In the great barranca known today as Copper Canyon, the small mining town of Batopilas once experienced a silver bonanza among the largest ever known. American investors, believing that Mexico offered an unexploited cornucopia, began purchasing mines in the Sierra Madre, seeking to expand their hold on natural resources outside U.S. borders. From 1861 until the Revolution of 1910, the men of the Batopilas Mining Company ruled the region using their wealth, armed might, and extensive connections. The technology, industrialism, and politics their interests brought to this remote community tied the Tarahumara, Yaqui, Mayo, and other peoples of the barrancas directly to the economies of the United States and China. Local society was revolutionized, and a dramatic tapestry of human interactions was created. Based on many volumes of mining company records, The Silver of the Sierra Madre exposes the mentality and methods of mine owners John Robinson and Alexander “Boss” Shepherd, vividly detailing their exploitation of the people and the natural resources of Chihuahua. Hart aptly demonstrates the human and financial losses resulting from President Porfirio Díaz’s development programs, which relied on foreign investors, foreign managers, and foreign technology. This unprecedented work also provides a highly interesting ethnographic and social description of one of the least-known areas of Mexico. It is a tale of power and desperation, respect and arrogance, adventure and tragedy, and, ultimately, triumph and survival.
Within the last decade, the high and continuing demand for gold has prompted a global gold rush on a scale never before seen, not even in the heady days of Ballarat, California and the Yukon. Gold is being sought on every continent and, with very few exceptions, in every country around the world. Such interest and fierce competition has demanded considerable innovation and improvement in exploration techniques paralleled by a rapid expansion of the geological database and consequent genetic modelling for the many different types of gold deposits now recognized. This proliferation of data has swamped the literature and left explorationist and academic alike unable to sift more than a small proportion of the accumulating information. This new book represents an attempt to address this major problem by providing succinct syntheses of all major aspects of gold metallogeny and exploration, ranging from the chemical distribution of gold in the Earth's crust, and the hydrothermal chemistry of gold, to Archaean and Phanerozoic lode deposits, epithermal environments, chemical sediments, and placer deposits, and culminates in chapters devoted to geochemical and geophysical exploration, and the economics of gold deposits. Each chapter is written by geoscientists who are acknowledged internationally in their respective fields, thus guaranteeing a broad yet up-to-date coverage. In addition, each chapter is accompanied by reference lists which provide readers with access to the most pertinent and useful publications.

Long before the Spanish colonizers established it in 1598, the “Kingdom of Nuevo México” had existed as an imaginary world—and not the one based on European medieval legend so often said to have driven the Spaniards’ ambitions in the New World. What the conquistadors sought in the 1500s, it seems, was what the native Mesoamerican Indians who took part in north-going conquest expeditions also sought: a return to the Aztecs’ mythic land of origin, Aztlan. Employing long-overlooked historical and anthropological evidence, Danna A. Levin Rojo reveals how ideas these natives held about their own past helped determine where Spanish explorers would go and what they would conquer in the northwest frontier of New Spain—present-day New Mexico and Arizona. Return to Aztlan thus remaps an extraordinary century during which, for the first time, Western minds were seduced by Native American historical memories. Levin Rojo recounts a transformation—of an abstract geographic space, the imaginary world of Aztlan, into a concrete sociopolitical place. Drawing on a wide variety of early maps, colonial chronicles, soldier reports, letters, and native codices, she charts the gradual redefinition of native and Spanish cultural identity—and shows that the Spanish saw in Nahua, or Aztec, civilization an equivalence to their own. A deviation in European colonial naming practices provides the first clue that a transformation of Aztlan from imaginary to concrete world was taking place: Nuevo México is the only place-name from the early colonial period in which Europeans combined the adjective “new” with an American Indian name. With this toponym, Spaniards referenced both Mexico-Tenochtitlan, the indigenous metropolis whose destruction made possible the birth of New Spain itself, and Aztlan, the ancient Mexicans’ place of origin. Levin Rojo collects additional clues as she systematically documents why and how Spaniards would take up native origin stories and make a return to Aztlan their own goal—and in doing so, overturns the traditional understanding of Nuevo México as a concept and as a territory.
