Copper Strike: QMines Uncovers Significant High-Grade Mineralization at Sulphide City
QMines Limited (ASX:QML) has announced further high-grade copper results from its ongoing drilling program at the Sulphide City deposit, part of the Develin Creek project located 90km northwest of Rockhampton, Queensland. The latest QMines Sulphide City drilling results confirm excellent continuity of copper-zinc-gold mineralization and strengthen the company's multi-project development strategy.
Drilling Success Confirms Resource Potential
The latest drilling campaign has delivered multiple significant copper intersections, with 42 drill holes now completed for 7,890 meters at Sulphide City. Standout results include:
- 16m @ 2.29% CuEq from 135 meters, including 4m @ 4.28% CuEq
- 11m @ 2.39% CuEq from 88 meters, including 7m @ 3.22% CuEq
- 25m @ 1.48% CuEq from 138 meters
- 9m @ 2.38% CuEq from 108 meters
These results continue to validate the company's geological model and confirm Develin Creek's potential as a significant source of material for QMines' planned processing plant at Mount Chalmers.
"The Develin Creek drilling program is progressing well with the Company getting a clearer understanding of the mineralisation and the geometry of the high-grade Sulphide City copper-zinc deposit. The results continue to confirm the Develin Creek project as a significant source of material for the planned Mount Chalmers processing plant." – QMines Executive Chairman Andrew Sparke
Strategic Resource Development
QMines is methodically advancing a three-project development strategy:
| Project | Current Resource | Status |
|---|---|---|
| Mount Chalmers | 11.3Mt @ 0.75% Cu, 0.42g/t Au, 0.23% Zn, 4.6g/t Ag | Ore Reserve established: 9.6Mt @ 0.65% Cu, 0.48g/t Au |
| Develin Creek | 4.2Mt @ 1.01% Cu, 1.16% Zn, 0.15g/t Au, 6.0g/t Ag | Drilling ongoing to expand resource |
| Mount Mackenzie | 3.2Mt @ 1.40g/t Au, 8.4g/t Ag | Maiden drilling to commence October 2025 |
The Develin Creek project now comprises several Volcanic Associated Massive Sulphide (VHMS) copper-zinc deposits, with both Sulphide City and Scorpion-Window deposits showing consistent mineralization in recent drilling.
Understanding VHMS Deposits: Why They Matter to Investors
Volcanic Hosted Massive Sulphide (VHMS) deposits like those at Develin Creek are highly sought after by mining companies due to their typically high grades and polymetallic nature. These deposits form through submarine volcanic processes, where metal-rich fluids concentrate in favorable geological settings.
VHMS deposits are particularly valuable because:
- They often contain multiple valuable metals (copper, zinc, gold, silver)
- They can form well-defined, predictable ore bodies
- They frequently occur in clusters, creating district-scale mining opportunities
For investors, VHMS deposits represent potential for high-margin operations due to the presence of multiple revenue streams from different metals, as demonstrated by QMines' copper equivalent calculations incorporating copper, zinc, gold, and silver values.
Development Timeline and Catalysts
QMines has outlined several near-term catalysts that could drive share price appreciation:
- Continued Drilling Results: Ongoing diamond drilling with recent QMines Sulphide City drilling results to be released as received
- Resource Updates: Updated mineral resource estimates following completion of drilling
- Mount Mackenzie Drilling: Maiden drilling program to commence in October 2025
- Mine Design Advancement: Open pit design work underway for Scorpion-Window pit
- Metallurgical Test Work: PFS-level testing across all three projects
- Updated Pre-Feasibility Study: Comprehensive PFS scheduled for H2-2026
The company is focused on creating a hub-and-spoke development model with Mount Chalmers as the processing center, fed by multiple satellite deposits across its project portfolio.
Investment Case: A Multi-Project Copper Developer
QMines presents a compelling investment case based on several key strengths:
- Resource Growth Potential: Multiple deposits still open in multiple directions
- Polymetallic Revenue Streams: Copper, zinc, gold, and silver provide commodity diversification
- Strategic Location: All projects located in mining-friendly Queensland, near infrastructure
- Staged Development Approach: Mount Chalmers Ore Reserve establishes foundation for growth
- Experienced Management: Team with strong track record in resource development
With 7,890 meters of drilling completed at Sulphide City and further diamond drilling underway, QMines is rapidly advancing its understanding of the deposit's geometry and grade distribution. The combination of broad mineralized zones and high-grade intercepts provides flexibility for future mining scenarios.
Why Investors Should Follow QMines
QMines represents a rare opportunity in the ASX-listed copper space – a company with established resources, ongoing exploration success, and a clear pathway to production. Furthermore, the latest QMines Sulphide City drilling results continue to validate the company's geological model and strengthen the economics of its multi-deposit development strategy.
With copper prices projected to remain strong due to global electrification trends, QMines is well-positioned to capitalise on increasing demand for this critical metal. The company's diversified portfolio of copper, zinc, gold, and silver assets provides natural hedging against commodity price fluctuations while maintaining focus on copper as the primary value driver.
As QMines continues to advance toward its updated Pre-Feasibility Study in 2026, investors have multiple near-term catalysts that could drive significant value appreciation, starting with continued drilling results from Sulphide City and the upcoming maiden drilling program at Mount Mackenzie.
