Copper and Molybdenum production at Freeport McMoRan's Cerro Verde mine in Peru has not been materially affected by an indefinite strike that started this morning, said a spokesman on Wednesday.
Cerro Verde is Peru's No. 3 copper producer, and yielded 312,336 tonnes of the metal in 2010.
The company did not specify how it had averted an impact on production but hired temporary workers to compensate for a two-day strike last week.
