The No.2 shaft is 10 metres in diameter and will be used for access, production and ventilation. The ore will be mined from the Hugo North Lift.

The Oyu Tolgoi mine is located in the south Gobi region of the country. At peak production from 2024 to 2026, the project is expected to produce 600,000 tonnes of copper annually.

On Jan. 8, 2018, Turquoise Hill declared force majeure at Oyu Tolgoi due to a protest by Chinese coal transporters who used a large number of vehicles to block the main access road to China. On Jan. 19, Oyu Tolgoi concentrates were again being transported, but force majeure remains in effect until a stable transport corridor is established.
