Iron Ore
Simandou introduces a new high-grade supply source into the seaborne market, with rail and port capacity as the critical path.
Bauxite
Guinea is the world's largest bauxite exporter; the strategic question is how much value is captured through domestic alumina refining.
Related countries
Guinea
Guinea is the world's leading bauxite exporter and host of Simandou, one of the largest untapped high-grade iron ore deposits, developed together with a trans-Guinean railway and a new port.
South Africa
South Africa has the continent's deepest mining, metals and chemicals industrial base, and its energy agenda is dominated by Eskom's generation fleet, transmission capacity and the renewables procurement programme.
