Dec 04, 2009 (A Wilson) - The No 1 Central area has been determined to have 80,000 tons per vertical foot of 20.5% soluble iron. Tests show that 23,000 tons per vertical foot can be recovered by magnetic concentrate grading 65.19% soluble iron. Area No. 1 North has a calculated average grade o 16.39% Fe over 165 feet of core. The iron formation assayed an average grade of 22.08%; 26,000 tons per vertical foot was indicated by mapping and geophysical survey. The 1978-79 Canadian Mines Handbook reports ore reserves were over 50,000,000 tons averaging 21% soluble iron, sufficient to produce 1,000,000 tons of concentrate for 15 years.
