| ABSTRACT: | Hargraves is a structurally controlled, mesothermal gold system, hosted within the midSilurian to mid-Devonian Hill End Trough of the Palaeozoic Lachlan Fold Belt. Local geology comprised a thick sequence of turbidites and volcaniclastics which were subjected to multiphase deformation and metamorphism, resulting in a series of north-south trending anticlines and synclines. Gold mineralisation is hosted within quartz saddle reefs, cleavage-parallel veins and steeply west dipping fault zones within the axial region of the locally dominant Big Nugget Hill anticline. Mineralisation association with quartz veining was confirmed; however, multiple phases of quartz occur and not all were mineralised. Narrow, low-displacement faults, striking parallel to the axis of the anticline and westerlydipping, are referred to as feeder structures and may represent former conduits | |
