In the Brazilian mining scenario, the time between mineral exploration and the actual granting of the Mining Lease can be a challenge for companies’ cash flow. In this context, the Experimental mining license (GU) arises, a strategic tool that allows the extraction of mineral substances while the Exploration Permit is still valid.
However, to use this mechanism, approval from the National Mining Agency (ANM) is not enough. There is an inseparable link with the competent environmental agency.
In this article, we will detail how the GU works and its mandatory dependency relationship with environmental licensing.
What is the Experimental mining license?
The Experimental mining license is an authorization of an exceptional nature. It allows the holder to begin mineral extraction in the titled area before the definitive issuance of the Mining Lease.
The goal is not to replace the final title, but rather to enable tests and operational costs while the main process is underway.
The Link: GU and Environmental Licensing
For the miner, it is crucial to understand that the ANM’s favorable technical decision regarding the GU has no isolated validity. The effectiveness of this title is strictly conditioned upon environmental regularity.
The relationship is based on two fundamental pillars:
1. Condition of Effectiveness
The GU only has legal validity if accompanied by the pertinent environmental license (usually the Operating License) or equivalent document issued by the competent state or municipal environmental agency. Without environmental endorsement, the mining authorization from the ANM is innocuous.
2. Procedure and Strict Deadlines
The administrative flow requires attention. After the ANM issues the favorable decision for the issuance of the GU, the holder must present the valid environmental license in the process.
Generally, the deadline stipulated for this presentation is 10 days. Failure to meet this requirement may result in the cancellation of the authorization, halting any early extraction operation.
Technical Justifications for Application
Because it is an exceptional mechanism, obtaining the GU requires the miner to prove the need for immediate extraction through a report prepared by a qualified professional. The ANM accepts three main technical justifications:
Assessment of technical-economic viability: Necessary to test the ore’s acceptance in the market and validate its commercial value (national or international).
Analysis and industrial testing: Fundamental for carrying out processing, beneficiation, or industrial application tests on a full scale before the final grant.
Commercialization: Allows continued supply to guarantee market share or, crucially, to fund the Mineral Exploration work itself.
The Experimental mining license is a powerful accelerator for mining projects, allowing revenue generation and technical validation before the final lease phase. However, its application is null without perfect alignment with Environmental Licensing. The synchrony between mining engineering and environmental management is what guarantees the legal security of this operation.
