When assessing cashflow you should look at the detail and not just the net cashflow. That cashflow you posted for NQM has a payment of $4.1 million for an environmental bond. Take that out and cashflow is plus $3m.
You also need to look for other non-recurring items - I don't know NQM and where they are at development wise but given it appears they are now mining are cash costs for mine development and plant & equipment going to be at the same levels in future periods?
