Edge Copper presents staged development plans for Zonia copper project

• Edge Copper expects a materially larger oxide mineral resource estimate for its Zonia project in Arizona in January 2027.
• An updated oxide preliminary economic assessment is expected in late Q1 2027, incorporating the expanded resource base.
• The March 2026 assessment estimated an after-tax net present value of US$ 488 million at an 8% discount rate.
• All 13 sulfide drill holes intersected mineralization across approximately 9,800 feet of strike beneath the oxide deposit.
• Planned 2027 drilling will test sulfide continuity and scale, assessing whether oxide development could support a later sulfide project.
