Sep 15, 2015 (A Wilson) - A zone of magnetite about 15 ft wide was exposed in the pit. The shipment of ore assayed 47.2% total iron, 44.5% acid soluble iron and 11.21% TiO2. An ilmenite concentrate assaying 35.65% TiO2 was obtained by gravity concentration if -65 M tailing. The recovery of TiO2 was 62.3%
