Antofagasta's profit slumps on rising costs, Chile drought
Antofagasta posted a fall in half-year profit on Thursday, as higher costs, lower grades and a persistent drought in Chile hit the miner's copper production. It said it would slash its interim dividend to 9.2 cents per share from a record 23.6 cents last year, joining fellow miners including Rio Tinto and Anglo American in lowering payouts after last year's bonanza.
