Critica Delivers ~97% TREO MREO at Jupiter

Why It Matters

Higher TREO purity and strong magnet‑rare‑earth recoveries improve project economics and bolster Australia’s strategic diversification away from China‑dominated rare‑earth processing.

Key Takeaways

• 97% TREO purity achieved in third MREO test at Jupiter.
• Magnet rare earth recoveries hit ~76% for Nd, Pr, Dy, Tb.
• Jupiter resource holds 1.8 bn tonnes at 1700 ppm TREO.
• High‑purity product strengthens Australia’s alternative rare‑earth supply chain.

Pulse Analysis

The global rare‑earth market is increasingly strained as China controls more than 80% of downstream processing, prompting governments and manufacturers to seek secure, Western‑based sources for the critical metals that power electric vehicles, wind turbines, AI hardware and defence systems. Australia, with its vast clay‑hosted deposits, is positioned to become a key alternative, and the Jupiter project in Western Australia represents the continent’s largest such resource, estimated at 1.8 billion tonnes and roughly 1700 ppm total rare‑earth oxide (TREO). This domestic source could also lower logistics costs and carbon footprints for end‑users.

Critica’s latest metallurgical test delivered a mixed rare‑earth oxide (MREO) product with about 97% TREO purity, a marked improvement over the 84‑86% achieved in earlier trials. The upgraded hydrometallurgical flowsheet also pushed magnet‑rare‑earth recoveries to roughly 76% for neodymium, praseodymium, dysprosium and terbium, while overall rare‑earth recovery hovered around 71%. These figures not only demonstrate technical feasibility but also enhance the economic case for Jupiter, feeding directly into a scoping study with engineering firm Sedgman that will model integrated mining, processing and cost scenarios. The data also suggest scalability potential for larger‑scale production runs.

From an investment perspective, the ability to produce a high‑purity, magnet‑grade rare‑earth concentrate reduces reliance on costly imports and opens pathways for downstream value‑addition within Australia. If the scoping study confirms favorable economics, Jupiter could attract downstream partners seeking to fabricate permanent magnets for renewable‑energy turbines and defence‑grade motor systems, further diversifying the supply chain. Continued optimisation of the final processing stages promises additional recovery gains, positioning Critica to capitalize on the growing demand for clean‑technology metals while mitigating geopolitical risk. Such domestic capability aligns with recent Australian policy incentives for critical minerals.
