Figure 1. Francisco Daniel Restrepo Escobar, circa 1906. Restrepo began his career at gold and silver mines in the Colombian states of Antioquia and Tolima in the 1870s and 1880s. He is credited with rediscovery of the Chivor emerald mines, an event that evidence also places in the 1880s. The early 1900s found him at gold mines in Ecuador and then leading operations at the Muzo emerald mines. In the 1910s, he returned to Chivor, where he would cooperate with German miner Fritz Klein to find investment funding for the project. Courtesy of Eduardo Restrepo Ortega.
