Brazil's gold mining industry faces unprecedented regulatory transformation. Growing pressures to formalise production chains and eliminate competitive distortions have created an environment where traditional legal frameworks demonstrate structural inadequacy. The phenomenon of illegal gold mining represents more than an environmental or tax issue – it constitutes a systemic challenge affecting international competitiveness, fiscal collection and Brazil's institutional credibility in the global precious metals market. Understanding the Projeto de Lei do garimpo ilegal de ouro becomes crucial for stakeholders navigating this evolving landscape.
How Does Brazil's New Legislation Aim to Combat Illegal Mining?
Bill 3025/2023, approved by the Chamber of Deputies in April 2026, represents a comprehensive attempt to reformulate control of Brazil's gold chain. The proposal establishes mandatory electronic traceability mechanisms that fundamentally alter regulatory presumptions established decades ago in the national mining sector.
Historical Context of Gold Regulation in Brazil
Brazil's regulatory framework for gold developed gradually since the economic opening of the 1990s, creating a system that prioritised transactional ease over origin control. For decades, the presumption of good faith allowed buyers to accept sellers' declarations about metal origin without independent verification.
This regulatory structure became unsustainable when the Federal Supreme Court, in Direct Action of Unconstitutionality 7,345, determined the elimination of good faith presumption based exclusively on declarations. The decision created a regulatory vacuum that required coordinated legislative response to establish new parameters for control and inspection.
Main Provisions of PL 3025/2023
The project approved by the Chamber establishes four fundamental pillars for gold chain control:
• Mandatory electronic traceability system in all commercial transactions
• Geographical origin documentation with environmental licensing verification
• Compulsory registration of transporters and intermediaries in the supply chain
• Accountability of financial institutions in verifying metal origin
The proposed architecture transfers regulatory competencies from the National Mining Agency (ANM) to the Casa da Moeda, creating a new institutional model for sector supervision. This change represents significant alteration in regulatory governance, concentrating specialised technical functions in an institution traditionally focused on minting and printing activities.

What Economic Impact Does Illegal Mining Have on the Brazilian Market?
Sizing the Irregular Market
Data from Instituto Escolhas reveals substantial transformations in Brazil's illegal gold market between 2022 and 2025. The reduction of approximately 25 tonnes in irregular production during this period represents a decline of R$ 15.3 billion in criminal market movement.
| Indicator | Value | Period |
|---|---|---|
| Reduction in illegal production | 25 tonnes | 2022-2025 |
| Reduced market value | R$ 15.3 billion | 2022-2025 |
| Annual decline rate | Approximately 25% | Estimated base |
This decrease results from coordinated hardening of regulatory, fiscal and judicial measures implemented through cooperation between mining companies, non-governmental organisations, Federal Police, Federal Revenue, Central Bank, Securities Commission and Ministry of Justice.
Macroeconomic Consequences
The illegal gold market creates competitive distortions that harm regular operators through multiple mechanisms. Systematic tax evasion reduces federal and state collection, creating artificial cost advantages for irregular production. Conservative estimates indicate that each tonne of non-taxed gold represents fiscal loss exceeding R$ 600 million in direct and indirect taxes.
Furthermore, unfair competition forces legalised producers to absorb regulatory and environmental costs that illegal competitors avoid. This asymmetry reduces profitability of formal operations and discourages investments in technology and sustainability. The mining permitting basics become increasingly complex for legitimate operators whilst illegal miners circumvent these requirements entirely.
International reputation deterioration affects Brazil's capacity to participate in premium markets requiring origin certification. Due diligence programmes of European and North American refineries increasingly exclude Brazilian gold due to uncertainty about production chains.
Why Does the Mining Industry Criticise the New Proposal?
Organised Productive Sector Positioning
The Brazilian Mining Institute (IBRAM) expresses fundamental concerns about the institutional architecture proposed in the parliamentary substitute. The organisation argues that regulatory competency transfer from ANM to Casa da Moeda compromises technical capacity and operational reach necessary for effective inspection.
Criticisms concentrate on three structural aspects. Institutional capacity deficit: Casa da Moeda lacks regulatory structure and operational capillarity compatible with traceability function complexity. Unlike ANM, which has specific mandate for mineral supervision, Casa da Moeda has expertise in minting and printing, not in commodity regulation.
Private monopoly creation: The project establishes monopolistic structure for traceability through single private company, inhibiting innovation that would result from competition between different technological and operational models.
Taxation without efficacy demonstration: The substitute creates fee for legalised mining companies without presenting impact calculation or benefit demonstration, imposing additional costs on the productive sector without guarantee of effectiveness in combating illegality.
Original Proposal vs. Parliamentary Substitute Comparison
| Aspect | Executive Proposal | Parliamentary Substitute |
|---|---|---|
| Regulatory body | ANM (specialised) | Casa da Moeda (generalist) |
| Traceability structure | Competitive | Monopolistic |
| STF alignment | Direct with ADI 7,345 | Partial |
| Additional taxation | Not specified | Fee on legalised operators |
IBRAM defends that the original executive proposal had merit because it responded directly to the Federal Supreme Court decision, advanced origin control with accountability along the chain and maintained management by the competent regulatory body. They suggest improvements could include clearer rules for mineral sample collection used as reference by Federal Police.
How Does the Proposed Traceability System Work?
Technical Control Mechanisms
The traceability system establishes mandatory electronic documentation accompanying gold from extraction to final commercialisation. Each transaction requires identification of geographical origin with specific extraction coordinates, verification of valid and updated environmental licensing, registration of all intermediaries including transporters and traders, and documentation of purity and quantity with certified laboratory analyses.
The technical architecture requires each property transfer to be registered in a central system, creating unbreakable chain of custody from primary production to final refinement. Unique identification codes link physical and electronic documents, preventing duplication or falsification of records. These systems complement the broader mining claims framework being developed internationally.
Role of Financial Institutions
Banks assume expanded responsibilities in origin verification through multiple mechanisms. Mandatory document verification before processing gold-related financial transactions. Institutions must confirm validity of environmental licences, extraction records and transport documentation before authorising transfers.
Specific prohibitions prevent financial institution owners from acquiring gold directly, eliminating conflicts of interest that historically facilitated money laundering in the sector. Integration with Central Bank systems allows real-time monitoring of suspicious transactions, with automated algorithms identifying patterns incompatible with legitimate operations.
Critical Point: The system's efficacy depends fundamentally on technological infrastructure quality and enforcement capacity of institutions responsible for implementation.
What Are the Implementation Challenges of the New Law?
Operational Capacity of Regulatory Bodies
The transfer of regulatory attributions from ANM to Casa da Moeda raises fundamental questions about institutional adequacy for specialised technical functions. ANM developed specific competencies in geology, mineral engineering and field inspection over decades of operation.
Casa da Moeda, traditionally focused on minting, document printing and digital certification activities, lacks specialised technical structure in geological and mineral analysis, field inspection network with presence in remote mining regions, regulatory expertise in commodity markets and sectoral compliance, and integrated systems with specialised environmental and police bodies.
Informal Sector Resistance
Traditional prospector formalisation represents complex social and economic challenge. Thousands of workers operate in subsistence activities without financial or technical capacity to meet expanded regulatory requirements. Criminal organisation pressure on small producers intensifies when regulatory frameworks become more restrictive, forcing prospectors to choose between activity abandonment or integration with illegal networks offering protection and distribution.
However, these challenges are not unique to Brazil. Similar patterns emerge globally when jurisdictions tighten mining regulations, as evidenced in various mineral exploration insights from international case studies.
Inadequate transition programmes can create social vacuum in regions dependent on artisanal mining, generating unemployment and local economic instability without viable productive alternatives.
What to Expect from Senate Processing?
Current Political Scenario
IBRAM expresses confidence that the Senate will provide opportunities for broad discussion and technical positioning from the mineral sector. This expectation is based on the house's traditional reviewing function, which historically examines Chamber propositions with greater technical detail.
The organisation announces intention to defend revision of critical points and seek restoration of original executive text foundations, specifically those aligned with the Federal Supreme Court decision in ADI 7,345.
Possible Amendments and Modifications
Controversial points identified for revision include institutional competency: restoration of ANM attributions versus maintenance of transfer to Casa da Moeda, traceability structure: elimination of private monopoly in favour of competitive models, additional taxation: revision or elimination of fee on legalised mining companies, and gradual implementation: staggered chronogram for small producer adequacy.
The senatorial process traditionally allows public hearings with technical specialists, sectoral representatives and academics, providing platform for detailed analysis of technical and economic aspects not adequately considered in Chamber processing. Brazil's new legal framework for gold market regulation demonstrates the complexity of these legislative processes.

How Do Other Countries Regulate Gold Mining?
International Benchmarking
Canada operates a decentralised system where federal government establishes minimum standards whilst provinces maintain primary regulatory authority. The Canadian Conflict Minerals Act requires origin certification for exported gold but allows operational flexibility through multiple competing certifying bodies.
Australia implements co-regulation model where industry actively participates in technical standards definition. The Australian Gold Council collaborates with regulatory authorities in developing practice codes that balance regulatory rigour with economic viability.
European Union establishes Conflict Minerals Regulation (EU 2017/821) requiring importer due diligence without creating specific technical barriers for producing countries. Focus concentrates on supply chain traceability instead of direct production regulation.
Learned Lessons and Best Practices
Blockchain technologies demonstrate growing applicability in precious metals traceability. Companies like Tracr (diamonds) and Minespider (diverse metals) have developed platforms allowing independent verification without depending on single intermediaries.
Integration between inspection bodies proves more effective when based on standardised protocols instead of institutional merger. Successful countries maintain institutional specialisations whilst creating technical interfaces for information sharing.
Formalisation programmes demonstrate greater success when including technical assistance for regulatory adequacy, microcredit for certified equipment acquisition, cooperativism for individual compliance cost reduction, and partnerships with buyers guaranteeing certified production distribution.
Specific Brazilian Implementation Challenges
Geographical Complexity
Brazilian territorial vastness creates unique challenges for effective inspection. Regions like Amazon and Pantanal present logistical difficulties that other producing countries don't face, requiring technological solutions adapted for remote monitoring and field verification.
Low population density in mining areas limits face-to-face inspection capacity, making essential the development of automated monitoring systems functioning independently of constant human presence. These challenges occur at a time when gold prices record highs create additional pressure for illegal extraction activities.
Unique Social Aspects
Traditional artisanal mining in Brazil possesses specific sociocultural characteristics significantly different from other producing countries. Riverside and indigenous communities developed extraction techniques over generations, creating economic dependence requiring sensitive approach during regulatory transition.
Organised criminal pressure on prospectors represents more intense phenomenon in Brazil compared to most other producers, requiring coordination between mineral regulation and public security policies.
Future Perspectives for the Brazilian Gold Sector
Possible Post-Approval Scenarios
Optimistic Scenario: Successful implementation results in gradual formalisation of 60-70% of currently irregular production, increasing tax collection and improving international reputation of Brazilian gold. Investments in traceability technology create competitive advantage for certified exports.
Pessimistic Scenario: Inadequate implementation forces illegal production migration to even more remote regions, intensifying environmental impacts and hindering inspection. Excessive regulatory costs reduce legal producer competitiveness, creating perverse incentives for informality.
Intermediate Scenario: Partial implementation achieves mixed results, with significant formalisation in easily accessible regions and illegality persistence in remote areas. System functions adequately for large producers but presents difficulties for small miners.
Strategic Recommendations
For mining companies: Preventive investment in traceability systems before mandatory implementation, strategic partnerships with blockchain and IoT technology suppliers, relationship programmes with prospector communities to facilitate transition, and international certifications anticipated for premium market access.
For policy makers: Gradual institutional strengthening focusing on specialised technical capacity, transition programmes with financial and technical support for small producers, existing system integration instead of parallel architecture creation, and impact monitoring social and economic during implementation.
For civil society: Participation in public hearings during senatorial processing, independent monitoring of implementation through specialised observatories, advocacy for social and environmental safeguard inclusion, and public education about responsible mining importance.
The regulation of Brazilian gold mining through Bill 3025/2023 represents historical milestone that will define sector competitiveness and sustainability for decades. Implementation success will depend fundamentally on capacity to balance regulatory rigour with economic viability, especially for small producers who constitute significant portion of national activity. The ongoing discussions around the Projeto de Lei do garimpo ilegal de ouro reflect broader tensions between environmental protection, economic development and social inclusion.
Furthermore, the timing coincides with a broader historic gold surge in global markets, making effective regulation even more critical. Recent parliamentary approval demonstrates legislative momentum towards comprehensive reform, though implementation challenges remain significant.
