So there are four companies planning pilot plants to suck brine out of the same Canadian resource, in the coming months. Production costs may be less than 75% of those paid by hard-rock miners. Arkansas and Texas have twice as much lithium in their brine, but only half as much as California.

Yet people think lithium prices won’t return to their 2018 levels, once supply meets demand? It may take a few years, but that’s how long it will take producers to recover their start-up costs. If DLE works on a commercial level (remember, there's no proof yet), it’s a game changer. Good news for consumers, bad news for suppliers. Not that there’s that much lithium in an EV battery anyway. But other storage devices will keep using it, until they find something better.
