Southern Copper pays over $1.61B in taxes to Mexico's SAT

Southern Copper Corporation paid more than $1,612 million in taxes to Mexico's tax administration service (SAT) for the fiscal year ended December 31, 2025. The disclosures were submitted in regulatory filings to the US Securities and Exchange Commission (SEC).

Open-pit operations accounted for 96.7% of the Mexican tax payments, driven by the La Caridad and Buenavista complexes operated by subsidiaries Mexicana de Cobre and Operadora de Minas e Instalaciones Mineras. The remaining payments covered underground activities through Industrial Minera México (IMMSA), which operates five underground mines including San Martín and Charcas, alongside an electrolytic zinc refinery in San Luis Potosí.

The payments to Mexico represented 64.9% of the $2,484.6 million total in taxes Southern Copper paid across Mexico, Peru, the United States, Argentina, Chile, and Ecuador. In Peru, the company paid $872.5 million for its Toquepala and Cuajone mining complexes, smelters, refineries, industrial railroad, and port facilities. For small-scale exploration in Ecuador, it paid $2,125 million in taxes.

Southern Copper also reported $130,385.6 million in total royalty payments, with Mexican operations accounting for 11.9% of that total. In addition, the miner allocated $31,691.9 million to social and community responsibility projects, of which Mexico received the largest share at $16,146.7 million.
