At a livestreamed event in late March, EnergyX CEO Teague Eagan introduced Project Lonestar, a lithium production initiative in East Texas. The project could reflect a broader effort within the United States to explore domestic sources of lithium and reduce reliance on overseas processing as demand for batteries continues to expand.
While the event highlighted EnergyX’s momentum and ambition, it’s important to note that Project Lonestar is a demonstration plant designed to test and refine processes. While the facility may not confirm large-scale commercial viability, the project represents a step toward domestic development of direct lithium extraction (DLE).
EnergyX describes Project Lonestar as the largest direct lithium extraction demonstration plant in the United States, with a potential annual production capacity of approximately 250 metric tons of lithium. Though that number may seem paltry compared to global production levels, which exceeded 290,000 metric tons in 2025, the implications of Egan’s announcement could be significant for America’s lithium production trajectory if EnergyX accomplishes what it aims to. If successful, the new facility could enable lithium to be efficiently extracted, processed, and scaled domestically in the United States using next-generation technology.
A Testing Ground for American DLE Production
Although the United States is not lacking in lithium resources, it has historically lagged in refining and processing capabilities. With much of the world’s lithium conversion processed overseas, American supply chains contain gaps and vulnerabilities that were particularly obvious in the past decade, when demand for lithium batteries for electric vehicles skyrocketed.
If project Lonestar reaches its proposed potential, it could be a step toward closing those gaps and altering the course for American lithium processing. Project Lonestar could demonstrate that high-quality lithium production may be possible here at home, without reliance on overseas supply.
During the event, Egan conveyed the urgency of this effort, noting that the demonstration plant’s development was completed in roughly a year. While that construction timeline is admirable, the facility’s performance will ultimately determine its broader impact. In the long term, Project Lonestar will need to consistently execute uptime, recovery rates, and cost efficiency to prove itself on American testing grounds.
As demand for lithium has increased over the past decade and a half, lithium consumption has risen in tandem, making it more urgent than ever that American lithium production keep pace with global demand. Despite electric vehicles beginning as a niche market, they have exploded into tens of millions of vehicles sold annually, with little to no sign of losing momentum.
Meanwhile, grid-scale energy storage systems have expanded at an alarming pace. In addition to emerging technologies such as drones and robotics, new layers of demand have further underscored the need for rapid DLE expansion domestically.
Location & Tech: Potential with Open Questions
Project Lonestar is located in the Smackover region between Texas and Arkansas, a massive underground brine formation that spans across parts of the southern United States. EnergyX has secured access to tens of thousands of acres in this region, positioning itself at the forefront of what could become a future hub for domestic lithium processing. While traditional mining operations rely on hard-rock extraction or sprawling evaporation ponds, this resource can be accessed through subsurface brine, supposedly unlocking new opportunities for scalability and efficiency.
“This is the next chapter of American-made critical minerals,” Egan stated. While Lonestar’s location is certainly noteworthy, the technology it will be testing could have greater implications for lithium processing in the future. For decades, lithium production relied on methods that were slow, land-intensive, and water-intensive. Evaporation ponds alone could take more than one year to produce viable lithium and require extensive surface areas to operate. However, EnergyX claims its new technological advancements dramatically compress that timeline and surface area, allegedly hypothetically enabling lithium extraction in a matter of days.
Egan claims that Project Lonestart will leverage advanced technology, combining methods such as solvent extraction, adsorption, and membrane systems to provide a streamlined platform for modern energy demands. The EnergyX CEO certainly has towering ambitions for Project Lonestar; if they prove true, it could be significant for American lithium.
The company leveraged a modular, prefabricated design philosophy, enabling components to be built off-site and assembled efficiently in the field. This construction system may be more commonly associated with aerospace engineering operations than with traditional mining facilities, but it signals the urgency with which EnergyX is operating.
What Moving From Demonstration to Scale Will Take
EnergyX has indicated that Project Lonestar is an early step in a broader commercial vision, indicating plans to expand production capacity in the future. The facility currently serves as a testing ground where the company gathers data, outlines and refines processes, and evaluates scalability potential.
At the same time, the history of DLE initiatives has included numerous demonstration and pilot projects that failed to transition to full-scale production. High costs, durability, environmental impact, and operational consistency have often posed challenges that become clear over time. If EnergyX wishes to succeed where others have failed, it will need to overcome these hurdles during this demonstration phase.
With plans to expand in the future and develop a full-scale commercial operation, Project Lonestar could be a forerunner of a brighter future for American lithium production and processing. However, this will not be without its challenges.
From a broader perspective, American investors have increasingly recognized that control over critical minerals is essential to the future of energy. The global economy is making shifts towards electrification. The ability to produce and process minerals like lithium domestically has become a strategic necessity, more than just an economic advantage.
Whether DLE and other endeavors, such as Project Lonestar, will play a significant role in the future remains an unanswered question. EnergyX has certainly taken a step in that direction, but time will tell whether the journey is long or short-lived.
