IsoEnergy Advances High-Grade Uranium Assets Amid Strategic Growth Initiatives

• IsoEnergy's Hurricane deposit in Saskatchewan holds 48.6Mlbs U₃O₈ at 34.5%—the world’s highest-grade indicated uranium resource.
• Past-producing, fully permitted U.S. uranium mines positioned for rapid restart under toll-milling agreement.
• ~$27M cash, ~$25M raised in Q1 2025, and $34M in equity holdings.
• 1-for-4 share consolidation supports planned NYSE American listing in Q2 2025.
• 2025 drill campaigns advancing Hurricane expansion and JV projects across 98,000+ ha in Athabasca Basin.

IsoEnergy is emerging as a leader in the uranium sector, combining a uniquely diversified asset base with one of the world’s highest-grade uranium deposits and a strong financial position to capitalize on the accelerating global shift to nuclear energy.

Boasting a substantial mineral endowment across Canada, the US, and Australia, IsoEnergy holds a total of 209 million pounds of indicated and 93 million pounds of inferred uranium resources, inclusive of historical estimates. Its flagship Hurricane deposit in Canada’s Athabasca Basin ranks as the highest-grade published indicated uranium resource globally, with 48.6 million pounds at an average grade of 34.5% U₃O₈​.

“IsoEnergy is a leading, globally diversified uranium company with substantial current and historical mineral resources in top uranium mining jurisdictions… providing near-, medium-, and long-term leverage to rising uranium prices,” the company stated in recent releases​​.

North American Production Potential with Permitted Mines in Utah

IsoEnergy’s US portfolio includes a suite of fully permitted, past-producing uranium and vanadium mines in Utah, including the Tony M, Daneros, and Rim projects—all within trucking distance to the White Mesa Mill under a toll milling agreement with Energy Fuels.

At Tony M, the company completed a successful reopening of the main decline in 2024 and initiated a comprehensive underground rehabilitation and mapping program. The mine hosts an indicated resource of 6.6 million pounds of U₃O₈ and an inferred resource of 2.2 million pounds, with significant upside through new underground exploration​.

“With a robust portfolio that includes the highest-grade published indicated uranium resource in Canada’s Athabasca Basin at our Hurricane deposit, past-producing US uranium mines in Utah... this move is essential to remaining competitive in the evolving uranium equity market,” said Philip Williams, CEO and Director, regarding the company’s recent application to list on the NYSE American​.

Strategic Capital Markets Growth & NYSE Listing Pathway

In early 2025, IsoEnergy closed a $20 million flow-through financing and a $6.25 million private placement with NexGen Energy, its largest shareholder, which maintains a 31.8% stake in the company. These funds will support exploration across Saskatchewan and Quebec and general corporate development​.

The company has also approved a 1-for-4 share consolidation to facilitate a planned listing on the NYSE American, expected in Q2 2025. This move is designed to expand IsoEnergy’s visibility and access to U.S. capital markets and institutional investors.

Expanding the World’s Highest-Grade Deposit at Hurricane

In Canada, IsoEnergy is aggressively drilling at its Hurricane deposit and across the Larocque East Project. A winter drill program of 2,800 metres across seven holes is underway to extend known mineralization and discover new high-grade lenses​.

In a broader regional play, the company also announced a 50/50 joint venture with Purepoint Uranium Group, covering 98,000 hectares in the eastern Athabasca Basin. The JV includes the Dorado, Aurora, and Celeste Block projects, and features a $5 million exploration budget for 2025, with drilling planned on high-priority targets along the Larocque Trend​.

“The 2025 Joint Venture program underscores our focus on advancing Dorado within the Larocque Trend, an area of exceptional potential,” said Purepoint CEO Chris Frostad​.

Portfolio Optimization & Global Positioning

IsoEnergy has also taken strategic steps to monetize non-core assets. In February, the company announced the completion of the sale of its Mountain Lake Property in Nunavut to Future Fuels, receiving equity consideration and royalty rights. The transaction boosts IsoEnergy’s exposure to the highly prospective Hornby Bay Basin while unlocking value for shareholders​.

With its diversified footprint, exposure to both near-term and long-term uranium production, and active exploration across Tier 1 jurisdictions, IsoEnergy is strategically aligned with the global push for secure, carbon-free baseload power.

Strategic Outlook

IsoEnergy is strategically positioned to benefit from the global resurgence in nuclear energy. With governments prioritizing energy security and clean baseload power, uranium demand continues to rise—and IsoEnergy offers a rare mix of high-grade resources, near-term production, and long-term optionality.

The flagship Hurricane deposit anchors its exploration growth, while fully permitted US mines offer rapid restart potential as market conditions improve. Backed by a strong balance sheet, recent financings, and a supportive shareholder base led by NexGen Energy, the company is well-capitalized to execute across its global portfolio.

A planned listing on the NYSE American and continued portfolio optimization further underscore IsoEnergy’s commitment to scale and shareholder value. As the uranium cycle strengthens, IsoEnergy stands out as a future-facing company ready to deliver at every stage of the supply chain.
