White Cliff Minerals (ASX:WCN) reports first-ever drilling at Bornite Hills has intersected more than 32m of bornite-dominant mineralisation within its Rae Copper Project in Canada.
Hole BNH26003 returned broad bornite-dominant mineralisation, including intervals of semi-massive bornite, 40m from surface below a historical trench that returned 3.66m @ 46.99% copper (Cu).
A second hole, BNH26001A, intersected 13.7m of bornite-chalcopyrite mineralisation in veins and breccias, confirming the system extends more than 60m below the historical surface occurrence.
Managing Director Troy Whittaker says the results confirm a new discovery at the target.
“We have intersected broad bornite-dominant mineralisation, including intervals of semi-massive bornite, more than 60m below a historic surface occurrence that returned 3.66m at 46.99% Cu,” Whittaker says.
“The mineralised structure remains largely untested across approximately 725m of prospective strike and at depth.”
The mineralisation is hosted by a north-north-west/south-south-east-trending fault structure cutting basalt, comprising quartz-carbonate veins, breccias, and copper sulphides dominated by bornite and chalcopyrite.
The structure sits on a subsidiary of the Herb Dixon Fault Zone, 32km from the Danvers area.
Eight additional diamond holes tested the redox boundary at the unconformity between the Rae Group and underlying basalts.
The 2026 drilling confirmed copper mineralisation at the base of the Rae Group several kilometres from 2025 discovery holes, extending the known footprint across more than 10km2.
The horizon now spans more than 4.3km east-west and 2.1km north-south, with drill spacing up to 2.6km leaving substantial untested areas.
Sander Geophysics has been commissioned to fly an ultra-high-definition magnetic, gravity, and radiometric survey over more than 70km of the Rae Group-Husky Creek Formation contact to refine basin architecture and major structures.
Two diamond rigs remain active at Danvers, completing infill and step-out drilling along the Teshierpi Fault Zone. Assay samples from Bornite Hills have been dispatched, with results expected in October 2026.
White Cliff Minerals is an Australian explorer focused on ‘high-grade’ copper and energy metals discoveries across tier-one jurisdictions.
