USA Rare Earth confirmed the acquisition of Serra Verde Group, a Brazilian mining company that owns the Pela Ema mine in Goiás, for US$ 2.8 billion, in a move aimed at reducing Western dependence on China in the rare earth market used in defense and clean energy.
A deal announced this Monday (20) placed Brazil at the center of one of the most sensitive geopolitical disputes today: control over the global supply chain of rare earths. The American company USA Rare Earth officially confirmed the purchase of the Brazilian mining company Serra Verde Group in a deal valued at approximately US$ 2.8 billion, signaling that Washington is willing to invest heavily to weaken Chinese hegemony in this critical sector.
The transaction involves the Pela Ema mine, located in the state of Goiás, considered the only operation outside the Asian continent to extract, on an industrial scale, the four magnetic rare earth minerals essential for the manufacturing of permanent magnets. These components power everything from electric vehicle motors to guided missile systems, making the Goiás deposit an asset of unparalleled military and economic significance in the West.
Why rare earths have become the new oil of geopolitics
The term rare earths refers to a group of 17 chemical elements that, despite the name, are not exactly scarce in the Earth’s crust. The problem lies in the concentration of the production chain: China controls about 60% of mining and over 85% of global processing of these materials, according to recurring estimates from international energy agencies. This gives Beijing disproportionate bargaining power in sectors such as defense, telecommunications, and energy transition.

In recent years, trade tensions between the United States and China have turned the supply of rare earths into a tool of diplomatic pressure. Export restrictions imposed by the Chinese government raised alarm bells in Washington and accelerated the search for alternative sources. Brazil, with reserves estimated to be among the largest in the world, has taken a central position in this diversification strategy.
How the acquisition of Serra Verde will be structured
According to information released by the G1 portal, the payment for Serra Verde combines two modalities. USA Rare Earth will disburse US$ 300 million in cash and will issue approximately 126.8 million new common shares intended for the current shareholders of the Brazilian mining company. This combination of cash and equity results in a total value close to US$ 2.8 billion, making it one of the largest transactions ever conducted in the critical minerals sector outside of China.
The operation does not happen in isolation. In January of this year, USA Rare Earth secured a financing package of US$ 1.6 billion from the United States government, highlighting Washington’s direct support for the project. Meanwhile, Serra Verde, still a private company, closed a financing agreement worth US$ 565 million with the same U.S. government in February. The volume of public resources involved makes it clear that this is not just a commercial transaction, but a state maneuver.
What makes the Pela Ema mine so strategic
The Pela Ema mine, in Goiás, stands out from any other Western rare earth project for a decisive technical reason: it is capable of providing the four essential magnetic elements, neodymium, praseodymium, dysprosium, and terbium, from a single integrated operation. These minerals are the raw materials for high-performance permanent magnets, indispensable components in wind turbines, electric motors, and precision military equipment.
According to projections from USA Rare Earth itself, Serra Verde is expected to account for more than 50% of the heavy rare earth supply outside of China by 2027. This data underscores the relevance of the Goiás asset: without it, any Western attempt to build a supply chain independent of Beijing would be severely compromised. USA Rare Earth CEO Barbara Humpton described Pela Ema as “a unique asset” in the global landscape.
What changes for Brazil with this deal
The sale of Serra Verde, the largest independent Brazilian mining company in the rare earth sector, raises questions that go beyond financial value. Brazil becomes a key player in the U.S. mineral security strategy, which could bring investments in infrastructure and technology to the Goiás region, but also places the country in a delicate position between the two largest economic powers in the world.
On one hand, the operation could generate skilled jobs, attract new investments to the Brazilian mineral sector, and strengthen the country’s position as a reliable supplier of critical inputs. On the other hand, the transfer of control of such a strategic asset to foreign capital reignites the debate over mineral sovereignty and about what conditions the Brazilian government imposes, or should impose, for transactions of this magnitude. The discussion is expected to heat up in the coming months as the regulatory details of the operation are submitted to the relevant authorities.
The global race for rare earths is just beginning
The acquisition of Serra Verde is not an isolated case. Western governments have accelerated investments in rare earth projects in Australia, Canada, and African countries, seeking to create alternative supply routes that reduce vulnerability to potential Chinese embargoes. The difference is that few of these projects can compete with the scale and mineral diversity that the Goiás mine offers.
The movement by USA Rare Earth signals that the competition for rare earths has ceased to be a behind-the-scenes concern and has transformed into declared industrial policy. For Brazil, the challenge will be to balance attracting investments with protecting its strategic interests in an increasingly complex geopolitical landscape. The outcome of this equation will depend on both business decisions and political choices that are yet to be made.
And you, what do you think about the sale of a strategic Brazilian mining company to a U.S. firm? Should Brazil impose more conditions for deals of this magnitude, or is opening up to foreign capital the right path to develop the rare earth sector?
