en.Wedoany.com Reported - White Cliff Minerals Ltd (ASX:WCN) has confirmed another high-grade copper discovery at its Rae copper project in Nunavut, Canada, with the latest assay results identifying a copper mineralized zone near the Teshierpi fault zone. The discovery comes from reverse circulation drill hole DAN26015 at the Danvers target, which returned 79.24 meters grading 1.59% copper from a depth of 67.06 meters, including a high-grade interval of 24.38 meters grading 3.05% copper from 120.4 meters.
This result confirms mineralization exists beyond the main Teshierpi fault zone, indicating that copper mineralization is not confined to a single structure. The newly discovered mineralized zone runs parallel to this northeast-southwest trending fault zone, which extends over 10 kilometers across the project area, with drilling confirming copper mineralization in the contact zones on both sides of the regional fault. The result also opens up new exploration targets in areas of magnetic and resistivity lows, broadening the company's target model at Danvers.
The 2026 regional drilling program is using wide-spaced reverse circulation holes, typically spaced 300 to 400 meters apart, to test the broader Teshierpi system. Assay results have now confirmed a mineralized strike length exceeding 3.1 kilometers, with visually observed copper sulfide mineralization extending over 6 kilometers, covering more than half of the interpreted geophysical anomaly. Other drill holes also show expansion potential: DAN26024 returned a total copper sulfide interval of 67.05 meters, while DAN26022 observed a total copper sulfide interval of 47.55 meters in the hole, including up to 5% visible bornite. DAN26014 returned 16.77 meters grading 0.87% copper from 233.17 meters, including a higher-grade interval of 4.57 meters grading 1.89% copper, which remains open at depth; this hole also returned 18.29 meters grading 0.15% copper from 109.73 meters. DAN26013 returned 1.52 meters grading 0.32% copper. Previously, DAN26012 had returned 19.81 meters grading 6.64% copper.
White Cliff Minerals Managing Director Troy Whittaker stated that DAN26015 is a significant result, confirming another high-grade copper discovery outside the main Teshierpi fault zone. He noted that the copper zone around Danvers 1 is expanding substantially, with new drilling extending the system 462 meters to the southwest and 686 meters to the northeast, and identifying a parallel mineralized zone 606 meters north of DAN26022. These results from wide-spaced drilling directly demonstrate the strength of the Teshierpi copper system and the effectiveness of target delineation. The company has now deployed a second diamond drill rig on site to follow up on previous high-grade results such as DAN26012, aiming to obtain structural information and guide future expansion drilling.
The Rae copper project is located in Nunavut, northern Canada, and contains multiple high-grade copper occurrences, with mineralization types including chalcocite-dominated vein and breccia systems, lava flow top replacement, and sediment-hosted stratiform copper. The Danvers prospect within the project hosts a historical resource estimate of 4.16 million tonnes of ore grading 2.96% copper. The company is focused on defining and expanding copper mineralization across the project area, including Danvers-style volcanic-hosted copper deposits and other sediment-hosted copper targets. Upcoming work includes oriented diamond core drilling, scissor holes cutting across key 2026 RC holes, infill and expansion drilling around new discoveries, and further exploration along the Teshierpi fault zone.
