SMB’s activities are geographically concentrated in western Guinea, in the Boké region. Extraction takes place on SMB’s three mining sites: Santou and Houda, Malapouya, and Dabiss plateaus. After the mining operations, the bauxite is transported to the river ports of Katougouma and Dapilon, from where the crushed ore is transported to the open sea on barges. The bauxite is then transhipped by floating cranes onto cargo ships that export the bauxite to its destination.
