Ann: Quarterly Activities Report - December 2020, page-95

Figures below were mostly taken from LPD's 2019 announcement :

... except that I added:

* Magnesium for Albermarle, taken from their own website.
* Added LKE at the end for comparison ( Can't find AGY's LiCO3 specification so did not include )



In terms of grade, 99.85 is even better than the 4 majors.

Did a colour map for the impurities so that dark green is best, followed by light green, then yellow, light orange, dark orange, then red being the worst.

So the more green or yellow, the better.

Did not do the colour map for Fe and Mg as the data is incomplete. Only Albemarle and LKE published its Mg impurity. No Fe impurity mentioned for GXY in the quarterly, so will be good to find out from GXY if there were none or too low.

So what we have is that GXY has:
* The lowest SO4 impurity
* Second lowest CaCO3 impurity
* Third lowest for Na and K impurity
* Overall, if you just focus on the colours, GXY have lower impurities than the 4 majors


Was trying to find Livent's Mg levels given that we are basically on the same area, to find a target Mg level to achieve or better, but Livent does not publish them. Who knows, they may have the same levels as GXY.

So the best we can compare with for Mg is with Albermarle. If we can reduce that 157 ppm to a little more than half, then we are on par with ALB.
