Sales likely missed the 1.06 billion target because output in South America was lower than expected. However earnings were bolstered on the back of rising gold sales up to 305K oz from 202K oz.

Average realized prices for copper dropped to $3.28 per pound, compared to $3.64 per pound last year. Oil and gas production also contributed to solid results. Average realized price for oil was $104.33 per barrel.
