Bomboré Mine

The Company owns a 90% interest in the Bomboré Gold Mine with the government of Burkina Faso retaining a 10% carried interest. Bomboré is situated 85 km east of the capital city of Ouagadougou and is readily accessed by paved international highway thereby offering excellent infrastructure and simple logistics.

Bomboré was constructed on-time and under budget and achieved commercial production of its Phase I oxide plant on December 1, 2022, which has successfully operated above its planned nameplate at a processing rate of 5.9Mtpa. Orezone is currently constructing an independent, parallel 2.5Mtpa hard rock plant which will increase production to >170,000oz gold/year, commencing in Q4-2025. A secondary hard rock expansion, adding another 2.5Mtpa processing capacity and increasing gold production to 220,000 - 250,000oz/year, is being evaluated for acceleration with commissioning in late 2026.
