Star of Mangaroon Yields 7m at 46.7 g/t Au in Latest Dreadnought Drilling
Dreadnought Resources has reported outstanding high-grade gold intercepts from recent infill drilling at the Star of Mangaroon, poised to significantly enhance the project’s resource and economics. With further assays pending and a new drilling campaign imminent, the Mangaroon Gold Project is gaining momentum.
- 16 additional infill RC holes yield shallow, thick, high-grade gold intercepts
- Notable results include 7m at 46.7 g/t Au and 12m at 20.6 g/t Au
- Current resource stands at 23,300oz at 12.8 g/t Au, with upgrade expected
- Next drilling program to start early September 2025 targeting multiple prospects
- Comprehensive work plan outlined through mid-2026 including mining and processing
Strong Infill Drilling Results at Star of Mangaroon
Dreadnought Resources has announced a series of impressive assay results from its ongoing reverse circulation (RC) drilling program at the Star of Mangaroon gold deposit in Western Australia’s Gascoyne region. The latest batch of 16 infill holes, totaling nearly 1,200 metres, has delivered shallow, thick, and notably high-grade gold intersections. Highlights include a standout 7 metres grading 46.7 grams per tonne (g/t) gold starting from just 27 metres depth, and an even richer 2-metre segment within that interval at 103.8 g/t Au.
Other significant intercepts include 12 metres at 20.6 g/t Au from 3 metres depth and 3 metres at 65.1 g/t Au from 93 metres. These results build on previous drilling successes at the site, reinforcing the deposit’s reputation for shallow, high-grade mineralisation that is amenable to open-pit mining.
Implications for Resource and Project Economics
The current Mineral Resource estimate for Star of Mangaroon stands at approximately 23,300 ounces of gold at an average grade of 12.8 g/t. The new drilling results are expected to materially upgrade this resource, particularly given the high proportion of indicated classification (83%) and the shallow nature of the mineralisation. This upgrade is anticipated to positively influence the mine plan and overall project economics, potentially accelerating development timelines and enhancing the project's value proposition.
Dreadnought’s Managing Director, Dean Tuck, emphasized the significance of these results, noting that the infill drilling has delivered “stand out results” that will feed into an updated resource and mine plan. The company plans to complete an upgraded resource estimate and mine study promptly after receiving assays from the remaining 14 holes, expected in September 2025.
Broader Exploration and Development Strategy
Beyond Star of Mangaroon, Dreadnought is preparing to commence a new RC drilling program in early September 2025. This campaign will not only extend drilling at Star of Mangaroon but also follow up on encouraging results from nearby prospects such as Steve’s Reward and Lesgo, as well as test new targets across the Mangaroon Gold Project.
The company has laid out a detailed work plan extending through mid-2026, encompassing resource upgrades, mine planning, processing agreements, and the commencement of production. This phased approach reflects Dreadnought’s strategy to transition into a self-funded explorer, leveraging third-party partnerships for funding, haulage, and processing to reduce capital reliance while focusing on discovery and resource growth.
Robust Geological and Analytical Framework
The announcement also provides comprehensive details on the geological setting, sampling techniques, and quality assurance protocols underpinning the drilling program. Assays were conducted by ALS Laboratories using photon assay methods, with rigorous QAQC measures including duplicates, blanks, and certified reference materials. The drilling was designed to intersect mineralised lodes at near-perpendicular angles, enhancing confidence in the representativity of the results.
Importantly, the mineralisation remains open to the north and at depth, with plans for additional drilling to test these extensions. The Star of Mangaroon deposit lies within a large-scale gold system along the Mangaroon Shear Zone, a region with multiple historical workings but limited modern exploration until Dreadnought’s recent consolidation and systematic programs.
Bottom Line?
As Dreadnought advances its drilling and resource updates, the Star of Mangaroon project is shaping up as a compelling high-grade gold opportunity in WA’s underexplored Gascoyne region.
Questions in the middle?
- How will the pending assays from the remaining holes influence the final resource upgrade?
- What are the timelines and terms for the processing and haulage agreements critical to project economics?
- Can Dreadnought replicate these high-grade results at nearby prospects like Steve’s Reward and Lesgo?
