Could Cullen’s Find Bulk Gold Potential Reshape Mangaroon’s Outlook?

Breakthrough Drilling at Cullen’s Find

Dreadnought Resources has announced a promising development from its Mangaroon Gold Project in Western Australia, revealing thick, near-surface gold intercepts from a recent reverse circulation (RC) drilling program at Cullen’s Find. This marks the first drilling activity at the site since 1986, when a small shallow program returned high-grade but narrow gold veins. The new results, however, suggest the presence of more extensive bulk gold mineralisation within a sheared sediment package.

Of the eight holes drilled across a 400m by 300m gold-in-soil anomaly along the Minga Bar shear zone, seven returned gold mineralisation. Notable intercepts include 24 meters at 0.4 grams per tonne (g/t) gold from surface, including a higher-grade 3 meters at 2.2 g/t from 9 meters, and 17 meters at 1.1 g/t from 23 meters. These thick intercepts are the most substantial recorded to date at Cullen’s Find, indicating potential for larger-scale gold deposits beyond the historically known narrow veins.

Strategic Follow-Up and Broader Exploration

To better understand the structural controls on mineralisation, Dreadnought plans to twin the key hole CFRC001 with diamond drilling commencing imminently. This will provide critical geological orientation to guide future drilling efforts. Additionally, assays from 1-meter split samples, expected in December 2025, may refine grade estimates within these thick mineralised zones.

The Cullen’s Find discovery is part of a broader exploration campaign at Mangaroon, which includes approximately 75 RC holes targeting multiple prospects such as Star of Mangaroon, Pritchard’s Well, Steve’s Reward, Midday Moon, and Midnight Star. The company is also awaiting assay results from these areas, alongside ongoing soil sampling programs that have collected around 2,700 samples.

Context Within Mangaroon’s Growing Portfolio

Mangaroon is a large-scale project covering roughly 5,000 square kilometers in the Gascoyne region, with a focus on orogenic gold systems along major shear zones. Dreadnought’s strategy involves transforming into a self-funded explorer, leveraging a high-grade open pit at Star of Mangaroon with outsourced funding and processing to reduce reliance on market capital.

The project also hosts critical minerals prospects, including rare earth element resources at the Yin Ironstone Complex and Gifford Creek Carbonatite, as well as nickel-copper-PGE mineralisation under a farm-in agreement with Teck Resources. This diversified portfolio positions Dreadnought to capitalize on multiple commodity markets.

Looking Ahead

With thick gold intercepts at Cullen’s Find opening new exploration avenues, Dreadnought is poised to advance its understanding of the mineralised system through diamond drilling and detailed assay results. The company’s ongoing work across Mangaroon’s multiple prospects, combined with resource upgrades and metallurgical studies, will be critical to defining the project’s economic potential.
