Dynamic probes deep gold-copper targets near Widgiemooltha

Dynamic Metals has stepped up the pace of exploration at its Cognac West prospect near Widgiemooltha in Western Australia, launching a four-hole diamond drilling program to follow up gold and copper mineralisation identified in an earlier reverse circulation (RC) drill campaign.

The drill bit will test deeper extensions and key structural positions within the system, allowing the company to collect geological information that could help unlock the broader mineralised architecture.

Notably, the work has attracted financial backing from the West Australian Government’s Exploration Incentive Scheme, which has awarded the up to $175,000 in co-funding for drilling costs.

The prospect sits in a structurally complex corridor where secondary structures wrap around a late felsic intrusion 500 metres east of a major regional feature known as the Republican Thrust. This formation has long intrigued geologists, attracting intermittent exploration activity ever since the 1970’s.

However, much of that early exploration was shallow and incomplete, often limited to gold assays only. Encouragingly, Dynamic’s recent work appears to be paying dividends, piecing together a more coherent geological picture.

The company ran an extensive soil sampling program across the prospect two years ago, which helped define several higher-grade zones returning more than 100 parts per billion (ppb) gold.

Geological mapping and rock chip sampling also produced some eye-catching numbers, including assays as high as a ridiculous 2040 grams per tonne (g/t) gold alongside other strong results of 53.1g/t and 8.95g/t gold.

Those surface results were fed into the company’s geological model, generating a series of drill targets across two priority areas known as Anomaly A and Anomaly B.

Reverse circulation drilling began testing those targets last year. The first phase involved drilling 32 holes up to 150m deep, for a total of 4800m. Data from that work was then incorporated into the exploration model before a follow-up campaign of 19 additional RC holes.

The drilling confirmed Dynamic was clearly onto a mineralised system. The drill bit returned several tantalising gold intercepts, including 8m grading 2.78g/t gold from 60m, with a higher-grade core of 4 metres going just over 5g/t. Other hits include 4 metres at 1.66g/t gold and broader zones such as 24 metres averaging 0.29g/t gold.

While those intercepts were promising, the company says diamond drilling will provide the critical detail needed to better understand the geology at depth.

Once drilling is complete, the recovered core will undergo detailed logging and sampling before being sent for laboratory analysis. The first assay results from the diamond program are expected around May. Those results will then be fed back into the geological model to pinpoint targets for future drilling across Cognac West.

The (diamond drilling) program, supported by the WA Government’s Exploration Incentive Scheme, will allow us to test the deeper geological architecture of the system and significantly improve our understanding of the mineralised structures identified to date.

Dynamic’s broader Widgiemooltha project covers 800 square kilometres in one of Western Australia’s most storied mineral provinces, positioned between Norseman and Kambalda. The region has produced gold for well over a century and hosts several multi-million-ounce deposits alongside established mining infrastructure.

Elsewhere, the company is busy trawling through the data from a recent first-pass soil sampling program at its Leinster gold project in WA’s northern Goldfields, having defined a coherent gold-in-soil anomaly at its Risdon prospect.

Meanwhile, regional soil sampling has wrapped up at the company’s nearby Lady Jane project to test structural corridors linked to the Ida fault system and extend historical gold anomalies near the lucrative Zuleika Shear, with assay results pending.

The company has also stepped into the critical minerals arena after applying for exploration licences over the historic Meentheena fluorite field 60km east of Marble Bar in WA’s Pilbara.

First discovered in the 1970’s, the field hosts more than 100 fluorite veins up to 2m wide and 200m long, with historical grades exceeding 97 per cent calcium fluoride. However, it has never been commercially developed.

With the diamond rig now operating at Cognac West and new targets steadily emerging across its broader portfolio, Dynamic appears to be methodically stacking the geological odds in its favour.

If the deeper drilling confirms stronger mineralisation beneath the earlier hits, the company could quickly elevate Cognac West from an intriguing prospect into one of the more compelling emerging gold stories in the Widgiemooltha district.
