White Cliff Minerals (ASX: WCN) tests scale at Danvers ahead of assays

White Cliff Minerals Managing Director Troy Whittaker spoke with MarketOpen to further clarify the company’s latest drilling update at the Danvers prospect within its Rae Copper Project in Nunavut, Canada.

This discussion focuses on early results from the 2026 reverse circulation program, where visual copper sulphides have been intersected in all initial drillholes across a defined strike extent. With drilling stepping out materially from the known deposit and extending into the broader structural system, the update moves the narrative from a single discovery area toward a larger mineralised corridor now being tested. The immediate focus shifts to assay results, which will determine how these observations translate in economic terms.

What has this five from five visual sulphide outcome materially changed in your view of the Danvers system scale and how does it shift your exploration priorities across the broader structure?

This outcome has shifted our understanding of the scale and consistency of mineralisation at Danvers. In the first five holes of the program, we have intersected visual copper sulphides in every hole, confirming mineralisation across multiple step out positions rather than a single localised zone.

Importantly, the first hole was collared more than 5.2km from the Danvers 1 deposit and still intersected sulphides, which supports our view that mineralisation extends beyond the immediate footprint of the known deposit.

In practical terms, this directs our focus toward testing the broader structure and the extension of the Danvers trend. We are prioritising drilling across this corridor, guided by geophysical datasets, to understand how mineralisation develops through the system as the program progresses.

How are you sequencing the current drilling program across the more than 12km of identified strike to ensure capital is directed toward the highest probability zones of continuity and scale?

We are sequencing the program along the main structure using a disciplined step out approach, guided by geophysical datasets to prioritise target areas. Our current focus is the Teshierpi Fault Zone, where drilling is testing more than 8km of strike, alongside the greater than 4km extension of the Danvers 1 trend.

Targets are selected based on EM and magnetic responses that align with known mineralisation, allowing us to focus drilling on defined anomalies rather than broader regional areas.

As the program progresses, observations from each hole are used to refine subsequent drill locations, ensuring capital is directed toward areas that continue to demonstrate consistent indications of mineralisation within the broader system.

To what extent do these step out results and deeper visual observations reduce geological risk, and what key uncertainties remain until assay results are received?

These results reduce geological risk by confirming that visual copper sulphides are present across multiple step out holes, including the first hole collared more than 5.2km from the Danvers 1 deposit. They also show mineralisation extending across multiple drill positions and being identified beyond 200m vertical depth, including new zones within the Teshierpi Fault Zone.

This supports the exploration model being applied across the structure and demonstrates that mineralisation is not limited to a single location.

The next step for White Cliff Minerals is confirming grade through assay results. The company has stated that visual estimates should not be considered a substitute for laboratory analysis, and until assays are received, the widths and grades of the observed mineralisation cannot be determined.

Execution now moves to validation and continuity

The program remains at an early stage, with current work focused on validating the observed mineralisation through assay results and continuing drilling along the identified structural corridors. Drilling is ongoing, with further holes planned to test the broader strike of the Teshierpi Fault Zone and extensions of the Danvers trend.

The near term sequence centres on assay results, followed by continued drilling to assess how mineralisation presents across the system. From here, the focus remains on progressing the program in a structured manner, using each stage of data to guide subsequent work.
