Yanacocha is a medium-sized mine, and is the second largest gold producer in Peru.
The Yanacocha Complex mined material from the Yanacocha Layback and Yanacocha Pinos, which has had limited mining operations in recent years, finished mining operations in 2022. The Maqui Maqui operations mined material from multiple mines that are no longer in operation. The Yanacocha Gold Mill ceased current operations in February 2021 and has been placed into care and maintenance. It will be repurposed for use as part of the Yanacocha Sulfides project. The Carachugo leach pad processes oxide material from Quecher Main, which is a new open pit within the existing footprint of Yanacocha. This project went into commercial production in October 2019
In the second quarter of 2023, the Company announced the deferral of the full-funds investment decision for the Yanacocha Sulfides project in Peru for at least two years, currently estimated to occur in 2026. |

- 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.
Summary:
The Yanacocha property began production in 1993 and consists of the following open pit mines: the La Quinua Complex, the Yanacocha Complex, the Carachugo Complex and Maqui Maqui.
The La Quinua Complex mined material from the La Quinua Sur and the Tapado Oeste Layback and finished mining operations in 2021.
The Yanacocha Complex mined material from the Yanacocha Layback and Yanacocha Pinos, which has had limited mining operations in recent years, finished mining operations in 2022.
The Maqui Maqui operations mined material from multiple mines that are no longer in operation.
The Carachugo leach pad processes oxide material from the Quecher Main project, which is a new open pit within the existing footprint of Yanacocha. This project went into commercial production in October 2019 and will extend the life of the Yanacocha operation to 2027.
Yanacocha’s available mining fleet consists of two shovels, four excavators, and 25 haul trucks, each with 233-tonne payload.
