Mexican authorities have seized a clandestine cryptocurrency mining operation hidden in the mountains of Puebla as investigators examine whether the facility was being used to launder money connected to criminal activity.
The operation was discovered in Tlaola, in the Sierra Norte region of central Mexico, where hundreds of specialized computers had been installed inside a remote property. Reuters reports that the site is suspected of mining cryptocurrency to launder illicit funds.
The investigation is still active, and authorities have not publicly identified a specific cartel as the operator of the facility.
Around 300 Mining Systems Seized
The property was secured during a joint operation involving Mexico's Federal Attorney General's Office, the Mexican Navy, and Puebla state security authorities.
According to the official Puebla government announcement, investigators found approximately:
• 300 specialized GPU computing systems
• 80 medium-voltage electrical terminals
• Eight satellite internet antennas
• A pedestal-mounted electrical transformer
The equipment was actively operating when authorities entered the property.
Authorities said the building and equipment have been placed under official control while investigators determine how the operation was financed and how the cryptocurrency it generated was being used.
Possible Electricity Theft From Hydroelectric Infrastructure
The enormous electricity requirements of the mining operation are also part of the investigation.
Cryptocurrency mining requires large amounts of electricity to operate and cool specialized computing equipment, making power one of the largest expenses associated with running a mining facility.
If operators were stealing electricity, that could dramatically reduce the cost of generating cryptocurrency.
The remote location also helped conceal the operation. Residents in nearby communities told Reuters that the mechanical noise produced by the equipment could be heard from roughly one kilometer away, while the facility itself was located around twice that distance from the nearest village.
Fourth Crypto Farm Found in the Area
The Tlaola facility is reportedly not an isolated discovery.
It is the fourth clandestine cryptocurrency mining operation uncovered in the area since early 2025, according to Reuters' investigation into the growing use of cryptocurrency by Mexican organized crime groups.
Three similar operations were previously discovered near the hydroelectric dam in northern Puebla.
Authorities are now working with neighboring states to determine whether additional mining facilities may be operating elsewhere in the region.
Possible Money Laundering Under Investigation
The Puebla government says investigators are analyzing whether cryptocurrency generated through the seized infrastructure may have been used to make money connected to illegal activities appear legitimate.
The state government's September 6 statement specifically said authorities are investigating whether the virtual assets generated at the property could have been used to give an appearance of legality to resources linked to illicit activity.
That is an important distinction because authorities have not yet publicly concluded that the facility was operated by a cartel or proven that the cryptocurrency generated there was successfully laundered.
Mexico's federal attorney's office declined to provide Reuters with additional information, citing the ongoing investigation.
Cartels Increasingly Turning to Cryptocurrency
Mexican organized crime groups have increasingly incorporated cryptocurrency into their financial operations alongside more traditional money laundering methods.
Caio Motta, a Latin America specialist at blockchain analytics company Chainalysis, told Reuters that criminal groups can use mining operations in areas where electricity is inexpensive or where organized crime has enough influence to steal power.
Security analyst David Saucedo said establishing an operation like the one discovered in Puebla would require both technical expertise and substantial financial backing, suggesting that a well-funded criminal organization could be involved.
However, no specific cartel has been officially named in connection with the seized facility.
Illicit Crypto Transactions Continue to Grow
The discovery comes as cryptocurrency plays an increasingly significant role in global financial crime.
Chainalysis estimates that cryptocurrency addresses linked to illicit activity received approximately $154 billion during 2025, more than double the roughly $59 billion recorded a year earlier. Much of that increase was attributed to sanctions-related activity rather than cartel financing alone. Reuters details the wider increase in illicit cryptocurrency transactions here.
At the same time, blockchain transactions can often be traced, giving investigators another avenue for identifying and disrupting criminal financial networks.
For now, the Tlaola property remains under investigation as Mexican authorities work to determine who financed the mining infrastructure, whether electricity was stolen, and whether the cryptocurrency generated by the operation was ultimately being used to launder criminal proceeds.
