White Cliff Minerals Extends Danvers 3 Copper Zone with Record 23.5% Assay

Danvers 3 Step-Out Drilling Sets New High-Grade Benchmark

White Cliff Minerals (ASX:WCN) has delivered a standout result from its Rae Copper Project, with drillhole DAN26036 returning 23 metres at 6.18% copper and 13g/t silver, including an eye-catching 3.90 metres at 16.45% copper and a peak assay of 23.5% copper, the highest grade recorded at Danvers to date. This exceptional step-out hole, drilled 105 metres west of the initial discovery, extends the ultra high-grade chalcocite breccia zone to more than 220 metres along strike, with mineralisation still open both at depth and towards surface.

The mineralised zone's expansion is significant given the previous Danvers 3 intercepts, confirming continuity and suggesting a robust copper system. The 248-metre untested gap to the next drillhole southwest offers a clear runway for further discovery and resource growth. This latest result builds on the company’s ongoing strategy to aggressively delineate and expand the Rae copper footprint.

Structural Controls and Magnetic Data Sharpen Targeting

White Cliff’s geological team is piecing together why such high copper grades are concentrated in Danvers 3. The mineralisation is tightly associated with permeable crackle and mosaic breccias along the flanks of the Teshierpi Fault Zone, a major regional structure. Oriented diamond core and magnetic data converge on this structural control, providing a reliable vector for targeting future drilling.

This structural insight is a game-changer for the Rae Project, enabling the company to focus on the more permeable margins of the fault zone where copper-bearing fluids have preferentially deposited high-grade chalcocite mineralisation. The integration of magnetic gradients with geological observations enhances the precision of exploration efforts.

Danvers 1 Infill Drilling Confirms System Continuity

Complementing the Danvers 3 expansion, infill diamond hole DAN26047 at Danvers 1 intersected 42.19 metres of bornite-chalcocite dominant vein and breccia-hosted copper sulphides between previous drillholes. While assays are pending, the visual confirmation of extensive copper sulphides strongly supports the continuity of the high-grade system in this core breccia zone.

Further diamond drilling is planned to test down-dip and plunge extensions at Danvers 1, aimed at refining the geological model and enhancing confidence in the resource base.

Expanding the Copper System Footprint at Danvers 4 and Beyond

Drilling at Danvers 4 has also intersected significant copper mineralisation, including 31.43 metres of chalcocite and bornite sulphides, located 365 metres northwest of Danvers 1. These results hint at a possible structural connection between Danvers 4 and Danvers 1, potentially broadening the scale of the mineralised system.

White Cliff plans to push further step-out drilling at Danvers 2 and 3 to test large strike gaps of over 500 metres, aiming to materially expand the known copper footprint. The company’s aggressive drilling schedule reflects a commitment to unlocking the Rae Project’s district-scale potential.

Rae Copper Project: A District-Scale Copper Opportunity

Beyond the Danvers discoveries, the Rae Copper Project hosts sediment-hosted copper mineralisation with a footprint now extended to approximately 6.3 square kilometres. Historical and recent drilling have confirmed copper sulphides along a significant regional redox boundary, drawing parallels to prolific copper belts globally.

Metallurgical test work supports the economic potential, with recoveries exceeding 95% for copper and over 93% for silver using conventional flotation methods. The combination of high-grade intercepts, structural targeting, and metallurgical amenability positions the Rae Project as a compelling copper exploration story in a top-tier jurisdiction.

Troy Whittaker, Managing Director, encapsulated the significance: "DAN26036 is exactly the type of result we want from step-out drilling... The high-grade zone remains open, with another 248 metres still untested towards the next drillhole in the southwest. We are now understanding why the high grades occur, linked to permeable breccia along the Teshierpi Fault Zone. Multiple high-grade centres are emerging within a much larger copper system as we continue to drill aggressively."
