It’s like when contractors do work for you, after they do some work they give you an invoice, and it can be paid within 30days or 60 or 90. That’s trade creditor.
They have 30M trade creditor debt....but they also have 17M stockpiles. The trade creditors costs are included in AISC... if we mine some gold at $900AISC .... some of the $900 go to the trade creditors.
