Passport Potash, Inc. to Expand Holbrook Basin Exploration Program

Vancouver, B.C. March 31, 2011. Passport Potash, Inc. (PPI: TSX.V, OTCQX:PPRTF) announces that it will be expanding its Holbrook Basin, Arizona exploration program in connection with the option agreement entered into with Ringbolt Ventures Ltd. (TSX-V:RBV).  The option agreement will allow Passport to acquire a 100 percent interest in 15,994.32 acres of Ringbolt’s mineral exploration permits and to conduct a $2.25 million (U.S.) exploration program on the optioned property.


Preliminary assessment of Passport’s work plan indicates that the expanded exploration program could include 10 new drill holes and a 25-line mile seismic survey on the option property.  This new exploration program would increase Passport’s total drill holes to more than 30, with75-plus line miles of seismic survey.

Passport’s current exploration program is being conducted on Passport’s holdings in the western portion of the Holbrook Basin.  Zonge International’s seismic crew has completed data acquisition for the 50 line-mile seismic survey on Passport’s land holdings in the Holbrook Basin.  Additionally, seven exploration drill holes have been completed at the Twin Buttes Ranch.  Down hole geophysical and assay results from these drill holes will be presented in the NI 43-101 technical report being prepared by SRK.

Passport president Joshua Bleak stated “Passport is looking forward to exploring the eastern side of the Basin.  Some of the thickest portions of the potash deposit are located in this portion of the Basin, and we anticipate this property to significantly add to the value of our Holbrook Basin project.”
