Fluor Corp. said it has received full notice to proceed under its engineering, procurement and construction management contract with Sierra Gorda Sociedad Contractual Minera for the Fourth Grinding Line Expansion Project in Chile.
Located approximately 60 km south of Calama in Chile’s Antofagasta Region, Sierra Gorda is a large-scale open-pit copper-molybdenum mine. The brownfield expansion will add a fourth process line, including a new primary crusher, a high-pressure grinding roll crusher, fine ore grinding, flotation and associated support facilities. The project is designed to increase the concentrator’s ore-processing capacity from approximately 130,000 metric tons per day (mt/d) to 165,000 mt/d.
“Having supported the original development, we are pleased to bring our knowledge of the operation and global project delivery expertise to this next phase of growth,” said Harish Jammula, president of Fluor’s Mining & Metals business. “We look forward to safely delivering a reliable, capital-efficient solution for our client.”
Construction activities are expected to start in 2027.
