How a Hidden Crypto Mine in Puebla Was Found—and What Investigators Still Don’t Know

A remote cryptocurrency-mining site in Tlaola, in Puebla’s Sierra Norte, was difficult to spot from a lightly traveled road—but its persistent machinery noise and unusually high electricity use drew attention. Authorities found a substantial operation inside: about 300 graphics processing units (GPUs), 80 medium-voltage electrical terminals and eight satellite antennas. Investigators are examining possible electricity theft and other leads, but the available reporting does not establish who controlled the site or whether it was linked to a cartel. 178

What authorities found

The equipment points to a large-scale mining setup rather than an ordinary computer room. The GPUs were accompanied by electrical infrastructure and satellite antennas at a secluded property in Tlaola. The mine’s remote setting helped keep it out of view, while the sound of its machinery and its power demand—described as far above the needs of nearby small communities—helped investigators locate it. 18

Why electricity became a central lead

Mining equipment needs substantial power to run and cool. Authorities are investigating whether the Puebla site drew electricity without authorization from infrastructure connected to a nearby hydroelectric system. Puebla’s public security authorities identified energy theft as a main line of inquiry and said investigators would look for similar facilities in neighboring municipalities. 17

That allegation matters to the operation’s economics: if a mine used power without paying for it, it could avoid a major operating expense. But the reporting describes a suspected connection, not a confirmed finding that this particular site stole electricity. The case also shows how physical clues—an abnormal power draw and conspicuous machinery noise—can help direct an investigation toward a hidden computing operation. 17

A fourth reported discovery, not proof of a network

Reports describe the Tlaola site as the fourth comparable crypto-mining farm found in the area since early 2025, after three earlier discoveries. That history gives authorities reason to look for more sites, but it does not by itself establish that the farms were connected or shared the same operators. 3

Reporting has also raised questions about possible organized-crime involvement and the use of mining to generate or disguise illicit funds. Those are investigative concerns, not proof that a cartel owned this farm. The sources available here do not identify its operator or trace the coins mined at the site to criminal proceeds. 17

How the case fits into wider crypto-crime figures

The Puebla investigation is local; global estimates should not be mistaken for evidence about this mine. Chainalysis estimated that illicit cryptocurrency addresses received at least $154 billion in 2025, compared with $59 billion in 2024. The estimate covers illicit addresses identified by the firm and describes global flows—not mining revenue, Mexican cartel activity or funds connected to the Tlaola site. 3536

The distinction is important: a mining operation can be investigated for its power supply and possible financial links without those suspicions proving a criminal connection. For now, the clearest findings are the equipment authorities reported seizing and the unusual power use and noise that helped expose the facility; the source of its electricity, its ownership and the destination of any mined assets remain unresolved in the reporting. 17
