Strike threats in the copper industry

• The eyes of the metals industry will be on Chile this week when a new pay deal will be put to workers at Escondida, the world's biggest copper mine.
• In the first nine months of 2016, Escondida produced 750K tons of copper, so the impact of a strike would likely reverberate.
• Although employees have already rejected an initial offer from operator BHP Billiton (NYSE:BHP), a final proposal will be delivered today with a vote scheduled for tomorrow.
