Intrepid Potash, Inc. (NYSE: IPI), based in Denver, Colorado, is a fertilizer manufacturer. The company is the largest producer of potassium chloride, also known as muriate of potash, in the United States. [1] It owns three mines, all in the Western U.S., near the cities of Carlsbad, New Mexico, Moab, Utah, and Wendover, Utah. [2]
The Permian Basin deposit includes the major mines outside of Carlsbad, New Mexico, to the world's purest potash deposit in Lea County, New Mexico (near the Carlsbad deposits), which is believed to be roughly 80% pure.
Early studies by Udden, and the presence of potash in the Santa Rita well between 1,100 and 1,700 feet, led to the United States Geological Survey exploring the area in search of potash, which was highly important during World War I as the US could no longer import it from Germany. By the mid-1960s, seven potash mines were operating on the New ...

United States Potash Company Engine Number 3 on display at Fairplex (Pomona, California) The United States Potash Railroad was a 3 ft (914 mm) narrow gauge railroad built in 1931 to carry potash from the mines to the mill at Loving, New Mexico where the Atchison, Topeka & Santa Fe Railroad had a spur that went out to the refinery to carry out the processed potash.
By earliest Permian time, during the Wolfcampian Epoch, the ovoid shaped subsiding Delaware Basin extended over 10,000 square miles (26,000 km 2) in what is now western Texas and southeast New Mexico. [1]: 193§1 This period of deposition left a thickness of 1,600 to 2,200 feet (490 to 670 m) of limestone interbedded with dark-colored shale.
The mine was started as the Chino Copper Company in 1909 by mining engineer John M. Sully and Spencer Penrose, [1] [2] [3] and is currently owned and operated by Freeport-McMoRan Inc. subsidiaries. The area where the mine is located is at an average elevation of 5,699 feet (1,737 m).
It occurs in sedimentary marine evaporites and is a major potassium ore mineral in the Carlsbad deposits of New Mexico. It is also present as a 2–3% contaminant of Himalayan salt. The only deposit currently being mined lies under North Yorkshire, UK, extending under the adjacent North Sea.
