The mineralization in Islay comprises a breccia-type fissure fill, mainly with silver mineralization, with subordinated lead and zinc, Animon is a hydrothermal polymetallic deposit consisting of mineralized structures probably related to Miocene aged monzonite dykes principally within, but not confined to the Huaron anticline.

Islay is located 5 km to the West of Animón. It correlates as a western extension of the Animón veins, with the same geologic characteristics. The average width of the Islay vein is around 4.00 metres, it outcrops at surface and was exploited in small open pits. At the moment, it is being prepared for its next stage as an underground operation. Diamond-drilling has determined an average resource grade of 0.1%Cu, 1.0%Pb, 1.4%Zn and 8.7oz Ag/mt.
