Jacobs Engineering to build Rio Tinto’s US$5.3bil Mongolian mine

MELBOURNE: Jacobs Engineering has won the main contract to build the US$5.3bil Oyu Tolgoi underground copper and gold mine in Mongolia, the companies said.

Development of the underground mine at Oyu Tolgoi is key to operator Rio Tinto’s ambitions to expand in copper and for the growth of the Mongolian economy, which has suffered with the global commodities slump.
