3. NEWS RELEASE

The news release was issued on January 18, 2012 and was disseminated through the facilities of recognized newswire services. A copy of the news release was filed on SEDAR.

4. SUMMARY OF MATERIAL CHANGE

The Company’s Board of Directors (the “Board”) has accepted a recommendation by a special committee of independent directors and resolved to place before the Company’s shareholders at the next annual meeting of shareholders, and recommend that shareholders vote in favour of, a resolution to terminate the Company’s Shareholder Rights Plan (“SRP”). The Board also resolved to take steps to ensure that the SRP would not be inadvertently triggered prior to the annual meeting of shareholders by delaying the separation of the rights from the common shares until the meeting at which time it is expected that the shareholders will vote to terminate the SRP. The Company subsequently entered into an agreement with Rio Tinto International Holdings Limited (“Rio Tinto”) to amend the Private Placement Agreement dated October 18, 2006 (“PPA”) to enable Rio Tinto to acquire additional common shares on a basis that would be exempt from the SRP.

5. FULL DESCRIPTION OF MATERIAL CHANGE

The Board has accepted a recommendation by a special committee of independent directors and decided that the interests of the Company’s shareholders and the Company’s strategic objectives would be best served by the termination of the SRP. Since formal termination of the SRP requires the approval of the Company’s shareholders, the Board has resolved to place before the shareholders at the next annual meeting, set for May 11, 2012, a resolution to terminate the SRP and the Board will formally recommend that shareholders vote in favour of the resolution.

An arbitrator’s decision issued on December 12, 2011 suggested that the Board seriously consider whether preserving the application of the SRP to any Rio Tinto common share purchases was in the best interests of the Company.

Following the arbitrator’s ruling, the Board unanimously approved the formation of a special committee, comprised of members of the Board’s Corporate Governance Committee, to conduct an evaluation of the arbitrator’s decision, with the assistance of independent legal counsel. The committee consisted entirely of independent directors and did not include any representatives of Rio Tinto or the Company’s management. The decision to recommend termination of the SRP was unanimously supported by the participating directors; directors who are Rio Tinto employees did not take part in the discussion or vote.

Rio Tinto, which had been restricted to a 49% ownership stake in the Company prior to the expiry on January 18, 2012 of the standstill restrictions in the PPA, had recently advised the Board of its intention to purchase additional common shares of the Company regardless of the status of the SRP, to enable Rio Tinto to increase its ownership level to more than 50%.

As part of the decision to recommend that shareholders vote to terminate the SRP, the Board resolved to take steps to ensure that the SRP would not be inadvertently triggered prior to the May 2012 annual meeting by delaying the separation of the rights from the common shares until the meeting. While the SRP technically will remain in effect until the shareholders vote to terminate it at the annual meeting, the Board has exercised its discretion under the SRP to defer the Separation Time – the activation point, nominally occurring 10 days after the announcement of a triggering share acquisition, at which shareholders could exercise rights to acquire additional discounted common shares.

The Board also resolved to explore other means to prevent the inadvertent triggering of the SRP, including by way of an amendment to the PPA, which could enable Rio Tinto to acquire additional shares through a transaction that would be exempt from the SRP. The Company subsequently entered into an agreement with Rio Tinto to amend the PPA. The effect of this amendment is that all acquisitions of common shares by Rio Tinto prior to the May 2012 annual meeting will be exempt from the SRP. The amendment also formalizes the Company’s commitment to place before the Company’s shareholders at the next annual meeting of shareholders, and recommend that shareholders vote in favour of, a resolution to terminate the SRP. Rio Tinto has also agreed in the amendment to vote its common shares in favour of the termination of the SRP.
