Summary:
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.

Summary:
(Translated from Spanish by Google Translate)
The Islay mine, with a production capacity of 450 tpd, is part of The Chungar unit. Mined ore is processed 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.
During 2021, the operation was focused on the Sur, Sur Techo and Islay Piso structure veins and the Jazmín layer. The pumping system infrastructure inside the mine began with a total capacity of 400 l/s.
In 2022, the operation was centralized in the structures vein South, Islay Piso, and Guadalupe mantle. Ore production was up 6% from 2021, zinc and silver fines production results increased by 4% and 3%, respectively, while lead and copper fines production decreased by 0.3% and 1% respectively. A fourth line was implemented in the pumping system infrastructure inside the mine for a total capacity of 420 l/s, which guarantees the development of the deepening of the mine. In addition, 3 mining shelters were implemented for emergency response. The main ventilation circuit was sealed, changing from sleeve/board plugs to block plugs, improving coverage from 96% to 112%.
