IsoEnergy Ltd. SEC Filings

IsoEnergy Ltd., a uranium exploration and development company with projects in Canada, the United States and Australia, advanced multiple 2026 programs, including 6,804 metres of winter drilling at the Larocque East Hurricane deposit, follow-up drilling at the Dorado joint venture, and drilling plus a 2,100‑ton bulk sample at the Tony M Mine in Utah. On June 25, 2026 it acquired Toro Energy, issuing 4,403,296 shares for total consideration of $75,278,817, adding the Wiluna uranium project in Western Australia.

The company remains pre‑revenue and reported a net loss of $6,689,958 for Q2 2026 and $8,192,733 for the first half, driven mainly by higher share‑based compensation and other general and administrative costs. Exploration and evaluation spending reached $11,815,895 in the first six months. Despite losses, IsoEnergy held cash and cash equivalents of $122,865,833 and adjusted working capital of $160,889,782 as of June 30, 2026, after raising $82.5 million in January equity financings. A base shelf prospectus allows offerings of up to $250 million over 25 months and an at‑the‑market program of up to $50.0 million, which, together with existing cash, management indicates fully fund planned exploration and pre‑development activities through the end of 2026.

IsoEnergy Ltd. released its Sustainability Report for the year ended December 31, 2025, covering operations across Canada, the U.S. and Australia. The report describes how the company integrates environmental stewardship, Indigenous and community partnerships, workforce development and governance into its growing uranium portfolio as it advances from exploration toward potential production.

The company highlights strengthened environmental programs, expanded Indigenous partnerships, increased local employment and procurement, and enhancements to its leadership team and governance framework. IsoEnergy notes that the commencement of trading on the NYSE American was an important 2025 milestone and continues to advance the Larocque East project in Canada’s Athabasca basin, home to the Hurricane deposit, described as the world’s highest-grade indicated uranium mineral resource. It also holds permitted past-producing uranium and vanadium mines in Utah on standby with a toll milling arrangement in place.

IsoEnergy Ltd. has resumed its summer drilling program on the Hurricane South Trend at the Larocque East uranium project in Canada after a temporary wildfire-related suspension. Four of a planned 20 drill holes have been completed and each intersected mineralization, including a standout interval averaging 11,075 cps over 3.5 m, with a peak of 43,160 cps over 0.5 m, confirming continuity of the newly identified L Fault Zone.

The program targets 8,000 m of diamond drilling in up to 20 holes focused on expanding the Hurricane deposit, which hosts a current Mineral Resource of 48.6 Mlb U3O8 at 34.5% U3O8 Indicated and 2.7 Mlb U3O8 at 2.2% U3O8 Inferred. IsoEnergy has also expanded and consolidated its land position in the eastern Athabasca Basin, staking approximately 61,830 hectares and optioning a further 31,293 hectares, bringing its total land access in the region to about 344,812 hectares.

IsoEnergy Ltd. reports that a lightning-caused wildfire is burning near its Larocque East uranium exploration project in northern Saskatchewan, prompting a temporary halt to field work.

The Saskatchewan Public Safety Agency advised that conditions are too dangerous for exploration, so IsoEnergy has evacuated most personnel and suspended activities. Three contractors remain at camp to run pumps and sprinklers to help protect infrastructure, with immediate evacuation planned if the fire threatens the site.

The company states all personnel are accounted for and uninjured, and precautionary steps have been taken to safeguard the camp, drill core storage and equipment. Based on current guidance and typical summer productivity, IsoEnergy believes a one-week evacuation should not affect completion of its current 8,000 metre drill program at Larocque East.

IsoEnergy Ltd. has completed its previously announced acquisition of Toro Energy Limited through a court-approved scheme of arrangement in Australia. IsoEnergy acquired all Toro shares it did not already own and issued approximately 4,359,568 new IsoEnergy common shares to former eligible Toro shareholders at an exchange ratio of 0.036 IsoEnergy share for each Toro share. Toro’s shares were suspended from trading on the ASX on June 16, 2026 and are expected to be removed from the ASX official list on or about June 26, 2026. IsoEnergy highlights the addition of the Wiluna Uranium Project as a key asset complementing its existing Hurricane project and other uranium holdings in Canada, the U.S. and Australia.

IsoEnergy Ltd. has started its 2026 summer exploration program at the Larocque East project in Canada’s eastern Athabasca Basin. The campaign includes about 8,000 metres of diamond drilling in up to 20 holes, mainly targeting the Hurricane South Trend.

The Larocque East project hosts the Hurricane deposit, with a current mineral resource of 48.6 million pounds U₃O₈ at 34.5% U₃O₈ indicated and 2.7 million pounds U₃O₈ at 2.2% U₃O₈ inferred. Recent winter 2026 drilling intersected high-grade zones such as 4.21% U₃O₈ over 3.5 metres in hole LE26-248, and the new program aims to expand mineralization along strike while advancing targets across other eastern Athabasca projects.

IsoEnergy Ltd. reported that shareholders approved all items at its annual general meeting, including the election of six directors and the re-appointment of KPMG LLP as auditor. Turnout was strong, with 38,225,097 common shares represented, equal to 63.05% of shares outstanding on the record date.

The company also provided an update on its proposed acquisition of Toro Energy Ltd. Toro shareholders approved the scheme of arrangement, with 92.89% of votes cast in favour. The transaction still requires Federal Court of Australia approval and remaining conditions to be met, with effectiveness targeted for June 16, 2026 and implementation expected on June 25, 2026.

Queen's Road Capital Investment Ltd. filed an amendment on a Schedule 13G disclosing beneficial ownership of 2,665,480 common shares of IsoEnergy Ltd., representing 4.82% of the class as of 03/31/2026.

The filing lists sole voting and dispositive power over the 2,665,480 shares and classifies the holding as "Ownership of 5 Percent or Less of a Class." The form is signed by Alex Granger on 05/11/2026.

IsoEnergy Ltd. reported new assay results from its 2026 winter drilling at the Larocque East project in Canada, confirming high-grade uranium mineralization along the Hurricane South Trend. Highlights include up to 4.21% U3O8 over 3.5 m, including 11.6% U3O8 over 1.0 m in hole LE26-248 within a reinterpreted fault zone.

The Hurricane deposit hosts a current Mineral Resource of 48.6 Mlb U3O8 at 34.5% U3O8 Indicated and 2.7 Mlb U3O8 at 2.2% U3O8 Inferred. Mineralization occurs at about 325 m depth and lies roughly 40 km from the McClean Lake mill, supporting potential future development options. The company noted that operations at Larocque East are not currently impacted by northern Saskatchewan flooding.
