Brazil Leaps to 2,000 Tonnes: Rare Earths Production Triples in 2025

In a single year, Brazilian rare-earth mine production jumped from 560

tonnes of rare-earth-oxide equivalent to an estimated 2,000 tonnes,

according to the U.S. Geological Survey's 2026 Mineral Commodity

Summaries. The country that was a rounding error in the global

rare-earth supply table two years ago is now a credible mid-tier

producer — and climbing fast.¹²

The 2025 Numbers

The USGS Mineral Commodity Summaries 2026 reports Brazilian rare-earth

mine production at 560 tonnes REO in 2024 and 2,000 tonnes in 2025, a

257 percent year-on-year increase.¹ No other major producer in the world

grew at anything close to that pace during the same period. Australia

held flat at 29,000 tonnes; the United States climbed from 45,500 to

51,000 tonnes; China's reported output was unchanged at 270,000 tonnes.

The absolute tonnage is still modest — Brazil contributed roughly 0.5

percent of the estimated 390,000 tonnes of global 2025 production — but

the rate of change tells a different story.¹ A producer that triples

output in a year is signalling that a specific project is scaling

quickly. In Brazil's case, the project is Serra Verde's Pela Ema

operation in Goiás.

Serra Verde as the Anchor

Serra Verde entered commercial production in early 2024 and has been

ramping since. The company's stated plan is to reach 6,500 tonnes of

rare-earth oxides per year by the end of 2027, over a 25-year mine

life.² If that target is hit, Serra Verde alone would account for

roughly 1.7 percent of global rare-earth supply — a significant share

for a single operation.

The economics are supported by the deposit type. Pela Ema is an

ionic-adsorption clay — the same style that has made southern China

dominant in heavy-rare-earth supply for decades. Ionic clays are cheaper

to process than the bastnaesite or monazite sources that dominate

elsewhere, and they carry a meaningful share of the high-value heavy

rare earths (dysprosium, terbium) that the permanent-magnet industry

needs most.

The ramp has not been without challenges. Serra Verde operates in a

country where rare-earth processing expertise has historically been

limited, and the company has had to build out the technical capability

as it scales. The 2024-2025 output trajectory suggests the learning

curve is being navigated successfully.

The commercial model is also novel for Brazil. Serra Verde sells mixed

rare-earth concentrate into the international market, primarily to

Chinese and emerging European separators. As the Viridis-Ionic refining

hub in Poços de Caldas comes online, a share of that concentrate could

be processed domestically, capturing midstream value that currently

flows overseas. That pathway is the most important second-stage

development for the Brazilian industry as a whole.

Why Ionic-Clay Geology Matters

The dominant rare-earth deposits in the industrialised world today are

bastnaesite-bearing carbonatites (Mountain Pass in California, Mt Weld

in Australia) and monazite from heavy-mineral sands (in several

jurisdictions). Ionic-adsorption clays are structurally different. They

form in the weathering profile above granitic rocks in tropical climates

and concentrate rare earths by adsorption onto clay minerals.

The practical advantage is that the rare earths can be extracted with

mild leaching chemistries rather than the high-temperature cracking

processes that bastnaesite or monazite require. Capital intensity is

lower, operating costs are lower, and environmental footprint is

generally smaller. The disadvantage is that ionic clays typically have

lower total rare-earth content per tonne — the economics rely on scale

and process efficiency rather than grade.

Brazil has large tracts of Amazonian and central-Brazilian terrain with

the right geological conditions for ionic-clay formation. Serra Verde is

the first such deposit at commercial scale, but Aclara Resources at its

Carina project in Goiás and Meteoric Resources at Caldeira in Minas

Gerais are working similar clay-hosted systems. All three projects

benefit from the same technical advantages.

US Capital Validation

The 2025 Brazilian rare-earth story came with external financial

validation. In November 2025, the U.S. International Development Finance

Corporation (DFC) announced up to US$465 million in financing for Serra

Verde, to support upgrades at Pela Ema, cover operational expenses and

refinance existing shareholder debt.² The announcement came in the

context of a broader U.S.-Brazil alignment on critical minerals — and it

signalled that Washington sees Brazilian rare-earth production as

strategically important.

The validation extended to Aclara, which secured a US$5 million DFC

financing package in September 2025 and submitted its Environmental

Impact Assessment for the Carina project in May. Aclara is targeting

commercial production in 2028.² Taken together, the DFC activity in 2025

amounts to the largest external capital commitment ever made to

Brazilian rare earths.

The Bigger Country Ranking

The USGS's 2026 report also emphasises Brazil's reserve position.

Brazilian rare-earth reserves are estimated at 21 million tonnes REO —

the third-largest reserve base in the world, behind only China (44

million tonnes) and Australia (36.3 million tonnes, or 3.3 million

tonnes on a JORC-equivalent basis).¹ That puts Brazil ahead of Vietnam

(3.5 million tonnes), Russia (3.8 million tonnes) and every other

potential supplier outside the top two.

The reserve ranking matters for long-run strategic planning. At current

global consumption rates, Brazil alone could supply the world for

decades if the processing and downstream infrastructure were in place.

The production side has begun moving; the midstream and downstream story

— Viridis Mining and Minerals' joint venture with Ionic Rare Earths in

Poços de Caldas — is the next chapter.

Outlook

Brazil's rare-earth production is on track to continue growing quickly

through 2026 and 2027. Serra Verde's ramp toward 6,500 tonnes per year,

Aclara's move toward 2028 first production at Carina, and Meteoric's

progression of Caldeira through feasibility together suggest that the

2025 leap to 2,000 tonnes will be followed by another step-change in

2026-2027. Whether Brazil can reach 10,000 tonnes per year by the end of

the decade depends on execution at multiple operators simultaneously,

but the trajectory is established. For a country that had no meaningful

rare-earth production five years ago, the 2025 number is not an

end-point — it is a foundation, and the first of several milestones that

the Brazilian rare-earth industry is expected to set as Serra Verde,

Aclara and Meteoric move through their respective ramp and commissioning

schedules over the next 24-36 months against a firm price environment.

2025 — up 257% year-on-year. Serra Verde's ramp, the US DFC deal, and
