Although the TMVB is not the most significant mining region in Mexico, it has produced historically a significant amount of gold from several mineralization styles. The most relevant by size are the low-sulphidation epithermal deposits of Pachuca with 7 M Oz and El Oro-Tlalpujahua with 8 M Oz Au.

Currently, the TMVB has published gold resources contained exclusively in low, intermediate, and high-sulphidation epitermal deposits for over 5.8 M Oz Au. Of these, over 3.8M Oz Au occur in eleven low-sulphidation epithermal deposits, 948K oz Au in three properties of intermediate-sulphidation epithermal affinity, and 994K oz Au in a single high-sulphidation epithermal style.

Over half of the total gold resources are contained in two deposits: Almaden´s Ixtaca deposit in Puebla State, with published all-inclusive resources for almost 2 M Oz of Au at a grade of 0.54 g/t Au, and Caballo Blanco in Veracruz State, recently acquired by Candelaria Mining Corp., from Timmins Gold, with almost 1M Oz Au at a grade of 0.58 g/t Au.

These deposits are followed by Candente´s El Oro and Agnico´s El Barqueño deposits with 762K Oz Au at a grade of 3.44 g/t Au and 610K Oz Au at a grade of 0.96 g/t Au respectively.

Eleven additional deposits with less than 500K Oz Au occur in the TMVB and plenty of gold exploration plays are widespread in this mining region of Mexico.

The table below shows tonnages, grades, as well as gold resources (all inclusive) for each of these Deposits.
