Trois étapes sont courantes: la première (étape à haute température) se caractérise par la formation d'or et d'argent natifs associés à des minéraux sulfurés primaires tels que la pyrite, la galène, la cassitérite, la litharge et l'arsénopyrite. La deuxième étape (à température plus basse) est caractérisée par la formation de minéraux sulfatés secondaires. La troisième étape est liée à la calcification formée après l'oxyde (altération supergène) et caractérisée par la formation de calcite et de minéraux d'uranium.
