Rio Tinto has said it would issue $1.2bn of 10-year bonds, allowing the Anglo-Australian mining company to repay debts due next year.
It said it had priced the 10-year fixed rate debt securities with a 3.75 per cent coupon.
They will be issued by Rio Tinto Finance and will mature on 15 June 2025.
Rio Tinto also issued a notice of redemption for its 2.5 per cent notes due 20 May 2016 and 2.25 per cent notes due 20 September 2016.
It said that $1.2bn of this was still outstanding, and that the redemption date is 11 July 2015.
