Dundas Minerals (ASX:DUN) expands frontier gold exposure with Romano acquisition

Dundas Minerals has moved to materially expand its gold exploration footprint in Western Australia through the acquisition of an 80% interest in the Romano Project, a district scale landholding in the north eastern Goldfields.

The transaction places the company into a large, under explored terrain on the eastern margin of the Yamarna and Dorothy Hills Shear Zones, a region recognised for hosting large scale gold systems and located adjacent to the operating Gruyere gold mine, while carefully noting that proximity alone is not indicative of mineralisation.

Highlights

• Approximately 800 km² of under explored frontier gold tenure in Western Australia

• Location adjacent to the operating Gruyere gold mine, which contains an estimated ~6 Moz gold resource

• Multiple priority targets identified from historical drilling and geochemical datasets

• Historical intercepts at Bloodwood of 12 m @ 3.3 g/t gold from 20 m within a 5 km gold in soil anomaly

• Historical drilling at Brahman returned 2 m @ 3.9 g/t gold including 1 m @ 7.01 g/t gold

• Earn in structure providing the right to earn 80% ownership through staged exploration expenditure

The Romano Project covers approximately 800 km² of contiguous tenure and sits across the Yamarna and Dorothy Hills Shear Zones, which are recognised structural corridors within the eastern Yilgarn Craton.

Previous exploration undertaken by Gold Road Resources identified multiple gold targets across the project area, providing a technical foundation for further work.

Despite its location in a proven province, the terrain remains sparsely explored relative to established Goldfields districts due to shallow alluvium and sand dune cover, a factor that has historically limited systematic exploration.

Within the Romano tenure, the Bloodwood and Brahman prospects stand out due to historical drilling results.

At Bloodwood, air core drilling defined a coherent gold anomaly extending for approximately 5 km, with limited drilling returning 12 m @ 3.3 g/t gold from 20 m, including a higher grade interval of 4 m @ 9.5 g/t gold.

A subsequent diamond drill hole intersected 2.95 m @ 1.95 g/t gold from 113.45 m, including 0.7 m @ 4.76 g/t gold.

Drilling density across the prospect remains low, particularly given its proximity to the Yamarna Shear Zone and the Golden Highway gold resources located approximately 20 km to the south.

At the Brahman Prospect, historical drilling intersected gold mineralisation within sediments intruded by a dioritic plug, returning a best intercept of 2 m @ 3.9 g/t gold from 92 m, including 1 m @ 7.01 g/t gold.

While the intrusive rocks exhibit broad similarities to others in the region, no direct geological or mineralogical correlation with the Gruyere intrusive has been established, and no Mineral Resources or Ore Reserves have been estimated for the project.

Managing Director Jonathan Downes framed the acquisition within a broader exploration context, noting that “many of Australia’s recent major mineral discoveries, including Gruyere, Hemi and Nova have been made in frontier terrains or on the margins of historically mined districts”, adding that Romano provides exposure to a geological opportunity in a region that remains significantly under explored.

The transaction with Cazaly Resources provides Dundas MineralsRomano acquisition the right to earn 80% of the project through a combination of upfront cash and share consideration, followed by $2,000,000 in exploration expenditure over 2 years.

The structure allows staged commitment while securing access to a large exploration footprint at an early stage of systematic evaluation.

In an environment where new large scale gold discoveries are increasingly rare within mature districts, Dundas’ move into frontier terrain reflects a strategy focused on scale and geological setting rather than near term resource definition.

The Romano acquisition complements the company’s existing Kalgoorlie portfolio and positions it within a proven but under tested province as it builds technical capacity and advances exploration activities into 2026.
