ENDEAVOUR Mining has suspended underground mining at its Mana gold mine in Burkina Faso after part of an access ramp subsided, restricting access to two underground portals.
The incident occurred on October 28 on the ramp leading to the depleted Wona open pit, affecting access to the Dangouna and Aviera portals. No one was injured and all underground workers were evacuated.
Mining at all three active underground portals has been halted while Endeavour carries out geotechnical analysis and assesses remediation work. The company said the Wona portal remained accessible and it was considering restarting and accelerating mining there as part of efforts to limit the effect on production.
Endeavour said it remained on track to meet its 2026 group production and all-in sustaining cost forecasts. It will give an update on the remediation plan when it reports third-quarter results on November 12.
Mana produced 173,000 ounces of gold in 2025 and is forecast to produce between 155,000 oz and 180,000 oz this year. The mine shifted to a fully underground operation in 2024 and Endeavour is aiming to extend its life beyond 10 years by expanding underground deposits and assessing nearby open-pit targets.
The disruption comes as Endeavour continues to navigate a changing operating environment in Burkina Faso, where it also owns the Houndé mine.
CEO Ian Cockerill said in July that conditions in the country had become more stable over the previous six to nine months and that the government appeared to be more in control.
However, the government has taken a more interventionist approach to mining. Miningmx previously reported that it had required mine supplies to be sourced through a state-owned company, a move Cockerill described as initially disruptive.
