Buying the Land Does Not Mean Controlling the Subsoil: Legal Risks in Areas with Mineral Potential

The acquisition of rural properties, industrial areas, farms, plots of land, large tracts, or assets with relevant economic potential requires an analysis that goes beyond the real estate registry, the price, and apparent possession.

In many cases, the buyer looks at the land, the location, the size of the area, its productive vocation, and the possibility of future use. But the buyer fails to observe an essential layer: the subsoil.

In Brazil, ownership of the land is not automatically confused with ownership of mineral resources. This distinction is fundamental.

Whoever buys the surface of an area does not necessarily acquire the right to economically exploit the minerals existing in that property. Mineral activity has its own legal regime, depends on government authorization, is subject to the National Mining Agency — ANM — and may involve third-party mining rights already affecting the area.

Therefore, in certain transactions, the correct question is not only:

“Who owns the property?”

But also:

“Are there any mining rights over this area?”

1. A regular registry does not eliminate mineral risk

The real estate registry is an essential document in any acquisition. It reveals ownership, encumbrances, annotations, registrations, transfers, guarantees, attachments, and relevant restrictions.

But it does not show everything.

The existence of mining rights, a research application, research authorization, mining concession, mineral availability, or an administrative proceeding before the ANM may not clearly appear in the property registry.

This means that an apparently regular registry may coexist with a complex mining reality.

The buyer, therefore, should not limit due diligence to the registry certificate, tax debts, and the seller’s personal certificates. When the area has mineral vocation, strategic location, history of exploration, relevant geological occurrence, or specific economic interest, it is essential to broaden the analysis.

2. Land and subsoil follow different legal logics

In traditional real estate law, ownership is usually analyzed based on the registry, possession, chain of title, neighboring boundaries, debts, and urban or environmental limitations.

In mining, the logic is different.

Mineral resources have their own legal discipline. Exploration depends on a mining title, administrative procedure, compliance with technical requirements, reports, deadlines, environmental licensing, and observance of specific rules.

Thus, one person may own the surface, while another may hold mining rights related to the research or exploitation of a specific mineral substance in that area.

This difference completely changes the reading of the transaction.

To the buyer, the property may appear to be free.

To the mining system, the area may already be linked to an interest, application, authorization, or proceeding filed by a third party.

3. The risk of buying an area without consulting the ANM

The absence of a mining consultation may generate relevant consequences.

The buyer may acquire a tract of land believing that they will have full freedom to develop a certain project, only to later discover that there is a mining proceeding overlapping the area.

There may also be conflict between the intended use of the surface and existing or future mining activity.

Imagine, for example, the acquisition of an area for the implementation of a condominium, subdivision, logistics warehouse, power plant, industrial expansion, long-term agricultural activity, or an environmentally sensitive project.

If there is mining interest over the area, the economic planning may be affected.

The issue is not only legal. It is also economic, operational, and strategic.

The value of the area, its liquidity, its future use, its attractiveness for financing, its licensing feasibility, and its contractual security may all be affected.

4. Mineral potential is not the same as mining rights

Another important point is to distinguish mineral potential from mining rights.

An area may have geological potential, signs of mineral occurrence, or a favorable regional history. This, by itself, does not mean that the owner may freely exploit the mineral.

On the other hand, an apparently ordinary area may be covered by a third party’s mining application, authorization, or proceeding.

For this reason, the analysis must separate three levels:

a) ownership of the real estate surface;b) the existence or absence of formal mining rights;c) the actual economic potential of the mineral substance.

Confusing these levels may generate unrealistic expectations, exaggerated valuation, contractual conflict, and future disputes.

5. The seller must declare what they know about the area

In well-structured transactions, the purchase and sale agreement must contain specific representations regarding the condition of the property.

When there is mineral potential, a history of extraction, news of applications, drilling, geological studies, the presence of interested third parties, or administrative proceedings, the matter must be expressly addressed.

The seller must declare, as applicable:

a) whether they are aware of mining proceedings affecting the area;b) whether they have already authorized third parties to conduct research, drilling, or exploration;c) whether they have received proposals from mining companies;d) whether there are contracts, assignments, options, leases, permissions, or commitments related to mineral exploration;e) whether there are environmental liabilities arising from prior extraction;f) whether there are accesses, easements, internal roads, or areas used by third parties.

These declarations do not replace the buyer’s due diligence, but they help organize responsibility, information, and risk.

6. The buyer also has a duty of due diligence

The buyer’s good faith does not eliminate the need for due diligence.

In higher-value transactions, especially those involving rural, industrial, logistics, environmental, or mineral-potential areas, the buyer is expected to perform a technical analysis proportional to the size of the transaction.

This includes, where applicable:

a) consultation of the property registry;b) analysis of the chain of title;c) tax and judicial certificates;d) environmental verification;e) analysis of georeferencing;f) consultation of administrative restrictions;g) consultation with the ANM;h) assessment of any overlap with mining titles or applications;i) analysis of the history of use of the area;j) physical inspection;k) verification of accesses, occupations, and interferences.

The purchase of a relevant area without this analysis may transfer to the buyer a risk that was not priced into the transaction.

7. Mining may affect the value of the property

The existence of mineral potential may increase or reduce the value of an area, depending on the case.

It may increase the value when the asset has organized documentation, regular mining rights, consistent technical studies, environmental feasibility, and a clear legal structure.

But it may reduce the value when there is conflict with third parties, environmental liability, uncertainty over title, lack of licensing, irregular exploration, unproven expectation, or dispute between surface and subsoil interests.

The risk arises precisely when the price is formed based on narrative rather than evidence.

In mineral matters, the promise of wealth is often seductive. But real value depends on technical, legal, environmental, and economic support.

Without this validation, mineral potential may be nothing more than a hypothesis.

8. Special attention to rural areas and large tracts of land

Rural areas deserve special attention.

Often, the negotiation is conducted as a simple purchase of a farm, rural property, plot, or area for patrimonial expansion. However, certain regions have a mining history, pending applications, or interest from specialized companies.

In addition to ordinary real estate analysis, it is prudent to verify:

a) whether there are active mining proceedings over the area;b) which mineral substance is related to the proceeding;c) who is the holder of the application or authorization;d) at what stage the proceeding currently stands;e) whether there are pending requirements;f) whether research or physical intervention has taken place on site;g) whether there is related environmental licensing;h) whether the owner has already entered into any instrument with a third party.

This reading prevents the purchase from being made blindly.

9. The relationship between the surface owner and the mining rights holder

When a third party holds mining rights over a given area, a sensitive relationship may arise between the surface owner and the holder of the mining proceeding.

This relationship may involve entry into the area, research, indemnities, agreements, easements, use of accesses, damages, environmental restoration, coexistence with agricultural or real estate activity, and limits of action.

This is not merely a theoretical issue.

In practice, the lack of organization of this relationship may generate possessory, environmental, indemnity, and contractual conflicts.

Therefore, before the acquisition, the buyer must know whether they are buying an area free of mining interferences or whether they will have to manage a legal and operational coexistence with a third party.

10. Contractual clauses are essential

When the area has mineral potential or risk of overlap, the contract must be more carefully drafted.

Some clauses may be relevant:

a) a specific declaration regarding the existence or non-existence of known mining proceedings;b) an obligation to deliver technical and administrative documents;c) responsibility for prior liabilities;d) provisions regarding past or current mineral exploration;e) treatment of any future indemnity;f) rules regarding third-party access;g) a condition precedent for completion of the purchase after due diligence;h) the possibility of a price reduction if a relevant risk is identified;i) an obligation to cooperate before public authorities;j) a termination clause if essential omitted information is discovered.

The contractual structure must reflect the real risk of the asset.

A simple contract for a complex asset may generate future litigation.

11. Environmental risk cannot be ignored

Mining and the environment go hand in hand.

An area with a history of mineral exploration may carry environmental liabilities, degraded areas, pits, vegetation suppression, contamination, silting, intervention in Permanent Preservation Areas, irregular road openings, dams, or the need for remediation.

Even if the buyer did not cause the damage, the acquisition of an area with environmental liabilities may generate relevant obligations, restrictions, and costs.

Therefore, due diligence must integrate the real estate, mining, and environmental levels.

It is not enough to ask whether the property is registered.

It is necessary to ask whether the property is usable, licensable, regularizable, and economically secure.

12. Conclusion

Buying land does not automatically mean controlling the subsoil.

In areas with mineral potential, legal analysis must go beyond the registry, possession, and price. It is necessary to verify the situation before the ANM, the existence of third-party mining rights, the compatibility between the intended use and any mining activity, environmental risks, existing contracts, and the economic coherence of the transaction.

The property must be read as a complete structure: surface, subsoil, environment, access, use, restriction, evidence, and responsibility.

When this reading is carried out before the purchase, the transaction is born more secure.

When it is carried out only after the conflict, the buyer may discover that they acquired not only an area, but also a hidden layer of risk.

In transactions involving large areas, mineral potential, or long-term projects, the decisive question is not only:

“Is the registry in order?”

The correct question is:

“Has the entire asset been understood?”
