About Us
Developing Tanzania's uranium, responsibly
Mantra Tanzania Limited is developing the Mkuju River Uranium Project in the Ruvuma Region — bringing the expertise of Uranium One and the ROSATOM group to Tanzania, with safety, the environment and local communities at the centre of everything we do.
A global nuclear leader, rooted in Tanzania
Mantra Tanzania Limited is a subsidiary of Uranium One — part of ROSATOM, the Russian state nuclear corporation and one of the world's leading uranium producers. We are developing the Mkuju River Uranium Project in the Namtumbo District of the Ruvuma Region, in southern Tanzania.
By combining ROSATOM's world-class technology and safety systems with strong local partnership, we develop Tanzania's uranium resources to the highest international standards — protecting the surrounding environment and sharing the benefits of the project with our host communities.
