GAC’s 2Mt bauxite pile-up in Guinea: What built it, what’s blocking it, and what could break the deadlock

In October 2024, Guinean customs authorities suspended bauxite exports from Guinea Alumina Corporation (GAC), a subsidiary of Emirates Global Aluminium (EGA), due to unresolved issues with the Guinean government, chiefly around concerns over GAC’s failure to progress on its commitment to build a domestic alumina refinery. As a result, GAC halted exports, and by early 2025, around 2 million tonnes of bauxite had accumulated at the port in Kamsar, unable to be shipped.
Located in northwestern Guinea, GAC operates a vast 690-square-kilometre mining concession that feeds directly into international supply chains, thanks to a dedicated rail link to its port at Kamsar.
Since exports began in 2019, GAC has become a key supplier of bauxite, the primary ore for aluminium production, to third-party customers worldwide. In 2024 alone, the company exported 10.8 million tonnes of bauxite, a significant volume contributing to both EGA’s own needs and the global aluminium value chain. A portion of this bauxite also supplies EGA’s Al Taweelah alumina refinery in Abu Dhabi.
