Nov 23, 2010 (A Pace) - The property is underlain dominantly by intermediate to mafic metavolcanics rocks which strike east-west and dip vertically. The property shows a well developed vertical foliation trending 110 degrees with local variations due to cross-structures. Based on work done, it is considered that there is one broad zone of deformation and strong carbonate alteration trending east-west across the central part of the property. Associated with the defomration zones are banded iron formations considered to be favourable to hold gold mineralization. The magnetometer survey indicated that the majority of the property shows relatively high magnetics. This may suggest the area is underlain by metavolcanic units trending approximately east-west and underlain or intruded by an ultramafic flow or sill.

Nov 23, 2010 (A Pace) - A prospecting survey indicated a large shear zone running southeast that is strongly sericitized and carbonated and that carries quartz veins and disseminated pyrite. The shear zone is located in mafic volcanics and is one of the areas where sampling was completed. A total of eight samples were collected. The best assay result is from sample 1236 at 0.045 oz/t Au. This is from the quartz vein. Conductive zones have been identified and are considered to be parallel to the formational contacts that may be due to sulphides. Most of the conductive zone show a magnetic signature which is considered to be a large valid target for more exploration.
