IsoEnergy Initiates Bulk Sample Program at the Tony M Uranium Mine in Utah, a Key Step Toward a Potential Restart Decision
TORONTO, Jan. 7, 2026 /CNW/ - IsoEnergy Ltd. ("IsoEnergy" or the "Company") (NYSE American: ISOU) (TSX: ISO) is pleased to announce a bulk sample program (the "Bulk Sample") at its 100%-owned Tony M uranium mine in Utah ("Tony M" or the "Mine"). The Bulk Sample is designed to collect key technical, operational, and economic data required as one of the steps to support a potential production restart decision at one of the few fully permitted, past-producing conventional uranium mines in the United States.
The Bulk Sample program will involve the extraction of up to 2,000 tons of mineralized material over a 12-14-week period (which commenced late December 2025) and will be executed using contract mining services provided by GenX Mining Contractors, LLC of Spring Creek, Nevada. Mineralized material recovered during the program will be transported to the White Mesa Mill in Utah, owned by Energy Fuels Inc., for processing.
With U.S. utilities increasingly focused on securing domestic uranium supply and limited near-term production capacity available, IsoEnergy believes Tony M represents a rare opportunity to advance a permitted, infrastructure-ready uranium mine toward potential restart without the need for costly and timely mill construction/refurbishment or major permitting initiatives. The Bulk Sample is a critical step in defining the scope and economics of a future production plan at Tony M. This work aligns with U.S. federal initiatives focused on rebuilding domestic nuclear fuel supply chains and enhancing energy security through increased domestic uranium production.
Upon completion of the Bulk Sample, IsoEnergy expects to evaluate the results alongside ongoing optimization studies to determine next steps, which may include advancing detailed mine planning, finalizing restart sequencing, and assessing the timing of a potential production decision.
Highlights
| • | Bulk Sample Designed as a Decision Gate Toward PotentialRestart |
|---|---|
| o | Low-risk, limited-scope program structured to generate real-world<br>mining, processing, and cost data required to evaluate a potential restart decision. |
| --- | --- |
| o | Results expected to inform mine planning, sequencing, and<br>commercial production assumptions. |
| --- | --- |
| • | De-Risking Mining Methods and Cost Structure Under OperatingConditions |
| --- | --- |
| o | Establishes actual contract mining costs and validates assumptions<br>used in economic models. |
| --- | --- |
| o | Refines mineral material-control strategies to minimize dilution<br>and maximize delivered grade, including testing dilution-control techniques in a production-style environment. |
| --- | --- |
| • | Processing Pathway Established Through Existing Toll MillingAgreement |
| --- | --- |
| o | Mineralized material to be processed at the White Mesa Mill,<br>eliminating the need for new mill construction and materially reducing capital intensity and execution risk. |
| --- | --- |
| o | Enables IsoEnergy to focus capital and effort on mine<br>restart and optimization rather than downstream infrastructure. |
| --- | --- |
| • | Production-Ready Underground Systems and Execution Tested |
| --- | --- |
| o | Trials ventilation, ground-control, and underground operating<br>procedures ahead of full-scale mining. |
| --- | --- |
Philip Williams, CEO and Director of IsoEnergy, commented, "The Bulk Sample at Tony M is a major milestone in advancing one of the few restart-ready uranium mines in the United States. This program is designed to generate the real-world data we need to evaluate a potential full scale production restart under current market conditions. With permitting, infrastructure, and toll milling already in place, Tony M has the potential to be among the next conventional uranium mines in the U.S. to return to production as demand for secure domestic supply continues to grow."

Progress on Tony M Mine Work Programs
During 2025, IsoEnergy advanced a series of initiatives designed to strengthen the operating and economic profile of Tony M including, reducing the uranium production royalty on the Utah Trust Lands Administration (SITLA) lease from 8% to 3%, High-Pressure Slurry Ablation testing, which has demonstrated the potential to recover more than 90% of the uranium into roughly 25% of the original mass and mineralized material-sorting testwork completed in October which achieved over 90% recovery into roughly 50% of the original mass for material amenable to sorting. In parallel, an enhanced evaporation study has shown that Landshark evaporators eliminate the need for evaporation-pond expansion and reduce both permitting timelines and capital requirements. Together, these work programs support the Company's strategy of systematically de-risking Tony M and improving the economic framework for a future production decision.
About Tony M Mine
The Tony M Mine is located in eastern Garfield County, southeastern Utah, approximately 66 air miles (107 kilometers) west northwest of the town of Blanding and 215 miles (347 kilometers) south-southeast of Salt Lake City. The project is the site of the Tony M underground uranium mine that was developed by Plateau Resources, a subsidiary of Consumer Power Company, in the mid-1970s.
Uranium and vanadium mineralization at the Tony M mine is hosted in sandstone units of the Salt Wash Member of the Jurassic age Morrison Formation, one of the principal hosts for uranium deposits in the Colorado Plateau region of Utah and Colorado.
Tony M has the following current mineral resource estimate:
