SUPPLEMENTAL CIRCULAR

TO

THE CIRCULAR TO SHAREHOLDERS DATED 9 APRIL 2009

RELATING TO

PROPOSED ADDITIONAL AMENDMENT TO

THE ARTICLES OF ASSOCIATION

AT THE 2008 AGM

1.

INTRODUCTION

This supplemental circular should be read together with the circular to the Shareholders dated 9 April 2009 (the "Circular"), which contains, among other matters, proposed amendments to the Articles of Association. Unless otherwise defined in this supplemental circular, terms used herein shall have the same meanings as those defined in the Circular.

LETTER FROM THE BOARD OF DIRECTORS

2.

PROPOSED ADDITIONAL AMENDMENT TO THE ARTICLES OF ASSOCIATION

At the AGM which will be held as originally scheduled, approval of the Shareholders will be sought to amend Article 13 of the Articles of Association in order to expand the scope of business of the Company to include materials inspections and analysis.

The proposed amendment to Article 13 of the Articles of Association is set out as Special Resolution No. 15 in the Supplemental Notice of the 2008 AGM and was submitted to the Company by Aluminum Corporation of China, the controlling shareholder of the Company holding directly approximately 38.56% of the issued shares of the Company, pursuant to Article 67 of the Articles of Association and in compliance with applicable laws.

The Directors of the Company consider that the proposed amendment to Article 13 of the Articles of Association is in the interests of the Company and its shareholders and accordingly recommend that all shareholders vote in favour of the Special Resolution No. 15 to be proposed at the forthcoming AGM.

3.

REVISED PROXY FORM

Since the proxy form (the "Proxy Form") sent together with the Circular does not contain the resolution for the proposed amendment to Article 13 of the Articles of Association as set out in this supplemental circular, a new proxy form (the "Revised Proxy Form") has been prepared and is enclosed with this supplemental circular.

In the case of H Shares, the revised proxy form shall be lodged with the registrar of H Shares of the Company, Hong Kong Registrars Limited, Shops 1712-1716, 17th Floor, Hopewell Centre, 183 Queen's Road East, Wanchai, Hong Kong, and in the case of A shares, the revised proxy form shall be lodged with the Office of the Secretary to the Board at No. 62 North Xizhimen Street, Haidian District, Beijing, the People's Republic of China 100082 as soon as possible and in any event not less than 24 hours before the time appointed for the holding of the AGM, i.e. 9:00 a.m. on Monday, 25 May 2009 (the "Closing Time").

If you are a non-registered Shareholder (i.e. your Shares are held in an intermediary (for example, a bank, a custodian or a securities broker) or registered in the name of your nominee), you will not receive the Revised Proxy Form. You have to give instruction to your intermediary/nominee to vote on your behalf, or if you wish to attend and vote at the AGM, you should arrange with your intermediary/nominee directly to obtain an authorisation.

A H Shareholder who has not yet lodged the Proxy Form with the Company's registrar of H Shares is requested to lodge the Revised Proxy Form if he or she wishes to appoint proxies to attend the AGM on his or her behalf. In this case, the Proxy Form should not be lodged with the Company's registrar of H Shares.

- 2 -

LETTER FROM THE BOARD OF DIRECTORS

A H Shareholder who has already lodged the Revised Proxy Form with the Company's registrar of H Shares should note that:

(i)

If no Proxy Form is lodged with the Company's registrar of H Shares, the Revised Proxy Form will be treated as a valid proxy form lodged by him or her if correctly completed.

The proxy so appointed by the H Shareholder will be entitled to vote at his or her discretion or to abstain on any resolution properly put to the AGM other than those referred to in the notice convening the AGM and the Proxy Form, including a resolution for the proposed amendment to Article 13 of the Articles of Association set out in this supplemental circular.

(ii)

If the Revised Proxy Form is lodged with the Company's registrar of H Shares prior to the Closing Time, the Revised Proxy Form will revoke and supersede the Proxy Form previously lodged by him or her. The Revised Proxy Form will be treated as a valid proxy form lodged by the H Shareholder if correctly completed.

(iii)

If the Revised Proxy Form is lodged with the Company's registrar of H Shares after the Closing Time, the Revised Proxy Form will be invalid. However, it will revoke the Proxy Form previously lodged by the H Shareholder, and any vote that may be cast by the purported proxy (whether appointed under the Proxy Form or the Revised Proxy Form) will not be counted in any poll which may be taken on a proposed resolution. Accordingly, H Shareholders are advised not to lodge the Revised Proxy Form after the Closing Time. If such H Shareholders wish to vote at the AGM, they will have to attend in person and vote at the AGM themselves.

Shareholders are reminded that completion and delivery of the Proxy Form and/or the Revised Proxy Form will not preclude Shareholders from attending and voting in person at the AGM or at any adjourned meeting should they so wish.

Important:

The Proxy Form despatched together with the Circular is superseded by the Revised Proxy Form enclosed herewith.

Yours faithfully,

For and on behalf of the board of Directors of

Aluminum Corporation of China Limited*

Liu Qiang

Company Secretary
