Passport Potash Continues Expanding the Deposit with Infill and Expansion Drilling Results

VANCOUVER, BRITISH COLUMBIA--(Marketwire � May 10, 2012) - Passport Potash, Inc. (TSX VENTURE:PPI)(OTCQX:PPRTF) is pleased to report that it has received analytical results from the first two wells drilled and cored as part of its 2012 drilling program. Analyses completed at the Saskatchewan Research Council Laboratories in Saskatoon, Canada returned 3.05 metres of 17.07% KCl from drill hole PPI-2012-01 and 1.99 metres of 16.82% KCl from drill hole PPI-2011-31. Included within the potash interval of PPI-2012-01 were 0.99 metres of 27.83% KCl which included 0.23 metres of 45.43% KCl. Included within the potash interval of PPI-2011-31 were 0.70 metres of 28.37% KCl which included 0.17 metres of 41.00% KCl. (See Table 1).  Drill intercepts are believed to represent true thicknesses asthe wells were drilled vertically and the potash beds are essentially flat lying. 

Hole 12-01 and Hole 11-31 are part of an expansion and in-fill drilling program designed to expand the recently released resource as defined in the NI 43-101 Technical Report prepared by ERCOSPLAN. The primary objectives of the current drilling program are to increase the overall number of drill holes to be included in a future resource calculation and to decrease the spacing between existing drill holes. These actions will lead to an increased level of confidence that the potash mineralization is continuous, and to the potential expansion of the future resource calculation. *

Passport Potash President and CEO Joshua Bleak commented: "We are extremely pleased with the results as we continue with our current drill program to further define our resource. These two results will be added to our resource calculation and help to define the deposit of which we currently only have a calculation for 40% of our total land package. Once we complete our 2012 drill program, we anticipate our updated resource calculation will cover a much greater percentage of our land holdings."

About the Holbrook Potash Project
Passport Potash Inc. is a TSX-listed resource company engaged in the exploration and development of advanced potash properties. Passport has acquired a strategic position in the Holbrook Basin with land holdings encompassing over 86,000 acres.

Quality Assurance and Quality Control
The standard operating and quality assurance procedures followed by Passport Potash employees have been instituted to make sure that all sampling techniques and results meet international reporting standards.  Coring starts when the first significant gypsum interval (Upper Supai Formation) is intersected.  Information about the drill holes and the on-site core descriptions are conducted according to international standards (depth intervals, recovery %, lithology, structure, alteration, rock type, weathered profile, sample intervals, remarks).  Onsite field geologists collect the cuttings, bag and label them and place a small sub-sample into a chip tray for further treatment.  Directly after being retrieved the cores are measured, cleaned, filed logged, packed in plastic poly sheeting and placed into sequentially numbered and labeled core boxes.  Material is temporarily stored prior to transfer to the core facility in Apache Junction, Arizona, where significant intervals are dry cut in half.  Half core samples are then bagged and carefully packed into boxes and shipped to the Saskatchewan Research Council in Saskatoon.
Passport is utilizing SRC�s Potash ICP Analysis package designed for multi-element analysis of potash samples.  SRC includes blanks, duplicates and their internal potash 003/004 standards in the analysis.  SRC�s analytical procedures have been more fully detailed in the NI 43-101 Technical Report, dated 30 March 2012, prepared for Passport Potash by ERCOSPLAN Ingenieurgesellschaft Geotechnik un Bergbau mbH. SRC is an ISO/IEC 17025:2005 certified facility.
