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.

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. 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.

Animon is a part of Changar mining unit that is located at 4,600 m.a.s.l. in the region of Pasco, 219 km east of Lima and comprises of two underground mines: Animón and Islay; and a concentration plant named Animón.

Islay uses the mining methods of Sub-level stoping for the veins and room and pillars for the bodies.

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. [2014, AR, p.58]

The Animón plant decreased its treatment tonnage by 30% compared to the previous year, due to the stoppage of operations in March due to the state of emergency. Operations were restarted as of May 2020, with an increase in the tonnage processed progressively during June and July.
