Ivanhoe Electric Releases 2026 PFS for Santa Cruz Copper Project

What Happened
Ivanhoe Electric (IE) announced on September 23, 2026 that it released an S‑K 1300 Preliminary Feasibility Study & Technical Report Summary (the “2026 PFS”) for its Santa Cruz Copper Project (Arizona) and furnished a press release and investor‑call slideshow (Exhibits 99.2 and 99.3) in an 8‑K. The PFS, prepared by third‑party qualified firms (led by BBA and Worley among others), reports Probable Mineral Reserves and updated Mineral Resources, a life‑of‑mine plan using underground mining with heap‑leach + SX/EW processing, and full economic modeling under S‑K 1300 standards.

Key Details

• Mineral Reserves (Probable): 140,129 kt @ 1.08% Cu (contains ~1,519 kt of copper) — estimate current to Sept. 23, 2026.
• Mineral Resources (Indicated + Inferred, inclusive): Indicated ~326.45 Mt @ 0.95% Cu (contains ~3,104 kt Cu); Inferred ~422.02 Mt @ 0.79% Cu (contains ~3,332 kt Cu).
• Production & mine life: 24‑year LOM (construction 2027–mid‑2029; production through 2052); average annual cathode ~58,385 t/y (first 15 years ~74,722 t/y).
• Costs & economics: Initial capex US$1.43B; sustaining capex US$1.42B; total LOM capex US$2.85B. LOM operating costs US$4.53B. C1 cash cost US$1.47/lb Cu; AISC US$2.28/lb Cu. After‑tax IRR 18.7% and after‑tax NPV (8%) US$1.52B (base copper price US$4.75/lb used in model).
• Processing & recovery: Heap‑leach + solvent extraction/electrowinning to produce LME‑grade cathode; life‑of‑mine weighted recovery ~92.3% to cathode.
• Other: Mining method = underground longhole stoping with paste backfill; peak production target ≈20,000 t/d; water rights include ~3,600 acre‑ft/year grandfathered water rights.

Why It Matters
The 2026 PFS provides an S‑K 1300‑compliant technical and economic baseline for investors: it quantifies reserves/resources, capital and operating requirements, production profile, and projected returns under specified price and recovery assumptions. Key takeaways for investors are the sizeable Probable Reserves, multi‑decade production profile, estimated mid‑single‑digit billion dollar cashflow potential (pre/post tax NPVs and IRRs provided), and substantial upfront and sustaining capital needs (~US$2.85B). The study also identifies permitting, price, recovery, and technical factors that could affect outcomes and notes the company will discuss results on an investor call (slideshow furnished).
