Isoenergy Ltd. Resumes Operations At Larocque East Project After Temporary Suspension IsoEnergy Ltd. has resumed summer drilling at the Larocque East project, which hosts the high-grade Hurricane deposit, in the eastern Athabasca Basin, Canada, following a temporary suspension and precautionary evacuation due to nearby wildfires. Approximately 2,100 m of drilling had been drilled across four completed holes and two in progress prior to the temporary suspension due to nearby wildfire, with two additional holes in progress. The company remained on track to complete the ~8,000 m, 20-hole summer program as planned. With the immediate fire risk abated, the company anticipated completing the 8,000 m summer drill program as designed. Announcement • Jun 30
Isoenergy Temporarily Suspends Exploration Activities and Evacuates Personnel At Larocque East Project Due to Wildfire IsoEnergy Ltd. provided an update regarding wildfire activity in the vicinity of its Larocque East project in northern Saskatchewan. A wildfire, believed to have been caused by lightning, was currently burning in the vicinity of the Project. While the fire was not currently posing a direct threat to the Project site, the Saskatchewan Public Safety Agency advised that conditions were too dangerous for exploration work to proceed. As advised by the Saskatchewan Public Safety Agency, IsoEnergy completed an orderly evacuation of most of its field personnel from the Project and temporarily suspended exploration activities. Based on current guidance from the Saskatchewan Public Safety Agency, personnel could remain away from the Project for up to one week, subject to changing wildfire conditions. Three contractors remained 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 would be evacuated immediately in accordance with established safety protocols. The Company confirmed that all personnel had been accounted for and no injuries had been reported. As part of the evacuation, crews implemented precautionary measures to help protect the camp, drill core storage and equipment where it was safe to do so. The Company was also working closely with the Saskatchewan Public Safety Agency and was seeking confirmation regarding measures to protect Project infrastructure while access to the site remained restricted. IsoEnergy continued to monitor the situation in coordination with the Saskatchewan Public Safety Agency and would provide further updates as warranted. Exploration activities would resume once authorities determined it was 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.
