Antamina: Weaker Output to End Over Medium Term

Antamina, Peru's top copper mine, said on Friday it expects a period of weaker production to subside in "the medium term."

The mine, in which BHP Billiton (BHPLF) and Glencore (GLCNF) Xstrata (XSRAF.PK) each have 33.75 percent stakes, produced 246,851 tonnes of copper in the first eight months of 2014, 14 percent less than in the same period a year earlier.

"We are sure we will be able to reverse this in the medium term," Silvio Brigneti, Antamina's vice president of human resources and security, said in an emailed statement.
