Production challenges and logistical hurdles
The national manganese output dropped to 9.1 million tonnes last year, spotlighting critical deficiencies in the country’s logistics network. Frequent breakdowns and bottlenecks along the Transgabonais railway, which connects key mining zones to the Owendo port, have repeatedly disrupted operations. Yet, the fourth quarter of 2025 marked a clear rebound in production.
This recovery stems from the reactivation of mining sites in Moanda and Franceville, where output surged by 10.8% compared to the previous quarter, according to official economic and fiscal policy reports. Beyond extraction, the industry is gradually shifting toward local processing—a move aimed at adding value to raw materials.
Strategic partnership drives transformation goals
In mid-2026, the Gabonese government and Eramet, a French industrial group, formalized a landmark agreement in Paris. Under this deal, Eramet committed to processing up to 700,000 tonnes of manganese annually within Gabon by the end of 2031. Three potential pathways are under consideration: upgrading the metallurgical complex in Moanda, establishing processing units near Owendo, or constructing a manganese oxide plant for battery production close to Libreville.
Addressing public skepticism, the Ministry of Industry clarified that Eramet’s pledge represents only part of the broader transformation effort. Other operators will also be required to contribute to the initiative, ensuring a collective push toward value addition.
Industry prepares for raw ore export ban
The push for local processing aligns with Gabon’s ambitious 2029 deadline, when raw manganese ore exports will be prohibited. To meet this target, Eramet is investing in sustainable energy solutions and integrating biocharbon into its operations, reinforcing its commitment to an eco-friendly industrial transition.
