White Cliff Minerals (ASX:WCN) has reported assays confirming ‘high-grade’ copper-silver mineralisation extends to more than 280m vertical depth at its Danvers Copper Project in Nunavut, Canada.
Scissor hole DAN26030 returned multiple copper intervals, including 17.08m @ 1.89% copper (Cu) and 7.51 grams per tonne silver (Ag) from 166.9m. This hole incorporates 2.39m @ 5.05% Cu and 11.91g/t Ag, and a ‘higher-grade’ zone of 5.45m @ 4.36% Cu and 23.8g/t Ag.
The hole ended in mineralisation, with the final 9.64m returning 1.08% Cu and 8.62g/t Ag, leaving the system open at depth.
Step-out drilling 449m northeast confirmed strike continuity, with DAN26034 returning 1.42m @ 1.33% Cu from 225.29m and 1.5m @ 3.68% Cu from 256.5m.
Managing Director Troy Whittaker says the results ‘strengthen’ the exploration model at Danvers 3 and provide vectors for follow-up diamond drilling targeting thicker and ‘higher-grade’ components of the mineralised system.
“Phase 1 delineated massive lateral extent and continuity of mineralisation across Danvers. DAN26030, the latest assay, is particularly important, extending the Danvers 3 system to more than 280m vertical depth while providing new geological information on its internal metal zonation,” Whittaker notes.
Phase one drilling has confirmed copper mineralisation across 4,933m along the Teshierpi Fault Zone and 3,152m at Danvers 1 and its strike extensions.
Including holes pending assay, sulphides have been observed across 6,499m and 4,755m respectively.
The mineralised footprint surrounding DAN26012 now extends approximately 866m laterally and to more than 280m vertical depth, comparable to the broader envelope surrounding the historic Danvers 1 estimate.
Lead-rich metal zonation adjacent to and partially overlapping the deeper copper-silver mineralisation provides an additional vector toward ‘higher-grade’ components.
The next phase of drilling will prioritise stepping out from ‘high-grade’ copper zones at Danvers 3, testing strike and depth extensions at Danvers 1, and testing extensions to Danvers 2 and Danvers 4.
WCN holds 93 mineral claims and one lease covering 1,228km2 in the Kitikmeot region. The project contains a historic resource estimate of about 3.77 million tonnes at 2.96% copper, though it is not JORC compliant.
White Cliff Minerals is a Perth-based explorer with a portfolio spanning gold, copper, lithium, rare earth elements, and uranium across Australia and Canada.
