Well Benjamins I am glad you are across all the permutations.
For Hindmost the best I can do is as follows :-
Go to
http://www.ironroadlimited.com.au/investor-centre/company-reports
and read 18.11.16 AR P7 Operating cost has been estimated at US$37.72
Go to
http://www.ironroadlimited.com.au/investor-centre/presentations
and read 16.10.16 AGM P7 At this page they recognise that they need a cost of $40 to be in lowest quartile
While at /presentations open 13.4.15 and at P8 there is a Metalytics table showing IRD @ $42 cost
I know that I have seen an up to date Metalytics table showing IRD in the bottom quartile but I can't give a reference address
Since these dates all the iron ore producers have reduced their costs.
FMG and RIO etc have stripped out 50% savings
I don't see why IRD cant do the same after all they will have new equipment and no dump truck leagcy.
