Uranium Energy Corp. began producing uranium at its Burke Hollow site in Bee County, South Texas, in April 2026, marking what the company calls the first new in-situ recovery (ISR) uranium mine to open in the United States in more than a decade. The project holds an estimated 6 million pounds of uranium resources, according to a technical report filed with the Securities and Exchange Commission, and its startup arrives as American utilities work to secure domestic fuel supply amid rising reactor demand and tightening trade policy on foreign uranium.
“Burke Hollow is the world’s newest operating ISR uranium mine,” CEO Amir Adnani said in the company’s announcement, calling the project a cornerstone of UEC’s U.S.-focused production platform. He said the company intends to scale output from Burke Hollow alongside its restarted operations at Christensen Ranch in Wyoming.
Why it matters now
The United States operates 93 commercial nuclear reactors that consume roughly 40 to 50 million pounds of uranium per year, yet domestic mines have supplied only a fraction of that total for decades. Most reactor fuel has come from Kazakhstan, Canada, Australia, and Russia. A federal ban on Russian enriched uranium imports signed into law in 2024, combined with ongoing discussions about a national uranium reserve, has pushed utilities and policymakers to prioritize homegrown supply. Burke Hollow’s launch puts new American pounds into a market where domestic production has been negligible since the mid-2010s.
The last greenfield ISR uranium operation to start up in the lower 48 was Ur-Energy’s Lost Creek mine in Wyoming, which poured its first yellowcake in 2013. Since then, low prices and cheap foreign supply kept most U.S. projects on standby. Spot uranium prices have climbed from below $30 per pound in early 2021 to above $60 per pound in recent trading, a level that has coaxed several mothballed projects back toward production. UEC restarted Christensen Ranch in 2023 and has framed Burke Hollow as the next step in building a multi-site hub-and-spoke operation across Texas and Wyoming.
How the project reached production
Burke Hollow’s path to startup ran through both federal securities regulators and the Texas Commission on Environmental Quality (TCEQ). UEC disclosed the production milestone in a Form 8-K filed with the SEC (the link points to UEC’s recent 8-K filings on EDGAR; readers should locate the specific filing by date), a legally binding disclosure that carries liability if material statements prove false. The filing attached the production announcement as Exhibit 99.1.
On the state side, TCEQ granted uranium recovery permit UR03075 after a contested case hearing tracked under SOAH docket 582-26-02866, according to the agency’s public hearing record. The contested hearing process means at least one party raised formal objections that required adjudication before the permit could be issued, a higher bar than a routine administrative approval.
The 6 million pound resource estimate comes from UEC’s S-K 1300 Technical Report Summary, also filed on the SEC’s EDGAR system. That figure carries a Qualified Person sign-off required under federal mining disclosure rules, which replaced older industry-only reporting codes with auditable, investor-grade resource classifications.
Outside perspectives
Independent nuclear energy analysts have noted that new domestic ISR capacity, while welcome from a supply-security standpoint, still represents a small fraction of total U.S. reactor fuel needs. The country’s 93 reactors require tens of millions of pounds annually, and a single project ramping up from zero will not close that gap on its own. Whether Burke Hollow can scale quickly enough to be material depends on wellfield performance data that UEC has not yet reported.
Environmental groups in South Texas have historically raised concerns about ISR mining’s potential effects on groundwater quality and aquifer integrity. The contested hearing at TCEQ confirms that at least one party objected formally to the Burke Hollow permit, though the substance of those objections has not been detailed in publicly available records. Residents near ISR operations elsewhere in Texas have pointed to the difficulty of monitoring underground fluid movement once injection begins, an issue that independent hydrogeologists say requires robust baseline water-quality data and ongoing third-party sampling to address. UEC has not published such baseline data for Burke Hollow.
From a regulatory standpoint, TCEQ’s role is to enforce the conditions of permit UR03075, including any monitoring, reporting, and remediation obligations. The agency has not released the full text of the permit with its specific conditions, making it difficult for outside observers to evaluate the rigor of oversight that will apply during ramp-up. The Nuclear Regulatory Commission, which oversees radiological safety at uranium recovery facilities, maintains its own licensing framework, but the interplay between state and federal oversight at Burke Hollow has not been publicly detailed.
How ISR mining works at Burke Hollow
In-situ recovery skips the open pits and underground tunnels of conventional mining. Instead, operators inject an oxygen-enriched solution into uranium-bearing sandstone formations through a grid of wells. The solution dissolves uranium from the rock. A second set of wells pumps the uranium-laden fluid to the surface, where it is processed into yellowcake concentrate at a central plant.
UEC has described a hub-and-spoke model for Burke Hollow in which ore from satellite wellfields feeds a shared processing facility. The approach is designed to keep capital costs lower by spreading plant infrastructure across multiple deposits. ISR operations are generally faster and cheaper to bring online than conventional mines, which is one reason the method dominates U.S. uranium production. However, UEC has not disclosed projected cash costs per pound or internal rates of return specific to Burke Hollow in any SEC filing tied to first-year output.
What remains unclear
Several gaps separate the verified startup from a full picture of Burke Hollow’s near-term performance.
Permit conditions. No publicly available TCEQ document spells out the monitoring requirements, discharge limits, or post-approval obligations attached to permit UR03075. Without that detail, outside observers cannot independently assess how tightly the state will oversee the mine’s environmental footprint during ramp-up.
Resource versus production. The 6 million pound figure reflects geological modeling and drill-hole data, not confirmed extraction rates. UEC has not filed updated resource or reserve numbers based on initial wellfield performance, so the gap between modeled geology and actual output remains an open question. First-year production targets have not appeared in any public filing.
Environmental objections. The contested hearing confirms that formal objections were raised, but the substance of those objections and their resolution are not detailed in the publicly available hearing notice. It is unclear whether concerns focused on groundwater quality, aquifer pressure, cumulative regional effects, or other dimensions of ISR operations. No published monitoring baselines have surfaced to allow independent tracking of water quality once injection wells are running.
Sales strategy. UEC has not disclosed whether Burke Hollow’s output is hedged through forward contracts or will be sold at spot prices. ISR projects carry relatively low capital costs but remain sensitive to price swings during ramp-up, when production volumes are still climbing toward nameplate capacity and per-pound costs can be volatile.
Wellfield development pace. ISR operations typically progress in phases, with initial well patterns tested and expanded as operators learn about flow rates, permeability, and recovery factors. UEC has not provided a schedule specifying how many well patterns will be installed in the first year or how quickly it expects to reach steady-state production.
What to watch next
The clearest test of Burke Hollow’s viability will come in UEC’s next quarterly filings on EDGAR, expected by mid-2026. Those disclosures should reveal whether wellfield performance matches the resource model and whether the company can convert permitted capacity into actual pounds of yellowcake at sustainable margins. Production data will also begin to fill in gaps on unit economics, environmental compliance, and development pace.
For the broader U.S. uranium sector, Burke Hollow serves as a real-time case study. If the project ramps smoothly, it strengthens the argument that American ISR deposits can be brought online quickly enough to matter in a market still dominated by foreign supply. If early results disappoint, it will underscore the persistent gap between resource estimates on paper and pounds in the drum, a gap the industry has struggled to close for years.
