Colossus

Colossus is a rare-earths mining project located in Brazil. The facility is being developed to extract and process critical minerals, with a focus on rare-earth elements that are essential for modern technologies including electric vehicles, renewable energy systems and advanced electronics. The project is owned and operated by Viridis Mining and Minerals, a company backed by investors including ORE Investments and Régia Capital. Colossus has attracted significant international financial support, securing backing from export credit agencies and development finance institutions across multiple countries. Export Finance Australia, Export Development Canada, Bpifrance Assurance Export and the Brazilian National Bank for Economic and Social Development have all provided financing or guarantees for the project. The involvement of these institutions reflects the strategic importance of rare-earths supply chains to resource-importing nations seeking to diversify away from dominant suppliers. Brazil's rare-earths sector has gained attention as countries and companies work to secure alternative sources of critical minerals. The Colossus project represents a significant investment in Brazil's mining infrastructure and positions the country as an emerging player in the global rare-earths market. Rafael Moreno has been associated with the project's development and financing activities.
