Dundas Minerals Locks in Continuous Kalgoorlie Gold Belt With Drilling Due September
Key Takeaways
- Dundas Minerals has consolidated nine prospecting licences into a single, continuous land position along the Bardoc gold trend, 40–50km north of Kalgoorlie, spanning an interpreted 3km north–south structural corridor from Rockland through to Gemini.
- The Gemini prospect carries a standout historical intercept of 2m @ 26.68 g/t Au from 35m — including 1m @ 39.71 g/t Au — yet the entire RC programme covered only a 45m by 45m cluster, leaving the strike extent and depth entirely untested.
- The Gemini acquisition cost just $70,000 in cash from existing reserves, with the six Windanya licences transferred at no new cash outlay under a pre-existing option agreement.
- A drilling contractor is already engaged and the campaign is scheduled to commence late September 2026, targeting Rockland, Capricorn, Aquarius, Baden-Powell, and Gemini across a fully permitted, heritage-cleared programme.
- The Bardoc Tectonic Zone has historically produced in excess of 100 tonnes of gold, and Dundas now holds contiguous tenure across multiple high-grade prospects within that system.
Dundas Minerals consolidates Kalgoorlie gold belt with high-grade Gemini acquisition
Dundas Minerals (ASX: DUN) has stitched together a single, continuous land position along the Bardoc gold trend, 40–50km north of Kalgoorlie, Western Australia, through the acquisition of nine prospecting licences. The standout historical result from the newly acquired Gemini prospect — 2m @ 26.68 g/t Au from 35m, including 1m @ 39.71 g/t Au — underscores why the company is moving quickly, with a drilling contractor already engaged and drilling scheduled to commence in late September 2026.
Jonathan Downes, Managing Director
“This acquisition is a major step forward for Dundas. These nine licences stitch our holdings into a single, continuous position along a prolifically mineralised Eastern Goldfields’ structure, running from Rockland through Capricorn and Aquarius to Gemini in the north… With the Capricorn Mining Lease granted, Programmes of Work approved and a drilling contractor engaged, we now hold the targets, the tenure and the opportunity.”

Nine licences, one connected gold corridor
The consolidation was completed under two separate transactions, each with distinct consideration.
Gemini Project (P24/5796, P24/5797, P24/5798):
- Three granted prospecting licences, all granted 31 August 2025
- Acquired outright from a private vendor for total cash consideration of $70,000, funded from existing cash reserves
- Includes the Gemini prospect (high-grade gold) and the Blue Reef prospect (historical mine workings)
- Native title addressed via an executed State Government Regional Standard Heritage Agreement
Windanya licences (P24/5800 to P24/5805):
- Six prospecting licences, granted 3 July 2026; transfers registered by the Department of Mines, Petroleum and Exploration on 19 August 2026
- Transferred under the original Black Mountain Option Agreement (announced 30 August 2023); consideration for this package was settled under that pre-existing agreement — no new cash outlay was required
- Licences lie within the Broad Arrow Mineral Field over the Mt Vetters pastoral lease
All nine licences are granted and tenure is in good standing.
What the belt looks like now
The combined position spans an interpreted north–south structural corridor of approximately 3km, running from Rockland in the south through Aquarius and Capricorn to Gemini in the north. This is a single interpreted mineralised system along the Bardoc gold trend. Continuity of mineralisation between the individual prospects has not yet been established by drilling, and testing that continuity is a priority target for the forthcoming drill campaign.
High-grade gold at Gemini: what the historical drilling shows
Historical drilling at the Gemini prospect was completed by Maritana Minerals Ltd (ASX: MRT, formerly Horizon Minerals Ltd) between 2020 and 2022, comprising 11 aircore holes for 623m and 7 RC holes for 673m. Dundas has reconciled all reported intercepts against the primary digital assay data lodged with DEMIRS (WAMEX A145108). The key results are set out below.
All intervals are downhole lengths; true widths are not known.
| Hole ID | Type | From (m) | Interval (m) | Grade (Au g/t) |
|---|---|---|---|---|
| WAC20019 | AC | 35 | 2 | 26.68 (incl. 1m @ 39.71 g/t Au) |
| GMRC21001 | RC | 38 | 2 | 8.66 |
| GMRC21001 | RC | 53 | 3 | 4.19 |
| GMRC21001 | RC | 41 | 2 | 2.16 |
| GMRC21005 | RC | 59 | 1 | 2.01 |
Why Gemini remains underexplored
The historical RC drilling programme tested only a small fraction of the Gemini prospect’s potential. The seven RC holes were confined to a tight cluster spanning approximately 45m by 45m, centred on the position of aircore hole WAC20019. In practical terms, that means the programme confirmed high-grade gold in one small area but left the vast majority of the structure untouched.
Key gaps the data reveals:
- Historical aircore drilling did not penetrate beyond the shallow, oxidised horizon — bedrock beneath remains effectively untested
- The RC cluster covered only ~45m by 45m; the strike extent of the mineralised system is untested
- Mineralisation is interpreted to remain open at depth and along strike to both north and south, including down the interpreted southerly plunge
What the Kalgoorlie gold belt means for investors
A “gold belt” is a linear zone in the Earth’s crust where structural features — faults, shear zones, and geological contacts — have channelled hydrothermal fluids over millions of years, precipitating gold along predictable corridors. The Bardoc Tectonic Zone, which hosts Dundas’ project area, sits within the Eastern Goldfields Province of the Archaean Yilgarn Craton in Western Australia, one of the world’s most productive gold-bearing geological terranes. The Bardoc Tectonic Zone has produced in excess of 100 tonnes of gold historically from a range of deposits.
The style of mineralisation being targeted is orogenic (lode) gold, where gold is deposited in quartz veins and stockworks along structural corridors. For exploration investors, consolidating a continuous land position along such a corridor matters because it removes the risk of a discovery running onto a competitor’s ground — and it gives a single operator the ability to test the full system. Dundas now holds contiguous tenure across a belt with high-grade historical results at multiple prospects and key sections that remain entirely undrilled.

Drilling imminent: what comes next for DUN
Dundas is moving into its most active exploration period to date. Programmes of Work (POW) have been approved across multiple targets, and a drilling contractor has been engaged for a campaign scheduled to commence late September 2026. The planned sequence is:
- Rockland — follow-up drilling on previously reported high-grade discovery intercepts; POW approved, contractor engaged. Recent results include 3m @ 6.9 g/t Au from 138m (26RKRC005), 2m @ 3.3 g/t Au from 59m (26RKRC010), and 6m @ 1.0 g/t Au from 69m (26RKRC003).
- Capricorn — extensional and infill drilling on the newly granted Mining Lease, which hosts a previously reported Mineral Resource Estimate; POW approved. The required Aboriginal heritage survey was completed 4 July 2026 and returned the entire survey area clear. Internal conceptual pit shell optimisations have been used as a drill-targeting tool to identify areas where additional drilling may improve geological confidence — this work is preliminary, is not a mining study, and does not establish economic viability.
- Between Rockland and Capricorn — programme planned to test interpreted corridor continuity, including the Aquarius prospect, which returned 3m @ 10.2 g/t Au from 109m (23WDRC012) in earlier drilling and remains effectively untested below shallow depths.
- Baden-Powell — POW approved for drilling at the open-ended northern deposit.
- Gemini — follow-up drilling planned to target the interpreted southerly plunge and to test strike extent beyond the existing 45m by 45m RC cluster; timing is subject to near-term commitments at Rockland, Capricorn, and Baden-Powell.
The high-grade gold shoots at Rockland have already shaped how Dundas is sequencing its broader campaign, with the 2km structural corridor interpretation informing where infill and extensional holes are being prioritised across the belt.
The results from Rockland have already supported Dundas’ interpretation of mineralised shoots within a prospective north–south structural corridor. With tenure secured, Programmes of Work approved, heritage clearances in hand, and a contractor engaged, the company holds what Managing Director Jonathan Downes described as “the targets, the tenure and the opportunity” heading into the upcoming drill season.
