An agreement signed on May 6 ends the legal standoff between Guinea and Emirates Global Aluminium. NMC inherits the assets. CBG supply contracts are renewed.
A joint statement published on May 6, 2026 ended months of tension between the Republic of Guinea and Emirates Global Aluminium (EGA), the Emirati mining group controlling Guinea Alumina Corporation (GAC). The deal was signed in the presence of the President of the Paris Bar Association, who led the mediation. Guinea’s delegation was headed by Minister of Mines Bouna Sylla and Minister of Economy Mariama Ciré Sylla.
The published terms are unambiguous. Conakry makes a lump-sum payment to GAC as compensation. The operational assets of the Boké site are transferred to Nimba Mining Company (NMC), the state-owned entity created by presidential decree in August 2025. The bauxite supply agreements linking GAC to Compagnie des Bauxites de Guinée (CBG) are renewed, allowing EGA to continue sourcing from the world’s largest exporter.
The dispute traced back to GAC’s failure to build an alumina refinery within the agreed deadlines. The original deadline had already been extended to September 2026. The Guinean government suspended GAC’s exports in October 2024, then transferred the concession to NMC. EGA subsequently initiated legal proceedings against Conakry.
Why does this deal matter? First, because it demonstrates that Conakry’s strategy worked within the boundaries of international law. Guinea recovers the assets, installs its state operator, and receives a payment. At the same time, it avoids the costs of a long and uncertain international arbitration before the ICSID. This double clean exit was far from guaranteed six months ago.
The second issue is supply continuity. EGA is one of the most structurally important buyers in the Guinean bauxite chain. Its UAE refineries, like its partners in Asia, depend on the specific grades of Guinean bauxite. A prolonged halt in deliveries would have weighed on processing margins across the entire downstream value chain. The renewal of CBG-EGA contracts addresses this continuity requirement.
The reference in the joint statement to the “Simandou Strategic Committee” is not incidental. It signals that the resolution of the GAC dispute fits into a broader governance architecture aimed at consolidating state control over the entire Guinean mining sector, covering both bauxite and iron ore.
What changes is NMC’s status in Guinea’s mining landscape. The company, created barely nine months ago, absorbs a productive asset and inherits an established commercial relationship with a global-calibre buyer. Its trajectory is no longer that of a simple industrial policy vehicle. It is becoming an operator with real assets, contractual obligations and a supply base to manage.
What is also revealed is Conakry’s capacity to conduct this type of negotiation with a group the size of EGA. The presence of the President of the Paris Bar Association as mediator signals a professional, documented, and legally defensible process. This is not a summary nationalisation. It is a bilateral agreement with an explicit compensation mechanism.
What is being prepared, finally, is an operational management test for NMC. Absorbing GAC’s assets, maintaining exports, honouring CBG-EGA contracts, and simultaneously advancing feasibility studies for the future alumina refinery: this is a demanding timeline for an entity less than a year old.
The question now opening is whether NMC can function as a credible long-term operator. Guinea has demonstrated its ability to reclaim assets. It must now demonstrate its ability to operate them. The first production figures under the NMC banner will be the key indicators to watch in the coming quarters.
