Zanskar's discovery of the Big Blind geothermal site in Nevada further validates their AI-aided prospecting capabilities even for blind geothermal systems.
Zanskar has announced the discovery of the Big Blind geothermal system in western Nevada, considered to be the first blind geothermal system identified and confirmed to be commercial in the United States in over 30 years.
The Big Blind site, as the name implies, is a site with no surface geothermal manifestations nor history of geothermal exploration or prior well data. Using its prospecting toolkit and AI prediction engine, Zanskar discovered a geothermal anomaly at the site and identified viable drilling targets.
The company drilled two intermediate depth wells in July and August 2025. This confirmed the presence of a permeable geothermal reservoir with temperature of 250°F (121 °C) at around 2700 feet (823 meters) depth. These conditions exceed minimum thresholds for utility-scale geothermal power and are considerably more ideal than background subsurface conditions.
The exact potential capacity of Big Blind will have to be confirmed by additional exploration drilling and reservoir characterization, but Zanskar states that naturally occurring geothermal systems similar to Big Blind can produce over 100 MWe using standard power plant technology.
The discovery of Big Blind follows Zanskar’s success in testing and confirming geothermal resources at Lightning Dock in New Mexico and Pumpernickel in Nevada. Zanskar also states that it already has a deep bench of additional geothermal anomalies that are slated for deeper exploratory drilling.
Zanskar’s stream of new geothermal discoveries will enable large energy consumers, governments, and utilities to scale their adoption of clean, firm, geothermal energy. Zanskar’s AI-native technology is both cost effective and highly repeatable, turning hidden geothermal resources into solutions for addressing increased energy demand and its resulting cost pressures.
“Naturally occurring geothermal systems are commonly overlooked for being ‘too difficult to find,’ or ‘too sparse to matter’, a narrative being dispelled by Zanskar’s ability to repeatedly find new geothermal hotspots such as Big Blind,” said Joel Edwards, co-founder and CTO at Zanskar.
“What’s often called “conventional geothermal” is a tremendous, untapped source for reliable clean, firm power at low costs in the western U.S. We’re excited that after years of behind-the-scenes work finding these new geothermal hotspots, we’re now proving they can support power generation facilities with the drill bit.”
