Manganese production in Gabon has dropped to 9.1 million tonnes, drawing attention to critical gaps in the nation’s logistics infrastructure. Frequent breakdowns and bottlenecks along the rail network—particularly the Transgabonais line leading to Owendo Port—have disrupted supply chains. Yet, the fourth quarter of 2025 marked a clear rebound in output.

This recovery stems from the revitalization of key mining sites in Moanda and Franceville, where production surged by 10.8% compared to the previous quarter, according to the Directorate-General for Economy and Fiscal Policy (DEPF). While extraction remains vital, the industry is increasingly focusing on adding value through local processing.

Government and Eramet forge manganese transformation deal

In July 2026, the Gabonese government and French mining giant Eramet signed a landmark agreement in Paris. Under this deal, Eramet pledges to process up to 700,000 tonnes of manganese ore annually within Gabon by the end of 2031. Three potential pathways are under consideration: upgrading the Moanda metallurgical complex, establishing new processing units at Owendo, or building a manganese oxide battery plant near Libreville.

The Ministry of Industry has clarified that these 700,000 tonnes represent Eramet’s commitment alone. Other mining operators are expected to contribute to the broader goal of onshore manganese transformation.

Eramet is also advancing plans to secure stable energy supplies and integrate biocharcoal into its operations, signaling a strategic move toward compliance with the 2029 ban on raw ore exports.
