White Cliff Minerals (ASX:WCN) has reported its first diamond drill hole at the Danvers Copper Project returned 50.9m @ 2.81% copper (Cu) and 7.66 grams per tonne silver (Ag) from 39.7m depth.
Hole DAN26026 included multiple ‘high-grade’ intervals, with 4.3m @ 10.93% Cu and 15.6g/t Ag from 45m — the latest intercept at Danvers to exceed 10% Cu.
Other zones included 6.8m @ 3.93% Cu and 11.6g/t Ag from 55.5m, and 4.75m @ 7.12% Cu and 28.6g/t Ag from 64.25m.
Managing Director Troy Whittaker says the result demonstrates the ‘tenor and scale potential’ of the mineralised system.
“Our first diamond hole at Danvers has delivered an exceptionally broad, near-surface, high-grade copper result, returning more than 50m at 2.81% Cu, including an exceptional 4.3m at 10.93% Cu — the latest intercept at Danvers to again exceed 10% copper — further demonstrating the exceptional tenor and scale potential of the mineralised system,” Whittaker adds.
Executive Director for Technical Eric Sondergaard says the oriented diamond core has provided crucial structural information for future targeting.
“The key objective of this first diamond hole was to obtain the geological and structural information needed to refine the model and systematically target extensions to the mineralized system. DAN26026 has achieved exactly that,” Sondergaard notes.
The hole was collared more than 50m southwest of previous hole DAN25001 and validates the geological model while confirming broad ‘high-grade’ copper mineralisation previously intersected by reverse circulation drilling.
The mineralisation is hosted within a breccia that is strongly chlorite altered, with copper sulphides present as disseminations, sulphide veinlets, breccia cement, and locally associated with quartz-carbonate veining.
‘High-grade’ intervals are dominated by bornite and chalcocite with lesser chalcopyrite.
White Cliff Minerals has 21 additional diamond assays pending, including from step-out holes testing ‘high-grade’ zones previously intersected in holes DAN26012 and DAN26015.
The Rae Copper Project comprises 93 mineral claims and one mineral lease covering 1,228km2 in Nunavut, Canada. The project includes the Danvers deposit, which has a historic resource estimate of 4.16 million tons @ 2.96% Cu.
