First Quantum Minerals has outlined a US$5.25B development plan for the Taca Taca copper project in Salta, Argentina, framing the investment as part of a broader strategic pivot toward long‑term supply security and portfolio resilience in copper. The plan comprises US$4.23B for base‑case development and US$1.02B for expansion capacity.
Project scope and scale
- Phased ramp‑up: Initial processing capacity of 40Mt/y, expanding to 60Mt/y in year five.
- Reserves and mine life: 1.99Bt Proven & Probable at 0.42% Cu and 0.09g/t Au, supporting a 35‑year mine life; reserves reflect a +13% increase versus prior assessments, with +9% contained copper and gold.
- Production: Annual copper output >200kt, with peak capacity >320kt/y, placing the asset within the top quartile of global producers at peak.
Processing and technology
- Conventional open‑pit with a flowsheet replicating First Quantum’s large‑scale SAG mill architecture proven at Sentinel and Kansanshi.
- Design includes staged expansion, advanced process control, predictive maintenance, and potential adoption of autonomous haulage and real‑time grade monitoring to reduce execution risk and enable operational best practice transfer.
Multi‑metal revenue profile
- Copper: ~70–75% of revenue at base‑case pricing.
- Gold: ~20–25% (~133koz/y in the first decade; peak ~171koz/y), providing diversification and cash‑flow resilience.
- Molybdenum: ~3kt/y (~3–5% of revenue), aligned with steel and renewable infrastructure demand.
Regulatory framework (RIGI) and timeline
- The project is aligned to Argentina’s Incentive Regime for Large Investments (RIGI), which offers fiscal stability, FX access, duty relief, accelerated depreciation, and streamlined permitting for qualifying projects.
- ESIA completion: H1 2026; RIGI application by July 2027; earliest material spend from 2028; first production targeted for the early 2030s.
Economics and costs
- Base case assumes US$4.50/lb Cu, US$3,000/oz Au, US$18/lb Mo.
- After‑tax NPV (8%): US$5.92B, above total capex of US$5.25B; after‑tax IRR reflects strong leverage to copper prices (every ±10% Cu price shift implies ~±US$1.47B or ±25% NPV swing).
- Costs: First decade C1 cash costs US$0.97/lb, life‑of‑mine US$1.26/lb; AISC ~US$1.60/lb, positioning the operation in the lower quartile of the global cost curve.
- Integrated chlor‑alkali and renewable power access (via grid integration) support the project’s cost and carbon‑intensity profile.
Location and infrastructure
- Salta province, ~55km from the Chilean border at ~3,500m elevation.
- Planned infrastructure includes a 122.5km transmission line connecting to the 345kV Argentina–Chile system, a 5km rail spur to trans‑Andean logistics, and access to Pacific ports via Chile—supporting export optionality and renewable energy sourcing.
Workforce and regional impact
- ~4,000 construction jobs and ~2,000 operational roles; supply‑chain and services multipliers expected across Salta province.
- Programme emphasises community engagement, environmental monitoring, and safety systems consistent with modern ESG standards.
Strategic context
- Following the 2023 closure of Cobre Panamá, Taca Taca serves as First Quantum’s primary growth platform, offering geographic diversification, scale, and multi‑metal revenue resilience with exploration upside (mineralisation remains open at depth and to the south/east).
