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.

Animon Mine in Peru's Huaron mining district is hydrothermal polymetallic deposit (hosting silver, lead, zinc, and copper) consisting of mineralized structures probably related to Miocene aged monzonite dykes principally within, but not confined to the Huaron anticline. Mineralization is encountered in veins parallel to the main fault systems, in replacement bodies associated with the calcareous sections of the conglomerates and other favourable stratigraphic horizons, and as dissemination in the monzonitic intrusions at vein intersections.  

Mineralization occurs mainly in veins but also in “mantos” (stratiform deposits) and replacement deposits. Mineralized veins vary from a few centimetres to up to 10 metres wide, and may extend along strike for up to 1,800 metres. Most of the structures show open mineralization at depth and have excellent exploration potential.
  
The first pulse of mineralization was associated with the emplacement of intrusive bodies and the subsequent opening of structures, during which zinc, iron, tin, and tungsten minerals were deposited. This was followed by a copper, lead, and silver rich stage, and finally by an antimony/silver phase associated with quartz.

In 2015, production at the Animón mine leveled out at 4,000 tpd, and long-hole drilling methods were implemented for the purpose of efficiently exploiting narrow ore veins.

In 2015, Islay Mine consolidated its production levels at 1,800 tpd. 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.

In 2015, 94% of the mineral extracted at the Chungar unit was processed at the Animón plant, while 6% was processed at the San Expedito plant, part of the Cerro de Pasco unit.

The 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.
