There are over 200 billion tonnes of lithium in seawater, it's just the least economical out of all sources of this element.

There are plenty more, but they're explored only when there's a price hike.

AFAIK, the brine pits are pretty economical, they just require ocean access.

What I'm somewhat surprised about is that we've not seen synergies with desalination and ocean mineral extraction. IDK why the brine from a desalination plant isn't seen as a prime first step in extraction lithium, magnesium, and other precious minerals from ocean water.
