Mining reported that Peruvian miner Antamina produced about 450,000 tonnes of copper in 2012 and expects similar output in 2013.

Mr Abraham Chaun CEO of Antamina said that the company will invest USD 1.3 billion this year to increase output about 30%. In 2011, Antamina produced 333,700 tonnes of the red metal or 28% of Peru’s total copper output. The mine, one of the world's biggest copper-zinc pits is run by a group of miners including BHP Billiton, Xstrata, Teck and Mitsubishi.
