Brazil Mining 2026: Iron Ore Critical Minerals and Vale

RioTimes Evergreen Guide | Series: Latin America Investing

Brazil holds the world’s second-largest rare earth reserves, the largest iron ore export base, and fast-expanding battery-metal assets that Washington and Beijing are competing to secure — yet the sector must navigate China’s decelerating property cycle, a US tariff offensive, and the long regulatory shadow of two catastrophic dam failures.

Brazil mining in 2026 is a study in productive tension. The country holds the world’s second-largest rare earth reserves, the globe’s largest iron ore export base, and fast-expanding battery-metal assets that Washington and Beijing are actively competing to secure — yet the same sector is navigating China’s decelerating property cycle, a US tariff offensive that has reconfigured trade flows, and the long regulatory shadow of the Mariana and Brumadinho dam disasters. Understanding these forces is essential for any serious assessment of Brazilian resource investment today.

Brazil’s Mining Sector at a Glance

Brazil’s mining industry generated R$298.8 billion in revenue in 2025, a 10.3% increase year-on-year, with the sector’s mineral trade balance reaching US$37.6 billion — 55% of Brazil’s entire trade surplus — according to IBRAM. Iron ore accounted for 52.6% of that revenue despite a 2.2% price decline; gold surged 65% to R$39 billion and copper jumped 50% to R$30 billion. Brazil closed 2025 with record iron ore exports of 416.4 million tonnes — the first time annual shipments exceeded 400 million tonnes — with China taking 71.2% of the total.

The country’s commodity range is unusually broad: Brazil ranks first in niobium (holding nearly 90% of world reserves), second in rare earths and graphite, third in nickel, and sixth in lithium. IBRAM projects US$76.9 billion in sector investment over the 2026–2030 cycle, with critical and strategic minerals alone accounting for US$21.3 billion — a 15.2% increase from the prior projection, reflecting the energy-transition premium now attached to Brazil’s resource endowment.

Vale and Iron Ore — The Backbone

No single company defines Brazil mining like Vale. In 2025, the Rio de Janeiro-headquartered giant produced 336.1 million metric tonnes of iron ore, a 2.6% increase year-on-year and its highest output since 2018 — surpassing Rio Tinto’s Pilbara operations for the first time since the Brumadinho dam disaster in 2019, according to Reuters. The S11D project in Carajás, northern Brazil, set a record of 86 million tonnes in 2025 alone.

For 2026, Vale guides 335–345 million tonnes of iron ore and 30–34 million tonnes of pellets, with capex at US$5.4–5.7 billion — reduced from a prior forecast of US$6.5 billion — as the Capanema project ramps to full capacity by Q2 2026, according to Argus Media. Pricing remains the central pressure: Vale’s average iron ore fines fell to US$91.6 per tonne in 2025, and analysts at BMI and Bernstein forecast US$95–96 per tonne for 2026, with China’s depressed property sector and new Simandou supply from Guinea as the primary downward drivers, according to Investing.com. Offsetting factors include robust Chinese steel exports, Vale’s diversification toward India, and the quality premium of Carajás high-grade ore.

Vale is simultaneously expanding its base metals division. Copper production hit 382,000 tonnes in 2025, a 9.8% increase and the company’s highest since 2018, with 2026 guidance at 350,000–380,000 tonnes and a long-term target of 700,000 tonnes by 2035, according to Yahoo Finance. This deliberate pivot toward energy-transition metals offers Vale a partial hedge against China’s property-driven iron ore weakness.

Critical Minerals: Nickel, Copper, Lithium and Rare Earths

The global energy transition has transformed what counts as a strategic asset in Brazil mining, and the country’s endowment extends well beyond iron ore. Brazil is the world’s third-largest nickel producer, a position anchored primarily by Vale’s Onça Puma complex in Pará state — Brazil’s largest ferronickel operation. In September 2025, Vale Base Metals commissioned a second furnace at Onça Puma, expanding nominal capacity by 60% to 40,000 tonnes of nickel per year at a cost completed nearly 13% under initial budget estimates, according to Mining.com. Vale’s total nickel production reached 177,200 tonnes in 2025, with 2026 guidance set at 175,000–200,000 tonnes. The longer-term target is 210,000–250,000 tonnes by 2030.

In lithium, Sigma Lithium (TSXV/NASDAQ: SGML) operates a nameplate capacity of 270,000 tonnes of lithium oxide concentrate per year at its Grota do Cirilo site in Minas Gerais — the fifth-largest such complex globally. After a strategic restructuring, Sigma resumed mining in early 2026, transitioning to owner-operated mining with all-in sustaining costs near US$600 per tonne. Phase 2 construction, targeting 520,000 tonnes per year, has most civil works completed, according to the company.

The most geopolitically significant development is the US$565 million financing deal between the US International Development Finance Corporation (DFC) and Serra Verde, Brazil’s only operating rare earths producer and one of the few outside Asia. Finalized in February 2026, the package funds expansion at the Pela Ema mine in Goiás, targeting 6,500 metric tonnes of total rare earth oxides annually by 2027, according to The Rio Times. Priority offtake clauses guarantee American buyers access to supply; the US government also holds an option for a minority equity stake. Serra Verde has terminated its Chinese offtake agreements — expiring at end-2026 — pivoting to Western buyers. The mine’s heavy rare earths — dysprosium and terbium, essential for EV motors, wind turbines, and defense systems — are produced by almost no one outside China, which controls over 90% of global rare earths processing.

Potash is another emerging pillar. Brazil Potash’s Autazes project — developed through subsidiary Potássio do Brasil in Amazonas state — would become Brazil’s largest potash operation with initial annual production of up to 2.4 million short tonnes, potentially meeting around 20% of Brazil’s current potash demand. The estimated US$2.5 billion project has secured binding offtake agreements covering 91% of projected output across multiple contracts, and in 2025 completed vegetation management and site readiness at both the plant location and port terminal, according to Yahoo Finance. Construction financing remains the critical path item for 2026.

Regulatory Environment and ESG Pressures

No sector in Brazil mining operates free of the shadow cast by the Mariana and Brumadinho dam disasters. The November 2015 Mariana collapse — operated by Samarco, a joint venture between Vale and BHP — poured an estimated 40–50 million cubic metres of mining waste down the Doce River, killing 19 people and contaminating 600 kilometres of waterway. The 2019 Brumadinho failure killed 270 people. Both events triggered sweeping reforms to dam safety standards and permanently elevated tailings management as a board-level governance matter. In October 2024, Brazil’s government reached a R$170 billion (approximately US$30 billion) settlement with Samarco, Vale, and BHP for Doce River basin restoration — the largest such settlement in Brazilian history — while BHP and Vale separately proposed a US$1.4 billion settlement for UK litigants, according to Discovery Alert. Critics note that ten years on, the Doce River remains contaminated and communities in the basin report little material improvement.

Brazil’s Congress passed Bill 2159/2021 — the so-called “Devastation Bill” — in 2025, introducing self-licensing for projects classified as “small” or “medium” environmental impact, including the category that previously covered the Mariana and Brumadinho tailings facilities. President Lula vetoed 63 of its most damaging provisions in September 2025, blocking exemptions for mining from licensing requirements, according to ICLG.com; a fast-track “strategic projects” pathway survived. IBAMA remains the central bottleneck, with licensing delays of two to five years standard for large mining developments. Congress is separately debating Bill 2,780/2024 for a consolidated critical minerals framework, and a Supreme Court ruling in February 2026 opened the door — for the first time — to regulated mining inside indigenous territories, adding sovereignty complexity to any Amazon-area project.

Brazil’s consumption tax reform, taking effect in 2026, introduces a 1% Excise Tax on activities deemed harmful to the environment — expressly including iron ore extraction — according to the Chambers Global Practice Guide: Mining 2026. CFEM royalties on mineral sales remain at 1%–3.5% of gross revenue.

Investment Risks and Opportunities in 2026

The risk picture for Brazil mining in 2026 turns on three overlapping forces: US tariff escalation, China demand headwinds, and the country’s own regulatory transition. US trade policy delivered a significant shock in 2025 — a sequence of executive orders culminated in a 40% IEEPA tariff on non-exempt Brazilian imports from August 2025, according to FTI Consulting, with iron and steel already subject to a 25% Section 232 tariff from March 2025. For most Brazilian mining exporters the direct impact is limited — iron ore flows overwhelmingly to China, not the US — but tariff exposure is material for equipment and input costs where American suppliers are involved, and the broader trade tension has raised Brazil’s country-risk premium for international capital.

Gold has been the sector’s clearest standout. Kinross Gold’s Paracatu mine in Minas Gerais — one of the world’s largest open-pit gold operations — produced 601,000 ounces in 2025, with Kinross allocating US$235 million in capex to Paracatu in 2026, up from US$189 million in 2025, according to BNamericas. A technical report filed in March 2026 confirms 4.8 million ounces of reserves and mine life to 2034. AngloGold Ashanti divested its Mineração Serra Grande gold mine in Goiás to Aura Minerals in late 2025 for US$76 million, signaling ongoing consolidation among mid-tier Brazilian gold assets.

Critical minerals represent the medium-term thesis. The Serra Verde DFC financing template — US government capital unlocking rare earth supply chains — could benefit Brazil’s broader pipeline of at least 50 energy-transition mineral projects with planned investments exceeding US$18 billion, according to the Ministry of Mines and Energy. BNDES and the MME have launched a R$1 billion Strategic Minerals Equity Investment Fund (FIP), with Vale committing 25% alongside BNDES. Iron ore’s trajectory, meanwhile, remains under pressure from Simandou’s ramp-up and China’s structural property sector decline; Vale’s pricing is likely to stay in the US$90–100 per tonne range absent meaningful Chinese stimulus. The Lula government’s push to add domestic value to raw exports — processing incentives over raw ore shipments — adds a policy wildcard for foreign offtake structures.

The Road Ahead

Brazil enters the second half of the 2020s with more geological leverage than at any prior moment. The Serra Verde DFC deal demonstrates that geopolitical demand for Brazilian minerals can unlock financing unavailable to conventional commodity projects, and the Autazes potash project, Sigma Lithium’s Phase 2 expansion, and Vale’s copper pipeline each signal a structural diversification away from iron ore dependence.

Dam safety, environmental licensing, and indigenous land rights are not peripheral ESG concerns in Brazil mining — they are the operational risk framework within which every large project must be planned and financed. The Mariana and Brumadinho disasters demonstrated the cost of getting this wrong: human lives, years of lost production, and reputational damage restricting capital access sector-wide. Whether Brazil can simultaneously accelerate extraction of urgently needed transition minerals and build governance infrastructure that makes that extraction durable remains the central variable for any credible investment thesis on the country’s resource sector.
