Antofagasta Receives Go-ahead for Centinela Expansion On December 12, Antofagasta Minerals received approval from environmental regulators of a proposed expansion of its Centinela mine in northern Chile. The project will cost around $4.35 billion and will be done in two stages to increase copper production and extend the life of the mine until 2056. The expansion could include building a second concentrator plant, two new pits and a deposit for additional thickened tailings, among other things, the com- pany said. The initiative will also double its cop- per production, increasing it to more than 400,000 metric tons of copper per year over the next decade. "With environmental approval, we will be completing the engineering studies in the coming months," Antofagasta Chief Executive Ivan Arriagada said in a state- ment. "We hope to submit this project to the board of Antofagasta in 2018 once these studies are done."

The Mupani mine will employ approx- imately 1,000 people at full production, as well as a substantial number of con- tractors during development, construc- tion, and commissioning of the project. The mine design builds on the modern, low-cost, mechanized room-and-pillar mining method that is employed at Zim- plats' current mining operations. Once commissioned, Mupani ore will be beneficiated at the existing Ngezi/ Selous processing facilities and smelted in the 12.5-megawatt (MW) Zimplats fur- nace, which was recently equipped with modern remote-controlled hydraulic mud guns for safe furnace tapping and upgrad- ed furnace automation for online condi- tion monitoring and safe process control. Zimplats produced 290,400 oz of platinum in its fiscal year to June 30, 269,500 oz in converter matte and 20,900 oz in concentrate sold. (Regional News-Africa - from p. 12)
