San Julian is a gold, silver, lead, zinc underground mine. The San Julian mine, operated by Fresnillo PLC, has been developed in two main phases due to its different ore types, the silver-gold veins, and the disseminated ore bodies. Each of these mineralization kinds requires different mining methods and processing facilities to efficiently extract minerals.
