Structural Uncertainties Persist Despite Encouraging Vulcan Drilling Results

Enterprise Metals has reported encouraging drilling results from its Vulcan Prospect in Western Australia, revealing significant gold mineralisation and evidence of a substantial copper-zinc-gold system. The findings support ongoing exploration efforts backed by government funding.

  • 16m at 1.26g/t gold intersected in shallow drilling
  • Evidence of deeply weathered copper-zinc-gold VMS system
  • Near-surface oxide copper mineralisation identified
  • WA Government grant covers nearly half of drilling costs
  • Further deeper drilling and geophysical surveys planned for 2026

Exploration Update at Vulcan Prospect

Enterprise Metals Limited (ASX, ENT) has released results from its 2025 drilling campaign at the Vulcan Prospect, part of the Doolgunna Project in Western Australia. The program, comprising nine reverse circulation (RC) holes and four air core (AC) holes, has delivered promising indications of gold and base metal mineralisation within a geological setting comparable to the nearby De Grussa deposit.

The highlight from the drilling was a 16-metre intersection grading 1.26 grams per tonne (g/t) gold starting at 40 metres depth, including a higher-grade 4-metre section at 3.57 g/t gold. This result not only confirms the historic soil geochemical anomaly but also suggests a significant gold mineralised zone extending over approximately 400 metres strike length.

Geological Insights and Mineralisation Style

Previously considered a shallow gold prospect with minor copper, the Vulcan Prospect is now interpreted as part of a deeply weathered volcanogenic massive sulphide (VMS) system. The presence of copper, zinc, and gold geochemical signatures within the Narracoota Volcanics of the Bryah Basin aligns with this interpretation. Notably, near-surface oxide copper mineralisation zones have been identified, although primary sulphide mineralisation in fresh rock remains to be fully delineated.

The drilling results have provided critical geological data that will inform the next phase of exploration. The company acknowledges that the structural controls on mineralisation are not yet fully understood, as some drill holes did not intersect primary mineralisation, highlighting the complexity of the system.

Support and Next Steps

Enterprise Metals received a grant of up to $90,000 from the Western Australian Government’s Exploration Incentive Scheme, covering nearly half of the planned drilling budget. This support underscores the strategic importance of the Vulcan Prospect within the region’s mineral exploration landscape.

Looking ahead, the company plans to undertake deeper RC and diamond drilling to follow up on the anomalous gold and base metal intersections. Complementary geophysical surveys, including downhole electromagnetic (DHEM) techniques, will be deployed to refine the geological model and target definition. Additionally, Enterprise Metals intends to explore other gold and copper targets within the tenement to expand its resource potential.

These ongoing efforts reflect a methodical approach to unlocking the Vulcan Prospect’s potential, with the possibility of a major VMS deposit at depth driving investor interest and regional exploration momentum.

Bottom Line?

Enterprise Metals’ Vulcan drilling results mark a significant step forward, but the true scale of mineralisation remains to be revealed through deeper exploration.
