South America: Cerro Lindo, Peru

SRK was commissioned by Minera Milpo S.A.A. (Nexa Resources) to prepare an environmental study for the expansion of the processing plant to 22.5 Ktpd. The study included technical improvements of processing systems and ancillary facilities, and modifications to the desalination plant. The impacts associated with the proposed activities were identified and assessed. Occupation of new areas and dust emission due to ore transport were determined as the critical impacts. Two irrigation systems were recommended as an environmental mitigation measure; 90% of the water use would be recirculated.
