Announcement PDF 16 July 2025 ASX: CRI CRITICA ADVANCES JUPITER’S BENEFICIATION WORK DELIVERING OUTSTANDING MAGNET AND STRATEGIC HEAVY RARE EARTH GRADES The Board of Critica Limited (Critica or the Company) is pleased to report the next stage of metallurgical test work results for its flagship Jupiter Project. Building on the Company’s February 2025 metallurgical program, this latest phase incorporates the full suite of rare earth elements — including the first focused analysis of Heavy Rare Earth Oxides (HREO) — and confirms the project’s ability to generate high-quality, upgraded material using conventional, low-cost beneficiation. Test work was conducted by the Centre for Science and Technology of Mineral Resources and Environment (CSTMRE) in Vietnam. Results demonstrate successful beneficiation of Jupiter’s clay-hosted mineralisation through Wet Low Intensity Magnetic Separation (WLIMS) and froth flotation, producing a beneficiated grade of 15,000 ppm (1.5%) Total Rare Earth Oxides (TREO), including 1,400 ppm HREO and 5,200 ppm combined NdPr+HREO (refer Table 1) with a 95% mass reduction. HIGHLIGHTS • Australia’s largest clay-hosted REE resource: 1.8 Bt @ 1,700 ppm TREO Inferred Resource, including 500 Mt @ 2,200 ppm TREO. • Globally significant scale: Jupiter resource grade, size and thickness comparable to the world’s top clayhosted rare earth deposits. • Breakthrough beneficiation of clay-hosted REE mineralisation reduces potential leach feed by 95% and returns 15,000 ppm (1.5%) TREO including: o 3,990 ppm Magnet Rare Earth Oxides (MREO) o 1,400 ppm Heavy Rare Earth Oxides (HREO) o 5,200 ppm combined NdPr + HREO • Clean metallurgy: Exceptionally low uranium and thorium content across the resource. • Potential premium 67% Fe iron ore by-product from the REE beneficiation process. • Strategic location proximity to established infrastructure and processing hubs, including Lynas (Mt Weld) and Iluka (Eneabba). • District-scale potential: Jupiter is only one of six clay-hosted REE discoveries within the Brothers Project footprint representing <3% of the Project area. • Strong development potential: Positioned to support Australia’s strategic REE supply ambitions. The successful upgrading of the strategic, geopolitically important and high-value HREOs marks an important step forward for the Jupiter Project. These results confirm Jupiter’s capacity to deliver a valuable mix of strategic rare earth elements, including both light (Nd, Pr) and heavy (Dy, Tb) oxides, supporting its development as a significant contributor to the magnet REE supply chain. As Australia’s largest known and highest grade clay-hosted rare earth deposit, with a 1.8 billion tonne resource envelope, Jupiter has demonstrated potential to host globally significant HREO zones. In response to these results, Critica will now optimise its resource model to prioritise these HREO-rich zones, with results expected to be released in the coming weeks. Ongoing metallurgical test work is focused on refining beneficiation processes to maximise grade and recoveries, and the production of beneficiated material suitable for leach testing and rare earth carbonate production. Additional work is also assessing the potential production of premium iron ore from the REE processing stream.

This provides Critica with a significant competitive advantage potentially translating to lower CAPEX/OPEX, reduced environmental impact, faster permitting, and alignment with the Company’s strong ESG focus (refer Critica release 23 January 2025: “First Pass Metallurgical Testwork Delivers 830% Rare Earth Upgrade”). CEO Jacob Deysel said: “This next phase of test work confirms Jupiter’s ability to deliver upgraded rare earth concentrates with a meaningful NdPr and HREO component, advancing us further along our development path. It reflects a technically sound, low-cost beneficiation route and supports our vision of transitioning Critica from explorer to near-term developer. One of the most important—yet underappreciated—outcomes is the exceptional 94.5% mass reduction achieved. This dramatically lowers the volume of material requiring chemical processing, which in turn reduces capital and operating costs, minimises environmental impact, and enhances permitting and ESG outcomes. This is a fundamental advantage that directly strengthens project economics and our broader development strategy. Jupiter’s sheer scale, grade, and location remain critical advantages, but it’s our ability to now show tangible progress toward a commercial outcome that sets us apart. This is another step in unlocking the project’s value with speed, discipline, and a sharp commercial focus.” Details of the Latest Metallurgical Results Initial testwork demonstrated strong beneficiation potential using a simple, two-stage flowsheet. An early-stage, unoptimised recovery of 45% was achieved using conventional Wet Low Intensity Magnetic Separation (WLIMS) followed by rougher froth flotation — providing a solid baseline for further optimisation. The process delivered a significantly upgraded product grading: • 15,000 ppm (1.5%) Total Rare Earth Oxides (TREO) • 3,990 ppm Magnet Rare Earth Oxides (MREO) • 1,400 ppm Heavy Rare Earth Oxides (HREO) • 5,200 ppm combined NdPr + HREO Importantly, this was achieved with a 95% mass reduction, supporting efficient downstream processing and transport economics. The WLIMS stage also generated an iron-rich fraction grading 67% Fe, indicating potential for a premium iron ore by-product from the same beneficiation stream.

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. 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..). • Method of recording and assessing core and chip sample recoveries and results assessed.
