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. Additionally, one drillhole shows an increase in lead and zinc at 150 metres depth.

The mineralization in ISLAY comprises a breccia-type fissure fill, mainly with silver mineralization, with subordinated lead and zinc, in associated with calcite, rhodocrosite, silica and rhodonite.

A mine development and preparation program was executed that will make it possible to maintain mining tonnage levels thanks to long-hole drilling methods and cut-and-fill breasting methods.

It began with the construction of the infrastructure of the pumping system inside the mine for a total capacity of 420 l / s, which will guarantee the development of the deepening and lateral development of the mine.

The Animón concentrate plant processed 5,500 tpd of polymetallic ore using selective differential flotation. In 2014, measures taken to increase metallurgical recovery included installation of an automatic lime dosing system, placement of a third flash cell in the lead-silver circuit and modification of the rotation speed in lead and zinc flotation cells.

The flotation processes are controlled using real-time information provided by the SCADA analysis system.
