It's a no-brainer, there will be lithium brines in there, the whole salar basin is full of reasonably high grade lithium brine.
Proving up resources is another thing, that requires time, money and expertise, and resources like electricity and gas, which I'm sure AKE has a hold on there, and real estate to build ponds, so I imagine that's why Minera Santa Rita decided to stick with boron/Borax.
