Guinea and UAE's Emirates Global Aluminium settle bauxite dispute, restoring supply to Abu Dhabi refinery

Summary

The Republic of Guinea, Emirates Global Aluminium (EGA) and its subsidiary Guinea Alumina Corporation (GAC) announced a definitive settlement on May 6, 2026 that resolved all disputes stemming from the suspension of GAC's activities and the interruption of Guinean bauxite supplies to EGA's Al Taweelah alumina refinery in Abu Dhabi. Guinea's state-invested vehicle Compagnie des Bauxites de Guinée (CBG, 49% state-owned) had suspended bauxite supply in a dispute over concession terms. The settlement transfers the Sangarédi bauxite project assets to Nimba Mining Company (NMC), a Guinean entity, in exchange for a lump-sum payment to GAC; NMC then assumes bauxite supply obligations to EGA under revised commercial terms. The agreement also renews the CBG-EGA bauxite supply agreement under new commercial terms described as mutually beneficial. Guinea holds the world's largest bauxite reserves, and Al Taweelah is one of the largest single-site alumina refineries in the Middle East.

The split

EGA and the UAE frame the settlement as a commercial resolution that restores supply-chain certainty and protects a strategically important alumina refinery. Guinean legal commentary (Afronomicslaw) emphasises the transfer of Sangarédi project control to a Guinean-controlled entity as a meaningful nationalisation outcome, consistent with the Mamadi Doumbouya government's policy of increasing state participation in mining projects inherited from the Condé era. African mining trade media reads the dispute as part of a broader pattern of Guinea reasserting terms on existing concessions signed under prior administrations, similar to moves in iron ore (Simandou) and bauxite (CBG). The settlement's "revised commercial terms" are not fully public, so the actual balance of value capture between EGA and the Guinean state is unclear.

By the numbers

• May 6, 2026, date of definitive settlement between Guinea, GAC and EGA.
• 49%, Guinea's equity stake in CBG (the state's share of the bauxite supply partnership).
• Al Taweelah, EGA's Abu Dhabi alumina refinery, one of the Middle East's largest.
• Sangarédi, the Guinean bauxite project transferred to NMC under the settlement.
• Guinea, world's largest holder of bauxite reserves.

Why it matters

Guinea supplies roughly 25% of global bauxite, the ore that produces Aluminium via alumina refining. CBG alone is among the world's largest bauxite producers. A sustained supply interruption to Al Taweelah would have rippled through UAE aluminium production and the global primary aluminium balance. The settlement validates a Guinean negotiating approach of suspending supply until terms improve, a playbook that has precedent in Guinea's broader renegotiation of mining concessions under the Doumbouya military government. For global bauxite supply chains, Guinea remains a systemic concentration risk: political instability, coup risk (the 2021 coup that removed Condé) and active renegotiation of legacy contracts create recurring supply uncertainty that no bauxite buyer dependent on Guinean supply can fully hedge.

What to watch

• The actual commercial terms of the renewed CBG-EGA supply agreement: revenue-sharing ratio and royalty structure.
• NMC's capacity to develop the Sangarédi bauxite project and whether it attracts non-EGA financing.
• Guinea's broader mining-concession renegotiation posture: Simandou iron ore, Simon mining, and other legacy agreements.
• Guinea's political stability under the Doumbouya transitional military administration.
