Seven municipalities with mining activities will soon receive the approximately US$3.55 M dollars on mining taxes collected by the federal government during 2014 from the State: Lazaro Cardenas, Churumuco, Aquila, La Huacana, Arteaga, Chinicuila and Morelia. The resources are set to be applied mainly on infrastructure projects in the communities.
  • CAMIMEX (Camara Minera de Mexico). Mexico is the world leader in silver production for sixth year in a row, producing 191.5 M Oz of silver, 3.3% more than in 2014. The investment expected in the next few years in new mines and processing capacity expansion amounts to $854 M dollars.
  • Gold production by the main mining companies in Mexico decreased 15% in the first half of 2016. Goldcorp’s Peñasquito in Zacatecas presented a 65% production reduction, mainly due to an expected ore grade decline. Frisco produced 9% less gold, due to recovery issues at its El Coronel mine in Zacatecas.
