There's some big difference between brine and hard rock deposits, varying from grade, extractable resource, annual production capacity, output grade etc.
Lithium is just a small by product for a brine deposit.

Most brine lithium grade is very low, although SQM has a highest grade of 0.20% which is probably why Chinese companies have been interested in bidding for a stake in SQM for billions of dollars.


AVZ, grade is around 1.5% Li2O, with 200m thickness, that will make huge difference, imo.
