Guarisamey
Guarisamey lies in the deep western valleys of the Sierra Madre Occidental, within a region rich in silver and gold. Its mines drew settlers into a difficult mountain landscape during the eighteenth century. In 1784 José Fernández and Cayetano Flores discovered the Tecolotita mine near the Piaxtla River, renewing the fortunes of Guarisamey. The mining district also drew the investment of Juan José Zambrano, one of the prominent entrepreneurs of late colonial Durango.
