Figure 1. Location of Aljustrel, Portugal, and other VMS deposits of the Iberian Pyrite Belt. Most of the deposits consist of Zn-bearing massive pyrite bodies with Cu-rich lower portions; Au and Ag are also recovered. The Neves Corvo deposit, some 40 km southeast of Aljustrel, is unusual in containing a large zone of Cu-rich ore and a small zone of Sn-rich ore.
