Two companies have added a total of nine more core holes to their potash exploration programs in the Holbrook basin of eastern Arizona. Southwest Exploration/Passport Potash had 4 drilling permits approved by the Arizona Oil and Gas Conservation Commission this week; HNZ Potash had 5 permits approved.
At last report, 4 drill rigs were at work in the basin, working for these two companies and American West Potash. [right, AZGS potash viewer, showing permitted core holes in the deposit]
