White Cliff Minerals Uncovers 75m of High-Grade Copper at Rae Project
White Cliff Minerals reports compelling new assay results from its Rae Copper Project in Nunavut, revealing extensive high-grade copper and silver mineralisation along a 5km strike. The findings set the stage for expanded drilling and geophysical surveys to unlock the project's full potential.
- 75m intercept at 2% copper and 6.8g/t silver from shallow depths
- High-grade zone of 18.3m at 4.66% copper and 17.2g/t silver within drillhole DAN25006
- Surface samples confirm mineralisation extends over ±5km strike length
- Step-out drilling planned to test untested extensions of Danvers breccia system
- Drone-mounted MobileMT geophysical survey to refine exploration targets
Significant Assay Results from Rae Copper Project
White Cliff Minerals Limited (ASX: WCN) has announced further encouraging assay results from its ongoing reverse circulation drilling campaign at the Rae Copper Project in Nunavut, Canada. The standout intercept from drillhole DAN25006 returned 75 metres grading 2% copper and 6.8 grams per tonne silver starting from just 7 metres downhole. Within this broad zone, a high-grade section of 18.3 metres at 4.66% copper and 17.2 grams per tonne silver was identified, underscoring the robust mineralisation potential at Danvers.
Additionally, the drilling revealed a previously unrecognised sub-parallel mineralised structure, with 12.19 metres at 1.13% copper and 2.13 grams per tonne silver intercepted further downhole. This discovery hints at a more complex and potentially richer mineral system than previously understood.
Extensive Surface Mineralisation Confirmed
Complementing the drilling results, surface rock chip sampling along the same structural trend southwest of Danvers has returned impressive copper and silver grades over a 5-kilometre strike length. Samples yielded copper grades as high as 16.15% and silver up to 74 grams per tonne, confirming that high-grade mineralisation is not confined to the drill area but extends significantly along the regional fault zone.
This structural corridor, visible in aerial imagery, remains largely undrilled, presenting a substantial exploration upside. White Cliff Minerals plans to undertake step-out drilling to test the continuity of the Danvers breccia-style mineralisation along this trend, which has never before been systematically explored.
Advanced Geophysical Survey to Accelerate Exploration
To better understand the subsurface geology and guide future drilling, the company will deploy a high-resolution drone-mounted MobileMT geophysical survey over the Rae licence area. This survey aims to fingerprint the geophysical signature of the Danvers mineralisation, enabling rapid and accurate identification of repetitions or extensions of the breccia and vein-fill style copper-silver deposits.
These geophysical insights, combined with ongoing drilling, will be critical in refining exploration targets and advancing the project towards a maiden JORC-compliant mineral resource estimate.
Historic Context and Future Outlook
The Rae Copper Project hosts a historic resource estimate of approximately 4.16 million tonnes at 2.96% copper, though this estimate is not JORC-compliant and requires modern verification. The recent results, alongside digitised historic data and new surface sampling, suggest that the Danvers structural zone could be significantly larger and more mineralised than previously thought.
White Cliff Minerals is preparing to mobilise its drilling and geophysical teams to site imminently, with plans to also initiate maiden drill programs at other promising targets within the Rae Project, including Hulk, Rocket, Thor, Vision, and Stark. Managing Director Troy Whittaker expressed optimism about the extraordinary potential of the area, highlighting the continuity of high-grade mineralisation over a substantial strike length.
Bottom Line?
White Cliff Minerals’ latest results at Rae open a new chapter of exploration with high-grade copper-silver mineralisation extending over kilometres, setting the stage for a potentially transformative resource update.
Questions in the middle?
- Will upcoming step-out drilling confirm the continuity and true thickness of the Danvers mineralised structures?
- How will the MobileMT geophysical survey refine target selection and impact drilling success rates?
- What are the financial implications and timing of the net smelter royalty buyback option held by White Cliff Minerals?
