Edge Copper drills oxide results at Zonia

Canada NewsWire

VANCOUVER, BC , Sept. 14, 2026 /CNW/ -- Edge Copper Corporation (TSX: EDCU) ("Edge Copper" or the "Company") is pleased to report assay results from eight additional diamond drill holes completed as part of its ongoing approximately 54,000-foot drilling program at the Company's 100%-owned Zonia Copper Project ("Zonia" or the "Project") in Arizona. These results bring the total number of holes reported from the current program to 45.

The principal result is from hole ZND0030, drilled in the central part of the deposit beneath several shallow historical holes. It returned 140 ft grading 0.45% total copper (CuT) from 0 ft, including 80 ft grading 0.63% CuT from 20 ft. A separate interval returned 340 ft grading 0.30% CuT from 400 ft, including 165 ft grading 0.40% CuT from 410 ft. Figure 2 shows the ZND0030 cross section.

ZND0030 adds two broad copper intervals in an area previously tested mainly by shallow historical holes. The deeper mineralized zone in this hole demonstrates that oxide copper mineralization extends over approximately 550 ft of vertical extent in the central area of the deposit (see Figure 2).

Drill Hole Highlights

ZND0030 returned 140 ft grading 0.45% CuT from 0 ft, including 80 ft grading 0.63% CuT from 20 ft, plus an additional interval of 340 ft grading 0.30% CuT from 400 ft, including 165 ft grading 0.40% CuT from 410 ft.

ZND0060 returned 248 ft grading 0.30% CuT from 553 ft, including 156 ft grading 0.37% CuT from 598 ft. The reported oxide and mixed mineralization is on the northwestern margin of the deposit, beyond the current PEA design pit (Figure 3 shows the ZND0060 cross section).

ZND0034 returned 465 ft grading 0.26% CuT from 0 ft in the northern part of the deposit, including 160 ft at 0.33% CuT from 105 ft.

ZND0039 returned 623 ft grading 0.23% CuT from 2 ft, including 125 ft grading 0.34% CuT from 195 ft in the northern part of the deposit.
