Hidden Crypto Mining Farm in Mexico Raises Cartel Funding Concerns

Highlights:

• Mexican authorities are investigating a hidden crypto mining site in Puebla for possible electricity theft.
• Police found 300 GPUs at the remote facility, while possible cartel links remain unconfirmed by authorities.
• Officials are checking nearby regions for similar sites as concerns grow over criminals’ use of crypto.

Mexican authorities are investigating a hidden cryptocurrency mining operation found in the mountains of Puebla state, including whether it used stolen electricity and helped move illicit funds. The discovery has also raised fresh concerns over organized crime groups using crypto mining and digital assets to support financial operations.

Reuters reported the case on September 12 after authorities uncovered the mining site in the Sierra Norte region of Puebla. The facility was operating from a remote building near a hydroelectric system, far from heavily populated areas. Investigators have not publicly identified who controlled the operation.

Authorities Find 300 GPUs at Puebla Crypto Mining Site

Police found 300 graphics processing units, 80 medium-voltage terminals and eight satellite antennas inside the facility. The equipment could be used for cryptocurrency mining, a process in which powerful computers perform calculations to earn digital assets. The Puebla operation was relatively small compared with major commercial crypto mining farms. However, authorities have since discovered four similar sites in the area. Three others were found near the same hydroelectric dam in northern Puebla.

Investigators are now examining whether the latest operation illegally drew electricity from nearby infrastructure. Electricity is one of the largest expenses for crypto miners because running and cooling mining equipment requires large amounts of power. The University of Cambridge’s Bitcoin Electricity Consumption Index estimates that producing one Bitcoin can cost close to $45,000. Bitcoin was trading around $78,000 when Reuters published its report, leaving a potentially large margin if it avoided electricity costs.

Security analyst David Saucedo said the scale and technical setup suggested access to significant resources. “Drug cartels appear to have reached a new level of sophistication,” Saucedo added. However, authorities have not confirmed that a specific cartel owned or operated the Puebla facility.

Crypto Use Grows Alongside Organized Crime Concerns

The case comes as criminal groups increasingly experiment with cryptocurrency transfers and mining alongside more traditional financial methods. Chainalysis data showed that addresses linked to illicit activity received an estimated $154 billion in cryptocurrency during 2025, compared with $59 billion a year earlier. Much of that increase was connected to sanctions-related activity, including transactions involving sanctioned governments.

Caio Motta, Chainalysis’ Latin America specialist, said mining locations can become attractive to criminal groups when cheap power is available, or electricity can be stolen in areas where organized crime has influence. The remote terrain around Sierra Norte may have made the Puebla facility harder to detect. Residents from nearby communities told Reuters they could hear the mining equipment from about one kilometre away, while the site was roughly twice that distance from the nearest village.

Authorities in Puebla are working with neighboring states to determine whether more hidden crypto mining operations are active in the region. At the same time, blockchain tracing tools are giving investigators more ways to follow cryptocurrency transactions linked to organized crime.
