White Cliff Minerals Ltd. has revealed a high-grade copper discovery at its Rae copper project in Nunavut, Canada, confirming that the system extends far beyond previously known boundaries.
Assay results from regional expansion drilling at the Danvers prospect have identified a completely new, parallel mineralised zone outside the main Teshierpi Fault Zone.
The standout reverse circulation (RC) drillhole, DAN26015, intersected an exceptional 79.24-metre zone grading at 1.59 per cent copper from 67.06 metres, which included a high-grade core of 24.38 metres at 3.05 per cent copper from 120.4 metres. The results confirm that copper mineralisation is present on both contacts of the regional fault zone.
The company’s 2026 exploration campaign has rapidly scaled up the potential of the project. Assays have locked in a copper footprint exceeding 3.1 kilometres in strike length, while visual observations of copper sulphides stretch over a massive six kilometres. This represents more than half of the target’s total geophysical anomaly.
White Cliff Managing Director Troy Whittaker said the latest assays highlight the immense strength of the regional copper system.
“DAN26015 is an important result for White Cliff, confirming another high-grade copper discovery outside the main Teshierpi Fault Zone and demonstrating that mineralisation is not confined to a single structure,” Whittaker said.
“With high-grade copper now being discovered around an existing high-grade deposit… we believe Danvers is rapidly emerging as a much larger and more significant copper system than previously understood.”
To capitalise on the momentum, White Cliff has mobilised a second diamond drill rig to the site. This rig will focus on step-out drilling from the extraordinary ultra-high-grade intercept in hole DAN26012, which recently returned 19.81 metres at 6.64 per cent copper.
The diamond core drilling will also establish critical structural information to determine the true width and orientation of the newly found mineralisation.
Select diamond drillholes will be utilised with oriented core to determine vein orientations – this will inform future drilling orientations for step out and infill drilling.
The company will also continue further exploration along the Teshierpi Fault Zone.
