Our Operations

Oyu Tolgoi is one of the largest undeveloped copper reserves worldwide. Since 2012, we have been mining ore from the Oyu Tolgoi open pit. This is where all the product that we currently produce and export comes from.

After being extracted from the open pit, the ore is treated by a series of complex processes in the Oyu Tolgoi concentrator to create a fine powder called copper concentrate. This concentrate is then exported by road to international markets.

Longer term, we are looking to develop the underground phase of the mine, to access the best minerals from deep below the surface where 80 per cent of the value of Oyu Tolgoi is found.
