58m at 3.08% Cu and 18m at 5.21% Cu Highlight White Cliff’s Rae Drilling Debut

Strong Start to Maiden Drilling Campaign

White Cliff Minerals Limited (ASX: WCN) has announced the first assay results from its maiden reverse circulation (RC) drilling campaign at the Rae Copper Project in Nunavut, Canada. The highlight comes from drill hole DAN25003, which intersected 58 meters grading 3.08% copper and 13.3 grams per tonne (g/t) silver starting at 52 meters depth. Within this, an 18-meter high-grade zone returned 5.21% copper and 22.33 g/t silver, underscoring the project's potential for significant copper mineralisation.

These results mark a pivotal moment for White Cliff, confirming the presence of high-grade copper mineralisation downhole and complementing previously reported remarkable surface rock chip assays. Managing Director Troy Whittaker emphasised the importance of these findings as a foundation for further exploration and resource development.

Advancing Exploration at Danvers and Hulk Targets

The Rae Copper Project encompasses multiple targets, including the Danvers area where the initial drilling is focused, and the Hulk sediment-hosted copper target. Pre-collar drilling at Hulk is progressing well, with three holes drilled to depths of approximately 180 meters. This preparatory work is designed to facilitate a swift transition to diamond drilling, targeting the massive sedimentary copper horizons that are key to the project's upside potential.

White Cliff's exploration strategy integrates detailed geological mapping, field sampling, and a comprehensive 2,427 line-kilometer MobileMT airborne geophysical survey completed in 2024. These efforts aim to refine target areas and enhance the understanding of the mineralisation controls within the Rae Group sediments and Copper Creek Formation basalts.

Historic Context and Resource Potential

The Rae Copper Project sits within a region historically known for high-grade copper occurrences, with a historic resource estimate of 4.16 million tons at 2.96% copper reported from the Danvers Prospect. While this estimate predates modern JORC standards and requires verification through ongoing drilling and assay work, it provides a valuable benchmark for the project's scale and grade potential.

White Cliff Minerals has acquired 100% ownership of the project, including a mineral lease from Victoria Copper Inc., which retains a 1% net smelter royalty. The company holds all necessary permits and agreements with local Indigenous groups, ensuring a clear path for continued exploration activities.

Technical Rigor and Forward-Looking Plans

The announcement includes extensive JORC-compliant technical data, detailing sampling techniques, assay methods, and quality control protocols. Assays were conducted by ALS Laboratories using near-total digestion methods and multi-element ICP-MS analysis, ensuring robust and reliable results.

Looking ahead, White Cliff plans to continue drilling at Danvers and Hulk, with further assay results expected in the coming weeks. The company also intends to reassess geophysical data in light of new drilling information and conduct detailed surface sampling campaigns to expand the understanding of the mineralised system.

While the initial results are promising, the true thickness and continuity of mineralisation remain to be fully established. Metallurgical and environmental studies are also pending, which will be critical to advancing the project towards development.
