White Cliff Minerals (ASX:WCN): geophysics reveals regional copper potential in Nunavut

White Cliff Minerals (ASX:WCN) latest airborne geophysical survey across its Rae Copper Project in Nunavut, Canada, has substantially broadened the geological scope of the Danvers copper system, delineating several previously untested regional targets along the Teshierpi Fault Zone.

The new data underscore the scale potential of a district that has historically yielded some of Canada’s highest-grade copper intersections, positioning White Cliff for a new phase of data-driven exploration and model refinement.

Highlights

• Airborne survey identifies multiple high-priority targets along a 10km strike of the Teshierpi Fault Zone.

• Sulphides intersected 4km south of the known Danvers mineralisation confirm structural continuity.

• Digitisation of the historic Danvers resource is nearing release, with early analysis suggesting material upside.

• Metallurgical test work, mineralogical studies, and scoping studies now underway to determine optimal processing routes for copper-rich ores.

• Assay results from sedimentary prospects, including Hulk, are pending final QA/QC sign-off.

The survey’s magnetic results revealed a pronounced low associated with the Danvers deposit, extending along a northeast-southwest fault corridor interpreted as a key conduit for mineralising fluids.

This structure, part of the regional Teshierpi Fault Zone, has been mapped over 10 kilometres and remains largely untested by drilling.

Importantly, sulphide intersections encountered in drill hole DAN25019, some four kilometres to the south of Danvers, confirm the fault’s continuity and potential to host additional copper mineralisation of similar style and grade.

White Cliff Mineral’s Managing Director, Troy Whittaker, said the data point to the potential for multiple Danvers-style deposits along the same structure.

“These targets hold a similar magnetic signature, prove a continuous fluid pathway and are untested. These results, coupled with the ongoing release of assays, build and complete the data sets that will allow us to generate a maiden exploration target in the coming months.”

The airborne electromagnetic dataset, still pending at the time of reporting, is expected to further define conductive anomalies associated with copper sulphide systems.

The company also plans to undertake a trial downhole electromagnetic survey at Danvers to determine whether this method can effectively guide future drilling both along strike and down dip of the main breccia bodies.

White Cliff is concurrently finalising a digital model of the historic Danvers resource, originally defined in the 1960s.

Early reviews suggest that modern reinterpretation and integration of new geophysical datasets could materially expand the known footprint of the deposit.

The company is also preparing metallurgical and mineralogical test work programs to assess processing pathways and potential suitability for direct shipping of copper-rich material.

The Rae Copper Project already hosts an array of copper-silver occurrences across multiple geological settings, with historical drill results such as 175 metres at 2.5 per cent copper and 8.66 grams per tonne silver, and 90 metres at 4 per cent copper and 7.5 grams per tonne silver.

Together with its proximity to historic production centres along the Coppermine River, the project area represents one of Canada’s most prospective regions for sediment-hosted and iron oxide copper-gold (IOCG) mineralisation.

White Cliff Minerals’ systematic integration of geophysical and geological data at Rae marks an important step toward defining an exploration target of district scale.

The combination of structural confirmation, modern survey technology, and pending assay results from satellite prospects is expected to underpin a substantial update to the company’s exploration model.

While the historic Danvers resource remains non-JORC compliant, its re-evaluation within the broader Teshierpi corridor could reshape the company’s understanding of a copper system that has lain largely underexplored for decades.
