At higher levels, copper mineralization becomes dominant with the deposition of a mesothermal assemblage including chalcopyrite, chalcocite, chlorite, fluorite, and sphalerite. At higher levels again, there is a gradual change to an epithermal suite with the deposition of galena, stibnite, haematite, and siderite. Mining Methods Sublevel stoping
