Oyu Tolgoi, Umnugobi - On March 15, 2011 Oyu Tolgoi announced that there had been a fire in the head frame of the No. 2 Shaft. At that time, the company indicated it would provide an update on developments.

The investigation of the fire has now been completed by both the police and Oyu Tolgoi’s internal investigation team.

The company’s investigation has resulted in a range of changes in procedures to ensure that such an event will not occur again.

There were no injuries during the fire and there will be no impact on the commencement of production.
