IsoEnergy begins 2025 exploration program in Utah

Executive Summary

• IsoEnergy Ltd. announced the start of its 2025 U.S. exploration program, beginning with 10 surface rotary holes (15,000 ft total) on the Flatiron claims in southeastern Utah.
• The program expands fieldwork at the Daneros and Sage Plain projects to better define sedimentary controls on uranium mineralization, supporting future drilling and potential production.
• IsoEnergy now holds an 8,800‑acre land package (370 lode claims + two state leases) in the Henry Mountains district, one of the largest contiguous positions in the area, positioning the company for near‑ and long‑term domestic uranium supply.

Key Details

• Flatiron Drilling Plan: 10 surface rotary holes with core tails, totaling ~15,000 ft, targeting the lowest sandstone unit of the Salt Wash member (primary host across the district).
• Land Position: 370 lode claims staked in 2024 plus two Utah state leases; total acreage now 8,800 ac.
• Historical Context: Flatiron sits on historic Plateau Resources drill targets from the early‑1980s that were never followed up due to low uranium prices.
• Geological Rationale: Target unit contains adequate reductant material and hydrogeologic setting for commercially viable uranium grades; low vanadium grades also anticipated.
• Additional Projects: Ongoing fieldwork at Daneros and Sage Plain (both past‑producing, standby mines) includes detailed mapping, measured sections, and analog modelling to define sedimentary frameworks and guide future geophysical surveys.
• Strategic Importance: Program aligns with growing U.S. interest in expanding the strategic uranium reserve and domestic supply security.
• Qualified Person: Dr. Dan Brisbin, P.Geo., Vice‑President Exploration (NI 43‑101 qualified).
