Historia de la minería: Louis Laurent Simonin: La vida subterránea

Today we're going to analyze one of the most important books in mining history: Louis Simonin's *Mines and Miners*, published in 1867 and 1869. Louis Simonin was born in 1830 in Marseille, France. He studied at the Saint-Étienne School of Mines, where he earned a degree in mining engineering and geology in 1852. He was a widely recognized professional and developed various projects in France and Italy. In 1859, the French government commissioned him to travel to Cuba, the United States, Central America, Panama, California, and Mexico to study the gold mines in those territories. During this trip, he visited, among others, the Coulterville and Maxwell Creek mines, and later those of Peña Blanca, Big Oak Flat, and Marble Spring, before heading to Northern California. That same year, he received an invitation to take a position at the University of Chile. In January 1860, he became a professor at the National Institute. However, in April of that same year, he resigned, as his professional expectations had not been met. In 1867, he was appointed head of a French commission tasked with conducting preliminary studies and designing the route of the Pacific Railroad. During this expedition, he traveled to what was then known as the Far West. His travels were not solely scientific and related to mining. He also conducted anthropological research on Indigenous peoples, including the Sioux. In this way, Simonin actively participated in the process of industrial expansion westward in the United States. That same year, the first edition of his most important work, *Underground Life: Mines and Miners*, was published. In 1869, the English translation was published under the title *Underground Life; or, Mines and Miners*. On June 15, 1886, Louis Laurent Simonin died in Paris at the age of 55, leaving an important legacy in mining engineering, geology, and scientific outreach. A very important book, covering all aspects of mining, including a history of mining, metallurgy, and mineralogy, as well as methods, techniques, and equipment. The numerous illustrations are of extraordinary quality. The book is divided into three parts: coal mining, metal mining, and gemstone mining. Simonin mentions the Atacama mining district, especially the silver mines such as Tres Puntas and Chañarcillo. On page 332, a section on the mines and deposits of Atacama begins, starting with a geological-metallogenic map of Atacama by David Forbes. It's worth noting that the original version of the book here uses a map by Claudio Gay and Ignacio Domeyko. Interestingly, Simonin names many districts, not just the main ones. He classifies the veins as: gold, silver, copper, and nickel/cobalt. A little later, on page 373, Simonin provides a more detailed description of Chañarcillo.
