Codelco's molybdenum output fell 8.9% to 11,573t in January-May, mainly because of declines at its Chuquicamata, Radomiro Tomic and El Teniente mines, which offset increases at the Salvador and Andina mines.
Los Pelambres produced 3,729t, up 46.4% from January-May 2016. Collahuasi's molybdenum output fell 69.3% to 445t, while Anglo American Sur reported a 27.9% drop to 850t.
