Project at Aljustrel
Ore Systems Consulting, as of November 1998, has commenced a series
of studies on stratigraphic and alteration relations at the Feitais
and Moinho VMS deposits on the Aljustrel property in southern
Portugal, for EuroZinc Mining Corportation of Vancouver. These
deposits, together with three others on the Aljustrel property,
are hosted a dominantly rhyolitic sequence of Devono-Carboniferous
age which lies within the northwestern portion of the Iberian
Pyrite Belt.
The Aljustrel deposits contain over 150 Mt of massive sulfides
in total, of which the Feitais deposit contains at least 55 Mt
(it is still open in some directions). Other massive sulfide deposits
within the Iberian Pyrite Belt include the world-class Neves Corvo
deposit, located some 50 km to the south of Aljustrel, and the
Rio Tinto, Tharsis and Aznalcollar deposits in Spain.
