Heavy and widespread sulphide mineralization was encountered over the majority of the lengths of all four holes, with sections of massive to semi-massive sulphide concentrations present along with stringer zones in intimate association with heavy amphibole alteration. From visual inspection it appears that the holes intersected the same mineralized system consisting of upper amphibolite-metamorphosed mafic and felsic gneiss that have suffered intense pre-metamorphic, volcanogenic massive sulphide style (“VMS”) hydrothermal alteration which strongly metasomatized the rocks, in some cases transforming them locally to massive actinolite. The system is clearly large and anomalous with regard to the amount of sulphides present and in base metal and arsenic content. In the context of a VMS interpretation, El Gordo is quite a large target and only a small part has been tested to date.
