 The basis of the current structural work at the Galena is that the emplacement of the vein arrays is structurally controlled.There are secondary controls imposed by stratigraphy and geochemistry but structure is considered the most dominant because the movement of fluid required for vein and mineral precipitation requires the presence of active structures.A geometric model of the Coeur-Galena was constructed in Datamine Studio software, which has allowed for examination of the faults and veins and their relationships to one another.
