Rio Tinto has successfully completed its off-market buy-back of Rio Tinto Limited shares, which was increased to A$750 million from the indicative A$700 million announced due to strong demand. The Buy-Back Price was A$63.67 per Rio Tinto Limited share, which represented a discount of 14 per cent to the Market Price1.
