Passport Potash received permits from the Arizona Oil and Gas Conservation Commission to drill 8 exploratory coreholes on the Twin Buttes Ranch property near Holbrook to evaluate the potash potential. AZGS issued the permits on behalf of the Commission. In 2008, AZGS released a report showing that vast potash resources may underlie the area. [right, credit Passport Potash]
