Danvers 1 Copper Mineralisation Extended Over 950m with High-Grade Zones

• Digitisation of historic and recent drilling data completed
• Mineralised strike length at Danvers 1 increased by over 150% to 950m
• Continuity of copper mineralisation confirmed beyond 400m depth
• High-grade copper zones identified, enhancing project quality
• Regional targets along 10km Teshierpi Fault Zone show strong potential

Digitisation Unlocks New Scale at Danvers 1

White Cliff Minerals Limited has announced a breakthrough in its Rae Copper Project with the completion of a comprehensive digitisation and review of historic and recent drilling data at the Danvers 1 deposit in Nunavut, Canada. This effort, supported by Perth-based Terra Resources, has more than doubled the known mineralised strike length from 375 metres to over 950 metres, a 153% increase that fundamentally redefines the scale of the project.

The digitisation process involved integrating drilling data dating back to the 1960s with White Cliff’s 2025 drilling campaign and earlier work by Coronation Minerals. Detailed field validation and 3D geological modelling have enhanced confidence in the continuity of copper mineralisation, now confirmed to extend beyond 400 metres depth. This depth extension marks a significant step change, suggesting a robust and persistent copper system.

High-Grade Zones and Upside Potential

Alongside the expanded footprint, White Cliff’s recent drilling has identified thicker and higher-grade copper zones than previously reported. The system was historically modelled at a high 2% copper cut-off, and the new data indicates material upside potential even before formal resource re-estimation begins. Notable drill results include intervals such as 90 metres at 4% copper from surface and 175 metres at 2.5% copper at depth, underscoring the quality of the mineralisation.

Managing Director Troy Whittaker highlighted that these results exceed initial expectations and validate the company’s dual strategy of expanding the Danvers discovery while exploring sedimentary targets with regional-scale potential. The digitisation and drilling success position Danvers as a flagship growth asset within White Cliff’s portfolio.

Regional Exploration and Structural Targets

Beyond Danvers 1, recent geophysical surveys and drilling have identified a potential 4-kilometre mineralised structure along the Teshierpi Fault Zone, connecting Danvers 1 and Danvers 2. Assays from Danvers 2 include a standout 15 metres at 4.8% copper and 20 grams per tonne silver, indicating another high-grade copper system within the same structural corridor.

The company’s ongoing airborne electromagnetic and magnetics surveys, combined with the digitised drilling data, are refining high-priority drill targets along this 10-kilometre fault zone. These efforts support White Cliff’s plan to advance towards delivering a maiden JORC-compliant resource in 2026, a critical milestone for project valuation and development.

Historic Context and Compliance Considerations

The Danvers project was acquired by White Cliff Minerals in November 2024 and includes a historic, non-JORC compliant resource estimate of 4.16 million tonnes at 2.96% copper. While this historic estimate provides a foundation, the company cautions that further work is required to validate and potentially upgrade the resource under current JORC standards. The digitisation and new drilling data are key steps in this process.

White Cliff also holds the necessary permits and agreements, including a mineral lease with a 1% net smelter royalty held by Victoria Copper Inc., and permissions from local Indigenous groups and regulatory bodies, ensuring the project’s operational readiness.

Looking Ahead

With digitisation complete and encouraging drilling results in hand, White Cliff Minerals is poised to continue its exploration momentum at Rae. Upcoming assay results from the summer 2025 drilling campaign and final data from helicopter-borne electromagnetic surveys will further refine targets and resource estimates. The company’s strategic focus on both expanding high-grade discoveries and exploring sediment-hosted copper systems could unlock substantial value in this underexplored Canadian copper district.

Bottom Line?

White Cliff’s expanded footprint and confirmed depth continuity at Danvers 1 mark a pivotal step toward defining a major new copper resource in Nunavut.

Questions in the middle?

• How will pending assay results from recent drillholes impact the upcoming JORC resource estimate?
• What are the implications of the 1% net smelter royalty and buyback options on project economics?
• Can the regional exploration targets along the Teshierpi Fault Zone deliver additional high-grade discoveries?
