gross profit, page-4

I'd chime in that 90,000 tonnes is not going to provide $630m gross profit. At the very best it would provide $630m of revenue. You would then have to take costs off before you got near gross profit.
Then as Hoots explained, this is CuEq, not copper, so without rail, something they don't have permission to build, the magnetite isn't going anywhere, and if the cobalt is a 1% (I thought I read something lower) concentrate in pyrite, it isn't going anywhere either until the rail facility is operational.
So the number will be a little less than $630m.
