Study Points to Record Lithium Levels in the McDermitt Caldera, Between Nevada and Oregon. Assessments Suggest US$ 1.5 Trillion, With Effects for Tesla, Industrial Policies, and Local Communities.

The McDermitt Caldera, a supervolcano on the border between Nevada and Oregon, has returned to the center of energy debate after research suggested one of the largest lithium deposits on the planet. The area is home to the Thacker Pass project, a focus of investments and legal controversy.

For the industry, the discovery could lower battery costs and support the transition to electric vehicles in the U.S. For Elon Musk, who is building a lithium refinery in Texas, the move is likely to facilitate strategic supplies.

The geological formation of the caldera dates back to about 16.4 million years ago, when a colossal eruption created conditions for mineral concentration. Starting in 2023, new scientific data reinforced the hypothesis of hydrothermal enrichment with lithium in local clays.

What Was Discovered in the McDermitt Caldera

Peer-reviewed research indicates lithium levels of 1.3% to 2.4% in illite clays in the southern sector of the caldera, well above concentrations observed in common smectitic clays. This differential in content is what supports the expectation of high economic potential in the region.

The deposit is located around Thacker Pass, where Lithium Americas received federal regulatory approval and began construction in 2023. The project is cited as the largest lithium sedimentary resource in the U.S. and a pillar of a local battery supply chain.

The caldera measures 45 x 35 km and is part of the Yellowstone hotspot trail. The reference age for the massive eruption is ~16.4 Ma. These geological data help explain the anomalous concentration of lithium in lake sediments.

Why This Could Favor Elon Musk and Tesla

Tesla is progressing with a lithium refinery in Robstown (Texas) to produce lithium hydroxide at scale, with a goal capable of sustaining up to 1 million EVs/year at full capacity. Musk has described refining as a business that is like “printing money” due to the scarcity of global capacity. More domestic supply of ore or concentrate reduces costs and volatility at the refining stage.

Although GM is the industrial partner in Thacker Pass, any increase in supply in the U.S. is likely to benefit the entire supply chain, including Tesla, through pricing and logistics. Competition for long-term contracts with miners and refiners remains intense.

Reports from 2025 cite estimates that the caldera could supply hundreds of millions of EVs, a hypothetical figure that depends on recovery, technology, and price. Use with caution: this is a sector media projection, not a measured reserve.

Impact on Energy Security and the Battery Market

Domestic lithium production is a key piece in reducing import dependence and exposure to tariffs and price shocks.

In 2025, the press reported that the U.S. Department of Energy was moving to acquire a minority stake in Lithium Americas and in the JV with GM, linked to a billion-dollar loan for Thacker Pass. The goal is to accelerate supply and anchor the supply chain in the U.S.

If the average content in economically mineable areas proves to be at a high level (with peaks of 2.4% measured in samples), this improves margins and viability compared to low-content clays. Nevertheless, capex, water, reagents, and licensing remain critical variables.

In your view, does the industrial benefit outweigh the environmental and cultural risks? And who should lead access to this lithium: major automakers, new miners, or partnerships with local communities? Leave your comment.

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

Spain installs two giant pipelines 2.2 km off the coast to draw water from the Mediterranean and supply a megafacility capable of producing 200 million liters of drinking water per day.

Without wheels, iron, or machines, teams of up to 32 men would have dragged 2.3-ton blocks over wet sand up a ramp embedded in the pyramid itself, raising the structure in 20 to 27 years, according to a new computer model that reignites a millennia-old debate.

African country launched a $145 million project to rehabilitate 35 dams and drill deep wells seeking water stored for millennia beneath the desert, a plan that Captain Ibrahim Traoré’s government presents as a path to the country’s water sovereignty.

The largest highway concession company in Brazil already belongs to an Italian group, and now the railway sector may be next to receive billions in investments from Italy amid the progress of the Mercosur and European Union agreement.

A new study overturns the central idea we learned about planets and suggests that Earth is the exception rather than the rule; most rocky worlds in the galaxy may not have a core or mantle, just a single turbulent fluid extending to the center.
