SnapshotFresnillo is one of the world’s oldest continuously operating mines. In operation since 1554.

At the Fresnillo mine, the MD5000 tunnel boring machine resumed operations in the second half of 2024, enabling to continue of developing the main haulage level at the western end of the mine.

In addition, the San Carlos shaft is now operational, reducing haulage distances and cutting costs. The shaft is scheduled to operate for the whole of 2025.

Summary:

The Fresnillo mine ore deposits consist of replacement chimney and manto bodies, disseminated sulfide bodies, and vein deposits hosted mainly in Cretaceous marine sedimentary and volcanic rocks.

The base metal-silver deposits are zoned to the southeast away from a small quartz monzonite stock, with increasing silver content and decreasing base metal values with distance from the stock. Wall rocks adjacent to the stock exhibit silicification and calc-silicate alteration that has been partially replaced by the sulfide minerals. Vein wall rocks exhibit potassic, phyllic, argillic, and propylitic alteration with increasing distance from the veins.Chimney and manto bodies contain pyrite, pyrrhotite, sphalerite, chalcopyrite, galena, tetrahedrite, marcasite, arsenopyrite, and silver minerals. Chimney and manto bodies predate or are contemporaneous with base metal veins containing a similar mineralogy. Younger silver-rich veins consist primarily of pyrargyrite with lesser acanthite, proustite, miargyrite, polybasite, tetrahedrite, galena, sphalerite, and chalcopyrite. Individual veins exhibit increasing silver and decreasing base metal concentrations with increasing elevation.
