Although the TMVB has not been historically a mineral region with significant copper-lead-zinc ore deposits, it has seen relevant base metal past production, as is the case of Cuale mining district. Just in the period 1980-1990, Fresnillo Company produced from over 18 volcanogenic massive sulphide deposits in this mining district, over 13 M Lb Cu, 57 M lb Pb, and 179 M Lb Zn from 2.47 M tons with grades of 0.23% Cu, 1.03% Pb, and 3.22% Zn (plus Au & Ag credits).

At this time, the TMVB region has two mines with published resources of copper, lead, and zinc: the San Martin Bolaños Mine in Jalisco State owned by First Majestic (now in production), and Angangueo Mine in Michoacan State which is in turn owned by Grupo Mexico, and expected to re-start production soon.

To date, the TMVB has published resources for over 297 M Lb Cu, 350 M Lb Pb, and 835 M Lb Zn, contained exclusively in low-intermediate sulphidation epithermal deposits.

The table below shows tonnages, grades, as well as copper, lead, and zinc resources (all inclusive) for each of these deposits.
