The Rae project covers a remote copper exploration district in Nunavut, Canada.
By Penny Langford
Hancock Prospecting has agreed to invest about A$8.77 million in White Cliff Minerals, taking an expected 13.5% stake in the Australian-listed copper explorer and providing funding for an expanded drilling campaign at the Rae Copper Project in Nunavut, Canada.
The proposed placement would see Hancock subscribe for 515.79 million new White Cliff shares at A$0.017 each, according to a White Cliff ASX announcement. The transaction remains subject to shareholder approval under ASX Listing Rule 10.11.
The investment gives White Cliff additional funding to test the scale and continuity of copper mineralisation across Rae, while giving Hancock exposure to an early-stage project in a jurisdiction that is becoming increasingly important to North American and global critical-minerals supply chains.
Placement still requires shareholder approval
White Cliff said the subscription agreement with Hancock Prospecting is conditional on approval at an extraordinary general meeting and on ASX not indicating that it will refuse quotation of the new shares.
The company expects to hold the meeting on or about Oct. 19, with completion expected three business days after the meeting if the required conditions are satisfied.

The issue price is equal to White Cliff’s closing share price on the trading day before the placement was announced, the company said.
White Cliff Managing Director Troy Whittaker described the investment as a significant milestone for the company and said it would allow the explorer to accelerate work across several targets at Rae. His comments were included in the company’s regulatory announcement.
The placement proceeds, combined with White Cliff’s existing cash reserves, will be directed mainly toward drilling and geological programs. The company has not presented the Rae project as a defined economic deposit, and further exploration, resource estimation, metallurgical testing, permitting and infrastructure assessment will be required before any development decision can be made.
Rae drilling program to expand across Danvers
White Cliff plans to focus the initial work on the Danvers area, where previous drilling has identified copper and silver mineralisation across multiple zones.
At Danvers 1, the company intends to increase drill density around the area with the strongest results to date. The stated objective is to define an exploration target and move toward a maiden mineral resource estimate.
The company also plans systematic step-out drilling at Danvers 2 and Danvers 3. Those programs are intended to test the continuity and lateral extent of mineralisation beyond the most advanced drill sections.
White Cliff plans to expand drilling across the Danvers zones and regional Rae targets.
White Cliff reported several high-grade copper intersections from the Danvers system, including:
- 175 metres at 2.5% copper and 8.66 grams per tonne silver
- 90 metres at 4% copper and 7.5 grams per tonne silver
- 58 metres at 3.08% copper and 13.3 grams per tonne silver
- 105 metres at 2.25% copper
- 19.81 metres at 6.64% copper, including 7.62 metres at 11.38% copper, from a 2026 hole at Danvers
The reported intervals are exploration results and do not constitute a mineral resource or reserve. Their significance will depend on continuity, geometry, recoverability and the amount of mineralisation that can eventually be converted into a compliant resource.
White Cliff said drilling at Danvers 2, more than 5 kilometres along strike from Danvers 1, returned a 15-metre intersection grading 4.8% copper. At Danvers 3, the company reported intersections of 20 metres at 6.64% copper, 23 metres at 6.18% copper and 79.24 metres at 1.59% copper.
The next phase of drilling will test whether those results are part of a connected mineralised system or represent separate zones requiring different exploration and development approaches.
Sediment-hosted copper adds a second exploration track
The Rae program is not limited to the Danvers vein-hosted copper system.
White Cliff is also advancing sediment-hosted copper targets, including the Hulk area, where the company says drilling has confirmed mineralisation along the contact between the Rae Group and Husky Creek Formation.
That contact is interpreted by White Cliff as a regional redox boundary and unconformity that may control the distribution of copper mineralisation. The company has described the mineralisation as a laterally extensive, sheet-like horizon that is generally between 2 and 30 metres thick.
White Cliff reported that 2025 drilling returned 3.5 metres at 7.2% copper and 25 metres at 0.6% copper. During the 2026 program, the company said visible chalcopyrite was intersected in three holes and that mineralisation had been extended 3.7 kilometres east of a previous hole.
The company estimates that the interpreted sediment-hosted copper footprint covers about 6.3 square kilometres, although further drilling will be needed to establish the grade distribution, thickness and continuity of the system.
An ultra-high-resolution airborne geophysical survey is planned to support target generation across the sedimentary copper areas. White Cliff also intends to deploy downhole electromagnetic equipment to refine targets around known mineralisation and identify extensions that may not be visible from surface geology alone.
Regional targets could widen the project scope
White Cliff said a review of regional geophysical data has identified signatures that resemble the Danvers system at the Thor, Rocket, Vision and Stark targets.
Those areas are expected to form part of an accelerated regional drilling and follow-up program. The outcome could determine whether Rae is best understood as a single advanced prospect or as a broader copper district with several mineralised centres.
That distinction is important operationally. A single discovery may require intensive drilling around a defined deposit, while a district-scale exploration model requires broader logistics, staged target ranking and longer-term camp and access planning.
Rae is in a remote part of Nunavut. White Cliff’s project information places the area about 75 kilometres from the coastal town of Kugluktuk and a short flight from Yellowknife, the regional mining and services hub. The location provides access to established regional aviation routes but also leaves the project exposed to seasonal operating constraints, weather disruption and high mobilisation costs.
Field mapping and sampling remain important as White Cliff tests targets beyond the main Danvers zones.
Hancock deal highlights strategic interest in copper exploration
Hancock Prospecting is one of Australia’s largest privately owned mining companies, with interests across iron ore, lithium, copper and other resources. Its proposed investment in White Cliff is a minority placement rather than an acquisition of the Rae project.
That structure allows White Cliff to retain control of its exploration program while bringing in a financially significant shareholder. For Hancock, the placement provides exposure to Rae without committing immediately to project-level construction or a full corporate takeover.
The deal also illustrates the growing interest in earlier-stage copper assets as miners and private resource groups seek potential future supply. Copper demand is being supported by electricity networks, grid investment, data centres, electric vehicles and renewable power infrastructure, while new mine development continues to face long permitting timelines and rising capital requirements.
A strategic investment, however, does not remove the technical and commercial risks facing an exploration project. White Cliff will need to demonstrate that the reported high-grade intervals are continuous, that the mineralisation can support a viable mining method and that future processing and transport options are practical in the Arctic environment.
What happens next
The immediate milestone is shareholder approval for the placement. If approval is secured, White Cliff expects to receive the funds shortly afterward and begin expanding the Rae drilling and exploration program.
The most important operational markers will be:
- Completion of the Hancock placement following the extraordinary general meeting.
- Additional Danvers 1 drilling to support an exploration target and potential maiden resource estimate.
- Step-out results from Danvers 2 and Danvers 3 to test the scale of the high-grade copper system.
- Geophysical and electromagnetic results from the sediment-hosted copper targets.
- Follow-up drilling at Thor, Rocket, Vision and Stark to assess the regional exploration model.
- Further technical studies needed to determine metallurgy, infrastructure requirements and potential development pathways.
For now, the Hancock transaction provides White Cliff with funding and a strategic shareholder at a time when copper explorers are seeking to establish large, high-grade discoveries. Its longer-term importance will depend on whether the expanded program can convert promising drill results into a coherent, economically relevant resource at Rae.
