  abstract = {{T}he {B}epkong gold deposit is located in the {W}a-{L}awra belt of the {P}aleoproterozoic {B}aoule-{M}ossi domain of the {W}est {A}frican {C}raton, in {NW} {G}hana. {I}t occurs in pelitic and volcano-sedimentary rocks, metamorphosed to greenschist facies, in genetic association with zones of shear interpreted to form during the regional {D}-3 deformational event, denominated {D}-{B}1 at the deposit scale. {T}he ore zone forms a corridor-like body composed of multiple quartz +/- carbonate veins surrounded by an alteration envelope, characterized by the presence of chlorite, calcite, sericite, quartz and disseminated pyrite, arsenopyrite plus subordinate pyrrhotite and chalcopyrite. {T}he veins contain only small proportions of pyrite, whereas most of the sulphides, particularly arsenopyrite, occur in the altered host rock, next to the veins. {P}yrite is also common outside of the ore zone. {G}old is found in arsenopyrite, where it occurs as invisible gold and as visible - albeit micron-size - grains in its rims, and as free gold within fractures cross -cutting this sulphide. {M}ore rarely, free gold also occurs in the veins, in fractured quartz. {I}n the ore zone, pyrite formseuhedral crystals surrounding arsenopyrite, but does not contain gold, suggesting that it formed at a late stage, from a gold-free hydrothermal fluid.},
