IsoEnergy has completed mobilization for a 2026 surface rotary drilling program at its 8,800-acre Flatiron project in Utah’s Henry Mountains district, targeting the lowest sandstone unit of the Salt Wash Member. The seven planned drill holes totaling 11,000 feet build on three late-2025 holes and aim to follow up on historical exploration along the trend from the Tony M deposit.

The company mined approximately 2,100 tons of mineralized material from Tony M without any lost-time incidents, testing health and safety protocols, ground control, ventilation, drilling, blasting and grade control. This bulk sample provides operational data on mining rates, sequencing, dilution, equipment sizing, and costs to refine its production plans.

IsoEnergy is in final consultant selection for an NI 43-101 PEA expected before year-end and plans to deliver the bulk sample to the White Mesa Mill. Parallel testing of ore sorting and high-pressure slurry ablation demonstrated over 90% uranium recovery into reduced mass, potentially lowering future hauling and processing costs.
