Mar 30, 2012 (A Wilson) - Four vein systems were mapped and only two were sampled. These two veins are 500 feet apart, in Mississagi sediments. The north showing consists of parallel quartz - chalcopyrite veins striking NW, that have been traced for a length of 1000 feet. They range in width from a few inches to 3 feet. The south showing consists of a 4 foot quartz - chalcopyrite vein, striking west which has been traced for a length of 25 feet.
