Following BHP Billiton's earlier move to divest all from its diamond business, Rio Tinto is also undertaking a review of its diamond operations leading to a possible divestment of its assets in Australia, Canada and India, which seemed no longer fit to its business strategy.

According to an issued statement of Rio Tinto, the world's third largest mining firm, the Rio Tinto has begun a strategic review of its diamond business that will include exploring a range of options for potential divestment of its diamond interests.

Rio Tinto currently owns the Argyle mine in Australia, a 78% equity in Murowa, Zimbabwe, a 60% in Canada's Diavik project, and India's advanced diamonds project called Bunder.

Harry Kenyon-Slaney, chief executive Diamonds & Minerals, said "We regularly review our businesses to ensure they remain aligned with Rio Tinto's strategy of operating large, long-life, expandable assets.

"The diamonds market outlook is very positive, with demand growing strongly and lack of new discoveries limiting supply. We have a valuable, high quality diamonds business, but given its scale we are reviewing whether we can create more value through a different ownership structure.

"This process may take some time. We're committed to keeping stakeholders informed about any key developments, and in the meantime are reassuring employees and the governments in the states and countries where we operate that it is very much business as usual."

Rio Tinto Diamonds

Rio Tinto operates a fully integrated diamonds business from exploration through to sales and marketing. It is one of the world's major diamond producers through its 100 per cent control of the Argyle mine in Australia, 60 per cent of the Diavik mine in Canada, a 78 per cent interest in the Murowa mine in Zimbabwe. These three mines allow Rio Tinto to produce the full range of diamonds for all market segments. Rio Tinto also has an advanced diamond project, Bunder, in India.

Rio Tinto's share of the production from its three operating diamond mines is sold through its sales and marketing headquarters in Antwerp, with representative offices in Mumbai, Hong Kong and New York. It also operates a niche cutting and polishing factory in Perth for the rare pink diamonds from its Argyle mine. Rio Tinto is a leading supporter of the Kimberley Process as well as a founding member of Responsible Jewellery Council.

Rio Tinto is a leading international mining group headquartered in the UK, combining Rio Tinto plc, a London and New York Stock Exchange listed company, and Rio Tinto Limited, which is listed on the Australian Securities Exchange.

Rio Tinto's business is finding, mining, and processing mineral resources. Major products are aluminium, copper, diamonds, thermal and metallurgical coal, uranium, gold, industrial minerals (borax, titanium dioxide and salt) and iron ore. Activities span the world and are strongly represented in Australia and North America with significant businesses in Asia, Europe, Africa and South America.
