Mt Malcolm Mines NL has reported promising gold assay results from its 2025 drilling programs at the Sunday Underground and Dumbarton prospects, confirming continuous shallow mineralisation and advancing the Malcolm Project towards resource estimation.
- Shallow gold mineralisation confirmed over 700m strike length at Dumbarton
- High-grade gold intercepts including 8m @ 1.20 g/t Au from surface at Sunday Underground
- Follow-up drilling planned to test extensions and infill gaps at South Picnic
- Results support potential for near-term resource growth and open-pit mining
- Progression towards maiden JORC Mineral Resource Estimate underway
Encouraging Drilling Results at Malcolm Project
Mt Malcolm Mines NL (ASX – M2M) has released highly encouraging assay results from its 2025 reverse circulation (RC) drilling campaigns at the Sunday Underground, South Picnic, and Dumbarton prospects within the Malcolm Project in Western Australia. These results confirm the presence of shallow, continuous gold mineralisation over significant strike lengths, reinforcing the project's potential for near-term resource growth and development.
The Dumbarton drilling program, comprising 18 holes totaling 1,825 metres, demonstrated continuity of gold mineralisation over a 700-metre strike length. Notable intercepts include 3 metres at 2.19 grams per tonne (g/t) gold from 58 metres, with a high-grade 1-metre interval at 4.48 g/t Au. These findings build on previous drilling and historic workings, highlighting multiple mineralised lode systems that remain open along strike and at depth.
Shallow Mineralisation Confirmed at Sunday Underground
At the Sunday Underground Prospect, an inaugural 540-metre, 8-hole RC program confirmed shallow gold mineralisation beneath historic workings. Key intercepts include 8 metres at 1.20 g/t Au from surface, featuring a higher-grade 1-metre interval at 4.05 g/t Au. Additional results from the South Picnic infill drilling south of the Picnic workings are pending, expected to further clarify mineralisation continuity and support resource estimation efforts.
Managing Director Trevor Dixon expressed optimism about the results, noting the minimal drilling metres required to confirm significant shallow mineralisation and the continuity demonstrated at Dumbarton. He emphasized that these results advance the establishment of a robust resource base and underpin the company’s commitment to unlocking the full potential of the Malcolm Project.
Geological Context and Exploration Strategy
The Malcolm Project is situated within the Norseman–Wiluna Greenstone Belt, part of the Eastern Goldfields Superterrane, a prolific gold-producing region. Mineralisation is structurally controlled, associated with quartz-carbonate-pyrite veining in sheared mafic and felsic volcanics, and occurs within shallow oxide and saprolite zones amenable to low-cost open-pit mining.
The drilling programs have been designed to test strike and down-plunge extensions of mineralised lodes, validate historical high-grade intercepts, and infill gaps to improve geological confidence. The continuity of mineralisation between historic workings and recent drilling supports the development of a maiden JORC (2012) Mineral Resource Estimate, a critical milestone for advancing the project towards production.
Next Steps and Development Potential
Mt Malcolm Mines plans to incorporate the 2025 drilling data into updated 3D geological and structural models. Follow-up drilling is planned to test open strike and depth extensions, particularly at Dumbarton where mineralisation remains open. The company is also assessing low-capital expenditure mining options, aiming to leverage the shallow, open-pittable nature of the mineralisation.
Pending assay results from the South Picnic infill program will be pivotal in refining exploration and development strategies. Together with ongoing geological modelling and resource estimation, these efforts position the Malcolm Project as a promising near-term development opportunity within Western Australia’s Eastern Goldfields.
Bottom Line?
With strong shallow gold intercepts and continuity confirmed, Mt Malcolm Mines is poised to advance the Malcolm Project towards a maiden resource estimate and potential mining development.
Questions in the middle?
- What will the pending South Picnic infill drilling results reveal about mineralisation continuity?
- How will Mt Malcolm Mines prioritize follow-up drilling to test depth and strike extensions?
- What are the potential capital requirements and timelines for advancing towards production?
