Braden Copper Company was an American company that controlled the El Teniente copper mine in Chile until 1967 when its copper holdings were nationalized.
History
Braden Copper Company was founded on 18 June 1904 by E.W. Nash, Barton Sewell, William Braden and other mining partners. Braden visited the mine during the winter of 1903-1904. Using capital of $625,000, the company purchased the mine and developed a mill at Sewell, Chile. Production started on 1 June 1906.[2] Barton Sewell never visited Chile and was limited to participating in the business as an upper executive at the companies central offices in New York City.
After E.W. Nash died in 1905, Braden turned to John Hays Hammond and Guggenex, owned by the Guggenheim brothers, for financing. Braden Mines Company was formed on 10 July 1909. In June 1910, the Guggenheims took control of the mine and provided financing which turned the oxcart road into a railway, built a three-thousand ton mill and hydroelectric plants. Kennecott Copper Corporation acquired 99 percent of Braden Copper Mines Company in 1915.[2]
