White Cliff Minerals (ASX:WCN) has confirmed a new ‘high-grade’ copper discovery outside the main Teshierpi Fault Zone at its Rae Copper Project in Nunavut, Canada.
Drill hole DAN26015 returned 79.24m @ 1.59% copper from 67.06m, including 24.38m @ 3.05% copper from 120.4m, confirming mineralisation on both contacts of the regional fault zone.
The company says 2026 assay results now confirm a footprint exceeding 3.1km in strike length, with visual observations extending more than 6km along strike.
Managing Director Troy Whittaker says DAN26015 is an ‘important result for White Cliff’.
Simultaneously, the hole confirms a new ‘high-grade’ zone of copper mineralisation outside the main Teshierpi Fault Zone, indicating that the system extends beyond the current structure.
“We are now seeing copper zones expanding materially around Danvers 1, with new drilling extending the system 462m to the southwest, 686m to the northeast, and identifying a parallel mineralised zone 606m to the north at DAN26022,” Whittaker adds.
“These results are being delivered from wide-spaced drilling into largely untested ground, which speaks directly to […] the strength of the Teshierpi copper system and the effectiveness of our targeting.”
The company reports that copper sulphides are now observed over a strike length of more than 6km within the main Teshierpi Fault Zone between DAN26001 and DAN26024.
DAN26020 has extended known mineralisation at Danvers 1 by 215m to the southwest from 2025 hole DAN25015, consisting of 30m of combined sulphides in veins and blebs within amygdaloidal and massive basalts.
White Cliff Minerals has deployed a second diamond drill rig on site to target step out from ‘ultra high-grade’ mineralisation at DAN26012, which returned 19.81m at 6.64% copper.
The Rae Copper Project comprises 93 mineral claims in three blocks and one mineral lease covering 1,228km2 in the Kitikmeot region of Nunavut.
The project contains a historic resource estimate at Danvers of 4.16 million tons at 2.96% copper.
