About this update from Cascadia Minerals Ltd

VANCOUVER, BC, July 7, 2026 /CNW/ - Cascadia Minerals Ltd. (" Cascadia ") (TSXV: CAM) (OTCQB: CAMNF) is pleased to announce the first drill results from its fully-funded 2026 exploration program at the road-accessible Carmacks copper-gold project in central Yukon. Carmacks Drilling Highlights "We are achieving exactly what we set out to do this season. The broad intercept in hole 46 at Zone 2000S demonstrates the potential to significantly extend mineralization outside of the existing resource model," said Graham Downs, President and CEO of Cascadia. "A total of 16 holes, comprising 8,226 m, have been completed this season out of a planned 15,000 m of drilling. This represents the largest drill program on the property since 2007, and the first significant drill campaign targeting expansion of sulphide resources. All of the holes drilled at zones 147 and 2000S have intersected mineralization, with assays received for the 5 holes reported in this release. We will continue to test further growth of the 2000S and 147 zones through step-out drilling, and will soon start drilling to expand Zone 1213, which has seen primarily shallow holes to-date. Crews have also started regional exploration work across the Carmacks property, and initial results have identified a new high-priority target for further follow-up."
