Brazilian Landowner Battles Mining Giant Over Fair Compensation for Rare Earth Extraction

Landowner and family lost property access and livelihood for 8+ years; farm suffered irreversible environmental degradation from unauthorized mining operations.
A single citizen cannot be heard against a mining company's power
Rios reflects on his eight-year struggle to secure fair compensation for mineral extraction on his farm.

Landowner Daniel Rios lost access to his farm after Serra Verde obtained judicial possession in 2018, receiving only monthly payments he considers unjust for a $2.8 billion mineral operation. The company used mining rights as collateral for $115M and $565M loans, revealing a vast gap between offered compensation and actual property value, according to the family's mining law specialist.

A Brazilian farmer has waged an 8-year legal battle against Serra Verde mining company over inadequate compensation for rare earth mineral extraction on his Goiás property, now complicated by the company's $2.8 billion sale to a U.S. firm.

Daniel Rios lost access to his own farm in 2013. That's when Serra Verde, a mining company, arrived in Minaçu, a municipality in Goiás state, with interest in extracting rare earth minerals—elements now at the center of a global economic race. After three years of exploration on his land, the company offered him a deal: monthly payments of four thousand reais and a one-time compensation of roughly sixty-five thousand dollars. Rios refused. The land had become valuable precisely because of what lay beneath it, and the offer felt like a fraction of what it was worth.

In 2018, Serra Verde went to court. They won the right to occupy the property. What followed was eight years of legal limbo during which Rios could enter his own farm only once a month, and only with judicial permission. The company remained, extracting minerals worth billions while the question of fair compensation dragged through the courts unresolved.

The structure of Brazilian mining law created this trap. The Constitution says minerals belong to the state, not the landowner. A mining company can extract them if it has the right permits and pays rent, compensation, and royalties to the surface owner. In theory, this protects the national interest. In practice, as Rios's case shows, it can leave a farmer powerless while a corporation profits from his land.

Rios's lawyer, Daniel Cavalcante, a specialist in mining law, uncovered a telling detail. Serra Verde had used the mining rights on Rios's property as collateral to borrow one hundred fifteen million dollars in 2018, and five hundred sixty-five million dollars in 2024. The gap between these figures and what the company offered Rios was staggering. A court eventually ordered compensation of three million reais—roughly six hundred thousand dollars at current exchange rates. Cavalcante argued the figure was absurdly low. Even the municipal tax assessor had valued the land higher than the court-appointed experts, who happened to be agronomists, not mining specialists, evaluating a billion-dollar mineral operation.

The environmental cost added another layer of injustice. Over one hundred fifty thousand tons of ore sat piled on Rios's property, extracted during years when Serra Verde held only exploration permits, not mining licenses. The land bore scars—moved earth, altered water systems, degradation that Rios said was in many places irreversible. He had no guarantee the company would restore it. Serra Verde operated through subcontractors and leasing arrangements, a structure that made accountability murky. If the company walked away tomorrow, who would clean up the mess?

Then, in April 2024, Serra Verde sold itself to USA Rare Earth, an American firm, for two point eight billion dollars. The sale happened without waiting for the Brazilian courts to finish deciding Rios's case. Cavalcante filed a new lawsuit seeking to block the transaction until the original dispute was resolved. His argument went beyond Rios's individual claim. He framed it as a constitutional question: Who decides what happens to Brazil's mineral wealth? According to the Constitution, the answer should be the Brazilian state, in the national interest, after hearing from those affected. None of that had happened.

The case has become a test of how Brazil will handle critical minerals in the coming decades. Rare earth elements power everything from smartphones to weapons systems. Control over their supply is now a matter of geopolitical strategy. The way this dispute is resolved—whether Rios gets fair compensation, whether the sale to an American company proceeds, whether environmental damage is addressed—will signal how seriously Brazil takes its own sovereignty over these resources. For Rios, it is also simply about being heard. "A single citizen alone cannot be heard against the economic power of a large mining company," he said. Now, finally, people were listening.

I practically lost access to my own property. I was removed by court order while the company remained, paying amounts I consider unjust and incompatible with the reality of the operation.
— Daniel Rios, landowner
This is not a fight between a family and a company, but a discussion about who decides what happens with Brazil's subsurface. That answer, in our constitutional system, is the Brazilian state, in the national interest, after hearing from those affected. None of that happened here.

Why did Rios reject the initial offer if it meant losing access to his land anyway?

Model

Because he understood what the company knew—that the minerals underneath made the property far more valuable than the payment reflected. Once Serra Verde found rare earths there, the land's worth changed fundamentally. Accepting would have meant surrendering that value for a pittance.

Inventor

But Brazilian law says minerals belong to the state, not the landowner. So how does Rios have any claim at all?

Model

He has a claim to compensation for the use of his surface—the land itself. The state owns what's below, but the company still has to pay him for occupying and degrading his property. The law is clear on this. What's unclear is what "fair" compensation actually means when a billion-dollar operation is involved.

Inventor

The company used the mining rights as collateral for half a billion dollars. Why does that matter legally?

Model

It proves the property was worth vastly more than what Serra Verde offered Rios. If the company could pledge those rights for five hundred sixty-five million dollars to a lender, then claiming the surface owner deserves only three million reais is obviously dishonest. The numbers don't align.

Inventor

What happens to the environmental damage if the American company abandons the site?

Model

That's the nightmare scenario nobody has answered. Serra Verde operates through contractors and leases. If USA Rare Earth decides to exit, there's no clear mechanism forcing anyone to restore the land. Rios could be left with a degraded property and no recourse.

Inventor

Is this just about one farmer, or is something larger at stake?

Model

It's about sovereignty. Rare earth minerals are strategic resources now. The question is whether Brazil controls what happens to them or whether foreign companies can extract them, profit enormously, and leave. The court's answer will shape how Brazil negotiates these deals in the future.
