Abstract Using archived samples, two comprehensive vertical profiles in the central part of the Chuquicamata open pit have been studied. The observed textures and mineralogy suggest, at the preliminary stage of the study,that digenite and sphalerite might be predominantly or entirely hypogene. Covellite and chalcocite can be both hypogene and supergene, but textural analysis allows a discrimination in certain cases.
