Zinc concentrate production fell by around 15% due to a lower grade feed and harder rock forced a drop in the throughput for copper-zinc ores, although this was offset by higher milling-rates for copper-only ore. In total, 2006 saw the production of 384,200t of copper, 156,100t of zinc and 7,730t molybdenum, from 30.25Mt of ore.
