Over the past 15 years, exploration activity for PGE in the Iberian Peninsula has led to the discovery of two PGE occurrences of very different types -- the Aguablanca Ni-Cu-PGE suiphide deposit [3,4,5] and the Cabo Ortegal PGE-bearing chromitites [6,7] Of most interest is Aguablanca which, in contrast to the low tonnage-high grade Cabo Ortegal mineralisation, has both economic and strategic potential.
