McDermitt Caldera in Oregon is attracting attention for what could be one of the largest lithium deposits ever identified in the United States. Many view it as a potential boost for domestic battery production, while local communities voice concern over the impact on wildlife and cultural sites.
The excitement stems from estimates that value the deposit at about $1.5 trillion. Some geologists say these ancient volcanic sediments could contain between 20 and 40 million metric tons of lithium.
“This feature is 16 million years old, and we’re making decisions in a matter of years,” said Sammy Castonguay, a geologist at Treasure Valley Community College. Castonguay’s statement has stirred local debate over how the development might reshape the high desert. Industry advocates see a path to addressing the ballooning need for electric vehicle batteries.
