In the dynamism of geological exploration, knowing the exact moment to halt a project or reduce a polygonal area is as vital to the financial health of a mining company as the execution of the drilling itself.
It is a voluntary act through which the holder abdicates their priority right over an area. Whether to concentrate resources on more promising targets or to close projects that did not present economic viability, relinquishment requires technical rigor and attention to the regulatory deadlines of the National Mining Agency (ANM).
Total Relinquishment
It occurs when the miner decides to give up 100% of the area described in the Exploration Permit. This act generates immediate and definitive effects:
- Extinction of the Right: With the filing of the relinquishment, the administrative process is closed and the holder loses any priority over the ground.
- Return to the Union’s Inventory: After ratification and proper publication by the ANM, the area becomes free and may be offered to the market again through an Availability Notice.
Partial Relinquishment
It is the technical choice to cut only the sections of the polygonal area that did not present geological potential, maintaining the priority right over the zones of real interest.
- Target Refinement: Allows the miner to optimize the exploration schedule, focusing investments where the ore was effectively identified.
- Normative Adequacy: This procedure requires the submission of a new descriptive memorial and georeferenced coordinates of the remaining area. It is essential that the new configuration respects the current ANM rules for drawing polygonal areas.
Strategic and Financial Motivators
Why would a miner choose to give up a right? The answer lies in management efficiency:
- TAH Savings: The main financial motivation is to stop the incidence of the Annual Fee per Hectare (TAH). To be exempted from payment for the subsequent period, the relinquishment must be filed mandatorily before the fee’s due date.
- Investment Focus: Reduces direct operational costs with the maintenance of field teams, property security, and fees in areas with no prospect of utilization.
- Risk Mitigation: Prevents the company from maintaining heavy assets on the balance sheet that can generate sanctions for non-compliance with the exploration plan in proven sterile areas.
Remember: Relinquishment does not erase the past. The holder remains legally responsible for any environmental liabilities generated during the work carried out before the withdrawal.
