The 132kg comes from my infinite knowledge bank of sheet that I know from many years of dealing in sheet, if you doubt my figures go out read some books do some work talk to some people and find out it's correct.

Also even if it wasn't correct the amount of material doesn't have any baring on the outcome of the calculation make it 10kg or 1000kg or 1billion tons the ratios of gold stay the same, the two 4m figures will always produce a larger amount of gold.

And it's not a big call it's math, math isn't a call it isn't an opinion 1+1 =2 thats isn't a call it's just the result of the calculation.

Companies mess us figures all the time, I dozens of miscalculations a year, try writing up dozen of reports and never make a mistake we are only human, it's really not a big deal at all.
