Peter Meredith, Deputy Chairman of Ivanhoe Mines (TSX: IVN)(NYSE: IVN)(NASDAQ: IVN), announced today that Mongolian diplomat Galsan Batsukh has been nominated to become Chairman of the Board of Directors of Oyu Tolgoi LLC, which is building, and will operate, the Oyu Tolgoi copper-gold project in southern Mongolia.

"Mr. Batsukh has been closely associated with the Oyu Tolgoi story virtually since it began with Ivanhoe's exploration drilling in 2001, when he was appointed Mongolia's first ambassador to Canada. Now we are proud to nominate him for this key role with the team that is building the mining complex, which is the largest industrial development in Mongolia's history," Mr. Meredith said.

"Mr. Batsukh's experience in international affairs and consensus building, and his understanding of the expectations that the Mongolian people have in supporting the development of their resources, will be an invaluable asset to the company and the process."

Oyu Tolgoi, which will become one of the world's largest porphyry copper-gold mines, is scheduled to be in commercial production in 2013 following the completion of a comprehensive, long-term Investment Agreement last October between Ivanhoe Mines, its strategic partner Rio Tinto and the Government of Mongolia.
