Copper, Lithium, and the Race to Build Latin America’s Mines

Latin America holds roughly 60% of the world’s identified lithium resources and produces more copper than any other region on earth, yet the capital now flowing into the Andean belt dwarfs anything the region has absorbed in a generation. A structural copper supply gap is pulling billions of dollars into new projects across Chile, Peru, Argentina, and Ecuador simultaneously, while the lithium triangle is drawing investment from Rio Tinto, Glencore, Posco, and a roster of mid-tier developers racing to lock in position before forecast deficits arrive.

The scale is difficult to overstate. Industry estimates suggest hundreds of billions of dollars in cumulative global copper capital expenditure will be required by 2030 to meet demand growth, and the Andean copper belt is where the geology, the permits, and the capital are converging. What follows maps where that capital is flowing across Latin America’s mining projects, which developments are advancing toward construction decisions, and what the policy and social-licence dynamics mean for investors evaluating jurisdiction risk across the region.

A supply gap that explains everything

The investment cycle now reshaping Latin America’s copper and lithium sectors is not opportunistic. It is structural. Industry analyses estimate that meeting projected global copper demand growth could require US$250-350 billion in cumulative capital expenditure by 2030, and the Andean belt is where the largest share of that spending is concentrating.

The regional pipeline reflects the urgency. Estimates indicate that approximately US$50 billion is already being invested in Latin American copper projects expected to start production before 2030, targeting roughly 3.2 Mt/y of additional output against a current regional base of 7.6 Mt/y.

Regional copper capacity additions targeting the late 2020s could reach approximately 3.2 Mt/y, a 42% increase over today’s 7.6 Mt/y base, if projects advance on schedule.

The resource concentration underpinning this pipeline is stark:

S&P Global copper supply deficit forecasts project a shortfall of approximately 10 million metric tonnes by 2040, with Wood Mackenzie estimating over US$210 billion in new investment required by 2035 alone to meet demand from electrification and AI infrastructure buildout, figures that underscore why the Andean belt is absorbing capital at a pace the region has not seen in a generation.

• Latin America accounts for approximately 60% of the world’s identified lithium resources, concentrated in the lithium triangle spanning Argentina, Bolivia, and Chile
• Chile remains the world’s largest copper producer, with Peru, Argentina, and Ecuador each advancing material project pipelines
• Industry trackers monitor over 3,500 active metals and minerals projects across the region, representing an estimated US$325 billion in total value

The asymmetry between geological abundance and execution capacity is the tension that defines this cycle. The ore is there. The question is whether the permitting regimes, water access, social-licence frameworks, and capital structures can deliver it on the timeline the market needs. That question plays out differently in each jurisdiction.

Ecuador and Argentina are rewriting the Andean copper map

Ecuador: Warintza raises the jurisdiction’s profile

Two years ago, Ecuador barely registered on institutional copper investors’ radar. Warintza changed that. Solaris Resources released a pre-feasibility study confirming a Tier-1 porphyry copper deposit with over 1.3 billion tonnes of mineral reserves, projected capital expenditure of US$3.7 billion, and an estimated mine life of 22 years. A construction decision is targeting approximately 2027.

Lundin Gold has publicly characterised Ecuador as an underrecognised destination for mining investment, a signal that major operators now view the jurisdiction as more than an exploration frontier.

The primary execution risk is not geological. Loma Larga, an approximately US$419 million project, is currently in a critical phase facing community opposition, illustrating how social licence remains the decisive non-geological constraint. Warintza’s path to construction will be shaped as much by community engagement outcomes as by engineering timelines.

Argentina: copper from near-zero to material producer

Argentina currently produces negligible copper. The pipeline suggests that is about to change in a material way.

The Vicuña megaproject carries a reported valuation of US$9.7 billion and has accelerated its initial development phase as of 2026. Pachón, operated by Glencore in San Juan Province, is advancing through permitting and financing. Lundin has established a new royalty company to provide financial support to the Lunahuasi and Los Helados copper projects on the Argentina-Chile border.

These projects remain at permitting and early development stages, not yet in production. For investors, this preserves optionality but demands timeline discipline: the gap between a credible pipeline and delivered tonnes is measured in years, not quarters.

What the RIGI regime means for capital allocation decisions

Argentina did not just build a project pipeline. It rewrote the rules of jurisdictional competition.

The Régimen de Incentivo para Grandes Inversiones (RIGI), launched in July 2024, offers 30-year tax, customs, and foreign-exchange stability for qualifying projects above US$200 million. The regime’s core terms are designed to address the specific risk that has historically made Argentina a difficult destination for long-dated mining capital:

• 30-year fiscal stability horizon
• Foreign-exchange convertibility and repatriation guarantees
• Customs duty stability for project imports
• Eligibility across mining, energy, and infrastructure sectors above US$200 million

The proof-of-concept moment arrived in May 2025.

Rio Tinto’s Rincón lithium project, valued at approximately US$2.5 billion, became the first major company approval under RIGI, demonstrating the regime functions at megaproject scale.

Posco’s Sal de Oro lithium expansion (approximately US$207 million) is RIGI-eligible and targeting construction start in 2026. Pampa Energía and MEGA received approval for a US$3 billion investment, illustrating the regime’s application beyond mining. Galan Lithium’s Hombre Muerto West is targeting first lithium chloride concentrate in the first half of 2026, representing RIGI-era momentum in lithium development.

Multilateral capital is aligning with the framework. An Inter-American Development Bank (IDB) loan of US$100 million has reportedly been directed into a US$2.5 billion Argentine lithium project, suggesting institutional confidence in the regime’s durability.

The EXIM Bank financing restoration for Argentine mining and energy projects is a concrete signal that U.S. export credit agencies now view the RIGI framework as sufficient collateral for sovereign-level risk, a reassessment that materially lowers the cost of equipment and project finance for qualifying developments.

The competitive pressure is real. Chile, Peru, and Ecuador now face a jurisdiction that offers long-dated fiscal certainty their own frameworks do not match. For investors evaluating jurisdictional weighting across the Andean belt, RIGI’s operational track record warrants a material reassessment of Argentina’s risk-adjusted returns.

Argentina’s official RIGI framework outlines the adhesion process, eligibility criteria, and the specific fiscal, customs, and foreign-exchange guarantees available to qualifying projects, providing investors with the primary regulatory reference for assessing the regime’s enforceability and scope.

Chile and Peru: established producers navigating execution complexity

Chile: production pipeline vs. structural headwinds

Chile’s copper pipeline remains the largest in the region. Approximately 31 copper projects sit in the national portfolio, with 13 projects worth US$14.8 billion advancing in 2026. Seven of those are targeting operational startup, adding approximately 500 kt/y of capacity backed by US$7.1 billion in investment. Six further projects (approximately US$7.7 billion) are expected to begin construction. Santo Domingo, operated by Capstone Copper, is among the key projects targeting a 2026 construction start.

The headline numbers, however, obscure real constraints. Several mature operations face declining grades, water access limitations, and permitting complexity that cap how fast Chile can grow output. The cost per incremental tonne is rising.

Chile’s lithium governance is shifting toward state-led models. The Codelco-SQM Atacama joint venture has secured a multi-million-tonne quota approved to 2060. The ENAMI-Rio Tinto Salares Altoandinos partnership targets approximately 75,000 t/y of lithium carbonate equivalent (LCE) from the early 2030s. Both face intense scrutiny over water use and Indigenous rights, particularly in areas such as Maricunga, and investors should factor these dynamics into timeline assumptions.

Teck Resources is reportedly preparing a combination with Anglo American, which could reshape ownership of significant Chilean copper assets and affect near-term supply trajectories.

Chile’s pipeline calculus now includes a strategic bilateral dimension: South Korean offtake alignment secured through the Santiago critical minerals agreement gives Chilean copper and lithium producers a direct channel to one of Asia’s largest battery and electronics manufacturing bases, partially offsetting the grade and water constraints that limit pure volume growth.

Peru: geological upside held back by social-licence deficits

Peru’s mining project portfolio is valued at approximately US$64 billion, with roughly 27 copper projects worth an estimated US$38.5 billion scheduled for development through 2031. The geological upside is among the strongest in the world.

The binding constraint is not ore grades. Social conflict, community opposition, and political instability have repeatedly moved projects from “planned” to “delayed” status. Buenaventura’s San Gabriel mine, which commenced sales, stands as a successful execution example, but it remains more exception than pattern.

Best-in-class operators treating community relations as a core capability, not a compliance function, is now a differentiating factor that directly affects schedule, capital expenditure, and project returns.

The forces that will determine which projects actually get built

Geology is no longer the limiting variable across the Andean belt. The forces that will separate delivered projects from stalled ones cut across all four jurisdictions, and investors should weight them as heavily as ore grades and capital costs.

1. Social licence and environmental constraints: Water use and Indigenous rights scrutiny in Chilean salars (Maricunga specifically), community opposition to Ecuador’s Loma Larga, and Peru’s broader pattern of social conflict have each delayed or reshaped major projects. The constraint is structural, not episodic.
2. Policy competition: Argentina’s RIGI has raised the bar for fiscal stability across the region. Chile, Peru, and Ecuador face increasing pressure to respond with their own framework improvements or risk losing capital to a jurisdiction that now offers 30-year certainty. The US USMCA legislative review introduces an additional policy variable with potential supply-chain implications.
3. Western supply-chain alignment: US DFC, IDB, and EU Global Gateway financing are increasingly shaping which projects reach final investment decision and on what terms. A proposed US$465 million US DFC financing for Serra Verde rare earths in Brazil illustrates how Western capital alignment is becoming a structuring force beyond lithium and copper.

The geopolitical dimension of Argentina’s investment attractiveness extends beyond RIGI: the ARTI framework governing U.S. access to Argentine minerals has introduced a new layer of bilateral supply-chain alignment that is increasingly shaping which projects attract Western institutional financing and on what preferential terms.

1. Technology integration: AI applications in Latin American mining are already reported as generating measurable financial benefits.

AI-assisted planning, predictive maintenance, and process optimisation are already delivering million-dollar cost and productivity gains across regional mining operations, making technology integration capability a material differentiator in project economics.

Projects with institutional backing, community consent frameworks, and Western offtake alignment carry a structural advantage in reaching final investment decision. Due diligence that stops at geology and capital costs is no longer sufficient.

The milestones investors should be watching through 2028

The gap between a compelling regional thesis and investable outcomes is execution at the project level. The following milestones function as bellwethers for the broader copper and lithium investment case across Latin America.

RIGI uptake volume deserves particular attention. The number of additional large mining projects formally entering Argentina’s regime following the Rio Tinto Rincón and Pampa Energía precedents will indicate whether the framework is a durable competitive advantage or a single-cycle policy experiment.

Chile’s 2026 copper construction starts and the Warintza construction decision are the most time-sensitive signals in the near-term pipeline. If both advance on schedule, they confirm that the Andean belt can convert geological promise into physical infrastructure within this investment cycle.

Latin America’s copper and lithium window is open, but execution is the variable

The demand imperative for copper and lithium is not discretionary. Electrification, grid buildout, and battery supply chains require volumes that existing global production cannot deliver, and Latin America’s geological endowment is unmatched.

The competitive differentiation across jurisdictions is now clearly drawn. Argentina’s RIGI positions it as the policy innovation leader offering long-dated fiscal certainty. Chile remains the volume incumbent, but with emerging grade, water, and governance constraints that cap growth rates. Ecuador is the optionality play, with Warintza’s Tier-1 reserve base offering exposure to new supply not yet priced into market expectations. Peru offers the highest geological upside paired with the highest social-licence risk.

Western strategic autonomy investment in copper and lithium supply chains is not limited to U.S. initiatives: European and Canadian capital is now flowing into Andean projects specifically to reduce dependence on Chinese processing capacity, and the EU Global Gateway commitments referenced in project financing term sheets reflect a coordinated supply-chain diversification strategy with direct implications for which Latin American developers attract offtake at a premium.

The 2026-2028 construction start window is when this pipeline separates into projects that deliver and projects that stall. Current positioning decisions carry weight precisely because the window is finite: the copper deficit is not waiting for permits, community consultations, or policy certainty to arrive.

Investors monitoring the specific project milestones identified above, from Warintza’s construction decision to RIGI uptake volume to Chile’s copper startup cohort, hold the most direct signals of whether Latin America’s copper and lithium boom delivers on its structural promise.
