Mexico arrests cartel members linked to murders of 10 workers from Canadian mining company
Mexican authorities announced on Sunday the arrest of five men connected to the kidnapping and murder of 10 workers employed by Vancouver-based mining company Vizsla Silver in the violence-plagued state of Sinaloa.
The workers, all Mexican nationals, were abducted at gunpoint on January 23 from a silver mining project in Concordia, a municipality approximately 50 kilometers southeast of Mazatlán. The area, originally founded in 1565 as a center for precious metals extraction, has a long mining heritage. The victims included two engineers and one geologist among the 10 men taken.
Their bodies were subsequently discovered in clandestine graves. Jaime Castañeda identified his brother, José Manuel Castañeda Hernández, 43, a husband and father of two, through photographs shown by local officials in Mazatlán.
In truth, this has been very painful to be here, in a place where we don't want to be. It's so hard to see how they suffer. There's no justice with what's happening.
Mexico's defense ministry stated that the suspects belonged to a faction of the Sinaloa cartel. One suspect was identified as Jesus Abraham, known by the alias Taliban. The arrests follow a previous June detention of another suspect, Gabriel N., alias Gabito, described as a hitman for the same faction.
Cartel infighting drives mistaken identity killings
According to government officials, the workers were mistakenly identified as members of a rival cartel faction. The confusion stems from violent internal warfare that has torn apart the Sinaloa cartel since September 2024, following the July 2024 kidnapping and handover of Ismael "El Mayo" Zambada to U.S. authorities by a rival faction. The resulting conflict between the Chapitos faction, controlled by the sons of imprisoned druglord Joaquin "El Chapo" Guzman, and the Mayiza faction loyal to Zambada has resulted in more than 2,400 killings and over 2,900 disappearances across Sinaloa state as of early 2026.
El Chapo is currently serving a life sentence in a Supermax prison in Florence, Colorado. His former cartel partner, Zambada, received the same sentence in a U.S. court in July, seven years after El Chapo's conviction.
The Sinaloa cartel was designated as a Foreign Terrorist Organization by the United States on February 20, 2025, under Executive Order 14157.
Mining sector increasingly targeted by organized crime
Vizsla President and CEO Michael Konnert expressed devastation following the discovery of the bodies.
We are devastated by this outcome and the tragic loss of life. Our deepest condolences are with our colleagues' families, friends and co-workers, and the entire community of Concordia.
The company's Panuco project operates in the Panuco-Copala mining district in Concordia municipality, employing approximately 95 people. Mexico produces roughly one-quarter of the world's silver output, making the mining sector economically significant but vulnerable to criminal exploitation.
Mining operations have increasingly become targets for organized crime in Mexico. Since former President Felipe Calderón launched a military campaign against cartels in 2006, criminal groups have diversified into extortion and illegal mining operations, particularly targeting sectors like agriculture, livestock, and mining that operate in rural areas with limited institutional oversight. Reports indicate that mining companies in Mexico face systematic extortion, with some operations allegedly paying protection fees equivalent to 3 percent of revenue to maintain operations.
Abductions by armed groups are common throughout Mexico, where more than 120,000 people have disappeared since the 1950s, many abducted and killed by drug trafficking organizations. However, targeting international companies remains relatively rare, making this incident particularly significant for foreign investment in the country's mining sector.
