IVN Turquoise Hill Resources Ltd.

The Board of Directors of Ivanhoe Mines Ltd. (TSX: IVN)(NYSE: IVN)(NASDAQ: IVN) announced today that it has amended the shareholders' rights plan previously adopted on April 5, 2010. The amendments to the plan can be summarized as follows:

--  the definition of "Acquiring Person" has been revised to enable a person
who becomes the beneficial owner of 20% or more of the common shares
through a combination of listed provisions to acquire an additional 1%
of Ivanhoe's shares without triggering the plan;
--  the definition of "Beneficial Ownership" has been revised to delete the
reference to ownership by way of "Derivative Contracts";
--  the definition of "Exempt Acquisition" has been revised to cap the
exemption for issuances under incentive plans and to modify the
provision related to permitted treasury issuances; and
--  the shareholder approval provision has been revised to clarify that
separate shareholder approvals of the plan will exclude both "Acquiring
Persons" and "Grandfathered Persons".

The amended plan currently is in effect, subject to confirmation through a vote of shareholders at Ivanhoe Mines' annual general and special meeting to be held in Vancouver May 7, 2010.

The Toronto Stock Exchange has accepted notice of the amended plan, subject to, among other conditions, confirmation by Ivanhoe's shareholders.
