White Cliff Minerals Copper Discovery Confirms Major Danvers Expansion

White Cliff Minerals Deep Drilling Confirms Major Expansion of Danvers Copper Deposit

White Cliff Minerals (ASX: WCN; OTCQB: WCMLF) has delivered breakthrough results from its deep drilling program at the Danvers Copper Deposit within the Rae Copper Project in Nunavut, Canada. This White Cliff Minerals copper discovery has dramatically extended the deposit's known mineralisation both at depth and along strike, with copper mineralisation now confirmed to extend more than 60 metres below the deepest previous drilling.

Major Discovery Extends Danvers Footprint

The Company's systematic deep drilling programme has yielded exceptional results that fundamentally change the understanding of the Danvers deposit. Two key drillholes, DAN25020 and DAN25021, positioned approximately 160 metres apart, have successfully demonstrated the substantial depth potential of copper mineralisation at Danvers.

Key Drilling Highlights:

Furthermore, the drilling has confirmed copper mineralisation to 188 metres downhole and remains open at depth, indicating significant potential for further expansion.

Managing Director Commentary:
"These results indicate Danvers could be far larger than previously believed. Sustained and extensive copper mineralisation has now been confirmed more than 60m below the deepest drilling to date, extending from surface to a depth of ~200m. With recent geophysics paving the way for 2026, it's pleasing to see immediate validation from this recent drilling."

New Near-Surface Discoveries

Beyond the depth extensions, DAN25020 has also identified previously untested mineralised zones close to surface, coincident with adjacent geophysical anomalies:

• 9.14m @ 0.29% Cu from 13.72m
• 4.57m @ 0.18% Cu from 51.82m
• 4.57m @ 0.27% Cu from 70.1m

These near-surface discoveries occur outside the historic resource footprint and suggest the presence of additional breccia bodies that have never been systematically explored.

Understanding Sediment-Hosted Copper Deposits

Sediment-hosted copper deposits represent one of the world's most significant sources of copper, accounting for approximately 20% of global copper production. These deposits form when copper-bearing fluids migrate through porous sedimentary rocks, precipitating copper minerals in favourable geological environments.

Key characteristics include:

• Large tonnage, moderate to high-grade copper mineralisation
• Often contain significant silver by-products
• Typically occur in sequences of marine sedimentary rocks
• Examples include the Central African Copperbelt and European Kupferschiefer

Moreover, the Rae Project's geological setting, with its marine sedimentary sequences and proven copper mineralisation, presents compelling similarities to these world-class copper districts.

Expanding Regional Exploration Pipeline

The success at Danvers forms part of a broader systematic exploration approach across the 1,228 km² Rae Copper Project. Consequently, the Company holds an enviable position with multiple high-priority targets identified through recent geophysical surveys.

2026 Exploration Targets:

The 2025 HeliTEM survey has been particularly revealing, identifying Danvers I's distinctive geophysical signature – a magnetic low with IP effects and conductive EM response. Importantly, the survey has highlighted several targets with similar geophysical characteristics that are much larger and more conductive than the current Danvers deposit.

Strategic Value Proposition

This White Cliff Minerals copper discovery dual-pronged exploration strategy positions the Company uniquely in the Canadian copper exploration landscape:

1. Near-Term Value Creation

• Expanding the proven Danvers deposit with drill-confirmed mineralisation over 950m strike length
• Historic estimate of 4.16Mt @ 2.96% Cu covers only 375m of confirmed strike
• Recent drilling returning thicker and higher-grade intervals than historic work

2. District-Scale Discovery Potential

• Over 10km strike length of the favourable Teshierpi Fault Zone
• Multiple Danvers-type deposits possible along structural corridor
• Pipeline of drill-ready targets from comprehensive geophysical surveys

Financial Position:
With recent successful capital raising and strong cash position, White Cliff is fully funded for its aggressive 2026 exploration programme.

Why Investors Should Follow White Cliff Minerals

White Cliff Minerals has systematically built one of Canada's most compelling copper exploration stories through strategic acquisition and methodical exploration. For instance, the Company's position in the Great Bear Lake region – identified as having Canada's highest probability for hosting iron-oxide-copper-gold uranium mineralisation – provides exceptional leverage to copper price strength.

Key Investment Highlights:

Furthermore, the combination of proven resources, systematic exploration approach, and district-scale land position in a tier-one jurisdiction positions White Cliff as a compelling copper exploration investment.

What Makes This Discovery Significant?

The White Cliff Minerals copper discovery represents a paradigm shift in understanding the Danvers deposit's true potential. However, this is merely the beginning of what could be a much larger mineralised system.

The Company's methodical approach has revealed copper mineralisation extending far beyond previous estimates. In addition, the discovery of near-surface mineralisation outside the historic footprint suggests multiple breccia bodies remain unexplored.

How Does This Compare to Global Copper Deposits?

The White Cliff Minerals copper discovery exhibits characteristics similar to world-class sediment-hosted copper deposits. These include substantial strike lengths, multiple mineralised zones, and the potential for district-scale exploration success.

Consequently, the Rae Copper Project's geological setting mirrors that of proven copper districts worldwide. The combination of favourable geology, proven mineralisation, and systematic exploration creates a compelling exploration thesis.

Key Takeaway:
White Cliff Minerals has established itself as a leading Canadian copper explorer with a proven deposit that continues to grow and a pipeline of district-scale targets. With 2026 shaping up to be a defining year for the Company, investors seeking exposure to copper exploration upside should closely monitor WCN's systematic approach to unlocking value across the Rae Copper Project.

The Company's recent drilling success, combined with comprehensive geophysical targeting and full funding for aggressive exploration, creates a compelling investment thesis for copper-focused investors. As global copper demand continues to strengthen driven by electrification trends, White Cliff's proven Canadian copper assets offer significant leverage to sector fundamentals.

Could White Cliff Minerals Be Your Next Copper Investment Opportunity?

With copper mineralisation now confirmed to extend more than 60 metres below previous drilling and multiple high-priority targets identified for 2026 exploration, White Cliff Minerals presents a compelling opportunity for investors seeking exposure to Canadian copper exploration. The Company's systematic approach to unlocking value across the 1,228 km² Rae Copper Project, combined with full funding for aggressive exploration programmes, positions WCN as a standout play in the copper sector.
