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.
Neighbors around the caldera and the McDermitt deposit worry that large-scale extraction could damage an ecosystem that supports pronghorn antelope, sage-grouse, and other sensitive species.
A proposal from HiTech Minerals Inc. seeks to add roads and hundreds of wells to test for lithium in Malheur County.
Some see parallels to disputes in Nevada, where communities have fought lithium ventures they say threaten water sources.
As the push for lithium grows, local voices want to remain central in discussions about land use.
Sierra Club Oregon suggests it’s possible to develop lithium alternatives or find better ways to source the metal. »
