Scarpa I had a look through a few announcements and came across this information
Code Strip Ratio Li2O
PLS 3.8:1 1.35%
MIN Wodgina 3.0:1 1.17%
AJM 2.9:1 1.06%
Mt Marion 3.3:1 1.1-1.4%
GXY 2.4:1 0.26% in DFS?

And in the 2011 Reed Resources ann I found Talison at 5.6:1 S/R. Not sure how accurate this is but way higher S/R than what I thought it would be.
So AVZ has an advantage on Strip Ratio compared to peers with 1:1
