production figures from TR-DRC... total produced figure of 18,849,600lb is incorrect from TR-DRC.... that figure is only copper produce, you forgot to include 21215040lb of gold produced and also the large figure of lbs of silver produced... the total cost are for all copper/gold/silver, not only copper as you have worked it below...
