This site was fundamental for the productive continuity of this region; the rich veins found in this mine not only placed the district as the second national silver producer during the second half of the 19th century,  but they provided as well the necessary economic resources to continue using steam power and, by the beginning of the 20th century, to introduce electric power.

However, as time passed, mining production decreased and this mine was gradually abandoned. This place is located at the south area of Pachuca, close to the road to Real del Monte and it can only be observed from the exterior.

This is the most emblematic mine of Pachuca during the last 150 years for several reasons: its important production, it was a drainage center, and after the second decade of the 20th century, this mine was the main centralization place for mineral extracted in the different mines of Pachuca, Real del Monte, El Chico and El Cerezo.

This mine is located at San Juan Pachuca district, at the north area of the capital; this district has a lookout point and from this place the mine, Loreto processing plant and a great extension of the city can be observed.

This mine is located at the old Pachuca - Real del Monte beltway, and it can only be observed from the exterior.
