Niger’s military government has officially announced the nationalization of its Somair uranium venture, transferring full control from French nuclear firm Orano to the Nigerien state.

The move, which seizes Orano’s 63 percent stake, comes amid accusations of unfair practices and expired mining agreements, marking a significant escalation in the contentious relationship since the 2023 coup.

Orano has responded by launching arbitration and legal proceedings, warning the takeover violates existing contracts and may damage the mine’s future operations.
