SnapshotThe Moanda mine is one of the world’s richest manganese deposits, with commercial ore grading around 45%.

In 2024, Eramet was the world’s leading producer of high-grade manganese ore, holding a 26% market share.

In September 2024, due to market oversupply, the company temporarily suspended mining operations for three weeks, although sales and shipments continued, helping to stabilize the market.

In June 2025, the Gabonese government announced a ban on unprocessed manganese ore exports starting January 1, 2029, to promote local processing. Eramet expressed its readiness to work with the authorities and support continued operations through Comilog and Setrag.

Summary:

Moanda is mining high-grade manganese tabular deposits, located under low overburden layer and formed by the weathering of volcano-sedimentary rocks. Manganese ore is found in 5 plateaus around Moanda. They are Bangombe, Okouma, Bafoula, Massengo and Yeye, the most important being Okouma and Bangombe. The manganese ore in the mine is a result of Supergene Sulphide enrichment of the Precambrian Francevillian sediments.
