Odyssey Gold Uncovers High-Grade Extensions at Tuckanarra Project

Strong Drilling Momentum at Tuckanarra

Odyssey Gold Limited (ASX – ODY) has announced excellent progress from its 2025 reverse circulation (RC) drilling program at the Tuckanarra Gold Project in Western Australia’s Murchison Gold District. The company’s recent drilling has intersected significant gold mineralisation, reinforcing confidence in the project’s shallow open-pit resources and revealing promising extensions between the Cable and Bollard pits.

The Tuckanarra Project currently hosts a Mineral Resource of 5.14 million tonnes at 2.5 grams per tonne (g/t) gold, equating to approximately 407,000 ounces. Recent drilling results include high-grade intersections such as 7 metres at 8.3 g/t, 18 metres at 4.3 g/t, and 2 metres at 10.3 g/t gold, demonstrating both continuity and grade potential within the resource envelope.

Targeting Electromagnetic Conductors and Sulphide Zones

A key highlight of the program has been the successful targeting of versatile time electromagnetic (VTEM) anomalies, which have identified sulphide mineralisation in all drilled targets. These sulphide zones, predominantly pyrrhotite with minor chalcopyrite, are associated with gold mineralisation and provide compelling exploration vectors for resource growth. Notably, drilling between the Cable and Bollard deposits has intersected mineralisation outside current resource boundaries, suggesting potential for expanding the mineralised footprint.

Drilling has also focused on infill and extensional targets within the Cable area, aiming to upgrade Inferred Resources to the Indicated category. The company’s systematic approach includes replicating historic drilling at tighter spacings and targeting multiple mineralisation styles, including quartz veining and sulphide replacement zones.

Historic Tailings Dams Show Economic Potential

In addition to primary mineralisation, Odyssey has sampled historic tailings dams at Tuckanarra and the nearby Trilby site. Auger sampling and metallurgical testwork indicate average gold grades around 1.2 g/t with cyanide recoveries averaging 82%, suggesting these tailings could represent a supplementary resource. The company plans further drilling and metallurgical studies to better define the tailings’ economic viability and support future processing strategies.

Advancing Towards Mining Studies

Odyssey’s executive director, Matt Syme, emphasised the positive implications of the drilling results for the project’s mining prospects. The company is progressing mining studies and metallurgical testwork, including grind optimisation and gravity separation, to underpin development plans. With ongoing drilling continuing to deliver encouraging results, Odyssey is well positioned to refine its resource base and advance towards potential production.

While some assay results remain pending, the overall drilling campaign has reinforced the geological model and highlighted multiple avenues for resource growth. The integration of historic data with new drilling and geophysical targeting is proving effective in unlocking the project’s potential.
