I am glad you are posting the daily benchmark prices-if people will look in Maxs dd compilation they will see iron prices were only 10-14/ton til 2002

most juniors have a cost of production below 25/ton so that still leaves a large profit

A long time ago cwrn noted the cement product alone was paying much of the overhead
