Passport Potash Inc. Updates Current Drilling Program

VANCOUVER, BRITISH COLUMBIA, Dec. 15, 2010 (Marketwire) -- Passport Potash Inc. (TSX VENTURE:PPI) is pleased to announce that it has completed the first drill hole of its 2010 drill program. This hole represents the first exploration for potash within the boundaries of the Twin Buttes Ranch in more than 45 years. Potash was intercepted in this hole and has been confirmed by both visual inspection and by downhole geophysical logging.

This hole is located within the Twin Buttes Ranch in an area where there has been no previous drilling. Upon completion of drilling and logging, the hole has been converted into a producing water well. Water is present in the well and will be used in the ongoing drill program at a considerable cost saving to the company. The company has also set up a field office at the well site and this area will now serve as a base of operations from this point forward.
