White Cliff Minerals (ASX:WCN) diamond drilling continues to expand the Danvers Copper System

White Cliff Minerals has reported further drilling results and geological observations from the Danvers prospect at its Rae Copper Project.

The announcement includes additional reverse circulation assay results from Danvers 1 together with observations from the first diamond drillhole into the Teshierpi Fault Zone.

The company states that the drilling has expanded the known mineralised footprint and provided additional geological information.

Data gained from the first hole has allowed the company to further update its geological model, with holes now being drilled using a vector towards further high grade prospective areas.

Highlights

The announcement states that the maiden diamond drillhole, DAN26025, was strategically positioned to test geological and structural controls proximal to DAN26012, which previously returned 19.81m @ 6.64% Cu.

The company states that more than 73m of visual chalcocite and chalcopyrite sulphide mineralisation was intersected, expanding the known mineralised footprint by approximately 50m to the northeast.

The company also reports that ongoing drilling continues to confirm chalcocite and bornite as the dominant copper sulphides within the mineralised zones intersected across the project.

According to the announcement, drill core observations identified a prospective breccia horizon hosting chalcocite calcite cement within crackle and mosaic textured breccias along the shoulder of the Teshierpi Fault Zone's main chaotic breccia.

The company states that this horizon provides a clear structural and permeability controlled target for high grade copper mineralisation, with copper sulphides precipitated directly within open space breccia textures adjacent to the main fault zone.

The reverse circulation drilling program also returned additional assay results from Danvers 1, with hole DAN26020 returning 19.81m @ 0.72% Cu from 111.25m, including 1.53m @ 2.39% Cu and 3.05m @ 1.11% Cu.

The company states that the result extends the Danvers 1 footprint by 218m to the southwest, with the Danvers 1 mineralised footprint now spanning a strike of 1037m.

Additional reported results include 10.67m @ 0.28% Cu from DAN26017, 3.05m @ 0.28% Cu from DAN26018 and 1.52m @ 0.23% Cu from DAN26019.

The announcement further states that the 2026 RC drilling program has defined new mineralisation within the Teshierpi Fault Zone at a kilometre scale.

High grade intervals in DAN26008, DAN26012 and DAN26015 define a 1.37km strike length interval where drillhole spacing exceeds 300m.

Current drilling efforts aim to define the orientation and style of mineralisation using oriented drill core, with the company stating that this information will inform step out drillholes.

White Cliff Managing Director Troy Whittaker said,

"Importantly, our first diamond drillhole into the Teshierpi Fault Zone has intersected more than 70 metres of copper sulphide mineralisation and has materially improved our understanding of the architecture of the system. The hole has isolated a key mineralised horizon within the fault and breccia package, giving us a much clearer target for follow up drilling along strike and at depth."

The company states that drilling to complete the Phase 1 regional spaced campaign across the 12,000m strike remains on target for completion during July.

Diamond drilling is underway and is designed to infill the Phase 1 campaign, with multiple assay results remaining pending, including those from drillholes DAN26022 and DAN26024, together with assays from the current diamond drilling program.

The company also states that drilling will continue to target high grade copper zones, with the northeast extent of the fault zone still largely untested.
