Chilean union will extend strike at Escondida mine

The largest union at Chile’s Escondida copper mine voted to “indefinitely” extend a strike at the mine, which is controlled by global diversified miner BHP Billiton Ltd. (BHP, BHP.AU), union leader Jose Vidal said Friday.

Members of 2,350-strong Escondida Mine Workers Union No. 1 “unanimously voted” to extend the work stoppage, which began Thursday night and was initially slated to end 24 hours later at 8 p.m. EDT on Friday, Vidal told Dow Jones Newswires.
