Endeavour Mining has stopped underground mining at its Mana gold mine in Burkina Faso after part of an access ramp sank on October 28. Nobody was hurt, and the company says it remains on track for its group targets.
At a glance
- Mining has stopped at all three active underground entrances while specialists assess the ground.
- Endeavour will outline a repair plan with its third-quarter results on November 12.
- An analyst at National Bank Financial expects repairs to take one to two quarters.
Background
Mana is one of Endeavour's two producing gold mines in Burkina Faso, alongside Houndé, and became a fully underground operation in 2024. Endeavour, listed in Toronto and London, produces about 1.2 million ounces of gold a year across West Africa. Subsidence is when the ground sinks or collapses.
What happened
Endeavour suspended underground mining at Mana after part of the access ramp through the depleted Wona open pit sank on October 28, it said on Monday, MINING.COM and MiningMX reported. The subsidence restricted access to the Dangouna and Aviera underground entrances.
Workers were evacuated, nobody was injured and local authorities were notified. Mining has stopped at all three active underground entrances while specialists assess ground stability and repairs.
What it means for output
Endeavour said it remains on track for its group production and cost targets even if Mana produces nothing more this quarter. Its 2026 group guidance is 1.09 million to 1.27 million ounces.
Mana was already struggling. Endeavour warned in July that the mine would fall below the bottom of its original 155,000 to 180,000 ounce target, and first-half output fell about 22% to 68,000 ounces.
What comes next
Endeavour is considering restarting and speeding up mining through the Wona entrance, which is still accessible, and drawing on nearby open pits. The overall impact depends on how long repairs take, which National Bank Financial analyst Mohamed Sidibé estimated at one to two quarters.
In July, Endeavour paused work at Aviera to monitor a surface crack in the same pit. Sidibé said the new event appears to lie on a parallel structure, but it is too early to say if they are related.
Our read
Outlook: neutral. Mana is a small part of global gold supply, and Endeavour still expects to meet its group targets.
What to watch
- Endeavour's repair plan, due with its third-quarter results on November 12.
- Whether mining restarts through the Wona entrance.
- Endeavour's 2026 production against its 1.09 million to 1.27 million ounce guidance.

Mining Production
Underground mining has stopped at Mana, which was already expected to miss its original output target.
What could lift prices
- A halt at a producing mine slightly reduces gold supply.
- Repairs could take up to two quarters.
What could weigh on prices
- Endeavour still expects to meet its group production targets.
- Mana is a small share of global gold output.
Country impact
| Country | Impact | Reason |
|---|---|---|
| Burkina Faso | Medium | One of its two Endeavour gold mines has halted underground work. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Gold Mining | Negative | Ground instability has halted a producing underground mine. |
Who gains, who loses
- Mana workers: They were evacuated safely, with no injuries.
- Endeavour Mining: It loses underground output at a mine already behind target.
Other ways this could play out
- If repairs finish within a quarter, Mana's lost output could be limited.
- If ground problems spread, Mana could stay shut for longer.
Price risks
- Further subsidence could affect the Wona entrance as well.
- Repair costs could add to Mana's already high costs.
