Rio's Argyle diamond mine in the Kimberley.

Rio Tinto’s diamond float moves to lift-off

Western Australia’s big Argyle diamond mine appears destined to shine as a key part of a new company being packaged by mining giant Rio Tinto for listing on the London stock exchange.

Other mines and exploration assets in Rio Tinto’s worldwide diamond portfolio will also be tipped into a float which industry sources say will emerge as a multi-billion dollar specialist diamond business.

Finding a way out of diamonds, which sit oddly alongside Rio Tinto’s speciality of bulk and base metal commodities such as iron ore, coal, copper and aluminium, has been on the company’s agenda since late last year.
