Wildfire halts IsoEnergy (NYSE American: ISOU) Larocque East drilling, 8,000 m program still on track
Rhea-AI Filing Summary
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.

Exhibit 99.1
IsoEnergy Provides Update on Wildfire Activity Near Larocque East Project, Athabasca Basin
TORONTO, June 29, 2026 /CNW/ - IsoEnergy Ltd. ("IsoEnergy", or the "Company") (NYSE American: ISOU) (TSX: ISO) provides the following update regarding wildfire activity in the vicinity of its Larocque East project (the "Project") in northern Saskatchewan. A wildfire, believed to have been caused by lightning, is currently burning in the vicinity of the Project. While the fire is not currently posing a direct threat to the Project site, the Saskatchewan Public Safety Agency ("SPSA") has advised that conditions are too dangerous for exploration work to proceed.
As advised by the SPSA, IsoEnergy has completed an orderly evacuation of most of its field personnel from the Project and has temporarily suspended exploration activities. Based on current guidance from the SPSA, personnel could remain away from the Project for up to one week, subject to changing wildfire conditions. Three contractors remain at the camp to operate pumps and sprinkler systems as a precautionary measure to help protect site infrastructure. Should the wildfire pose a direct threat to the camp, these personnel will be evacuated immediately in accordance with established safety protocols. The safety of the Company's employees and contractors remains its highest priority.
The Company confirms that all personnel have been accounted for and no injuries have been reported. As part of the evacuation, crews have implemented precautionary measures to help protect the camp, drill core storage and equipment where it is safe to do so. The Company is also working closely with the SPSA and is seeking confirmation regarding measures to protect Project infrastructure while access to the site remains restricted.
IsoEnergy continues to monitor the situation in coordination with the SPSA and will provide further updates as warranted. Exploration activities will resume once authorities determine it is safe to return to site. Based on current productivity and a typical summer drill season, a one-week evacuation should not impact the Company's ability to complete the current 8,000 metre drill program.
