White Cliff Minerals has delivered a standout 50.9m intercept at 2.81% copper in its first diamond drill hole at Danvers 1, validating its geological model and setting the stage for targeted step-out drilling to expand the Rae Copper Project’s footprint.
- First diamond hole returns 50.9m at 2.81% Cu including 4.3m at 10.93% Cu
- Mineralisation begins shallow at 39.7m depth, confirming near-surface potential
- Assays validate continuity and high-grade zones within chlorite-altered breccia
- Diamond core provides structural data to guide future drilling
- Additional diamond assays pending to refine scale and grade
Exceptional First Diamond Drill Results at Danvers 1
White Cliff Minerals (ASX:WCN) has hit a significant milestone at its Rae Copper Project with the first diamond drill hole at Danvers 1 delivering a broad, high-grade copper intercept. Hole DAN26026 returned 50.9 metres grading 2.81% copper and 7.66 g/t silver starting from just 39.7 metres downhole, including a standout 4.3 metres at 10.93% copper and 15.6 g/t silver. This near-surface mineralisation confirms the shallow nature of the deposit and bolsters confidence in the project’s scale potential.
The high-grade intervals are dominated by bornite and chalcocite, key copper sulphides that underpin the mineralisation’s quality. The results not only confirm previous reverse circulation (RC) drilling but also validate White Cliff’s geological model, showing continuity within the chlorite-altered breccia that hosts the copper mineralisation.
Structural Insights from Oriented Diamond Core
Beyond grades, the diamond core has provided critical structural data. This is the first orientated core from Danvers 1, allowing geologists to build a structural framework that sharpens targeting for follow-up drilling. Understanding the controls on mineral distribution is vital for expanding the footprint and identifying thicker, higher-grade zones along the Teshierpi Fault Zone.
Managing Director Troy Whittaker highlighted the result as a “further demonstration of the exceptional tenor and scale potential” of Danvers, noting the Phase 1 drilling program is nearing completion. With pending assays from additional diamond holes, the company is poised to systematically step out from these high-grade zones to define the ultimate size of the system.
Context within Rae Copper Project and Historical Data
Danvers is part of the Rae Copper Project in Nunavut, Canada, a region with a rich exploration history but still emerging as a copper district. The historic resource estimate at Danvers, dating back to the 1960s, cited 4.16 million tons at 2.96% copper but is not JORC-compliant and requires modern validation. White Cliff’s drilling is providing the contemporary data needed to underpin a new resource estimate.
The Rae Project also includes the Hulk sediment-hosted copper deposit, where recent drilling has expanded the mineralised footprint to over 6 square kilometres. White Cliff is integrating these discoveries with geophysical surveys and metallurgical test work that show promising copper and silver recoveries above 90%, indicating potential for economic extraction.
Next Steps and Exploration Outlook
White Cliff is continuing diamond drilling with multiple assays pending, including from step-out holes testing previously identified high-grade zones. The company’s technical team is focused on refining the geological and structural model to improve drill targeting and confirm mineralisation continuity. This methodical approach aims to transition from exploration to resource definition.
Given the broad intercepts and high grades intersected early in the diamond program, the Rae Copper Project is shaping up as a significant copper discovery in a globally strategic jurisdiction. The market will be watching closely as further assay results and drilling updates emerge, potentially reshaping the project’s valuation and development trajectory.
Bottom Line?
White Cliff’s first diamond hole at Danvers delivers compelling evidence of a continuous, high-grade copper system, setting a clear path for targeted drilling to unlock the Rae Project’s full potential.
Questions in the middle?
- How will pending diamond assays refine the understanding of Danvers’ mineralisation continuity?
- What scale of expansion can step-out drilling achieve beyond the current mineralised footprint?
- How will metallurgical test results influence the economic viability and processing strategy?
