Strata Minerals has validated a significant gold mineralised system along a 9.5km corridor at its Zelica South Project in Western Australia, with rock chip samples hitting up to 11.78 g/t Au and silver anomalies supporting a fertile hydrothermal system.
- High-grade rock chips up to 11.78 g/t Au and 19.5 g/t Ag
- Widespread structurally controlled gold mineralisation over 6km strike
- Multiple parallel vein sets suggest stacked lodes
- New anomalous trends in underexplored western areas
- Plans for geophysical surveys and aircore drilling underway
Widespread Gold Mineralisation Validated Along 9.5km Corridor
Strata Minerals Limited (ASX:SMX) has confirmed extensive gold mineralisation across a 9.5-kilometre corridor at its 100% owned Zelica South Gold Project in Western Australia. The company’s recent rock chip sampling program collected 43 samples, returning assays up to 11.78 grams per tonne (g/t) gold and 19.5 g/t silver, validating historical prospects and demonstrating a structurally controlled gold system extending over a significant strike length.
These results reinforce the prospectivity of the Zelica South area, which forms part of a broader mineralised trend including the nearby Zelica Project. Geological mapping has revealed consistent shear-hosted structures with multiple parallel vein sets, indicative of stacked lodes, a feature that could support repeatable gold discoveries along the corridor.
Structural Insights and Hydrothermal Indicators
The geological team has improved understanding of the structural controls on mineralisation, confirming that gold is hosted within near-surface quartz veining and sheared mafic-ultramafic lithologies. Elevated silver and base metal anomalism, particularly in standout samples like SMZS048, suggests a fertile hydrothermal system typical of orogenic gold deposits. This could indicate proximity to the core of the mineralised system, potentially explaining the higher gold grades observed.
Historical workings at Eucalyptus Bore, Murphy Well, and West Nest were field-validated, with high-grade rock chips such as 11.78 g/t Au at Murphy Well and historical samples up to 39.6 g/t Au at West Nest confirming the area’s rich mineral endowment. The presence of vuggy quartz-carbonate-potassic alteration assemblages further supports the analogy between Zelica South and the established Zelica system 4.5km to the north.
Exploration Upside and Next Steps
Despite the promising surface results, exploration across the 6km strike of the corridor remains limited, with only 13 shallow historical drill holes completed. Strata plans to build on this foundation with a high-resolution magnetic geophysical survey to refine structural interpretations and identify drill targets.
Aircore drilling is prioritised to test the largely untested 6km interpreted gold corridor and underexplored western portions of the tenements. The company is also reviewing all historic datasets to better focus future drill programs. These activities align with Strata’s broader strategy to expand resources and support mining aspirations under its recently executed tribute mining agreement with BML Ventures, which provides a capital-light pathway to near-term production.
Geological Setting of the Zelica South Project
Located within the Eastern Goldfields Province of the Archean Yilgarn Craton, Zelica South sits on the west limb of the Eucalyptus Syncline, an asymmetrical fold structure intersected by the Celia Fault, a major regional deformation zone hosting multi-million-ounce gold deposits. The project area is dominated by ultramafic and mafic volcanic rocks with interflow sediments, intruded by granite plutons and Proterozoic dykes.
The structural complexity, including faulting and folding, combined with a veneer of colluvium and ironstone scree, has historically limited exploration. Strata’s recent work has begun to unravel this complexity, providing a clearer picture of mineralisation controls and enhancing confidence in the continuity of the gold corridor.
Bottom Line?
Strata Minerals’ rock chip results at Zelica South highlight a structurally robust gold system with multiple drill-ready targets, setting the stage for expanded exploration and resource definition in a highly prospective region.
Questions in the middle?
- Will upcoming aircore drilling confirm the continuity and grade of gold mineralisation along the 9.5km corridor?
- How will the planned geophysical survey refine structural models and influence drill targeting?
- Can the tribute mining agreement with BML Ventures accelerate the transition from exploration to production?
