About the Holbrook Potash Project

The Holbrook Basin is known to contain a 600 square mile potash bed in the Permian Supai Formation as documented by the Arizona Geological Survey (AGS) Open File Report 08-07. The potash bed was drilled and delineated in the 1960s and 1970s by Duvall Corporation and Arkla Exploration. Due to low potash prices in the 1970's the Holbrook Basin potash bed was not developed after discovery. Below is a link to the AGS report summary:
