Chile’s Escondida copper mine, owned partially by BHP Billiton and Rio Tinto, encountered a sudden strike. About 2,500 workers stopped working, initially intended to last 24 hours.
“Labor action has been galvanized in mining powerhouse Chile as unions seek to get their issues heard ahead of the November presidential election,” according to Reuters. “Escondida produced 1.1 million tonnes of copper last year, about 20 percent of the output from No. 1 copper producer Chile.”
