Meeka’s deeper gold at Turnberry: structural and resource cues for mine planners
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Meeka Metals has intersected visible gold about 300m below the current Turnberry underground resource in Western Australia’s Murchison region, signalling potential depth extensions to the orebody. Diamond hole 26TBRD010 hit visible gold at 632.8m down-hole within a broad shear zone containing chalcopyrite, pyrite, albite and magnetite, pointing to a sulphide-rich, structurally controlled system. Assays are pending, with results expected in September after detailed core logging, which will guide further deep drilling and resource modelling.
Technical Brief
- The new intersection occurs within a broad shear zone, indicating structurally controlled mineralisation continuity at depth.
- Sulphide assemblage includes chalcopyrite and pyrite, suggesting potential for associated Cu-Au sulphide ore rather than purely free-milling gold.
- Gangue minerals albite and magnetite point to sodic–iron alteration typical of orogenic lode systems in the Murchison.
- Detailed core logging prior to assaying will refine structural orientation, alteration intensity and sulphide distribution for modelling.
- For similar Western Australian orogenic deposits, such deep shear-hosted hits often trigger re-optimisation of underground mine designs and ventilation extents.
Our Take
The 632.8m downhole depth at Turnberry sits at the deeper end of recent Western Australian gold drilling in our database, implying Meeka Metals is actively testing for a larger, vertically extensive system rather than just incremental resource extensions.
Multiple recent items on Meeka’s Murchison gold project (including July 2026 drilling below the Turnberry Ore Reserve and May 2026 step-out work) suggest a consistent pattern of pushing mineralisation both down-dip and along strike, which could materially change underground mine design and ventilation planning in the Meekatharra region.
The association of gold with chalcopyrite, pyrite, albite and magnetite at Turnberry aligns with other greenstone-hosted systems in Western Australia in our coverage, indicating potential for more complex metallurgical behaviour and the need to lock in a flowsheet that can handle variable sulphide and alteration assemblages at depth.
