Chile’s copper production increased 18.9% in the first quarter of 2018 from the same period a year earlier, Chilean copper commission Cochilco said on Tuesday. Production this year was boosted by a low basis for comparison following an historic strike last year at BHP’s Escondida copper mine, the world’s largest. Escondida tripled its production in the first quarter of 2018 to 322 700 t, Cochilco said.
