White Cliff Minerals Hits Copper on Untested 2.8km Structure Beside Danvers 1
Key Takeaways
- DAN26053, the first hole into an untested parallel structure, intersected 28.52m of visual copper sulphides from just 16m downhole, opening a 2.8km target less than 200m from Danvers 1.
- All three north-east infill holes hit copper sulphides across 1,397m of lateral strike, extending the mineralised footprint over 2.3km north-east of core Danvers 1.
- Every sulphide figure is a visual estimate, not an assay, and laboratory results are due in 6-8 weeks as the next value catalyst.
- An earlier assay of 76.5m at 2.01% Cu from DAN26047 shows the grade this system has delivered, though it is separate from the visual estimates.
- A 72km airborne survey and till sampling at Thor and Rocket are underway, with drilling feeding a maiden Exploration Target and Mineral Resource Estimate for Danvers 1.
New copper discovery on untested 2.8km parallel structure at Danvers 1
White Cliff Minerals (ASX: WCN; OTCQB: WCMLF) has reported a new copper discovery at Danvers 1 in its Rae Copper Project. Hole DAN26053, the first hole into an untested parallel structure, intersected copper sulphides from as shallow as 16m downhole.
The structure is mapped for more than 2.8km and sits less than 200m east of the Danvers 1 trend. Copper sulphides were also intersected in every north-east infill hole, and the mineralised footprint now extends over 2.3km north-east of the core Danvers 1 mineralisation.
One caution applies throughout. All sulphide figures in this announcement are visual estimates logged from drill core, not laboratory assays, which are expected in 6-8 weeks.
For investors, the news points to a new target beside an existing system. Several further parallel magnetic features remain untested.
What DAN26053 found
The hole was collared on one of several parallel magnetic lows, a linear feature that represents a structure through the basalts. Until this hole, it had not been drilled.
- 28.52m of copper sulphides were observed in multiple zones of chalcocite and chalcopyrite-bearing veins and breccias (visual estimate).
- The structure joins the main Danvers 1 NE trend approximately 480m north-east of the hole.
- It continues south-west for another 2.3km, for a total strike length of 2.78km.
Those figures are downhole lengths, not true widths, and they say nothing about grade. The company says the long strike length offers scope for step-out drilling in the future.
Troy Whittaker, Managing Director
“Our first hole into this previously untested parallel structure has intersected copper sulphides from just 16 m downhole, opening a new exploration opportunity immediately beside Danvers 1. With approximately 2.8 km of mapped structure to follow up, this discovery gives us a substantial new target for expanding the Danvers copper system…”

Copper sulphides in every north-east infill hole
Three further holes were drilled to infill widely spaced (more than 650m) Phase 1 drilling. Together they covered 1397m of lateral strike, and each intersected copper sulphides.
| Hole | Visual copper sulphides | Key observation |
|---|---|---|
| DAN26051 | 43.68m | Danvers-typical chalcocite-bornite breccia observed between 160-170.38m |
| DAN26055 | 165.67m | Chalcocite-bornite-chalcopyrite logged in veins, veinlets, breccia cements and blebs |
| DAN26057 | 94.50m | Disseminated blebs of copper sulphides, drilled within a more than 650m gap between DAN26031 and DAN26033 |
The company says the results strengthen confidence in continuity and continue to refine its geological model. That supports the next phase of resource definition, advancing toward a maiden Exploration Target and MRE (Mineral Resource Estimate) for Danvers 1.
Separately, a result released on 6 October 2026 reported 76.5m @ 2.01% Cu from DAN26047. That was an assay result, and it is distinct from the visual estimates above.
How visual estimates work, and why assays matter
A visual estimate is a geologist’s judgement of how much sulphide mineral is visible in drill core. It is useful for tracking where mineralisation sits, but it is not a measurement of how much copper the rock contains.
Chalcocite, bornite and chalcopyrite are all copper sulphides, meaning minerals that combine copper with sulphur. Seeing them confirms copper is present, not how much.
The company states that visual estimates should never be treated as a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. That is why this announcement carries a caution.
Assays are expected in 6-8 weeks. For you as an investor, they are the next value catalyst, because they will show whether these intervals carry meaningful grade.

District-scale exploration and next steps
Alongside the drilling, the company has several activities underway at Rae:
- Sander Geophysics is conducting an airborne magnetic-gravity-radiometric survey across 72km of the Rae Group–Husky Creek Formation contact, extending to the Thor and Rocket targets.
- Till sampling is set to commence across Thor and Rocket, aiming to identify near-surface “walk-up” targets with the same geophysical signature as Danvers.
- Diamond drilling continues on parallel structures, the Danvers 1 NE trend and the Danvers 2/3 areas.
- Current drilling is expected to provide a foundation for geological modelling, supporting the definition of an Exploration Target and progress toward a Maiden Mineral Resource Estimate.
The geophysical signature associated with mineralisation at Danvers has now been isolated and validated within the geological model. The company says this gives a geological basis to expand the regional footprint at Rae.
That geophysical signature, a distinctive magnetic response tied to copper mineralisation, was first recognised at Danvers and now underpins how the company ranks parallel features and regional targets across Rae.
For context, the company’s maiden drilling campaign at Danvers included 175m @ 2.5% Cu & 8.66g/t Ag.
The near-term picture is simple. Assays from this round of drilling are pending, and the model-building pathway toward an Exploration Target and maiden Mineral Resource Estimate continues.
