Cascade Copper Corp. Confirms High-Grade Results from Copper-Plateau Project Resampling

Vancouver, British Columbia — November 12, 2026 — Leads & Copy — Cascade Copper Corp. (CSE: CASC/FRA: 91O) has announced positive results from a drill core resampling exercise conducted during the late summer field season. The resampling aimed to validate previous high-grade results from historic drilling campaigns in 2006 and 2008 at the Company's 100% owned Copper-Plateau Project.

The initiative involved four readily available sections from historic drill holes, which were validated, quartered, and sent for assay. The results confirmed the accuracy of the historical drilling data, bolstering confidence for future exploration planning.

The Copper-Plateau Project, located approximately 40 kilometers east of the Copper Mountain Mine (TSX:HBM), spans roughly 2,789 hectares and is accessible by road. The project's geological setting indicates potential for molybdenum, gold, and copper mineralization. This project is situated within the Quesnel Terrane, an area known for significant mineral deposits, including the Copper Mountain Mine to the southwest and Teck's Highland Valley Copper Mine to the northwest. Kodiak Copper's MPD project is located 40km to the west.

Shannon Baird, Cascade's Vice President of Exploration, expressed satisfaction with the resampling outcomes. "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," Baird stated. He noted that the initial selection of drill intervals was based on ease of access, and future resampling efforts will require more extensive sorting of core pallets.

Future plans for the Copper-Plateau Project include an Induced Polarization (IP) survey over historic zones of interest. Additionally, Cascade Copper is seeking a diamond drill permit to validate historic holes and further expand known zones of mineralization.

The resampling protocol involved laying out historic core boxes, measuring depth markers, and comparing core logs to historic records. Core was sawn, with one quarter retained for reference and the other placed in sample bags. Samples were sealed, grouped, and couriered to Actlabs in Kamloops, BC, a fully accredited laboratory. Analysis methods included a 4-acid near-total digestion with ICP-MS and ICP-OES techniques. Over-limit copper samples were analyzed using the standard 4-Acid ICP-OES protocol, while gold analysis was performed via 30g fire assay with Atomic Absorption finish.
