Viridis Pushes Colossus Closer to Construction-A Material Step in the Rare Earth Race

Highlights

• Viridis Mining submits an Installation Licence application for Brazil's Colossus Project, advancing toward the construction phase and an H2 2026 Final Investment Decision.
• Colossus targets strategic magnet rare earths (dysprosium, terbium) from the world's largest undeveloped ionic clay deposit outside China, with 493M tonnes at 2,508 ppm TREO.
• Beyond mining, Viridis pursues downstream integration through its Viridion joint venture, aiming to build rare earth separation, refining, and recycling capacity outside China's control.

Rare earth projects do not become strategic supply chain assets overnight. Between discovery and commercial production sits a long and difficult industrial journey: exploration, resource definition, environmental licensing, financing, engineering, mine construction, processing, separation, metallization, alloying, magnet manufacturing, and ultimately customer qualification. Most projects never complete the full chain.

That is why the latest milestone from Viridis Mining and Minerals (opens in a new tab) (ASX:VMM) matters. The company was in touch with Rare Earth Exchanges™ with the news.

The company announced submission of its Installation License (IL) application for the Colossus Rare Earth Project in Brazil, a key permitting step that would allow construction and site development activities to begin if approved. The filing follows approval of the Preliminary License in late 2025 and advances the project deeper into the execution phase ahead of a targeted Final Investment Decision (FID) in the second half of 2026.

Importantly, Colossus is not merely another upstream mining story. The project targets magnet rare earths—including dysprosium and terbium—which are critical for high-performance permanent magnets used in EVs, robotics, drones, wind turbines, and defense systems. These heavy rare earths remain among the most strategically constrained parts of the global supply chain.

Viridis also appears to be progressing several parallel de-risking pathways simultaneously: environmental permitting, Engineering, Procurement, and Construction Management (EPCM) contractor selection, demonstration-scale mixed rare earth carbonate production, financing discussions, and offtake negotiations.

The broader industrial reality remains sobering. Mining ore is only the beginning. Separation, refining, metallization, alloying, and magnet production remain dominated by China. But milestones like this demonstrate incremental progress toward building alternative rare earth ecosystems outside Beijing’s orbit.

For Western governments and investors seeking diversified supply chains, Colossus is increasingly a project worth watching.

Profile

Viridis Mining and Minerals is an Australian rare earth development company advancing the Colossus Ionic Clay Project in Brazil’s Poços de Caldas alkaline complex, one of the world’s most prospective emerging ionic adsorption clay (IAC) rare earth districts. The company claims Colossus represents the world’s largest undeveloped ionic clay rare earth deposit outside China, with a global resource of 493 million tonnes grading 2,508 ppm TREO and 601 ppm magnet rare earth oxides (MREO), particularly neodymium, praseodymium, dysprosium, and terbium—materials critical for EVs, robotics, wind turbines, drones, and defense systems. Viridis emphasizes low-cost ionic clay metallurgy, high recoveries, low impurities, and environmentally simpler processing compared to many hard-rock rare-earth projects. The company projects first production by 2028, supported by a staged permitting pathway, demonstration processing plant, and financing support from Brazilian development institutions and export credit agencies.

What makes Viridis particularly notable in the Western rare-earth landscape is that it is moving beyond mining into downstream processing and recycling. Through its Viridion joint venture with Ionic Rare Earths, the company aims to develop rare-earth separation, refining, and recycling capacity in Brazil, positioning itself as a potential non-Chinese participant in an integrated supply chain.

While the company still faces major execution risks common to all rare earth ventures—including financing, permitting, construction, separation capability, and customer qualification—it has advanced meaningfully along the industrial pathway with preliminary environmental approval, demonstration-scale MREC production, and active EPCM, financing, and offtake discussions already underway.
