Ann: Initial metallurgical tests Generate Positive Results, page-6

"The core tested from a deeper hole representing longer term ore showed a predominance of petalite lithium mineralogy, which is a lower grade form of lithium. This result highlighted the need to characterise the overall orebody in terms of zonation, predominant mineral species and metallurgical response. "

Thoughts on this comment? Seems as though according to this at depth petalite is more predominant compared to the shallower samples showing a higher percentage of Spod.
