StandardDetailedBy ChemistryMineral Photos (25)Site Photos (1)Search Google

A volcanic-hosted massive sulfide (VHMS) deposit of the Iberian pyrite belt, which consists of five orebodies (Corvo, Graça, Neves, Lombador and Zambujal).
The copper-zinc-silver mine started 1984. Was to have produced 1 million tons/year ore by 1987. Owned by RTZ (49%) & Somincor. This is one of the most gigantic deposits of massive sulphides in the world.
