SANTIAGO, April 11 (Reuters) - Copper production in

Chile rose 9.8% on an annual basis to 417,000 metric tons in

February even as state-run Codelco's output dipped, the

country's copper commission Cochilco said on Thursday.

Despite the overall rise, production at Chile's embattled

copper giant Codelco, the world's largest copper

producer, dipped 1.6% to 103,700 tons.

February's rise in production was helped by a 34.1%

year-on-year rise from BHP's flagship Escondida mine,

the world's largest copper mine, which saw production reach

97,500 tons in February

Collahuasi, another major copper mine in Chile jointly run

by Glencore ( GLCNF ) and Anglo American ., saw production

rise 2.5% to 45,200 tons year-on-year in the month.
