What separates a real deal from a promise

Before initiating any advanced negotiation, the buyer must confirm a defined set of parameters regarding the mineral asset: the chain of title registered with the ANM, the permit's status in the regulatory timeline, the technical classification of the resource or reserve, the corporate structure holding the title, and the mechanism for executing the transaction. Each item has direct implications for title risks, registration obligations, and payment conditions. Sequential verification reduces the probability of contingencies that could render the closing unfeasible. The due diligence process, when structured according to the provided checklist, enables decision-making based on documentary and regulatory evidence.

Chain of title#

The chain of title records the succession of acts linking the exploration right to the holder, from the initial concession or authorization to any subsequent assignments and registrations. In the Mining Geographic Information System (SIGMINE), maintained by the ANM, each process has a registration number that consolidates transactions recorded at the notary and subsequent alterations. Consulting the registry of processes allows for the identification of gaps, nullities, or pending issues that compromise the validity of the chain.

Verification includes comparing the surface and subsurface registries, ensuring that the titleholder also possesses the necessary surface rights for supporting works. Discrepancies between these registries may generate regularization demands prior to transfer. SIGMINE provides the history of registrations, allowing the tracking of the date of each assignment and its compliance with the legislation.

The validity of an assignment depends on its registration with the ANM, pursuant to Art. 55, § 1 of Decree-Law 227/1967. Without this registration, the transfer produces no effect before the federal administration, rendering the chain incomplete and subject to contestation in any judicial or administrative dispute.

Title status#

The ANM's “regulatory timeline” defines stages that the title must fulfill from concession to effective exploration, including environmental licenses, deadlines for implementation, and renewal periods. Each phase has specific deadlines that, if not observed, may result in the automatic loss of the exploration right. The status of the title can be consulted in SIGMINE, which contains the start dates of the count, grace periods, and any suspensions.

It is necessary to confirm whether the title is in the “environmental license under analysis,” “operating license,” or “issuance of exploitation plan” phase. The transition between phases requires additional documentation that may be demanded by the buyer as a condition precedent. The absence of an operating license, for example, prevents production and can affect the asset's economic valuation.

Verification also covers the existence of conditional obligations, such as the requirement to initiate infrastructure works within a defined period. Failure to comply with these conditions may result in the expiration of the title, as provided for in the Mining Code. Thus, the current status of the title determines the need for corrective actions before signing a contract.

Technical basis#

The classification of resources and reserves follows the Brazilian System for Mineral Resources and Reserves (SBRRM, ANM Resolution 94/2022), aligned with CRIRSCO: resource (inferred, indicated, or measured) and reserve (probable or proven). The classification must be performed by a qualified professional and registered in the Final Exploration Report (RFP), which indicates the category adopted and the methodology used (geology, modeling, sampling).

The source of technical data must be auditable, allowing for the verification of parameters such as average grade, tonnage, and recovery coefficient. The absence of a technical report signed by a Competent Person compromises the reliability of the estimate and may prevent financing approval. The level of classification directly influences the market value of the asset, as reserves classified as “probable” carry lower revision risk.

It is recommended to validate the report's issue date and the existence of subsequent updates that reflect new drilling or modeling revisions. Significant changes without proper reclassification can lead to discrepancies between commercial information and geological reality.

Structuring#

The corporate structure holding the title is usually organized through holdings that concentrate mining assets in different jurisdictions. The holding registration and the title location may diverge, requiring the analysis of corporate documents, such as articles of association, contract amendments, and commercial registry filings. Identifying the holding's jurisdiction of incorporation allows for the assessment of the applicability of corporate and tax laws relevant to the business.

A hypothetical scenario illustrates the importance of this analysis: an investor acquires a stake in a holding located in another state, but the title remains registered in the name of a different company that was not included in the purchase structure. Without the correct inclusion of this titleholder, the assignment registration with the ANM is ineffective, generating title disputes that can interrupt exploration and lead to significant financial losses.

Verification also includes the existence of liens or guarantees linked to the holding, such as attachments or real guarantees that may limit the availability of the title for transfer. A lack of clarity regarding these charges may require the negotiation of indemnity clauses or the demand for additional guarantees in the purchase and sale agreement.

Transaction mechanism#

The effective transfer of the title occurs through a formal assignment, the validity of which is conditioned upon registration with the ANM, pursuant to Art. 55, § 1 of Decree-Law 227/1967. The purchase and sale agreement usually provides for an escrow, which retains the agreed amount until the registration is proven. The escrow release period is linked to the issuance of the registration certificate, ensuring that the buyer receives the fully registered title before the release of funds.

Market practices, such as those described in the SRS Acquiom study, recommend that the escrow cover both the purchase price and any royalty adjustments or environmental liabilities. The escrow agent, typically a financial institution or specialized company, verifies the registration documentation and, upon confirming compliance, authorizes the transfer of funds to the seller. If registration is not completed within the established timeframe, the contract may provide for the return of funds to the buyer or the application of penalties.

The synchronization between registration and escrow release must be formalized in condition precedent clauses, such that the effectiveness of the transfer depends on the simultaneous completion of both stages. This structure protects both parties against default risks and ensures that the title ownership is effectively consolidated before financial movement.

Verification checklist#

The following list summarizes the critical points that must be confirmed before signing a mineral asset purchase and sale agreement.

1. Consult surface and subsurface registries in SIGMINE.
2. Verify the sequence of registrations in the chain of title, confirming the last recorded assignment.
3. Confirm current title status in the regulatory timeline (environmental license, implementation deadline, conditional obligations).
4. Evaluate the technical exploration report signed by a Competent Person and the resource or reserve classification.
5. Identify the holding company, its jurisdiction of incorporation, and any corporate liens.
6. Review the assignment agreement to ensure a condition precedent clause linked to ANM registration.
7. Define the escrow mechanism, including release timing linked to the registration certificate and coverage of financial adjustments.

Summary#

Compliance with the items described – chain of title, title status, technical basis, corporate structure, and transaction mechanism – constitutes the core of mineral asset due diligence. Each step generates evidence that, when combined, allows the buyer to measure title, regulatory, and operational risks before committing financial resources. The presented checklist organizes this evidence sequentially, ensuring that no essential verification is omitted. By following this procedure, the buyer maintains consistency between legal documentation and the operational reality of the asset, aligning the investment decision with the legal and technical security requirements demanded by the market.
