Roobuck’s Project – Rio Tinto Oyu Tolgoi Mine Mongolia

Rio Tinto’s Oyu Tolgoi (OT Mine), in the South Gobi region of Mongolia, is one of the largest known copper and gold deposits in the world. It is also one of the most modern, safe and sustainable hardrock mining operations in the world. When the underground is complete, it will be the world’s third largest copper mine.

Open pit mining began at Oyu Tolgoi in 2011 and the copper concentrator, the largest industrial complex ever built in Mongolia, began processing mined ore into copper concentrate in 2013. Current infrastructure at Oyu Tolgoi will allow the mine to operate for decades to come. Oyu Tolgoi is jointly owned by the government of Mongolia, which has 34% ownership, and Turquoise Hill Resources, which owns 66%. Rio Tinto owns 50.8% of Turquoise Hill Resources and manages the operation on behalf of the owners.
