TORONTO, Feb. 27, 2026 /PRNewswire/ – 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 tier 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, the 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 producing 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 rankings 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 Mineral Potential Index evaluates geological prospectivity under ideal policy conditions.
The summary of the Survey contained herein is subject to all of the assumptions, qualifications and procedures set out in the Survey and is qualified in its entirety by reference to the full text of the Survey.
