White Cliff (ASX:WCN) lays eyes on widespread Nunavut copper strike

White Cliff Minerals has established the presence of multiple styles of copper mineralisation through initial fieldwork over its Rae project, providing the potential for a district-scale asset in Canada’s Nunavut territory.

First eyes over the copper-gold-silver project confirmed numerous vein systems of mineralisation dominant in important copper-bearing ore chalcocite across significant strike lengths.

The program notably observed massive chalcocite veining alongside three other chalcocite veins and cemented copper-rich breccia at the Cu-Tar area, now sampled along strike until disappearing under cover.

And White Cliff Minerals believes the discovery of high-grade sedimentary-hosted copper and replacement mineralisation seen at the HALO area has greatly expanded the project’s prospectivity and raw tonnage potential.

There was also native copper seen within vesicular basalt flow tops at Kilauea, two semi-massive chalcocite-bornite veins at DON, outcropping, semi-massive, vein-hosted chalcocite-bornite at PAT, and field evidence of copper-bearing hydrothermal fluids at CALMAL.

Maiden fieldwork over its relatively nearby Great Bear Lake project in the Northwest Territories likewise validated the allure for large mineralised systems, and White Cliff expects a first tranche of assays to come in next month.

White Cliff Managing Director Troy Whittaker said the outcropping copper through the area was visually stunning and had exceeded expectations, and detailed two main objectives for the maiden field programs.

“Firstly, to confirm decades-old historical state-survey results from multiple project locations and extend the observable strike of each and, in parallel, undertaking airborne geophysics to further refine these targets,” he said.

“Second is prioritise and prepare project areas for drilling. At Halo, multiple mineralised vertical structures have been identified and now constitute priority targets.

“This deep-seated plumbing acts as conduits for copper-rich hydrothermal fluids that have deposited what appears to be significant quantities of copper into the surrounding reactive sandstones.”

Whittaker said that while previously unfound, its field observation provided the first direct evidence of extensive high-grade sedimentary hosted red-bed copper on White Cliff territory.

He added the sampling program was growing confidence in the find by the day, and the team expected an airborne survey over Great Bear to substantially raise the company’s understanding of local and regional mineralising structures.

“Integrating this geophysical layer with assay results will eventually allow for a maiden drilling campaign by the company which is scheduled to kick off in the coming months,” he said.

“The same aerial survey is now underway at Rae, and expected to complete this week.”

Exploration spending in the Nunavut territory has swung upwards this year, a fact the Perth-based explorer believes has amplified a first-mover advantage as it prepares for maiden drilling.
