RE:Fortune's Fortune?Diamond mines have very little in common with Nico. You shouold compare concentrating costs with other base metal operations, like Teck in Alaska, Constatine's Palmer deposit, any of the Eskay Creek developments, Canarc's New Polaris Mine or others like this. You'll see costs for example, processing at Palmer at $16.83 per tonne. It's cheap and proven. and $24.25 per tonne at Eskay Creek.
