White Cliff Minerals (ASX:WCN) defines new high priority copper targets at Danvers

White Cliff Minerals has released the independently processed results of its 2025 airborne electromagnetic survey over the Danvers area of the Rae Copper Project in Nunavut, confirming new high priority copper targets that align closely with recent drilling and surface assays along strike.

The results arrived later in the year because of mid-season survey completion and the additional processing time required, but they now provide the most detailed view to date of the structural and geophysical signatures associated with the basalt hosted vein mineralisation at Danvers.

Highlights

• Results recently received due to mid-season survey completion and extended processing time

• Multiple stacked high tenor copper targets identified across the entire 10km Teshierpi Fault Zone

• Only two anomalies tested to date, including DAN25019 which returned 15m @ 4.8% Cu and 20g/t Ag within a broader 30.5m @ 2.5% Cu from 12m

• Replicating signatures identified along strike, the largest exceeding 1,500m in length at approximately ±3 times the size of known Danvers mineralisation

• Grab samples between DAN25019 and Danvers returned 37.4% Cu and 72.9g/t Ag, 25.8% Cu and 39.7g/t Ag, 16.5% Cu and 21.5g/t Ag, and 11.4% Cu and 20.4g/t Ag

• Follow up drilling scheduled to commence early 2026

The newly completed interpretation integrates electromagnetic, magnetic and gravity datasets, all back tested against mapping, rock chip sampling and confirmatory drill results.

This allowed the company to refine the electrical signature associated with basalt hosted vein mineralisation and apply that signature across the broader Teshierpi Fault Zone.

The survey outlines multiple overlapping zones where low magnetic response, peak conductivity and induced polarisation effects coincide, forming robust targets with similar geophysical characteristics to Danvers.

One of the most notable areas lies between DAN25019 and the Danvers breccia system, where grab samples returned exceptionally high copper and silver values, dominated by chalcocite.

These samples come from replaced basalt flow top horizons, a feature consistent with the replacement style mineralisation located immediately adjacent to the main Danvers vein and breccia zone.

White Cliff Minerals Managing Director, Troy Whittaker stated:

“This survey has transformed our understanding on the controlling mechanisms of the vein hosted mineralisation at Rae. We have multiple high-quality drill ready, ground truthed, targets of coincident EM, magnetics and gravity anomalies. Exactly the sort of signature we see at Danvers and multiples larger in size.”

The survey also confirms that DAN25019 was drilled on the outer edge of the largest conductor identified so far, indicating that the main part of the conductor remains untested.

Several newly identified anomalies match the Danvers geophysical pattern but at significantly larger scale, with the largest extending beyond 1,500m, expanding the exploration footprint for both basalt hosted and sediment hosted copper systems within the project area.

With assay results from the company’s sediment hosted copper targets still arriving and the full dataset from the new helicopter-borne EM survey now integrated, White Cliff Minerals enters the 2026 drilling season with clearer definition of mineralising pathways, refined geophysical vectors and multiple drill ready targets.

The expanded footprint at Danvers and the confirmation of high grade chalcocite samples provide a broader context for the next phase of drilling, which will test several untested conductors exhibiting the same key geophysical attributes as the known mineralisation.
