Kazakhmys wobbles after results

Copper miner Kazakhmys yesterday reported a 12 per cent bump in ore extraction over the first half of the year, performing better than in the year-ago period. Copper cathode production increased by seven per cent in the same period. Chief executive Oleg Novachuk said the firm would be reviewing its assets and operations. Yet the company’s shares plunged in value, falling 6.3 per cent from the previous day, despite assurances that the group would meet its targets.
