Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The area underlying the occurrence is comprised of mafic and ultramafic variolitic and pillowed flows. Stratigraphic tops are to the northwest. Foliation is parallel to subparallel to bedding. DEPOSIT DESPCRIPTION: The highest gold values appear to be located in northeasterly striking shear zones in which the mafic and ultramafic rocks are altered to chlorite and talc schists respectively. The highly sheared volcanic rocks have also been carbonatized and contain quartz stringers.
