Dynamic Metals Extends Cognac West Gold Mineralisation to 300m Depth

Gold Found at Depth Beneath Cognac West

Dynamic Metals Limited (ASX:DYM) has extended the known gold mineralisation at its Cognac West prospect in Western Australia to approximately 300 metres below surface. The first assay results from a recent four-hole diamond drilling program reveal significant gold intercepts well beneath the shallow zones previously drilled at Anomaly B, confirming continuity of the mineralised system at depth.

This development is notable given the grades, while moderate, include intercepts such as 4 metres at 1.5 grams per tonne (g/t) gold, including 1 metre at 3.5g/t from 311 metres depth, and 1.5 metres at 2.5g/t including 0.6 metres at 4.3g/t closer to surface. These results demonstrate the system’s vertical extent and potential for a more substantial deposit than earlier understood.

Dynamic Metals’ Managing Director Karen Wellman highlighted the importance of these findings, stating the gold at depth “provides a strong foundation for the next phase of drilling” and supports the prospect of a broader mineralised system. The drilling program was designed to improve geological and structural understanding in a complex corridor, and the initial results validate targeting deeper zones similar to those exploited at nearby operations such as Higginsville and Junction gold mines.

Drilling Targets and Structural Insights

The diamond drilling campaign consisted of four holes totalling around 1,400 metres, focusing on priority zones within Anomalies A and B identified through previous soil geochemistry, rock chip sampling, and two phases of Reverse Circulation (RC) drilling in 2025. At Anomaly B, where the recent gold intercepts occurred, the drillholes tested both broad low-grade zones and higher-grade domains, including historic RC results of up to 8 metres at 2.87g/t gold.

Drill hole WDRD082, designed to test a VTEM geophysical conductor and depth extensions of known anomalism, intersected multiple gold intervals including 2 metres at 1.9g/t from 302 metres and 4 metres at 1.5g/t from 311 metres. The mineralisation is hosted within narrow felsic units amidst a broader dolerite sequence, where contrasts in rock rheology appear to have channelled mineralising fluids. Quartz-carbonate veining with pyrite is the primary host of the gold, consistent with shear-hosted deposits typical of the Yilgarn region.

Meanwhile, WDRD083, a diamond twin of a prior RC hole, intersected a strongly deformed zone with 0.6 metres at 4.3g/t gold from 62 metres, associated with sulphides and quartz veining, confirming a mineralised shear zone. However, this structure was not repeated at depth in this hole.

Pending Assays and Government Support

Assays from the remaining two diamond holes, which targeted magnetic anomalies near Anomaly A; a quartz vein system with surface rock chips grading up to a remarkable 2,040g/t gold; are still awaited. These results will be crucial to assessing the full potential of the prospect’s high-grade zones.

The program benefits from up to $175,000 in co-funding from the Western Australian Government’s Exploration Incentive Scheme, underscoring public sector support for advancing exploration in this historically prolific gold district. Dynamic Metals has previously secured this grant to underpin the diamond drilling campaign, reflecting confidence in the project’s prospectivity.

Dynamic Metals’ Widgiemooltha Project, encompassing Cognac West, spans approximately 800 square kilometres between Norseman and Kambalda. The region has a rich history of gold and nickel production and hosts multiple million-ounce gold camps. The company’s ongoing exploration efforts are focused on unlocking value across this highly prospective tenure.

The recent drilling and assay results build on the company’s earlier phases of RC drilling that identified broad zones of low-grade gold mineralisation and helped prioritise targets for follow-up. The current diamond drilling’s deeper focus aligns with exploration strategies at neighbouring mines, aiming to delineate vertically extensive mineralised systems that could underpin future resource growth.

As the remaining assay results come in and geological data from the diamond core is integrated, Dynamic Metals plans further drilling to test extensions of mineralisation at Anomaly B and refine its geological model. This evolving dataset will be pivotal in determining whether Cognac West can develop into a significant gold resource within the Widgiemooltha district.

Dynamic Metals’ recent diamond drilling program follows its earlier initiative to deepen understanding of gold-copper mineralisation at Cognac West, which was also supported by government co-funding and reported in March 2026. These efforts reflect a methodical approach to advancing one of the company’s most promising targets amid a competitive exploration landscape in Western Australia.
