The company now plans to ramp up production to 353 million tonnes per annum by 2015.
Rio Tinto chief executive Tom Albanese said that the company has delivered strong set of production results in the third quarter, including significant production from Pilbara.
"Copper, bauxite, alumina, and titanium dioxide production were all higher than in the same quarter of 2011.
"As we said at our Investor Seminar last week, markets remain volatile, but our business is resilient and our operations are performing strongly, reflecting our consistent strategy of running large, long-life, cost-competitive operations," Albanese added.
Thermal coal production increased 21% compared to third quarter of 2011, while hard coking coal production was 13% lesser than third quarter of 2011.
