Highlights

  • Black Oak air core drilling totalled 234 holes for 14,559 metres, with initial assays reported for 115 holes.
  • A reported intersection included 15 metres at 0.9 grams per tonne gold from 27 metres in ILAC0595.
  • The company described gold-bearing structures extending approximately 1.5 kilometres at Black Oak.
  • Assays from 119 additional air core holes were expected during November 2026.
  • Reverse circulation drilling was planned for November–December 2026 to test targets at greater depth.

Dreadnought Resources Ltd explores for gold and other minerals in Western Australia, including at its Illaara and Mangaroon projects. At Illaara, about 190 kilometres northwest of Kalgoorlie, the company is assessing a broad greenstone belt through staged drilling. Dreadnought Resources (ASX:DRE) reported on 2 November 2026 that its first batch of follow-up air core assays from the Black Oak prospect had identified further shallow gold mineralisation, with substantial laboratory results still outstanding. The findings inform the next exploration stage but do not establish a new mineral resource at Black Oak.

Black Oak Air Core Results Define Follow-Up Targets

The completed Black Oak programme comprised 234 air core holes over 14,559 metres. The initial release covered 115 holes and 6,554 metres, leaving 119 holes awaiting assays. The strongest reported intersection was 15 metres at 0.9 grams per tonne gold from 27 metres in hole ILAC0595, including 3 metres at 4.0 grams per tonne from 36 metres. These are downhole intersections rather than confirmed true widths.

Geological Continuity and Exploration Limits

Air core drilling is designed to test shallow rock and weathered material across relatively extensive areas. It can help identify structures for follow-up drilling, but isolated intercepts cannot determine a deposit’s economic potential. Dreadnought Resources (ASX:DRE) described a mineralised structure extending around 1.5 kilometres, open along strike and at depth. Its interpretation associates the gold with shearing between mafic-ultramafic volcanic rocks and sulphidic sediments.

Illaara Exploration Programme and Next Milestones

The Illaara project covers approximately 800 square kilometres and about 70 kilometres of greenstone strike. Dreadnought Resources (ASX:DRE) said first-pass air core drilling had examined only about one-tenth of the belt and identified 13 gold-mineralised corridors, with interpreted strike lengths ranging from approximately 1.5 kilometres to more than seven kilometres. Such regional targets are prospective exploration areas, not mineral resources or production forecasts.

For Black Oak, a reverse circulation rig was scheduled to commence discovery drilling between November and December 2026, with assays anticipated from December 2026 to February 2027. The company also expected remaining air core results in November and planned further air core work through December. At Metzke’s Find, diamond drilling results were expected in November, while resource and study work and subsequent approvals activity were planned for 2027. These are prospective milestones rather than completed outcomes.

Key Insights

Dreadnought Resources (ASX:DRE) has reported shallow gold intersections at Black Oak and identified a structure that warrants deeper testing. The principal near-term evidence will come from the outstanding 119 air core holes and the proposed reverse circulation programme. The size of the wider Illaara belt provides multiple exploration targets, but current Black Oak data do not establish continuity at Mining scale, an economic resource or a development timetable. Follow-up assays and geological interpretation will determine how the prospect advances.
