Doré Copper has consolidated a large land package of brownfield projects in and near Quebec's Chibougamau prolific mining camp that has produced 1.6 B lbs of copper and 4.4 M oz of gold. The properties include 13 former mines, deposits and resource target areas, all within a 60 km radius of its Copper Rand mill.
The revised operating plans for 2016 for the South America copper mines principally reflect adjustments to the mine plan at El Abra (which produced 367 million lb in 2014) to reduce mining and stacking rates by about 50% to achieve lower operating and labor costs, defer capital expenditure and extend the life of the existing operations.
