White Cliff magnetic survey reveals multiple Danvers-style targets at Rae copper project

• Airborne survey identifies multiple untested copper targets along 10km Teshierpi fault zone in Nunavut
• Magnetic signatures mirror those at the Danvers deposit, which hosts 45m of sulphides
• Upcoming work includes maiden exploration target release and downhole EM surveys

Special Report: Magnetic data from White Cliff Minerals’ airborne geophysical survey over the Danvers region within its Rae copper project in Nunavut, Canada, has identified several previously unknown high-priority targets.

These new targets extend along 10km of the Teshierpi Fault, within a structural setting and magnetic signature similar to known Danvers mineralisation.

The fault zone runs continuously down to hole DAN25019, where 45m of visually identified sulphides were previously reported about 4km southwest of the main Danvers deposit.

White Cliff Minerals (ASX:WCN) notes the magnetic low zones are untested by drilling and present as high priority exploration targets for future drilling.

“Preliminary results from the airborne magnetic survey have identified the potential for multiple Danvers style deposits along the length of the Teshierpi Fault Zone,” managing director Troy Whittaker said.

“These targets hold a similar magnetic signature, prove a continuous fluid pathway and are untested.

“These results, coupled with the ongoing release of assays, build and complete the data sets that will allow us to generate a maiden exploration target in the coming months.”

Rae project overview

The Danvers prospect is part of White Cliff’s Rae project, which hosts numerous high-grade copper mineralisation occurrences and hosts all first-order controls for a major sediment-hosted copper deposit.

Rae has a historical, non-JORC resource of 4.16Mt at 2.96% copper.

Whittaker notes the results are pending from the electromagnetic element of the airborne survey.

Once final airborne electromagnetic and magnetic data has been received, it will be filtered and integrated with data from mapping and drilling in 2025.

Notably, high-grade copper intervals from the drilling will be used to fingerprint the geophysical signature of mineralisation at Danvers, which can then be applied to search for analogous signatures along strike within the wider Teshierpi Fault Zone.

“A trial downhole electromagnetic survey is planned at Danvers to see if EM can guide future drilling along strike and down dip of the main mineralised breccia bodies,” Whittaker said.

Next steps

White Cliff noted that a review and digitisation of the Danvers historical resource is due for imminent release – and preliminary results from this work has already suggested material upside to the historical deposit footprint.

The company will now start mineralogical studies, metallurgical testwork and scoping studies to identify the best method for treating the copper-rich ores as well as suitability for direct shipping.

Assays are also pending from sedimentary prospects such as Hulk, which could deliver further upside to the Rae project’s growing resource potential.
