Critica Limited (ASX: CRI) Unveils Maiden Mineral Resource for Jupiter Project
Global Mineral Resource
Critica Limited has released an independent maiden Mineral Resource Estimate for its Jupiter Project, part of the wholly-owned Brothers Clay-Hosted Rare Earth Project in Western Australia. The Inferred MRE totals 1.8 billion tonnes at 1,700 ppm TREO with a 1,000 ppm cut-off and 500 million tonnes at 2,200 ppm TREO with a 1,800 ppm cut-off, surpassing the company’s initial expectations.
Key Highlights
The Jupiter Project is now recognized as Australia’s largest and highest-grade clay-hosted rare earth resource. Key features include a broad, shallow deposit spanning 42 square kilometres with consistent high-grade mineralisation. Over 50% of drill holes intersected mineralisation with an average depth of just 58 metres. The resource boasts a high-value MREO content averaging 23% of TREO and maintains very low levels of uranium and thorium. Additionally, the project’s strategic location benefits from established mining infrastructure, enhancing its development potential.
Metallurgical Testwork
Initial metallurgical testwork has demonstrated a significant beneficiation upgrade of 830% alongside a 95% reduction in mass. These results highlight the potential for efficient processing of the high-grade clay-hosted rare earth elements, reinforcing the project’s economic viability.
Executive Comments
Managing Director, Philippa Leggat, stated, “It is incredibly exciting to be able to unveil Australia’s premier clay hosted rare earth deposit—the numbers speak for themselves. Our maiden resource represents a major milestone that we have, rather remarkably, delivered in just over a year from announcing the discovery in November 2023. The size and grade in the clay-hosted Jupiter deposit is unmatched in Australia, and globally significant. The development potential is boosted by its exceptional location in a well-established, West Australian mining district that benefits from robust existing infrastructure. Moreover, the near-surface and highly consistent nature of the deposit affords us optionality when it comes to considering future processing and development scenarios.”
