Soda Springs in Caribou County, Idaho — The American West (Mountains)
Conda Mine - A phosphate fortune unearthed
During the 1920s, world-wide demand for metals increased and mining activity boomed.
Phosphate rock suitable for agricultural fertilizer and industry was abundant in the Soda Springs area. In 1919, the Anaconda Copper Mining Company purchased 3,500 acres of phosphate-rich mining claims for $650,000 in the hills northeast of Soda Springs and mining was underway.
In 1940, in response to the World War II effort the Conda Mine took the national lead in vanadium production. Vanadium is a rare but important by-product of manufacturing phosphate fertilizer that is added to steel to make high-grade armor, bullets, and bombs.
In 1959, Idaho's J.R. Simply Co. took over the open-pit phosphate mining at Conda in a joint venture agreement with Anaconda, and a year later Simplot purchased the plant. Fewer employees were required and the population at Conda dwindled. In 1984, phosphate mining at Conda ceased.

Also see . . . History of the Conda Operation: Underground to Strip Mining - AAPG Datapage. The Anaconda Copper Mining Company ac- quired the claims in 1919 and 1920, and began underground development in the later year. A railroad spur from Soda Springs was constructed, a townsite was laid out, and a surface crushing plant was installed. The rock subsequently mined was shipped to Anaconda, Montana for manufacture of phosphate fertilizers. (Submitted on August 7, 2017, by Barry Swackhamer of San Jose, California.)
