Embargo and Interdiction: The ANM’s Precautionary Measures in Mining Practice
The role of the National Mining Agency (ANM) as a regulatory body is manifested through various administrative instruments. Among the most impactful are the embargo and interdiction, precautionary measures that result in the paralysis of activities. Although both culminate in the interruption of operations, their natures and scopes of application are distinct. A precise understanding of these differences is decisive for risk management and the maintenance of legal compliance. The objective of this article is, therefore, to delineate the characteristics of each measure, clarifying the scenarios that lead to their application and the consequences for the tenement holder.
Fundamental Differences: Interdiction vs. Embargo
To facilitate understanding, the main distinctions between the two measures can be viewed in the following table:
| Criterion | Interdiction | Embargo |
| Primary Trigger | Grave and imminent risk to life, health, or property. | Non-compliance with legal, technical, or operational obligations. |
| Focus of the Measure | Protection and safety. | Compliance and legality of the work or activity. |
| Basis | Evidence of immediate danger requiring a halt to prevent harm. | Execution of an activity in disagreement with authorizations or licenses. |
| Practical Example | Paralysis of a mining operation due to geotechnical slope instability. | Interruption of a civil work within the mining complex executed without permission. |
Consequences and Developments
The imposition of either of these measures entails direct implications for the enterprise, which must be handled with utmost diligence:
- Lifting of the Measure: Both the embargo and the interdiction are lifted only after the tenement holder proves to the ANM the complete remediation of all irregularities specified in the notice of violation.
- Financial Penalties: Failure to comply with the stop-work order, whether from an embargo or interdiction, subjects the violator to a daily fine, increasing the company’s liabilities.
- Risk of Forfeiture: Recurrence, the accumulation of penalties, and the refusal to remedy irregularities are factors that can substantiate the initiation of an administrative process for the forfeiture of the tenement.
The Role of Compliance with Requirements
In addition to precautionary measures, it is relevant to mention the notification to comply with requirements (Notice of Requirements). Although not an operational “pause,” its consequence is equally terminative for the process.
- Nature: It is a procedural instrument that establishes a deadline for the applicant to provide data or correct deficiencies in the processing of a case.
- Consequence of Non-Compliance: The tenement holder’s inaction within the legal deadline (e.g., 30 days for applications) results in the denial of the request or the disapproval of technical reports, leading to the loss of priority rights over the area.
Diligent management, therefore, encompasses both on-site operational compliance and strict attention to procedural deadlines and formalities. Ígnea offers specialized technical advisory to ensure legal security in all phases of the mining process.
