Ivanhoe Mines Ltd. (TSX: T.IVN, Stock Forum) is set to unveil the latest plans for developing the giant Oyu Tolgoi copper-gold project in Mongolia.


The plan will be released prior to the opening on North American stock markets on Tuesday morning, the company said, adding that Chairman Robert Friedland will discuss the plan a few hours later during a conference in Miami.


Rio Tinto PLC has a 22% stake in Ivanhoe, which in turn owns 66% of Oyu Tolgoi. The balance is held by the government of Mongolia.


The new integrated development plan is a comprehensive update of the original 2005 plan and supports Ivanhoe Mines’ commitment to advance Oyu Tolgoi into full construction, with production of copper and gold expected to begin in 2013.
