Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The oourrence is located west of the Dome Stock and is underlain primarily by altered mafic volcanic rocks. These are composed of tuffs and flows. Pillow structures have been found that indicated the flow tops are to the northwest. Volcanic breccias have also been recognized in the area. Intruding into the volcanics are gabbroic to dioritic dikes. Foliation planes in the volcanic rocks strike approximately NW-SE and dip vertically. Several wide sulphide rich zones have been observed, which contain pyrite, pyrrhotite and chalcopyrite. DEPOSIT DESCRIPTION: A wide shear zone is located on the western end of the island, and it is believed to be the locus for the gold and silver mineralization. Several 3 to 5 cm quartz veins and numerous quartz-carbonate stringers have been noted from drill core. GEOPHYSICAL DATA: A strong EM conductor with good width was discovered and this probably represents a zone of sulphide mineralization.
