Odyssey defines new high-grade hanging-wall vein at Tuckanarra’s Cable deposit

25 September 2025 | Perth, WA – Odyssey Gold (ASX: ODY) has outlined a new mineralised vein ~50m west of the current Cable Mineral Resource at its Tuckanarra Gold Project, with fresh RC results highlighting shallow, high-grade potential inside existing pit shells.

Key results – Cable West hanging-wall (new structure)

• 20m @ 7.1g/t Au from 47m, including 10m @ 12.9g/t from 54m (CBRC0199)
• 7m @ 2.0g/t from 36m (CBRC0202)
• 11m @ 0.7g/t from 34m (CBRC0197)
• Previously in this program: 7m @ 2.2g/t from 15m (CBRC0175)
• The structure is now traced over ~300m (150m in new RC plus ~150m south in historical AC/RAB). Portions sit within current pit optimisations, offering near-term growth options.

Cable infill – supporting the resource upgrade

• 22m @ 2.8g/t from 6m (CBRC0179)
• 9m @ 4.7g/t from 44m, including 2m @ 18.6g/t (CBRC0177)
• 15m @ 2.3g/t from 38m (CBRC0182)
• 11m @ 2.3g/t from 111m (CBRC0193)

Executive Director Matt Syme said the result west of the existing MRE “highlights the potential to find additional shallow resources within the existing optimisations and to grow the footprint of mineralisation west towards the historic Trilby Mine.” Follow-up work will target the 1km-long Trilby–Anchor vein corridor parallel to Cable–Bollard–Highway.

Context & next steps

• Cable MRE: 0.69Mt @ 2.3g/t Au for 123koz; Tuckanarra global MRE: 5.14Mt @ 2.5g/t for 407koz (including 2.25Mt @ 3.9g/t for 283koz >2.0g/t).
• More RC assays are pending. Planning is underway to infill Highway, Bollard, Cable and Maybelle to Indicated, and to systematically test the Anchor–Trilby structures for additional shallow resources.
