LONDON 1100 GMT
Underground operations at the Oyu Tolgoi copper mine in Mongolia are being progressively restarted following completion of safety reviews.
A seismic event on 29 October 2026 led to a localised rockfall confined to a temporary storage zone adjacent to the production area, with no structural impact to the cave or its operating infrastructure.
Two employees continue to receive treatment for non-life-threatening injuries.
Oyu Tolgoi is working closely with the relevant authorities, and continues to support our employees and contractors.
