Copper Futures Climb Most in Two Weeks on Escondida Mine Strike

Copper rose the most in more than two weeks on speculation that a strike at the world’s biggest mine may worsen a global supply shortage.

A strike at BHP Billiton Ltd.’s Escondida mine entered a fifth day as Chilean labor authorities prepared to mediate talks between union and company officials. The stoppage has cost about 12,000 metric tons in lost output, said Roberto Arriagada, a union director. World consumption is set to exceed production by 377,000 tons this year, the International Copper Study Group has forecast.
