Danvers Drilling Yields 49m at 1.33% Copper, Expands Rae Project Potential

White Cliff Minerals has unveiled assay results from its 2025 drilling campaign at the Danvers prospect, significantly extending the known high-grade copper mineralisation and revealing new geophysical targets that promise further discoveries.

  • 2025 drilling more than doubles known strike length at Danvers
  • Notable intercepts include 49m @ 1.33% Cu and 33.53m @ 1.02% Cu
  • Drone-based Mobile MT and heliTEM surveys identify large conductive anomalies
  • Historic resource estimate remains non-JORC compliant, pending verification
  • Ongoing assay releases and integrated geophysical targeting planned

Expanding the Danvers Copper Footprint

White Cliff Minerals Limited (ASX – WCN) has reported compelling early assay results from its 2025 reverse circulation drilling program at the Danvers prospect, part of the Rae Copper Project in Nunavut, Canada. The initial batch of assays reveals extensive zones of copper mineralisation that more than double the previously known strike length, underscoring the prospect’s growing significance.

Key drillholes include DAN25013, which intersected 49 metres grading 1.33% copper, including a high-grade 3-metre section at 6.6% copper and 23.95 grams per tonne silver, and DAN25010, which returned 33.53 metres at 1.02% copper with a standout 12.2-metre interval at 2% copper. These results confirm the presence of substantial mineralised envelopes beyond the historic resource boundaries.

New Geophysical Insights Drive Exploration

Complementing the drilling, White Cliff has deployed advanced geophysical techniques, including a drone-based Mobile Magneto-Tellurics (MT) survey and a helicopter-borne electromagnetic (heliTEM) survey. These surveys have delineated large conductive anomalies and multiple parallel structures within the Teshierpi Fault Zone, many of which remain untested by drilling.

The integration of these geophysical datasets with drilling results has led to a reinterpretation of the Danvers mineralisation system. The current drill intercepts appear to lie on the periphery of a massive conductive anomaly offset by strike-slip faulting, suggesting the main high-grade core remains undrilled approximately 200 metres to the northwest. This insight sets the stage for targeted follow-up drilling campaigns aimed at unlocking the deposit’s full potential.

Historic Resource and Forward Strategy

While the historic resource estimate at Danvers, dating from the 1960s, indicated approximately 4.16 million tons at 2.96% copper, it is not compliant with modern JORC standards. White Cliff acknowledges this and plans verification drilling and updated resource modelling to bring the estimate in line with current reporting codes.

The company is managing assay delays caused by high exploration activity in the region but anticipates a steady stream of assay results over the coming months. These will be integrated with ongoing geophysical data to refine drill targeting across the 10-kilometre Danvers strike and adjacent Rae sedimentary targets.

Broader Project Context

The Rae Copper Project is situated in a highly prospective geological setting known for sediment-hosted copper deposits, with similarities to major global copper belts. White Cliff’s exploration success at Danvers builds on previous high-grade discoveries in the region, including the Phoenix prospect and Slider, reinforcing the project’s strategic importance in the company’s portfolio.

Managing Director Troy Whittaker highlighted the significance of the new data, emphasizing the potential for further high-grade discoveries guided by the enhanced geophysical resolution now available. The company’s multi-pronged exploration approach combining drilling, geophysics, and historic data digitisation positions it well to advance the Rae Copper Project towards resource definition and eventual development.

Bottom Line?

White Cliff’s expanding footprint at Danvers, powered by integrated drilling and geophysics, sets the stage for a transformative phase in Nunavut copper exploration.

Questions in the middle?

  • How will upcoming assay results reshape the understanding of the Danvers mineral system?
  • What is the timeline and scope for verifying and upgrading the historic resource to JORC standards?
  • How might the newly identified conductive anomalies influence future drilling priorities and resource growth?
