Endeavour Mining suspends Mana mine operations in Burkina Faso after ramp subsidence

Endeavour Mining reported that an access ramp leading to the depleted Wona open pit partially subsided on October 28 in Burkina Faso. This incident restricted access to the Dangouna and Aviera underground portals at the Mana mine. Consequently, underground mining activities at all three active portals at Mana have been suspended to allow for detailed geotechnical analysis and ramp remediation work.

The incident disrupts operations at a major gold producer in West Africa. While Endeavour Mining stated it remains on track for its FY-2026 Group production and AISC guidance, the suspension of underground activities introduces operational risk and remediation costs. The company is evaluating options to mitigate the impact, including accelerating mining activities at the Wona portal.
