The French state’s decision to increase its Eramet stake places the mining group at the center of a debate extending beyond Paris. Through Compagnie minière de l’Ogooué (Comilog), the group operates Gabon’s Moanda manganese deposit, among the world’s largest. For workers and observers in Libreville, the question is what a group-level ownership change means for the Gabonese company, its operations and local benefits.
On October 12, the French government announced participation in a €500 million Eramet capital increase planned before the end of 2026. Following the transaction, the state is expected to become the group’s largest shareholder. The mechanism combines subscription proportionate to its current stake with acquisition of preferential rights held by longstanding partner Sorame-CEIR. Completion remains subject to regulatory approvals, including an exemption from the Financial Markets Authority.
A transaction decided at group level
France presents its increased involvement as an industrial sovereignty and critical metal supply-security measure. The capital increase is also intended to strengthen Eramet’s balance sheet and finance its extraction and initial mineral-processing strategy. Precise governance arrangements and final shareholdings remain to be specified after completion and a new shareholder agreement.
The proposed public stake concerns the listed parent company, which owns subsidiaries in several countries. It does not mean France directly acquires the Moanda mine or replaces Gabonese institutions in subsurface management. Comilog operates under Gabonese law and remains subject to Gabon’s permits, tax obligations, labor rules and environmental standards.
This distinction between parent company and local operator matters, but does not rule out possible effects. The largest shareholder can influence strategy, investment, portfolio priorities and group financing choices. If new governance strengthens particular assets, reallocates capital or establishes partnerships, subsidiaries may be affected. At this stage, no specific Comilog operational change has been announced as part of the fundraising.
A social and national perspective in Libreville
In its reporting, RFI gathered reactions from a representative of workers in Gabon’s mining and metallurgical industries. He believes an increased French stake in Eramet does not itself alter Comilog’s legal status or Gabonese territorial sovereignty. His view highlights a recurring concern: ownership of an international group and legal control of mining activity are separate levels.
Employees also care about practical effects on jobs, working conditions, investment and relations with the Gabonese state. A shareholder change guarantees neither expanded capacity nor reduced spending. Decisions affecting Moanda’s industrial plan, production, equipment, training and labor dialogue will matter.
For Gabon, manganese is a strategic asset and major export revenue source. The national priority is ensuring extraction generates revenue, skilled jobs, local purchasing and processing capacity. The country has also sought stronger domestic mineral beneficiation, making Comilog’s investment decisions economically important beyond mining output alone.
Governance issues to monitor
The French state justifies its intervention through critical metal supply security. This responds to international competition in which governments seek to protect materials needed for batteries, the energy transition and industrial technologies. Gabon, meanwhile, must ensure group ownership changes do not weaken its negotiating power over project obligations and expected economic benefits.
Transparency will be decisive. Publishing final capital-increase terms, the shareholder agreement and industrial directions would clarify evolving governance. Locally, monitoring investment, payments, production and social commitments would distinguish recapitalization effects from other factors influencing the mine.
The French state’s growing Eramet stake therefore does not transfer Moanda to Paris, but changes the balance within the parent controlling Comilog. For Gabonese workers and authorities, the answer will lie in industrial decisions and enforcement of the national framework. Fundraising must be assessed both as a financial rescue and a strategic choice whose effects on the main Gabonese asset remain to be observed.
