Low-sulphidation epithermal systems are mineralized environments typically found in volcanic arcs, where hydrothermal fluids circulate near the Earth's surface, depositing minerals in cracks and cavities. These systems are characterized by low temperatures and low sulphide content, making them an ideal host for high-grade gold deposits. The gold in these systems is often associated with quartz veins, where it precipitates alongside other minerals such as silver, calcite, and adularia. The unique conditions of low-sulphidation epithermal systems—such as their shallow depth, hydrothermal fluids, and favorable geological settings—make them significant exploration targets for gold, with many world-class gold deposits being discovered within these systems.
