The Trans-Mexican Volcanic Belt (TMVB) is an active magmatic arc related to subduction of the Rivera and Cocos plates beneath the southern edge of the North America Plate. The TMVB products cover older features of the cordillera over a broad region in central Mexico.
TMVB resources as a function of ore deposit styles include fifteen mining properties with published resources to date of which eleven are low-sulphidation epithermal ore deposits, three deposits are of intermediate-sulphidation epithermal affinity, and just one is a high-sulphidation epithermal deposit.
Other TMVB ore deposit styles with past production but as yet undetermined resources include, volcanogenic massive sulphide (VMS) deposits such as Cuale and Autlan in Jalisco, and Aire Libre in Puebla; porphyry copper deposits such as El Cobre in Veracruz, Agua Blanca and La Sorpresa in Jalisco, and Tiamaro in Michoacan; and skarn deposits such as Las Minas-Tatatila in Veracruz, and Tlamanca and La Preciosa in Puebla.
