On August 02, 2012, Ivanhoe Mines announced that the company's name change to Turquoise Hill Resources Ltd. now has gone into effect. The new name was approved by shareholders at the company's annual meeting on June 28, 2012. 

The company’s new trading symbol will be “TRQ” and will become effective at the opening of trading on the Toronto Stock Exchange, the New York Stock Exchange and the NASDAQ Stock Market on August 08, 2012. Chief Executive Officer of Turquoise Hill Resources Kay Priestly said, “Changing our name to Turquoise Hill Resources marks another milestone in our corporate history.
