Rae Copper Discovery
White Cliff Minerals reports first drilling discovery of copper mineralization at Rae project.
Anonymous
White Cliff Minerals reported first-ever drilling at Bornite Hills in its Rae Copper Project in northern Canada, intersecting visually logged zones of bornite-dominant mineralization, including more than 32 meters of mineralization in one hole and a separate 13.7-meter bornite-chalcopyrite zone. The mineralization lies more than 60 meters below a historical surface result grading 3.66 meters at 46.99% copper and remains open along roughly 725 meters of strike and at depth. The findings are based on visual core observations, with laboratory assays expected in October 2026, so the eventual grades and true widths remain unconfirmed. Separately, eight sediment-hosted holes expanded the known copper footprint to more than 10 square kilometers, though reported intercepts were generally modest and three holes had no significant mineralization. White Cliff has commissioned magnetic, gravity and radiometric surveys across more than 70 kilometers of the Rae Group–Husky Creek contact to refine its geological model and prioritize targets for 2027 drilling.
Key Points
1
Bornite Hills’ mineralization is hosted by a NNW–SSE-trending fault splay interpreted to branch from the Herb Dixon Fault Zone. The structure cuts basalt and contains composite quartz-carbonate veins, polymictic breccias and multiple generations of copper-sulphide-bearing fluid flow, dominated by bornite and chalcopyrite.
2
The visual logging table breaks down the headline Bornite Hills intersections: BNH26003 included intervals of 3.00m, 22.06m, 3.00m and 4.00m with visually estimated bornite of 0.1%–1% and chalcopyrite of up to 0.4%; BNH26001A included 11.50m at about 1% bornite and a 1.20m interval at 5% bornite with 1% chalcopyrite.
3
The sediment-hosted drilling expanded the mineralized footprint to approximately 4.33 kilometres east–west by 2.14 kilometres north–south. However, drill spacing reaches 2.6 kilometres between some holes, leaving substantial untested ground between confirmed intercepts and along the broader Rae Group–Husky Creek contact.

The regional geophysical program will be integrated with 2024 MobileMT data and 2025–2026 drilling results. Gravity data is intended to identify density contrasts and basement highs, while higher-resolution magnetic data will help map smaller structures and clarify basin architecture.
5
One Bornite Hills hole, BNH26002, ended at 15 metres before reaching its target depth and recorded no significant visual mineralization, underscoring that the initial drilling has not yet tested the target uniformly.
