Yes Auswedes, it's in their accounts.
Have you read the Competent Persons report?
I get 205,000 tonnes of bought in coal, for a cost of ZAR68million for a sale price of ZAR736 per tonne = ZAR151million
This is based on 2012 / 2013 intakes and pricing which hasn't happened yet.
They buy in stranded coal from a nearby mine, wash it and sell it for export (hint - for a profit).
