IsoEnergy Provides 2025 Athabasca Basin Exploration Update and Prepares to Launch Winter Exploration Programs Including Drilling at Larocque East

<article>
    <h2>IsoEnergy Updates 2025 Athabasca Basin Exploration Plans and Prepares Winter Drilling at Larocque East</h2>
    <p>IsoEnergy Ltd. (NYSE American: <strong>ISOU</strong>) has recently announced significant developments concerning its summer drilling activities at the Larocque East and Hawk projects in the Athabasca Basin. With a total of <strong>15,597 meters</strong> drilled across <strong>39 drill holes</strong> for the year, the company aims to build upon these encouraging results in its upcoming winter exploration programs.</p>

    <section>
        <h3>Drilling Activities and Results</h3>
        <p>During the summer drilling season, IsoEnergy completed <strong>9,561 meters</strong> in <strong>22 drill holes</strong> at Larocque East. This initiative has focused on expanding potential resources in the Hurricane deposit area while also exploring greenfield opportunities along the Larocque Trend. The latest results indicate strongly anomalous radioactivity and uranium geochemistry from both winter and summer drilling activities.</p>
        <p>At the Hawk project, an additional <strong>3,593 meters</strong> was drilled across four holes, adding to the ongoing exploration efforts aimed at uncovering uranium deposits. <em>Figure 1</em> and <em>Figure 2</em> illustrate these drilling locations and findings.</p>

        <h3>Key Highlights from Uranium Geochemistry Results</h3>
        <ul>
            <li><strong>LE25-194:</strong> Intersected <strong>0.872%</strong> U3O8 over <strong>0.5 meters</strong>, averaging <strong>0.313%</strong> U3O8 from basal sandstone.</li>
            <li><strong>LE25-207:</strong> Intersected <strong>1.61%</strong> U3O8 over <strong>0.5 meters</strong> directly above the unconformity.</li>
            <li><strong>LE25-202:</strong> Documented <strong>1.05%</strong> U3O8 over <strong>0.5 meters</strong>, indicating the strongest uranium intersection outside the Hurricane area.</li>
        </ul>
        <p>The above highlights reaffirm the prospectivity of the Larocque Trend, particularly in areas identified as highly favorable for uranium geology.</p>

        <h3>Future Exploration Plans</h3>
        <p>IsoEnergy is actively planning its upcoming winter drilling program at Larocque East, targeting <strong>5,200 meters</strong> across <strong>13 new holes</strong>. This drill program is designed to leverage the findings from both winter and summer explorations to establish precise drill targets for 2026. Additionally, extensive geophysical surveys are scheduled for various other projects, including Evergreen, East Rim, Ranger, Trident, and Hawk.</p>
        <p>Ms. Misty Urbatsch has been appointed as Vice President of Strategy and Commercial, bolstering IsoEnergy's management team with her robust background in uranium exploration and marketing, particularly within the Athabasca Basin.</p>
