New Geophysical Insights at Danvers

White Cliff Minerals Limited (ASX – WCN) has announced the receipt of phase one airborne geophysical data from its Danvers region within the Rae Copper Project in Nunavut, Canada. The data, derived from a helicopter-borne electromagnetic and magnetic survey, has unveiled several previously unidentified high-priority targets along a discrete 10-kilometre strike of the Teshierpi Fault Zone, the structural feature hosting the known Danvers mineralisation.

These newly identified targets exhibit magnetic signatures akin to the Danvers deposit, suggesting a continuous fluid pathway and the potential for multiple Danvers-style copper deposits. Notably, sulphide mineralisation intersected in drill hole DAN25019, located some 4 kilometres south of Danvers, confirms the fault’s mineralising potential beyond the immediate deposit area.

Historic Resource Review and Exploration Upside

Alongside the geophysical findings, White Cliff Minerals is preparing to release a review and digitisation of the historical resource at Danvers. Preliminary indications point to material upside beyond the historic deposit footprint, which was estimated at 4.16 million tons grading 2.96% copper. However, it is important to note that this historic estimate is not compliant with current JORC reporting standards and requires validation through modern drilling and assay protocols.

The company’s ongoing 2025 drilling campaign has already reported high-grade copper intervals, which will be used to fingerprint the geophysical signatures of mineralisation. This approach aims to enhance targeting precision for future drilling along strike and at depth.

Advancing Metallurgical and Processing Studies

White Cliff Minerals has commenced mineralogical studies, metallurgical test work, and scoping studies to determine the most effective methods for processing the copper-rich ores. These efforts include evaluating the suitability of the ore for direct shipping, a critical factor in project economics given the remote Arctic location.

Historical metallurgical data from the Danvers deposit indicates promising flotation characteristics with high copper recoveries and concentrate grades, but modern test work will be essential to confirm these findings under current processing standards.

Pending Assays and Next Steps

Assay results from sedimentary-hosted copper prospects, including the Hulk target, are currently undergoing final quality assurance and quality control signoff. These results, combined with the forthcoming airborne electromagnetic data, will complete the geophysical dataset and support the generation of a maiden exploration target in the coming months.

White Cliff Minerals plans to conduct a trial downhole electromagnetic survey at Danvers to assess the utility of EM methods in guiding future drilling campaigns. The integration of drilling data with geophysical surveys will be pivotal in refining exploration models and unlocking the Rae Copper Project’s full potential.

Bottom Line?

White Cliff Minerals’ latest geophysical data and ongoing studies set the stage for a pivotal exploration phase that could redefine the Rae Copper Project’s scale and value.

Questions in the middle?

  • How will the upcoming airborne electromagnetic data influence target prioritisation?
  • What are the timelines and expected outcomes for validating the historic Danvers resource under JORC standards?
  • Can metallurgical test work confirm the economic viability of direct shipping ore from this remote Arctic project?
