IsoEnergy Highlights Strong Jurisdictional Rankings in the Fraser Institute’s 2026
Annual Survey of Mining Companies and Files Fiscal 2025 Annual Report
Toronto, ON, February 27, 202 6 – IsoEnergy Ltd. ( “IsoEnergy” or the “ Company”) (NYSE
American: ISOU; TSX: ISO) is pleased to highlight the results of the 2026 Annual Survey of Mining
Companies (the “Survey”) published by the Fraser Institute, underscoring the strength of the tier
one jurisdictions that underpin the Company’s globally diversified uranium portfolio and the filing
of its annual report on Form 40-F for the fiscal year ended December 31, 2025.
Highlights
• The 2026 Fraser Institute survey underscores the strength of IsoEnergy’s tier one
jurisdictional exposure, with Canada, the United States and Australia each placing
multiple jurisdictions among the global leaders in mining competitiveness.
• Canada continues to demonstrate global leadership, led by Saskatchewan, which ranked
3rd globally on the Investment Attractiveness Index (IAI), its sixth Top 10 placement in
seven years.
• United States remains globally significant, with Utah ranking 12th on the Policy
Perception Index (PPI), reflecting improving regulatory sentiment as IsoEnergy advances
its portfolio of past-producing assets toward potential restart.
• Australia showed notable upward momentum in this year’s survey, with three
jurisdictions where IsoEnergy holds projects ranking strongly : South Australia (4th on
IAI), Western Australia (6th on IAI; 3rd on the Best Practices Mineral Potential Index
(BPMPI)), and Queensland (13th on IAI) , highlighting the country’s compelling
combination of mineral potential and favourable mining policy.

Philip Williams, CEO and Director of IsoEnergy, commented,
“We are encouraged to see several jurisdictions within IsoEnergy’s portfolio once again rank
among the global leaders in the Fraser Institute’s 2026 survey. Saskatchewan’s sustained top-tier
performance, together with Western Australia’s meaningful advancement this year, reinforces the
geological quality and policy stability that underpin our asset base and guide our M&A strategy.
These results affirm our disciplined focus on advancing high -quality projects in ti er one
jurisdictions where we believe institutional capital can be allocated with confidence and long -
term value can be responsibly created.”
Summary of the Survey Results
In Canada, Saskatchewan’s 3rd -place global ranking reflects continued strong support from
industry respondents for both its mineral potential and policy framework . The province is
internationally recognized as one of the world’s leading uranium jurisdictions and hosts
IsoEnergy’s Larocque East Project, home to the Hurricane Deposit , t he world’s highest grade
published Indicated uranium Mineral Resource (48.6 Mlb U3O8 at 34.5% U3O8 Indicated, and 2.7
Mlb U3O8 at 2.2% U3O8 Inferred)1.
In the United States, specifically Utah, where IsoEnergy holds a portfolio of past-producing mines,
the state ranked 38th overall. The decline was driven primarily by a reduction in perceived mineral
potential; however, established and historically produci ng assets are expected to benefit from
Utah’s continued strength in policy perception metrics.
In Australia, Western Australia’s advancement to 6th globally on the Investment Attractiveness
Index and 3rd on the Best Practices Mineral Potential Index highlights both its strong policy
framework and significant geological potential. The improved rankin gs align with IsoEnergy’s
strategic expansion into Western Australia with the Company’s planned acquisition of Toro Energy
Limited announced on October 12, 2025. Additionally, IsoEnergy holds exploration projects in
South Australia and Queensland, ranking 4th and 13th, respectively.
The Fraser Institute’s Annual Survey of Mining Companies is widely regarded as a benchmark
assessment of global mining investment competitiveness. The Investment Attractiveness Index
combines mineral potential and policy factors, while the Best Practices M ineral Potential Index
evaluates geological prospectivity under ideal policy conditions.
