Dec 07, 2005 (K R Kettles) - The property is principally underlain by altered mafic metavolcanic flows. The units strike at approximately 100 degs and dip steeply south. On the basis of pillow packing, stratigraphic tops are to the south. The mafic flows have locally been highly sheared, and foliation is parallel to stratigraphy. Thin iron formation units are intercalated within the mafic flows. Thin, discontinuous quartz porphyry dikes have been observed on the property.

Dec 07, 2005 (K R Kettles) - A zone of sheared and altered mafic metavolcanics has been traced for a distance of about 460.0 m. The zone strikes E-W. Thin carbonate and quartz-carbonate stringers are common in the zone. Scattered, erratic gold values have been obtained from the sheared mafic metavolcanics in the zone. Narrow sections of drill core from three drill holes returned the following high assays: 3.86 opt Au/0.27 m, 0.42 opt/0.92, 0.18 opt/3.05 m (sludge sample).
Dec 07, 2005 (K R Kettles) - The mafic metavolcanics have been silicified and carbonatized.
