White Cliff Expands Danvers 1 Copper System 480% in Canada

White Cliff has fast-tracked infill drilling at Danvers. Whittaker said the company would test the gaps between existing holes and target broader breccia development. "Oriented core is strengthening that model, giving us a more predictive framework for targeting the parts of the system with the greatest potential to develop width and higher grades," he said. The company is also running depth drilling to convert the 4.75-kilometre trend into a more continuous geological model.

The drilling is part of a dual strategy: expand the known surface area of the deposit while guiding exploration toward high-grade, high-tonnage sedimentary targets. Recent digitisation of historical data, combined with the 2025 drilling campaign, identified further copper mineralisation outside and below the previous estimate.

The Danvers 1 mineralisation sits at a 950-metre strike length. Within that, 375 metres represents the previously released non-JORC compliant estimate of 4.16 million tonnes grading 2.96% copper. Whittaker said the depth extension at Danvers 3, combined with the latest step-out results, was building a picture of a large, high-grade copper system with clear future resource potential.

A second batch of assays from the remaining step-out holes is still pending. The company has not given a timeline for the next results.
