Lithium Mine Beneath US Supervolcano Sparks Environmental Fears and Potential Disaster
A massive lithium deposit, potentially the largest ever discovered, has been identified within the McDermitt caldera on the Nevada-Oregon border, estimated to contain 20 to 40 million metric tons of the element. This lithium-rich clay formed from volcanic ash and mud in a long-lived lake, with hydrothermal fluids later leaching lithium from volcanic glass. The deposit’s high lithium concentrations, close proximity to the surface, and large size make it particularly promising for future mining efforts to meet the growing global demand for lithium-ion batteries. However, extracting this resource presents environmental challenges and concerns for local communities. This discovery offers valuable insights into the formation of lithium deposits within volcanic systems.
