Critica Limited is progressing its Jupiter and Mt Lindsay projects with key resource updates, metallurgical breakthroughs, and strategic partnerships, targeting Scoping Study completion in Q3 2026.
- Jupiter delivers up to 14x concentrate upgrade and 81% magnet rare earth recovery
- Commercial-grade rare earth products produced at Jupiter
- Mt Lindsay pivots to low-impact underground mining approach
- Secured $300,000 non-dilutive funding and joined U.S. Defense Industrial Base Consortium
- Both projects on track for Scoping Study completion in Q3 2026
Jupiter Project Breaks New Ground in Rare Earth Processing
Critica Limited (ASX:CRI) is rapidly advancing its Jupiter Rare Earth Project in Western Australia, showcasing significant metallurgical progress that could reshape its economics. The project has achieved a beneficiation upgrade factor of up to 14 times, concentrating rare earth oxides (REO) with approximately 81% recovery of magnet rare earth oxides (MagREO) and 71% total rare earth oxide (TREO) recovery. These results underpin a beneficiation-first development strategy that promises to reduce downstream processing volumes and costs.
Complementing this, Critica has produced commercial-grade rare earth products, including a ~58% TREO Mixed Rare Earth Carbonate (MREC) validated by ANSTO and a ~97% TREO Mixed Rare Earth Oxide (MREO) independently confirmed by Australian Mineral and Metallurgical Laboratories. These milestones mark a critical step from technical validation towards commercial engagement, with product qualification samples now being prepared to support offtake discussions.
Resource Optimisation and District Growth Potential
Over the past year, Critica completed 145 infill drill holes totaling 7,265 metres at Jupiter, targeting higher-grade zones to refine selective mining strategies. This extensive drilling campaign feeds into an updated Mineral Resource Estimate being prepared by SRK Consulting, expected to enhance mine planning and feed into the Scoping Study due in Q3 2026.
Beyond Jupiter itself, regional drilling at the Juno and Aurora prospects within the Brothers Project signals broader district-scale growth potential. Results from a WA Government co-funded drilling program at Juno are imminent, potentially expanding the resource footprint.
Mt Lindsay Shifts to Environmentally Focused Underground Mining
In Tasmania, the Mt Lindsay Tin-Tungsten Project is undergoing a strategic reassessment, pivoting from previous open-pit concepts to a low environmental footprint underground mining approach. This shift aims to improve ore selectivity, reduce surface disturbance, and boost project economics amid tightening global supply constraints for tin and tungsten.
Mt Lindsay holds approximately 81,000 tonnes of tin and 32,000 tonnes of tungsten, positioning it as one of the world’s largest undeveloped tin-tungsten deposits. The project benefits from an existing Mining Lease and proximity to the Port of Burnie, easing export logistics. DRA Global is leading the Scoping Study, with updated geological modelling and resource optimisation underway, targeting completion alongside Jupiter’s study in Q3 2026.
Strategic Partnerships and Funding Boost Development
Critica has bolstered its development momentum by securing $300,000 in non-dilutive funding from the WA Government’s MRIWA and RTCM Trailblazer programme to accelerate metallurgical work at Jupiter. The company also joined the U.S. Defense Industrial Base Consortium (DIBC), enhancing its access to strategic partnerships and supply chain initiatives amid Western governments’ push to diversify critical minerals sourcing away from China.
These moves align Critica’s portfolio with growing government support and stockpiling efforts across rare earths, gallium, tin, and tungsten in key markets including the U.S., Australia, and Europe.
Upcoming Catalysts Poised to Unlock Value
With multiple workstreams converging, Critica is entering a critical phase of catalyst delivery. Key upcoming milestones include the release of updated Mineral Resource Estimates for both projects, further metallurgical optimisation results at Jupiter, progression of gallium and co-product evaluations, and the finalisation of Scoping Studies for Jupiter and Mt Lindsay during Q3 2026.
Offtake discussions are advancing in parallel, supported by ongoing product qualification activities. The company’s upcoming investor webinar on 22 June 2026 promises further insights into these developments.
Bottom Line?
Critica’s dual-project strategy is gaining technical and strategic traction, but the market will be watching closely for the Scoping Study outcomes that will crystallise the projects’ commercial viability.
Questions in the middle?
- How will the updated Mineral Resource Estimates impact project economics and mine planning?
- What are the potential market pathways and pricing dynamics for Jupiter’s gallium co-product?
- To what extent can Mt Lindsay’s underground mining approach improve environmental and economic outcomes compared to prior open-pit plans?
