Yauli

The Yauli unit is located between altitudes of 4,000 and 4,900 m.a.s.l. in the region of Junin, 40 km from the city of La Oroya and 170 km from Lima. The unit is made up of four underground mines and an open pit, whose mineral is treated in three concentration plants, with an installed capacity of 11,400 TPD.

This region shows mineralization related to polymetallic epithermal systems, replacement bodies and polymetallic vein systems, as well as porphyry mineralization and skarns, thus indicating the great potential of the area.
