Major Lithium Deposit Found in McDermitt Caldera: A major lithium deposit found in McDermitt Caldera along the Nevada-Oregon border could be a game-changer for the U.S. electric vehicle (EV) industry. This incredible find, estimated to hold between 20 and 40 million metric tons of lithium, could become the world’s largest known lithium source. As the U.S. ramps up clean energy efforts, this discovery might just be the “white gold rush” America needs.
Beyond its sheer size, the find is loaded with national significance. It could reduce our dependency on foreign imports—especially from countries like China—and create new opportunities for green tech, jobs, and energy independence.

The discovery of a massive lithium deposit in McDermitt Caldera may just supercharge America’s clean energy future. With the right leadership, investment, and respect for Indigenous rights and the environment, this could mark a turning point in the U.S. EV and battery industry.
Balancing energy independence with ecological and cultural responsibility will be the true test of how we move forward.
What Is the McDermitt Caldera?
The Geologic Jackpot
The McDermitt Caldera was created by a massive volcanic eruption over 16 million years ago, forming a crater now packed with lithium-rich claystone. Its unique geology made it a prime spot for mineral explorers, and now it could be the largest lithium deposit ever uncovered.
This region is remote, rugged, and sits on public and tribal lands—making it a politically and culturally complex site.
Why This Lithium Find Matters
Powering America’s EV Dreams
Lithium is the backbone of modern batteries—from your smartphone to your Tesla. With Biden’s goal of having EVs make up 50% of car sales by 2030, the demand for lithium is skyrocketing.
Currently, the U.S. imports over 75% of its lithium, mostly from Chile, Argentina, and China. This new source could:
- Fuel domestic battery production
- Lower EV costs
- Create thousands of mining and processing jobs
- Reduce geopolitical risk
What’s Being Planned?
Lithium Americas Leads the Way
Lithium Americas Corp. has plans for a large-scale open-pit mine project, often referred to as the Thacker Pass project. Backed by private investment and conditional federal approval, it’s expected to begin operations by 2026.
Highlights:
- Projected output: 60,000 tons/year
- Lifespan: Over 40 years
- Jobs: 1,000+ during construction, 300+ permanent
The Cultural and Environmental Catch
Indigenous Land and Heritage
The proposed mine overlaps with ancestral lands of the Paiute and Shoshone peoples, and Thacker Pass (known as Peehee Mu’huh) holds deep spiritual and historical value. Local tribal leaders and environmental groups have voiced strong opposition.
- Potential disruption of sacred sites
- Lack of early tribal consultation
- Legal battles are ongoing
Environmental Risks
Lithium mining isn’t clean. It poses risks such as:
- Water table disruption
- Toxic chemical runoff
- Threats to endangered species like the sage-grouse and Lahontan cutthroat trout
Proper environmental review, mitigation plans, and community input will be key.

Major Lithium Deposit Found in McDermitt Caldera Breakdown
- Extraction: Lithium-rich clay is mined from the ground—usually by open-pit techniques.
- Processing: The ore is crushed, leached with acid, and lithium is separated chemically.
- Refinement: Lithium carbonate or lithium hydroxide is refined for use in batteries.
- Manufacturing: U.S.-based battery plants use lithium to create cells for EVs, power tools, and storage systems.
- Market Impact: Domestic sourcing reduces costs, increases job creation, and boosts national security.
