Operations Resume After Quake

A 7.9 magnitude earthquake struck northern Chile Monday night, killing eight people. The quake temporarily knocked out power at BHP Billiton’s Cerro Colorado copper mine, though operations continued running normally at Escondida, the world’s largest copper mine. Power was cut at Codelco’s largest mine, Chuquicamata, and at Radomiro Tomic mine, though operations were quickly restored.
