Southern Copper combines a 52-year reserve life and negative net cash costs with a valuation that leaves little margin of safety.
Overview
Southern Copper is a globally significant, vertically integrated copper producer with low-cost, long-life mines in Peru and Mexico. Its moat rests on second-quartile C1 costs, substantial molybdenum, silver and zinc credits, and approximately 109.0 billion pounds of reserves supporting a 52-year average mine life. **Q2 2026 demonstrated exceptional operating leverage:** revenue increased 40.6% year over year to $4,289.0 million, adjusted EBITDA rose 59.5% to $2,856.0 million, and EBITDA margin expanded to 66.6%. This occurred despite a 3.5% decline in mined copper production, because LME copper averaged $6.04/lb and COMEX copper $6.16/lb. Management raised 2026 copper production guidance to 917,000 tonnes and expects Peruvian volumes to recover in the second half. **The core investment conflict is asset quality versus valuation:** the DCF produces $96.67 per share versus the August 10 price of $200.11, while the probability-weighted FY2031 target is $189.35. Catalysts include Tía María beginning operations in late 2027, the Buenavista zinc concentrator, a 320,000-tonne estimated 2026 copper deficit and sustained dividends, but the current price already assumes strong copper prices and largely flawless project execution.
