Dundas Confirms Gold Continuity at Rockland with Depth Extensions

Mining By Maxwell Dee 5 min read

Dundas Minerals has extended gold mineralisation at its Rockland project near Kalgoorlie, confirming a 1km strike length and improving grades at depth. The company plans follow-up drilling to test extensions and linkages to nearby Capricorn and Aquarius prospects.

  • RC drilling confirms 1km strike gold system at Rockland
  • Significant intercepts include 4m @ 4.54 g/t and 12m @ 1.22 g/t Au
  • Mineralisation open at depth with grades improving below oxide zone
  • Follow-up drilling planned to test corridor towards Capricorn and Aquarius
  • Option withdrawal from GTT Metals to focus on core Kalgoorlie assets

Drilling Confirms Continuity and Depth Potential at Rockland

Dundas Minerals Limited (ASX:DUN) has reinforced the significance of its Rockland Gold Project with assay results from a recent reverse circulation (RC) drilling program that confirmed continuity of gold mineralisation over approximately 1km strike length. The program, comprising 10 holes for 1,688m, intercepted broad zones of gold beneath and along strike from previous high-grade discoveries, including standout results of 4m @ 4.54 g/t Au from 140m and 12m @ 1.22 g/t Au from 172m (including 4m @ 3.13 g/t Au) in hole 26RKRC005.

These latest results support Dundas' interpretation of a large, north-south structural corridor hosting multiple lodes at Rockland, with mineralisation open both along strike and at depth. Notably, grades appear to increase below the oxide-supergene zone, with deeper fresh rock intercepts showing promising gold values. The deepest intercept to date, 4m @ 3.13 g/t Au, suggests the system strengthens at depth, a key factor for resource expansion and potential economic viability.

Strategic Corridor Links to Capricorn and Aquarius Prospects

Rockland sits within a granted Mining Lease approximately 40km north of Kalgoorlie, embedded in a mineralised corridor extending northwards through the Aquarius and Capricorn prospects. Dundas is preparing a Programme of Works (POW) to drill at Capricorn, where previous drilling returned encouraging results such as 3m @ 9.14 g/t Au, and to test the largely untested zone between Capricorn and Rockland. The company’s strategy is to delineate this corridor as a cohesive gold system, potentially linking discrete deposits into a larger resource footprint.

The recent drilling results at Rockland build on earlier high-grade intercepts from the maiden 2025 campaign and the Aquarius prospect, which returned hits including 3m @ 10.2 g/t Au. The structural interpretation suggests shallow to moderately east-dipping mineralised structures controlled by mafic lithologies, consistent across the corridor. This geological continuity underpins Dundas’ confidence in the corridor’s exploration upside.

Focused Portfolio and Exploration Pipeline Rationalisation

Alongside these drilling results, Dundas has exercised its option to acquire the Rockland Mining Lease outright, consolidating ownership as part of its focus on core Kalgoorlie assets. Concurrently, the company has withdrawn its option to acquire several exploration tenements from GTT Metals Group, signalling a strategic pivot to concentrate resources and efforts on advancing the Rockland-Aquarius-Capricorn corridor and the Romano Project further afield.

This disciplined approach follows Dundas’ recent successful $2.5 million capital raise, which was intended to fund drilling programs across its portfolio, including Rockland. The capital injection and lease consolidation set the stage for accelerated exploration activity in this prolific gold district, where Dundas has yet to see systematic mining or extensive drilling despite evident mineralisation potential. The company’s recent initiatives are part of a broader push to unlock value from these underexplored, granted leases with open-ended gold resources.

Next Steps in Drilling and Resource Definition

Dundas plans to follow up the current drilling with deeper and step-out holes to test the down-dip extensions of mineralisation at Rockland and to explore the corridor between Rockland, Aquarius, and Capricorn. The POW lodged for Capricorn will enable drilling aimed at expanding the known resource, which remains open along strike and at depth. The company’s managing director, Jonathan Downes, emphasised the potential for significant upside across the corridor and the intent to continue aggressive drilling campaigns.

Given the early stage of exploration, true widths of mineralisation remain uncertain, and assays are from composite samples pending further detailed analysis. The next tranche of drilling results will be critical to confirming continuity, grade improvements at depth, and the potential to define a coherent resource that could support future development decisions.

These developments come amid Dundas’ broader strategy to advance its Western Australian gold projects, including the Romano Project near major mines, positioning the company to leverage existing infrastructure and regional geological prospectivity. The unfolding story at Rockland and its neighbours will be a key area to watch as drilling progresses and resource models are updated.

Investors and observers will note that Dundas’ recent activities, including the lease acquisition and capital raise, have laid a foundation for what could be a transformative phase of exploration in the Kalgoorlie district, a region with a rich gold mining history but where Dundas is carving out a fresh chapter with its systematic approach.

These assay results and strategic moves provide a tangible signal that Rockland is evolving from discovery to a potentially significant gold system, but the path to resource definition and economic assessment remains contingent on upcoming drilling and geological interpretation.

$2.5M placement completed has underpinned the funding for this drilling phase, while the recent granting of the Mining Lease for Capricorn and plans for immediate drilling there reflect a coordinated effort to unlock value along this mineralised corridor Mining Lease M24/1004 granted. This integrated approach could reveal a larger, connected gold system than previously understood.

Bottom Line?

Dundas’ Rockland results hint at a strengthening gold system at depth, but upcoming drilling will be crucial to confirm resource continuity and corridor linkages.

Questions in the middle?

  • Will follow-up drilling confirm the grade improvements at depth suggested by current intercepts?
  • Can the Rockland-Aquarius-Capricorn corridor be delineated as a single, economically viable gold system?
  • How will the withdrawal from GTT Metals tenements affect Dundas’ exploration pipeline and capital allocation?
