Rio Tinto and Antofagasta share rise as production reports impress

  • Shares in Rio Tinto Ltd (LSE:RIO, ASX:RIO, OTC:RTNTF) and Antofagasta PLC (LSE:ANTO) both rose 2% after the giant miners posted operational updates for the second quarter. A day after announcing that iron ore chief Simon Trott will take over as CEO next month, RIO's current boss hailed "excellent" performance from the group's mines, with record production from the bauxite business and from the massive copper-gold deposit Oyu Tolgoi in Mongolia.
