Or another way of looking at it...

Mine haulage is ~$0.15/tkm (measured one way inclusive of road maintenance, fuel etc). As there is limited maintenance (either end of the haul only, not on the bitumen) it's a conservative number.

Say 150km one way
$22.50/t
Say 3g/t recovered (3.16g/t at 95% recovered) = $7.50/g = $233/oz

So low grade is unlikely to be trucked, as 1.5g/t material will cost >$450/oz just on trucking.
