• Results from infill drilling support Cable as the cornerstone of Odyssey's development strategy at Tuckanarra.
• High-grade mineralization confirmed beneath and adjacent to the existing Cable Mineral Resource Estimate.
• Updated Cable Mineral Resource Estimate and Stage 1 Scoping Study on track for release.

Odyssey Gold Ltd. has announced positive results from its ongoing resource growth and development drilling program at the Tuckanarra Gold Project in Western Australia. The program, which has completed over 190 holes and 15,000 meters since March 2026, aims to advance the Cable deposit toward development. Key highlights include high-grade gold intercepts, such as 5m @ 15.6g/t Au from 136m, confirming the continuity of mineralization and potential for resource growth. The Cable deposit, with an Indicated and Inferred Mineral Resource of 1.69Mt @ 2.3g/t Au for 123koz, is expected to form the foundation of Odyssey's staged development at Tuckanarra. The Company plans to complete an updated Mineral Resource Estimate for Cable, a Stage 1 Scoping Study, and a 20,000m drilling program, with follow-up drilling targeting further resource growth across the Tuckanarra Project.

The Company believes the current Mineral Resource Estimate represents only part of the broader opportunity within the Tuckanarra district and intends to continue systematic exploration alongside development studies.
