Odyssey Gold Strikes High-Grade Gold at Tuckanarra’s Highway Deposit

• Significant high-grade gold intersections at Highway deposit
• 20 RC holes (~2,600m) completed in current resource definition drilling
• Drilling confirms geological continuity and supports resource category upgrade
• Total Mineral Resource stands at 5.14Mt @ 2.5g/t Au for 407koz gold
• Ongoing drilling at Cable West Hanging Wall vein to extend mineralisation

Strong Drilling Momentum at Tuckanarra

Odyssey Gold Limited (ASX – ODY) has delivered another round of encouraging drilling results from its flagship Tuckanarra Project in Western Australia’s Murchison region. The company’s ongoing reverse circulation (RC) drilling program at the Highway deposit has intersected multiple zones of high-grade gold mineralisation, reinforcing the deposit’s potential and underpinning plans for a resource upgrade.

With 20 holes completed for approximately 2,600 metres in this phase, the drilling is focused on resource definition and infill, aiming to convert a significant portion of the existing Inferred Resource into the higher-confidence Indicated category. Noteworthy intercepts include 9 metres at 3.8 grams per tonne (g/t) gold from 37 metres, 14 metres at 13.6 g/t from 158 metres, and 26 metres at 2.3 g/t from 42 metres, demonstrating both oxide and fresh rock mineralisation continuity.

Geological Continuity and Resource Confidence

The drilling results closely align with the current Mineral Resource Estimate (MRE) models, confirming the geological interpretations and grade continuity required for advancing the project’s development studies. The presence of thick, high-grade supergene mineralisation near surface, extending to primary mineralisation at depth, supports the company’s confidence in the deposit’s scale and quality.

Importantly, the Highway deposit forms part of a broader mineralised trend extending over 2.3 kilometres, including the Cable and Bollard deposits. The current MRE totals 5.14 million tonnes at 2.5 g/t gold, equating to approximately 407,000 ounces of contained gold. A subset of higher-grade material above 2.0 g/t gold accounts for 2.25 million tonnes at 3.9 g/t for 283,000 ounces, highlighting the project’s economic potential.

Infrastructure and Next Steps

While the project advances, minor infrastructure considerations have emerged, including an estimated A$5 million cost to realign the Great Northern Highway and Telstra optic cables to accommodate open pit mining at Highway. Such adjustments are typical in Western Australian mining operations and are factored into ongoing feasibility assessments.

Drilling continues at the Cable West Hanging Wall vein following a recent high-grade intercept of 20 metres at 7.1 g/t gold, approximately 50 metres west of the current resource boundary. Further drilling and technical studies are planned to refine the Mineral Resource Estimate and support a forthcoming Scoping Study, which will provide a clearer picture of the project’s development pathway.

Looking Ahead

Odyssey’s Executive Director Matt Syme emphasised the significance of these results, noting the emerging quality and continuity of mineralisation at Highway. The company’s methodical approach to resource definition and study progression positions Tuckanarra as a compelling gold project in the Murchison, with potential for further resource growth and value enhancement.

Bottom Line?

Odyssey Gold’s latest drilling success at Tuckanarra sets the stage for a resource upgrade and critical development milestones.

Questions in the middle?

• How will the upcoming Mineral Resource Estimate revision impact project valuation?
• What are the timelines and key milestones for the Scoping Study completion?
• Could further drilling at Cable West significantly expand the resource base?
