Grade of Strike at CheechooDoes any one have an educated guess on the average grade on Cheechoo Im guessing .55 g/ton gold and 350 million tons.Thats close 5.2 million oz gold.. Why I say this is thhe strike size 1600 x 700 x 650 thats 1.8 billion tons of rock if we take 18% of the strike we get close to that number.5 million oz gold.at a grade of .55 g/ton .
