Mexican Police Raid Hidden Crypto Mining Operation in Puebla

TLDR

• Mexican authorities raided a hidden crypto mining site in Puebla, seizing 300 GPUs and other equipment.
• Investigators are probing whether the mining operation helped launder cartel proceeds.
• The site is the fourth such crypto farm found in the region since early 2025.
• Officials suspect the operation may have stolen power from a nearby hydroelectric dam.
• Past reports show mining has been used before to turn illicit funds into “clean” crypto.

Mexican authorities raided a hidden crypto mining operation hidden in the mountains of Puebla. The raid took place in the town of Tlaola, according to Reuters.

Federal prosecutors, the Mexican navy, and state security officers all took part in the operation. They seized around 300 graphics cards used for mining crypto.

Officials also found a transformer, about 80 medium-voltage terminals, and eight satellite internet antennas at the site.

The equipment was hidden in a remote community, far from major cities. Investigators say the setup required real technical skill and money to build.

Investigators Examine Cartel Ties

Authorities are looking into whether the crypto mined at the site was used to hide profits from illegal activity.

Security analyst David Saucedo told Reuters that cartels appear to be using more advanced methods to hide money.

Mexico’s federal attorney’s office declined to comment on the case because the investigation is still open.

This is not the first mining site found in the area. Three similar operations were discovered nearby last year.

Local officials are now working with neighboring states to search for more hidden mining farms.

How Mining Can Hide Illicit Money

Crypto mining has been tied to money laundering before. The Block reported in 2019 that criminals sometimes buy mining equipment with illegal funds.

This lets them create new coins that appear clean because they were mined directly, not received from another wallet.

A 2023 Chainalysis study found some mining pools also received deposits linked to ransomware and scams.

Chainalysis said mining gives criminals a way to get money with a fully clean, on-chain history.

It is not yet clear how the Puebla operation used its funds. Investigators still need to confirm if power was stolen and if money was laundered.

U.S. officials have also cracked down on cartel-linked crypto transfers. In May, the Treasury Department sanctioned a network accused of moving drug proceeds from the U.S. into crypto for the Sinaloa Cartel.

Chainalysis reported that flagged illicit crypto addresses received at least $154 billion in 2025. The firm said sanctioned entities drove most of that increase.

Despite that total, illicit activity still made up less than 1% of all crypto transaction volume tracked by Chainalysis last year.
