Mexican authorities have dismantled a suspected clandestine cryptocurrency mining operation. The remote site has been found in the mountainous Tlaola region of Puebla. The authorities have uncovered hundreds of specialized computing units. The authorities are now investigating that the units may be powered using stolen electricity from nearby hydroelectric infrastructure.

Mexico Authorities Seize 300 GPUs From Crypto Mining Site

The operation was conducted by federal prosecutors, the Mexican Navy, and Puebla state police. Authorities discovered approximately 300 graphics processing units (GPUs). Additional equipment found at the site includes 80 medium-voltage terminals, a transformer, and eight satellite antennas. The mining equipment was in operating state when investigators entered the site.

Investigators are now examining whether the facility illegally obtained electricity from infrastructure connected to a hydroelectric system in the Sierra Norte region. Cryptocurrency mining itself is legal in Mexico, so the main probe is the electricity theft. Electricity represents the main operating cost for cryptocurrency mining. If the operators obtained power illegally, they could significantly reduce their expenses.

The Tlaola discovery is reportedly the fourth similar cryptocurrency mining facility found in the region since early 2025. Local residents helped draw attention to the latest site after reporting a loud mechanical noise. Authorities eventually located the facility along a sparsely traveled gravel road in the remote mountainous area. It is not yet clear since when this site was working.

Crypto Mining Raises Cartel Activity Concerns

The investigation has also raised questions about whether organized crime groups could be using cryptocurrency mining. Security analysts have pointed to an increasing use of digital assets by Latin American criminal organizations for transferring money.

Blockchain analytics firm Chainalysis has also reported significant increase in illicit cryptocurrency activity. As per Chainalysis, addresses associated with criminal activity received $154B in cryptocurrencies during 2025.

The case highlights how cryptocurrency mining infrastructure can come under the radar if operations involve suspected power theft or potential links to organized crime.
