White Cliff Minerals (ASX:WCN) has reported assay results and visual observations from drilling at its Rae Copper Project in Canada, with drillhole DAN26058 logging copper sulphides to 521 metres downhole at Danvers 1, making it the deepest hole at Danvers to date at 410 metres vertical depth.

Key Points

  • DAN26058 logged a cumulative 386 metres of visual copper sulphides commencing at 13 metres downhole, extending to 521 metres downhole
  • DAN26050 returned 63 metres at 0.39% copper from 21 metres downhole, identifying a new shallow mineralised zone adjacent to the main Danvers 1 breccia
  • DAN26048 returned 25.14 metres at 0.69% copper from 203.36 metres downhole, marking a 180 metres vertical depth intersection
  • Infill drillholes DAN26054 and DAN26056 logged 86.89 metres and 155.33 metres of visual copper sulphides respectively within a previously untested 580-metre gap between Danvers 2 and Danvers 3

Deep Drilling Results at Danvers 1

Drillhole DAN26058 was drilled down-dip of the Danvers 1 breccia body and logged visual copper sulphides commencing at just 13 metres downhole, including multiple zones of chalcocite and bornite cemented breccias. Semi-massive bornite mineralisation was observed at 456 metres downhole, confirming mineralisation below previous drilling efforts. The hole was designed to test the depth potential of Danvers 1 while providing geological, structural and density data, together with samples for future metallurgical and comminution test work. Assays from the deep hole are expected within six to eight weeks, according to the filing.

New Shallow Zone and Additional Assay Results at Danvers 1

Drillholes DAN26049 and DAN26050 were drilled on the same section and returned a new zone of mineralisation parallel to the main Danvers 1 deposit. DAN26050 intersected 63 metres at 0.39% copper from 21 metres downhole, identifying a new mineralised zone adjacent to the main Danvers 1 breccia and expanding the known mineralised footprint. DAN26048 returned 25.14 metres at 0.69% copper from 203.36 metres downhole, extending mineralisation to approximately 180 metres vertical depth below surface. Drillholes DAN26048, DAN26049 and DAN26050 were designed to test below historic drilling and address specific pinch points in the geological model.

Infill Drilling Between Danvers 2 and Danvers 3

Two diamond drillholes, DAN26054 and DAN26056, were planned to test within a 586-metre gap between spring drillholes DAN26005 and DAN26008 at the Danvers 2 and 3 discovery area. DAN26054, located 163 metres southwest of DAN26052, logged 86.89 metres of visual copper sulphides, while DAN26056, located a further 184 metres southwest, logged 155.33 metres of visual copper sulphides. Both holes intersected copper sulphides along the main Teshierpi Fault Zone. The company stated that current drilling is expected to provide a critical foundation for geological modelling, supporting the definition of an Exploration Target and progressing the project towards a Maiden Mineral Resource Estimate.
