Snapshot	Velardeña, better known as Minera Roble, is the second most important mine at the Mexican national level with respect to the extraction of Zinc and is the one with the greatest contribution of this metal for Grupo Peñoles. In 2023, the greatest operating challenge at the Velardeña unit was the drop in zinc, silver, and lead ore grades due to the depletion of the Santa María body. In 2023, Peñoles made investments, allocated to preparation of infrastructure and start-up of diamond-bit drilling stations at the Reina del Cobre project, the preparation of reserves at the Antares bodies (Sur Profundo and Norte Profundo), the development of mining work to generate ore reserves at La Industria, as well as the engineering of a new tailings deposit to guarantee operating continuity.

Deposit type

• Skarn

Summary:

All data has been translated from Spanish with the assistance of AI.

The Velardeña deposit consists of three mineralized bodies known as Antares Norte (northern contact of the Rhyolitic Porphyry), Antares Sur (southern contact of the Rhyolitic Porphyry), and Cuerpo Santa María (partially exploited by IMMSA).

Mineralization: Skarn type with zinc sulfides, and minor amounts of copper, gold, lead, and silver. It is associated with the northern contact of the Rhyolitic Porphyry and the Aplitic Dike that extends from the porphyry.
