Uranium Sleeping Giant: Caetité, Santa Quitéria and Brazil's Nuclear Pipeline

Brazil holds among the world's largest uranium reserves but produces

almost none. Indústrias Nucleares do Brasil's Caetité operation is

currently inactive, Santa Quitéria in Ceará is in licensing, and the

country's two operating nuclear reactors rely primarily on imported

fuel. The gap between reserve position and current production makes

Brazilian uranium one of the most unusual critical-mineral stories on

the continent.¹

The Reserve Paradox

Brazil's uranium reserves rank among the five largest in the world,

estimated at several hundred thousand tonnes of contained uranium at

multiple deposits.¹ Top global producers — Kazakhstan, Canada,

Australia, Namibia, Uzbekistan and Russia — collectively supply roughly

50,000-55,000 tonnes of U3O8 per year, meeting the bulk of global

nuclear-power demand.

Brazilian production sits at essentially zero. The INB Caetité mine in

Bahia, historically the country's sole operating uranium mine, has been

idle in recent years. The Santa Quitéria project in Ceará, which would

combine uranium production with phosphate fertiliser output, has been in

the Brazilian federal permitting process for over a decade. The contrast

between reserve strength and production weakness is stark, and the

reasons are political and administrative rather than geological or

economic.

Caetité and the INB Monopoly

Brazilian uranium policy gives Indústrias Nucleares do Brasil (INB), a

state-owned enterprise, a legal monopoly on uranium mining, processing

and enrichment. That monopoly, established in the Brazilian constitution

and elaborated in specific federal legislation, means that private

investment in Brazilian uranium is impossible under current law — and

the entire commercial path for uranium development depends on INB's

capacity and willingness to invest.

INB's capacity has been limited for decades. The Caetité mine operated

at modest scale through much of the 2000s and 2010s but has since been

idle, reflecting a combination of technical challenges, investment

constraints and political attention that has consistently been

elsewhere. Resumption of Caetité production has been announced multiple

times but has not yet been achieved at commercial scale.

The monopoly arrangement has been debated in Brazilian policy circles

for years. Proposals to allow private or foreign participation in

Brazilian uranium — subject to regulatory oversight and

national-security constraints — have been floated multiple times but

have never advanced to legislation. The political economy of changing

the framework is complicated by the sensitivity of nuclear material and

by the institutional role INB plays in the country's broader energy and

defence establishment.

Santa Quitéria

The Santa Quitéria project in Ceará is the most advanced

development-stage uranium opportunity in Brazil. The project is

structured as a joint venture between INB and a private

phosphate-fertiliser producer, with the commercial rationale being that

the ore carries both uranium and phosphate, and processing the two

together is more efficient than either alone.

Santa Quitéria has been in environmental permitting for more than a

decade. The project has advanced through multiple licensing phases but

has not yet received the final licences required for construction. When

it does commission, it could produce several thousand tonnes of U3O8 per

year — meaningful for Brazil, though still modest on the global scale.

The project is strategically important for Brazilian nuclear-fuel

self-sufficiency. Brazil's two operating reactors (Angra 1 and Angra 2,

with Angra 3 under construction) consume uranium in quantities that

Santa Quitéria could comfortably supply if it reaches commercial

production.

The Global Uranium Context

Global uranium demand is driven by nuclear-power generation. Current

operating capacity of approximately 395 GW consumes roughly 65,000

tonnes of U3O8 per year, with about 55,000 tonnes coming from primary

mine production and the rest from secondary sources such as

decommissioned weapons and civil stockpiles.¹

Demand is expected to grow meaningfully through the 2030s. Several

countries have announced new nuclear-build programmes, small modular

reactor projects are advancing commercially, and the energy-transition

discussion has increasingly included nuclear power as a zero-carbon

baseload option alongside renewables. International Atomic Energy Agency

and World Nuclear Association projections suggest demand could reach

70,000-80,000 tonnes per year by 2030.

Prices have responded accordingly. Uranium spot prices reached levels

above US$100 per pound during 2024 and traded in the US$80-110 range

through 2025, substantially above the pricing environment that prevailed

through most of the 2010s. At those prices, Brazilian uranium projects

become progressively more attractive economically.

Brazilian Strategic Positioning

If the political economy of Brazilian uranium policy shifts — allowing

Santa Quitéria to commission, Caetité to resume operation, or private

participation to enter the sector — the country could contribute

meaningfully to global uranium supply within the 2028-2032 window. The

reserve base is sufficient to support production comparable to mid-sized

global producers like Namibia or Uzbekistan over multiple decades.

The connection to other critical minerals matters. Uranium is not on

most standard critical-minerals lists because nuclear fuel is treated

separately in national-security frameworks, but its strategic importance

is comparable. Building Brazilian uranium production would extend the

country's critical-minerals portfolio into nuclear-energy-transition

relevance, which no other Latin American producer can match.

There is also a geopolitical angle. Western nuclear operators have been

actively seeking alternatives to Russian and Kazakh uranium supply

following the 2022 Ukraine conflict and subsequent sanctions
