Jupiter's beneficiation strategy aims to enhance processing efficiency by rejecting approximately 95% of mined material early, thus creating higher-grade concentrate streams and reducing environmental impact.

The Jupiter project, part of the broader Brothers project, spans 1500 square kilometers in a prime mining district near Mt Magnet, Western Australia, with strategic access to infrastructure including the Mount Magnet-Geraldton highway leading to the Port of Geraldton, 250 kilometers away.

Critica Limited has confirmed a high-grade zone within the Jupiter project, totaling 640 million tonnes at a grade of 490 parts per million (ppm) of magnet rare earth oxides, marking it as Australia's highest-grade clay-hosted rare earths resource.

Overall, the Jupiter resource totals 1.8 billion tonnes, with an average of 1700 ppm total rare earth oxides (TREO), calculated using a 400 ppm MREO cut-off.

The high-grade endowment includes approximately 310,000 tonnes of in-situ magnet rare earth oxides, featuring essential elements such as 66,000 tonnes of praseodymium, 230,000 tonnes of neodymium, and significant amounts of terbium and dysprosium, which are critical for high-performance permanent magnets.

These magnet rare earths are vital for manufacturing components in electric vehicles, wind turbines, medical devices, and defense systems, representing up to 85% of a project's value despite being a small fraction of the total mineral content.

A scoping study is underway to evaluate the project's high-value MREO zones, while Critica is actively engaging with offtake partners to ensure environmentally and socially responsible supply chains.

Critica's innovative development approach focuses on economic viability and environmental responsibility, utilizing targeted analysis of MREO-specific cut-off grades to optimize the project's economic potential.

The project adopts a strategic patience approach, prioritizing thorough resource characterization and long-term value creation over rushing to production.

Critica is advancing its metallurgical test work to produce a mixed rare earth carbonate (MREC), aiming for up to 95% mass reduction while enhancing concentrate grades to about 15,000 ppm TREO.

The deposit hosts fine-grained rare earth minerals such as florencite, rhabdophane, and xenotime, which are environmentally favorable due to their low levels of uranium and thorium.

Extensive drilling since the project's discovery in late 2023 has totaled over 37,000 meters, revealing significant mineralized zones with standout intercepts, including 74 meters at 1907 ppm and 16 meters at 4129 ppm TREO.
