The distance between compliance and the loss of a tenement is measured by the precision in fulfilling administrative obligations. The mining process is composed of a succession of events, payments, protocols, reports, and updates, which require constant technical oversight.
It is in this scenario that Administrative Expert Reports arise—instruments that determine the compliance of specific stages and ensure that the miner is operating on solid ground.
What is an Administrative Expert Report?
Unlike a portfolio audit, which analyzes the complete history of several mining rights, an Administrative Expert Report is a punctual technical analysis. It focuses on an event or a specific set of events within the process at the National Mining Agency (ANM).
The objective is to issue a specialized opinion on the legality and compliance of an administrative action, serving as an “official photograph” of that moment in the process.
When is it necessary?
There are milestones in the life of a tenement where an administrative expert report is not only useful but indispensable:
- Compliance with Official Requirements: When the ANM issues a complex notification, the administrative expert report validates whether the miner’s response strictly meets the technical and legal requirements.
- Due Diligence and Negotiations: In processes of buying, selling, or transferring mining rights (Assignment of Rights), the administrative expert report focuses on crucial stages (such as the payment of CFEM or the regularity of the RAL) to ensure that the buyer does not inherit hidden liabilities.
- Regularization of Fees and Charges: To validate whether the calculation and payment of fees (such as the TFRM or the Annual Tax per Hectare – TAH) were performed correctly, avoiding fines and interest.
- Documentary Evidence for Legal Defenses: In cases of litigation or forfeiture processes, the administrative expert report serves as technical evidence that the miner fulfilled their obligations within the deadline and in accordance with the law.
To have validity and technical strength, the administrative expert report must include:
- Chronological Analysis: Verification of deadlines and the timeliness of the protocol.
- Regulatory Compliance: Comparison of the action taken with the ANM resolution in force at the time of the event.
- Risk Diagnosis: Identification of possible flaws that could generate future sanctions.
- Conclusive Opinion: Certification that this stage is, or is not, in compliance with the Mining Code.
Often, the miner believes that their process is regular simply because they have an active tenement. However, an administrative failure in an event from two years ago can be a “time bomb”. The administrative expert report allows identifying and resolving these blind spots without the need for a full audit, optimizing time and resources.
