ISO Isoenergy Ltd

- Expands land position in the Henry Mountains by over 400% 

TORONTO, Aug. 7, 2024 /PRNewswire/ - IsoEnergy Ltd. ("IsoEnergy" or the "Company") (TSX: ISO) (OTCQX: ISENF) is pleased to provide an update on the reopening of the underground and comprehensive work program at the Tony M uranium mine in Utah ("Tony M" or the "Mine"). As announced in a press release on February 29, 2024, the Company made a strategic decision to reopen access to the underground with the goal of restarting uranium production operations in 2025. The main decline at Tony M was successfully reopened on July 26, 2024, and several initiatives are now underway in preparation for the comprehensive work program, as detailed below.

Highlights

• Successful Reopening of the Underground – The main decline at Tony M is now reopened with initial observations of underground conditions indicating that the main decline and underground equipment shops are in good condition (Figure 1).
  
  
• Rehabilitation in Progress – Tomcat Mining is carrying out the rehabilitation of the underground, which includes scaling, installation of ground support and ventilation systems (Figure 2). This work is expected to take 8 to 10 weeks depending on the ground conditions encountered.
  
  
• Top Tier Consultants Engaged
  • SRK Consulting Limited, a leading international mining consulting firm, has been working with the Company on the design and implementation of the ventilation plans.
  • Call & Nicholas, Inc., an international mining consulting firm that specializes in geological engineering, geotechnical engineering, and hydrogeology, is working with the Company on the design and implementation of the ground control plans.
    
    
• Underground and Surface Mapping Commencing Shortly – As sections of the underground are made safe for entry, it is expected that the exploration/geology team will enter the Mine and begin to map the orebody from underground. This work, which will include a LiDAR survey, which is expected to commence in 3 weeks and will take approximately 1 month to complete.
  
  
• Upcoming Technical / Economic Study – Following completion of the rehabilitation and mapping programs, the Company intends to complete a technical and economic study, establishing production rates, operating and capital costs.

IsoEnergy CEO and Director Philip Williams stated, "The reopening of underground at Tony M is an important step in restarting production and establishing IsoEnergy as a near-term uranium producer. Long-term uranium prices have nearly doubled, from $41/lb U3O8 to $79/lb U3O8, since we acquired the Tony M, Daneros and Rim Mines in Utah, and with the exceedingly positive global outlook for nuclear power we expect that trend to continue. We believe that proven producing assets in tier one jurisdictions, like Tony M, will be highly coveted by end users making this an ideal time to pursue a restart. We have assembled a first-rate team of operators and consultants, who I would like to thank for their tireless efforts in advancing the project to this point, and we look forward to updating all our stakeholders on our progress as we move forward."

Tony M Mine Work Program

Over the last year, the Company has been working toward reopening the Tony M underground for access. Ensuring safe operations is paramount to the Company. The Company has engaged with the San Juan County mine rescue team as part of its plans. Site communications have been re-established, electrical systems have been upgraded and refurbished where necessary, including the installation of at least one new generator that meets tier 4 emission standards. Several new fans have been installed and will continue to be installed as part of the rehabilitation, along with the refurbishment of several of the existing fans. The Company is using state of the art radon monitoring.

The main portals were opened July 26 and Tomcat Mining has begun to assess ground conditions and work its way into the underground. While the Company estimates 8-10 weeks of rehabilitation work, this will be dependent on conditions encountered.

As sections of the underground are made safe for entry, it is expected that the exploration/geology team will enter the mine and begin to map out the orebody from underground. The Company is also in the process of contracting a surveying company to complete a LiDAR survey of the complete underground at Tony M, the first time any such survey has been completed at the Mine. This will be an important tool in the future mine planning at Tony M.

IsoEnergy has guaranteed access to the White Mesa Mill by way of a toll milling agreement with Energy Fuels, providing a significant advantage to the Company. The White Messa Mill is the only operational conventional uranium mill in the U.S. with licensed capacity of over 8Mlbs of U₃O₈ per year. The Mill is within trucking distance to Tony M.

Staking

The Flatiron area was acquired by staking 370 claims and winning bids on two Utah state leases totalling an additional 8,680 acres. This represents a 440% increase in IsoEnergy's Henry Mountain land package that is centred on the Tony M Mine.

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:
