The Valenciana Mine, known as Mina de La Valenciana in Spanish, is located in Guanajuato, Mexico. Valenciana is about 6 km from the Historic Center, Guanajuato, Guanajuato.[1][2] La Valenciana Mine, Historic Guanajuato City, and surrounding mines are part of a UNESCO World Heritage Site.[3] It began to exploit silver in the 16th century.[4] Its extraction of silver was so abundant that its production was equivalent to two-thirds of the total that was obtained from this metal in all of New Spain.[5] Currently, it belongs to the Santa Fe Cooperative Society of Metallurgical Mines of Guanajuato and continues to be exploited at a depth of 760 meters.
