Top Peru gold miner to weigh copper growth if recovery extends

Peru’s biggest precious-metals producer will consider taking a deeper dive into copper if prices of the industrial metal keep rising. Cia. de Minas Buenaventura is tripling annual output at its Marcapunta copper mine to about 60,000 metric tons. Another expansion would take it to 100 000 tons, making Marcapunta one of Peru’s 10 largest mines, CEO Victor Gobitz said. Buenaventura subsidiary El Brocal operates the mine.
