It is a baroque-style construction that seeks to pay homage to the discoverers of the Zacatecas mines.

The four sides of the carved quarry display the names and coats of arms of Diego de Ibarra, Juan de Tolosa, Baltasar Treviño de Bañuelos, and Cristóbal de Oñate. At the top, there is a quarry cross on a sphere.
