Critical Minerals in Brazil | What Foreign Investors Need to Know

What Is Changing in Brazil Regarding Critical Minerals?

Brazil has established a new legal framework for critical and strategic minerals. Law No. 15,506/2026 created the National Policy for Critical and Strategic Minerals (PNMCE) and the National Council for the Industrialization of Critical and Strategic Minerals (CIMCE), with a strong focus on domestic processing, transformation, technological development and value creation.

For foreign investors, however, understanding the new law is only the beginning. The more practical question is whether Brazilian mineral assets are legally secure, properly documented and sufficiently structured to receive investment.

The new LEGAL FRAMEWORK

Law No. 15,506/2026 establishes a national policy designed not only to encourage mineral exploration and production, but also to strengthen processing, transformation, technological development and domestic value chains involving critical and strategic minerals.

The framework also creates mechanisms for project qualification, financing and incentives, making the legal and regulatory condition of individual mineral assets increasingly relevant to investors.

The STRATEGIC CONTEXT OF CRITICAL MINERALS

Critical minerals have become strategic inputs for energy, advanced technology, industrial production and other sectors exposed to supply-chain and geopolitical risks.

Brazil's new policy reflects this international context while seeking greater domestic value creation. The relevant question is therefore no longer simply which critical minerals Brazil possesses, but which Brazilian assets are prepared to participate in the emerging value chains.

The CURRENT LEGAL AND REGULATORY FRAMEWORK

The legislative uncertainty has now been replaced by a formal legal framework. Law No. 15,506/2026 was published on September 16, 2026, and Decree No. 13,118/2026 established the regulatory structure of the CIMCE.

Some practical mechanisms will still depend on further regulation, but investors must now assess the law as part of the existing Brazilian regulatory environment.

Why Does This Matter to Foreign Investors?

Critical Minerals as Strategic Assets

The new framework treats critical and strategic minerals as more than ordinary commodities. It seeks to strengthen Brazil’s mineral value chains while creating conditions for investment, technological development and domestic value creation.

For investors, however, strategic relevance does not automatically make a particular asset investable. The distinction between mineral potential and investment readiness becomes essential.

Growing Competition for Brazilian Mineral Projects

Brazil is increasingly relevant to international efforts to diversify critical-mineral supply chains. At the same time, the new policy encourages projects that contribute to processing, transformation and domestic industrial development.

This may make the quality of individual projects increasingly important. International capital is not simply looking for minerals in the ground; it is also looking for projects capable of advancing through the regulatory and investment process.

Potential Impacts on Foreign Investment

The new framework may affect both projects and transactions. Certain changes in corporate control, significant foreign participation or influence, international agreements and transactions involving relevant mining rights are subject to CIMCE involvement under the new framework.

For foreign investors, this makes the legal structure of both the asset and the proposed transaction an increasingly important part of investment analysis.

The Brazilian Critical Minerals Market May Become More Selective

Two projects involving the same critical mineral may have very different levels of regulatory maturity, documentation, legal security and development readiness.

Not Every Mineral Asset Is Equally Investment-Ready

As the new policy introduces project qualification and support mechanisms, the ability to distinguish between mineral potential and an organized, investment-ready asset becomes increasingly important.

Geological Potential vs. Investment Readiness

Geological potential is fundamental, but it is only one component of the investment equation. A mineral asset also needs a coherent rights structure, reliable documentation, regulatory compliance and a credible path toward development.

For foreign investors, the relevant question is therefore not only “What is in the ground?”, but also “How prepared is the asset to receive capital?”

Why Legal and Regulatory Risks Can Affect Asset Attractiveness

Problems involving mining rights, administrative proceedings, regulatory obligations, documentation or corporate ownership can increase uncertainty, delay development or require additional capital and time.

The issue is not whether an asset has risks. Sophisticated investments routinely involve risks. The relevant question is whether those risks are identified, understood and capable of being addressed.

What Should Investors Verify Before Entering a Brazilian Mineral Asset?

Mining Rights and ANM Records

Investors should verify the status and history of the relevant mining rights, including ANM records, administrative acts, deadlines, obligations and events that may affect the maintenance or development of the right.

The objective is not merely to confirm that an ANM process exists, but to determine whether it provides a sufficiently reliable legal foundation for the proposed investment.

Regulatory and Documentary Compliance

The review should identify regulatory obligations, documentary inconsistencies, pending requirements and other issues that may affect the development or qualification of the project.

The new framework also establishes a traceability system for critical and strategic mineral supply chains, reinforcing the importance of reliable information concerning origin and regulatory, fiscal and socio-environmental compliance.

Legal, Corporate and Project Risks

Investors should also examine ownership structures, corporate control, contractual arrangements and potential disputes. Under the new framework, certain corporate and transactional events involving critical and strategic mineral assets may require CIMCE review or approval.

The relevant question is therefore not simply “Does this project involve a critical mineral?”, but “What exactly am I investing in, what risks accompany it, and what needs to be addressed before the transaction?”.

Mineral Due Diligence and Mineral Asset Structuring

Due Diligence as a Diagnostic Stage

Mineral Due Diligence (DDM) provides a structured assessment of the legal, regulatory and documentary condition of a mineral asset before capital is committed.

Its purpose is to reduce uncertainty, identify material risks and establish a reliable basis for investment, negotiation or further development.

Identifying and Addressing Legal Risks

Identifying a legal risk is only the first step. The investor also needs to understand its significance, potential consequences and whether it can be corrected, mitigated or incorporated into the transaction structure.

A risk is not necessarily a reason to abandon an asset; an unidentified or poorly understood risk is a different problem.

The findings of DDM can provide the foundation for Mineral Asset Structuring (EAM): addressing weaknesses, organizing the asset and preparing it for investment, negotiation or development.

In simple terms: DDM diagnoses the asset; EAM prepares it for the next stage.

The Time to Assess Critical Mineral Assets Is Now

What Investors Should Consider

Brazil’s new critical-minerals framework creates a more defined policy environment, but it does not eliminate the need for asset-level analysis.

Foreign investors should assess at least four dimensions: mining rights, regulatory and documentary compliance, corporate and transaction structures, and overall investment readiness.

The opportunity is not simply to acquire exposure to a critical mineral. It is to identify Brazilian mineral assets with the potential to become investment-ready and understand what is required to get them there.

From Opportunity to Investment Readiness

For investors evaluating Brazilian critical-mineral opportunities, Mineral Due Diligence can be the first step toward understanding an asset’s legal condition, while Mineral Asset Structuring can help prepare it for investment, negotiation or development.
