Edge Copper drilling confirms broad oxide copper mineralization at Zonia

Canada NewsWire VANCOUVER, BC , May 19, 2026 /CNW/ -  Edge Copper Corporation (TSXV: EDCU) (" Edge Copper " or the " Company ") is pleased to report initial assay results from its ongoing approximately 54,000-foot diamond drilling program at its 100%-owned Zonia Copper Project, located in Arizona. The first eleven holes reported from the program confirm broad, near-surface oxide copper mineralization within, adjacent to, and locally beyond, the current pit shell used for the Company's preliminary economic assessment (the "Pit Shell") and support the Company's view that Zonia has meaningful resource-growth potential. Drill Hole Highlights ZND0014 returned 621 ft grading 0.23% CuT from 79 ft, including 77 ft grading 0.34% CuT and 174 ft grading 0.36% CuT.

ZND0003 returned 247 ft grading 0.36% CuT from 170 ft and intersected oxide copper mineralization below the currently modelled base of oxide. ZND0002 returned 306 ft grading 0.25% CuT from 24 ft, including 78 ft grading 0.38% CuT. ZND0009 returned 236 ft grading 0.29% CuT from 504 ft, including 90 ft grading 0.43% CuT.

ZND0019 returned 264 ft grading 0.22% CuT from 266 ft, including 67 ft grading 0.45% CuT. "These initial results are meeting the objectives of the program: increasing confidence in the existing resource model while identifying opportunities to expand the oxide copper system," said Gil Clausen, Chair and CEO of Edge Copper. "Zonia has the potential to be more than a fixed resource inventory.

The current program is designed to evaluate meaningful resource growth, including an internal objective of assessing the potential for approximately 50% resource growth, which, if supported by additional drilling, metallurgy, resource modelling and future engineering studies, could support evaluation of higher production rates and longer mine life scenarios. These first holes are an encouraging step." D
