high-grade, clay-hosted rare earth mineralisation. The consistent, broad zones of mineralisation up to 80 metres thick, with grades above 1,000 ppm TREO were identified. In 2024, two resource definition programs comprising 508 AC holes for 29,772 metres were drilled across the Jupiter project area. The first program defined the Jupiter mineralisation to a 500 x 250 metre line spacing. The second program infilled areas with thick intersections of >2,000 ppm TREO to a 250 x 250 metre drill spacing. The resulting information was utilised by SRK Consulting to produce an independent MRE for Jupiter. Geology and Geological Interpretation The Jupiter deposit is located within the Archaean Murchison Domain of the Youanmi Terrane, Yilgarn Craton. The Murchison Domain comprises narrow belts of supracrustal greenstones, the large layered mafic–ultramafic Meeline and Boodanoo suite intrusive complexes in the east, and voluminous granitic rocks emplaced between c. 2.7 Ga and 2.6 Ga. The extensive granitic rocks are divided into the Cullculli Suite (tonalite-trondhjemite-granodiorite), Big Belle Suite (tonalite-monzongranite), Tuckanarra Suite (granodiorite-monzogranite), Jungar (K-feldspar-porphyritic monzogranites) and the Bald Rock Supersuite (monzogranite and fluorite bearing alkaline granite). The Archaean basement throughout the Jupiter area is generally deeply weathered and extensively covered by Cenozoic alluvial and colluvial sand and gravel, laterite and lateritic gravels on breakaways and uplands. The Jupiter deposit and associated intrusion itself is completely concealed by alluvial and colluvial sand and hardpan within an area currently interpreted to be underlain by Big Bell Suite granitoids. Regolith thickness is up to 100 metres across the entire extent of the Jupiter geophysical anomaly that is extensively mineralised at the >1,000 ppm TREO and >39 ppm Ga2O3 level. The regolith comprises of three main zones which are described below in Table 1. Table 1 | Jupiter Regolith Profile description Regolith Thickness Description Cover Zone (SAND) 1-35m Alluvial and colluvial sand and gravel, extensively cemented and commonly laminated microcrystalline silica and lesser iron oxides. Gravel clasts comprise largely deeply weathered granitoids, and vein or pegmatite quartz, while the sand comprises iron- oxide stained rounded to sub angular quartz. A well washed quartz sand or grit is present in many areas at the base of the transported cover. Clay content typically increases with depth, and in areas without a distinct basal sand unit the boundary with the underlying in situ Clay Zone is difficult to visually distinguish. Hyperspectral logging shows a mixture of montmorillonite and kaolinite clay in the Cover Zone. Clay Zone (RCLY) <60m Kaolinitic clay (upper saprolite) with a variable content of sand-sized relict quartz reflecting protolith (which ranges from quartz-free syenite to granite). Colour ranges from white to dark ferruginous red brown, through to white or pink in the middle part of the Clay Zone (bleached) to yellow and brown in the lower part. An element of protolith control is also apparent with white and yellow kaolinite typically better developed over monzonite and granite protoliths with <20% ferromagnesium mineral content, and red brown clays developed over monzonite, syenite and alkali gabbro with >20% ferromagnesium mineral content. Ferricrete and silcrete zones are locally developed. Hyperspectral logging shows kaolinite is the dominant and commonly only volumetrically significant clay mineral. Saprolite Zone (RSAP) <40m Saprolitic clay with feldspar increasing down-hole, and depending on the protolith an increase of magnetite, biotite, amphibole, epidote and chlorite down hole towards fresh basement. Hyperspectral logging shows declining kaolinite and increasing nontronite and relict primary phases towards base of the saprolite. Relict igneous minerals and texture is increasingly evident through the Saprolite Zone. The upper contact between Saprolite and Clay zones is texturally difficult to visually pick in AC and RC cuttings but 17 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 Regolith Thickness Description the transition is usually conspicuous with a sharp increase from <1% K to several % K in the Saprolite Zone reflecting presence of relict potassium feldspar, a major rock former in most Jupiter protoliths. Bottom of hole (near fresh) and RC hammer drilling shows the basement beneath the Jupiter clay-hosted REE (-Ga) deposit comprises a zoned, heterogeneous medium to coarse grained intrusion that ranges from alkali gabbro and pyroxene syenite through monzodiorite and monzonite to granite. Geological logging and classification is complemented with a full-suite of bottom of hole multi-element geochemical data collected from every drill-hole. Mineralogy Clay-hosted REE, gallium and gangue mineralogy is typically very fine grained and required microanalytic techniques to resolve. Currently, mineralised regolith samples from Jupiter have been analysed by TIMA (Tescan Integrated Mineral Analyzer) to establish mineralogy (via a mineralogical library) and key grain size and liberation characteristics. Selected Jupiter TIMA samples were further analysed by LA-ICPMS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry) and EPMA (Electron Probe Micro Analysis) to verify and determine the compositions of the TIMA identified REE, gallium phases and gangue minerals. This microanalytical work shows the REE-phosphates Florencite-Gorceixite-Goyazite, Rhadophane-Monazite and Xenotime to be the dominant REE bearing phases in the Jupiter regolith. Florencite (REE)Al3(PO4)2(OH)5(OH)6 - Gorceixite (Ba,REE, Ga)Al3(PO4)(PO3OH)(OH)6 - Goyazite (Sr,REE)Al3(PO4)2(OH)5(OH)6 are hydrated phosphates with solid solution between barium, strontium and REE end members. Rhabdophane REE(PO4).(H2O) is a hydrated form of monazite REE(PO4), and it is likely that hydrated forms of the identified Xenotime (Y,HREE)PO4 will also be present. Dominant gangue minerals are quartz, magnetite, hematite, feldspar, kaolinite, epidote, biotite, muscovite, illite, chlorite, barite, rutile, titanite, ilmenite, Mn-oxides, zircon and apatite. LA-ICPMS and EPMA analysis also shows that gallium within the Jupiter deposit is hosted Gorceixite, Monazite-Rhabdophane and kaolinite. Drilling Techniques Air Core drilling was completed by KTE Drilling using a Challenger RA 150 Air Core rig mounted on a 4 x 4 MAN truck with inbuilt 600 CFM at 250 psi compressor. Drilling was completed using a 3.5” drill bit with blade. All holes were drilled vertically and to blade refusal. Reverse Circulation drilling was completed by KTE Drilling using a DB450 mounted on an 8 x 8 Scania truck with on board 1150/350 air compressor. All holes were drilled vertically to at least fresh rock with some holes extending up to 20 metres into the fresh rock. Diamond drilling was completed by DDH1 using a Sandvik DE840 truck mounted drill rig. Holes were drilled at -70o . Down-hole surveys were collected at 30 metre intervals. Results from the diamond drilling are still pending at the time of resource calculation and have not been included in the resource calculation. A summary of the drill-holes completed by Critica are outlined in Table 2.

The sticky nature of the clay materials and variability in fragment size precluded the effective use of cone or riffle splitting for sampling. Spear sampling was used to collect a subsample from each interval and used to prepare field composites that typically comprised of four metres (ranging 2 to 6m) weighing 2kg to 3kg. Duplicate samples were collected in sequence with the primary samples to monitor sampling consistency and ensure that the sampling method was suitable for this ore- type. No issues were identified. Sample Analysis and Methods Samples were dispatched to ALS (Canningvale and Wangara, WA) for geochemical testing. Samples weighing 2-3 kg, were processed using conventional sample preparation procedures, comprising oven-drying, crushing and then pulverising to a split of P95 passing 75 µm. For all samples a total of 34 elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Sr, Th, Ti, Tl, U, V, W and Zn) were analysed using a four-acid digest with an Inductively Coupled Plasma – Atomic Emission Spectroscopy (ICP-AES) finish (ME-ICP61). For samples exceeding La > 100 ppm and elevated P, a total of 32 elements (Ba, Ce, Cr, Cs, Dy, Er, Ga, Gd, Hf, Ho, La, Lu, Nb, Nd, Pr, Rb, Sc, Sm, Sn, Sr, Ta, Tb, Th, Ti, Tm, U, V, W, Y, Yb and Zr) were analysed by fusing a 0.1g pulverized sample with a lithium metaborate flux (ME-MS81). The resultant glass was dissolved in nitric, hydrochloric and hydrofluoric acid mixture. The solution was then analysed by Inductively Coupled Plasma – Mass Spectrometry (ICP-MS). For reporting purposes rare earth elements have been expressed in their oxide form. The factors used to convert the rare earth element grades to their oxide grades are outlined in Appendix B – Section 2. Quality Assurance and Quality Control Procedures The data collection programs include a comprehensive set of quality assurance and quality control (QAQC) procedures including twinned hole drilling, independent laboratory checks, and the insertion (by Critica) of standards, field duplicates and blanks into the primary submission batches. Field and laboratory sample weights were recorded and monitored. Periodic grinding checks were also conducted by the laboratory. Descriptions of the QAQC procedures and results are summarised below in Table 3. Table 3 | Summary of QAQC procedures and results QAQC Procedure Description Drill-hole twinning All drilling techniques can be susceptible to grade biases due to preferential material loss. Critica twinned 3 AC holes with RC holes and observed reasonable correlation in grade and in domain definition. The seven diamond core holes described above are proximal to existing RC and AC holes. Critica plans to use the assay data from these holes to assist with the validation of the RC and AC data once the laboratory test work has been completed. Field Duplicates The field duplicates comprised scoop samples collected from the composites at a nominal frequency of approximately 1 in 20. The duplicate dataset also includes 77 samples that were resubmitted as a separate batch to ALS. Critica used scatterplots, QQ plots, and precision plots to assess the duplicate datasets. The 17 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 QAQC Procedure Description QAQC graphs and summaries made available to SRK show acceptable performance. The scatterplots and QQ plots show no evidence of significant bias. The HARD (half average relative difference) plots show acceptable levels of precision have been achieved, with over 90% of the pairs reporting a HARD of less than 10% for most analytes. Spearing and scooping are generally not considered to be reliable sampling methods. However, the duplicate datasets do not show that these methods have introduced significant sampling error for the analytes of interest. Standards Standards were routinely included in the laboratory submissions at a nominal frequency of 1 in 20. A total of 5 different Standards were used, with 4 purchased from OREAS and 1 purchased from Geostats Pty Ltd. Summary control charts prepared by Critica show acceptable Standards performance, with relatively low failure rates and appropriate monitoring and response when failures are detected. Some biases are evident with most REE reporting slightly below their Certified values for all Standards. Most of the differences are less than 5%. Independent Laboratory Checks Critica submitted batches of pulp samples to independent laboratories for confirmatory testing. A batch of 100 pulp samples was sent to Intertek (Maddington) which assayed for a 45 element suite using lithium borate fusion with a ICP – OES/MS finish. The same batch of 100 pulps was then submitted to Bureau Veritas (South Australia) which completed a 32 element suite using lithium borate fusion with an ICP – MS finish. Analysis of the results showed very good agreement was achieved between the 3 laboratories, with no evidence of significant bias or precision differences. Blanks Blanks samples were inserted into the laboratory batches by ALS as part of their internal QAQC procedures at a nominal frequency of 1 in 20. The source, form, or certification of the blanks is not described. Several REEs reported at least 1 failure, with the highest rate being Lu (3.8%). Critica considers that the failures are likely due to analytical error and not sample contamination given that the higher failure rates are associated with elements with the lowest concentrations, and the failures for any given sample are generally limited to 1 or 2 analytes. Surveys All data used for resource estimation are reported using MGA94 Zone 50 coordinate system, with elevations based on the Australian Height Datum. The topographic dataset for the deposit region was acquired from open source 30 m gridded SRTM data. The collar locations were surveyed using handheld GPS to a reported accuracy of +/- 5m. SRK noted that all drillhole collar elevations were within 0.5m of the topographic surface elevations and no adjustments were applied. All of the RC and AC holes were vertical and relatively shallow and downhole surveying was not performed. The diamond core holes, which were all nominally angled at 70°, were downhole surveyed at 30 m intervals using gyro equipment. Density Determination Density data was derived from tests performed on core samples collected from seven diamond core holes drilled in 2024. The holes were drilled using PQ3 coring equipment through the weathered zone, stepping down to HQ3 once fresh rock was intersected. The drill-holes were broadly spaced over the strike extent of the deposit. Density tests were performed using the following techniques: • 388 Caliper density measurements were performed on competent core pieces ranging in length from 10 cm to 1 m. The dimensions were measured prior to oven drying at 105o C for 24 hours, with density calculated from the dry weights and estimated volume. • The core samples were processed using a Minanalyzer core scanner. This equipment uses laser scanning to estimate the volume of core samples stored in core trays. The core trays were weighed, oven dried, and then reweighed, with the density estimated from the dry core weight and estimated core volume. A total of 258 trays were scanned (equating to 704 metres) of which 131 tray measurements were deemed acceptable. • A total of 85 water immersion tests were performed. Sample sealing was not performed and the tests were conducted on fresh rock fragments only. 17 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 compiled and compared the density test results and noted acceptable agreement between the various test methods.
