Rio Tinto stock: BHP Pilbara iron ore tie-up lands as Glencore clock ticks
Rio Tinto and BHP agreed to study a Pilbara iron ore collaboration that could unlock up to 200 million tonnes of supply, linking Yandicoogina and Yandi operations. Rio shares closed at 6,355p, up 2.27%, near a year high. A major Australian shareholder questioned the value of any Glencore deal as copper prices remain high. Rio has until Feb. 5 to formalize a Glencore bid under UK rules.
