Seems like Ken is avoiding putting a number on the Fe2O3 percentage. The Fe2O3 is plotted in the PLS announcements, however the scale of the plot means you can not obtain the required resolution to extract the number. Imagine if the Fe2O3 is too high and he actually admits it! Maybe that's the best thing to do instead of beating around the bush. It has to come out eventually what the percentage is. State the percentage and how they are going to work around it, if it's too high.
