Operations
90,000 Acres of State and Private Leases Under Operation in Arizona’s Holbrook Basin
Potash Arizona, Inc. is advancing plans to develop, build, and operate a conventional potash mine and state-of-the-art production facility. This decision is driven by several strategic and competitive advantages, including the shallowness of the deposit, established infrastructure, and proximity to year-round markets.
We are committed to conducting our operations in a manner that protects the environment and safeguards our employees and the public from unacceptable risks. Through integrated business planning, clear goals, and responsible decision-making, we aim to support sustainable development—conserving resources, maximizing the value of what we extract, and enhancing environmental, social, and economic outcomes.
The Holbrook Basin Lies 30 Miles East of Holbrook, Arizona, Adjacent to I-40
The Holbrook Salt Basin, located in eastern Arizona, lies within the Permian-aged Supai Salt Formation. This formation is divided into five distinct cycles, with Cycle 5, the uppermost layer, hosting significant potash mineralization.
Mineralized zones are typically found at depths ranging from 800 to 2,000 feet (243 to 609 meters) below the surface. Potash, primarily in the form of sylvite, is usually concentrated in the upper parts of these evaporite sequences.
This depth profile is comparable to the Carlsbad potash mine in New Mexico and is considered relatively shallow compared to many other potash basins worldwide—offering potential advantages in development and operating costs.
