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.


Potash originally referred to as wood ash. Potassium carbonate, a basic chemical of pre-modern times, was extracted from it. Today potash refers to potassium compounds and potassium-bearing materials, the most common being potassium chloride (KCl). The term “potash” comes from the practice of extracting potassium fertilizer (K2CO3) by leaching wood ashes and evaporating the solution in large iron pots.


Potash, or carbonate of potash, is the common term used for the fertilizer forms of the element potassium (K).


Potassium occurs abundantly in nature, being the 7th most common element in the earth’s crust. Some clay minerals which are associated with heavy soils are rich sources of potassium.


Potash bearing rock deposits are derived from the minerals in ancient seas that dried up millions of years ago. Fertilizer potash is mostly derived from these potash rocks. It requires only separation from the salt and other minerals
