Rio Tinto Chief Executive Mr Jakob Stausholm said “We are building a stronger Rio Tinto and delivering against our four objectives. Our operational performance has improved, as evidenced by a number of second half records being set at our Pilbara iron ore mine and rail system. We are also investing for the future, doubling our stake in the Oyu Tolgoi copper-gold project in Mongolia through the acquisition of Turquoise Hill Resources progressing the Rincon Lithium Project in Argentina and reaching milestone agreements that underpin the long-term success of our Pilbara iron ore business. He said “Despite challenging market conditions, we remain resilient because of the quality of our assets, our great people and the strength of our balance sheet. That is why we delivered strong financial results with underlying EBITDA of AUD 26.3 billion and underlying earnings of AUDD 13.3 billion, after taxes and government royalties of AUD 8.4 billion.”Rio Tinto delivered first ore from Gudai-Darri, r first greenfield iron ore mine in the Pilbara in more than a decade.
