Comparison of Impurities to Bacanora FS, 

From Bacanora Feasibility (prepared by Ausenco, page 84).

Chinese battery Grade impurities.
1) Mg less than 70ppm (Tick for CYP).
2) Ca less than 160ppm (Tick for CYP)
3) Fe less than 10ppm (fail for CYP)
4) Al less than 50ppm (Tick for CYP).

Overall CYP are moving in the correct direction for being so early on in there processing tests.

So, maybe ask Don Mosher about this and if weestu could comment on his source of data ect. This could explain why we still wait, they could well be working to get the iron down to 10ppm from 40 or 50ppm.
