Located in the Huaron mining district, Chungar encompasses the Islay and Animon mines. 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.

The Chungar unit has two underground mines: the Animón mine, with a production capacity of 3,200 tpd and the Islay mine with a production capacity of 450 tpd, the tonnages produced by these two mines are treated at the Animón plant.

The mining method at Islay is sub-level stoping in vein-hosted mineralisation, and room and pillar for sub-horizontal mineralized bodies.

The operation of the infrastructure of the pumping system inside the mine began for a total capacity of 400 l/s, which guarantees the development of the deepening from the mine On the other hand, the operation was centralized in the Veta Sur, Sur Ceiling, Islay Floor and the Jasmine mantle.

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.

The Animón concentrator plant achieved better recoveries in zinc of 92.0%, lead of 92.0%, copper of 65.6% and silver of 84.3% versus 2020. The Silver recovery is due to better head grades for both lead and silver, as well as optimization of the metallurgical process with the reconversion of a balls to one of the bars.

In 2021 Silver recovery is due to better head grades for both lead and silver, as well as optimization of the metallurgical process with the conversi ........
