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.

The McDermitt Caldera in Oregon holds a potentially massive lithium deposit, estimated at $1.5 trillion, sparking debate over its development. While proponents highlight its potential to bolster domestic battery production and alleviate reliance on foreign sources, concerns exist regarding the impact on sensitive wildlife, including pronghorn antelope and sage-grouse, and culturally significant Indigenous sites. The Bureau of Land Management’s limited public comment period has drawn criticism, mirroring similar disputes in Nevada over water resources. Balancing economic benefits with environmental protection and community input remains a central challenge.

A significant lithium deposit in central Ukraine, near the abandoned village of Liodiane, holds the potential for substantial economic benefit, with an estimated daily extraction capacity of 4,300 tonnes. However, development is stalled due to ongoing conflict and a controversial demand by the former US president for a significant share of Ukraine’s mineral wealth as payment for prior military aid. Ukrainian officials have rejected this demand, emphasizing the need for security guarantees before any deals involving their national resources are considered. The mine’s development, projected to cost $350 million, is contingent on the end of the war and securing international investment.
