IsoEnergy Ltd. SEC Filings

IsoEnergy Ltd. reports progress on its U.S. uranium strategy, combining new drilling at the Flatiron Project in Utah with a completed bulk sample at the Tony M mine.

The 2026 program at Flatiron calls for seven additional rotary drill holes with core tails, totaling 11,000 feet. Flatiron covers 370 lode claims and two state leases, for 8,800 acres in the Henry Mountains district, near the past-producing Tony M mine and Energy Fuels’ Bullfrog deposit.

IsoEnergy has mined about 2,100 tons of mineralized material in a bulk sample at Tony M with no lost-time incidents. Data from this work will feed an NI 43-101 Preliminary Economic Assessment expected before year end. The company plans to send the material to Energy Fuels’ White Mesa Mill and is evaluating larger-scale ore sorting and slurry ablation, which previously recovered over 90% of uranium into 25–50% of the original mass in testing, potentially lowering future hauling and processing costs.

IsoEnergy Ltd. has entered into an Equity Distribution Agreement allowing it to issue and sell common shares with an aggregate offering price of up to C$50,000,000 through Virtu Canada Corp. and Virtu Americas LLC. Sales may be made from time to time on the TSX, NYSE American or other marketplaces as at-the-market distributions.

The program operates under IsoEnergy’s existing C$250,000,000 Canadian base shelf prospectus and related U.S. Form F-10 registration statement for various securities. The agents earn a 1.0% commission on gross proceeds, and net proceeds will be applied as described under “Use of Proceeds” in the prospectuses.

IsoEnergy Ltd. reports strong winter drilling results at its Larocque East project in Canada’s Athabasca Basin, targeting expansion of the high‑grade Hurricane uranium deposit. The 2026 program was expanded to 17 diamond drill holes totaling 6,804 metres after encouraging early results.

At Hurricane, one South Trend hole (LE26‑248) recorded 30,050 counts per second over 1.0 metre, within a broader 3.5‑metre interval averaging 11,275 cps at the unconformity around 330 metres depth. Multiple holes along the South and North trends intersected elevated radioactivity and intense alteration, supporting the potential for additional unconformity‑style uranium mineralization around the existing resource.

IsoEnergy Ltd. filed its annual report on Form 40-F for the year ended December 31, 2025, and highlighted strong rankings for its key uranium jurisdictions in the Fraser Institute’s 2026 Annual Survey of Mining Companies.

Saskatchewan ranked 3rd globally and hosts IsoEnergy’s Larocque East Project, including the Hurricane Deposit, described as the world’s highest grade published indicated uranium mineral resource at 48.6 Mlb U3O8 at 34.5% U3O8 indicated and 2.7 Mlb U3O8 at 2.2% U3O8 inferred. Western Australia advanced to 6th on the Investment Attractiveness Index and 3rd on the Best Practices Mineral Potential Index, aligning with IsoEnergy’s planned acquisition of Toro Energy Limited. The company also holds projects in Utah, South Australia and Queensland, providing exposure to multiple established uranium regions.

The Form 40-F, which includes the annual information form, audited financial statements and management’s discussion and analysis, is available on the SEC’s website and IsoEnergy’s website, with printed copies available on request.

IsoEnergy Ltd. files its annual report on Form 40-F for the fiscal year ended December 31, 2025, incorporating its Annual Information Form, audited consolidated financial statements and MD&A for the year.

The report states 54,928,896 common shares outstanding as of the close of the period. Management concluded that disclosure controls and procedures were effective, and no material change in internal control over financial reporting occurred. KPMG LLP is the independent registered public accounting firm.

IsoEnergy Ltd. completed a non-brokered concurrent private placement with NexGen Energy Ltd. for C$25,000,005. The company issued 1,666,667 common shares at C$15.00 per share. Proceeds are expected to fund continued development and exploration of its mineral properties and for general corporate purposes.

The financing was structured so NexGen can maintain its pro rata ownership at approximately 30% after a separate bought deal offering. The NexGen investment is treated as a related party transaction under MI 61-101, with IsoEnergy relying on exemptions because the deal value is below 25% of its market capitalization.

IsoEnergy Ltd. has completed a bought deal equity financing, selling 3,833,410 common shares at C$15.00 per share for gross proceeds of approximately C$57.5 million. The financing, led by a syndicate of underwriters including Stifel Canada, Canaccord Genuity Corp. and Jett Capital Advisors, LLC, included the full exercise of the over-allotment option. IsoEnergy plans to use the proceeds to continue developing and further exploring its uranium and vanadium mineral properties and for general corporate purposes. The company also expects to close a previously announced non-brokered concurrent private placement with NexGen Energy Ltd. on or about the same date.

IsoEnergy Ltd. is raising new equity through a C$50,001,000 bought deal financing, selling 3,333,400 common shares at C$15.00 each to a syndicate of underwriters. The company has also granted an over-allotment option for up to 500,010 additional shares at the same price, which would increase gross proceeds by C$7,500,150 to a total of C$57,501,150 if fully exercised.

Alongside this, IsoEnergy plans a non-brokered private placement of up to 1,666,666 common shares at C$15.00 per share with NexGen Energy Ltd. for up to C$25,000,000, allowing NexGen to maintain about a 30% ownership stake after the financing. IsoEnergy expects to use the combined proceeds to continue developing and exploring its uranium and vanadium mineral properties and for general corporate purposes, with closing targeted on or about January 27, 2026, subject to listing and regulatory approvals.

IsoEnergy Ltd. has started its 2026 winter diamond drilling program at the Larocque East project in Canada’s Athabasca Basin, which hosts the high-grade Hurricane uranium deposit. The campaign includes approximately 5,200 metres of drilling in up to 13 holes aimed at expanding the Hurricane resource and testing new greenfield targets up to three kilometres east along trend.

The Hurricane deposit currently has a Mineral Resource of 48.6 million pounds U3O8 at 34.5% U3O8 in the Indicated category and 2.7 million pounds U3O8 at 2.2% U3O8 in the Inferred category. Drilling will target North and South trends around Hurricane and a broader target area to the east where prior holes intersected uranium mineralization, leveraging existing infrastructure and relatively shallow mineralization around 325 metres depth.
