What Comilog does

Comilog is a wholly-owned subsidiary of Eramet, the French publicly listed mining and metals group, and constitutes Eramet's manganese franchise. The company extracts and processes high-grade manganese ore at the Moanda open-pit mine in Gabon — described as one of the world's largest manganese deposits — and produces manganese alloys at the Comilog Dunkerque facility in northern France. Its core technology is large-scale open-pit mining integrated with metallurgical processing, supported by Eramet's owned rail logistics subsidiary Setrag in Gabon.

Comilog's products — manganese ore, sintered ore, and manganese alloys — are sold B2B under negotiated long-term contracts to industrial customers, primarily global steel manufacturers that use manganese as an alloying element for strengthening and desulfurization. Pricing is not publicly disclosed and follows global manganese market indices. Distribution is handled through Eramet's logistics infrastructure, with products reaching customers across Europe, Africa, North America, South America, Asia-Pacific, and Oceania.

The business is positioned around sustainability: Comilog markets responsibly-sourced manganese to support customer decarbonization in steelmaking, participates in biodiversity programs under Eramet's Environment Week, and benefits from the EU Just Transition Fund at Comilog Dunkerque for workforce retraining. Strategic priorities signaled in 2026 include a structured MOU with the Gabonese Republic to transform the local manganese value chain, reinforcing long-term resource and political continuity for the flagship operation.

Broad incumbents

• Glencore: Glencore is a major diversified miner and commodity trader with material manganese exposure alongside its cobalt, nickel, and zinc businesses. It overlaps with Comilog in manganese trading and downstream supply to steelmakers.
• Eramet: Eramet is the publicly-listed parent company of Comilog and a broader mining group spanning manganese, nickel, mineral sands, and lithium. It is comparable as the parent group benchmark for valuing Comilog's manganese business.
• BHP: BHP is a diversified global miner with historical and current exposure to manganese through its Australian and South African joint ventures, making it a broad incumbent peer in the global manganese value chain.
• Tronox Holdings: Tronox is a major mineral sands (TiO2, zircon) producer, comparable to Eramet's broader portfolio including Comilog's sister mineral sands operations. Both share exposure to industrial mineral markets serving similar downstream industries.

Direct peers

• Vale: Vale operates manganese mining operations in Brazil, including the Azul mine, and is one of the largest global manganese producers. It competes with Comilog in both manganese ore and downstream ferroalloy markets.
• Jupiter Mines: Jupiter Mines owns a significant stake in the Tshipi Borwa manganese mine in South Africa, one of the world's largest single manganese assets. It is a direct peer to Comilog in global manganese ore supply.
• OM Holdings: OM Holdings is a vertically integrated manganese producer with mining operations and smelting/alloy production in Malaysia and South Africa, competing directly with Comilog's mining-to-alloy value chain.
• South32: South32 is one of the world's largest manganese producers through its Australian operations (GEMCO) and South African Mamatwan/Wessels mines. It directly competes with Comilog in global manganese ore and alloy markets serving the steel industry.
• Anglo American: Anglo American operates significant manganese mining assets in South Africa through its joint ventures, directly competing with Comilog as a major global manganese ore supplier to steelmakers.

Emerging players

• Pilbara Minerals: Pilbara Minerals is a major lithium producer that, like Eramet's lithium operations, supplies battery raw materials to the EV/storage market. It is comparable to Eramet's diversification beyond manganese into the battery materials theme.
