Pavle Jeremic, CEO and founder of Aether "Concentration of lithium in the Salton Sea is some of the highest in the United States, you know, 500, 600, 700 parts per million comapred to this vast majority of the lithium in the world is actually at lower concentrations, 100 to 250 parts per million. If I can extract that 50 parts per million lithium instead of 500 parts per million, I have to pump 10 times the amount of water to extract that lithium. Most people that are claiming to be able to extract lithium from the Salton Sea are at about US$4,500 per ton. For us, at least in the system were designing, we'd probably be at a little below $2,000 per ton. We'll get dramatically better, closer to $1,000 per ton over time. "
