White Cliff Minerals doubles copper strike length at Danvers in Canada

• Recent drilling has confirmed extensive zones of mineralisation at Danvers
• Results from a drone-based MT survey have also been received
• White Cliff plans to use both set of results to guide and map follow up drilling over the entire 10km strike at Danvers

Special report: White Cliff Minerals has delivered a strong start to its summer drilling campaign at the Rae copper project in Canada, with assays at the Danvers prospect more than doubling strike and revealing thick copper zones.

The explorer says the latest update is just the beginning of what will be a steady flow of results from both Danvers and the Rae sedimentary targets over the coming months.

While delays in reporting were caused by a busy northern summer exploration season and a land rush in Nunavut sparked by White Cliff’s (ASX:WCN) standout 2024–2025 results, the first assays have been worth the wait.

Hole DAN25010, drilled as a blind step-out about 100m northeast of the impressive DAN25002 hit (63m at 2.2% copper), returned 12.2m at 2.0% copper from just 15m depth, within a broader 34m zone grading 1.02% copper.

A second interval starting from 53m remains open downhole, with more assays still to come.

Importantly, this mineralised zone now appears to sit on the edge of a newly recognised large conductor, interpreted as the main Danvers lode that has been offset roughly 200m along a fault.

The second hole, DAN25013, was drilled about 200m southwest along strike from DAN25007, which itself delivered a standout hit of 105m at 2.25% copper.

It also hit multiple zones of copper mineralisation, including 49m at 1.33% copper from 74.68m with a rich section grading 6.6% copper and nearly 24g/t silver over 3m from 88.39m.

Survey results to guide next drilling strategy

Results have also come in from a high-resolution drone-based MobileMt survey, which not only mapped the geophysical footprint of the historical Danvers resource, but also identified repetitions of that same signature along the broader Danvers corridor.

Several large, previously blind structures have popped up, sitting right near White Cliff’s current drill targets, which could be copper-rich.

The survey has also uncovered a series of undrilled parallel anomalies within the Teshierpi Fault Zone, suggesting that earlier drilling may have missed the thick, high-grade cores of mineralisation due to strike-slip displacement.

With new geophysics in hand, White Cliff says future drilling will be far better positioned to home in on those richer zones.

On top of that, XCalibur Smart Mapping has wrapped up a detailed heliTEM survey over the Danvers lease, producing high-resolution magnetic and EM datasets, with additional lines flown over the Rae sediments, and results from that are expected within days.

Meanwhile, digitisation of the historical Danvers drilling is almost complete, with those results set to further sharpen the company’s next drilling strategy.

Drone and heliTEM unlock new layer of copper potential

WCN managing director Troy Whittaker says the drill results, integrated with the detailed drone-based MT data, clearly shows the findings occur on the outer edge of the newly identified massive conductive anomaly, which appears structurally offset from the previously interpreted linear main SW-NE Danvers structure.

“This MT data, alongside the results from the heliTEM survey (due in the coming weeks), the first of its kind over Danvers, will bring outstanding geophysical resolution and will allow us to map and prioritise follow up drilling over the entire 10km Danvers strike,” Whittaker said.

“Following from our remarkable 2024 year as sole operators in the region, we are now seeing up to four concurrent drill campaigns at any one time placing extra demand on assay services in the current period resulting in the standard assay process period being extended to an average of [more than] nine weeks.”
