White Cliff Minerals Danvers Delivers Best Copper Drill Results Yet

White Cliff Minerals Confirms Expanding High-Grade Copper System at Danvers — Best Drill Results Yet Delivered as Footprint Surpasses 3km

White Cliff Minerals Danvers copper drill results in Nunavut Canada have captured significant attention as the company releases compelling assay and drilling observation results from its ongoing 2026 reverse circulation campaign. The Danvers prospect, part of its Rae Copper Project in Nunavut, Canada, is delivering results that push the confirmed copper mineralised footprint to more than 1.8km in strike length, while visual observations from regional step-out drilling have now traced copper sulphides across approximately 3.1km of the Teshierpi Fault Zone.

The program's standout hole — DAN26008 — has delivered the strongest assay results of the entire 2026 program to date, and a newly discovered bornite-dominant zone along the southeastern fault contact has materially expanded the exploration search space. These developments meaningfully advance the investment case for White Cliff Minerals by delivering new high-grade drill intersections, expanding the mineralised system in both strike and structural complexity, and introducing a new zone outside the fault contact that has been the primary focus of drilling to date.

DAN26008: The Program's Best Hole Yet — and the System Remains Open

Drillhole DAN26008 is located 584m northeast of DAN26005, which had previously returned notable copper intervals above 1% Cu. The step-out distance signals the system's lateral continuity, and the assay results confirm it decisively.

According to the announcement, DAN26008 intersected two thick, high-grade copper zones associated with the major fault system:

Both zones are reported to be associated with the major Teshierpi Fault structure. The hole has tested the system to 130m vertical depth and remains open both at depth and towards surface, meaning future diamond drilling — planned to commence by mid-June — will be targeting areas that have not yet been drilled.

"DAN26008 has returned the strongest assay results from the 2026 program to date, with broad, high-grade copper intersections located within a rapidly developing Greenfields area. Importantly the system remains open at depth and towards surface, while ongoing regional step-out drilling continues to intersect visible copper sulphides along the Teshierpi Fault Zone," said Troy Whittaker, Managing Director.

The grades in DAN26008 are noteworthy even in isolation. A 2.96% Cu core interval sits comfortably in the high-grade range for copper exploration, consistent with the kind of mineralisation quality the historic Danvers resource was built on — a historic non-JORC estimate of 4.16 million tons at 2.96% Cu, made in 1967–68.

Confirmed Mineralised Strike Now Exceeds 1.8km — Visuals Suggest 3.1km

One of the most significant themes running through this announcement is the accelerating growth of the Danvers copper system's footprint. The key metrics investors should be tracking are:

• Assay-confirmed copper mineralised strike: >1.8km
• Visual copper sulphide observations across strike: ~3.1km
• Total Teshierpi Fault Zone strike length across the project: >10km NE/SW

According to the report, every single drillhole targeting the main fault zone in the 2026 program has returned intervals bearing copper sulphides. That is a significant geological statement about the pervasive, well-endowed nature of this structure.

Furthermore, copper sulphide observations across the three most recent holes reinforce this picture:

A New Discovery: The Southeastern Fault Contact Opens an Entirely New Exploration Flank

Perhaps the most strategically significant result in this announcement is from DAN26015, which has intersected a 77.72m zone of bornite-dominant copper sulphides along the southeastern fault contact of the Teshierpi Fault Zone. This represents a genuinely new exploration development.

Up to this point, the vast majority of drilling has been focused on the northwestern fault contact. DAN26015 has now demonstrated that the southeastern contact can also host substantial mineralisation — in this case, with bornite observed at up to 3% abundance in disseminated, vein-hosted, and aggregated form.

The significance of this development lies in the Teshierpi Fault Zone having two major contacts — northwestern and southeastern. If both contacts are mineralised along the 3.1km of strike that has now been drill-tested, the total mineralised volume of the system could be substantially larger than previously understood. The company's Managing Director has explicitly described this development as opening "a new exploration search space within the broader fault zone."

DAN26015 is located approximately 1,400m northeast of DAN26008 and 620m northeast of DAN26012, consequently continuing the systematic northeast step-out progression that is closing the gap toward the known high-grade Danvers 1 area.

Near-Surface Continuity Confirmed by DAN26006

Alongside the deeper step-out results, DAN26006 has returned near-surface mineralisation with practical significance for resource geometry. The hole intersected:

• 18.29m @ 0.56% Cu from 38m (broad zone)
• 6.10m @ 1.16% Cu from 42m (higher-grade core, within the above)

This demonstrates continuity of copper mineralisation close to surface — complementing the deeper intersections previously confirmed in DAN25019 and DAN26004. Near-surface copper mineralisation carries potential significance for future resource estimation and eventual mining scenario planning, as it reduces the depth at which economic mineralisation is encountered.

Understanding Bornite: Why the Copper Mineral Type Matters

What Is Bornite?

Bornite (Cu₅FeS₄) is a copper iron sulphide mineral that is considered one of the most economically valuable copper sulphide minerals. It contains approximately 63% copper by weight, making it a high copper-bearing mineral relative to other common sulphides like chalcopyrite (~34% Cu). In the context of Danvers, the prevalence of bornite — alongside chalcocite — is a meaningful indicator of copper enrichment quality.

Why Does It Matter to Investors?

The copper mineral assemblage at a deposit directly influences processing recoveries and concentrate grades. The 2026 metallurgical testwork completed by Sepro Laboratories on Danvers material (reported separately on 8 April 2026) demonstrated up to 95.4% Cu recovery and 93.3% Ag recovery via conventional flotation, producing concentrates of approximately 40% Cu.

The dominance of bornite and chalcocite — both of which are readily floatable minerals — is central to achieving these high recovery rates. When DAN26015 returns 3% disseminated bornite abundance visually across a 77m interval, it signals the potential for further high-quality mineralisation to be confirmed once laboratory assays are received.

Key Terms Glossary

• Bornite (Bn): High-grade copper sulphide mineral (~63% Cu). Also known as "peacock ore" for its iridescent tarnish.
• Chalcocite (Cc): Secondary copper sulphide (~80% Cu). One of the richest copper minerals.
• Chalcopyrite (Cp): The most common copper mineral (~34% Cu). Lower copper content than bornite or chalcocite.
• RC Drilling: Reverse Circulation drilling. A method where cuttings are returned to surface through the drill rod, allowing fast sampling over large areas.
• Strike Length: The horizontal distance a mineralised zone extends in one direction, typically measured along the dominant structural trend.
• Teshierpi Fault Zone: The major structural corridor running >10km NE/SW through the Rae project, which acts as the primary host and control for copper mineralisation at Danvers.

What's Next: A Busy Drilling Calendar Through Mid-Year

The operational momentum behind the 2026 program is significant, with multiple drill rigs and geophysical programs either underway or imminent:

The addition of a second diamond drill rig represents a meaningful escalation of drilling activity. Diamond drilling produces core samples with significantly more geological information than RC drilling, allowing the company to better understand the geometry, grade distribution, and continuity of mineralisation — particularly within the high-grade zones now confirmed by DAN26008.

In addition, the planned downhole electromagnetic (DHEM) and ground-based induced polarisation (IP) surveys will help focus drilling into the highest-grade areas identified through this first phase of the regional campaign, potentially improving capital efficiency in subsequent drilling.

The Investment Thesis: A Rapidly Scaling Copper System in a Proven Address

White Cliff Minerals is systematically demonstrating that the Danvers copper system is substantially larger and more complex than the historic 1967–68 estimate could have captured. Several factors distinguish the current situation:

1. Grade quality is holding at scale. As drilling has stepped out northeast along the fault zone, grades have not diminished — they have increased. DAN26008, the furthest northeast step-out with confirmed assays, has delivered the best results of the program. This is the opposite of the dilution trend that frequently undermines exploration stories as systems are extended.

2. Both fault contacts are now mineralised. The identification of significant bornite mineralisation on the southeastern contact in DAN26015 doubles the exploration potential of the fault zone's width. Previously, the northwestern contact was the primary exploration focus. Now, both flanks of a >10km fault system are open targets.

3. Processing performance is already established. The April 2026 metallurgical testwork confirmed industry-leading recovery rates (>95% Cu, >93% Ag) via conventional flotation on Danvers material. This removes a significant uncertainty that exploration-stage companies frequently face and supports the economic potential of any future resource definition.

4. The system remains wide open. DAN26008 is reported to be open at depth and towards surface. The gap between current northeastern drilling and the known Danvers 1 high-grade zone has not yet been fully closed. Every hole drilled into the Teshierpi Fault Zone to date in 2026 has returned copper sulphides.

5. Scale of the geological address. The Teshierpi Fault Zone runs for more than 10km. Only 2.6km of strike has been drill-tested in total. The geophysical work already conducted — including the 2025 HeliTEM and MobileMTd surveys — has identified additional conductivity anomalies that have not yet been drilled. The system, therefore, has a long exploration runway ahead.

Why Investors Should Keep a Close Eye on White Cliff Minerals

The combination of high-grade drill results, an expanding mineralised footprint, a newly discovered structural zone, imminent diamond drill programs, and confirmed metallurgical performance makes White Cliff Minerals one of the more substantive copper exploration stories on the ASX at this stage of its program.

The near-term catalyst pipeline is dense — assay results from visually mineralised holes (including DAN26013, DAN26014, and DAN26015) are expected within four weeks, diamond drill programs are commencing shortly, and geophysical survey quotations are being received that will sharpen future drill targeting. Each of these represents a potential news flow event with the capacity to materially advance the market's understanding of the Danvers system's scale and grade profile.

The White Cliff Minerals Danvers copper drill results in Nunavut Canada continue to impress, as the company systematically proves up a large-scale, high-grade copper system in Canada's Nunavut territory. With DAN26008 delivering the program's best results yet, a new southeastern fault contact opened for exploration, and multiple drill rigs about to be active simultaneously, the next several weeks of results could be transformative for understanding the true scale of this copper system. Investors with an interest in copper exploration should, however, ensure they conduct their own due diligence and closely monitor the forthcoming assay releases.
