Decree 449/2025: Key Changes to Argentina’s Mining Investment Regime

July 7, Decree 449/2025 was published in the Official Gazette, introducing significant reforms to this law and also to Law No. 24.466. In line with the national government’s objectives of reducing bureaucracy, eliminating overlapping functions, and facilitating private development in strategic sectors such as mining.

Key changes include:

- Immediate Application:
The decree is effective upon publication and also applies to pending procedures, meaning it will have a direct impact on projects currently underway.
These reforms not only modernize the legal framework but also reflect a shift in regulatory approach toward simplification, institutional efficiency, and greater predictability for investors.
