True North Copper has revealed promising new copper-gold targets at its Wynberg Project in Queensland, building on an existing 56,100-ounce gold resource. The company plans targeted drilling and geophysical surveys to explore extensions and regional prospects.
- Existing Wynberg gold resource of 56.1koz Au on granted mining lease
- Multiple new copper-gold targets identified beyond current resource footprint
- Fixed Loop Electromagnetic (FLEM) surveys highlight deep conductive trends at Burnt Ute
- Exploration plans include drilling extensions and regional target testing
- Wynberg mineralisation shows geological similarities to major Cloncurry district deposits
Wynberg Project: A Strategic Regional Asset
True North Copper Limited (ASX:TNC) has provided a detailed technical update on its 100% owned Wynberg Project, located in the prolific Cloncurry district of northwest Queensland. The project already hosts a JORC 2012-compliant gold resource of 0.64 million tonnes at 2.7 grams per tonne gold, equating to 56,100 ounces, situated on a granted mining lease. However, recent geological reinterpretations and geophysical surveys have uncovered multiple copper-gold targets extending beyond the known resource boundaries, suggesting a much larger mineralised system.
Emerging Copper-Gold Potential Beyond Gold
While Wynberg has historically been explored primarily for shallow gold mineralisation, True North’s latest work highlights significant copper-gold intersections outside the current resource model. Notably, drill intercepts such as 10 metres at 6.7 g/t gold with 0.36% copper and 12 metres at 2.4 g/t gold with 0.75% copper demonstrate the presence of a broader mineralised system. Complementing these findings, Fixed Loop Electromagnetic (FLEM) surveys at the nearby Burnt Ute Prospect have delineated multiple conductive trends extending to depths greater than 600 metres, coincident with strong surface copper-gold geochemistry. These geophysical anomalies are interpreted as potential sulphide-rich bodies, reminiscent of the Jericho copper-gold deposit style.
District-Scale Exploration Corridor
The Wynberg Project is part of a larger regional target portfolio that includes the Burnt Ute, Birdvale, and Black Siltstone prospects. Together, these prospects outline a district-scale copper-gold corridor with geological characteristics comparable to significant Cloncurry deposits such as Wallace North and Jericho. The Burnt Ute Prospect, in particular, exhibits a 1.7-kilometre east-west copper-gold geochemical trend with rock chip samples reaching up to 25% copper and 11.4 g/t gold, underscoring the potential for high-grade mineralisation within trucking distance of True North’s existing infrastructure.
Next Steps: Systematic Exploration and Drilling
True North Copper plans to advance exploration through a combination of field mapping, geochemical sampling, geophysical surveys, and targeted drilling. Priority activities include testing high-priority electromagnetic conductors at Burnt Ute for copper-gold mineralisation and probing down-plunge and strike extensions of the Wynberg gold resource. Additional geophysical surveys at Birdvale and Black Siltstone aim to refine drill targets and support resource growth. The company’s Managing Director Andrew Mooney emphasised the dual focus on unlocking value from gold assets while pursuing copper growth, positioning Wynberg as a key component of True North’s regional discovery pipeline.
Geological Context and Analogues
The Wynberg mineral system is interpreted as an Iron Sulphide Copper-Gold (ISCG) system hosted within the Toole Creek Volcanics, featuring structural complexity, hydrothermal alteration, and brecciation consistent with major Cloncurry district deposits. Analogies to the Wallace North and Jericho deposits provide a compelling exploration model, although True North cautions that these comparisons do not guarantee similar economic outcomes. The project’s granted mining lease and proximity to established processing infrastructure enhance its strategic value.
Bottom Line?
True North Copper’s Wynberg update sets the stage for a potentially transformative exploration campaign that could redefine the company’s copper-gold footprint in Cloncurry.
Questions in the middle?
- Will upcoming drilling confirm extensions to the existing gold resource and uncover significant copper mineralisation?
- How will the geophysical targets at Burnt Ute translate into economically viable deposits?
- What timeline and capital investment will True North allocate to advance these regional targets toward resource definition?
