Rio Tinto’s $5.3bn Mongolian mine finds its contractors in Jacobs Engineering
The company provides industrial maintenance, construction and maintenance management technology.
"Following the final notice to proceed for the underground development last month, this contract is a critical piece as we ramp up towards full construction," Oyu Tolgoi Chief Executive Andrew Woodley said in a statement.
The expansion of the $5.3bn Oyu Tolgoi underground copper and gold mine was announced by Rio Tinto Group’ CEO Jean Sebastian Jacques last month.
The first stage of Oyu Tolgoi was approved in 2010 and started producing in 2013.
