INTRODUCTION

On 25 October 2010, at the Fifth Meeting of the Fourth Session of the Board, all Directors including the independent non-executive Directors (other than Mr. Xiong Weiping and Mr. Lv Youqing, who had abstained from voting by reason of their holding management positions in Chinalco), having considered Chinalco's request, approved the provision of the Counter Guarantee by the Company to Chinalco. The Board has also approved the formation of the Independent Board Committee to advise the Independent Shareholders in respect of the granting of the Counter Guarantee and the appointment of an independent financial adviser to provide independent financial advice to the Independent Board Committee and the Independent Shareholders in respect of the granting of the Counter Guarantee. For further information on the relevant Board resolution passed on 25 October 2010, please refer to the announcement of the Company dated 25 October 2010.

II.

THE COUNTER GUARANTEE

The proposed principal terms of the Counter Guarantee are set out as follows:

Grantor:

The Company

Grantee:

Chinalco

Nature of the Counter Guarantee:

Unconditional and irrevocable

Counter Guaranteed Obligations:

The Company guarantees that it shall duly perform its obligations under the Simandou Joint Development Agreement. In the event that the Company fails to perform its obligations under the Simandou Joint Development Agreement and as a result of which Chinalco has to perform such obligations as required under the Guarantee, the Company shall pay to Chinalco all its actual economical loss arising therefrom.

Counter Guaranteed Amount:

The amount actually paid by Chinalco in accordance with the terms of the Guarantee, which shall not exceed the corresponding amount of the Company's liability under the Simandou Joint Development Agreement.

Term:

The term is contemporaneous with the Company's performance period of the Simandou Joint Development Agreement and shall be extended to cover any period in which the Company has any outstanding liability or obligation under or in respect of the Simandou Joint Development Agreement.

Governing Law:

PRC laws

As at the date of this announcement, the terms of the Counter Guarantee have been agreed between the Company and Chinalco, but the Counter Guarantee has not been executed by the Company pending approval by the Independent Shareholders at the AGM.

III.

REASONS FOR AND BENEFITS EXPECTED TO ACCRUE TO THE COMPANY FROM THE COUNTER GUARANTEE

Participation in the Simandou Project signifies a significant step in the expansion of the Company's business scope to other energy and mineral resources business and provides an invaluable opportunity for the Company's future growth in iron ore production. It also enhances the Company's development potentials and increases the value of the Company. While Chinalco guaranteed to Rio Tinto the performance by the Company of all its obligations under the Simandou Joint Development Agreement, the Company is of the view that it has the financial resources to perform all its obligations under the Simandou Joint Development Agreement and the provision of the Guarantee by Chinalco and the proposed Counter Guarantee will not impose any additional liability on the Company. The Board, having duly considered the request by Chinalco for the provision of the Counter Guarantee, believes that as the Simandou Project is beneficial to the strategic growth of the Company, it is in the interest of the Company and its shareholders as a whole to grant the Counter Guarantee in favor of Chinalco. Having considered the above, the Directors (including the independent non-executive Directors) are of the view that the Counter Guarantee is on normal commercial terms which are fair and reasonable and in the interests of the Company and its shareholders as a whole.
