Cockie Creek Resource Estimate Nears as Steam Engine Advances Toward Production
Superior Resources Limited has expanded its copper exploration strategy to include high-grade copper-gold targets alongside porphyry prospects, while progressing the Steam Engine Gold Project towards early production within two years.
- Expanded copper strategy to target high-grade copper-gold alongside porphyry systems
- Cockie Creek porphyry prospect maiden JORC resource estimate imminent
- Steam Engine Gold Project advancing feasibility, regulatory approvals, and resource updates
- New geophysical data reveals potential extensions and new lodes at Steam Engine
- Termination of Queensland CEI grant program due to weather delays; plans to reapply
Expanding Copper Horizons in Queensland
Superior Resources Limited, an ASX-listed mineral explorer based in Brisbane, has broadened its copper exploration focus within its extensive Greenvale Project in northeast Queensland. Traditionally centred on porphyry copper-gold-molybdenum systems, the company is now actively delineating high-grade copper-gold-silver opportunities, including historically mined prospects such as the Hall’s Reward Copper Mine and the Wyandotte Prospect. These targets, some with historical production boasting exceptional grades, offer promising avenues for near-term resource growth alongside the company’s established porphyry programs.
Cockie Creek Porphyry Resource on the Horizon
Following a successful drilling campaign in 2023, Superior is nearing completion of a maiden JORC (2012) Mineral Resource Estimate for the Cockie Creek porphyry copper-gold-molybdenum prospect. The drilling returned better-than-expected grades and thicknesses, reinforcing the prospect’s potential as a significant contributor to the company’s copper portfolio. The resource estimate is anticipated to be released during the third quarter of 2025, marking a key milestone in the project’s development.
Steam Engine Gold Project – On Track for Early Production
The Steam Engine Gold Project, situated within the Greenvale portfolio, is advancing steadily towards early gold production, targeted within two years. The company has progressed its feasibility study, focusing on a toll treatment operation, and is concurrently updating its Mineral Resource Estimate incorporating recent drilling results. Regulatory pathways are being actively navigated, including native title and cultural heritage engagements, alongside mining lease applications. Notably, advanced 3D modelling of sub-audio magnetics (SAM) geophysical data has identified highly anomalous features suggestive of previously unknown gold lodes, including potential extensions of the main Steam Engine Lode at shallow depths.
Geophysical Insights and Exploration Momentum
The SAM survey data has been instrumental in highlighting new exploration targets at Steam Engine, with anomalies mirroring the geophysical signatures of known high-grade zones. These findings have prompted planning for priority drilling programs to test these targets, pending cultural heritage clearances. Similarly, at the Greenvale Project, reconnaissance programs are underway at high-grade copper-gold prospects such as Hall’s Reward and Telegraph, aiming to expand the resource base and validate new mineralised zones.
Navigating Challenges and Strategic Funding
Despite progress, Superior Resources faced setbacks with the termination of a Queensland Government Collaborative Exploration Initiative (CEI) grant due to prolonged monsoon conditions limiting drilling execution. However, the company views this as an opportunity to refine its drilling targets using new 3D gravity models and plans to reapply for future CEI funding. Financially, the company reported cash outflows from operating and investing activities for the quarter, ending with a cash balance of AUD 684,000. Payments to directors and related parties were disclosed, reflecting ongoing corporate governance transparency.
Bottom Line?
Superior Resources is positioning itself at the forefront of copper and gold exploration in Queensland, with upcoming resource updates and drilling results set to shape its near-term production and growth trajectory.
Questions in the middle?
- How will the imminent Cockie Creek resource estimate influence Superior’s development plans and investor sentiment?
- What impact will the newly identified SAM geophysical anomalies have on the overall resource potential at Steam Engine?
- How will the company manage funding and operational risks following the termination of the CEI grant program?
