Dynamic Metals has reported promising initial assay results from its first phase of drilling at the Cognac West prospect, revealing both broad low-grade and narrower high-grade gold mineralisation. The company is gearing up for a follow-up drilling campaign to further delineate these targets.
- 4,800m of Phase 1 RC drilling completed at Cognac West
- Significant gold intercepts including 8m @ 2.87g/t Au with 4m @ 5.37g/t Au
- Broad low-grade zones up to 44m @ 0.33g/t Au identified
- 1m interval assay results pending, expected by end of May 2025
- Phase 2 drilling planned to commence mid-May 2025 targeting refined anomalies
Exploration Progress at Cognac West
Dynamic Metals Limited (ASX:DYM) has announced encouraging results from its initial phase of reverse circulation (RC) drilling at the Cognac West prospect, part of the Widgiemooltha Project in Western Australia. The first phase involved 32 angled RC holes totaling 4,800 metres, designed to test subsurface gold mineralisation and refine geological models across two key target areas, Anomaly A and Anomaly B.
The drilling campaign has yielded promising assay results, notably at Anomaly B where broad zones of low-grade gold mineralisation were intersected, including a 44-metre interval grading 0.33 grams per tonne (g/t) gold. More strikingly, a narrower, higher-grade zone was identified with an 8-metre intercept averaging 2.87 g/t gold, including 4 metres at 5.37 g/t from 60 metres depth. These findings suggest the presence of a potentially significant mineralising system that warrants further investigation.
Refining the Geological Model
Dynamic Metals has leveraged multi-element geochemical assays to classify lithological units and enhance its targeting model. This approach has been instrumental in understanding the complex structural setting of Cognac West, which features second-order structures around a late felsic intrusion near the major Republican Thrust fault. Historic exploration in the area, dating back decades, was limited and often incomplete, making Dynamic’s systematic drilling and sampling efforts critical to unlocking the prospect’s potential.
At Anomaly A, drilling intersected a quartz vein mapped at surface, though initial results showed low gold grades within the weathered profile rather than fresh rock. This has prompted plans for targeted Phase 2 drilling to test down-dip extensions in fresh rock, aiming to better define the vein’s mineralisation potential.
Next Steps and Market Implications
Following the initial 4-metre composite sampling, Dynamic Metals has undertaken detailed 1-metre interval sampling on composites exceeding 0.1 g/t gold, with results expected by the end of May 2025. These finer-scale assays will provide greater resolution of the mineralisation profile and guide the upcoming Phase 2 drilling campaign, scheduled to start mid-May. This next phase will focus on expanding the known mineralised zones and testing structural features that may control gold distribution.
Managing Director Karen Wellman expressed confidence in the exploration methodology, highlighting the value of the initial drilling in refining the geological understanding and identifying high-grade zones. The company’s strategic approach and ongoing work position it well to advance the Widgiemooltha Project’s gold potential, potentially enhancing shareholder value as exploration progresses.
Bottom Line?
Dynamic Metals’ initial drilling success at Cognac West sets the stage for a critical follow-up phase that could redefine the project’s gold potential.
Questions in the middle?
- Will the pending 1m assay results confirm continuity and higher grades within the identified zones?
- How will Phase 2 drilling refine the understanding of structural controls on gold mineralisation?
- Could these results lead to a maiden resource estimate or attract joint venture interest?
