The mines that made Guanajuato rich are inside and just outside the city proper. A number of these mines gave rise to small communities with their own churches; these still exist with other institutions such as museums. The best-known mines gave their names to a number of the city's oldest neighborhoods such as Cata, Rayas y Mellado, La Pastita, San Luisito and Valenciana. Some of these mines are open to the public for tours.<ref name="rincones103">Gonzalez, p. 103</ref> The first significant mine was called San Bernabé, which brought thousands of adventurers to Guanajuato and led to the discovery of other mineral deposits. This mine functioned from the 16th century until 1928. The remains of this mine can still be found in the small village of La Luz just outside the city.<ref name="leyendasgto20"/>

The most important of these mining complexes is [[Valenciana Mine|La Valenciana mine]], on the northern edge of the city. It began operation in 1774. From then until the early 19th century<ref name="stampart43">Guanajuato, p. 43</ref> it was one of the most productive silver mines in the world, accounting for 2/3 of the world's production at its peak.<ref name="mexconnect"/> It produced 80% of all silver mined in the state of Guanajuato and one-sixth of all Mexico.<ref name="rincones104"/> For over 250 years, it produced about 30% of the world's silver. The mine continues operation today. Production is much diminished, but one ton of rock is still extracted every six minutes. The largest shaft descends for 450 meters and about 10,000 miners have worked it over its history.<ref name="descubre"/>

The mine made its owners, the Counts of Valenciana, extremely wealthy and powerful. The first Count of Valenciana, Antonio de Obregón y Alcocer had the [[La Valenciana Church (San Cayetano)|San Cayetano Church]] (also known as La Valenciana Church) built near the entrance of this mine.<ref name="rincones105">Gonzalez, p. 105</ref> Dedicated to [[Saint Cajetan]], it was built between 1765 and 1788. The church has a [[Churrigueresque]] portal, which has been compared to the [[Mexico City Cathedral]] and [[La Santisima Church]], both in Mexico City. The interior conserves a number of gilded altarpieces and a pulpit that is encrusted with ivory and precious hardwoods.<ref name="mexdesgto"/><ref name="rincones105"/> The interior also contains [[agraffito]] work and paintings from the 19th century.<ref name="stampart40">Guanajuato, p. 40</ref>

Near La Valenciana Mine is the Guadalupe Mine, established in the 16th century. This complex was built with extremely large and thick stone walls supported by buttresses, giving it the look of a medieval fortress. The mine is no longer in operation but the complex has been undergoing redevelopment as a resort.<ref name="descubre"/><ref name="stampart44">Guanajuato, p. 44</ref>

La Cata mine is one of the early mines, and a city neighborhood is named after it. The mine is near Don Quijote Plaza. It began operations in 1558 with peak production in the first quarter of the 18th century. It was owned by the Marquis of San Clemente.<ref name="descubre"/> The center of the neighborhood is Señor de Villaseca Church, more commonly called La Cata Church. This church was built in the 17th century in Mexican Baroque or [[Churrigueresque]] style similar to that of La Valenciana Church. The church holds a valued crucifix called the Señor del Villaseca and is registered as a Mexican Federal Historic Monument.<ref name="mexdesgto"/><ref name="rincones105"/>

The Bocamina de San Ramón mine is one of the city's early mines, with the deposit found by some travelers in the early 16th century. In 1548, its mother lode was found. Today, the mine is a tourist attraction in which visitors can descend into the earth through the old shafts. The complex has a patio area, a gallery of minerals and a bar called El Petardo, which once was the gunpowder storage room.<ref name="descubre"/>

The Rayas mine gave rise to one of the city's original neighborhoods, after having been found in 1550 by Juan Rayas.<ref name="stampart43"/> The mine's apogee occurred in the 18th century, giving its owner, José de Sardineta y Legaspi the titles of Viscount of Sardineta and Marquis of Rayas. Today it is found on a section of the Carretera Panorámica (Panoramic Highway) that circles the city.<ref name="descubre"/> The complex walls are tall and are held up by stone buttresses.<ref name="stampart43"/> It has one of the longest mine shafts in the world, which extends into the earth for 425 meters.<ref name="descubre"/><ref name="stampart43"/>

The Castile of Santa Cecilia is a majestic medieval-style construction built on a former 17th century mining hacienda. The current building functions as a hotel.<ref name="stampart45">Guanajuato, p. 45</ref>
