A giant lithium deposit discovered in the U.S.

10 january 2024

The largest lithium deposit on Earth is probably located at the junction of the states of Nevada and Oregon (USA).

The gismeteo.ru news portal reports that, according to recent estimates, there are deposits of 40 million metric tons of lithium under the caldera of the McDermitt supervolcano. The area of the caldera is about 1,575 square kilometers.

If the examination of the deposits confirms the assumptions of experts, the deposit will receive the status of the largest on the planet, ahead of the Bolivian ones containing 25 million tons of lithium.

According to scientists, the discovery has significant significance for the global lithium market and will affect prices, logistical security and geopolitics.

According to a study conducted by the Lithium Americas Corporation, lithium deposits under the caldera were formed after an eruption that occurred approximately 16.4 million years ago. Later on, the minerals rose to the surface from the depths, forming a rich scattering of smectite clays with a high concentration of lithium.
