I not like to waste my time trying to argue with a blooming something or other. However, I will say that I have double-checked my calculations and I am comfortable with them. Furthermore, I believe I see the error in his calculations, whether intentional or unintentional ; I believe he has double-counted the process recovery rate, which is already factored into the amount of gold dore produced in the second quarter period, if you look at the calculations in his post. Also, 'Shipped' is not the same as 'Produced' nor as 'Settled'.
Bottom line: 'Figures lie, and liars figure'.
