Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 44, p. 211. See also Enrique Morel Donoso, "The Chuquicamata Complex" in B A Kennedy (ed), Surface Mining (2nd Edition) (Baltimore, MD: Port City Press, 1990), p. 1140. Works number was 39773 in May 1913.
Ordered by the American Smelting and Refining Company, this oil-burning Prairie tank was headed for dry back country that frequently called for auxiliary water supply. A note accompanying the order stated: "With this locomotive we are to ship an extra tender which will sometimes be coupled up to this loco. See that proper connections are provided for this purpose." The engine was a duplicate of an engine supplied to the Tecopa Railroad in Nevada in 1910 (See Locobase 15951).
The copper deposits in the Atacama deserts that would become known as the Chuquicamata lode had yielded useful ore even before the turn in the 20th Century, but it was Alfred C Burrage's description of the probable extent of the deposits that led the Guggenheim Brothers to form the Chile Exploration Company on 11 January 1912. Morel Donoso notes that their expectations were not disappointed.
