Copper prices to remain strong:
International copper prices, while subject to sharp volatility, will remain strong this year, the chief financial officer of Chilean state copper giant Codelco said Tuesday.
Copper prices surged more than 3 per cent to 13-month highs on Wednesday, reaching above $3 per pound in New York, as the dollar weakened and BHP Billiton declared force majeure at the world's fourth-largest copper mine.
