Dundas Minerals (ASX:DUN) has commenced a reverse circulation drilling programme of approximately six holes for approximately 700 metres at its 100%-owned Rockland Gold Project (M24/974), located approximately 40km north of Kalgoorlie, Western Australia, with drilling focused on following up results from the company's recent eight-hole programme at the project.

Key Points

  • RC drilling has commenced at the 100%-owned Rockland Gold Project, approximately 40km north of Kalgoorlie, Western Australia
  • The programme comprises approximately six RC holes for approximately 700 metres, targeting the southern drill line
  • Drill hole 26RKRC011 previously intersected 12m @ 1.25 g/t Au from 168m, including 4m @ 4.87 g/t Au from 200m (four-metre composites)
  • Seven of eight holes from the recent programme intersected gold mineralisation above the 0.3 g/t Au reporting cut-off
  • Dundas holds the Rockland mining lease subject to a 1.5% net smelter return royalty, with the project on a granted mining lease with an approved Programme of Work

Focus on Southern Drill Line at Rockland

The new drilling programme is focused on the southern drill line at Rockland (6638759mN), where drill hole 26RKRC011 previously intersected two zones of gold mineralisation: 12m @ 1.25 g/t Au from 168m, including 4m @ 2.18 g/t Au from 176m, and 4m @ 4.87 g/t Au from 200m, based on four-metre composite samples with one-metre re-assays pending. Those intercepts extend the interpreted mineralised shoots to approximately 170 metres below surface, where they remain open down dip. The holes in the new programme are designed to follow up the strongest recent results on and around the southern drill line and to improve drill coverage of the mineralised shoots as part of resource definition at Rockland.

Recent Programme Results and Drilling Contractor

The new programme follows an eight-hole RC programme reported on 23 September and 4 November 2026, in which seven of eight holes intersected gold mineralisation. Earlier drilling at Rockland returned 3m @ 6.94 g/t Au from 138m, including 1m @ 20.35 g/t Au from 140m, in hole 26RKRC005. Hole 26RKRC014 returned 12m @ 1.0 g/t Au from 104m, including 4m @ 2.5 g/t Au from 112m, while 26RKRC016 returned no significant result. Drilling is being carried out by Nexgen Drilling Pty Ltd using a track-mounted Schramm T450 RC rig, the same contractor and rig used for the recent programme. All reported intervals are downhole lengths; true widths are not known.

Rockland Gold Project Background

Rockland lies at the southern end of the company's Kalgoorlie Gold Project and is being explored for Archaean orogenic lode gold on the western limb of the Bardoc–Broad Arrow syncline. The company's drilling has outlined a 1km zone of gold mineralisation at Rockland, in stacked shoots interpreted to dip east and remaining open down dip. Rockland, Aquarius, Capricorn and Gemini lie on an interpreted north–south structural corridor extending approximately 3km, although continuity between the prospects has not been established by drilling. Managing Director Jonathan Downes noted that assays are also due from Capricorn and Baden-Powell projects.
