Critica’s Jupiter Project Hits 97% TREO with Enhanced Rare Earth Recoveries

Critica Limited has achieved a major leap in rare earth product quality at its Jupiter Project, producing a Mixed Rare Earth Oxide with approximately 97% Total Rare Earth Oxide and strong recovery rates that bolster its mine-to-magnet ambitions.

  • Third MREO reaches ~97% TREO
  • Total rare earth recovery up to ~71%
  • Magnet rare earth recovery up to ~76%
  • Ongoing metallurgical optimisation underway
  • Scoping Study progressing with Sedgman

Breakthrough in Rare Earth Concentrate Purity

Critica Limited (ASX:CRI) has pushed the envelope at its Jupiter Rare Earth Project in Western Australia by producing a third Mixed Rare Earth Oxide (MREO) sample boasting an impressive 97% Total Rare Earth Oxide (TREO). This marks a substantial improvement on previous batches graded at 84% and 86% TREO, underscoring the company’s advancing hydrometallurgical processing capabilities.

The enhanced purity not only elevates the product’s value but also signals progress towards a commercially viable, high-quality concentrate that could compete with the dominant Chinese rare earth refining sector. The latest testwork also reported total rare earth recoveries reaching approximately 71%, with magnet rare earth elements (Nd, Pr, Dy, Tb) recovering up to 76%, metrics that CEO Jacob Deysel flagged as supportive of robust project economics.

Refining the Flowsheet and Project Economics

These metallurgical gains form a critical input into the ongoing Scoping Study led by Sedgman, which aims to define the Jupiter Project’s development pathway. Critica’s optimisation efforts build on earlier beneficiation improvements that lifted magnet rare earth recovery to around 81%, as reported in April 2026, and continue to refine assumptions around recovery and product quality.

Critica’s approach involves a mine-to-magnet strategy, integrating beneficiation and downstream processing to deliver a product aligned with the needs of electric vehicles, renewable energy, AI infrastructure, and defence sectors. The company is also engaging multiple specialist laboratories including ANSTO and Phenikaa University to advance REE extraction and product qualification.

Strategic Positioning Amid Global Supply Chain Shifts

The Jupiter Project’s progress towards producing a high-purity MREO positions Critica as a potential alternative rare earth supplier outside China’s dominant refining landscape. With rare earth demand accelerating globally, particularly for magnet rare earths critical in clean technologies and defence applications, the ability to deliver a concentrate with ~97% TREO and strong recoveries is a notable milestone.

These developments come as Critica simultaneously advances other projects, such as the Mt Lindsay tin-tungsten asset, where an ESG-focused underground mining Scoping Study is underway, reflecting a broader strategic pivot within the company’s portfolio.

Next Steps and Ongoing Challenges

While the metallurgical results are promising, Critica continues to work on optimising the final stages of its hydrometallurgical flowsheet to unlock further recovery upside. The company’s next key milestones include the completion of the Sedgman-led Scoping Study and advancing pilot plant operations that will test scale-up potential and product consistency.

Investors will be watching how these technical advances translate into economic feasibility and commercial partnerships, especially given the competitive and geopolitically sensitive nature of rare earth supply chains. The interplay between improving product quality, recovery rates, and cost management will be critical as Critica seeks to carve out a niche in a market dominated by entrenched players.

Bottom Line?

Critica’s leap to a 97% TREO concentrate strengthens Jupiter’s development case but hinges on translating lab success into scalable economics amid intense supply chain competition.

Questions in the middle?

  • Can Critica sustain or improve recovery rates during scale-up and commercial operations?
  • How will the final Scoping Study shape investment and development timelines for Jupiter?
  • What strategic partnerships might emerge to support Critica’s mine-to-magnet ambitions?
