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.
Mining Methods
- Sub-level stoping
- Room-and-pillar
Summary:
(Translated from Spanish by Google Translate)
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.
