BHP losing $28m a day in strike

The largest union at Chile’s Escondida copper mine has voted to “indefinitely” extend a strike at the mine, which is controlled by BHP Billiton.

Members of the 2350-strong Escondida Mine Workers Union No 1 “unanimously voted” to extend the work stoppage, which began on Thursday night and was initially planned to end 24 hours later at 8pm on Friday, union leader Jose Vidal said.
