Dynamic Metals has successfully extended the gold system at its Cognac West prospect to a depth of 300 metres, confirming that the mineralisation at its Anomaly B target is far more vertically extensive than previously thought.
The results from the company’s maiden diamond drilling program at its flagship Widgiemooltha project have provided a critical link, confirming the presence of gold mineralisation deep beneath the near-surface anomalism defined in earlier exploration.
Initial assay results from the diamond core included a standout intercept of 4 metres grading 1.5 grams per tonne(g/t) gold and featured a 1-metre sweet spot at 3.5g/t gold from 311m depth.
The same hole also produced 2m running at 1.9g/t gold from 302 metres, including a handy 0.8m at 3.1g/t gold. A further hole inked 1.5 metres at 2.5g/t gold from 60.9m, clocking a 0.6-metre slice at 4.3g/t gold.
Whilst initial grades from this deeper zone might appear moderate at first glance, the results are technically highly significant for Dynamic as they demonstrate that the gold system extends well below the limits of any prior drilling.
The company’s four-hole, 1400-metre diamond program represents the next stage of systematic exploration for Dynamic, following two phases of reverse circulation drilling completed in 2025.
These initial diamond drilling results confirm gold mineralisation at depth beneath previously defined shallow anomalism, representing an encouraging step forward for Cognac West. The identification of mineralisation at these depths supports the potential for a broader, vertically extensive system and provides a strong foundation for the next phase of drilling.
Those initial programs were instrumental in defining the Anomaly A and Anomaly B hotspots through a rigorous combination of soil geochemistry, high-grade rock chip sampling and systematic reverse circulation passes.
Dynamic’s 2025 work defined broad zones of low-grade gold across multiple targets, identifying Anomaly B as the priority zone for this deeper follow-up. The rationale for the current diamond program was to push beyond those shallow limits and provide the company with the detailed structural data required to untangle the site’s geological complexities.
Notably, the drilling at Cognac West is testing depths similar to those targeted by other gold-focused operations at nearby major mines in the Widgiemooltha district, including Westgold Resources’ 90,000-ounce-per-annum Higginsville mine. Dynamic says confirmation of gold at these depths supports the potential for a more substantial mineralised system lurking below the surface.
The West Australian government also threw its hat into the ring, backing the technical merit of the company’s program. The State stumped up $175,000 in co-funding through its exploration incentive scheme, enabling Dynamic to test its theory that the shallow mineralisation was merely the “smoke” from a much larger fire at depth.
Beyond Cognac West, Dynamic maintains a dominant land position in the Widgiemooltha region, covering 800 square kilometres, prospective for both gold and nickel. The company also holds a diverse portfolio of exploration assets across the state, including the Leinster and Meentheena projects, which are being explored for gold, lithium, and base metals.
The company says next steps involve the integration of these new results with existing datasets to refine the geological model. Additionally, assays for the final two diamond holes, which targeted geophysical anomalies around Anomaly A, are set to land any day. The zone previously yielded spectacular surface rock chip results of up to 2,040 grams per tonne gold.
With gold now confirmed at depth and more assay results on the way, Dynamic appears to be building a compelling case for a larger mineralised system potentially lurking under the surface at Cognac West.
