White Cliff Minerals Confirms High-Grade Copper Beyond 280m at Danvers

White Cliff Minerals Confirms High-Grade Copper to Beyond 280 Metres at Danvers

White Cliff Minerals high-grade copper results at Danvers Rae Copper Project Nunavut Canada have drawn considerable attention following the company's latest drilling announcement. White Cliff Minerals (ASX: WCN; OTCQB: WCMLF) has reported results confirming high-grade copper-silver mineralisation extending to greater than 280 metres vertical depth at the Danvers 3 system. The results are anchored by scissor hole DAN26030 and support a geological system now spanning more than 11.2 kilometres of observed copper mineralisation at regional scale, with over 8 kilometres confirmed by assay.

The update follows completion of the company's Phase 1 drilling programme. Management has indicated a shift from broad regional exploration toward more targeted depth and strike testing at priority zones within the project.

Phase 1 by the Numbers: A Regional Copper System Takes Shape

Phase 1 drilling comprised 44 drillholes (24 reverse circulation and 20 diamond), totalling 10,581 metres across 11.8 kilometres of linear strike. Copper sulphide mineralisation has been observed across multiple structural zones.

Thirteen holes from the Phase 1 programme remain pending assay, according to the company, indicating the confirmed footprint may extend further as results are released.

DAN26030: The Scissor Hole Extending the Depth Profile

DAN26030 was drilled as a scissor hole to the previously reported DAN26015, which returned 79.24m at 1.59% Cu from 67.06m. A scissor hole is a drillhole positioned to intersect the same mineralised target as an earlier hole but from a different angle, allowing geologists to confirm the true extent of mineralisation. The hole was designed to test whether the Danvers 3 system carried genuine vertical continuity.

The hole returned multiple high-grade copper intervals, with mineralisation remaining open downhole:

Within the broader 46.1m interval from 334.9m, sub-intervals include 5.79m at 1.08% Cu and 5.72g/t Ag from 345.98m, 2.67m at 2.34% Cu and 6.58g/t Ag from 189.93m, and 25.95m at 0.76% Cu and 5.34g/t Ag from 355.05m.

The final 9.64 metres of the hole returned 1.08% Cu and 8.62g/t Ag, with the hole ending in mineralisation. Consequently, copper has now been confirmed from near surface to more than 280 metres vertical depth at Danvers 3.

"DAN26030 is particularly important, extending the Danvers 3 system to >280m vertical depth while providing new geological information on its internal metal zonation. These latest results materially strengthen the exploration model at Danvers 3 and provide a strong vector for follow-up diamond drilling targeting the thicker and higher-grade components of the mineralised system at depth and along strike," said Troy Whittaker, Managing Director of White Cliff Minerals.

Metal Zonation Provides a New Targeting Vector

The announcement highlights the identification of pronounced lead (Pb) enrichment adjacent to and partially overlapping the deeper copper-silver mineralisation in DAN26030. In copper deposit geology, metal zonation refers to the way different metals concentrate in predictable spatial patterns within a mineralised system, and explorationists can use this information to help direct drilling toward higher-grade zones.

At Danvers 3, the lead-rich zone occurs near the upper portion of the deeper copper zone and decreases as copper mineralisation continues downhole. According to the company, this spatial relationship suggests the most concentrated copper-silver mineralisation may occur further at depth, below the current drill extent.

Management has stated that this zonation data, together with sulphide assemblage observations and oriented core structural data, will be incorporated into follow-up drill targeting.

What Is Metal Zonation? A Brief Explainer

Metal zonation describes the way different metals distribute themselves within a mineralised system. In copper-dominant systems such as Danvers, metals like lead and zinc commonly concentrate in outer or shallower portions of a system, while copper and silver become more dominant toward the core.

For investors, furthermore, this pattern carries several implications:

1. It indicates the system has a structured geological architecture rather than random distribution.
2. It provides a practical targeting tool for guiding future drilling.
3. It supports confidence in the underlying geological model used to interpret the deposit.

Glossary of key terms:

• Scissor hole: A drillhole positioned to intersect the same target as an earlier hole from a different angle, used to confirm the extent of mineralisation.
• Chalcopyrite: A copper iron sulphide mineral and the most common copper ore mineral in many deposit types.
• Chalcocite: A copper sulphide mineral with high copper content, often associated with higher-grade zones.
• Bornite: A copper iron sulphide mineral commonly associated with higher copper grades.
• Down-hole length: The length of mineralisation measured along the drillhole, which may differ from the true thickness of the mineralised zone.

Strike Continuity Confirmed at Danvers 3

Step-out hole DAN26034, collared 449 metres northeast of DAN26030, returned 1.42m at 1.33% Cu from 225.29m and ended in 1.5m at 3.68% Cu from 256.5m, again remaining open downhole.

According to the company, confirming copper mineralisation at similar depths across this separation indicates the Danvers 3 system extends beyond a localised occurrence. The mineralised footprint surrounding Danvers 3 now extends approximately 866 metres laterally and to beyond 280 metres vertical depth, with the broader Danvers 3 trend spanning approximately 2,252 metres, as reported by the company.

This scale is described in the announcement as comparable to the mineralised envelope surrounding the historic Danvers 1 estimate of 4.16 million tonnes at 2.96% Cu. This is a historic estimate, is not compliant with the JORC Code, and has not been verified by a competent person under current reporting standards.

Danvers 4: Phase 1 Diamond Drilling Complete

Phase 1 diamond drilling at Danvers 4 has been completed, with visual copper sulphides intersected across multiple holes. Assay results remain pending.

DAN26038 returned chalcopyrite and DAN26039 returned chalcocite, a copper sulphide mineral with higher copper content, which the company has flagged as an encouraging observation ahead of assay results.

Phase 2 Drilling Agenda

With Phase 1 complete, the company has indicated it will focus on a more targeted phase of drilling guided by structural and geochemical data from oriented core. Priorities identified in the announcement include:

1. Stepping out from high-grade zones at Danvers 3, testing depth extensions below 280 metres and lateral extensions along the 2,252-metre trend.
2. Strike and depth extensions at Danvers 1, drilling both northeast and southwest of the known mineralised zone.
3. Extensions at Danvers 2 and Danvers 4, both of which have previously returned high-grade copper results, including 15m at 4.8% Cu more than 5km down-strike at Danvers 2.
4. Progressive incorporation of pending assays into drill targeting, particularly around Danvers 1.

Drilling is targeting extensions from near surface to approximately 300 metres depth at Danvers 3, according to the company, with infill work at Danvers 4 to be followed by further expansion drilling.

Investment Considerations: Scale, Grade and Geological Understanding

The White Cliff Minerals high-grade copper results at Danvers Rae Copper Project Nunavut Canada underscore an investment profile resting on three factors highlighted in the announcement: scale, grade, and geological understanding.

Scale: More than 11.2 kilometres of observed copper mineralisation, with over 8 kilometres confirmed by assay, spans multiple structural zones including Danvers 1, 2, 3 and 4, and the Teshierpi Fault Zone. The Hulk sediment-hosted copper target, located on the same licence area, adds further scope, with 2026 drilling extending that system's interpreted footprint to approximately 6.3 square kilometres.

Grade: The historic Danvers 1 estimate of 4.16 million tonnes at 2.96% Cu provides a grade reference point, though this figure remains historic and non-JORC compliant. Reported drilling intercepts, including 90m at 4% Cu, 175m at 2.5% Cu, and the 79.24m at 1.59% Cu from DAN26015, suggest current mineralisation is operating within a broadly comparable grade range.

Geological understanding: The identification of metal zonation at Danvers 3 provides a geochemical vector toward higher-grade portions of the system, according to the company. Combined with oriented core data, this is expected to improve the precision of Phase 2 targeting relative to the regional Phase 1 programme.

Previously announced metallurgical test work returned up to 95.4% Cu recovery and 93.3% Ag recovery through conventional flotation, producing concentrates of approximately 40% Cu, which the company has cited as supporting the processability of the mineralisation style.

Key Factors for Investors to Monitor

What Is the Significance of DAN26030 for the Danvers 3 System?

DAN26030 extended confirmed copper-silver mineralisation to beyond 280 metres vertical depth and identified new metal zonation data, which the company has described as strengthening the geological model and providing a vector for follow-up drilling.

Is the Historic Danvers 1 Estimate a Current JORC-Compliant Resource?

No. The 4.16 million tonnes at 2.96% Cu estimate is historic, dated to 1967 and 1968 drilling, and has not been verified in accordance with the JORC Code 2012. A competent person has not undertaken sufficient work to report it under current standards.

What Comes Next for the Rae Copper Project?

According to the announcement, Phase 2 drilling will prioritise depth and strike extensions at Danvers 3, strike testing at Danvers 1, and further work at Danvers 2 and Danvers 4, with pending assays from 13 Phase 1 holes to be progressively incorporated into targeting.

Key Takeaway: White Cliff Minerals high-grade copper results at Danvers Rae Copper Project Nunavut Canada confirm copper-silver mineralisation to beyond 280 metres vertical depth at Danvers 3, supported by more than 11 kilometres of copper mineralisation defined across the broader Rae Copper Project. With metal zonation data now informing drill targeting and 13 holes still pending assay, investors may wish to monitor upcoming results as Phase 2 drilling progresses.
