Vancouver, British Columbia – November 12, 2026 – TheNewswire - Cascade Copper Corp. announces it has received the results of a drill core resampling exercise from the late summer field season. What: Four readily available sections from historic holes validated and quartered for assay, Sampling confirms previous high grade results from historic drilling in 2006 and 2008. When: During the late summer field season, members of Cascade’s management were in the area prospecting and executed the re-sampling. Significance: The 100% owned Copper-Plateau Project (*no NSR) is road accessible, approximately 2,789 ha and 40km due east of the Copper Mountain Mine. The Project benefits from exposure to molybdenum, gold and of course, copper. Next Steps: IP survey over historic zones of interest, Receipt of diamond drill permit to validate historic holes and expand known zones of mineralization. Shannon Baird, Cascade’s Vice President of Exploration remarks; “We were fortunate to have access to the vast majority of the historic drill core from the Copper Plateau project and that we were able to resample intervals through quartering. The resampling results are quite comparable to the original numbers and this gives us added confidence to rely on these historic numbers for further drill planning. Drill intervals were selected by ease of access and order of the existing loaded pallets; future re-sampling will require greater manpower to sort through the pallets of core and organize core boxes in advance for validation and subsequent cutting.” Click Image To View Full Size Figure 1: Example Historic Core Prior to Resampling Table 1: Highlights of resampling sections of four holes from historic core at Copper Plateau Click Image To View Full Size *CuEq values are calculated using the following commodity prices and recovery factors:$5.00 Cu, $3750 Au, $50 Ag, $40 Mo and 90% recovery for Cu, 65% recovery for Au, 70% recovery for Ag and 65% for Mo (values from similar porphyry deposits in south Central BC), Using those values the CuEq% = Cu% + Au g/t x 0.710938 + Ag g/t x 0.010208 +Mo % x 5.2 Figure 2: Example of Historic Core From Hole IS06-10 Prior to Resampling by Quartering Figure 3: Example Core Prior to Quartering Figure 4: Example Core Prior to Quartering Project Location The Copper Plateau Porphyry project is located in south-central British Columbia, between Penticton and Princeton. It is situated south of the former Brenda Copper Mine, which produced 177 million tonnes of ore grading 0.169% Cu and 0.043% Mo between 1970 and 19903. The geological setting is within the Quesnel Terrane which hosts Copper Mountain southwest of Copper Plateau and Teck’s Highland Valley Copper Mine to the northwest. Kodiak Copper’s MPD project lies 40km west of the Project. Click Image To View Full Size ¹: Teck Resources AIF 2024 (https://www.teck.com/media/AIF-2025.pdf) ²:…
