White Cliff Minerals Unveils 4km Copper Sulphide Trend at Danvers Project

Expanding the Copper Footprint

White Cliff Minerals Limited (ASX – WCN) has announced a major step forward in its exploration of the Danvers Copper Project in Nunavut, Canada. Recent reverse circulation drilling has revealed broad intervals of copper sulphide mineralisation extending over a remarkable 4-kilometre strike length along the Teshierpi Fault Zone. Notably, drillhole DAN25019 intercepted 45 metres of copper sulphides starting just 12 metres below surface, underscoring the project's potential scale.

Further drilling has expanded the Danvers mineralised zone to an 830-metre strike length, with mineralisation remaining open in all directions. This expansion builds on earlier results, including a 65-metre sulphide intercept from drillhole DAN25013, located 150 metres southwest of a previous hole. The continuity and width of these sulphide zones suggest a robust copper system that warrants continued exploration.

New Structures and Regional Potential

In addition to extending known mineralisation, White Cliff has uncovered a previously unknown parallel structure adjacent to Danvers. Drillholes DAN25016 and DAN25017 intersected 8 and 17 metres of sulphide mineralisation respectively within this new zone, which remains largely untested. This discovery hints at a more complex and extensive copper system than previously understood.

Meanwhile, diamond drilling has commenced at the Hulk and Stark targets, also within the Rae Copper Project area. These efforts aim to delineate sediment-hosted copper mineralisation styles that complement the breccia-hosted systems at Danvers, potentially tying together a larger regional copper play.

Historic Context and Future Outlook

The Danvers prospect benefits from a rich exploration history, including a historic resource estimate of approximately 4.16 million tons grading 2.96% copper. However, this estimate predates modern reporting standards and is not compliant with the JORC Code. White Cliff Minerals is actively working to validate and upgrade this historic data through ongoing drilling and assay programs, with initial assay results expected in the September quarter.

Complementing the drilling, extensive geophysical surveys conducted in 2024 have provided a framework for targeting and understanding the mineralisation controls. The company’s methodical approach, including rigorous sampling and quality control protocols, aims to deliver a maiden JORC-compliant mineral resource estimate in due course.

Balancing Optimism with Caution

While visual observations of sulphide mineralisation are encouraging, White Cliff Minerals emphasizes that these are preliminary indicators. Definitive conclusions await laboratory assay results, which will clarify the grade and economic potential of the mineralised zones. The company also acknowledges the need to better understand true thicknesses and the spatial continuity of mineralisation to refine resource models.

Managing Director Troy Whittaker highlighted the significance of the findings, stating that the combination of wide intervals, high-grade visual sulphides, and the extension of Danvers to over 800 metres strike length is very encouraging. He expressed confidence that ongoing drilling will integrate Danvers into a broader regional copper system, potentially elevating the Rae Copper Project’s profile in the global copper exploration landscape.
