VOLUNTARY ANNOUNCEMENT

PROPOSED PARTICIPATION IN THE BIDDING FOR EQUITY INTERESTS OF CHINALCO SHANGHAI

This announcement is made by Aluminum Corporation of China Limited* (the "Company") on a voluntary basis.

On 22 June 2016, the Company received a letter from Aluminum Corporation of China ("Chinalco"), the controlling Shareholder of the Company, pursuant to which the Company learned that Chinalco proposed to transfer 60% of its equity interests in Chinalco Shanghai Company Limited * ("Chinalco Shanghai") by way of public tender.

On 28 June 2016, the first meeting of the sixth session of the board of Directors (the "Board") of the Company considered and approved the participation in the bidding for 60% of the equity interests of Chinalco Shanghai. As Mr. Yu Dehui and Mr. Liu Caiming, being Directors of the Company, also hold positions in Chinalco, they have abstained from voting on the Board resolution.

Chinalco was incorporated in Beijing in February 2001. The principal businesses of Chinalco include: the mining of bauxite; the overseas dispatch of business personnel undertaking the overseas projects compatible with their capability, scale and performance; management of state-owned assets and state-owned equities; production and sales of mineral products, smelted products, fabrication products and carbon products of aluminum, copper, rare earth and relevant non-ferrous metals; engagement in exploration design, general project contracting, construction and installation, equipment manufacturing, technological development, technical service and import and export businesses.

Chinalco Shanghai was incorporated in April 2012 with registered address at Room A328, No. 551 West Gaoke Road, Pudong New Area. The principal businesses of Chinalco Shangha include: domestic trade (except for special approval); import and export of cargo and technology; real estate development and operation; management of engineering projects; construction; sale of metal materials and relevant products; freight forwarding agency; warehousing (except for dangerous goods); commercial consultancy (except for brokerage); asset management; industrial investment; property management; exhibition service and others. Chinalco Shanghai holds two 5A office buildings in Shanghai Pudong New Area.

Chinalco is the controlling shareholder and a connected person of the Company. Therefore, if the Company successfully bids for 60% equity interests of Chinalco Shanghai, the transfer of 60% equity interests of Chinalco Shanghai to the Company by Chinalco will constitute a connected transaction under Chapter 14A of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited ("Hong Kong Listing Rules"). The Company will properly implement the compliance requirements under the Hong Kong Listing Rules, including announcement and independent shareholders' approval requirements (if applicable).

As at the date of this announcement, Chinalco has not conducted formal quotation of 60% equity interests of Chinalco Shanghai, and the Company and Chinalco have not entered into any agreement in respect of the transfer of equity interests of Chinalco Shanghai. The transaction will be conducted by way of public bid through assets and equity exchange and it is uncertain whether the Company will win the public bid. Investors should pay attention to investment risks.
