Syama, Mali
Overview
Syama, Mali
Syama is located in the southwest of Mali, approximately 30km from the Côte d’Ivoire border and 300km southeast of the capital Bamako.
Syama Gold Mine is a large-scale operation, comprising the established Syama Underground Mine, the Tabakoroni Complex, Syama North and several satellite oxide pits. Syama is owned by local subsidiary Société des Mines de Syama S.A. (SOMISY) in which Resolute has an 80% interest and the Government of Mali holds the remaining 20%. The Tabakoroni complex is owned by Société des Mines de Finkolo S.A. (SOMIFI), part of the Resolute Group.
Syama’s underground mine is a modern sub-level cave producing approximately 2.5 Mtpa of sulphide material. Underground production and development are owner operated. The Syama North (A21) open pit is the other main source of sulphide material.
The sulphide circuit includes three-stage crushing and grinding, followed by flotation to produce autothermal concentrate. Concentrate is thickened to ~70% solids and fed to an autothermal circulating fluidised-bed roaster (~720°C); calcine is treated through conventional CIL, elution, electrowinning and smelting to produce bullion.
The oxide plant treats approximately 1.6Mtpa of oxide and transitional ore. It comprises single-stage jaw crushing and a variable-speed SAG mill, with gravity concentration and an intensive leach reactor for coarse gold, followed by conventional CIL, elution, electrowinning and smelting to produce bullion.
The Syama Sulphide Conversion Project (SSCP) will lift sulphide capacity by 60%, from 2.4Mtpa to 4.0Mtpa, by modifying the oxide comminution circuit and upgrading the roaster. It supports Syama’s long-term outlook as oxide resources deplete, while retaining flexibility to switch back to treating oxide ore.
SSCP commissioning will occur in two stages. Stage 1 started in early Q2 2026, aligned with high-grade sulphide ore from Syama North, and will run at 50% until the secondary crushing circuit and ball mill are online. Stage 2 follows in Q3 2026 after these upgrades, enabling full sulphide throughput.
