Project Overview
The Neves-Corvo copper-zinc-lead-silver mine is situated approximately 220 kilometres southeast of Lisbon in the Alentejo district of southern Portugal. The mine access are provided by one vertical five metre diameter shaft and a ramp from surface. The mine is highly mechanized and a number of different stoping methods are employed but the most significant are bench-and-fill and drift-and-fill. The treatment facility at Neves-Corvo comprises of two processing plants. The copper plant treats copper ores and has a maximum capacity of approximately 2.8 Mtpa and the zinc plant, which treats zinc or copper ores was recently expanded to a capacity of 2.5 Mtpa.
Neves-Corvo is located in the western part of the Iberian Pyrite Belt, which stretches through southern Spain into Portugal. The mineral deposits at Neves-Corvo are classified as volcano-sedimentary massive sulphide. They typically occur as lenses of polymetallic (copper, zinc, tin, lead) massive sulphides that formed at or near the seafloor in submarine volcanic environments. Seven massive sulphide lenses have been defined comprising Neves, Corvo, Graça, Zambujal, Lombador, Semblana and Monte Branco. The massive sulphide deposits are typically underlain by stockwork sulphide zones, which form an important part of the copper orebodies.
