A game-changing discovery has been made in the U.S.—the world’s largest lithium deposit was found inside an ancient supervolcano on the Nevada-Oregon border. The McDermitt Caldera holds an estimated 40 million metric tons of lithium, nearly half of the world’s known reserves and twice as much as Bolivia’s famous salt flats. Since lithium is essential for batteries in smartphones, laptops, and electric vehicles, this find could reshape the global supply chain. With demand for lithium expected to skyrocket tenfold by 2050, the U.S. might finally reduce its dependence on foreign suppliers, especially China. In 2022, America imported 70% of its lithium-ion batteries, but this discovery could change everything. If mining begins as planned in 2026, the U.S. could become a major powerhouse in the lithium industry, fueling both innovation and economic growth.
