Qmines Ltd
QMines Limited (ASX:QML) has made a significant exploration breakthrough at its Mount Mackenzie gold and silver project in Central Queensland, with visible gold observed in diamond core from hole MMDD010 at the newly identified Vein 355 prospect. This visible gold discovery by QMines Ltd occurs within a vuggy, strongly oxidised volcanic breccia containing silica veinlets and oxidised sulphide relics—precisely the geological setting expected in a high-grade epithermal system.
The visible gold observation at 11-12 metres depth marks a new qualitative discovery from QMines' first purpose-designed diamond drilling programme at this target, with coarse gold grains (~0.5mm) observed as localised clusters within a highly permeable breccia horizon. Furthermore, the adjacent 12-21 metre interval displays the same breccia style and geological characteristics, with all samples now at the laboratory on rush priority for assay results.
Breaking Discovery Reinforces Mount Mackenzie's High-Grade Potential
With nine holes now complete at Vein 355 and eight additional holes planned, QMines is rapidly advancing this high-priority target within a proven high-sulphidation epithermal system that already hosts 3.4Mt at 1.40g/t gold and 8.4g/t silver in indicated and inferred resources.
The visible gold discovery by QMines Ltd validates QMines' geological model for Mount Mackenzie as a high-sulphidation epithermal system with exceptional exploration potential. In addition, the host geology demonstrates all the hallmarks of a productive epithermal environment.
Key Geological Indicators:
- Vuggy silica and residual quartz in the core alteration zone
- Pyrite-enargite-covellite-tennantite sulphide assemblage indicating high-temperature mineralisation
- Multiple pulses of brecciation and fluid flow suggesting a long-lived system
- Classic alteration zonation from silica-pyrite-alunite to outer advanced argillic assemblages

Understanding Epithermal Systems: Why This Discovery Matters for Investors
Epithermal systems are shallow, hot-spring style deposits formed by mineral-rich fluids circulating near active volcanoes. These systems often produce some of the world's highest-grade gold deposits because they concentrate precious metals in narrow, high-grade zones through intense fluid circulation and chemical precipitation processes.
The "vuggy" texture observed at Vein 355—essentially cavities left behind when minerals dissolved—indicates intense fluid flow through permeable rock. Consequently, this geological setting creates ideal trapping sites for gold precipitation and typically correlates with higher gold grades compared to other deposit types.
The presence of enargite (a copper-arsenic sulphide) proves particularly significant, as it typically forms at temperatures of 200-300°C and often signals proximity to even higher-grade mineralisation. For investors, this geological evidence suggests Mount Mackenzie could host multiple high-grade targets beyond the current discovery, potentially expanding the project's resource base and economic potential.
Drilling Programme Delivers Strategic Intelligence
QMines' systematic approach to exploring Mount Mackenzie is already producing results, with the diamond drilling programme providing crucial geological intelligence that historical percussion drilling couldn't deliver. However, the visible gold discovery by QMines Ltd represents just the beginning of a comprehensive exploration strategy.
| Programme Highlights | Details |
|---|---|
| Drilling Method | Diamond core (HQ3 triple tube) |
| Holes Completed | 9 holes at Vein 355 |
| Additional Holes Planned | 8 holes for strike continuity |
| Assay Status | All samples on rush priority |
| Discovery Hole | MMDD010: Visible gold 11-12m depth |
The diamond drilling has revealed continuous breccia textures and high-resolution geological detail impossible to achieve with historical methods. Furthermore, the 12-21 metre interval below the visible gold shows the same geological characteristics, suggesting potential continuity of the mineralised system.
Exploration Manager Commentary
"Visible gold in intact core from hole MMDD010 confirms that mineralising fluids accessed a highly permeable breccia horizon at Vein 355. The observation is hosted by vuggy, strongly oxidised volcanic breccia with remnant silica veinlets and oxidised sulphides, consistent with an epithermal vein breccia setting within the Mount Mackenzie system." – Tom Bartschi, Exploration Manager
Strategic Context: Building on Proven Resource Base
The Mount Mackenzie discovery advances QMines' position as the company continues developing its flagship Mount Chalmers copper-gold project, which hosts 9.6Mt of proved and probable ore reserves and represents a clear pathway to production. In addition, the company's total resource base across its Queensland projects now stands at 15.5Mt, positioning QMines as a significant emerging player in the region.
QMines' Project Portfolio:
| Project | Status | Resource/Reserve | Key Metals |
|---|---|---|---|
| Mount Chalmers | Development | 9.6Mt Ore Reserves | Cu, Au, Zn, Ag |
| Develin Creek | Resource | 4.1Mt Resource | Cu, Zn, Au, Ag |
| Mount Mackenzie | Exploration/Resource | 3.4Mt Resource | Au, Ag |
The visible gold discovery by QMines Ltd at Mount Mackenzie provides QMines with a high-grade gold exploration play to complement its copper-focused development projects. Consequently, this creates multiple value drivers for the company across different commodity exposures.
Next Steps: Rapid Resource Definition Strategy
QMines has outlined an aggressive timeline to convert the visible gold discovery into defined mineralisation through systematic exploration and technical assessment.
Immediate Priorities:
- Rush assay results from MMDD010 priority intervals
- Complete eight additional step-out holes to test strike continuity
- Detailed geological logging to define breccia controls and permeability traps
- Extinction assay testing to quantify coarse gold components
Medium-Term Objectives:
- Determine whether Vein 355 represents a discrete high-grade zone or broader structural corridor
- Optimise drilling orientations to intersect dominant structural controls
- Assess supergene enrichment potential in the oxidised profile
The company's systematic approach focuses on rapidly determining geometry and continuity whilst maintaining cost-effective exploration spending across its project portfolio.
Investment Considerations: Multiple Catalysts Converging
QMines presents an investment opportunity with multiple value catalysts now aligning across its project portfolio, creating potential re-rating opportunities as each project advances.
Near-Term Catalysts:
- Rush assay results from Mount Mackenzie visible gold discovery
- Mount Chalmers development progression toward production decision
- Continued resource expansion across Queensland projects
Medium-Term Value Drivers:
- High-grade gold discovery potential at Mount Mackenzie epithermal system
- Copper production pathway through Mount Chalmers development
- Regional consolidation opportunities in established Queensland mining district
Strategic Positioning:
- 100% project ownership across all key assets
- Proven management team with technical and development experience

- Diversified commodity exposure to copper, gold, silver, and zinc
Financial and Corporate Structure
QMines maintains a reasonable capital structure for a company with multiple development and exploration assets, with 647.6 million shares on issue and 38 million unlisted options. This structure provides the company with flexibility to advance its projects whilst managing dilution considerations.
However, the company's cash position and funding requirements for advancing Mount Mackenzie exploration alongside Mount Chalmers development will be important factors for investors to monitor as both projects progress through their respective development pathways.
