The Mokanji Bauxite Mine, located in the Moyamba District, is the primary center for aluminum ore production in Sierra Leone. Development of the site began in the 1960s, and it is currently operated by Sierra Mineral Holdings Limited, a subsidiary of the Vimetco Group. The operation utilizes open-cast mining techniques, which are highly efficient due to the bauxite's proximity to the surface. Processed ore is transported to the Port of Nitti for international shipment, feeding global aluminum supply chains. Over several decades, the mine has been instrumental in developing regional infrastructure, including vital road networks and local power distribution. Despite fluctuations in global commodity prices, Mokanji remains a steadfast contributor to the nation's mineral exports. Current efforts by the operator focus on upgrading loading facilities and enhancing environmental protocols for pit rehabilitation.
