Chile’s Mining Sector Advances Copper Production Expansion

Chile’s mining investment landscape includes the Sierra Gorda copper mine expansion, valued at approximately US$725 million and announced by KGHM on 2 October 2026. The project involves a fourth grinding line intended to increase ore-processing capacity from around 48 million to 60 million tonnes annually. Environmental consultants, mining suppliers and sustainability specialists can explore opportunities in water management, energy efficiency and environmental monitoring. The US$725 million figure is the overall mine-expansion investment, not a separate environmental-services contract.
