The White Cliff Minerals Canadian drilling campaign represents one of the most significant copper exploration programmes set to unfold in 2026, as the company mobilises resources for an ambitious expansion of its breakthrough sediment-hosted copper discovery. With the first supply flight successfully landing at the remote Rae Copper Project in Nunavut, Canada, drilling operations are poised to commence within weeks, marking a pivotal moment for the company's exploration strategy.
Camp Restart Signals Ambitious Drilling Programme
White Cliff's local partner Aurora Geosciences has successfully delivered drilling consumables and camp supplies to the Rae project site, with camp restart now fully underway. The systematic approach reflects the company's commitment to expanding upon its 2025 breakthrough discovery of high-grade sediment-hosted copper mineralisation.
Key 2026 Drilling Timeline:
- RC drilling at Danvers: Commencing in coming weeks
- Diamond drilling of sedimentary targets: Beginning approximately 4 weeks after RC drilling starts
- Target area: 8km Teshierpi Fault Zone expansion
- Initial focus: Stark-Hulk basin covering 60km² within broader 100km² target area
The phased approach allows White Cliff to systematically test both volcanic-hosted copper at Danvers and the newly identified sediment-hosted copper system. Furthermore, this methodology ensures optimal resource allocation whilst maximising discovery potential across multiple target areas.

High-Grade Discovery Validates Exploration Strategy
The company's confidence stems from 2025 drilling success at Stark, which confirmed high-grade copper mineralisation with 3.5m @ 7.2% Cu within a broader intercept of 12m @ 2.45% Cu from 287m depth. This discovery validated White Cliff's basin-hosted copper exploration model and identified 4.3km of north-south strike along the Herb Dixon Fault.
Managing Director Troy Whittaker commented:
"Initial drilling at Stark confirmed a high-grade sedimentary-hosted copper discovery, highlighted by 3.5m at 7.2% Cu within 12m at 2.45% Cu from 287m, validating the Company's basin-hosted copper exploration model. These results have identified a large, untested conductive anomaly, significantly refining the search space and delivering a high-priority drill target for 2026."
Geological investigation indicates the mineralisation is associated with major basin-scale structures, particularly the Herb Dixon Fault, interpreted as a key conduit for copper-bearing hydrothermal fluids. In addition, this structural control provides valuable insight into potential target areas for future exploration phases.
Understanding Sediment-Hosted Copper Deposits
What are sediment-hosted copper deposits?
Sediment-hosted copper deposits represent one of the world's most significant sources of copper, including famous districts like the Central African Copperbelt and European Kupferschiefer. These deposits form when copper-bearing fluids migrate through sedimentary basins, depositing copper sulfides at favourable geological interfaces.
Key characteristics:
- Formation at redox boundaries between different rock types
- Association with major structural corridors (faults)
- Potential for large, continuous mineralised zones
- Often contain significant silver by-products
Why this matters for investors
Sediment-hosted copper deposits can host substantial tonnages at economic grades, making them highly attractive exploration targets in today's copper supply-constrained market. These systems typically demonstrate excellent continuity and scale potential, offering the prospect of developing significant resources from successful exploration programmes.
The discovery at Stark demonstrates classic sediment-hosted copper characteristics, with pyrite within the sediments replaced by chalcopyrite. Additional chalcopyrite disseminated within the sediments, and crosscutting veinlets. Consequently, later quartz-calcite-chalcopyrite veins crossed both the basement and Rae Group sediments, indicating multiple episodes of copper mineralisation.
Extensive Geophysical Foundation Supports 2026 Programme
White Cliff has built a comprehensive geophysical database to guide its 2026 drilling efforts. However, the company's systematic approach to data collection ensures maximum confidence in target selection and drilling programme design.
Completed Surveys:
- 2,427 line-km MobileMT airborne geophysics (2024)
- 177 line-km drone-based mobile Magneto-Telluric survey (2025)
- Helicopter-borne electromagnetic/magnetic survey (2025)
The integrated geophysical datasets have identified extensive prospective sedimentary horizons across the Rae Basin. Furthermore, these surveys revealed multiple untested targets showing significant strike potential for sedimentary-hosted copper mineralisation.
Critical Discovery: The surveys revealed a large, untested conductive anomaly adjacent to the 2025 discovery area. For instance, this represents a high-priority target that could indicate greater sulphide concentrations within the basin.
Strategic Drilling Approach Targets Scale and Grade
The White Cliff Minerals Canadian drilling campaign employs a systematic approach designed to define the scale, continuity, and grade potential of what appears to be a major copper system:
Phase 1: Regional Expansion
- Wide-spaced drilling grid to test extensions east and north of known mineralisation
- Targeting the untested electromagnetic conductivity signature
- Focus on Stark-Hulk sub-basin systematic evaluation
Phase 2: Follow-up
- Infill drilling of any significant mineralisation
- Regional drilling along NW trending Rae Group unconformity
- Testing multiple high-priority targets identified to date
Target Rationale:
The strategy recognises that sediment-hosted copper exploration typically requires wide-spaced drilling to delineate mineralisation extremities. Subsequently, systematic infill follows to define grade and tonnage potential. The electromagnetic signature located in an untested part of the basin is a priority target, as it is adjacent to an area of drill confirmed mineralisation and may represent a greater concentration of connected sulphide minerals.
