White Cliff Minerals Limited (ASX: WCN) has announced the final batch of assay results from rock chip samples taken during its 2024 maiden field programme at the company’s Rae Copper Project in Nunavut, Canada. These results indicate widespread outcropping, high-grade copper throughout the licence areas and appear to have significant lateral extent.
“The Rae Project continues to reinforce its potential with another set of very encouraging results. Like Vision, to the north-west, these two newly confirmed areas at Rocket and Thor have delivered extraordinary & extensive copper grades across what is now a very large overall area. More than half of the samples taken from these projects returned results of more than 20% copper. I’m pleased to report that the Aerial Geophysics data from the next generation MobileMT survey continues to progress through the process stage gates – analysis, interpretation, audit, and validation, and remains on target to be released in the upcoming weeks.” Said Troy Whittaker, MD.
Final assay results confirm multiple large-scale, high-grade copper occurrences at both Rocket and Thor project areas. At Rocket, host to the historic Cu-TAR occurrence, three parallel chalcocite dominant vein systems were sampled along a strike length exceeding 380m within an area of ±400m x 200m, returning:
- § 54.12% Cu and 14g/t Ag (F005950)
- § 53.82% Cu and 27g/t Ag (F005949)
- § 53.47% Cu and 26g/t Ag (F005935)
- § 53.24% Cu and 13g/t Ag (F005944)
- § 51.59% Cu and 20g/t Ag (F005942)
- § 48.56% Cu and 60g/t Ag (F005938)
- § 37.7% Cu and 17g/t Ag (F005933)
- § 37.3% Cu and 15g/t Ag (F005937)
Within the broader Rocket project area, the PC140 vein system, around 5km north-west of Cu-Tar, along a major structural trend returned copper grades of 13.45% Cu (F005955), 12.85% Cu (F005954), and 7.15% Cu (F005957) from a limited sampling campaign over >200m.
At the Thor System, host to the historic HALO occurrence a total strike length of over >800m of copper mineralisation was identified and sampled, with high-grade results from 16 rock chip samples over >400m demonstrating continuity in the mineralised structural trend. Results included:
- § 54.02% Cu and 34g/t Ag (F005921)
- § 25.7% Cu and 22g/t Ag (F005922)
- § 24.4% Cu and 12g/t Ag (F005927)
- § 24.1% Cu and 4g/t Ag (F005931)
- § 23.8% Cu and 3g/t Ag (F005932)
- § 21.2% Cu and 9g/t Ag (F005928)
“Marking the first application of modern, project scale geophysics at Rae, the survey will provide a detailed look into the subsurface. Utilizing the magnetic data will allow for definition of prospective structures and sub basins, with the conductivity response isolating hot spots within targets such as Hulk, less than 2km west of the Kaizen copper discovery. As this represents the final round of assays, I would like to congratulate the geological team who have safely, on budget and to schedule, executed this maiden campaign in the Canadian North which has delivered exceptional results – including assays that may in fact represent the highest-grade copper and silver rock chip results in recent history.” Added Troy.
