The cash cost excluded:
"depreciation and amortisation, corporate administration, sale, royalties, ocean freight, interest and financing costs".
An assessment of depreciation and amortisation is somewhere between $US15 to $US30 per tonne, but this is a non-cash items so while important it is not important with respect to cash.
Corporate admin - my guess $US8m per annum or $US1 per tonne.
Sales - have no idea - haven't we got all quantities going to Ansteel - but if KML has a sales force $US2m or $US25c per tonne.
Royalties $US1.40 per tonne refer to FMG 24 Feb 2016 Corporate presentation.
Shipping $US3.50 per tonne ditto.
Interest and finance costs - $US1.7b at 3% = $US51m = $US6.50 per tonne.
