White Cliff Minerals (ASX: WCN) has identified a number of coincident anomalies to test at the at Danvers prospect within its Rae copper project in Nunavut, Canada.
The company unearthed the “multiple stacked high-tenor” copper targets – which it believes cover the entire 10-kilometre Teshierpi fault zone at Danvers – while processing data from a 2025 airborne electromagnetic (EM) survey.
Geophysical results have also identified replicating signatures along strike—the longest of which exceeds 1,500km, three times the size of the known Danvers mineralisation.
Only Lightly Tested
White Cliff has only phyically tested one of the anomalies at Danvers, with a single hole returning 15 metres at 4.8% copper and 20 grams per tonne silver from 12m, within a broader intersection of 30.5m at 2.5% copper.
Managing director Troy Wittaker said the latest high-grade copper and silver samples reinforce the outstanding grade potential and the possibility of another Danvers-style breccia system developing along the Teshierpi fault zone.
“This survey has transformed our understanding on the controlling mechanisms of the vein hosted mineralisation at Rae," Mr Wittaker said.
“The results clearly point to the potential for a materially larger mineralised system than previously recognised—several of the newly identified geophysical targets share the same signature as Danvers, yet exhibit footprints that are substantially larger in scale.
Historical Resource Review
The Danvers project – which White Cliff acquired in November 2024 – is host to a non-JORC compliant resource estimate of 4.16 million tonnes at 2.96% copper.
Earlier this year, the company conducted a review and digitisation of current and historical drilling and data at Danvers, with preliminary results providing enhanced geological confidence through more accurate 3D modelling, directly supporting the expansion of the project’s known copper mineralisation.
The same airborne EM survey that identified the high-priority targets also discovered the new Danvers 2 copper prospect several kilometres along trend from Danvers 1, returning 15m at 4.8% copper and 20g/t silver from 12m.
White Cliff plans to carry out mineralogical studies, metallurgical test work, and scoping studies to evaluate the best method for treating the copper-rich ores and their suitability for direct shipping.
