White Cliff Minerals (ASX:WCN) expands Danvers 1 copper trend to 4.75km

White Cliff Minerals has reported further assay results from the Danvers copper system at its Rae Copper Project, where drilling has intersected copper mineralisation over 4.75km of the interpreted Teshierpi structural corridor, compared with approximately 820m of strike tested around Danvers 1 during the 2025 program.

Highlights

The drilling program has extended northeast of the original Danvers 1 area through regional holes positioned along the interpreted Teshierpi structural corridor.

DAN26027 was collared 225m northeast of DAN25020, which previously returned 64m @ 0.89% Cu, including 9.14m @ 2.65% Cu.

DAN26031 was collared a further 1.1km northeast and returned its reported interval from 166.5m, while DAN26035 was collared more than 2.5km northeast of the Danvers 1 core and DAN26033 returned 34m @ 0.18% Cu from 136m of disseminated copper mineralisation.

Drilling northeast of Danvers 1 has so far been completed on spacing between 300m and 670m, with further infill drilling required to establish the continuity, geometry and grade distribution of individual mineralised zones, as the current drill spacing is regional in nature.

White Cliff Managing Director Troy Whittaker said,

“We are accelerating infill and depth drilling to test the substantial gaps between existing holes, target broader breccia development and begin converting this 4.75km trend into a more continuous geological and mineralisation model.”

Danvers 1 sits on a southeastern splay of the regional Teshierpi Fault and occupies a distinctive magnetic low that can be traced northeast.

The relationship between structure and magnetic response formed part of the targeting criteria for the regional exploration program and is increasingly being used to predict where mineralised structures may broaden or develop stronger brecciation.

Mineralisation appears disseminated in the basalts, infills vesicles in flow tops and forms cross cutting quartz carbonate copper sulphide veins dominated by chalcocite, bornite and chalcopyrite.

Northeast of Danvers 1, where the host structure becomes tighter and is represented by a narrower magnetic low, mineralisation is more typically hosted in planar quartz carbonate veins containing chalcocite and bornite.

Where the magnetic signature appears wider, more developed fault breccia is typically discovered, with the breccia hosting mineralisation at Danvers 1 and the highest grades occurring at the edges in crackle and mosaic type breccias at Danvers 3.

The magnetic signature is consistent between the reported drill holes, supporting continuity of the host structure, although further drilling is required to establish mineralised continuity.

Assays remain pending for DAN26041, which was collared 212m northeast of DAN26027 along the mineralised trend, where more than 40m of copper sulphide bearing core was observed.

The company stated that visual estimates of mineral abundance should not be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest.

Previously reported metallurgical test work at Danvers returned more than 95% Cu and more than 93% Ag recoveries through conventional processing.

Current drilling is focused on establishing geometry and continuity ahead of an evaluation of a JORC Exploration Target and future resource definition.

Diamond drilling is now infilling the widely spaced Phase 1 regional holes, with targets being refined as oriented core improves the company’s understanding of structural controls on mineralisation.

The next phase will prioritise increasing drill density at Danvers 1 and along the northeastern trend, testing strike and depth extensions, expanding known mineralisation at Danvers 2, Danvers 3 and Danvers 4, and assessing analogous structural and geophysical targets across the wider Teshierpi Fault Zone.
