3.	PRESS RELEASE

The press release was issued on July 27, 2012 and was disseminated through the facilities of recognized newswire services. A copy of the press release was filed on SEDAR.

4.	SUMMARY OF MATERIAL CHANGE

On July 27, 2012 (the “ Closing Date ”), the Company completed its previously announced rights offering (the “ Rights Offering ”) by issuing a total of 259,558,050 new common shares (“ Common Shares ”) in its capital for aggregate gross proceeds of (the “ Proceeds ”).

5.	FULL DESCRIPTION OF MATERIAL CHANGE

On the Closing Date, the Company completed the Rights Offering by issuing a total of 259,558,050 new Common Shares for the Proceeds, which equalled approximately US$1,819,100,624.30 (CDN$1,837,473,540.61).

The Rights Offering, originally announced on May 22, 2012, contained the following key terms:

•

each shareholder of the Company, as of June 19, 2012, was issued one right (a “ Right ”) for each Common Share held;

•

pursuant to a basic subscription privilege (the “ Basic Subscription Privilege ”), each holder of Rights was, subject to applicable securities laws, entitled to purchase 7 Common Shares for every 20 Rights held or exercise Rights in increments of 3, with 3 Rights exercisable for 1 Common Share (or if the exercise of a number of Rights would otherwise entitle a holder thereof to a fractional number of Common Shares, the holder’s entitlement was reduced to the next lowest whole number of Common Shares), in consideration for the payment of a subscription price of either, at the subscriber’s election, US$7.00 or CDN$7.17 per Common Share;

•

holders of Rights who exercised their Basic Subscription Privilege in full were also entitled, pursuant to an additional subscription privilege (the “ Additional Subscription Privilege ”), to subscribe for additional Common Shares, if any, that were otherwise not subscribed for pursuant to the Basic Subscription Privilege, on a pro rata basis amongst those subscribers subscribing for Common Shares under the Additional Subscription Privilege and upon to the same economic terms and conditions as the Basic Subscription Privilege; and

•

under the previously announced Memorandum of Agreement (the “ MOA ”) ¹ transaction, as amended, with Rio Tinto International Holdings Limited and Rio Tinto South East Asia Limited (together, “ Rio Tinto ”), Rio Tinto agreed to provide a standby commitment (the “ Standby Commitment ”) pursuant to which it agreed to purchase any Common Shares not otherwise taken up under the Basic Subscription Privilege and the Additional Subscription Privilege in exchange for a standby commitment fee equal to 4% of the gross proceeds of the Rights Offering.

Approximately 99.2% of the Common Shares were taken up under the Basic Subscription Privilege with the balance taken up under the Additional Subscription Privilege, and as a result no Common Shares were issued pursuant to the Standby Commitment. Rio Tinto exercised all of its respective Rights under the Basic Subscription Privilege and participated in the Additional Subscription Privilege. As a result of the Rights Offering, Rio Tinto’s stake in the Company increased from 50.9% to 51.0%.

As a result of the Rights Offering and as of the Closing Date, there were 1,001,288,734 Common Shares issued and outstanding.

Under the MOA, the Company is obligated to use the Proceeds to (i) pay down the principal amount, if any, outstanding under its US$1.5 billion bridge loan facility (the “ Bridge Facility ”) made available by Rio Tinto, and (ii) to use the remainder of the Proceeds to continue the development of its Oyu Tolgoi Project (the “ OT Project ”) in Mongolia until the scheduled start of initial production from the open-pit mine during the second half of 2012, and to fund additional expenditures to ramp-up commercial production during the first half of 2013 as part of the OT Project’s first phase of development. As of the date of this material change report, no money has been drawn down under the Bridge Facility.
