Have a look at the table on page 23 of 09/03/12 Updated Investor Presentation.
I believe the presentation is for the current total M & I.
Look at total pounds in the Indicated box in each table ie - 250ppm cut-off and 750ppm cut-off. 620ppm average and 1210ppm average respectively.
Now compare too todays . . . there is a small difference in total pounds due to the higher ppm used in todays announcement. 670ppm average and 1290ppm average
Hope this helps.
