  abstract = {{T}he {J}ulie deposit is currently the largest gold prospect in {NW} {G}hana. {I}t is hosted in sheared granitoids of {TTG} composition of the {P}aleoproterozoic {J}ulie greenstone belt. {T}he main mineralization consists of a corridor of gold-bearing quartz veins forming a network of a few tens of metres in thickness, trending {E}-{W} and dipping 30-60 degrees {N}, contained within the main shear zone that affects these rocks. {T}he core of this vein corridor is altered by sericite, quartz, ankerite, calcite, tourmaline and pyrite, and is surrounded by an outer halo consisting of albite, sericite, calcite, chlorite, pyrite and rutile. {A}second set of veins, conjugate to the first set, occurs in the area. {T}hese veins have alteration halos with a similar mineralogy as the main corridor, however, their extent, as well as the size of the mineralization, is less important. {I}n the main corridor, gold forms micron-sized grains that occur in pyrite as inclusions, on its edges, and in fractures crosscutting it. {S}ilver, tellurium, bismuth, copper and lead commonly accompany the gold. {P}yrite occurs disseminated in the veins and in the surrounding rocks. {U}p to several ppm {A}u occurs in the structure of pyrite from the main mineralization.},
