How to Request a Geological Reconnaissance Permit at the ANM


Obtaining a Geological Reconnaissance Permit is a technical step that demands documentary precision and systemic agility. Because it involves aerial surveys, the process extends beyond the National Mining Agency (ANM) and involves national security protocols.


1. Fundamental Prerequisite: Ministry of Defense Approval.

Unlike other mining titles, Geological Reconnaissance strictly requires proof of registration with the Armed Forces General Staff (EMFA), under the Ministry of Defense. The requesting company (or its contractor) must hold a valid authorization for aerial surveys (Category A or B registration). Without this document, the permit will not be granted.


2. The Workflow in the Mining Registry System

The process begins in the digital environment:

  • Pre-request: Access the system, select “Geological Reconnaissance Request,” and fill in the required data.
  • Polygonal Area: Define the area of interest using geographic coordinates in the SIRGAS 2000 Datum.
  • Fees: Issue and pay the official fee (GRU) for the “Prior Consent for Geophysical Aerial Survey.”

3. Required Documentation

The Digital Protocol must include:

  • Corporate Credentials: Updated corporate data and legal representation.
  • EMFA Proof: Document of technical capacity and current flight authorization.
  • Flight Plan: Detailing the entire survey area, including flight altitude and line spacing.
  • Technical Memorandum: Description of the geophysical and photogrammetric equipment to be used.
  • Georeferenced Map: Provided at an appropriate scale for the intended area.

4. Deadlines and Temporary Nature

This permit is temporary and revocable (precarious status), with a maximum term of 90 days starting from its publication in the Official Gazette (DOU).

  • No Extensions: The timeframe is fixed for flight execution and data collection.
  • Priority Rights: During these 90 days, the titleholder holds the exclusive right to file an Exploration Permit Request. Failure to do so results in the area being automatically released.

5. Final Obligation: Submission of Results

The process does not end with the survey. Upon concluding the aerial studies, the company is mandatory required to present all data and results to the ANM. Errors in the flight plan or EMFA documentation can jeopardize priority rights over a promising area.

At ÍGNEA, we support companies through every stage, from flight planning to the final ANM protocol, ensuring that technology and mining law work in perfect alignment.
