Vale's Nickel Pivot: 177,200 Tonnes and a New Furnace at Onça Puma

Vale produced 177,200 tonnes of nickel in 2025 and guided to

175,000-200,000 tonnes for 2026. The Onça Puma operation in Pará

commissioned a second furnace in September 2025, expanding nominal

nickel capacity by 60 percent. Brazil's nickel industry is moving from a

steady contributor to a strategically positioned supplier.¹²

Vale's 2025 Nickel Year

Vale Base Metals reported full-year 2025 nickel production of 177,200

tonnes — a material contribution to the global supply picture that the

USGS places at approximately 3.9 million tonnes.² The company's guidance

for 2026 was 175,000-200,000 tonnes, with the upper bound reflecting the

full commissioning of the new furnace capacity at Onça Puma.¹

The numerical performance is notable for its stability. Nickel prices

spent much of 2025 in the lower half of the recent trading range, partly

because Indonesian supply surged and partly because macro conditions

softened industrial demand. Several global operators responded by

slowing or shutting high-cost mines — Australian nickel production fell

54 percent year-on-year according to the USGS, and Philippine output

dropped 24 percent.² Vale's Brazilian operations held their output

steady through this environment, reflecting the comparative cost

position of the Carajás complex and its associated nickel assets.

Onça Puma's Second Furnace

The strategic centrepiece of Vale's 2025 nickel story was the

commissioning of a second furnace at Onça Puma, completed in September

2025. The expansion lifted the site's nominal capacity by 60 percent, to

approximately 40,000 tonnes of nickel per year.¹

Onça Puma is a ferronickel operation in Pará state that has been

producing since 2011. It processes lateritic ore through

pyrometallurgical smelting, producing ferronickel that is sold into

global stainless-steel and alloy markets. The second-furnace expansion

is operationally significant because it both raises the site's output

ceiling and provides redundancy — a single-furnace operation suffers

more from unplanned downtime than a dual-furnace one.

The timing of the expansion also matters strategically. As Indonesian

supply continues to ramp and Australian and Philippine supply contracts,

the relative importance of Brazilian nickel inside the global pipeline

has risen. Onça Puma's capacity addition, combined with Vale's other

Brazilian nickel operations, helps anchor a meaningful non-Indonesian,

non-Russian share of global nickel supply.

Where Brazilian Nickel Fits Globally

The USGS places Brazilian 2025 nickel production at approximately 70,000

tonnes on its aggregated national figure, ranking Brazil the fourth- or

fifth-largest global producer depending on methodology.² The country's

reserve position is stronger: approximately 16 million tonnes of

contained nickel, which ranks Brazil fourth globally after Indonesia (62

Mt), Australia (25 Mt including JORC adjustments) and Russia (8.3 Mt).²

Vale's direct production of 177,200 tonnes exceeds the USGS Brazilian

national figure because the company operates meaningful capacity outside

Brazil — Sudbury and Thompson in Canada, Long Harbour refining in

Newfoundland, and other Base Metals assets. The difference between the

two numbers reflects the integrated global footprint that Vale brings to

the sector rather than a methodology inconsistency.

Brazil's nickel producers include more than Vale. Anglo American

operates Barro Alto and Codemin in Goiás, Horizonte Minerals is

developing the Araguaia project in Pará, and several smaller operators

contribute incremental production. The combined Brazilian footprint is

more diverse than the Vale headline suggests, and several of the

non-Vale projects have growth potential.

Indonesia and the Competitive Landscape

No discussion of Brazilian nickel is complete without acknowledging the

Indonesian position. Indonesia produced 2.6 million tonnes of nickel in

2025 — more than 13 times Brazil's direct output — following a 13

percent increase driven by the continued ramp of new HPAL (high-pressure

acid leach) and smelting operations that process the country's laterite

resources.² Indonesian reserves sit at approximately 62 million tonnes,

dwarfing Brazilian holdings.

The competitive dynamic is meaningful but not simple. Indonesian supply

is dominated by Chinese-invested operations and is particularly focused

on class-2 nickel for stainless-steel use, with growing but still

limited class-1 nickel for battery applications. Brazilian nickel output

includes both class-1 and class-2 streams, and Vale's Canadian

refineries produce substantial class-1 material that is specifically

relevant to battery markets.

The 2025 Executive Order 14285 in the United States also changes the

medium-term dynamic. By calling for development of seabed mineral

deposits — including polymetallic nodules and ferromanganese crusts

containing nickel — the order opens a potential new supply leg. A USGS

2022 assessment estimated that seabed deposits globally contain

approximately 4.5 billion tonnes of nickel, though commercial extraction

remains years from reality.²

What Vale's Nickel Pivot Means

Vale's 2025 nickel performance and 2026 guidance signal a specific

strategic choice. The company is prioritising production stability and

capacity additions in its Brazilian operations at a time when many

global peers are slowing capital deployment. That choice reflects both

the strength of Vale's balance sheet and its view that nickel's

medium-term demand curve — driven by EV battery growth and

stainless-steel consumption — will reward producers who have capacity in

place when demand firms.

The Onça Puma expansion also supports a broader Brazilian

critical-minerals narrative. As Vale, CBMM, Sigma Lithium and the

emerging Brazilian rare-earth operators position simultaneously, the

country is building a critical-minerals portfolio whose breadth is

unmatched outside China. The Onça Puma commissioning is one piece of a

larger story.

Outlook

Vale's 2026 guidance of 175,000-200,000 tonnes of nickel will be tested

against the actual performance of the new Onça Puma furnace and against

the continuation of subdued price conditions. If the expansion runs

smoothly and prices recover as Indonesian supply growth moderates,

Vale's nickel segment could contribute disproportionately to group

earnings. If prices stay soft and Indonesian supply continues to expand,

the capacity addition may produce more tonnage than the market absorbs

comfortably. Either way, Brazilian nickel now sits in a stronger

strategic position than it has in a decade — supplied by a major with a

long-horizon perspective, supported by public policy that treats

critical minerals as strategic infrastructure for Western industrial

economies, and increasingly integrated into global battery-supply-chain

discussions that were previously dominated almost entirely by

Indonesian, Chinese and, to a lesser but still notable extent
