SnapshotYanacocha consists of the following open pit mines: the La Quinua Complex, the Yanacocha Complex, the Carachugo Complex, and Maqui Maqui. Yanacocha has four leach pads, with leaching operations at La Quinua and Carachugo.

Yanacocha also has three gold processing plants (Pampa Larga, Yanacocha Norte and La Quinua), one limestone processing facility, and one mill (Yanacocha Gold Mill).

The La Quinua Complex finished mining in 2021. The Yanacocha Complex has had limited mining operations in recent years. The Maqui Maqui operations mined material from multiple mines that are no longer in operation. The Yanacocha Gold Mill ceased operations in February 2021 and has been placed into care and maintenance. The Carachugo leach pad processes oxide material from Quecher Main.

The Yanacocha Sulfides project will develop the first phase of sulfide deposits and an integrated processing circuit, extending operations beyond 2040 with the potential to extend life for multiple decades.

Deposit type

  • Epithermal
  • Volcanic hosted

Summary:

Yanacocha is an epithermal type deposit of high sulfidation hosted in volcanic rock formations. Gold is associated with ironoxides and pyrite.

The Yanacocha gold district is a 10x4km zone of altered rocks within a belt of tertiary volcanics that extends the whole length of Peru. Andesitic domes and dome complexes have been silicified and leached by epithermal gold-bearing solutions in at least nine distinct deposits. The mineralised sequences, which can also contain significant amounts of silver, are flanked by extensive argillitic alteration, and subsequent events have created siliceous breccia pipes with localised high gold grades.
