So, wow, I just had a 15 minute conversation with the CEO of EnergyX. As I said, I am always cautious about any private company that does direct retail fund raising. In this case, it appears legit in that they did a $10M series A placement last year and are in the process of doing a series B offering with strategic investors. The retail offering is almost more of a marketing thing than anything else - they don't rely on that for fund raising, but as a way of getting the word out about their company. They don't actively advertise their retail fund raising except for having it on their website and occasional invited YouTube segments.
Also, they have filed with the SEC about all of this, and indeed here is their latest offering circular (which I just found and haven't read yet):

They are effectively pre-revenue, but that won't last long as they have six paid for pilot programs in the works now, including a few in the Salton Sea area (the so-called "Lithium Valley" in California). Assuming these pilots work as well as the free pilot they did under the auspices of the Bolivian government, commercial revenue will be done on a licensing basis, so they'll receive some percentage of lithium revenue going forward.
These guys have a play both in the existing lithium extraction industry in Bolivia and other brine evaporation areas, and in the newer areas like in the Salton Sea. Existing brine evaporation only extracts 50% of available lithium, their process moves that up to 94%. And given how expensive lithium is now due to EV demand, existing producers love that. And of course for new lithium deposits like the Salton Sea, traditional huge evaporation ponds is a non-starter so they
have to use technology like what EnergyX has.
