I'm sure you're totally correct but I just wanted a ball-park number so grabbed the density (pure spod 3.1-3.2 g/cm^3). It's of the right order and I think shows that there will be more than 2kt shipped in September.
Considering I'm completely guessing the width of that pile as 20m I wasn't too fussy.
