Zaldívar Submits Tailings Dam Expansion Environmental Impact Assessment

Zaldívar, in which Antofagasta plc recently bought a 50% stake from Barrick Gold, has submitted an environmental impact assessment (EIA) for the expansion of the useful life of two tailings dams at the mine. The project involves increasing the height of the tailings dam wall from 3,091m above sea level to 3,099m above sea level, which will increase capacity by 5.7Mm3, according to documents filed with the environmental evaluation service (SEA) in Antofagasta region (II). The expansion of the tailings dam will allow the company to maintain operational continuity at Zaldívar through 2023. The company noted that the project does not involve increasing the mineral extraction rate at the mine, and therefore doesn't entail a growth in water consumption. Additional work includes construction of a canal around the perimeter to separate the stormwater from the tailings, the extension of a power line and a safety dump site. Planned investment for the project is set at USD 40 million, according to the EIA. If approved, work is scheduled to start in October 2016 and take one year to complete.
