Bassin de Tim Mersoï; Tim Mersoi Basin


Fluvio-deltaic sedimentary packages that host significant uranium mineralisation. Main deposits: Marianne, Marilyn, Maryvonne, MSNE and Miriam.

The sedimentary Tim Mersoï Basin covers an area of some 114,000 km2. The basin is itself part of the larger Lullemeden Basin (of Palaeozoic-Teriary age) that extends into Mali, Algeria, Benin and Nigeria.

All known uranium deposits in Niger are located within the Tim Mersoï Basin including those at Arlit, Imouraren and Agadez.
Hosts the highest-grade and tonnage uranium ores in Africa, totaling 439 400 t U. west of the Aïr Mountains.
