The mine was rediscovered in 2014 during a routine structural inspection of the hotel foundation.
The tunnels were sealed for centuries and remained largely untouched until their mid-2010s excavation.
Geologists have identified original veins of silver and gold still embedded in the rock walls of the mine.
The site illustrates the shift from indigenous mining techniques to the more aggressive methods introduced by the Spanish.
The Pre-Hispanic Mine of Taxco is an underground excavation site located beneath the Hotel De La Misión, showcasing silver mining techniques used prior to the Spanish Conquest. Discovered by accident during hotel renovations, the site reveals original tunnels and veins of silver ore. Visitors navigate narrow, dimly lit subterranean passages that maintain a consistently cool temperature. The mine features instructional displays explaining the labor practices of indigenous miners during the colonial transition. It remains one of the few accessible examples of pre-colonial extraction methods in the region.

Wear comfortable, non-slip footwear as the ground inside the tunnels can be uneven and slick.
The temperature drops significantly underground, so bring a light jacket even on warm days.
Avoid this tour if you suffer from claustrophobia, as the passages are narrow and ceilings are low.
Do not attempt to enter the tunnels without a certified guide, as the structural integrity varies by section.
Hard hats are provided and must be worn at all times; follow guide instructions regarding touching the rock walls.
