Golden Pig mine is in the central part of the Southern Cross greenstone belt within the Archaean Yilgarn craton. The mine has produced approximately 2.5 Mt of ore at 5.7 g/t Au to yield approximately 450 000 oz. The majority of gold mineralisation is hosted within extensively deformed and quartz-veined BIF's. In addition to the BIF-hosted mineralisation, an increasingly important part of the resource lies in the Taurus Lode, which is a N-NNW-trending amphibolite facies shear zone. The Taurus Lode lies within a continuous shear-zone that has a moderate to steeply WSW dipping foliation, and a mineral lineation of biotite, amphibole and pyrrhotite plunging consistently 10 S. Drive faces, subperpendicular to the foliation and lineation, consistently show evidence for syn-mineralisation reverse shear. Exposures parallel to the mineral lineation and perpendicular to the foliation reveal both sinistral and dextral asymmetries. These characteristics suggest that the vorticity axis of the Taurus Shear Zone is parallel to the mineral lineation, and that the simple shear sense is reverse. This geometry can arise when there is a major component of flattening across the shear zone, which may be due to interference between two adjacent granite domes. The BIF-hosted lodes plunge consistently 15 NNW coincident with the intersection of the axial planar cleavage of the regional folds and the Taurus Shear Zone. However, where the penetrative shear characteristics control the orientation and geometry of the mineralisation, oreshoots plunge SSW, parallel to the stretching and mineral lineations within the shear. The SSW plunge of strike extensive and laterally confined high-grade, economic ore shoots within the Taurus shear is fundamental to defining the economic mineralisation within this lode. Identifying the zones of maximum continuity and establishing the optimal position for future development will maximise ore extraction.
