Indefinite strike today at Peru's largest copper mine Workers at Freeport-McMoRan's (FCX.N) Cerro Verde (CVE.LM) started an indefinite strike on Friday that halted output of about 40,000 tonnes per month at Peru's top copper mine, a union official said on Friday.
Copper prices rose following the latest disruption to global supplies, amid a monthlong strike at BHP Billiton's (BLT.L) (BHP.AX) Escondida mine in Chile and a dispute over export rights at Freeport's Glasberg mine in Indonesia.
