Key Highlights

  • Diamond hole DAN26058 logged visual copper sulphides to 521 metres, the deepest hole at Danvers to date.
  • Hole DAN26050 returned 63 metres at 0.39 percent copper from 21 metres, identifying a new shallow zone.
  • Two holes within an untested 580 metre gap between Danvers 2 and Danvers 3 logged extensive visual copper sulphides.
  • Several results are visual estimates rather than laboratory assays, and assay confirmation is still required.

White Cliff Minerals Limited (ASX:WCN) has reported deeper drilling results from Danvers 1 and visual observations from infill drilling at its Rae Copper Project, according to an announcement dated 12 November 2026. The company says the deep diamond hole extended copper mineralisation to depth and identified a new shallow zone, while infill holes support continuity between the Danvers 2 and Danvers 3 prospects. The update is largely built on visual logging, so it provides an early picture of the system rather than a grade-based assessment.

Deep drilling at Danvers 1

Hole DAN26058 logged a cumulative 386 metres of visual copper sulphides, starting from just 13 metres downhole and including several zones of chalcocite and bornite cemented breccias. The hole logged copper sulphides to 521 metres downhole, or about 410 metres vertical depth. The company says the hole provides geological, structural and density data, along with samples for future metallurgical and comminution testing.

The company argues the result enhances the potential for down-plunge continuation of the shallow, chalcocite-rich breccias. Visual estimates of mineral abundance, however, are not assays, and the company itself cautions that they should not be treated as grade. Laboratory results will be needed before any judgements can be made about tenor.

A new shallow zone and deeper mineralisation

Hole DAN26050 returned 63 metres at 0.39 percent copper from 21 metres, adjacent to the main Danvers 1 breccia. The company says this expands the known mineralised footprint beyond the main breccia system. Separately, hole DAN26048 returned 25.14 metres at 0.69 percent copper from 203.36 metres, which sits below historical drilling and extends to about 180 metres vertical depth.

Continuity between Danvers 2 and Danvers 3

Two diamond holes drilled into a previously untested 580 metre gap between Danvers 2 and Danvers 3 logged 86.89 metres and 155.33 metres of visual copper sulphides. The company says these results strengthen its emerging geological interpretation of a more continuous mineralised system between the two prospects. Continuity, however, has yet to be demonstrated by assays across that gap.

Final Word

The Danvers results indicate that copper sulphides extend deeper and wider than earlier drilling had shown, which broadens the target area at the Rae Copper Project. The assay results, the metallurgical and comminution work and the continuity of mineralisation between prospects will determine how much of the visual evidence translates into economic grade. Until those results are reported, the project remains at an exploration stage.
