On May 19, 2025, through Ministerial Agreement No. MEM-MEM-2025-0012-AM, the Minister of the Ministry of Energy and Mines (“MEM”) issued the Guidelines for the Loading, Packaging, Transportation, and Unloading of Copper Mineral Concentrate from Medium-Scale and Large-Scale Mining Operations (hereinafter, the “Guidelines”).
The purpose of the Guidelines is to ensure comprehensive safety, environmental protection, and traceability in the handling of copper mineral concentrate, from mine to the final destination. Compliance is mandatory for all holders of mining rights under the medium- and large-scale mining regimes. The Guidelines apply to all stages of the process, including the loading of concentrate at mining facilities, packaging, transportation by any authorized means (road, rail, among others), and unloading at ports or final destination facilities.
One key provision of the Guidelines is the mandatory use of hermetically sealed containers that meet structural safety and tamper-proof sealing standards. These containers must be dry, clean, and properly certified to prevent any type of leakage. The Guidelines also explicitly prohibit intermediate transfers of concentrate at ports, except in exceptional cases for official sampling by competent authorities.
Cargo generators—that is, mining titleholders responsible for transporting the concentrate—must submit a technical transportation and unloading plan, which will be reviewed and approved by the Competent Administrative Unit of the MEM. Additionally, they are required to implement a real-time monitoring system to ensure visibility, traceability, and transparency of concentrate transportation, and to provide regulatory authorities with access to this information.
The MEM will oversee compliance with these regulations through its Zonal Coordinations, while the Mining Regulation and Control Agency will be responsible for conducting regular technical inspections, issuing compliance reports, and imposing sanctions in the event of non-compliance.
Cargo generators are also required to develop and implement an annual training plan on the technical and environmental handling of the concentrate, which must be submitted to the relevant authority by January 31 of each year.
The Guidelines also establish a sanctioning framework for non-compliance. Sanctions may include monetary penalties or the immediate suspension of operations in cases posing serious risks to health, the environment, or infrastructure. In all cases, sanctioning procedures must observe due process, and the guarantees established in the Constitution and applicable laws.
Furthermore, mining titleholders who are in the production phase and are transporting concentrate as of the publication date of the Guidelines will have a maximum period of 12 months to transition to hermetically sealed transportation systems.
