Copper and the Carajás Complex: Vale's Underrated Chapter

Copper is the most industrially essential of the energy-transition

metals, and Vale's Carajás Mineral Province is one of the world's great

copper-gold districts. Sossego, Salobo and the broader complex make

Brazil a top-ten global copper producer — but the story is still

underrated inside the country's critical-minerals narrative.¹

Vale's Carajás Copper

Vale's Sossego mine began commercial copper-gold production in 2004 and

remains one of Brazil's largest single-site copper operations. Salobo,

commissioned in 2012 and expanded multiple times since, is even larger.

Together with the Alemão project and smaller satellite operations, the

Carajás copper complex produces on the order of 400,000 tonnes of copper

in concentrate per year — meaningful tonnage in a global market where

annual refined-copper demand is approximately 22-23 million tonnes.

The operational context matters. Both Sossego and Salobo are open-pit

porphyry-copper-gold deposits hosted in the southern Pará iron-ore

district. Vale's decades of iron-ore mining experience in the region

translates directly into copper-mining efficiency: shared

infrastructure, shared workforce, shared logistics through the Carajás

railway and port of Itaqui. That integration produces cost structures

that make Brazilian copper competitive against Chilean, Peruvian and

Congolese peers even in lower-price environments.

The gold co-product stream is commercially significant. Sossego

contributed 4.2 percent of Brazilian gold output in 2025 and Salobo 3.9

percent, together representing more than 8 percent of national gold

supply.² At 2025 gold prices, those co-product ounces added substantial

revenue to what would otherwise be treated as pure copper operations,

and analyst models now routinely incorporate gold credits when

evaluating Vale's Base Metals segment.

Global Copper Context

Chile remains the world's largest copper producer at approximately 5.3

million tonnes annually, followed by Peru at roughly 2.3 million tonnes,

the Democratic Republic of Congo at 2.5 million tonnes, China at 1.7

million tonnes, and the United States at approximately 1.1 million

tonnes. Brazilian production sits below these leaders but still places

the country firmly inside the global top ten.

Global copper demand is rising roughly 2-3 percent annually, driven by

electrification: electric vehicles use two to three times more copper

than internal combustion equivalents; wind and solar installations

require substantial copper per megawatt of capacity; data-centre

construction and grid expansion add further demand. The aggregate

picture is a commodity whose demand curve is accelerating just as

several major producing jurisdictions face ageing orebodies and

declining average grades.

That structural tightness supported copper prices through 2024-2025 even

as other commodities softened. LME copper traded in the US$8,500-10,000

per tonne range through most of 2025, meaningfully above the

US$5,000-6,500 range that prevailed through much of the 2010s.

Lundin and Ero — Brazil's Other Copper Producers

Vale is not Brazil's only copper producer. Lundin Mining operates the

Chapada copper-gold mine in Goiás, which has been producing since the

late 2000s and has undergone expansion through multiple operating

cycles. Ero Copper operates the MCSA complex in Bahia, covering multiple

underground operations that produce copper concentrate alongside modest

gold by-product.

The combined non-Vale Brazilian copper production is smaller than the

Carajás complex but commercially significant. Chapada and MCSA together

contribute another roughly 100,000 tonnes of copper per year, bringing

Brazilian total production above 500,000 tonnes annually. Additional

development-stage projects in Pará, Mato Grosso and other states could

add further capacity through the second half of the decade.

Lundin and Ero are listed companies whose Brazilian operations represent

substantial shares of each company's global portfolio. Brazilian copper

production is therefore exposed to international capital markets in ways

that purely domestic operators would not be. Their commercial discipline

around cost management, capital allocation and reserve replacement

provides useful benchmarks for the broader Brazilian sector.

Why Copper Is Central to Every Other Critical Mineral

Copper sits at the centre of the critical-minerals story for a reason

that rarely receives enough emphasis: every other energy-transition

technology depends on it. Electric vehicles need copper for motor

windings, wiring harnesses, busbars and charging infrastructure. Wind

turbines need copper for generator windings and grid cabling. Solar

installations need copper for inverters, wiring and grid

interconnection. Data centres need enormous volumes of copper for server

and power-distribution infrastructure.

The implication is that copper supply constraints can cascade into every

other critical-minerals story. If copper prices rise sharply because of

supply-demand imbalance, the full cost stack for electric vehicles, wind

turbines, solar arrays and data centres rises with them. Brazilian

copper capacity therefore matters not only as a commodity position but

as a bottleneck-mitigation resource for the entire energy transition.

The Brazilian Geological Survey's favourability map for copper-gold

deposits along the Carajás-Tapajós-Alta Floresta axis identified

substantial potential for additional porphyry-copper discoveries through

the remainder of the decade. If exploration delivers, the Brazilian

copper industry could expand meaningfully beyond the current base

level.³

The Price Environment

The 2025 copper-price environment was constructive for Brazilian

producers. LME copper averaged approximately US$9,200 per tonne during

the year, with year-end prices nudging above US$10,000 per tonne on

supply-side concerns. At those levels, Brazilian operations with

established cost structures near or below US$5,000 per tonne all-in

sustaining cost generated robust cash flow, providing capital for

reinvestment in expansion, near-mine exploration and brownfield

development.

For Vale specifically, strong 2025 copper economics combined with the

expanded gold-credit contribution from Sossego and Salobo to make the

Brazilian copper segment disproportionately profitable. That positive

contribution matters in the context of Vale's broader critical-minerals

strategy and supports the company's continued capital deployment in

Brazilian operations.

Outlook

Brazilian copper is better positioned than at any time in the last

decade. The combination of established production capacity, supportive

commodity prices, a geological pipeline with meaningful optionality, and

the gold-credit revenue stream creates a compelling set of fundamentals.

Copper's central role in every energy-transition technology means that

Brazilian copper capacity will continue to attract capital and strategic

interest regar
