White Cliff Minerals (ASX:WCN) reports step-out drilling results that extend the ‘ultra high-grade’ Danvers 3 copper zone to more than 220m of strike at its Rae Copper Project in Canada.
Hole DAN26036 returned 23m @ 6.18% copper (Cu) and 13 grams per tonne silver (Ag) from 161m, including 3.9m @ 16.45% Cu and 31g/t Ag from 175.4m, with a peak assay of 23.5% Cu.
The result is the ‘highest copper grade’ returned from the Danvers prospect to date.
The hole was drilled 105m west of discovery hole DAN26012, extending the ‘high-grade’ chalcocite breccia trend more than 220m along strike.
A further 248m of strike remains untested to the next drillhole southwest, with mineralisation remaining open towards surface and depth.
Managing Director Troy Whittaker says DAN26036 delivered the type of result the company wants from step-out drilling.
“More than 220m from DAN26012, it has delivered 23m at 6.18% copper, including 3.90m at 16.45% copper and a new Danvers record assay of 23.5% copper — assays that demonstrate thick and high-grade continuity of the copper mineralisation,” Whittaker notes.
The company says oriented diamond core, assay results, and magnetic data are converging on a consistent control for high‑grade chalcocite mineralisation. The strongest mineralisation are concentrated within permeable breccias along the flanks of the Teshierpi Fault Zone.
A fast‑tracked Danvers 1 infill hole intersected 42.19m of bornite‑chalcocite dominant vein and breccia‑hosted mineralisation between existing drillholes, with assays pending.
At Danvers 4, a hole intersected 31.43m of chalcocite and bornite mineralisation 365m northwest of Danvers 1.
White Cliff Minerals plans three additional diamond holes through the Danvers 1 core breccia zone to test down‑dip and plunge extensions.
This program will be followed by systematic testing of continuity between wide‑spaced drillholes that have returned copper mineralisation.
