Large Scale Copper Discovery Confirmed

White Cliff Minerals Limited (“the Company”) is delighted to announce the first batch of assay results from rock chip samples taken during the 2024 maiden field program at the Rae Copper Project in Nunavut, Canada (“Rae” or “the Project”). Results confirm outcropping and high-grade copper and precious metals hosted in extensive massive chalcocite vein systems of significant lateral extent.

• Copper and silver assays received for three of the five exploration districts at Rae
• Representative rock samples from extensive outcropping massive chalcocite veins returned exceptional copper-silver ± gold and confirm what is now believed to be the first major discovery on the Company licence area
• The Vision District, a ±10km long NE/SW structural corridor which includes the Don and Pat project areas. Occurring within a “sub parallel, dilutional jog” that provided the necessary depositional environment for copper and precious metal accumulation. It is also possible, although yet to be proven, that these two project areas are contiguous, meaning the two localised ±km long zones of massive chalcocite may be one body up to ±5km in length. Recently flown geophysical surveys will confirm this either way
• At Don several parallel outcropping massive chalcocite veins running roughly NE/SW have been identified over an area of more than 2km2 and returned results of:

• At Pat, ±4.4km along strike from DON & around 600m of visual outcrop, returned assays of:

• The Company’s primary focus, Hulk, a large scale sedimentary hosted copper target, is a 16x4km magnetic anomaly within the reactive basal sequence of the Rae Group sedimentary basin which has been identified coincident with extensive surface staining of malachite with one sample, F005987, returning 1.65% Cu. The identification of copper in this area provides geological proof for the first time that copper rich hydrothermal fluids have in fact permeated the sedimentary basin. This geological environment is considered a high priority for drilling
• Remaining assay results (41 samples) from the Thor and Rocket Districts are expected are over the coming weeks
• The Project saw the completion of one of Canada’s largest aerial geophysical survey’s covering 2,500 line-km of MobileMT geophysics, marking the first license scale survey completed in history at the Project with these results due during the December quarter

White Cliff’s Great Bear Lake Project potentially holds the mantle of the highest ever recorded representative Silver rock sample assay result of 7.54% Ag and now, the Rae Project can lay claim to the highest ever recorded representative Copper rock sample assay.

The results also demonstrate the deep plumbing, copper rich fluids & fertile nature of the host rocks of basal part of the Rae sedimentary sequence and provide longer-term opportunities for not just bulk tonne sedimentary hosted copper but potential for direct shipping of a high-grade copper concentrate using a mine and ship approach from these newly identified chalcocite veins.

In the next months the company expects to receive the MobileMT geophysical results which will sharpen the resolution of the previous groundwork, confirming drilling targets for the upcoming campaign, which will include the priority - Hulk, a very large, green at surface, 16km by 4km target within the reactive subsurface basal units (siltstones and mudstones) of the Rae Sedimentary Basin, this basin has been intersected by similar mineralising regional structures proven to be copper conduits including those seen at Vision.

These two projects are proving to be world class exploration opportunities. Rae and Great Bear are located in a tier one mining and investment jurisdiction, on the mainland, with significant infrastructure already in place.”

Troy Whittaker - Managing Director

“The team at WCN have built a solid foundation of high-quality projects through old school geological hard work. Results of this nature are rare and to have them repeated over some distance is very encouraging. I look forward to the upcoming work as we prepare for drilling.”
