Southern Copper’s Q3 2024 earnings explode higher: copper output up 11%, zinc up 91%, silver up 22%, driving a 45% net income leap to $897 million and a 57% EBITDA margin—here’s what investors need to know now.
Copper Production Rebounds: Peru and Mexico Lead the Charge
Southern Copper delivered a standout third quarter, with total copper production climbing 11% sequentially to 252,219 tons. Peruvian operations surged 18% quarter-over-quarter, fueled by higher throughput at Cuajone and improved ore grades at Toquepala. Mexican mines added a 7% boost, led by Buenavista and La Caridad.
Management now guides 2024 full-year output to 975,000 tons—up 7% year-over-year—and pencils in 978,300 tons for 2025, effectively locking in a new elevated baseline.
Zinc and Silver Output Rocket Higher
Zinc stole the show with a 91% year-over-year jump to 31,078 tons, almost entirely driven by the new Buenavista Zinc concentrator that alone contributed 14,453 tons. Silver mined production vaulted 22% higher, while the average realized price leapt 25% to $29.43/oz. Refined silver slipped 3% on La Caridad refinery downtime, but the net effect is still a 46% surge in silver sales value.
Margins Expand as Costs Stay Flat
Unit economics improved despite inflationary headwinds. Operating cash cost before by-product credits fell 9% quarter-over-quarter to $1.95/lb, while the cost after credits held steady at $0.76/lb. A $639 million by-product credit—$1.19/lb of copper—was powered by strong zinc and sulfuric acid pricing that offset weaker molybdenum.
The result: adjusted EBITDA margin widened to 57% from 52% a year ago, and net income margin hit 31% versus 25% in Q3 2023.
Cash Flow and Balance Sheet: Funding Growth Internally
Operating cash flow rocketed 37% to $1.44 billion, fully covering the quarter’s $264 million in capex. Nine-month spending rose 5% to $792 million—31% of net income—leaving ample room for the recently declared $0.70/share cash dividend plus a 0.0062-share stock dividend payable 21 November.
Management flagged a likely debt issuance in coming quarters to refinance a $500 million bond maturity and pre-fund the Tia Maria project, but stressed no structure is yet locked.
Tia Maria and the 2027 Production Kicker
Construction at the long-delayed Tia Maria project in Peru is accelerating: 400+ employees are on-site, earth-moving contracts are being tendered, and the 2025 capex budget is set at $363 million. First production is still slated for 2027, adding 120,000 tpy of copper at an estimated cash cost of $1.16/lb—well below current spot prices near $4.30/lb.
A refreshed total-project capex of roughly $1.8 billion (up from the 2016 estimate) includes new infrastructure such as a desert-to-port road designed to bypass valley communities and reduce social risk.
Los Chancas Disruption: Illegal Mining Clouds 2026 Upside
Progress at the Los Chancas copper-gold project remains stalled by illegal mining incursions. Coordination with national police is ongoing, but management concedes resolution may not occur until Q1 2025. Until access is restored, Los Chancas’ 40,000-meter infill drill program and environmental studies stay on ice—pushing back a potential 2026 production uplift.
Mexican Regulatory Overhang: Minimal Near-Term Impact
Recent changes to Mexico’s mining laws have not materially affected Southern Copper; existing concessions are grandfathered. Open-pit restrictions under debate would apply only to new projects, leaving the company’s Buenavista expansion and El Arco development timeline intact.
Investor Takeaway: Margin Leader With Visible Growth
Southern Copper is trading at a premium for good reason: it combines the industry’s lowest cash costs with the clearest production growth pathway through 2027. The Q3 print confirms that Peru recoveries, Mexican zinc start-ups, and rising by-product prices are more than offsetting any cost inflation. Risks remain—water security in Sonora, social licensing in Peru, and molybdenum price volatility—but the balance sheet is unlevered and cash flow is surging.
With spot copper above $4/lb and the company guiding to flat 2025 output at world-beating margins, investors are looking at a 30%+ free-cash-flow yield at current prices—one of the highest in the large-cap metals space.
