Sabodala-Massawa mine
Sabodala-Massawa is the largest producing gold mine in Senegal and has been in operation for over a decade. The mine was acquired as part of Endeavour’s acquisition of Teranga in February 2021.
Endeavour has expanded the Sabodala-Massawa mine with the addition of a new BIOX processing facility. The new processing facility adds incremental production of 1.35Moz at a low AISC of $576/oz over its mine life. First gold was poured at the BIOX processing facility on 18 April 2024.

Exploration potential
Within the vast Sabodala-Massawa property, the discovery of between 1.5 and 2.0Moz of mineral resources over the 2026 to 2030 period is targeted, prioritising targets that can support the mine plan.
Current exploration efforts are focused on the Makana and Kawsara targets, which are expected to provide non-refractory resources to support the mine plan, while the Goulouma and Kerekounda underground deposits are expected to provide high grade non-refractory ore in the medium term to bolster the grade profile in the mine plan.
The Kawsara target
Kawsara is located southwest along the Massawa structure and is located approximately 35km southeast of the Sabodala-Massawa processing plant. Kawsara is a 10km long anomaly that includes the Tama Toya and Sira targets. The Kawsara target has the potential to provide near-term CIL ore. The anomaly was drilled in early 2024, identifying a potentially large resource with near-surface mineralisation that is >1.50g/t and continuous over the trend. Drilling at the Kawsara, Sira and Tama Toya deposits has extended mineralisation towards the southwest where the deposit remains open.
The Makana target
The Makana target is located approximately 20km from the Sabodala-Massawa processing plant and is situated on trend between the Sofia and Kiesta deposits. Makana has the potential to provide high grade CIL ore in the nearer-term, with near-surface mineralisation. Geological drilling of the Makana target is ongoing, with follow-up drilling planned for FY-2026 to expand resources further, with a resource expected to follow.
