Structural Geology

The alteration system has been interpreted to be cored by an unroofed pluton of probable Cretaceous age. The emplacement of the postulated intrusion has resulted in the apparent doming and uplift of the Shamrock area which has been referred to as the Ketza Uplift. Mapping on the property indicates that there are five deformation events affecting the rocks in the area. The gold mineralized stock work veins and disseminated replacement mineralization preferentially occurs within central zones of S2 anticlines in proximity to D4 faults. The faults acted as conduits for the mineralizing solutions which feed fracture joints associated with the anticlinal structures. The steeply dipping normal faults that developed around the Ketza Uplift are the conduit structures for the mineralization. Bedding dip measurements indicate that the folds are east-west trending with moderately north-northeast dipping axial planes. The cross cutting normal faults are an important locus for high grade gold zones which can be expected in areas proximal to a possible unexposed intrusion at the core of the Ketza Uplift.
