So as a roughie comparison ....
....to have the equivalent amount of contained lithium as say AJM with and optimist grade of 10% Lithium (For simplicity sake) MOX would need to find a tenth of the Tonnage of AJM current jorc Approx
AJM Jorc 29.5mt @ 1.05% Lithium
MOX would need approx. 3mt @ 10% Lithium to have the equivalent contained lithium
Food for thought...
