Scientists think a massive volcanic eruption left behind enough lithium at the McDermitt Caldera to power the EV transition for decades.
The site of a former supervolcano at the Oregon and Nevada border could turn out to be the largest lithium deposit in the U.S. and, possibly, the world. New research suggests that the McDermitt Caldera could contain over 132 million tons of lithium, which is enough to meet global demand for decades. This could give the U.S. a massive boost to its EV supply chain, and from a domestic source, no less.
The amount of lithium at the caldera has the potential to dwarf that of the former largest known lithium deposit in the world, the Atacama Salt Flat in Bolivia, according to the Independent. Based on volume alone, McDermitt could yield 12 times more lithium than the Atacama Salt Flat. And, more importantly, the lithium that miners plan to extract from the caldera can be collected in a way that’s allegedly less harmful to the environment.
