Edge Copper Intersects 290 ft at 0.40% CuT in Hole ZND0028 Beyond the PEA Design Pit at the Northwestern End of Zonia

Edge Copper Intersects 290 ft at 0.40% CuT in Hole ZND0028 Beyond the PEA Design Pit at the Northwestern End of Zonia Canada NewsWire VANCOUVER, BC, July 29, 2026 ZND0028 includes 50 ft at 1.69% CuT and intersects oxide mineralization well below the modeled base of oxide; 27 holes reported to date continue to reinforce continuity and expansion potential VANCOUVER, BC, July 29, 2026 /CNW/ -- Edge Copper Corporation (TSXV: EDCU) ("Edge Copper"or the"Company") is pleased to report assay results from seven additional diamond drill holes completed as part of its ongoing drill program at the Company's 100%-owned Zonia Copper Project ("Zonia" or the "Project") in Arizona. The principal result in this release is ZND0028, drilled near the northwestern end of the current PEA Design Pit. The hole returned 290 ft grading 0.40% CuT from 441 ft, including 50 ft grading 1.69% CuT, together with a separate 45 ft interval grading 0.45% CuT from 332 ft. As shown in Figure 2, ZND0028 intersected oxide mineralization beyond the pit limit as well as below the currently modeled base of oxide. This provides an important new data point for evaluating the potential depth and extent of the oxide mineralization at the northwestern end of the deposit. Final interpretation will incorporate follow-up drilling, sequential copper analyses and additional geological and resource modeling. The other holes reported today were drilled primarily as infill and returned broad intervals of oxide mineralization that reinforce continuity within the current mineral resource area. These results bring the total number of holes reported from the current program to 27. Taken together, the 27 holes reported to date are meeting the program's objectives: increasing confidence within the known resource and identifying areas where the current model may understate the extent of the oxide system. ZND0028, together with other broad northern intersections, supports the Company's evolving interpretation that the northern and northwestern limits remain incompletely defined. Drilling is now shifting toward systematic perimeter testing of hanging-wall and footwall contacts and continuity along strike, up-dip and down-dip. The full significance of the results will be evaluated as additional drilling, assays and modeling are completed. Drill Hole Highlights ZND0028 returned 290 ft grading 0.40% CuT from 441 ft, including 50 ft grading 1.69% CuT, plus a separate 45 ft interval grading 0.45% CuT from 332 ft — extending oxide mineralization beyond the current PEA Design Pit at the northwestern end of the deposit and intersecting mineralization well below the modelled base of oxide. ZND0011 returned 350 ft grading 0.31% CuT from 80 ft, including 220 ft grading 0.37% CuT — a strong infill result that confirms historical drill hole data in this part of the deposit. ZND0037 returned 575 ft grading 0.26% CuT from 10 ft, including 195 ft grading 0.35% CuT. ZND0020 returned 472 ft grading 0.22% CuT from 45 ft, including 80 ft grading 0.35% CuT. "These results continue to confirm the continuity and grade of the oxide system at Zonia," said Gil Clausen, Chair and CEO of Edge Copper. "ZND0028 is an important boundary result. It extends mineralization beyond the northwestern limit of the current PEA Design Pit and well below the modeled base of oxide, including 50 ft grading 1.69% CuT. Together with other broad northern intersections, it is beginning to change our working view of the potential scale of the oxide system in this area. More drilling and modeling are required, but ZND0028 is a clear priority for follow-up." ZND0028 Highlights Northeast Expansion Potential ZND0028 was drilled near the northwestern limit of the current resource and PEA Design Pit. Figure 2 shows the location of the drill hole outside the PEA pit design. Together with other drill holes in this northern area, this hole strengthens the Company's working interpretation that oxide mineralization may extend farther and deeper than reflected in the PEA model at the northwestern end of the deposit. This interpretation remains preliminary and subject to sequential copper analyses, follow-up drilling and additional modeling. The remaining holes were designed principally to test continuity, grade distribution and geological interpretation within the current resource. ZND0011, ZND0020, ZND0022 and ZND0037 add data to the Company's geological and resource models, while ZND0048 adds another mineralized intersection at the northern end of the deposit. The results support increasing confidence in the current resource, potential future conversion of Inferred Mineral Resources to the Indicated category, and evaluation of expansion potential beyond the current PEA Design Pit. Hole locations are shown in Figure 1, the ZND0028 cross section in Figure 2, and complete drill-hole tables in Appendix A. The PEA Design Pit referenced in the following figures is based on the Company's current technical report for Zonia titled National Instrument 43-101 Revised Technical Report 2026 Preliminary Economic Assessment Yavapai County, Arizona, USA with a Report Date of April 7, 2026. The results of the Company's preliminary economic assessment ("PEA") are preliminary in nature and include Inferred Mineral Resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that the preliminary economic assessment will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Program Outlook The Zonia drill program has progressed from infill drilling, aimed at converting Inferred Mineral Resources to the Indicated category, to perimeter drilling designed to define the edges of, and expand, the oxide system, as demonstrated by the high-grade intersection in ZND0028. Over the coming months, Edge Copper plans to: continue drilling around the deposit perimeter to define the edges of, and expand, the mineralized system, establishing contacts where margins are faulted; incorporate ZND0028 and other the resource expansion holes into the internal geological and resource model and determine the remaining infill drilling required for future resource evaluation and mining analysis; report initial assay results from drilling into the sulfide zone beneath the oxide deposit in Q3 2026, subject to completion of QA/QC review and technical interpretation; commence metallurgical test work in late August 2026 on representative material from eight completed large-diameter drill holes spanning the principal mineralized domains and lithologies; and continue advancing the work required to support an updated Zonia Mineral Resource estimate in the fourth quarter of 2026. The Company expects to continue reporting drill results as assays, QA/QC review and geological interpretation are completed. QA/QC All drill samples were collected under the supervision of the Company's geological staff in accordance with industry-standard quality assurance and quality control ("QA/QC") procedures. Samples are from HQ-diameter core. Core is scanned and logged by the Company's geology team before being cut. Half-core HQ samples are prepared for assay, and the remaining material is retained at site for future reference. The Company's QA/QC program includes the insertion of certified reference materials, blanks and duplicate samples at regular intervals within the sample stream. The Company also conducts ongoing reviews of laboratory QA/QC performance to ensure analytical reliability and accuracy. Assay samples were picked up directly from site by Skyline Assayers and Laboratories ("Skyline") and transported to Skyline's laboratory facility in Tucson, Arizona for preparation and analysis. Skyline is accredited and independent of the Company. Sample preparation included drying, crushing, splitting and pulverizing prior to analysis. Copper assays were determined using Skyline's single-element assay method, consisting of three-acid digestion followed by atomic absorption spectroscopy (AAS) determination for total copper. Significant intervals reported in this news release were calculated using a 0.10% CuT cut-off. All drill core is oriented where possible. Drill holes in the current program were drilled at inclinations of approximately -45 to -58 degrees and generally oriented towards the southeast, broadly orthogonal to the interpreted strike and dip of the mineralized system, associated foliation and the major bounding fault structures. Based on the current geological interpretation and drill geometry, intervals reported in this news release are interpreted to represent approximate true thicknesses.
