Edge Copper (EDCU) Corporate presentation summary

Project overview and development timeline

• Advancing a 100%-owned Arizona copper project with open pit, heap leach, and SX/EW processing targeting Grade A cathode production.

• Current mineral resource estimate (Jan 2026): 964M lbs indicated and 341M lbs inferred copper, based on historical drilling.

• 54,000 ft drill program underway, with ~44,000 ft completed; updated mineral resource estimate expected Q4 2026.

• Prefeasibility study (PFS) targeted for mid-2027, following updated resource and technical studies.

• Project leverages existing infrastructure and is located in a Tier-1 jurisdiction.

Economic highlights and capital profile

• March 2026 PEA outlines 76M lbs/year average copper cathode production over a 10-year mine life.

• After-tax NPV8% of $488M and IRR of 23.4% at $4.60/lb copper; sensitivity case NPV8% of $1.07B at $5.98/lb copper.

• Initial capex of $524.5M, with sustaining capex of $168.6M and heap leach expansion in year 3 for $27.7M.

• All-in cost (AIC) estimated at $2.47/lb Cu, with average recovery of 72.8% and a low strip ratio of 0.6.

• Competitive capital intensity at ~$13,500/tpa, below peer average.

Exploration and resource growth

• Drilling confirms broad oxide intervals and continuity, with significant intercepts beyond current pit limits.

• Deposit remains open along strike and at depth, with expansion potential at western, central, and eastern porphyry centers.

• Updated Q4 2026 MRE aims for ~50% resource increase, incorporating new drilling data.

• Selected holes: ZND0028 intersected 290 ft at 0.40% CuT (including 50 ft at 1.69% CuT) beyond PEA pit.

• Cross-sections show mineralization extending beyond current resource boundaries, supporting further expansion.
