Correct me if im wrong..
5000 tonne per month cost of production is 5000 X $54 = 270K
Payment at a grade of CU 4.5% ..5000 X $137.77 = $688,850 profit is $418,850
Payment at CU grade of 7.5% ... 5000 X $329 = $1,645,000profit of $1,375,000
Im probably missing something this sounds too good to be true, all depends on CU grades i spose..
