White Cliff Minerals (ASX:WCN | OTCQB:WCMLF ) expands copper potential at Danvers with strong assays and modern geophysics

White Cliff Minerals (ASX:WCN; OTCQB:WCMLF) has announced the first batch of assay results from its 2025 summer drilling campaign at the Danvers prospect within the Rae Copper Project in Nunavut, Canada.

The assays more than doubled the strike extent of copper mineralisation and revealed thick, high-grade zones, while new geophysical surveys identified large undrilled conductors that may represent the main Danvers lode.

To provide clarity on what these developments mean for the Company and its shareholders, Managing Director Troy Whittaker addressed five key investor questions.

What do these assay results mean for the scale of the Danvers discovery?

The results from this drilling program demonstrate that the mineralised system is extending beyond previous boundaries and remains open for growth.

Drillhole DAN25013 intersected 49 metres at 1.33% copper from 74.68 metres, including 3 metres at 6.6% copper and 23.95 grams per tonne silver from 88.39 metres, while DAN25010 delivered 33.53 metres at 1.02% copper from 15 metres, including 12.2 metres at 2% copper.

“These results are very important for us because they demonstrate that the Danvers system is larger and more continuous than previously thought. What makes this significant is that these results have more than doubled the known strike length of mineralisation along the Danvers trend, and we are now confirming that extensive zones of copper exist outside the boundaries of the historic resource.”

Why was there a delay in releasing these results?

Laboratory backlogs across Nunavut caused the delay, as assay services were placed under considerable pressure during the peak exploration season.

Increased drilling activity across the region, following White Cliff’s own discoveries in 2024 and early 2025, extended turnaround times to more than nine weeks.

Despite these challenges, the Company is now releasing results and expects further assays to flow steadily from both the Danvers trend and sedimentary copper targets in the Rae Project.

“The Northern Hemisphere summer is the peak exploration season, and this year we saw a large increase in drilling across Nunavut following our own discoveries in 2024 and early 2025. That has put considerable pressure on assay services, with turnaround times stretching to more than nine weeks.”

What do the geophysical surveys add to your understanding of the project?

The application of modern geophysics has transformed the Company’s view of the subsurface.

A drone-based Mobile MT survey revealed that mineralisation encountered in the recent drilling lies on the edge of a large conductive anomaly, which is interpreted as the main Danvers lode.

“The Mobile MT survey revealed that the mineralisation intersected in our drillholes sits on the outer edge of a newly identified large conductive anomaly, which represents the main Danvers lode and appears to be offset by around 200 metres due to faulting. In simple terms, this means that the strongest part of the system remains undrilled.”

Several blind anomalies have also been identified within the Teshierpi Fault Zone, and the helicopter-borne heliTEM survey, flown at 100 metre line spacing, is expected to provide further high-resolution electromagnetic and magnetic coverage when results are received in the coming weeks.

How does this fit into the overall Rae Project strategy?

Danvers has double value when it comes to the Rae Copper Project, which already contains a historic resource estimate of 4.16 million tonnes at 2.96% copper.

Danvers, with its increasing tonnage, and from surface allows a potential simple start up DSO operation.

The assays, together with new geophysical data, confirm that Danvers hosts the right geological setting for a copper system with multiple mineralised centres.

“The assays from this release, combined with the geophysical results, confirm that we are dealing with a large mineralised system with the right geological setting for the type of copper deposits. Strategically, it means Danvers is shaping up as an opportunity in its own right with multiple mineralised centres. The upside is the massive potential in the sedimentary system.”

The combination of historic work, strong new drill results and modern exploration methods is allowing White Cliff to significantly expand the potential of the project beyond its historic boundaries.

What are the next steps following this announcement?

White Cliff Minerals is integrating the new assay results with the Mobile MT and forthcoming heliTEM survey data to refine drill targeting.

Additional assays are pending from other holes, and the digitisation of historic drilling is close to completion, which will add further depth to planning.

“The immediate next step is to integrate these new drill results with the geophysical data so that we can refine our targeting. We have additional assay results pending from other holes, and data from the heliTEM survey is due in the coming weeks.”

Future drilling will prioritise testing the undrilled conductor identified to the northwest of current holes, while also stepping out to investigate new anomalies in the Teshierpi Fault Zone.

Looking ahead

The combination of strong assay results and modern geophysics has reinforced the scale and potential of the Danvers discovery.

White Cliff Minerals is now positioned to advance exploration across the 10 kilometre strike with greater precision.

As more assays and survey results are received, the Company will refine its targets and systematically test new zones to build on the momentum of this campaign.
