No, No Floppy.  Read the link.  There wouldn't be any "negotiation" required over the 3% royalty.  That number is lifted straight off the refiner's statement.  More likely a profit share became payable because production was better than expected and phase IV capital spending went a little slower than expected.  Of course, accountants can argue endlessly about the definition of "profit", so I can see some "negotiation" possibly being required.  Also, I think Centamin has made a bit of a windfall profit on the decline of the Egyptian pound.  Their revenues are in gold, but the payroll and a lot of their accounts payable are in the local currency.   Small wonder they are sitting on the financial report... No point in angering  the locals...
