Your figures are correct, I wasn't clear enough in my previous post.....
The Compounding factor of 2.1527 (conversion of ppm to Li20) was applied to the figures I presented, which is pretty normal for companies when reporting results. Also pretty much what I said, that the fact they are reporting in PPM means - MEH we have poo, lets report it in PPM

473ppm = (473*2.1527)/10000 = 0.1018% Li20
356ppm = (356*2.1527)/10000 = 0.076% Li20
564ppm = (564*2.1527)/10000 = 0.12% Li20

cheers
