Dec 07, 2005 (K R Kettles) - The northern half of the property is primarily underlain by mafic metavolcanic flows. The flows strike approximately 120 degs and dip steeply to the southwest. Thin lenses of iron formation are intercalated with the flows. The northern half of the property is underlain by a sequence of clastic and chemical metasediments. Stratigraphic tops are to the SW. Gold mineralization is hosted by the iron formation.

Dec 07, 2005 (K R Kettles) - Gold occurs in thin arsenopyrite bearing quartz-carbonate veins up to 15 cm wide in banded chert-magnetite iron formation. A grab sample taken from one of the trenches returned an assay of 0.07 opt Au and 3.0% As.
Dec 07, 2005 (K R Kettles) - The mafic metavolcanic flows and iron formation units have been silicified and carbonatized.
