The Pucarrajo mine is an underground polymetallic mine which had been in operation for more than 30 years.
The Pucarrajo mine was put on care and maintenance by its previous owner in 2008 due to weak metal prices. Since its acquisition by Nyrstar in July 2010, no exploration and development work has been carried out by Nyrstar and in April 2014, the Group identified the mine as a non-core asset. The mine has not produced and remains on care and maintenance. Nyrstar has decided to close the Pucarrajo mine, a process that is expected to take up to 10 years at an estimated cost of US$ 18 million. |

Summary:
The Pucarrajo underground multi-metallic mine, with more than 30 years operating history, is located in the Central Peruvian Andes, 425km north-east of Lima, Peru, close to several producing mines. At Pucarrajo, skarn mineralisation is hosted in preferred lenses within folded limestone sequences close to granodiorite and diorite intrusions. Minor compressional faulting has subsequently offset (>1m) bedding and mineralisation.
