Gold Mineralization

The gold mineralization occurs with sulphide in quartz breccia veins, vein stock work, and disseminated in silicified sericite altered sedimentary and carbonate-bearing rocks. Thick massive quartz breccia veins of up to 30 metres containing abundant sulphide mineralization and scorodite that in-fill steeply faults routinely grade from 0.50 to 2.5 g/t gold and represent probable feeder veins to stockwork and disseminated gold zones. The gold bearing quartz-sulphide vein stock work is composed of anastomosing veins and stringers cross cutting phyllite or angular breccia infilling veinlets in massive quartzite beds. The stock work type of mineralization commonly overlaps the two rock types near the lithological contact with average grades of approximately 1.0 - 5.0 g/t gold. Silicification occurs with the quartz stock work veins in all rock types (including calcareous siltstone and limestone) with average grades of 0.5 to 1.5 g/t gold.

The gold mineralization in the Shamrock area has been partially drill tested along a 1200 metre length over a 500 metre width and through a 500 metre vertical interval. The gold in soil geochemical anomaly fringes the ridge top in the centre of the Ketza uplift and has an extensive down slope dispersion in the soils and talus. See figure 2. Mapping indicates cross cutting quartz-sulphide veins, scorodite rich shear zones and thick massive beds mineralized with stockwork veins and disseminated sulphide outcropping in the cliffs and slopes above the soil anomaly. The drilling has attempted to follow an apparent structural tend and stay within the bounds of the mineralized system using large step out drill holes. The drill holes have intersected a series of semi-continuous steeply dipping quartz breccia veins along a trend striking at approximately 330o. The projection of the veins and accompanying alteration may be associated with a number of other gold occurrences over a distance of four kilometres to the northwest.
