Forget crystal meth. The pseudo-religious Knights Templar drug cartel in western Mexico has diversified to the point that drug trafficking doesn't even rank among its top sources of income.

The cartel counts illegal mining, logging and extortion as its biggest moneymakers, said Alfredo Castillo, the Mexican government's special envoy sent to restore the rule of law in Michoacan, the state controlled by the Knights Templar for the last several years.

Iron ore is their principal source of income, Castillo said. They're charging $15 per metric ton for the process, from extraction to transport, processing, storage, permits and finally export. The ore itself doesn't go for that price; the cartel skims $15 for every ton arriving in port.

While it's long been known that Mexican cartels engage in other types of criminal activity, including trafficking of people and pirated goods, this is the government's first official acknowledgment that a major organized crime group has moved beyond drugs. The Knights Templar and its predecessor, La Familia, started out as major producers and transporters of methamphetamine.

The implications are that organized crime in general in Mexico stands to diversify and become even more entrenched.

It's a criminal organization like the Mafia, said Antonio Mazzitelli, the Mexico and Central America representative to the UN Office on Drugs and Crime. La Familia, the Knights Templar and, in part, the new, smaller cartels that have developed, like the New Generation Jalisco, are copying this new typology.

Mexican authorities count at least 12 major cartels, but also talk of an untold number of smaller splinter groups.

The Zetas cartel, with its strongholds along the US-Mexico border, was among the first to change the business model from merely production and transport of drugs to migrant smuggling and controlling territory through terror. Though drugs still top their list, the Zetas likely make as much from kidnapping and extortion, said Samuel Logan, director of Southern Pulse security consulting firm.

"I've never looked at them as drug-trafficking organizations," Logan said of Mexico's cartels. "They're multinational corporations that will react to market pressures and do what they have to do to stay in business."

The Knights Templar took the model to another level, exploiting the main industries of the territory they control.

Alonso Ancira, president of the National Chamber of Iron and Steel, recently told local journalists that he estimated drug cartels earned $1 billion in profits from selling iron ore in 2013. It was unclear if Ancira was referring only to the illegal mining done by the Knights Templar, and he didn't respond to an interview request from The Associated Press.

As for extortion, Castillo said, information from victims led government experts to estimate that the cartel earned $800,000 to $1.4 million a week just from that crime.

Then-president Felipe Calderon warned against such a stranglehold when he first sent troops to Michoacan in late 2006 to fight La Familia, the predecessor of the Knights Templar. He said the cartel was trying to infiltrate all levels of society.
