Announcement PDF 28 October 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | F: +61 8 6500 9986 | admin@critica.limited | www.critica.limited Jupiter Delivers First High-Grade (84% TREO) Mixed Rare Earth Product, Further De-Risking Critica’s Flowsheet Critica Limited (ASX: CRI) (“Critica” or “the Company”) has achieved a major milestone with the successful production of an impressive, high quality Mixed Rare Earth Product (MREP) from the Company’s flagship Jupiter Deposit in Western Australia. The outstanding metallurgical results validate the Company’s beneficiation-first strategy and further de-risks Critica’s flowsheet, marking a clear transition from explorer to developer. Announcement Highlights • First Mixed Rare Earth Product (MREP) produced from Jupiter concentrate, assaying 84% TREO. • 78% recovery to Mixed Rare Earth Oxide (MREO) achieved, confirming high leach extraction. • Standard acid-bake process successful; parallel alternative leach programs underway at ANSTO and Minutech-AMML. • Very low impurities – uranium and thorium well below transport and handling thresholds1. • ~3,000 kg closed-circuit pilot at GAVAQ (Hanoi) now in commissioning phase. • Beneficiation testwork continues to deliver ~95 % mass rejection and 6–10× grade uplift, supporting a simple, capital-efficient flowsheet. • These results prove that Critica can produce a high-grade Mixed Rare Earth Product (MREP). The first unoptimised high-grade MREP from Jupiter achieved 84% TREO with 78% recovery to Mixed Rare Earth Oxide (MREO). This demonstrates that beneficiated Jupiter concentrate can be leached using conventional, scalable hydrometallurgy, yielding a high-purity oxide product (see Figure 1). The result represents a major technical step forward, advancing Critica’s pathway toward pilot-scale operations, Scoping Study inputs, and product specification definition. 1 One of the world’s largest and cleanest clay-hosted deposits. 28 October 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | F: +61 8 6500 9986 | admin@critica.limited | www.critica.limited The metallurgical work forms part of Critica’s broader Mixed Rare Earth Products (MREP) program, encompassing both oxide (MREO) and carbonate (MREC) specifications. The initial oxide product was produced via a standard acid-bake route under supervision of the Centre of Science and Technology of Minerals and Environment (GAVAQ) in Hanoi, Vietnam (see Figure 2). The Magnet Rare Earth Oxide (Nd, Pr, Dy, Tb) component represented ~23% of total REO content, reinforcing Jupiter’s strong magnet-REE bias — the value driver for EV, AI, Data Centres, renewable and defence supply chains. The Jupiter Project is Australia’s largest Magnet Rare Earth resource hosted in clay and these results will be globally significant for consideration of Western sourced rare earth supply chain development. Parallel hydrometallurgical programs at the Australian Nuclear Science and Technology Organisation (ANSTO) and Minutech – Australian Minmet Metallurgical Laboratories (AMML) are exploring alternative leach routes to further optimise MREP chemistry. Critica’s CEO Jacob Deysel commented: “This first unoptimised Mixed Rare Earth Product is a pivotal step for Critica. Our metallurgical results confirm that beneficiated Jupiter concentrate can be successfully leached using conventional, scalable processing to produce a high-grade oxide product. With beneficiation proven, MREP achieved, and pilot commissioning underway, we are moving decisively from explorer to developer. Our focus now is optimisation, product specification, and engagement with prospective offtake and strategic partners as we continue building a credible, low-cost, Western-aligned rare earth supply chain anchored in one of the world’s largest and cleanest clay-hosted deposits.” Figure 1: Initial Mixed Rare Earth Product (oxide) 84% TREO 28 October 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | F: +61 8 6500 9986 | admin@critica.limited | www.critica.limited Why This Matters – Flowsheet De-risked This milestone bridges beneficiation and hydrometallurgy, confirming the integrity of Critica’s integrated flowsheet. It demonstrates and supports the Critica model of: • Simplicity: Beneficiate first to reduce mass and cost; leach an upgraded hydromet feed product (intermediate concentrate) to saleable MREP specifications. • Scale: Australia’s largest clay-hosted magnet-REE resource base underpins long-life optionality. • Speed: Pilot commissioning now; data flows directly into product specification and Scoping Study workstreams.

The pilot will enable continuous operation to optimise upgrade and recovery performance, generate larger volumes of concentrate for downstream hydrometallurgical testwork and provide data for Critica’s upcoming Scoping Study. Figure 3: GAVAQ Pilot Plant – cold commissioning of Pilot Plant Progression Pathway – From Laboratory to Pilot Critica’s Jupiter flowsheet development has advanced through a disciplined scale-up program, validating performance and de-risking the process at each stage: • Laboratory Scale (23 January 2025): Initial flotation and beneficiation trials on 50 kg of sample established proof of concept and confirmed Jupiter’s amenability to physical upgrading. • Bulk Sample (28 May 2025): Dispatch of a 400 kg composite to GAVAQ in Vietnam confirmed consistent ~95 % mass rejection and 6–10× TREO grade uplift across all ore types ( See ASX announcement 29 September 2025 – Consistent Bulk Sample Results Strengthen Jupiter Pathway). 28 October 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | F: +61 8 6500 9986 | admin@critica.limited | www.critica.limited • Intermediate Product Validation: This bulk sample produced intermediate beneficiated concentrate that was divided between GAVAQ, ANSTO and Minutech–AMML to support parallel hydrometallurgical development. GAVAQ has since delivered the first Mixed Rare Earth Oxide (MREO) from this intermediate concentrate, validating the integrated beneficiation-to-leach pathway and confirming parallel progress across all laboratories. • Pilot Plant (1 September 2025): Commissioning of the 3,000 kg closed-circuit pilot plant at GAVAQ is now underway. This program will optimise upgrade and recovery performance, produce additional concentrate for MREP optimisation, and generate key inputs for Critica’s Scoping Study and early offtake discussions. The bulk sample completed in May 2025 therefore marks the critical bridge between laboratory trials and pilot operations—demonstrating that ore from Jupiter can be beneficiated, leached, and converted to a high-grade oxide product through scalable, conventional processing routes. Next Steps • Commission and operate the closed-circuit pilot at GAVAQ (Q4 ’25 – H1 ’26). • Conduct parallel hydrometallurgical optimisation at GAVAQ, ANSTO and Minutech-AMML to finalise bake and leach parameters (Q4 ’25 – H1 ’26). • Define final MREP/MREO product specifications (H1 ’26). • Incorporate pilot and hydromet results into Scoping Study inputs (H1 ’26). • Initiate Pre-feasibility Study (H2 ’26). • Advance offtake and strategic engagement as product specifications are finalised (ongoing). About GAVAQ Established in 2004, the Centre of Science and Technology of Minerals and Environment (GAVAQ) in Hanoi is a Vietnam-based mineral-processing and metallurgical engineering firm with nearly two decades of experience in beneficiation and plant design. The company provides end-to-end capability from feasibility to full-scale circuit delivery and equipment supply. Vietnam itself hosts significant rare- earth resources and has deepening expertise in REE processing, making GAVAQ’s involvement particularly valuable to Critica’s flowsheet development and pilot-scale programs. 28 October 2025 ASX: CRI CRITICA LIMITED Level 2, 16 Altona Street, West Perth, Western Australia ABN 51 119 678 385 | T: +61 8 6279 9428 | F: +61 8 6500 9986 | admin@critica.limited | www.critica.limited Glossary of Terms • TREO (Total Rare Earth Oxides): Total content of all rare earth oxides in a sample. • MREP (Mixed Rare Earth Products): Critica’s collective term covering both Mixed Rare Earth Carbonate (MREC) and Mixed Rare Earth Oxide (MREO) specifications.
