The TMVB mining region has seen a noteworthy amount of silver produced throughout its long history. Two world class deposits that have contributed the most to the silver output of this mineral region in Central Mexico are the low-sulphidation epithermal deposits of Pachuca and El Oro-Tlalpujahua, with 1,400 M Oz Ag and 100 M Oz Ag respectively.
To date, the TMVB has published silver resources contained exclusively in low, intermediate, and high-sulphidation epithermal deposits for over 563 M Oz Ag. The most relevant mineralization style is that of low-sulphidation epithermal affinity, containing over 411 M Oz Ag in eleven mines and projects.
Over 60% of the total silver resources are contained in three deposits: Almaden´s Ixtaca deposit in Puebla State, with published all-inclusive resources for over 134 M Oz of Ag at a grade of 31 g/t Ag, Agnico Eagle´s El Rayo deposit in Jalisco State, with 113 M Oz Ag at a grade of 69.8 g/t Ag, and Angangueo Mine of Grupo Mexico with 109.5 M Oz Ag at a grade of 262 g/t Ag.
These deposits are followed by Monte El Favor deposit in Jalisco State with almost 84 M Oz Ag at a grade of 224 g/t Ag.
Ten additional deposits with less than 60 M Oz Ag occur in the TMVB and plenty of silver exploration plays are widespread in this mining region of Mexico.
The table below shows tonnages, grades, as well as silver resources (all inclusive) for each of these deposits.
