About Oyu Tolgoi Mine

Oyu Tolgoi is developing a mine that will exploit one of the world’s largest undeveloped copper-gold resources. The resource is so large that the mine is expected to be operating for at least 50 years.
The Oyu Tolgoi deposit was discovered by Turquoise Hill Resources, a Canadian company, in 2001. Rio Tinto, one of the world’s largest companies, is a major shareholder in Turquoise Hill Resources and has been actively involved in the project since 2005. In 2010, Rio Tinto formally assumed management of the project on behalf of all shareholders. Oyu Tolgoi is owned by Turquoise Hill Resources (66 per cent) and Erdenes Oyu Tolgoi (34 per cent). Erdenes Oyu Tolgoi is wholly owned by the Government of Mongolia.
