Coricancha mine

Coricancha mine

The Coricancha mine is an underground poly-metallic mine with more than 60 years of operating history, which comprises a 600-tonne per day ore processing facility, underground mine and reserves and resources containing gold, silver, zinc, lead and copper.

The mine has three main product streams, comprising gold/silver dore, zinc concentrate (suitable for treatment at Nyrstar’s European and Hobart smelters) and lead concentrate high in precious metals (suitable for treatment at Nyrstar’s Port Pirie smelter). The Coricancha mine is managed in conjunction with the Contonga and Pucarrajo mines by a single experienced management team, utilizing the shared services of Nyrstar’s Lima office. The Coricancha mine is located (approximately) 90 kilometres east of Lima, Peru in close proximity to a number of other significant mining operations and exploration properties.

Mine Planing

Hatch Ltd.

Hatch has been retained by Nyrstar Ltd to provide its subsidiary, Compañía Minera San Juan (CMSJ) Peru, with short term mine planning, a year of scheduling, and a review of the Coricancha mining operation in San Mateo, Peru.

The Coricancha project includes two underground polymetallic mines, a concentrator and bioleaching plant, and tailings dam facilities; located between 3,000 and 4,500 metres above sea level in the Andes.

In an earlier assignment, Hatch’s operational-readiness study highlighted areas of concern at the mine. Nyrstar then requested Hatch’s assistance with short term planning and scheduling to solve bottlenecks in the ore supply. Improvements in ore supply will lead to a lower cost per tonne. The Hatch offices in Peru and Australia managed the assignment, which was completed in July. Nyrstar has also awarded Hatch the long term mine planning assignment, which aims to increase the mine’s life and overall project value.
