Dynamic Metals Limited’s latest Phase 2 drilling results at the Cognac West prospect confirm significant gold and copper mineralisation, highlighting a complex polymetallic system. The findings pave the way for refined exploration strategies incorporating new geophysical insights.
- Phase 2 drilling confirms gold and copper anomalism at Anomaly B
- Notable gold intercepts include 8m @ 2.78g/t Au and 4m @ 5.04g/t Au
- Copper assays reveal up to 5m @ 0.44% Cu with cobalt presence
- Petrological analysis identifies chalcopyrite and cobaltite, indicating mineral system complexity
- Reprocessing of airborne electromagnetic data underway to guide further drilling
Exploration Update at Cognac West
Dynamic Metals Limited (ASX, DYM) has released encouraging results from its Phase 2 reverse circulation drilling campaign at the Cognac West gold prospect, part of its Widgiemooltha Project in Western Australia. The drilling has confirmed the presence of both gold and copper mineralisation across a key target area known as Anomaly B, reinforcing the prospect’s potential as a polymetallic system.
The company reported significant gold intercepts, including an 8-metre section grading 2.78 grams per tonne gold, with a higher-grade 4-metre interval at 5.04 grams per tonne. These results build on earlier Phase 1 drilling that identified broad zones of gold anomalism. Copper assays also returned notable values, with up to 5 metres at 0.44% copper and associated cobalt, a critical metal, detected in the mineralised zones.
Complex Mineralisation and Geological Insights
Petrological studies have identified chalcopyrite and cobaltite minerals within the drill samples, suggesting a complex, multi-phase hydrothermal system. This polymetallic signature is significant as it indicates overlapping mineralising events, which could enhance the prospect’s economic potential beyond gold alone.
Geologically, Cognac West is structurally intricate, with mineralisation hosted in volcaniclastics near a late felsic intrusion. Historic exploration in the area has been limited and focused mainly on gold, making Dynamic Metals’ integrated approach; combining drilling, petrology, and geophysics; particularly valuable for refining the geological model.
Next Steps and Broader Exploration Strategy
Dynamic Metals is currently reprocessing historical airborne electromagnetic survey data to better understand a late-time conductive feature beneath Anomaly B. This geophysical work aims to clarify the structural controls and extent of mineralisation, informing the planning of follow-up drilling campaigns.
Beyond Cognac West, the company continues regional exploration across its Widgiemooltha Project, including soil sampling at the nearby Courvoisier gold prospect and planned drilling at Chalice South. These activities underscore Dynamic Metals’ commitment to advancing its portfolio of precious and critical metals projects in a highly prospective region.
Bottom Line?
Dynamic Metals’ latest results at Cognac West hint at a richer polymetallic system, setting the stage for targeted drilling and deeper geological understanding.
Questions in the middle?
- How will the reprocessed electromagnetic data influence the next drilling targets at Cognac West?
- What is the potential scale and grade continuity of the copper mineralisation relative to gold?
- Could the polymetallic nature of the system attract strategic partnerships or joint ventures?
