IVN Turquoise Hill Resources Ltd.

Robert Friedland, Executive Chairman and Chief Executive Officer of Ivanhoe Mines (TSX: IVN)(NYSE: IVN)(NASDAQ: IVN), announced today that Ivanhoe Mines has delivered a statement of defence and initiated a counter-claim as part of an ongoing arbitration proceeding launched by Rio Tinto on July 9, 2010.

The statement of defence rejects Rio Tinto's claim that the shareholders' rights plan approved by Ivanhoe Mines' shareholders on May 7, 2010, breached Rio Tinto's contractual rights under its agreements with Ivanhoe Mines.

The counter-claim contends that Rio Tinto has breached its covenants in its private placement agreement, signed with Ivanhoe Mines in October 2006, not to engage in activities that could affect control of Ivanhoe Mines without Ivanhoe's permission.

An independent arbitrator has scheduled hearings of the claim and counter-claim between January 18 and February 5, 2011.

Mr. Friedland said that the arbitration proceeding should not have any negative impact on the rapid pace of full-scale construction now underway at Oyu Tolgoi to bring the mining complex into production ahead of schedule in 2012.
