Both deposit types are linked to magma carrying metals and ligands that rises to form an upper-crustal magma chamber. Magma convection and fractionation lead to volatile exsolution and collection in the apical parts of the chamber, from which exsolved hydrothermal fluid ascends to form either a porphyry Cu-Au deposit associated with stocks and dykes generally at 2-5 km depth, or an epithermal deposit associated with coeval volcanic rocks at depths of <1 km.
