Copper producers plan to expand mine capacity and output to record levels again this year, underlining potential additional downward pressures on prices, which have fallen steeply recently.
Prices for the red metal tumbled last week to the lowest level since 2010, amid signs of sluggish demand and the building up of inventories in China, by far the largest market for copper and most other metals. The copper market is closely watched as a gauge of global economic health.
Global copper miners – of which the largest are Codelco of Chile, Freeport-McMoRan, Glencore Xstrata and BHP Billiton – plan expansions of mine capacity that would add between 1.1m tonnes and 1.3m tonnes of copper annually to the market until 2016, according to data provider SNL Financial.
Such increases would be roughly equivalent to the annual output of Escondida, the world’s largest mine, which provides about 5 per cent of world supply.
