IsoEnergy Provides Update on its U.S. Mine Restart Plans with Advancement of the Tony M Mine in Utah
Tony M, along with our Daneros and Rim projects, is one of three past-producing, fully-permitted, uranium mines in
-
Reopening of the Underground and Comprehensive Work Program – The Company plans to reopen the main decline into the Tony M mine and gain underground access by the end of H1-2024. This critical step is expected to facilitate the assessment of the mine's underground conditions, enable direct analysis of the uranium mineralization in place, and allow for the collection of necessary data required to prepare an efficient mine plan. The work program also includes underground and surface geological mapping of the sandstone-hosted uranium and vanadium mineralization to allow for more precise extraction plans for inclusion in an updated economic study.
-
Technical/Economic Study Planned (the "Study") – The Company intends to complete a Study, which will provide further details on a potential restart date and a mine plan that will provide production plans and rates, expected operational costs and capital requirements.
-
Toll-Milling Arrangement with EFR – IsoEnergy has a toll milling arrangement with EFR for its Tony M, Daneros, Rim and Calliham projects, which guarantees the Company access to the
White Mesa Mill , the only operational conventional uranium mill in theU.S. OnDecember 21, 2023 , EFR announced its plans to restart theWhite Mesa Mill uranium circuit in 2025. As a result, and to support additional feed,IsoEnergy intends to deliver ore to the Mill in time for the restart of the uranium circuit. -
Commencement into Multi-Asset Production – The reopening of the Tony M mine is a first step in
IsoEnergy's plan to becoming a multi-asset uranium producer.IsoEnergy is also evaluating plans to restart operations at the Daneros and Rim mines, both of which were previous producers of uranium and vanadium, and are currently permitted for production. -
Staffing up for Re-Opening – The Company has appointed
Josh Clelland to the position of Director of US Engineering and Operations, to manage the reopening of theTony M Mine , and advancement of the Company's other US-based uranium projects. Josh is a ProfessionalMining Engineer with over 20 years of experience in the mining industry, including significant experience operating in both underground and open pit environments. He joins us from a major global gold producer where in his most recent role he was a Superintendent of Mine Operations. Josh's additional experience includes a Corporate Development role at a major producer, technical advisory at a major international mining consulting firm, and research at a Canadian brokerage firm, during which time Josh earned his Chartered Financial Analyst designation.
Multiple work streams are now underway to move our flagship Tony M Mine back toward production in 2025, in line with the timing Energy Fuels has announced for its

The Company is continuing to advance plans to reopen the underground mine workings in preparation for a potential restart of Tony M. This work program includes updating mine ventilation and escape plans, maintenance of the existing ventilation fans and power infrastructure, surveying of the underground mine workings, rehabilitation of mine workings and ground support as needed, and upgrading and/or replacement of utilities.
Rehabilitation of the underground is expected to take place during H1-2024, followed by planned geologic mapping and sampling alongside mine planning ahead of anticipated completion of the Study. The Company currently expects to utilize contract mining initially. In addition to the 18 miles of underground development, including multiple production headings, the Mine has complete surface infrastructure in place (Figure 2).

- Reported in the Technical Report on the
Tony M Project , Utah, USA Report for NI 43-101, prepared for Consolidated Uranium Inc. bySLR International Corporation ;Mark B. Mathisen , Qualified Person, Effective DateSeptember 9, 2022 . - CIM (2014) definitions were followed for all Mineral Resource categories.
- Uranium Mineral Resources are estimated at a cut-off grade of 0.14% U3O8.
- The cut-off grade is calculated using a metal price of
$65 /lb U3O8. - No minimum mining width was used in determining Mineral Resources.
- Mineral Resources are based on a tonnage factor of 15 ft3/ton (Bulk density 0.0667 ton/ft3 or 2.14 t/m3).
- Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
- Past production (1979-2008) has been removed from the Mineral Resource.
- Totals may not add due to rounding.
- Mineral Resources are 100% attributable to
IsoEnergy and are in situ.
