The Spanish discovered silver lodes here in 1531, which started commercial silver mining in the area. Francisco de Hoyos and Juan Juan Jaramillo made the discovery when returning from a military expedition to Guerrero. Using Indian slave labor until the ban from doing so was enforced in 1550, the resultant mines produced 1000 pounds of silver by 1539. Prominent mine owners included Juan de Burgos and Hernan Cortes. Most of the mines were abandoned by 1582 however.Geography
