Daniel Cowan Jackling proved large scale mining of low-grade deposits could be economic. With the financial support of risk-tolerant investors, Jackling built the first commercial scale copper mining and milling operation at the Bingham Canyon mine near Salt Lake City, Utah in 1903. The success at Bingham Canyon led to the Utah Copper Company which, with the help of Guggenheim interests, ultimately joined the Kennecott Copper Company. In addition to the spectacular success of the Utah Copper Company, Jackling led the development of the Chino Mining Company in New Mexico, the Ray Mine in Arizona, and the Robinson Mine in Nevada. His ownership stake and dividend stream from these operations and others led to Jacking becoming a self-made millionaire before he was 40 years old. His technical contributions to the mining industry are well documented and recognized in many ways. This presentation is about his lifestyle after his sudden affluence in the early 1900’s, near the tail end of the Gilded Age. Socialites, personal rail cars, yachts and hotel suites helped Jackling take a time out from his prodigious workload. Or integrate one or more these indulgences into his business routine.
