Shareholders Approve Kazakhmys Restructuring

Kazakhmys PLC ("Kazakhmys" or the "Company") announces that at its General Meeting held today, the Resolutions put to Shareholders in relation to the proposed restructuring of the Company, as announced on 23 July 2014, were duly passed on a poll.

Key points of restructuring

· The restructuring is a key step in delivering the Company's strategic goals:

o Focused on copper in Central Asia

o Dominated by large scale, low cost, open pit mines

· The Transaction involves the transfer of mature assets in the Zhezkazgan and Central Regions to Cuprum Holding, a private company owned by Vladimir Kim and Eduard Ogay

· The restructuring creates a more viable future for the Disposal Assets and their surrounding communities

· Kazakhmys will retain five mines, with high copper grade, low sustaining capital expenditure and a cash generative profile

· The Company will significantly increase future production through three major growth projects

· Completion remains subject to regulatory approvals in Kazakhstan:

o Completion expected by the end of 2014

o Kazakhmys to be renamed KAZ Minerals PLC on completion

Oleg Novachuk, Chief Executive of Kazakhmys, commented: "This is a transformational event for the Company. Today's vote is a key step toward achieving our strategic aim of production based on a portfolio of highly competitive assets, backed by an industry leading growth profile and providing attractive returns for all stakeholders."

Result of General Meeting

The poll results showing the number of votes received for and against the Resolutions are shown below.

In accordance with the Listing Rules, each of Vladimir Kim and Eduard Ogay, and their respective associates, have not voted their interest in Ordinary Shares in respect of Resolution 1 (the Transaction Resolution). Furthermore, although eligible to vote and supportive of the Transaction, Oleg Novachuk has not voted his interest in Ordinary Shares in respect of Resolution 1 so as to allow for Resolution 1 to be voted upon by the remaining Independent Shareholders. Therefore, the poll votes received for Resolution 1 represent approximately 31 per cent. of the total number of Ordinary Shares eligible to vote. The poll votes received for Resolution 2 represent approximately 63 per cent. of the total number of Ordinary Shares eligible to vote.

The Company currently holds 11,701,830 Ordinary Shares in treasury which do not carry voting rights.

Full details of the Resolutions passed, together with explanatory notes, are set out in the Shareholder Circular including the Notice of General Meeting dated 23 July 2014 which is available on the Company's website at www.kazakhmys.com.

Resolution 1 was proposed as an ordinary resolution and Resolution 2 was proposed as a special resolution.

* 'Vote Withheld' is not a vote in law and is not counted in the calculation of the proportion of the votes 'For' and 'Against' a resolution.

In accordance with LR 9.6.2 of the UK Listing Authority, Kazakhmys has submitted copies of the Resolutions passed at its General Meeting to the National Storage Mechanism which will shortly be available for inspection at: www.hemscott.com/nsm.do.
