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.
Summary:
Pucarrajo is a mine with reserves of zinc, lead and silver located in the province of Bolognesi, Ancash region. All three of Nyrstar Peruvian Operations are using Flotation Circuit.
