![]() Gold bearing copper deposits constitute an important part of Chile’s total gold production. Low-sulfidation epithermal, IOCG and mesothermal type appears as less relevant. After analysing 82 cases in total, main gold concentration can be assigned to high-sulfidation epithermal and porphyry type deposits. ![]() Due to its relationship with episodic magmatism migrating eastward, there is a tendency for the deposits to be in distinct, north-south trending, belts with a progressive west to east decrease in mineralization age. These hydrothermal ore deposits are genetically associated with subduction related Andean arc magmatism. ![]() ![]() Mesozoic deposits are common but less relevant regarding their size and gold content. A review of gold and gold bearing base metals deposits in Chile, indicate the existence of at least six different type of ore deposits, most largely formed during the Cenozoic with predominance in the Miocene. ![]()
