    Creation of Nimba Mining Company S.A. (100% Guinean bauxite operator)

    Nimba Mining Company, presented as the first 100% national mining company and owned by a national holding for extracting and processing natural resources, was created on 5 August 2025 and operates the Tinguilinta bauxite mine. Within three months it had loaded a first 200,000-tonne bauxite cargo at Kamsar under a 1.5 Mt sales contract; the Government stated it intends to build alumina refineries. Typed incentive because no other type fits a State-owned operator.
