Rainbow Rare Earths (OTCMKTS:RBWRF) is a mineral exploration and development company focused on rare earth element deposits in East Africa. Headquartered in London, the company is engaged in the acquisition, exploration, development and mining of rare earth projects that serve global technology and manufacturing markets. By targeting light and heavy rare earth elements—critical inputs in electric vehicles, wind turbines, and other high-growth sectors—Rainbow aims to become a stable, long-term supplier of strategically important minerals.
The company’s flagship asset is the Gakara Rare Earth Project in southwestern Burundi, which hosts one of the world’s highest-grade rare earth deposits. Rainbow holds a majority interest in the project, with the remainder owned by the Government of Burundi and local partners. Following an updated resource estimate and feasibility studies, the operation commenced bulk ore sorting in 2019 and began shipping a mixed rare earth concentrate to separation facilities in Asia. Gakara’s high grades and proximity to infrastructure have positioned it as a cost-effective source of neodymium, praseodymium, dysprosium and terbium.
In addition to Gakara, Rainbow Rare Earths maintains a portfolio of early-stage exploration licenses in southern Africa, including prospective projects in South Africa and Tanzania. These complementary assets are being advanced through regional sampling programs and metallurgical test work, with the goal of expanding the company’s resource base and diversifying its geographic footprint.
Under the leadership of an experienced mining and technical management team, Rainbow Rare Earths emphasizes sustainable development and community engagement. The company works closely with local stakeholders to foster socio-economic benefits, environmental stewardship and transparent governance. With rare earth demand forecast to grow alongside the energy transition, Rainbow is positioned to support downstream manufacturing and strategic metal supply chains.
