Multiple High-Grade Gold Intercepts Up to 14.9g/t Confirm 1km Rockland Trend

Strong Gold Intercepts Reinforce Rockland Potential

Dundas Minerals Limited (ASX: DUN) has delivered a compelling update from its maiden reverse circulation (RC) drilling program at the Rockland Mining Lease (M24/974), part of the Windanya Gold Project near Kalgoorlie, Western Australia. The company reported multiple high-grade gold intercepts from individual 1 metre samples, confirming a substantial 1 kilometre mineralised trend within the granted lease.

Noteworthy assay results include intercepts such as 6 metres at 3.3 grams per tonne (g/t) gold from 78 metres depth, including a standout 1 metre at 7.5 g/t, and a remarkable 1 metre sample grading 14.9 g/t gold. These results significantly exceed earlier composite sample assays, underscoring the presence of high-grade mineralisation at relatively shallow depths, often less than 100 metres.

New Mineralised Zone Between Historic Prospects

The drilling has delineated a new gold mineralised zone situated between the historic Milford and Windanya North prospects. This zone extends along the entire length of the Rockland Mining Lease and potentially connects northwards to the Aquarius gold deposit. The mineralisation is hosted within deeply weathered mafic lithologies, featuring an oxide supergene zone above stacked structures dipping shallowly eastwards. The north-south orientation of the mineralised trend aligns with the regional geological framework.

Importantly, this is the first systematic drilling campaign at Rockland to test beyond the shallow depths of previous programs, which mostly reached only 50 to 90 metres. Dundas’ deeper drilling to over 150 metres is revealing new geological insights and expanding the known extent of gold mineralisation.

3D Modelling to Guide Next Steps

Dundas is currently undertaking detailed three-dimensional modelling of the latest assay data combined with historical drill information. This modelling aims to clarify the orientation and continuity of mineralisation in fresh rock beneath the oxide zone, providing a robust foundation for planning follow-up drilling campaigns. Managing Director Shane Volk emphasised the significance of these results, noting the widespread nature of mineralisation and the encouraging high-grade intercepts.

Looking ahead, the company is also awaiting assay results from a recently completed 15-hole RC drilling program at the adjacent Baden-Powell Gold Project, expected within two weeks. Together, these exploration efforts position Dundas to refine its exploration model and potentially advance towards resource definition in this prolific gold region.

Strategic Location and Historical Context

The Rockland Mining Lease is strategically located approximately 60 kilometres north of Kalgoorlie and 15 kilometres north of the Paddington gold mill, placing it within a well-established gold mining district. The area has a history of shallow drilling dating back to the 1980s, but Dundas’ recent work represents the first systematic, deeper exploration targeting significant gold mineralisation.

This exploration aligns with Dundas Minerals’ broader strategy to develop its gold assets in the Kalgoorlie region, alongside its battery minerals interests. The company holds options to acquire substantial interests in both the Windanya and Baden-Powell projects, which collectively contain inferred gold resources exceeding 40,000 ounces.
