Ivanhoe Mines Reaffirms Support for Company's Plan That Protects Shareholders' Rights

David Huberman, lead independent Director of the Ivanhoe Mines Board of Directors and Chair of the Board's Corporate Governance Committee, said today that the company would continue to support its Shareholders' Rights Plan in an arbitration proceeding initiated by Rio Tinto plc.

Mr. Huberman said Ivanhoe Mines firmly believes that the Shareholders' Rights Plan, adopted in April this year, is not in breach of any of Rio Tinto's existing contractual rights. However, the Rights Plan does restrict Rio Tinto - and other shareholders and third parties - whether acting alone or in concert with another party, from acquiring additional Ivanhoe shares in the market beyond the amounts provided for in existing contractual arrangements unless an offer is made to all shareholders.

Rio Tinto, which presently owns 29.6% of Ivanhoe Mines, claimed in a filing for arbitration last Friday, July 9, that the Ivanhoe Shareholders' Rights Plan breached some of Rio Tinto's rights under the October 2006 private placement agreement between Rio Tinto and Ivanhoe Mines. Nothing in the private placement agreement prohibits Ivanhoe Mines from implementing a Shareholders' Rights Plan.

The Ivanhoe Mines Rights Plan is intended to protect all shareholders from coercive or creeping takeovers, while allowing takeover bids that are made to all shareholders and that satisfy the conditions of Permitted Bids. The Rights Plan also provides Ivanhoe's Board of Directors with additional time to consider any bid and, if applicable, to explore alternative transactions that would maximize value for shareholders.

The Rights Plan was approved by all members of the Ivanhoe Board on April 5, with the exception of the Rio Tinto appointee who opposed the Plan. Formal ratification of the Rights Plan was recommended by independent proxy advisers Risk Metrics and Glass Lewis & Co. and the Plan was overwhelmingly approved by 95% of Ivanhoe's minority shareholders who voted on May 7.

Mr. Huberman said Ivanhoe Mines values its ongoing relationship with Rio Tinto and the support Rio Tinto is continuing to provide to Ivanhoe Mines in advancing the construction of the Oyu Tolgoi copper-gold mining complex in southern Mongolia. "Ivanhoe intends to continue to work in good faith with Rio Tinto to realize our shared objective of bringing the world-class Oyu Tolgoi mine into production in 2013 and begin delivering its very substantial benefits to present and future generations of stakeholders."
