White Cliff Minerals Drilling Campaign Expands Rae Copper Project

White Cliff Minerals Ramps Up Major Drilling Campaign at Promising Rae Copper Project

White Cliff Minerals (ASX: WCN) has announced plans to re-commence exploration activities at its Rae Copper Project in Nunavut, Canada. Furthermore, the company has outlined an ambitious White Cliff Minerals drilling campaign for 2026, targeting significant scale expansions across its high-grade, near-surface copper system.

The announcement represents a major step-up in exploration scope, with drilling activities planned to demonstrate mineralisation over an 8km strike length. This marks a substantial expansion from the 950m of strike already defined at the Danvers deposit.

Exceptional 2025 Results Set Stage for Regional Expansion

The 2026 program builds on outstanding results from White Cliff's White Cliff Minerals drilling campaign at Danvers, which delivered some of the most impressive copper intercepts seen in recent exploration activities. The results demonstrate the potential for significant copper discoveries across the broader region.

These results demonstrate both the high-grade nature and near-surface accessibility of the Danvers system. Notably, the standout DAN25005 hole intersected significant copper mineralisation directly from surface.

In addition, a single regional exploratory drillhole 4km southwest of Danvers returned 15.24m @ 4.8% Cu and 20g/t Ag from just 12m depth. This confirms the fertility and regional potential of the Teshierpi Fault Zone.

Strategic Infrastructure Advantages Reduce Costs

White Cliff has established significant operational advantages that position the company for cost-effective exploration. These infrastructure improvements demonstrate the company's commitment to efficient resource development.

• On-site diamond rig already positioned and ready to commence drilling
• Operational airstrip commissioned during 2025 campaign
• Established camp facilities at Rae, dramatically reducing mobilisation costs
• Experienced drill crew familiar with ground conditions returning from 2025 program

"The 2025 campaign was definitive not only from a results point of view, it allowed us to bring our airstrip on line and to mobilise and establish the Camp at Rae, greatly reducing mobilisation costs this year… 2026 is shaping up as an exciting time for White Cliff"

— Troy Whittaker, Managing Director

Understanding Copper Grade Significance

What makes these copper grades exceptional?

The copper intercepts at Danvers are particularly impressive when viewed against industry benchmarks. Copper grades above 2% are considered high-grade in most global contexts. Moreover, grades exceeding 4% (as seen in DAN25005) are truly exceptional.

For comparison, many of the world's major copper operations work with grades between 0.5-1.5% copper. However, White Cliff is encountering multiple intercepts above 2% copper, with several exceeding 3-4%. This demonstrates the exceptional tenor of the Danvers system.

The near-surface nature of this mineralisation adds another layer of significance. High-grade copper starting from surface or shallow depths dramatically improves the economics of any future development scenario.

Copper's Critical Role in Energy Transition

Copper demand is projected to grow significantly due to electrification trends and renewable energy infrastructure requirements. Electric vehicles contain approximately four times more copper than conventional vehicles. Furthermore, renewable energy systems require substantial copper wiring and components.

This fundamental demand shift makes high-grade copper discoveries increasingly valuable for investors. Consequently, investors are seeking exposure to the energy transition through strategic mineral investments.

2026 Drilling Program: Scale and Scope

Phase 1: Danvers Regional Expansion

The White Cliff Minerals drilling campaign will commence with an RC drilling program targeting 8km strike length along the Teshierpi Fault Zone. The program will focus on high-priority geological/geophysical targets identified through 2025 surveys.

Additionally, follow-up drilling will test the 15m @ 4.8% Cu regional discovery. This approach demonstrates the systematic expansion of exploration activities across the broader project area.

Phase 2: Sediment-Hosted Copper System

Diamond drilling will target the 1.7km long sediment-hosted copper mineralisation at Stark and Hulk. The program will test the Eastern Sedimentary Basin adjacent to the Herb Dixon Fault.

This phase offers potential for large-scale sediment-hosted copper deposits. Such deposits could significantly expand the overall resource potential of the project.

Mobilisation Timeline

RC rig deployment commencing this month from Yellowknife will initiate the exploration program. The enhanced drilling capacity includes a rig now capable of >250m depths.

Diamond drilling will commence approximately 6 weeks after the RC program begins. This staged approach ensures efficient resource allocation across both exploration phases.

Geophysical Targeting Identifies Multiple High-Priority Targets

White Cliff's 2025 geophysical surveys have identified compelling drill targets through multiple lines of evidence. The integration of various geophysical techniques has enhanced target definition significantly.

Key Geophysical Signatures:
• Hematite alteration creating linear magnetic lows
• Elevated conductivity indicating potential sulphide mineralisation
• Induced polarisation effects from airborne electromagnetic surveys
• NE/SW structural trends paralleling the main Teshierpi Fault Zone

The integration of these geophysical signatures has identified numerous areas where low magnetic response, peak conductivity, and induced polarisation effects occur together. This creates compelling targets for Danvers-style mineralisation.

Investment Thesis: Why This Matters

Scale Potential

The 2026 White Cliff Minerals drilling campaign represents a potential step-change in the scale of White Cliff's copper discovery. Moving from 950m of defined strike to testing 8km of prospective ground could dramatically expand the resource potential.

High-Grade, Near-Surface System

The combination of exceptional grades and near-surface accessibility positions any discovery for attractive development economics. This is particularly important in the current copper market environment.

Regional Fertility Confirmed

The 4.8% copper hit 4km from Danvers proves the Teshierpi Fault Zone hosts district-scale copper potential. This extends well beyond an isolated deposit, indicating broader exploration opportunities.

Dual Deposit Styles

White Cliff is simultaneously pursuing two distinct mineralisation styles. Danvers-style epithermal copper-silver deposits offer high-grade potential. Meanwhile, sediment-hosted copper systems provide Central African Copperbelt analogies for large-scale deposits.

Market Context: Copper's Strategic Importance

The timing of White Cliff's expanded drilling program aligns with growing recognition of copper's critical role. The global energy transition creates unprecedented demand for copper resources.

Copper demand is projected to grow significantly due to electrification trends and renewable energy infrastructure. Consequently, high-grade copper discoveries are increasingly valuable to investors and resource companies.

The Canadian jurisdiction provides additional investment appeal. It offers stable mining regulations and established mining infrastructure in a tier-one jurisdiction.

What Makes This Drilling Campaign Different?

Advanced Infrastructure Foundation

Unlike typical exploration campaigns, this White Cliff Minerals drilling campaign benefits from established infrastructure. The operational airstrip and camp facilities significantly reduce mobilisation costs and operational complexity.

Multi-Target Approach

The program simultaneously tests multiple geological environments and deposit styles. This diversified approach maximises discovery potential while spreading exploration risk across various target types.

Proven Ground Conditions

The 2025 results provide confidence in the geological model and targeting approach. Furthermore, the experienced drill crew returns with knowledge of local ground conditions and optimal drilling techniques.
