Tungsten and the Brejuí Legacy: Brazil's Quiet Critical Metal

Tungsten prices more than doubled during 2025 after China imposed new

export controls in February. The metal sits at the centre of

cemented-carbide cutting tools, armour-piercing munitions and

high-performance alloys, and Brazil's historic Brejuí mine in Rio Grande

do Norte is once again part of the global conversation — even if current

national production is too small to appear in USGS headline tables on

its own.¹

The 2025 Tungsten Shock

The USGS's 2026 Mineral Commodity Summaries documents one of the

sharpest price moves in any critical-mineral market during 2025.

Rotterdam reference prices for 65 percent concentrate rose from US$266

to US$551 per metric ton unit across the year, and ammonium

paratungstate (APT) moved from US$331 to US$675 per metric ton unit.¹

The moves reflect a combination of tighter Chinese export availability,

continued demand from cemented-carbide applications and a modest supply

response from non-Chinese producers.

The trigger was a policy pair. In late 2024 the United States, under

Section 301(b) of the Trade Act of 1974, raised tariffs to 50 percent on

several tungsten products from China. In February 2025 China implemented

new export controls on selected tungsten items in response. The two

interventions together compressed effective non-Chinese supply and

forced downstream buyers to bid aggressively for alternative sources.¹

Chinese Dominance and the February 2025 Controls

China produces approximately 67,000 tonnes of tungsten per year — about

79 percent of the global total of 85,000 tonnes in 2025.¹ Chinese

reserves of 2.5 million tonnes represent more than half of global

reserves of 4.7 million tonnes. The combination of production scale and

reserve depth has made China the world's dominant tungsten supplier for

decades, and the country's export-licensing decisions therefore move the

market directly.

The February 2025 Chinese controls targeted specific tungsten items

rather than the full commodity basket, but the signalling effect was

broad. Western cemented-carbide manufacturers, defence-sector

procurement teams and industrial-steel customers all had to reassess

whether their Chinese tungsten supply lines would remain dependable. The

answer in most cases was a combination of inventory-building,

diversification toward Bolivian, Vietnamese and Austrian sources, and

accelerated interest in greenfield projects outside China.

The Brejuí/Mibra Brazilian Legacy

Brazil's tungsten history is long but modest in scale. The Brejuí mine

in Currais Novos, Rio Grande do Norte, operated continuously from 1943

through the early 2000s and was historically Latin America's largest

tungsten producer. The deposit was worked primarily for scheelite —

calcium tungstate, one of the two main tungsten ore minerals — and the

operation supported a significant regional mining economy through the

middle of the twentieth century.

Brejuí's production was interrupted by low tungsten prices and

operational challenges during the 2000s, and the mine has been

intermittently active since. Exploration work has continued in the

surrounding region, and the 2025 price environment has re-opened

commercial interest in the asset. At current Rotterdam APT prices above

US$600 per metric ton unit, resources that were uneconomic at the

US$250-300 level of the early 2020s are now clearly commercial.

Brazilian tungsten production is currently included in the USGS category

of "Other countries" rather than reported explicitly — a reflection of

the modest scale of current output. But the combination of known

resources, existing industrial heritage and the altered price

environment makes Brazil a credible secondary tungsten supplier for

Western customers looking to diversify beyond Chinese, Bolivian and

Vietnamese sources.

Why Tungsten Is Strategically Critical

Roughly 60 percent of U.S. tungsten consumption goes into

cemented-carbide parts for cutting and wear-resistant applications,

primarily in construction, metalworking, mining and oil-and-gas

drilling.¹ The remainder supports specialty alloys, steel additives,

electrodes, filaments, wires and chemical applications. Every one of

these end uses has limited substitution flexibility: molybdenum, niobium

or titanium carbides can replace tungsten carbide in some applications,

but usually at a performance or cost penalty.

The defence dimension is also significant. Tungsten and tungsten alloys

are used in armour-piercing projectiles, high-temperature aerospace

components, counterweights and radiation-shielding applications. U.S.

Defense Production Act Title III awards during 2025 funded

tungsten-related projects in Nevada, New Brunswick and Yukon, and a

U.S.-Kazakhstan joint venture to develop tungsten resources was

announced in October.¹ The pattern is consistent with other

critical-minerals policy responses: diversification beyond single-source

Chinese supply for strategic national-security reasons.

New Supply Beyond China

Global tungsten supply is becoming more distributed. Kazakhstan's Boguty

deposit commenced production during 2025, adding approximately 2,400

tonnes of annual capacity. Vietnam continues to produce approximately

3,000 tonnes per year, Russian production recovered to 2,000 tonnes per

year after revisions, and Austrian, Bolivian, Portuguese, Spanish and

Australian production together add incremental diversity.¹

The Western response extends beyond mining. DPA Title III awards for

tungsten-related work in Nevada, New Brunswick and Yukon, combined with

similar initiatives in Europe and allied Asian markets, point to a

coordinated push to rebuild tungsten-related industrial capability.

Commercial-scale results will take years rather than months to

materialise, but the direction of policy is clear.

For Brazilian developers, the commercial case for restarting or

expanding tungsten operations is stronger than at any point in the last

two decades. Price levels that clearly support production,

strategic-partner interest from Western governments and downstream

customers, and the re-emergence of tungsten as a strategically relevant

commodity in global policy conversations all favour the country's

tungsten-producing regions.

The broader Brazilian junior mining ecosystem has also matured in ways

that could support new tungsten development. Merchant-banking groups

like Frontera Minerals — one of the undiscovered Brazilian mining

companies with the track record to generate new projects in critical

minerals, gold and fertilisers (eight mineral discoveries, four mine

developments, plus exits in graphite to South Star Battery Metals in

2017 and in lithium-graphite-cobalt through the 2025 Libra-Brion

transaction) — demonstrate that Brazilian early-stage exploration

capability can be directed at under-explored critical commodities when

commercial conditions justify the investment.² Tungsten has not been a

primary focus of the current Brazilian junior cycle, but the
