TL;DR
- Mexican authorities seized 1,032 pieces of cryptomining equipment from a suspected illegal operation in Tlaola, Puebla.
- Investigators suspect electricity theft at the crypto mine in Puebla, while its operators and financiers remain unidentified.
- Authorities are searching for similar sites, and no connection between the operation and a specific cartel has been publicly established.
Mexican authorities have widened their search for illegal cryptocurrency mining sites after a raid near a hydroelectric system in Puebla grew from an initial seizure of roughly 300 machines to more than 1,000. The investigation centers on suspected electricity theft. The identity of the operation’s financiers remains unconfirmed.
A second search doubles the seized equipment
Federal and state authorities first entered a remote building in Tlaola, a municipality in Puebla’s Sierra Norte mountain region, on September 3. They disclosed the initial findings on September 6: about 300 graphics processing units, 80 medium-voltage terminals, one transformer and eight satellite antennas.
A second search of the same property on September 11 raised the total to 1,032 pieces of cryptomining equipment, according to the Mexican Navy. Officials described the update as a fuller inventory of the same site, not the discovery of a separate facility. No arrests followed either search.
The facility’s size and location have prompted scrutiny of possible organized-crime involvement. Investigators have not publicly identified its operators or established a connection to a specific cartel.
Power theft, not mining, is the alleged crime
Cryptocurrency mining is not prohibited in Mexico, but that’s also not what authorities are investigating. The alleged illegal conduct concerns the source of the electricity and the connection used to power the machines.
The site stood close to infrastructure linked to the Nuevo Necaxa hydroelectric system. Authorities are probing whether its operators drew electricity illegally from federal power infrastructure.
Mining equipment performs repeated calculations to create or validate units of a cryptocurrency. The process can consume large amounts of electricity, especially when hundreds of machines operate continuously and require cooling. Power is one of a mining operation’s largest expenses. Operators who avoid paying for it remove a major cost while shifting the financial burden and infrastructure risk elsewhere.
Authorities have not disclosed which cryptocurrency the machines were mining. Calling the facility a Bitcoin mine would go beyond the confirmed evidence; the equipment recovered so far consists of GPUs, hardware suited to coins other than Bitcoin.
Noise and electricity demand exposed the site
The Puebla crypto mine sat in a sparsely populated mountain area, but its power consumption and mechanical noise made it difficult to conceal. Two residents told Reuters they could hear the equipment from about one kilometer away. The building stood roughly twice that distance from the nearest village.
Francisco Sánchez González, Puebla’s public security chief, said mining facilities seek remote locations because they consume substantial electricity and produce considerable noise. Electricity consumption and noise led authorities to the property, which state police had already been monitoring for its proximity to the Nuevo Necaxa dam.
Cartel involvement remains unconfirmed
Officials suspect the facility’s technical scale points to organized financing. Investigators have filed no charges, and no wallet addresses have surfaced publicly connecting the site to any proceeds. Who purchased the equipment remains unknown. So does what the machines were mining and where the proceeds went.

Authorities are searching for similar operations
The discovery in Tlaola was not the first in the region. Authorities dismantled three other suspected illegal mining operations in Puebla and neighboring Tlaxcala in 2025, according to El País.
Officials are extending their inquiries to surrounding municipalities and coordinating with nearby states. The mine in Puebla shows how illicit crypto operations can create consequences outside cryptocurrency markets: stolen public electricity and industrial-scale infrastructure disrupting the communities nearby.
How many more sites the joint search turns up, and whether any match Tlaola’s scale, is the question authorities have yet to answer.
