Last amendment: > on 2026-05-06.
On 11 October 2024, Guinean customs authorities suspended bauxite exports from Guinea Alumina Corporation's Boké mine without a public gazette notice; EGA's own public statement said only that it was "seeking clarity from customs on the reason for this action, and are working to resolve this as quickly as possible." Later reporting attributed the suspension to Guinea's push — under President Mamadi Doumbouya's post-2021 mining-code reforms — to compel GAC to build a domestic alumina refinery as required under its base convention, a commitment GAC had not advanced.
Production at EGA's Al Taweelah alumina refinery in the UAE continued as normal in the immediate aftermath, but the export halt caused a ~2 Mt bauxite inventory buildup at the port of Kamsar and cut GAC's annual export volume from 14.1 Mt (2023) to 10.8 Mt (2024). EGA recorded a AED 1.8 billion ($488 million) impairment on GAC's book value at FY2024 year-end as a direct consequence.
The suspension triggered an immediate price reaction: Bloomberg and mining.com reported aluminium and alumina prices jumping on the news, with China domestic alumina benchmarks subsequently setting records through late 2024 as the market priced in a sustained Guinea supply disruption (Guinea accounts for roughly a fifth of global seaborne bauxite exports and GAC alone represents a meaningful share of that).
18-month sequence — suspension (Oct 2024) → concession revocation and transfer to state-owned Nimba Mining Company (Aug 2025) → amicable settlement restoring EGA offtake via CBG/NMC (May 2026). See the amendment log above and the two follow-on actions in this register.
that Guinea would use export controls, not just permit administration, to enforce the Mining Code's refinery-development requirement — a template later applied more forcefully against GAC's full concession and is being used as leverage in Guinea's concurrent SMB/CBG refinery ultimatum.
supply shock moving global alumina/aluminium prices independently of Indonesia's bauxite export ban — do not conflate the two when attributing the Oct/Nov-2024 alumina price spike.
