Chalice Mining ceases to be substantial holder in Encounter Resources

Chalice Mining Limited and its group entities ceased to be a substantial holder in Encounter Resources Limited on November 6, 2025. This change occurred due to a dilution in Chalice's holding following the issuance of ordinary shares in Encounter Resources, specifically a placement. As a result, Chalice's relevant interest in Encounter Resources, which was previously 27,331,579 ordinary shares, was affected by the same amount.

Concurrently, William Robinson's substantial holding in Encounter Resources increased from 6.90% to 5.12% of voting power, despite a nominal increase in his shares from 27,285,889 to 28,385,889 votes. This apparent decrease in voting power is attributed to dilution from new share placements and the exercise of options. Robinson acquired 700,000 ordinary shares on November 2, 2023, for AUD 113,400, and another 400,000 ordinary shares on November 8, 2024, for AUD 88,800 through the exercise of options.
