On 29 July 2010, the Company, Rio Tinto and Rio Tinto Atlantic, entered into the Joint Development Agreement for the development and operation of the Simandou Project in Guinea in west Africa.

In respect of the Underlying Transaction, Chinalco and Rio Tinto has entered into ancillary terms, under which Chinalco unconditionally and irrevocably guarantees to Rio Tinto the performance by the Company of all its obligations under the Simandou Joint Development Agreement in accordance with the terms thereof. In consideration of Chinalco's request, the Company proposes to grant Chinalco the Counter Guarantee by way of credit security and with a term of the Counter Guarantee contemporaneous with performance period of the Joint Development Agreement, provided that the independent shareholders' approval has been obtained.

Chinalco is the controlling shareholder of the Company. Therefore, Chinalco is a connected person of the Company for the purpose of the Hong Kong Listing Rules and the granting of the Counter Guarantee to Chinalco constitutes a connected transaction of the Company as defined under Rule14A.10(13)(e) of the Hong Kong Listing Rules. As the highest percentage ratio among all applicable percentage ratios (as defined in Rule 14.07 of the Hong Kong Listing Rules) represented by the Counter Guarantee proposed to be granted by the Company to Chinalco is more than 5%, such transaction falls within the provision under Rule 14A.17 of the Hong Kong Listing Rules, subject to the reporting, announcement and the independent shareholders' approval requirements under the Hong Kong Listing Rules.

The Company will release a separate announcement in relation to the Counter Guarantee and its details, publish and dispatch the relevant circular to the shareholders of the Company and convene the extraordinary general meeting, at which the relevant matters in relation to the Counter Guarantee will be submitted for review and approval by the independent shareholders, in due course.
