The Sevier Playa project is located in the central portion of the state of Utah, approximately 140 miles southwest of Salt Lake City.
Situated in the barren landscape of the west desert generally between the towns of Delta and Milford, this dry lake is approximately 26 miles long by an average of 8 miles wide, and covers an area of approximately 130,000 acres.
The Sevier Playa is an endorheic or terminal basin, meaning that all surface water within the Sevier Playa watershed terminates here.
Because there is no drainage from the playa, minerals eroded from the surrounding soils have become concentrated over geologic time to create a vast, mineral-rich brine that is known to contain potassium, sulfate, and other beneficial minerals.
Either directly or through agreements, Crystal Peak controls the project via leases on more than 124,000 acres on the Sevier Playa. Crystal Peak acquired these leases from the Utah School and Institutional Trust Land Administration and from the U.S. Department of the Interior. All leases were acquired by competitive bid.
Using an industry proven, cost-effective solar evaporation process, Crystal Peak is focused on the development and production of sulfate of potash, a premium-priced, specialty fertilizer used for high value crops, arid soils, and other beneficial products.
What is Potash?
Potash is fertilizer primarily found in two forms: muriate of potash or KCl, and sulfate of potash or K2SO4. Both forms provide potassium (K), a necessary nutrient for all plant and animal life.
About 90% of all potash produced in the world is used as fertilizer with the remainder being used mostly in the chemical industry.
The Sevier Playa is being designed to produce sulfate of potash and other beneficial minerals.
Sulfate of Potash
Potassium sulfate, or sulfate of potash, is used in the production of high-value crops such as tree nuts, fruits, berries, and many vegetables. For some applications, such as chloride-sensitive crops or very dry soils, potassium sulfate is the preferred or only potassium fertilizer a farmer can apply.
These include the Great Salt Lake in Utah, the Atacama Desert in South America, Xinjiang in China, the Danakil Depression in Africa, in Western Australia, and at the Sevier Playa in Utah where Crystal Peak is hard at work.
The demand for potassium sulfate is expected to increase substantially over the coming years as increasing populations, reduced arable land, improving diets, and a greater interest in organic and environmentally friendly foods drive consumption.
Crystal Peak plans to produce a suite of useful products from the brines found at the Sevier Playa. Using an environmentally friendly solar evaporation process, the company expects to produce potassium sulfate, magnesium chloride, and sodium chloride.
Additional research may lead to the development of other beneficial chemicals and nutrients from the brines at the Sevier Playa project.
