Considering the development of Sodium-ion cells is still proceeding apace – with commercial batteries already entering the market – trying to influence things by playing with Lithium supply is not likely to work out. Better to pivot and start using their institutional oil extraction knowledge to do brine extraction and either sell the brine on to a refinery, or build some lithium refineries.

If we were making bets, that’s what I bet Exxon/Mobil is actually planning.

Most of the smackover formation is below 3000m, a lot is below 10km, and there is but a small section relatively near the surface.

Honestly if they’re smart they’ll use their knowledge to actually mine the stuff – the EV genie is not going back in the bottle, if they don’t get with it someone else will. And a deposit that significant would be hard to sit on without the government putting a lot of pressure on you or trying to pry you back off it given the current dependency on China etc.
