Dundas Minerals has delivered high-grade gold assay results from 1m re-assays at its Rockland project near Kalgoorlie, validating a mineralised corridor extending over 2km from Capricorn through Rockland. The company is gearing up for extensive drilling to test depth extensions and linkages along this emerging gold system.
- 1m re-assays confirm high-grade gold shoots at Rockland
- Mineralised system extends over 2km from Capricorn to Rockland
- Significant intercepts include 1m at 20.35 g/t Au and multiple other hits
- Capricorn Mining Lease granted with drilling approvals pending heritage survey
- Follow-up drilling planned at Rockland, Capricorn, Aquarius, and connecting trend
High-Grade Gold Confirmed in Single-Metre Assays at Rockland
Dundas Minerals Limited (ASX:DUN) has sharpened the focus on its Rockland Gold Project with new single-metre assay results that confirm high-grade gold shoots within a broader mineralised corridor. These 1m re-assays refine previously reported 4m composite samples, revealing standout intercepts such as 1m at 20.35 g/t Au from 140m and other significant grades like 1m at 5.99 g/t Au. The results underpin Dundas’ interpretation of mineralised shoots hosted in a north-south structural system that extends for over 2km, linking Capricorn, Rockland, Aquarius, and Gemini prospects in the Kalgoorlie district.
Mineralised Corridor Extends with Open-Ended Potential
The mineralisation remains open both along strike and at depth, highlighting a substantial emerging gold system. Dundas plans follow-up drilling aimed at testing depth extensions at Rockland and exploring potential linkages toward Capricorn and Aquarius. The Capricorn Mining Lease has recently been granted, and Programmes of Work have been approved, with drilling set to commence following a heritage survey expected in early July. This lease hosts a previously reported Mineral Resource Estimate and remains open for further resource growth through extensional and infill drilling.
Drilling Strategy Targets Resource Expansion and Geological Confidence
Drilling at Capricorn will focus on areas identified by internal conceptual pit shell modelling that suggest limited drilling has constrained potential mining opportunities. While this modelling is preliminary and not a mining study, it serves as a drill-targeting tool to improve geological confidence. Additionally, a drilling program is planned between Rockland and Capricorn to test the mineralised corridor, supported by encouraging results from southern Capricorn drill lines, including intercepts of 3m at 9.14 g/t Au and 1m at 6.6 g/t Au.
The Aquarius prospect, situated immediately north of Rockland on the same structural corridor, has also returned high-grade results from earlier drilling but remains largely untested below shallow depths. Previous intercepts there include 3m at 10.2 g/t Au and 1m at 29.6 g/t Au, reinforcing the potential for further discoveries along this trend.
Technical Rigor and Sampling Methodology
Dundas employed reverse circulation (RC) drilling with 5-inch diameter face-sampling hammer bits, collecting 1m samples for photon assay to provide a high-resolution grade distribution. Sample recovery was generally good, with quality control measures including certified reference materials and field duplicates ensuring data reliability. Drillhole collars were surveyed with handheld GPS and downhole surveys conducted by gyro to maintain spatial accuracy.
The company cautions that reported intercepts are downhole lengths and true widths are not yet known, though they are interpreted to be close. The internal pit shell modelling used for drill targeting is preliminary and does not establish economic viability or represent a production target.
Positioning for Growth in a Prolific Gold District
Dundas’ portfolio in the Kalgoorlie district includes three advanced gold projects, Rockland, Capricorn, and Baden-Powell, all open-ended and near existing processing infrastructure. The recent assay results and granted mining lease at Capricorn position Dundas to advance its exploration and technical assessment aggressively. Follow-up drilling at Rockland and Capricorn, alongside testing the mineralised corridor to Aquarius, could unlock significant resource expansion in this historically prolific gold region.
Bottom Line?
Dundas is poised to leverage its granted Capricorn lease and high-grade Rockland assays with targeted drilling, but geological uncertainties and preliminary modelling mean investors should watch closely for how these programs translate into resource upgrades.
Questions in the middle?
- Will follow-up drilling confirm continuity and true widths of the high-grade shoots?
- How will the Capricorn resource model incorporate new assay data from ongoing drilling?
- What impact will heritage survey outcomes have on the timing and scope of drilling programs?
