Which is topped up by the Sth American subduction zone, one of the largest oceanic subduction zones on earth. 

Now consider how much Li is in the ocean and that it gets incorporated into the subduction process and spat out the volcanoes on the Sth American volcanic ridge and u have an inexhaustible supply of earth processed Lithium !!! With Galan being one of the biggest calderas ON THE PLANET. 

If Calderas does hold a mineable resource imo it will keep going as long as the earths tectonic plates keep moving and that should last out the Li battery technology cycle.
