Holbrook Basin Project


The Holbrook Basin project is located 7 miles east of Holbrook, Arizona.  The project sits atop a large salt basin that is known as the Holbrook Salt Basin.  In the 1960’s and 1970’s Arkla Exploration Company and Duval Corporation drilled more than 100 holes exploring for potash in the Holbrook Basin.  Arkla and Duval reported the presence of the potassium minerals sylvite (KCl), carnallite (KMgCl3), and polyhalite (K2Ca2Mg(SO4)4*2H2O).  In August 2008 the Arizona Geological Survey published an open file report (OFR 08-07), based on its review of the historic drilling data, which suggested the potential for further potash exploration in the Holbrook Basin.
