Structural Faults Pose Challenges as Mt Malcolm Mines Advances Golden Crown
Mt Malcolm Mines NL has reported strong gold assay results from its recent drilling at the Golden Crown Prospect, confirming and extending high-grade mineralisation near surface. These findings bolster the project’s potential for near-term, low-impact mining operations.
- Eight-hole RC drilling campaign confirms broad gold mineralisation zones
- Standout intercepts include 3m at 11 g/t Au and 11m at 3.13 g/t Au near surface
- Results extend known mineralisation along the Western Lode at Golden Crown
- Follow-up drilling and resource modelling planned to advance development
- Project positioned for low-capex, small-scale mining with strong metallurgical recoveries
Strong Gold Intercepts Reinforce Golden Crown Potential
Mt Malcolm Mines NL (ASX – M2M) has delivered encouraging assay results from its May 2025 reverse circulation (RC) drilling campaign at the Golden Crown Prospect, part of its 100%-owned Malcolm Project in Western Australia’s Eastern Goldfields. The eight-hole program, totalling approximately 800 metres, successfully intersected gold mineralisation in seven holes, confirming the continuity of near-surface deposits along the Western Lode.
Among the highlights, drillhole 25GCRC008 returned an impressive 11 metres at 3.13 grams per tonne (g/t) gold from just 6 metres depth, including a high-grade 3-metre interval averaging 11 g/t Au, with a standout 1 metre at 30.77 g/t Au. These results not only reaffirm previous drilling but also extend the known mineralised zones, providing a robust foundation for further resource definition.
Strategic Drilling and Geological Insights
The infill drilling was designed with scissor holes to improve structural interpretation, enhancing understanding of the mineralisation geometry. Drillhole 25GCRC007 also delivered broad zones of moderate-grade mineralisation, including 12 metres at 2.15 g/t Au from 16 metres depth. While some holes returned lower grades, they remain geologically significant in outlining the lateral continuity of the mineralised system.
Notably, drillhole 25GCRC002, despite lacking significant gold intercepts, intersected a zone of intense shearing indicative of a fault zone offsetting the eastern and western lodes. This structural information is critical for refining geological models and targeting future drilling.
Advancing Towards Near-Term Production
These drilling results support Mt Malcolm Mines’ strategy to develop Golden Crown as a low-impact, small-scale mining operation. The company has already demonstrated strong gold recoveries from bulk sampling, producing approximately 346 ounces of gold Doré earlier this year. Building on this, Mt Malcolm plans follow-up RC drilling to test extensions of the Western Lode and step-out drilling at the nearby Dumbarton prospect.
Parallel workstreams include updated resource modelling, preliminary pit design, and metallurgical test work aimed at optimising processing pathways. The company is also progressing permitting and environmental approvals to enable near-term production, reflecting a clear pathway from exploration to development.
Regional Context and Exploration Upside
The Malcolm Project spans over 230 square kilometres in a prolific gold region near Leonora, Western Australia, close to established mines such as Genesis Minerals’ Gwalia operation. The Golden Crown Prospect itself has a rich history, having produced 1,720 ounces of gold between 1899 and 1904, and remains open along strike and at depth.
Mt Malcolm Mines intends to continue broader exploration across the project area, targeting multiple untested zones that could further enhance the project’s scale and value. The combination of historical significance, strong recent drilling results, and ongoing exploration positions Golden Crown as a compelling development opportunity.
Bottom Line?
With high-grade gold confirmed near surface and clear development plans underway, Mt Malcolm Mines is poised to unlock Golden Crown’s potential in the near term.
Questions in the middle?
- How will upcoming resource estimates quantify the total gold inventory at Golden Crown?
- What are the projected capital costs and timelines for transitioning to production?
- Could structural complexities identified impact mining methods or resource continuity?
