Coloso has tested 64-67% in presumed center and some outcroppings have been 67%-not sure of def of Grade A ore-there are 2 benchmarks for ore-58% and 62%-China's average domestic ore is down to 20%-and China is mining as low as 4% ore (PBS documentary) in underground mines-thus agmetalminer said 12-13-10 (when China's average was 30%) that China's domestic ore cost averaged 150/ton and that thus 150/ton would be floor for iron prices-until a new speculative derivatives market for iron let specualtors loose to do their thing ca Labor day 2011-and ore prices have been recovering since October-as China continues to run out of economically produced ore I postulate this would be an upward pressure on prices longterm-especially w Australia instituting heavy export taxes of over 30% and India doing the same-India doesnt want to be in the same baot as China in next 20 years.
