I think your calcs are wrong.

Mining & processing costs per tonne of $17.50 are per tonne of ore, not per tonne of copper. The costs per tonne should therefore be multiplied by 30.9mt and not by 372,000 of copper equ.

This gives mining & processing costs of $541m and not $6.5m as state above.

Just slightly out by $534.5m...
